Maintenance of cosmetics packaging bottle plastic mold

For the purchase of newcomers, the maintenance and maintenance of the mold is more professional, so you need to learn about some basic common sense. You can understand the time for the maintenance time of the mold. Sex, thereby effectively guarantee the instant delivery of orders. Therefore, this article briefly describes the basic common sense of mold maintenance for your reference.

1. Why do you need to maintain the mold

Due to the large variety of products and frequent changes in the processing of injection molding products, after completing a production cycle, the mold is generally stored in the warehouse until the next production cycle comes out. If the preservation of the mold does not pay enough attention, it will cause the mold to rust and decrease the surface smoothness during the preservation period, resulting in a decline in product quality and high waste rate. Great waste.

The use and maintenance of molds accounted for 15 % to 20 % of the effects of mold life. The service life of injection molding molds can generally reach 800,000 times. Some well -maintained molds can even be extended by 2 to 3 times. Therefore, the maintenance of injection molds is very important.

A mold that has been well maintained and maintained can shorten the time for mold assembly and debugging, reduce production failures, stable production operations, ensure product quality, reduce the loss of waste products, and reduce the operating cost of the enterprise and the investment of fixed assets. The current production cycle At the beginning, enterprises can successfully produce qualified products. Therefore, for the processing of injection molding products, in the current market competition, good maintenance of molds can help enterprises.

2. Basic cognition of mold maintenance

Due to the short life of the mold, the working hours and energy waste of steel are caused by the short life of the mold, as well as the huge economic losses caused by the impact of product quality. Therefore, the maintenance of injection molding mold is very important, as follows:

1. Find problems through plastic parts

In the normal operation of injection molding machines and molds, test the various properties of the mold and measure the size of the final molding parts. Through this information, you can determine the existing state of the mold, find the cavity, the core, the cooling system, and the distribution of the division and the division The damage of the type, etc., can judge the damage state and maintenance measures according to the information provided by the plastic parts.

2. Maintenance of mold parts

The technical content of injection molding molds is very high and there are many components. If you do not pay attention to the maintenance and maintenance of various parts during use, it is very prone to damage and rust, causing tens of thousands of or even millions of economic losses. Therefore, pay special attention to the maintenance and maintenance of the mold during the use to ensure the long -term quality of the mold. For this reason, you should first have a resume card for each mold to record, count the use, care (lubrication, cleaning, rust -proof) and damage. Based on this, which components and components can be damaged, and the degree of wear to provide discovery to provide discovery The information and information of the problem, and the molding process parameters and materials used in the mold to shorten the mold test time of the mold and improve production efficiency.

3. Pay attention to the surface maintenance of the mold

It directly affects the surface quality of the product, focusing on preventing rust. Therefore, it is particularly important to use a suitable, high -quality, and professional rust -proof oil. After the mold is completed, the residual injection plastic should be carefully removed according to different methods of injection molding. The copper sticks, copper wire and professional mold cleaning agent can be used to remove the remaining injection molding and other sediments in the mold, and then dry them with the wind. Disable hard objects such as wire and steel strips to avoid scratching surfaces. If there is a rust point caused by corrosive injection, polishing should be performed, and professional rust -proof oil is sprayed, and then the mold is stored in dry, cool, and dust -free.

4. Keep a key tracking detection of several important parts of the mold

The role of the top and guide parts is to ensure that the mold opening and closing movement and the top of the plastic parts. If any part of which is stuck due to damage, it will cause discontinuation. Therefore Lubricant), and check whether the thimble, guide column, etc. occur regularly and surface damage regularly, once discovered, replace it in time; after completing a production cycle, the professional rust oil -proof oil of the mold work, motion, and guide parts should be applied to In addition, the cleanup of cooling roads has a great relationship with production efficiency and product quality. As the production time continues, the cooling tract is easy to deposit scale, rust, silt, and algae, etc., making the cooling flow tract section smaller, narrowing the cooling channel, greatly reducing the thermal exchange rate between the cooling fluid and the mold, increasing the production cost of the workshop. Therefore, the cleanup of water transport cooling runways should be paid attention to.

For thermal flow molds, the maintenance and control of the control system is conducive to preventing the occurrence of production failures, so it is particularly important. Therefore, after each production cycle is over, the heater, heating probe, and thermocouple on the mold are measured with Ohm table. If it is damaged, replace it in time, and compare it with the mold resume to make a record in order to make a record so that so that it can make a record in order to make a record in order to make a record in order to make a record so that so that it can make a record in order to make a record in order to make a record in order to make a record so that so as Find problems in a timely manner and take countermeasures.

When the mold completes the production task, it is necessary to pay attention to the surface maintenance of the mold. It directly affects the surface quality of the product. The focus is on preventing rust and removing dirt. The residual injection plastic should be carefully removed according to different methods. Remove the residual injection molding and other sediments in the mold, and then air dry. Disable hard objects such as wire and steel strips to avoid scratching surfaces. If there is a rust point caused by corrosive injection, use the grinding machine to grind and pollute or use it, and apply rust oil, and then place the mold in a dry, cool, and dust -free place.
