Description

Technical Field

[0001] This utility model relates to the field of injection molding production technology, and in particular to a cushion back shaping device. Background Technology

[0002] Currently, in seat design, especially for scenarios requiring prolonged sitting such as offices and driver's cabs, lumbar support cushions have become an important accessory for improving seat comfort and protecting the user's lumbar health.

[0003] The main body of the lumbar support cushion is made of plastic injection molding, and then flexible cushioning materials such as memory foam are added to form the final product. However, after the main body of the lumbar support cushion is removed from the injection molding machine, the temperature difference between the workpiece and room temperature can cause it to shrink and deform, affecting product quality. Therefore, this needs to be improved. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a seat cushion post-shaping device, which can cool and shape the injection-molded seat cushion.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A seat cushion shaping device includes a worktable, a positioning bracket, a backrest positioning assembly, a drive component, and a cooling fan. The seat cushion is placed on the worktable. The positioning bracket is installed on the worktable to fix the base plate of the seat cushion. The backrest positioning assembly includes a mounting bracket and a pressure plate. The mounting bracket is installed on the worktable, and the pressure plate is slidably connected to the mounting bracket. The drive component is installed on the mounting bracket, and the pressure plate is connected to the output end of the drive component. The pressure plate is pressed down to the inner side of the seat backrest. The cooling fan is disposed on the worktable.

[0007] By adopting the above technical solution, the positioning bracket and the backrest positioning component work together to achieve the XYZ three-axis positioning of the seat cushion, and the cooling fan is used for cooling and shaping. This can solve the problem of deformation after injection molding of the seat cushion and improve product quality.

[0008] In one possible implementation, the positioning bracket includes a front positioning plate and an elastic pressure plate. The front positioning plate is mounted to the worktable, and one end of the elastic pressure plate is fixed to the front positioning plate, while the other end can be elastically pressed against the base plate of the seat cushion.

[0009] By adopting the above technical solution, the front positioning plate and the elastic pressure plate are mainly used to position and fix the base plate of the seat cushion.

[0010] In one possible implementation, the worktable is provided with a sliding groove, in which a fixing bolt is slidably installed. The front positioning plate is provided with a mounting hole for the fixing bolt to be installed. The fixing bolt passes through the mounting hole and is locked in place by a nut.

[0011] By adopting the above technical solution, the sliding groove will facilitate the sliding installation of the front positioning plate.

[0012] In one possible implementation, the mounting bracket includes two mounting columns and a mounting plate. The two mounting columns are fixed to the workbench, and the mounting plate is slidably mounted on the two mounting columns. Each of the two mounting columns is provided with a stop hole evenly distributed in the vertical direction. The mounting plate is provided with a positioning hole, and a positioning pin is slidably mounted in the positioning hole. The positioning pin can be inserted and fixed with any one of the stop holes.

[0013] By adopting the above technical solution, the setting of the gear hole facilitates the adjustment of the installation height of the drive component.

[0014] In one possible implementation, the pressure plate is further provided with a rear support member, one end of which is fixedly connected to the pressure plate, and the other end of which abuts against the middle of the back of the seat cushion.

[0015] By adopting the above technical solution, the rear top component further stabilizes the installation position of the seat cushion and also reduces deformation in the middle of the seat back.

[0016] In one possible implementation, the rear support includes a fixing rod and a pressing part, the fixing rod is fixedly connected to the pressing part, the fixing rod is rotatably connected to the pressure plate, and locking nuts are threaded on both sides of the fixing rod.

[0017] By adopting the above technical solution, the setting of the fixing rod and the pressure part will facilitate the adjustment of the pressure on the back of the seat cushion.

[0018] Compared with existing technologies, the advantages of this utility model are:

[0019] 1. The positioning bracket and backrest positioning components work together to achieve XYZ three-axis positioning of the seat cushion. The cooling fan is used for cooling and shaping, which can solve the problem of deformation after injection molding of the seat cushion and improve product quality. Attached Figure Description
