Description

A stable installation injection mold

technical field

The utility model relates to the technical field of injection moulds, in particular to a stable installation type injection mould.

Background technique

All kinds of tools and products used in daily production and life, ranging from the base of the machine tool, the shell of the fuselage, to the shell of a blank head screw, button and various household appliances, all have a close relationship with the mold. The shape of the mold determines the shape of these products, and the processing quality and precision of the mold also determine the quality of these products.

According to the different materials to be formed, the current molds are mainly divided into metal molds, plastic molds, and their special molds. Among them, plastic mold, also known as injection mold, is the abbreviation of a combined mold for compression molding, extrusion molding, injection molding, blow molding and low foam molding. The coordinated changes of the mold convex, concave mold and auxiliary molding system can process a series of plastic parts of different shapes and sizes.

The injection mold mainly includes two parts: fixed mold and movable mold. The fixed mold part is installed on the fixed table of the injection machine and always remains stationary during the injection molding process. The movable mold part is installed on the moving table of the injection machine, and can be moved by the mold clamping system of the injection machine during the injection molding process. At the beginning of injection molding, the clamping system drives the movable mold to move toward the fixed mold. And the parting surface is in fixed mold butt joint. After the butt joint, a cavity and a gating system consistent with the shape and size of the product are formed between the movable mold and the fixed mold. The injection machine injects plastic melt into the cavity through the gating system, so that the plastic melt fills the cavity. After pressing, feeding and cooling, the clamping system drives the moving mold to move away from the fixed mold, so that the moving mold and the fixed mold are opened from the parting surface, and the plastic parts move together with the moving mold. When the movable mold retreats to a certain position, its internal demolding mechanism pushes the plastic part out of the new model, thereby obtaining the finished plastic part.

However, when the plastic product has side holes and undercuts that are inconsistent with the opening direction of the mold, the corresponding part of the molding mold must have parts that can move laterally, so that the side molding parts can be released before demolding. The whole mechanism that drives the left side movement of the side molding part becomes the side parting and core pulling mechanism.

A conventional lateral core-pulling mechanism mainly includes a core, a driving member for driving the core to slide, and a fixing frame for installing the driving member, wherein the fixing frame is mainly fixed by bolts. However, the existing connection method between the fixed frame and the movable mold mainly relies on bolts. However, only by means of bolts for fixing, in the long-term operation process, the bolts are prone to reverse and loosen, thus affecting the installation stability of the lateral core-pulling mechanism.
