Automatic injection-molding part runner cutting equipment

Abstract

The invention relates to the technical field of cutting of injection-molding parts, in particular to automatic injection-molding part runner cutting equipment which comprises an upper die and a lower die. The upper die is driven to moving up and down by a first cylinder, and the lower die is matched with the upper die. The upper die comprises a clamp plate and a cutting blade arranged under the clamp plate; the lower die comprises a bottom plate and a bottom punch which is fixedly connected to the bottom plate and used for fixing an injection-molding part; the shape of the cutting blade is matched with the profile of a to-be-cut portion of the injection-molding part. With the matching structure of the upper die and the lower die, the upper die is driven to move from bottom to top to cut along the profile of the to-be-cut portion of the injection-molding part under driving of the first cylinder, so that the runner portion of the injection-molding part is peeled off completely at one step; the process of separating runners by the cutting blade under driving of the first cylinder substitutes for the process of manual separation of runners, contact between the cutting blade and the hands is avoided during the whole operating process so that workers' hands are protected; besides, the equipment is easy and convenient to operate and reduces labor intensity of workers.

Description

technical field [0001] The invention relates to the technical field of cutting injection molding parts, in particular to an automatic water cutting device for injection molding parts. Background technique [0002] Injection molded parts refer to various injection molded products produced by injection molding machines, collectively referred to as injection molded parts, including various packaging, parts, etc. It is mainly made of materials such as polyethylene or polypropylene with various organic solvents added. After the plastic is plasticized in the heating barrel of the injection molding machine, it is injected into the cavity of the closed mold by the plunger or the reciprocating screw to form the plastic processing method of the product. This method can process products with complex shapes, precise dimensions or inserts, and has high production efficiency. Most thermoplastics and some thermosetting plastics (such as phenolic plastics) can be processed by this method....

AI Technical Summary

Problems solved by technology

In the injection molding workshop of the prior art, the runners are generally cut off manually with scissors, and each injection molded part needs to be cut many times, which is time-consuming, labor-intensive, and inefficient

[0004] Taking the rice cooker switch button as an example, each injection molded part is injected with 16 switch parts at one time, and the normal separation of the nozzle needs to be cut 16 times, and because the nozzle is large, it needs to be flattened with a knife after cutting, and the cutting and knife batch process It is easy to scratch the workpiece and hurt the hand, the efficiency is low, and the defect rate is high
