[0002] In the process of forming the inward convex surface of the tube fittings of the automobile seat, the traditional method is to form a convex surface by striking. However, the convex surface formed by striking is prone to quality problems such as tilting and unevenness. In addition, the force arm of the striking forming is too long, which can easily cause the tube fittings to break, resulting in a low production yield. Utility Model Content

[0003] In view of the defects existing in the above-mentioned prior art, the technical problem to be solved by the utility model is to provide an inward convex surface forming mold for automobile seat pipes which can improve the forming quality and the yield rate.

[0004] In order to solve the above technical problems, the utility model provides a mold for forming an inward convex surface of a car seat tube, which is characterized by comprising an upper base plate, a lower base plate, and an insert;

[0005] The lower base plate is fixed with one vertical outer guide column on the left and one vertical outer guide sleeve on the right, and the upper ends of the two outer guide columns are respectively inserted into the two outer guide sleeves in a sliding fit manner;

[0006] An upper cavity block is fixed at the lower end of the upper base plate, a lower fixed plate is fixed at the upper end of the lower base plate, a lower cavity block that can slide up and down is provided at the front of the lower fixed plate, an insert fixing seat is fixed at the rear of the lower fixed plate, and a left and right forming limit block for guiding the lower cavity block to slide up and down is fixed on the lower fixed plate, an elastic component is provided at the lower end of the lower cavity block, the upper end of the elastic component abuts against the lower cavity block, and the lower end of the elastic component abuts against the lower fixed plate, and the cavities of the upper cavity block and the lower cavity block face each other vertically;

[0007] The lower cavity block is provided with a left and right sliding guide groove, and the two forming limit blocks are respectively inserted into the two sliding guide grooves on the lower cavity block in a sliding matching manner; the upper cavity block is provided with a left and right forming limit groove open downward, and the upper cavity block can move downward to the top groove walls of the two forming limit grooves to respectively abut against the upper ends of the two forming limit blocks;

[0008] The lower cavity block is provided with an inner guide slot hole on the left and right, and the upper cavity block is fixed with an inner guide column on the left and right, and the two inner guide columns extend into the two inner guide slot holes respectively in a sliding fit manner;

[0009] The insert fixing seat is provided with an insert clamping hole, the rear end of the insert is detachably fixed in the insert clamping hole, and the insert is located directly above the cavity of the lower cavity block, and the upper end of the insert is fixed with a convex pipe molding insert protruding upward.

[0010] The utility model provides a die for forming an inward convex surface of a car seat pipe. Since the lower cavity block is mounted on a lower fixed plate by an elastic component, the elastic component acts as a buffer on the downward pressure of the upper cavity block during convex surface forming, and the convex surface of the workpiece is formed by extrusion. Compared with the existing impact-type convex surface forming method, the die has the characteristics of smooth forming, which can improve the forming quality and yield rate.
