Li Zhongxin has always had his principles of doing things.

As long as he wants to do something, he must do it perfectly, and he must do it thoroughly.

There is no best, only better is one of Li Zhongxin's goals all along, although Li Zhongxin looks lazy and lazy on weekdays, but if he really decides to do something, he really works hard.

When Li Zhongxin was in later generations, although he put a lot of effort into studying the production of fan blades for electric fans, it was many years ago, and Li Zhongxin did not have much confidence in whether he could make a suitable mold.

But what! As long as it can be made according to the drawings drawn by Li Zhongxin, there is a 90% chance that such a good mold will be made.

As long as the effort is deep, the iron pestle is sharpened into a needle.

After Li Zhongxin decided to make a mold drawing for the fan, he began to study the drawing without sleep.

In order to better make the drawing of this fan blade, Li Zhongxin asked Wang Bo to contact Yan Ming, the chief engineer of Jiangcheng Mold Factory, and Chen Tianfang, the chief engineer of Jiangcheng No. 1 Plastic Factory, and asked the two of them to assist him in studying and slowly drawing the drawing.

Yan Ming, an engineer of Jiangcheng Mould Factory, is an expert in Jiangcheng molding, once a model worker in Jiangcheng, and a college student who specializes in learning molds.

Chen Tianfang, an engineer of the First Plastics Factory, is an engineer of the Plastics Factory, and he also has a unique understanding of the research on plastic molds, and is the backbone of the First Plastics Factory and the first genius of the First Plastics Factory.

The three stinkers were Zhuge Liang, and under the model of Li Zhongxin's later memories, the three of them finally drew the approximate map that Li Zhongxin wanted after more than half a month of hard work.

Li Zhongxin called the flow channel in which the plastic melt is directed from the nozzle of the injection machine to the cavity developed by the three of them as a gating system.

This system consists of sprue, manifold, gate and cold well. In order to ensure that when the moving mold and the fixed mold are closed, the guide pillar and guide bushing are usually arranged on the moving mold and the fixed mold respectively.

The deep cavity injection mold must also be positioned on the main parting surface, and sometimes guide parts are also set to ensure the accurate movement and reset of the demoulding mechanism.

The demoulding mechanism is the mechanism that takes the plastic parts out of the mold in the later stage of the mold opening process.

In addition to these, Li Zhongxin also designed a lateral parting core-pulling mechanism. It is a type of plastic part with a side concave or side hole, and between the molds that are removed, it must be laterally parted or the lateral punch or the side core extracted.

In order to meet the requirements of the injection process for the mold temperature, the mold is equipped with a temperature adjustment system for cooling or heating rate.

For mold cooling, a cooling channel is generally set up in the template, and a heating element is installed in or around the mold, and the injection mold must be equipped with an automatic mold temperature adjustment device.

In order to discharge the original gas in the cavity during the injection filling process, an exhaust groove is often set up at the parting surface. The exhaust volume of the cavity is not large, and the exhaust can be directly used by the parting surface, or the gap between the ejector rod of the mold or the core and the mating hole can be used.

These things are all things that Li Zhongxin learned when he visited the electric fan factory in later generations and discussed with the technical director of the electric fan factory.

At that time, in order to convince the people in Russia of the quality of the electric fan, Li Zhongxin memorized the design of the electric fan mold by heart, but he did not expect that after being reborn in 82 years, he actually created a precedent for the production of plastic electric fan injection molds.

Li Zhongxin, Yan Ming, and Chen Tianfang spent another week and afternoon to make many careful calculations before they could be regarded as perfecting the drawing of this mold.

At this time, Li Zhongxin even had a feeling that he wanted to vomit when he saw the mapping tool, and he thought a little depressed that it was too tiring to make this thing.

He felt that he had to take a good rest in the recent period to compensate for his hard work in the past few days.

Yan Ming and Chen Tianfang were also tired enough in this week's time, they never thought that one day they would actually make a new mold drawing with a third or fourth grade elementary school student, although this drawing has not yet become a finished product, but they can feel that it will be a miracle to make something through this drawing.

Although the week was very hard, they were still happy with the subsidies given to them by Zhongxin, and they even admitted that if Zhongxin still had such a mapping or modeling task in the future, they would definitely come to help.

