Description

Slide core-pulling injection molding bicolor mold

Technical Field

The utility model relates to the technical field of molds, in particular to a slide core-pulling injection double-color mold.

Background

The mould line position generally refers to a line position mechanism of a mould, namely a mechanism capable of obtaining lateral core pulling or lateral parting and resetting actions to drag out positions of inverted buckles, sags and the like of products, and the mechanism utilizes the molded mould opening action to enable a diagonal bracing tip and a sliding block to generate relative movement trend, so that the sliding block is separated from an inverted hook along two movement modes of a mould opening direction and a horizontal direction.

In the production of products, conducting or semi-conducting structures such as holes and channels often appear, and a mold core corresponding to the structures is generally required to be arranged in a mold, so that the structures are prevented from being sealed. The injection mold of the product comprises a core-pulling and fixing mold structure, and the difference is that the core-pulling injection mold can draw out a mold core corresponding to the conducting or semi-conducting structure to form the mold core; however, the core-pulling die needs to reasonably control the operating bit rate of core pulling, so that structural damage caused by insufficient molding or too fast core pulling is avoided; and the injection molding molten materials in the double-color mold can have variability, so that the problems are more easy to occur, the damage or splitting of a double-color intersection area is easy to cause in the core pulling process, and the molding of a product is directly influenced. In order to obtain a more stable slide core pulling structure, the yield of injection products of the bicolor mold is improved. In view of the above, we propose a slide core-pulling injection double-color mold.
