Abstract

The invention discloses a hockey stick performed product and a hockey stick manufacturing method. The hockey stick manufacturing method is characterized in that a metal support bar is inserted into a rubber membrane tube so that the original silica gel performing mold can be replaced, a joint of the rubber membrane tube is connected into an opening end of the rubber membrane tube in molding, and air having pressure of 2-8kg is fed into an air pressure tube for the air-pressure molding process. The hockey stick performed product and the hockey stick manufacturing method have the characteristics of high repeating utilization rate, low production cost, simple molding processes, stable hockey stick finished product quality, low hockey stick bad product rate and low rejection rate.

Description

technical field [0001] The invention relates to the technical field of sporting goods, in particular to a hockey stick preform tool and a hockey stick manufacturing method with high reutilization rate, stable molding quality and effective reduction of hockey stick production cost. Background technique [0002] The traditional one-piece hockey stick preform includes a silicone stick with a square cross section and an ultra-thin plastic film tube outside the silicone stick. [0003] When forming a hockey stick, first wrap the carbon fiber or glass fiber yarns of different angles and sizes used to form the club on the outside of the preform, and then connect the preform with the batting plate to form a preform; The preform is put into the forming mold, heated and pressed hard, so that the silicone rod is heated and expanded and the ultra-thin plastic film tube is stretched. Blank forming. [0004] The hockey stick molding method in the prior art has the following disadvantage...
