Description

Technical Field

[0001] This utility model relates to the field of rubber product manufacturing technology, and in particular to a rubber product punching die device. Background Technology

[0002] Rubber products are widely used in modern industrial production, and their manufacturing processes are crucial. As a key step in the molding of rubber products, the stamping die plays a decisive role in product quality and production efficiency. Rubber products encompass various products made from both natural and synthetic rubber. With the production of synthetic rubber surpassing that of natural rubber, especially styrene-butadiene rubber (SBR), which ranks among the top producers, the scale of rubber product manufacturing continues to expand.

[0003] A typical rubber product stamping die device consists of a pressing device, a die, and a fixing mechanism. The pressing device uses a hydraulic system to firmly clamp the rubber raw material onto the die surface. The die uses the cooperation of the upper and lower dies to form the material under pressure. The fixing mechanism ensures that the die position is fixed during stamping by rigidly connecting the die to the main body of the equipment.

[0004] In the aforementioned technologies, the fixing mechanisms of some devices rely heavily on bolt tightening structures. During installation, the bolt hole positions need to be repeatedly aligned and adjusted, resulting in a long installation time per unit. This is especially problematic when changing molds of different specifications in mass production, where frequent installation operations severely restrict production line switching efficiency. Furthermore, in mold disassembly scenarios, existing fixing structures often deform or rust due to long-term use, making bolt removal difficult and sometimes requiring additional tools for forced disassembly. This not only increases the labor intensity of operators but also easily causes scratches, deformations, and other damage to the mold surface, affecting mold accuracy and service life. Therefore, a rubber product punching die device is proposed to solve the above problems. Utility Model Content

The return spring 13 and the fixed pull rod 14 sleeved on the far side of the pin 12 are used for the reset and displacement operation of the pin 12. After pressing, the air injection port 7 on the inner side of the bottom of the connecting seat 2 injects air into the air base plate 8. The air holes 16 on the air base plate 8 and the bottom mold 15 help the gas flow, which on the one hand regulates the mold temperature, and on the other hand uses the gas pressure to achieve demolding. The slide rail 18 at the bottom of the bottom mold 15 and the slide rail 24 at the top of the top mold 21 are used for the installation and fixation of the bottom mold 15 and the air base plate 8 with the top mold 21 and the lower pressure plate 9, respectively.
