Problems solved by technology

[0002] In the production process of optical light guide film, thin film button and other products, multiple processing procedures are often required. Cutting and punching processing for light guide film and thin film button is a common process, but at present, most molds are punched for The disposal of the washed waste is not in place, and many of them use the method of manually removing the waste. This method is inefficient, high in cost and low in product yield.

Abstract

The invention relates to the technical field of dies, in particular to a combined die of a punching die and a cutting die. The combined die comprises an upper die mechanism, a lower die mechanism anda discharging mechanism. The upper die mechanism comprises an upper die plate, a clamping plate and a stripping plate, wherein a plurality of elastic parts are arranged between the clamping plate andthe stripping plate, the clamping plate is provided with a plurality of punch bits, and the stripping plate is provided with the cutting die for punching product shapes. The lower die mechanism comprises a lower die plate and a concave plate. The discharging mechanism comprises rotating rods, forward and reverse rotation motors, sensing assemblies, suckers and discharging holes formed in the lowerdie mechanism, wherein the rotating rods are arranged inside the punch bits, the forward and reverse rotation motor are connected with the rotating rods in a driving mode, the discharging holes are used for allowing waste generated after punching of the punch bits to pass through, the suckers are used for sucking waste in the discharging holes, and the sensing assemblies are used for sensing whether waste falls off the discharging holes. By means of the combined die, the waste generated after hole punching can be removed automatically instead of manually, and thus the operation efficiency isimproved.

Description

technical field [0001] The invention relates to the technical field of dies, in particular to a combined die of a punching die and a cutting die. Background technique [0002] In the production process of optical light guide film, thin film button and other products, multiple processing procedures are often required.
