Shaped inlay part and its making method

Abstract

The invention discloses an insert molding, which comprises an insert and a plastic piece. The insert comprises a main body part and an extended part; the extended part extends outwards horizontally from one end at one side of the main body part; the extended part is provided with a protruding part at a place near the side of the center of the main body part and far away from the outside periphery; part of the plastic piece wraps the insert, and a bulged part is formed on the plastic piece at a side opposite to the protruding part. The invention also provides a method for manufacturing the insert molding. The insert molding has relatively high mechanical strength, which prevents cracks during assembly.

Description

technical field [0001] The present invention relates to an injection molded product, in particular to an insert molded product and a preparation method thereof. Background technique [0002] Insert molding refers to inserting pre-prepared inserts of different materials into the mold and then injecting plastics. The inserts of different materials are generally metal or inorganic solids. Methods of forming composite products. Insert molding can make complex and delicate composite products by taking advantage of the ease of molding and bending of plastics and the rigidity and heat resistance of inserts of different materials. The use of insert molding can save complicated processes such as subsequent assembly and sealing, and greatly improve production efficiency. At the same time, since processing steps such as adhesive coating and mechanical fixing are omitted, the manufacturing cost can be saved. Today, insert molding is widely used in electronic components, electrical co...

AI Technical Summary

Problems solved by technology

The bonding line formed at A of the above-mentioned insert molding product 10 coincides with the extension direction of the side surface of the extension portion 124 of the insert 12 near the center of the main body portion 122, so the mechanical bonding strength at A is relatively poor.

The above-mentioned insert molded product 10 is extruded and deformed greatly during the assembly process, and the residual stress is accumulated, and under the external force applied by the assembly, it is easy to crack at the joint line where the plastic flow converges, thereby greatly reducing the cost of the insert molding. Yield of product 10
