Abstract
An automatic nozzle cutting device comprises an ejector pin face plate arranged on an ejector pin bottom plate, a rear mold plate located above the ejector pin face plate and a rear mold core arranged on the rear mold plate. The rear mold core is provided with a main runner and a cavity, the ejector pin bottom plate is provided with ejector pins, the ejector pin face plate, the rear mold plate and the rear mold core are provided with ejector pin passing holes, and a nozzle separating insert is arranged in the rear mold core and provided with a sprue making the main runner and the cavity communicated. According to the automatic nozzle cutting device, in the injection molding process, plastic melt enters the cavity to be formed from the sprue; in the injection product pushing-out process, an injection product is pushed out by the ejector pins below the joint of the injection product and the sprue, the injection product is separated from a sprue nozzle and smoothly pushed out, a main runner nozzle and the separated sprue nozzle are also pushed out for discharging under the action of the ejector pins, and thus it is unnecessary to remove the nozzles manually after injection molding is completed; in this way, the process is simplified, labor is saved, product quality is guaranteed, production efficiency is improved, automatic production is achieved, and enterprise competitiveness is improved.
Description
Technical field
The invention belongs to injection mold technical field, specifically refer to a kind of automatic water gate cutting device.
Background technology
At present, in plastic cement products injection moulding production process, in order to produce with easy to process, what usually adopt style big water gap enters glue mode, but after production injection moulding, needs manually to go processing to cut away the mouth of a river in a large number, time-consumingly takes a lot of work, and production efficiency is very low; The artificial excision mouth of a river depends on the skills involved in the labour of workman to a great extent, otherwise is easy to damage product, reduces product quality, causes seed output and quality can not meet the demand of client, reduce the market competitiveness of enterprise.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of automatic water gate cutting device, under the prerequisite ensureing injecting products quality, realizes the object of saving operation and enhancing productivity.
For solving the problems of the technologies described above, the present invention realizes by the following technical solutions:
A kind of automatic water gate cutting device, the rear cavity comprise the thimble panel be located on Ejector Retainer Plate, being positioned at the rear pattern plate above thimble panel and being located on rear pattern plate, rear cavity is provided with sprue and die cavity, Ejector Retainer Plate is provided with thimble, thimble panel, rear pattern plate and rear cavity are respectively arranged with thimble via hole, be provided with a mouthful mold insert of cutting off the water supply in described rear cavity, cut off the water supply mouthful mold insert is provided be communicated with sprue and die cavity enter running channel.
Preferably, above-mentioned enter running channel be taper, tapering is 35-45 degree.
Preferably, above-mentioned thimble is positioned at the below of injecting products, the sprue mouth of a river and injecting products and gum intaking passage mouth of a river intersection.
Preferably, being positioned at thimble below injecting products and gum intaking passage mouth of a river intersection is flat thimble.
The present invention has following remarkable result compared to existing technology:
Automatic water gate cutting device reasonable in design of the present invention, by arranging a mouthful mold insert of cutting off the water supply in rear cavity, and cut off the water supply mouthful mold insert arranges be communicated with sprue and die cavity enter running channel, thus during injection moulding, plastic cement melt passes through to flow into mold cavity forming into running channel from sprue, after injecting products is shaping, when releasing injecting products, injecting products released by thimble below injecting products and gum intaking passage mouth of a river intersection, injecting products and the gum intaking passage mouth of a river depart to be released smoothly, and the sprue mouth of a river and the gum intaking passage mouth of a river after departing from also are pushed out blanking under the effect of thimble, artificial removal's regrinding-material is used again after completing without the need to injection moulding, save operation and labour, ensure that the quality of product, improve production efficiency, realize automated production, improve enterprise competitiveness.

Detailed description of the invention
For the ease of the understanding of those skilled in the art, below in conjunction with specific embodiment and accompanying drawing, structural principle of the present invention is further described in detail:
As shown in accompanying drawing 1-7, a kind of automatic water gate cutting device, be applied in injection mold, comprise thimble panel 2, Ejector Retainer Plate 1, rear pattern plate 3 and rear cavity 4, Ejector Retainer Plate 1 is located at by thimble panel 2, rear pattern plate 3 is located at above thimble panel 2, rear cavity 4 is located at rear pattern plate 3, rear cavity 4 is provided with sprue and die cavity, Ejector Retainer Plate 1 is provided with thimble 5, thimble 5 is positioned at injecting products 10, the sprue mouth of a river 20 and injecting products 10 and the below of the gum intaking passage mouth of a river 30 intersection, and thimble panel 2, rear pattern plate 3 and rear cavity 4 are respectively arranged with thimble via hole.
In the present embodiment, in rear cavity 4, be provided with mouthful mold insert 6 of cutting off the water supply, cut off the water supply mouthful mold insert 6 is provided be communicated with sprue and die cavity enter running channel 61, enter running channel 61 in taper, tapering is 35-45 degree, is convenient to the gum intaking passage mouth of a river 30 and releases.During injection moulding, plastic cement melt flows to cut off the water supply from sprue and mouthful mold insert 6 enters running channel 61, and plastic cement melt passes through to flow into mold cavity forming into running channel 61 again; After injecting products 10 is shaping, when releasing injecting products 10, thimble 5 is released with the gum intaking passage mouth of a river 30 intersection at injecting products 10, the sprue mouth of a river 20 and injecting products 10 simultaneously, when thimble 5 releases injecting products 10 at injecting products 10 with the gum intaking passage mouth of a river 30 intersection, injecting products 10 and the gum intaking passage mouth of a river 30 are departed from released smoothly, and the sprue mouth of a river 20 and the gum intaking passage mouth of a river 30 after departing from also are pushed out blanking under the effect of thimble 5.
