Problems solved by technology
[0002] The plastic cover or plastic container is thermoformed by plastic sheet, and punched after forming. In the existing punching die, the punching upper die is fixedly set, and the punching lower die is raised and lowered. The punching upper die and the punching lower die cooperate with each other. Punching, resulting in the molding of the plastic sheet can only be conveyed downwards, through the lifting of the punching lower die to give way, which leads to the limitations of plastic sheet forming and conveying, and can only be formed downwards. Unable to meet the upward bulge or the simultaneous formation of bulge upward and downward, which makes the product produced single and the utilization rate of the plastic sheet is low

Embodiment Construction
[0016] Accompanying drawing has shown structure of the present invention, further illustrates its relevant details below again in conjunction with accompanying drawing. The plastic cover or plastic container punching mechanism includes a mold frame 1, a punching upper die 2, a punching lower die 3 and a traction device 4. The traction device 4 is a traction roller group, and the traction device 4 is arranged on the mold frame 1, the plastic sheet is pulled and conveyed, and the punching upper die 2 and the punching lower die 3 are respectively provided with corresponding punches 21 and punching openings 31, and the punching openings 31 have a certain depth so that the punching openings 31 A number of plastic covers or plastic containers can be clamped and stacked inside. The punching upper die 2 and the punching lower die 3 can be relatively moved and arranged on the guide column 11 of the mold frame 1, and the punching upper die 2 is driven by the upper driving device 5 Drivi...

The invention discloses a plastic cap or plastic container punching mechanism. The plastic cap or plastic container punching mechanism comprises a mould base, a punching upper die, a punching lower die and a traction device. The punching upper die and the punching lower die are correspondingly provided with a punch and a punching port. The plastic cap or plastic container punching mechanism is characterized in that the punching upper die and the punching lower die can be relatively moveably installed on a guide column of the mould base, the punching upper die is driven to be ascended and descended by an upper driving device, the punching lower die is driven to be ascended and descended by a lower driving device, and a finished product conveying device is installed below the punching lowerdie. The plastic cap or plastic container punching mechanism is rational in structure, convenient for punching, and suitable for punching a double-faced convex-formed plastic sheet.
Description
technical field [0001] The invention relates to an improved invention of a punching mechanism, in particular to an improved invention of a plastic cover or plastic container punching mechanism. Background technique [0002] The plastic cover or plastic container is thermoformed by plastic sheet, and punched after forming. In the existing punching die, the punching upper die is fixedly set, and the punching lower die is raised and lowered. The punching upper die and the punching lower die cooperate with each other. Punching, resulting in the molding of the plastic sheet can only be conveyed downwards, through the lifting of the punching die to give way, which leads to the limitations of plastic sheet forming and conveying, and can only be formed downwards. It is impossible to meet the requirements of upward bulge or simultaneous formation of bulge upward and downward, so that the manufactured product is single and the utilization rate of the plastic sheet is low.
