Embodiment 2

[0053] see image 3 The difference from Embodiment 1 is that the auxiliary fixing assembly 25 includes a negative pressure pump 251 arranged inside the base 1, and the suction end of the negative pressure pump 251 is connected to the fixing tube at the lower end of the suction cup 254 through a suction tube 256, so The sliding sleeve on the fixed pipe is provided with a sliding sleeve 253, and the sliding sleeve 253 is connected and fixed with the inner wall of the blanking opening 6 through a positioning rod. Connect and fix by telescopic spring 252;

[0054] The first lower module 7 and the second lower module 10 are provided with adsorption holes 11 corresponding to the suction cups 254;

[0055] During post-processing, when the lower module rotates to the blanking port 6, under the action of the negative pressure pump 251, the upper end of the suction cup 254 will generate an adsorption force, and under the action of the adsorption force, the suction cup 154 ​​will contac...

Abstract

The invention discloses a punching device for processing a disposable food box mould. The punching device comprises a base and support legs arranged on the both sides of the lower end of the base, andthe lower end of each support leg is provided with a support block; a collection box is arranged between the right and left support legs, and the both sides of the collection box are connected with the support legs through locating rods fixedly; a top plate is arranged above the base, and the left lower side of the top plate is connected with the base through a support column fixedly; the base isprovided with a lower mould assembly used for placing a foot box to be machined, and the upper end of the top plate is provided with a lifting hydraulic cylinder; the output end of the lifting hydraulic cylinder is connected with an upper mould assembly corresponding to the lower mould assembly; and the upper mould assembly comprises a horizontal plate connected with the output end of the liftinghydraulic cylinder and arranged horizontally. The punching device is designed for overcoming the shortcomings of an existing device, and switching between drill bits can be achieved, thereby facilitating processing of different holes in a workpiece; the reloading time can be shortened, so that the processing efficiency of the device is improved; and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of injection molding equipment, in particular to a hole opening device for mold processing of a disposable lunch box. Background technique [0002] With the improvement of environmental protection and health requirements year by year, disposable fast food boxes have shifted from foam lunch boxes to environmentally friendly lunch boxes. The original foam lunch boxes were eliminated due to their inability to withstand high temperatures and the damage to the environment caused by the production process. Plastic lunch boxes have been replaced. , paper lunch boxes, wooden lunch boxes, biodegradable lunch boxes and so on. Among them, plastic has the characteristics of low toxicity, high melting point, strong plasticity, easy production and relatively low cost, so it has become the mainstream material for manufacturing disposable lunch boxes. [0003] Plastic disposable lunch boxes generally use PP as the main raw...
