Preparation method of handle with excellent mechanical property

Abstract

The invention discloses a preparation method of a handle with excellent mechanical property. The method comprises the following steps of (S1) putting a first material and a second material into a first hopper and a second hopper separately; (S2) controlling the temperature of a mold; (S3) extruding the first material into the mold and stopping feeding when the feeding amount of the first material is 60-80% of the total volume; (S4) extruding the second material into the mold and stopping feeding when the feeding amount of the second material is 50-70% of the total volume; (S5) feeding the first material again and completely extruding the first material into the mold; and (S6) after the temperature decreases, opening the mold and taking out a product. The feeding order is changed and the problem that a new material and a secondary material can be mixed is solved, so that waste of the material is reduced, the production cost is reduced, and the prepared handle has excellent mechanical property and good overall performance.

Description

technical field [0001] The invention relates to the technical field of handle preparation technology, in particular to a handle preparation method with excellent mechanical properties. Background technique [0002] At present, the injection molding method of the handle is generally a method of injection molding with only one material, or a method of single-material injection with gas-assisted injection. The former injection molding product has a single structure, defective shape, and poor mechanical properties; while the latter requires an increase Although gas-assisted equipment can produce products with relatively complex structures, and has improved shape and mechanical properties, but in this way, the demand for raw materials is relatively large, and because of the use of gas-assisted equipment, it is inevitable that the product will Pores are left on the surface, and subsequent electroplating process is required, which requires sealing of the pores, which not only incre...

Problems solved by technology

[0004] In order to solve the technical problems existing in the background technology, the present invention proposes a method for preparing a handle with excellent mechanical properties, which changes the order of feeding materials, solves the problem that new materials and secondary materials can be mixed, and then reduces the amount of materials used. waste, which reduces production costs, and the prepared handle has excellent mechanical properties and good overall performance
