Description

Technical Field

[0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a molding device for processing a car seat back panel. Background Art

[0002] Car seats are seats for people to sit in a car. They can be roughly divided into front seats and rear seats according to their parts, including headrests, backrests, cushions, armrests, etc. Car seat backs are the mounting plates required for the car seat back frame. While playing a role in aesthetics, they also determine the comfort and stability of the car seat. Therefore, car seat backs are essential for car seats.

[0003] At present, the most common and mature processing method for seat back panels is injection molding, that is, the lower mold base and the upper mold base with corresponding cavities are installed, and the fluid material is injected into the cavity from the injection port after the mold is closed, and then cooled to form, which is convenient and fast;

[0004] However, the following problems were found during use:

[0005] 1. The natural cooling speed of the cavity is slow, which affects the production efficiency;

[0006] 2. Because the formed back panels are mostly irregular in shape and there is spatial interference with the forming device, it is difficult for the robot to enter the working space of the forming device and to grab the back panel. Furthermore, the robot is prone to problems such as pinch marks when grabbing the back panel. Therefore, the current method of unloading the formed back panel is manual unloading, which is a waste of manpower. Summary of the invention

The lifting adjustment mechanism 4 is installed with a telescopic cylinder 5, and the output ends of the telescopic cylinders 5 on the left and right sides are connected to a guide mechanism 6, and the output end of the telescopic cylinder 5 on the rear side is connected to a push strip 7;

[0039] The base 1 is provided with a lower mold base 8, the lower mold base 8 is located on the upper side of the cavity 2, the lower mold base 8 is provided with a cavity 9, the lower mold base 8 is provided with a cooling cavity 10 at the lower side of the cavity 9, the cooling cavity 10 is provided with a water inlet 11 and a water return port 12, and the cavity 9 is provided with an injection port 13;

[0040] The base 1 is provided with guide rods 14 at the four corners, and a lifting plate 15 is slidably installed on the four guide rods 14, and an upper die seat 16 matching the specifications of the lower die seat 8 is installed on the lifting plate 15, and a top plate 17 is installed on the top of the four guide rods 14, and a hydraulic cylinder 18 is installed on the top plate 17, and the output end of the hydraulic cylinder 18 is connected to the center of the upper die seat 16;

[0041] The lower die base 8 is provided with rectangular grooves 19 on both sides of the cavity 9, and a push rod 20 is slidably installed in the rectangular groove 19. The lower end of the push rod 20 is located in the cavity 2, and a lifting plate 21 is installed at the lower end of the push rod 20. A base plate 22 is installed inside the cavity 2, and an electric telescopic cylinder 24 is installed at the center of the bottom of the cavity 2.

[0043] In this embodiment, when a molding device for processing a car seat back panel is used, after the corresponding lower mold base 8 and upper mold base 16 are installed, the hydraulic cylinder 18 is controlled to operate, driving the lifting plate 15 to descend, so that the upper mold base 16 and the lower mold base 8 are molded together, and then injection molding is performed into the mold cavity 9 through the injection port 13. The degassing port and other structures in the injection molding process are common technologies of the injection molding process and are not described in detail.

[0044] After the injection molding is completed, under the effect of the rectangular groove 19 and the position of the top of the push rod 20 limited by the electric telescopic cylinder 24, two rectangular ear plates will be formed on both sides of the finished back plate. When the injection molding is completed, the upper mold base 16 leaves, and the electric telescopic cylinder 24 runs to drive the push rod 20 to rise, lift the ear plate, and complete the demoulding of the finished product in the cavity 9;

[0049] Preferably, the length of the push bar 7 is equal to the distance between the left and right rectangular grooves 19. Such a design ensures that the material in the rectangular groove 19 can be pushed. In fact, the length of the push bar 7 can also be considered according to specific circumstances.

[0050] Preferably, a linear bearing is installed at the sliding matching position of the lifting plate 15 and the guide rod 14.
