[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In the utility model, through the set demoulding unit and auxiliary unit, when it is necessary to demould the automobile cover, the air pump works, and the generated gas is input into the lower mold box through the air supply pipe, and the generated gas lifts up a gap between the cover and the lower mold box, and then drives the motor to drive the threaded shaft to rotate. Since the threaded shaft is provided with threads with opposite rotation directions at both ends, the two moving parts are close to each other, and the lifting seat is driven by the connecting part to lift the demoulding template, so that the demoulding template pushes out the cover in the lower mold box, thereby realizing convenient demoulding of the automobile cover after molding, and improving work efficiency; when the automobile cover is being molded, the punching pressure can be detected in real time by the pressure sensor, and displayed in real time by the pressure gauge. At this time, the punching pressure of the stamping part can be adjusted in real time by adjusting the pressure regulator and the PLC controller to prevent the finished product effect of the automobile cover from being affected by excessive pressure or too low pressure, thereby improving the yield rate.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods. Example

[0028] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, a car cover forming die with a pressure regulating device comprises a main unit 1, a demoulding unit 2 and an auxiliary unit 4 arranged in the main unit 1, and a pressure regulating unit 3 arranged on the surface of the demoulding unit 2;

[0029] like Figure 3 As shown, the demoulding unit 2 includes a threaded shaft 201 movably arranged inside the main unit 1 and provided with threads at both ends in opposite directions, a lower mold box 207 installed on the inner bottom wall of the main unit 1, a moving part 202 installed on the side surface of the threaded shaft 201, a driving motor 203 installed at the input end of the threaded shaft 201, a lifting seat 204 movably arranged inside the main unit 1, a connecting part 205 arranged between the moving part 202 and the lifting seat 204, and a demoulding plate 206 installed on the top of the lifting seat 204 and movably arranged in the lower mold box 207. When the driving motor 203 drives the threaded shaft 201 to rotate, the moving part 202 can move along the threaded shaft 201.

[0030] like Figure 4 As shown, the auxiliary unit 4 includes an air pump 401 installed on the side wall of the main unit 1, and an air pipe 402 installed at the input end of the air pump 401 and arranged in the lower mold box 207. The setting of the air pipe 402 can transport the gas produced by the air pump 401.

[0031] like Figure 1 As shown, the main unit 1 includes a base box 101, a gantry 102 installed on the top of the base box 101, and a stamping part 103 arranged in the gantry 102. The arrangement of the stamping part 103 is the main tool for stamping and forming the automobile cover.

[0032] like Figure 4 As shown, the stamping part 103 includes a hydraulic cylinder 1031 installed on the inner top wall of the gantry 102, and an upper mold 1032 installed on the telescopic end of the hydraulic cylinder 1031. When the hydraulic cylinder 1031 is telescoped, the upper mold 1032 will move up and down synchronously with it.

[0033] like Figure 3As shown, the connecting member 205 includes a bottom connecting seat 2051 installed on the top of the moving member 202, a top connecting seat 2053 installed on the bottom of the lifting seat 204, and a connecting rod 2052 which is movably connected to the bottom connecting seat 2051 at one end and movably connected to the top connecting seat 2053 at the other end. The setting of the connecting rod 2052 can convert the lateral movement of the bottom connecting seat 2051 into the up and down movement of the top connecting seat 2053.

[0034] like Figure 3 As shown, the demolding unit 2 also includes a limiting washer 208 installed on the inner wall of the base box 101, and the limiting washer 208 is sleeved on the peripheral side of the threaded shaft 201. The setting of the limiting washer 208 prevents the moving part 202 from contacting and colliding with the inner wall of the base box 101 during the movement of the threaded shaft 201.

[0035] When the automobile cover needs to be demolded, the air pump 401 starts working, and the generated gas is input into the lower mold box 207 through the air pipe 402. The generated gas lifts up a gap between the cover and the lower mold box 207, and then drives the motor 203 to drive the threaded shaft 201 to rotate. Since the threaded shaft 201 is provided with threads with opposite rotation directions at both ends, the two moving parts 202 are close to each other, and the lifting seat 204 is driven by the connecting part 205 to lift the demolding plate 206, so that the demolding plate 206 pushes out the cover in the lower mold box 207, thereby realizing convenient demolding of the automobile cover after molding and improving work efficiency.
