Description

A plastic mold for automobile sheath

Technical Field

The utility model relates to the technical field of automobile jackets, in particular to a plastic mold for an automobile jacket.

Background Art

Plastic mold is the abbreviation of a combined mold used for compression molding, extrusion molding, injection molding, blow molding and low foaming 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 various tools and products used in our daily production and life, from the base and body shell of the machine tool to the embryo head screws, buttons and the shell of various household appliances, are closely related to the mold. The shape of the mold determines the appearance of these products, and the processing quality and precision of the mold also determine the quality of these products. Due to the different materials, appearances, specifications and uses of various products, the mold is divided into non-plastic molds such as casting molds, forging molds, die-casting molds, stamping molds, and plastic molds. For example, when producing automobile covers, plastic molds are needed.

For example, Chinese patent publication number CN209920433U discloses a plastic mold for an automobile sheath, including an upper mold core, a lower mold core connected thereto, a plastic hose and an iron rod jig, wherein the plastic hose is inserted into the iron rod jig, and the other end of the iron rod jig is inserted between the upper mold core and the lower mold core. The utility model has a simple structure and is easy to use. The upper mold core is bounced up by a spring, thereby ensuring the uniformity of the mold during use; at the same time, it saves time, effort, and cycle time, thereby improving labor efficiency and saving labor costs. At the same time, the use of a positioning rod effectively prevents errors from occurring when the upper mold cooperates with the lower mold.

Although the above example can prevent the upper mold and the lower mold from being misaligned when they are engaged by fixing the positioning rod during the production of the automobile cover, during the injection molding process, the temperature of the plastic after the plastic is melted is relatively high, and the mold is in a sealed state after being injected into the mold, resulting in a slow temperature dissipation rate of the plastic, thereby slowing down the molding speed of the automobile cover and reducing the production efficiency. At the same time, when automobile covers of different specifications need to be produced, the existing plastic mold disassembly steps are relatively cumbersome and there are certain inconveniences in use.
