The definition of Medical plastic injection mold core pulling mould is as follows: Any features that will interfere with the direction of the product and the direction of leaving the mold cannot be demolded. In places like this, it is necessary to remove the interfering steel material after the mold is opened (some Time is before the mold is opened) to remove it first to ensure that the product is smoothly removed from the mold. Therefore, the mechanism that realizes such a function is called Medical plastic injection mold core pulling mould.

Sometimes due to the Medical plastic injection mold project product structure, the lateral core pulling mechanism cannot be used, and a strong release mechanism can be considered. However, the position that cannot be demolded should not be too large, and the molding material is relatively soft, such as PP material.

From the perspective of the front and rear molds, the core pulling mould can be divided into the front core pulling mould and the rear mold core pulling. The structure of the front core pulling mould is a little more complicated than the rear mold core pulling. In the case of cores, try to design as back mold core pulling.

Sometimes the core-pulling mechanism cannot be designed on the inside of the product for the position that cannot be demolded, and it can be considered as a sloping roof. Therefore, the inclined roof is also a kind of mold core pulling.

There are many structures of Medical plastic injection mold core pulling mould, which are ever-changing, such as: inner pulling, outer pulling, oblique pulling, side pulling, and arc pulling. No matter what kind of core pulling, the core idea is to make the steel material that cannot be demolded into the core pulling first, and then the product can be taken out. Otherwise, the product cannot be taken out, and even if it is pulled out hard, the product will be damaged, which is unwilling to accept any customer.
