A floating cavity mold for producing automobile generator rectifier bridge support

Abstract

The invention discloses a floating mold cavity mould for producing a vehicle engine rectifier bridge bracket. A moving mold and a fixed mold of the floating mold cavity mould are provided with product mold cavities; a placement groove is formed beside the product mold cavity of the moving mold; a floating mold cavity block consists of a molding cavity and a base; the placement groove is matched with base; when the base of the floating mold cavity block is arranged in the placement groove, and the moving mold and the fixed mold are closed, the floating mold cavity in the floating mold cavity block is combined with the product mold cavities of the moving mold and the fixed mold to form a closed overall product mold cavity. When plastics is injected into the mold cavities, the floating mold cavity block and a product are combined into a whole; the floating mold cavity block and the product can be taken out from the mould together after the injection is completed for 10 seconds; the floating mold cavity block is cured and cooled out of the mould with the product and is separated from the product out of the mould. The mould is simple in structure; the manufacturing cost of mould equipment is saved; the cost of the mould is saved by 35 percent; the cost of the equipment is saved by 10 percent; energy resources are saved; the production period of each product is reduced by 40 seconds; the energy consumption of each product is saved by 80 percent.

Description

technical field [0001] The patent of the present invention relates to a production mold for a rectifier bridge bracket of an automobile generator, especially a floating cavity mold for producing a rectifier bridge bracket of an automobile generator. Background technique [0002] The core-pulling part of the rectifier bridge bracket is mainly the socket part. The plastic thickness of the socket part is relatively thick and the shape is irregular. There are three metal inserts in a straight line inside. During injection molding, it depends on the mold cavity to be shaped for 50 seconds before cooling. Die, to ensure the height dimension of the three metal inserts and the linear position dimension requirements; at the same time, ensure that the plastic layer with uneven thickness does not shrink and deform. At present, the production of injection molds for automobile generator rectifier bridge brackets adopts the traditional inclined slider side core pulling method to realize t...
