Embodiment Construction

[0045] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0046] like figure 1 , image 3 The embodiment shown is a hockey stick preform, comprising a rubber film tube 10 with a rectangular cross-section and an aluminum alloy support rod 11 arranged in the rubber film tube, the cross-sectional width of the rubber film tube is from the open end to the closed end. The ends of the rubber membrane tube are gradually reduced. One end of the rubber membrane tube is a closed end for connecting with the bat, and the other end of the rubber membrane tube is an open end. The open end is provided with a rubber membrane tube joint 17 for connecting to the wind pressure. The cross-sectional width of the metal support rod matches the cross-sectional width of the rubber membrane tube.

[0047] like Figure 4 , Figure 5 , Image 6 As shown, the rubber membrane pipe joint includes a ventilation pipe 1 with a ventila...

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 3-8kg is fed into air pressure tube so that air-pressure molding process is carried out. 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 and a hockey stick manufacturing method with high recycling rate, stable molding quality and effectively reducing the production cost of the hockey stick. Background technique [0002] A conventional one-piece hockey stick preform includes a silicone stick with a square cross-section and an ultra-thin plastic film tube disposed outside the silicone stick. [0003] When the hockey stick is formed, 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 to the bat to form a preform; The preform is put into the forming mold and heated and pressed hard, so that the silicone rod is heated and expanded and the ultra-thin plastic film tube is stretched. Embryo formation. [0004] The hockey stick molding method in the prior art has the following shortc...
