Problems solved by technology

[0003] The shell material is attached to the outer wall of the airbag, and there is a gap between the shell materials. Therefore, during the thermosetting molding process, the resin in the shell material changes from solid to liquid, and small air bubbles will appear in the resin. If these small air bubbles are not effectively removed Will lead to a decrease in the quality of the helmet after thermosetting molding
Small air bubbles destroy the internal structure of the composite material, and stress accumulation is prone to occur at the small air bubbles affected by the impact, resulting in tearing of the internal structure and cracks on the whole, affecting the impact resistance of the helmet

Embodiment 1

[0039] refer to figure 1 , is a vacuum autoclave disclosed in the present invention for the production of motorcycle helmets, comprising an autoclave body 1 and a molding device 10, one end of the autoclave body 1 is fixedly connected with a closure 2; the closure 2 is provided with Heating device 20 (label image 3 ); the other end of the autoclave body 1 is connected with a tank door 3; the autoclave body 1 is connected with a vacuum device 4 communicating with the molding device 10; Device 50 , pressure gauge 52 , safety valve 53 and air intake pipe 51 ; air intake pipe 51 communicates with air intake device 5 .

[0040] refer to figure 2 and image 3 , the forming device 10 includes a vacuum bag 101, preferably a PE bag. A forming mold 102 is arranged inside the vacuum bag 101 ; The vacuum device 4 includes a plurality of connection pipes 41 fixedly connected to the outer wall of the autoclave body 1; one end of the connection pipes 41 communicates with a vacuum tub...

Embodiment 2

[0047] Step 1. Preliminary operation of the forming device 10: the inner wall of the forming mold 102 is attached with composite materials and auxiliary materials; and then the inner and outer surfaces of the forming mold 102 are covered with high-temperature vacuum diversion cotton, and then put into the vacuum bag 101.

[0048] Step 2, vacuuming operation: first put the molding device 10 into the autoclave body 1 and at the same time confirm that the gas storage tank 43 is in a normal working state; then connect the joint 103 with the vacuum tube 42; finally open the control valve 44 to start vacuuming, Finally, observe the indication of the air pressure display device 46. If the indication of the vacuum degree is abnormal, close the corresponding control valve 44, and judge that the quality of the outer casing in the forming mold 102 is not up to standard.

[0049] Step 3, thermosetting molding: turn on the electric heater 23 and simultaneously turn on the driving motor 21 t...

Abstract

The invention relates to a vacuum autoclave used for motorcycle helmet production and a motorcycle helmet forming process. The vacuum autoclave comprises an autoclave body and a forming device. The forming device comprises a vacuum bag, a forming mould arranged in the vacuum bag, and a connector connected to the vacuum bag and communicating with the forming mould. One end of the autoclave body isfixedly connected with a closed component. A heating device is arranged in the closed component. The other end of the autoclave body is connected with an autoclave door. The autoclave body is connected with a vacuumizing device used for communicating with the connector. A gas exhausting device and a gas inlet pipe are arranged on the outer wall of the autoclave body in the length direction of theautoclave body in sequence. The gas inlet pipe communicates with a gas inlet device. By means of the vacuum autoclave used for motorcycle helmet production and the motorcycle helmet forming process, the impact strength of a motorcycle helmet is effectively improved, the product quality is improved, and the problem that the impact strength of a motorcycle helmet is low is solved.

Description

technical field [0001] The invention relates to the technical field of helmet production, in particular to a vacuum autoclave used for motorcycle helmet production and a motorcycle helmet molding process. Background technique [0002] A motorcycle helmet is an essential safety equipment for driving a motorcycle, which is used to protect the head and protect against wind and cold. Currently, refer to Figure 8 The equipment for motorcycle helmet production includes equipment book 6, a heating device 61 arranged on the equipment body, a mold 62 arranged in the equipment body, an air bag 63 for covering the shell material and an inflatable air bag arranged in the equipment body are arranged in the mold. device64. During the production of motorcycle helmets, the airbag 63 pasted with the shell material is placed in the mold 62; the inflator 64 is connected to the mold 62 to form a seal and pressurizes the inside of the airbag 63 so that the shell material of the outer wall is c...
