Abstract

The utility model provides a work piece and punching press work piece composite construction casing of moulding plastics belongs to composite construction casing technical field. The utility model discloses a: the outer surface of the plastic injection molding inner shell follows the inner wall of the metal stamping outer shell, and the plastic injection molding inner shell is fixed in the metal stamping outer shell. The utility model discloses the casing that makes with injection molding process and the casing that makes with stamping process constitute a composite construction's casing, have the advantage of two kinds of technologies concurrently, have overcome plastic products and metal products respective shortcoming. For example, the process of the stamped metal outer shell is simpler, the bonding or welding of a fixing column and a fixing hole is omitted, the plastic injection molded inner shell is supported and protected by the metal outer shell, and the strength is not high.

Description

Injection molding workpiece and stamping workpiece composite structure shell

Technical Field

The utility model relates to a work piece of moulding plastics and punching press work piece composite construction casing belongs to composite construction casing technical field.

Background

The shells, cavities and components of the single injection molding process and the single stamping process are numerous in the actual production process, but each process has certain defects, for example, the strength of the product of the injection molding process is weaker than that of a metal product in the general sense; the processing of the products of the stamping process in the window, the processing of the inner member has problems such as strength, processing, etc.

Single process articles, such as injection molded articles, vary in strength by increasing thickness; such as changing the material to increase toughness; the surface plating changes the appearance. Such as stamped metal products, the window problem is solved by inlaying transparent pieces; the welding member solves the problems of connection, installation, etc.

The strength, toughness and the like of relevant products manufactured by the injection molding process are still different from those of metals, and the defects exist in some occasions that the specific requirements on metal properties can be met or can be met only with low cost. The products of the metal stamping process have complex process, difficult quality control or high cost for processing windows, installation and the like. The window treatment of metal products by stamping process can only be inlaying, welding and bonding processes, and has low strength and complex process

Disclosure of Invention

The utility model aims at solving the problem that above-mentioned prior art exists, and then provide a work piece of moulding plastics and punching press work piece composite construction casing.

The utility model aims at realizing through the following technical scheme:

an injection molded and stamped workpiece composite structural shell comprising: the outer surface of the plastic injection molding inner shell follows the inner wall of the metal stamping outer shell, and the plastic injection molding inner shell is fixed in the metal stamping outer shell.

The utility model discloses the casing that makes with injection molding process and the casing that makes with stamping process constitute a composite construction's casing, have the advantage of two kinds of technologies concurrently, have overcome plastic products and metal products respective shortcoming. For example, the process of the stamped metal outer shell is simpler, the bonding or welding of a fixing column and a fixing hole is omitted, the plastic injection molded inner shell is supported and protected by the metal outer shell, and the strength is not high.
