At the same time, the use of an air guide tube to act on the material guide tube is also likely to cause deformation of the upper surface of the workpiece, thereby causing the injection molding of the workpiece to fail. In view of the above problems, we propose a stamping injection mold. Summary of the invention

[0004] The purpose of the present invention is to address the deficiencies of the prior art and provide a stamping injection mold, which solves the problem that when the existing injection mold is compression-molding the material, the upper and lower surfaces of the plastic workpiece are heated unevenly during demolding, which increases the difficulty of demolding. At the same time, the use of an air guide tube to act on the material guide tube can easily cause deformation of the upper surface of the workpiece.

[0005] When the existing injection mold is compression molding the material, since the material is injected from the compression molding plate, the upper and lower surfaces of the plastic workpiece are heated unevenly during demoulding, which makes demoulding more difficult. At the same time, the use of an air guide tube to act on the material guide tube is also likely to cause deformation of the upper surface of the workpiece, thereby causing the injection molding of the workpiece to fail.

The stamping drive mechanism includes a stamping cylinder, a stamping slide fixedly connected to the stamping cylinder, a mold base connecting rod, and a linkage fixing part. During operation, the stamping cylinder is controlled to start, so that the stamping cylinder drives the stamping slider, the die base connecting rod and the upper die base to move, and the upper die base contacts with the lower die base to form an injection cavity, and then the hot melt material to be formed is injected into the upper die base. After the injection is completed, the stamping cylinder is continued to be controlled to start, so that the stamping cylinder pushes the upper die base and the lower die base to move downward relative to the punching seat. At this time, the punching seat punches the formed plastic workpiece. At the same time, when the stamping slider moves, it can also drive the linkage fixing part and the auxiliary demoulding component to move, so that the auxiliary demoulding component fixes the lower die base, and then the plastic workpiece is separated from the upper die base to complete the auxiliary demoulding operation.

[0081] When the existing injection mold is compression molding the material, since the material is injected from the compression molding plate, the upper and lower surfaces of the plastic workpiece are heated unevenly during demoulding, which makes demoulding more difficult. At the same time, the use of an air guide tube to act on the material guide tube can easily cause deformation of the upper surface of the workpiece, thereby causing the injection molding of the workpiece to fail. In view of the above problems, we have proposed a stamping injection mold. In short, the stamping injection mold includes an equipment base 1, an injection mold assembly 2, and a stamping drive mechanism 3, and the injection mold assembly 2 includes an upper mold base 21, a lower mold base 22, and a punching base 23. The stamping drive mechanism 3 includes a stamping cylinder 31, a stamping slide block 32 fixedly connected to the stamping cylinder 31, a mold base connecting rod 35, and a linkage fixing portion 34. During operation, the stamping cylinder 31 is controlled to start, so that the stamping cylinder 31 drives the stamping slide 32, the die base connecting rod 35 and the upper die base 21 to move, and the upper die base 21 contacts with the lower die base 22 to form an injection cavity, and then the hot-melt material to be formed is injected into the upper die base 21. After the injection is completed, the stamping cylinder 31 is continued to be controlled to start, so that the stamping cylinder 31 pushes the upper die base 21 and the lower die base 22 to move downward relative to the punching seat 23. At this time, the punching seat 23 punches the formed plastic workpiece. At the same time, when the stamping slide 32 moves, it can also drive the linkage fixing part 34 and the auxiliary demolding component 4 to move, so that the auxiliary demolding component 4 fixes the lower die base 22, thereby separating the plastic workpiece from the upper die base 21, and completing the auxiliary demolding operation. In the embodiment of the present invention, a stamping drive mechanism 3 is provided. The linkage fixing part 34 in the stamping drive mechanism 3 is driven by the stamping cylinder 31 and can synchronously drive the auxiliary demoulding component 4 to lock the lower die base 22, so that the auxiliary demoulding operation can be quickly completed after the stamping of the plastic workpiece is completed. At the same time, the auxiliary demoulding component 4 can also act on the lower die base 22, so that the plastic workpiece in the lower die base 22 is quickly cooled and separated from the lower die base 22, thereby improving the success rate of injection molding and stamping of the plastic workpiece.

After the injection is completed, the stamping cylinder 31 is continued to be controlled to start, so that the stamping cylinder 31 pushes the upper mold base 21 and the lower mold base 22 to move downward relative to the punching seat 23. At this time, the punching seat 23 punches the formed plastic workpiece. At the same time, when the stamping slide 32 moves, it can also drive the linkage fixing part 34 and the auxiliary demolding component 4 to move, so that the auxiliary demolding component 4 fixes the lower mold base 22, thereby making the plastic workpiece separate from the upper mold base 21, and completing the auxiliary demolding operation.

[0147] In the embodiment of the present invention, a stamping drive mechanism 3 is provided. The linkage fixing part 34 in the stamping drive mechanism 3 is driven by the stamping cylinder 31 and can synchronously drive the auxiliary demoulding component 4 to lock the lower die base 22, so that the auxiliary demoulding operation can be quickly completed after the stamping of the plastic workpiece is completed.
