Description

Technical Field

[0001] The utility model relates to the field of underwear processing equipment, in particular to a die cup die pressing and punching device. Background Art

[0002] The die cup is one of the important components of underwear. In order to ensure breathability, the existing die cups usually have holes punched in them. The die pressing and punching of the existing die cups are usually carried out separately. If the holes are punched first and then die pressed, it is possible that the breathable holes left by punching will be deformed and blocked during die pressing, resulting in weakened or even lost breathability; if die pressing is carried out first and then punching, then the die cup will be locally extruded during punching, which may cause the die cup to deform. In addition, the die cup has a certain curvature after die pressing, and it is difficult to accurately control the punching position during punching. Summary of the Invention

[0003] The utility model mainly solves the above problems and provides a die cup die pressing and punching device capable of performing die pressing and punching simultaneously.

The lower template is fixedly arranged on the frame body and is located directly below the upper template. A forming groove matching the forming punch is arranged on the lower template. The punching mechanism is arranged at the corresponding position of the punch on the top of the frame body. Through holes for the punching mechanism to pass through are arranged on the upper template, the forming punch and the lower template.

[0005] As a preferred scheme of the above scheme, the punching mechanism includes a second power cylinder, a mounting plate and a plurality of punching heads. The second power cylinder is fixedly arranged on the top of the frame body. The mounting plate is fixedly arranged on the piston rod of the second power cylinder. The punching heads are fixedly arranged on the mounting plate.

[0006] As a preferred scheme of the above scheme, a connecting edge is arranged at the corresponding position of the forming die on the lower side surface of the lower template, and a debris box is arranged on the connecting edge.

[0007] As a preferred scheme of the above scheme, the connecting edge is circular, a first thread is arranged on the outer side wall of the connecting edge, and a second thread matching the first thread is arranged on the inner wall of the opening of the debris box.

[0008] As a preferred scheme of the above scheme, the length of the punching head is greater than the total thickness after the upper template and the lower template are closed.

[0009] The advantages of the present utility model are as follows: Molding and punching are carried out simultaneously, which can avoid the blockage of through holes formed by punching and the deformation of the mold cup, and the positions of the punched ventilation holes are accurate; a debris box is provided to collect the debris generated by punching.

[0015] The technical solution of the present utility model will be further described below through embodiments in conjunction with the drawings.

[0016] Embodiment:

[0017] A mold cup molding and punching device in this embodiment, as Figure 1 and Figure 2 shown, includes a frame body 1, an upper template 3, a lower template 2, a punching mechanism and a plurality of first power cylinders 4. The first power cylinders 4 are fixedly arranged at the top of the frame body 1. In this embodiment, there are three first power cylinders 4, and the piston rods of the three first power cylinders 4 are respectively fixed to both ends and the middle of the upper template 3. Two forming convex dies 11 are symmetrically arranged on the lower side surface of the upper template. The lower template 2 is fixedly arranged on the frame body 1 and is located directly below the upper template 2. A forming groove 9 matching the forming convex die 11 is provided on the lower template 2. The punching mechanism is arranged at the top of the frame body corresponding to the convex die. The punching mechanism includes a second power cylinder 5, a mounting plate 6 and a plurality of punching heads 10. There are two second power cylinders 5, which are respectively fixedly arranged at the top of the frame body and are located directly above the forming convex die. The mounting plate is fixedly arranged on the piston rod of the second power cylinder 5, and the punching heads 6 are fixedly arranged on the mounting plate. The length of the punching head is greater than the total thickness after the upper template and the lower template are closed. Through holes 12 for the punching mechanism to pass through are provided on the upper template 3, the forming convex die 11 and the lower template 2. A connecting edge 7 is provided on the lower side surface of the lower template 2 corresponding to the forming concave die, and a debris box 8 is arranged on the connecting edge. The through hole 12 is communicated with the debris box.

[0018] In this embodiment, the connecting edge 7 is circular, a first thread is provided on the outer side wall of the connecting edge 7, and a second thread matching the first thread is provided on the inner wall of the opening of the debris box 8. The debris box is fixed to the connecting edge through the first thread and the second thread.

[0019] In this embodiment, the working process of the cup mold pressing and punching device is as follows. Initially, as Figure 1 shown, the upper template is separated from the lower template, and the punching head is located in the through holes of the upper template and the forming punch but does not protrude from the forming punch; after the cup is placed into the forming female mold, mold pressing is performed. As Figure 3 shown, the first power cylinder drives the upper template to press down, so that the forming punch extends into the forming female mold to perform mold pressing on the cup 13. During this process, the second power cylinder extends synchronously with the first power cylinder and has the same elongation; then punching is performed. As Figure 4 shown, the first power cylinder remains in its original state, the second power cylinder extends, so that the punching head protrudes from the forming female mold and punches the cup. After punching, the debris generated by punching is continuously pushed into the debris box. Subsequently, the punching head retracts. After the punching head retracts into the forming punch, the upper template also retracts, completing the mold pressing and punching of the cup.

[0020] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
