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:
The present invention relates to plastic cement products mouth of a river technical field of processing equipment, refer in particular to plastic cement products soft or hard glue mouth secondary punch equipment.
Background technology:
Along with the application of organic material in people's daily life is more and more, plastic material conduct organic material commonly used, extensive use in people's life.Plastic cement products commonly used adopts Shooting Technique to make usually, when injection moulding, glue-feeder on the product is the mouth of a river alleged in the industry, in order to guarantee product effectively depanning in design, and eject smooth and easyly during depanning, usually, so just produce a problem guaranteeing that the mode that adopts a plurality of glue-feeders to advance glue simultaneously under the indeformable prerequisite of product makes, promptly be can cause the mouth of a river more on product structure design in the formed product process, common product be several caves of mould types.After the formed product, the mouth of a river need be removed, at present during the converted products mouth of a river, the way that adopts is manually to cut, cut with blade with cutting nippers usually, or uses the die cutting device automatic cutting.
The die cutting device at the existing processing plastic product mouth of a river generally comprises die cutting die and drives the drive unit of die cutting die action, die cutting die comprises the upper die and lower die that cooperatively interact, have the hole, the mouth of a river that matches with product mouth of a river shape corresponding to position, the product mouth of a river on the counterdie, be interconnected by guide groove between each hole, mouth of a river, be installed with mouth of a river hole shape matches corresponding to hole site, the mouth of a river on the patrix and dash pin, utilize this die cutting device can disposablely cut a plurality of mouths of a river.During with the simultaneously die-cut soft or hard glue mouth of existing plastic cement products mouth of a river die cutting device, because the washing shrinkage difference when ebonite runner and the moulding of flexible glue runner is very big, this makes that the position dimension at each mouth of a river of each product is very inaccurate on this series products mould bases, this has caused the die-cut product that comes out all to have the high phenomenon of the cut wound and the residual mouth of a river, die-cut weak effect, thereby, existing plastic cement products mouth of a river die cutting device can not be used for the die-cut plastic cement products that has soft or hard glue mouth simultaneously, so having the plastic cement products of soft or hard glue mouth generally all is to cut away the mouth of a river by artificial, waste of manpower, production efficiency is low, the production cost height.
Summary of the invention:
Purpose of the present invention be exactly the deficiency that exists at prior art and provide that a kind of soft or hard glue mouth plastic cement products is die-cut at twice, the ebonite mouth of a river and the accurate positioning of the flexible glue mouth of a river, die-cut effective plastic cement products soft or hard glue mouth secondary punch equipment.
