Injection mold usher in a new round of development opportunities

Release date:2017-08-09 Author: Click:

Modern mold industry has "not fall to death industry," said. The world mold market as a whole in short supply, the market demand remained at 60 billion to 65 billion US dollars at the same time, China's mold industry also ushered in a new round of development opportunities.


The mold cavity, and cooling in the cavity stereotypes, and then separate the upper and lower mold, the top of the system will be the top of the mold from the mold to leave the mold, the last mold and then closed for the next injection, the injection process is the cycle.


General plastic mold consists of a moving mold and a fixed mold. The movable mold is installed on the moving template of the injection molding machine and the fixed mold is installed on the fixed mold of the injection molding machine. During injection molding, the movable mold and the fixed mold are closed to form a pouring system and a cavity. When the mold is opened, the movable mold and the fixed mold are separated to remove the plastic product.


Although the structure of the mold may vary due to the variety and properties of the plastic, the shape and structure of the plastic, the type of the injection machine, etc., the basic structure is the same. Mold mainly by the pouring system, temperature control system, forming parts and structural components. One casting system and molding parts are in direct contact with the plastic part, and with the plastic and products change, is the most complex mold, the most varied, requiring the highest processing finish and precision part.
In the mold injection process, the gate sometimes sticks in the sprue, it is not easy to come off. Resulting in cracked products when the mold is damaged. The operator must use the tip of the copper rod to knock out from the nozzle to release the broken plastic before releasing it, which will seriously affect the production efficiency. The main reason for this failure is the poor quality of the tapered bore of the sprue bushing, and sometimes there is a knife mark in the circumferential direction of the bore. Followed by some injection molding material is too soft, then the mold of the sprue in the use of the tapered end of the small end deformation or damage, if the sprue sleeve mouth spherical arc is too small, will cause the gate feed here produces riveting head. Cone hole taper sleeve more difficult to process, should try to use standard parts, if you need to self-processing, but also use their own production or purchase of special reamer.
Guide the main role in the mold from the fixed and guide to ensure that the mold core and cavity forming parts do not collide with each other in any case, but must not be used as a guide pillar as a force point or positioning of the workpiece . For example, during injection, fixed mold will have a huge lateral deflection force: plastic parts wall thickness requirements of non-uniform, the flow rate through the thick wall at a large pressure here; produce plastic side if Asymmetric words, such as the ladder-shaped distribution of parts of the mold, opposite the opposite sides of the mold subjected to the back pressure is not equal.
Mold production technology level, has become a measure of a country's manufacturing level is an important symbol of one of the high, because the mold to a large extent determines the quality of products, benefits and new product development capabilities. China mold industry has developed very actively in recent years, of which the overseas export market is an indispensable part of the development of China's mold industry. It is learned that at present, Hong Kong still accounts for the largest share of China's export market, followed by Japan and the United States , The sum of the three is nearly half the total amount of China's mold exports, but most of China's exports of mold products are low-end products, developed countries in Europe and the United States high-end market, the share of Chinese products is still very low. Therefore, China's mold industry to actively improve product quality to further improve the mold products in overseas markets share, thus further promoting their own development.
Therefore, China's mold products want to enter the international market in depth, and continue to open up new sales areas, but also China's mold manufacturers in the mold on the quality of more efforts. 【Suzhou mold design
