Secondary punching equipment for hard and soft rubber inlets of plastic product

Abstract

The invention relates to the technical field of machining equipment for rubber inlets of plastic products, in particular to secondary punching equipment for hard and soft rubber inlets of a plastic product. The equipment comprises a base, a lower die, an upper die and a driving device, wherein a hard rubber punching bottom die and a soft rubber punching bottom die are arranged on the lower die; more than one rubber inlet hole is formed in the hard rubber punching bottom die; more than one blanking hole is formed in the soft rubber punching bottom die; lower cutters are arranged at the periphery of the rubber inlet hole and the blanking hole; and the upper die is fixedly provided with upper cutters. By the equipment, the hard and soft rubber inlets of the product are punched for two times, so that the hard rubber inlet and the soft rubber inlet of the product which are opposite to each other can be extremely accurately positioned by a jig lower die, the phenomena of cut wounds and high residual rubber inlets can be prevented by a punched product, and the equipment has a good punching effect; when the soft rubber inlet is punched, the hard rubber inlet of the next plastic product can be punched in the hard rubber punching bottom die simultaneously; and a product in a mold can be machined well when the upper die punches downwards every time, so that the equipment has high production efficiency, saves labor and reduces production cost.

Description

Technical field: [0001] The invention relates to the technical field of processing equipment for nozzles of plastic products, in particular to secondary punching equipment for nozzles of hard and soft plastic products. Background technique: [0002] With the increasing application of organic materials in people's daily life, plastic materials, as commonly used organic materials, have been widely used in people's lives. Commonly used plastic products are usually made by injection molding process. During injection molding, the plastic inlet on the product is called the nozzle in the industry. In order to ensure that the product can be effectively released from the mold in design, and the ejection is smooth when the mold is released, Usually, under the premise of ensuring that the product does not deform, it is manufactured by using multiple glue inlets to feed glue at the same time. This will cause a problem, that is, there will be more nozzles in the product structure design ...

AI Technical Summary

Problems solved by technology

When the existing nozzle punching equipment for plastic products is used to punch the soft and hard glue nozzles at the same time, due to the large difference in shrinkage rate when the hard rubber runner and the soft rubber runner are formed, this makes each product on the mold base of this type of product The position and size of the nozzle is very inaccurate, which leads to the phenomenon of cuts and high residual nozzle in the punched products, and the punching effect is poor. Therefore, the existing nozzle punching equipment for plastic products cannot be used for punching and cutting simultaneously. Plastic products with soft and hard glue nozzles, so plastic products with soft and hard glue nozzles are generally cut off by manual processing, which wastes manpower, low production efficiency, and high production costs
