Problems solved by technology
[0002] In the various processes of manufacturing rubber tires, various semi-finished rubber parts need to be pasted together. During the lamination process of each layer of film, air bubbles are inevitably trapped between the film layers, which greatly affects the quality of the rubber tire. Quality, in order to avoid the above problems, some units adopt the method of manually punching holes on the film, which cannot ensure the reasonable distribution of the vent holes, and the work efficiency is low; some units use the rolling method, which will cause a certain degree of damage to the film surface The damage of the exhaust hole is poor; some units adopt the single-row puncture method, the cylinder drives the needle template, and a single row of punching needles is installed on the needle template. holes, the quality of the vent holes obtained with this equipment is poor, and the production efficiency is low

The film punching device includes floating frame, horizontal block, vertical block, demoulding cylinder, lower mold plate with pin slots, pin mold plate with several rows of punching pins, and demoulding plate with guide holes corresponding to the pin slots in the lower mold plate and punching pins in the pin mold plate. The film punching and demoulding process with the device includes the following steps: 1. depressing the demoulding plate and the pin mold plate to make the demoulding plate contact the film; 2. further moving the pin mold plate downwards to punch while maintaining the demoulding plate immobile; 3. moving the pin mold plate upwards to withdraw the punching pins while maintaining the demoulding plate immobile; and 4. moving the pin mold plate and the demoulding plate upwards simultaneously to separate from the film. The present invention has reasonable structure, high punching quality and high production efficiency.
