[0002] In the injection molding of automotive safety components such as seat belt accessories, airbag covers, sensors, and controllers, the requirements for product size, consistency, and appearance are extremely high, and the existing production process has obvious shortcomings. Currently, injection molding production uses a semi-automatic method with manual nut installation. This method results in long production cycles, is prone to nut omissions, over-installation, and improper nut placement, leading to a high product scrap rate. These defects can easily flow into the next process, causing production disruptions.

[0003] In existing injection molding production processes, automated production is used. However, due to the constraints of product structure and existing mold control, redeveloping molds and automated equipment is costly, inflexible, and results in limited product variety, making diversified production impossible.

[0005] Based on the above objectives, this utility model provides a controller plastic cover nut installation fixture, including a positioning plate, with mold positioning posts fixed downwards at the four corners of the positioning plate, and a push plate slidingly fitted around the four mold positioning posts. The push plate is located below the positioning plate, and eight nut positioning posts are distributed downwards from the bottom of the positioning plate. The push plate slides around the eight nut positioning posts. Eight guide push tubes are fixedly installed at the bottom of the push plate, and the eight guide push tubes slide around the eight nut positioning posts respectively. Nuts are fitted at the bottom ends of the eight nut positioning posts, and the guide push tubes are located above the nuts. A manual push mechanism is connected to the top of the push plate.

[0006] Preferably, a positioning guide sleeve is provided on the outside of the mold positioning column, and the positioning guide sleeve is fixed on the lower push plate.

[0007] Preferably, the manual push mechanism includes two connecting columns fixedly connected to the top of the push plate. The two connecting columns slide upward through the positioning plate, and the top of the two connecting columns are connected to a push plate. A return spring is provided outside the connecting columns between the positioning plate and the push plate.

[0008] Preferably, the positioning plate is provided with a positioning guide sleeve two at the through-hole of the connecting column, the connecting column slides through the positioning guide sleeve two, the top end of the reset spring is connected to the bottom of the push plate, and the bottom end of the reset spring is connected to the top end of the positioning guide sleeve two.

[0009] Preferably, limit posts are fixedly provided at both ends of the top of the push plate, the limit posts slide upward through the positioning plate, and the top of the limit posts is provided with limit heads.

[0010] Preferably, the positioning plate is provided with a positioning guide sleeve three at the through point of the limiting post, and the limiting post slides and is sleeved in the positioning guide sleeve three.

[0011] Preferably, the bottom periphery of the nut positioning post has a rough, textured surface. The nut is fitted onto the textured surface of the nut positioning post and is pushed off the nut positioning post by the guide tube.

[0012] The beneficial effects of this utility model are as follows: This utility model inserts four mold positioning pins into the positioning holes of the injection mold, and puts eight nuts on the rough surface of the bottom of the eight threaded positioning pins at the bottom of the positioning plate.