Both of them are senior engineers of the unit, and their monthly income at this time is nothing more than forty or fifty yuan, but when they went to Zhongxin Company to help Li Zhongxin complete a mapping work, not only the salary of the unit was opened, but also a generous bonus red envelope.

At that time, when the two of them received the bonus red envelope from Zhongxin Company, their eyes were straight, and they never thought that the bonus of the two of them would reach 500 yuan per person.

What is the concept of 500 yuan for them, it is a whole year's salary, that is, it took them a week to earn the money they were able to earn in a year.

The outsourcing subsidy of five yuan a day made them very happy, and during this time in Zhongxin Company, their food has been greatly improved, and even Zhongxin Company has put down their words, as long as they want to eat, they can order whatever they want.

The brand-new fifty pieces of unity in the bonus red envelope simply made the two of them have a crazy feeling, they felt that the outsourcing work of Zhongxin Company was really good, and if Zhongxin Company still had such outsourcing work in the future, even if they were absent from work at the unit, they would have to come and participate.

After the drawing of the mold was completed, Li Zhongxin went directly to the Jiangcheng Post Office and mailed the drawing by registered mail to Masako Mitsui.

Seeing that there was still some time at noon, Li Zhongxin casually ate a bowl of ramen opposite the Jiangcheng Post Office.

What Li Zhongxin didn't expect was that the ramen he ate tasted very good, the noodle soup looked very light, but it tasted like a thick beef soup.

With the store's flavorful chili peppers, I drank a bottle of sparkling wine, a very popular drink in Jiangcheng at that time. (It's the same thing as a soda, but it has some flavor in it, and it's a very delicious drink at the time.) ）

Thinking of KFC and McDonald's that would spread all over China in later generations, Li Zhongxin put the idea of making a good chain of fast food in his mind.

It's now eighty-two years, and it costs two taels of food stamps to eat a bowl of noodles, and it's not the right time to get fast food at this time, Li Zhongxin feels that at least he should wait until the time is ripe, even if the food is enough, and then study this thing.

Now there are several important aspects, one is the continued creation of comics, and the other is that the company set up with Masako Mitsui will be put into production in the black province as soon as possible to promote these two projects.

The most important thing is that the grocery chain of Zhongxin needs to be upgraded, and the original small chain of grocery stores can no longer satisfy Li Zhongxin's ideas.

At this time, Li Zhongxin not only wanted to open the largest supermarket in Jiangcheng, but also found a suitable place to open it in the provincial capital of Harbin City after the year.

By the end of next year, if he has enough funds, he will set up large supermarket chains in all the four major cities of Hei Province, and he will open large supermarkets throughout the province.

After the large-scale supermarket is opened in the province, if the market recognizes, Zhongxin supermarket will be opened in the major cities of the three northeastern provinces and become the largest supermarket chain in the northeast.

The biggest obstacle to doing this kind of supermarket chain is money and supply, as long as there is money and no problem with the supply, everything else is easy to say.

Thinking that the current supermarket chain has been on the right track, and the goods have been relatively sufficient, Li Zhongxin thought again, many farmers over there in Zhubantun have no work to do after the autumn harvest, since the company is backed by this Zhubantun, most of the company's employees are Zhubantun people, after a period of time to close the river, these people will have nothing to do, this is also a big problem.

He should let the employees of the faithful company and some people who trust the faithful company move, instead of letting them play mahjong or poker and other gambling at this time, and not let these people re-become the bad habits of being lazy and lazy.

Thinking that setting up stalls in the 80s was the most profitable and selling things from house to house, Li Zhongxin immediately thought that the goods sent by Zhongxin Company on the side of Hanzheng Street in Wuhan were very sufficient, and he would add some of these goods to the purchase price and calculate them as wholesale prices for these people, so that these people could set up stalls in the towns and villages below, or go to the nearby towns and villages to sell them from house to house.

In this way, not only can the sales of Zhongxin's goods increase, but also allow these people to have a fairly good income in winter, at least to prevent the kind of Tunzi people who play mahjong or gamble at home in winter.

Only by letting these people move, only by letting them discover that as long as they work hard, they can get rich, then the atmosphere of the whole village will get better and better, and more and more people will do things, so that the lives of the people in Zhubantun and Fulong Village will be better and better in the future.

After Li Zhongxin raised his neck and drank the noodle soup, he realized that he had a lot to do in the future, and there was still a long way to go......
