What categories are included in the technical requirements in the general assembly drawing of the switch and socket mold?

After drawing the sketch of the switch and socket mold, the mold design engineer will start to draw the general assembly drawing of the switch and socket mold assembly drawing. The general assembly drawing will generally indicate the mold size, name, material, shrinkage rate, special requirements, etc. It is important to indicate some technical requirements of the switch socket mold during the manufacturing process. for example:

Basic introduction to plastic molds

A combined plastic mold for compression molding, extrusion molding, injection molding, blow molding and low-foaming molding, which mainly includes a die combination base plate, a die combination and a die combination card with a variable cavity. The punch is a punch with a variable core, which is composed of a punch combination base plate, a punch assembly, a punch combination card board, a cavity cutting assembly and a side section combination plate. Coordinated change of mold convex, concave mold and auxiliary forming system. It can process a series of plastic parts of different shapes and sizes. In the plastic processing industry, it is matched with plastic molding machines to give plastic products a complete configuration and precise size tools. Due to the variety of plastic varieties and processing methods, and the complex and simple structures of plastic molding machines and plastic products, the types and structures of plastic molds are also diverse.

What maintenance should be done for injection molds in normal and in the process of use

(1) It is necessary to clean the oil stains and rust on the surface of the mold and check whether there are foreign objects in the cooling water holes of the mold, and whether there is a waterway blockage.

How long does it generally take to mold injection molding

From mold design to injection molding, how long is the time period? This is a question that many customers are more concerned about. After all, time is efficiency, and the shorter the time, the less the cost. Regarding this time issue, we need to analyze and understand it from the perspective of multi-dimensionality. For example, if the product structure, size, requirements, product material, specific production quantity and so on. What are the specific, let's take a look:

What is the future development trend of plastic molds?

　In many industrial and daily products, molds are an indispensable part. Many industrial products, including daily necessities, are completed by molds. In modern mass production, without high-level molds, there will be no high-quality products. It also plays an important role in improving production efficiency and reducing production costs for enterprises. According to the latest foreign statistical analysis, 75% of the rough machining of metal parts, 50% of finishing machining and 90% of plastic parts are processed by molds. Therefore, the mold industry is also known as the "crown industry". Today, mold making has become an important part of advanced manufacturing technology.

What factors affect the polishing of plastic molds

Plastic products are already very common products in production and life, including many industrial products that also use plastic raw materials. Some products have very high requirements on appearance, which requires mirror polishing of product molds in the process of manufacturing and processing. Plastic mold polishing can not only meet the requirements of product appearance gloss, but also improve product corrosion resistance. resistance and wear resistance. Therefore, mold polishing is of substantial benefit to the product. So how to polish the mold well, and what are the specific influencing factors, today we will focus on this content.
