Description

TECHNICAL FIELD

[0001] The utility model relates to injection molding device technical field, specifically a short wire sheath injection molding device. BACKGROUND

[0002] The brake pad warning line is a safety device installed on the brake pad, and its main function is to remind the driver to replace when the brake pad is worn to a certain extent. The brake pad warning line is usually an electronic wire. When the brake pad is worn to a certain extent, the wire will be ground off by the brake disc, causing the circuit to be disconnected, thereby triggering the brake warning light of the vehicle to light up, reminding the driver to replace the brake pad. The end of the previous brake pad warning line is columnar. With the development of technology, the wire with L-shaped end is now commonly used as the warning line, which is more firmly fixed and has a larger wire contact area. However, the production personnel need to bend the end of the wire into an L shape through an auxiliary tool before placing it into the injection molding mold for injection molding. This process is complicated and reduces work efficiency. Secondly, the existing injection molding device needs to be fixed before injection molding, and then the injection molded wire is removed and placed again. During the injection molding process, the operator needs to wait for a long time, which reduces efficiency. Finally, the traditional injection molding mold needs to be pulled out by the operator after injection molding. During the pulling process, the stress point of the product is concentrated, which can easily damage the product, reduce the yield of the product, and increase the production cost. SUMMARY
