The shape of the mold determines the shape of the products, and the processing quality and precision of the mold determine the quality of the products.

The molds at the present stage are mainly divided into hardware molds, plastic molds and special molds thereof according to the difference of the materials to be molded. Among them, a plastic mold, that is, a common injection mold, is a short name for a combined mold used for compression molding, extrusion molding, injection, blow molding and low-foaming molding. The coordination change of the male die, the female die and the auxiliary forming system of the die can process a series of plastic parts with different shapes and sizes.

The injection mold mainly comprises a fixed mold and a movable mold. The fixed mold part is arranged on a fixed workbench of an injection machine and is kept still all the time in the injection molding process. The movable mold part is arranged on a movable workbench of the injection molding machine and can move through a mold closing system of the injection molding machine in the injection molding process. When the injection molding is started, the mold closing system drives the movable mold to move towards the direction close to the fixed mold. And the fixed mold is matched with the parting surface. After closing, a cavity and a pouring system which are consistent with the shape and the size of a product are formed between the movable mold and the fixed mold, the injection machine injects plastic melt into the cavity through the pouring system so that the cavity is filled with the plastic melt, and after pressure maintaining, feeding and cooling shaping, the mold closing system drives the movable mold to move towards the direction far away from the fixed mold, so that the movable mold and the fixed mold are opened from a parting surface, and a plastic part moves along with the movable mold. When the movable mould retreats to a certain position, the demoulding mechanism inside the movable mould pushes the plastic part to be separated from the novel mould, and therefore the finished plastic part is obtained.

However, when the plastic product has side holes and undercuts which are not aligned with the direction of opening the mould, the corresponding part of the forming mould must have laterally movable parts in order to release the laterally formed parts before demoulding. The whole mechanism for driving the lateral forming part to move leftwards and rightwards becomes a lateral parting and core-pulling mechanism.

The conventional lateral core pulling mechanism mainly comprises a core, a driving piece driving the core to slide and a fixing frame for mounting the driving piece, wherein the fixing frame is mainly fixed through bolts. However, the existing connection mode between the fixed frame and the movable mould mainly depends on bolts. However, the bolt is fixed only by the bolt, and the bolt is easy to reverse and loosen in the long-term operation process, so that the installation stability of the lateral core pulling mechanism is affected.
