Abstract

The utility model discloses a sprue bush without plastic residue, comprising a sprue bush body, wherein the sprue bush body is internally provided with a runner; the top end of the runner is provided with a small-diameter sprue; a downward splitter is arranged at the sprue in the runner and vertically arranged along the axis of the runner; and two side edges of the splitter are completely embedded into the inner walls of the runner. The sprue bush without plastic residue has simple structure and strong practicability; and the splitter can completely eliminate the generation of the plastic residue and effectively shorten the cooling time, thus shortening the production period so as to improve the production efficiency and the qualification rate of the product.

Description

No collodion silk formula sprue bush
[technical field]
The utility model relates to a kind of sprue bush of injection mold, particularly a kind of no collodion silk formula sprue bush.
[background technology]
Sprue bush is a kind of lining that is used to connect injection machine and injection mold, and it is sprue bushing again, is to allow the hot gluse size of fusion drain into the runner part of mold cavity inside from the nozzle of injection machine.In injection mold, owing to sprue will contact with high temperature sizing material and injection machine nozzle, so the sprue of mould partly is usually designed to the sprue bush of detachable replacing.Because of the temperature at nozzle place higher, all there is near the slower problem of melt cooling the cast gate in existing sprue bush, if cool time is insufficient, have silk thread shape sizing material during die sinking and pull out, on the runner of injection machine nozzle and sprue bush cast gate contact position, form collodion silk, especially during the product of materials such as injection moulding PP, PET, be easier on runner, produce elongated collodion silk, and this collodion silk can adhere to product surface in product taking-up process, has a strong impact on product appearance, causes product rejection.The present normal generation of adopting the way that prolongs cool time to eliminate collodion silk, injection cycle has just extended greatly like this, causes the low and injection moulding cost raising of production efficiency.
[utility model content]
The purpose of this utility model is: improve above-mentioned deficiency of the prior art, a kind of no collodion silk formula sprue bush is provided, this kind sprue bush can well be eliminated the generation of collodion silk, and need not to spend too high cost and do extra work.
The technical solution of the utility model is achieved in that it comprises the sprue bush body, be provided with gate in the sprue bush body, the top of gate is the path inlet, its improvements are: be provided with downward splitter in the inlet place in gate, splitter vertically is located on the axis direction of gate, and the dual-side of splitter embeds the inwall of gate fully;
In the above-mentioned no collodion silk formula sprue bush, described splitter is a sheet metal;
In the above-mentioned no collodion silk formula sprue bush, described sheet metal is made by heat resisting steel;
In the above-mentioned no collodion silk formula sprue bush, the thickness of described splitter is 0.3~0.6mm;
In the above-mentioned no collodion silk formula sprue bush, the height of described splitter is 3~4mm.
The beneficial effects of the utility model are: simple in structure, practical, the cooling velocity that the fusion sizing material of having accelerated the sprue bush oral area is set of splitter, can well eliminate the generation of collodion silk, and can effectively reduce cool time, shorten the production cycle, improved the qualification rate of production efficiency and product, reduced the injection moulding cost.
[description of drawings]
Below in conjunction with accompanying drawing in detail concrete structure of the present utility model is described in detail
Fig. 1 is the structural representation of no collodion silk formula sprue bush
Fig. 2 is the vertical view of no collodion silk formula sprue bush
The flow passage structure schematic diagram that Fig. 3 is to use the injection moulding of no collodion silk formula sprue bush to come out
Among the figure: 1, sprue bush body; 11, gate; 12, inlet; 13, nozzle locating slot; 2, splitter; 3, runner.
[specific embodiment]
As depicted in figs. 1 and 2, no collodion silk formula sprue bush of the present utility model comprises sprue bush body 1 and splitter 2, be provided with the gate 11 that vertically runs through sprue bush body 1 in the sprue bush body 1, gate 11 is the sprue part of injection mold, it is a bellmouth, and the top of gate 11 is the inlet 12 of path.In order to prevent that the fusion sizing material from revealing from inlet 12, offer the nozzle locating slot 13 of arc at the top of sprue bush body 1 end face, nozzle locating slot 13 is coaxial with gate 11, and nozzle locating slot 13 is connected mutually with inlet 12.Should guarantee during manufacturing that this bellmouth is coaxial with the cylindrical of sprue bush body 1, so that when mould is installed, nozzle locating slot 13 and inlet 12 on the sprue bush body 1 are aimed at the nozzle of injector by locating ring.In gate 11, be provided with downward splitter 2 in inlet 12 places, splitter 2 is a sheet metal, preferably, sheet metal is made by heat resisting steel, splitter 2 vertically is located on the axis direction of gate 11 by the mode that the top from sprue bush body 1 presses downward to, make the dual-side of splitter 2 embed the inwall of gate 11 fully, with fixedly connected splitter 2 and sprue bush body 1.For ensureing that splitter 2 does not hinder into glue when the injecting glue, and it is smooth to make this locate away solation, and the THICKNESS CONTROL that should make splitter 2 is between 0.3~0.6mm, and the height of splitter 2 is between 3~4mm.
When using this novel no collodion silk formula sprue bush injecting glue, the nozzle of injector is connected to nozzle locating slot 13 on the sprue bush body 1, nozzle is spurted into gate 11 to the fusion sizing material from inlet 12, the fusion sizing material is divided into two strands of melten gels at inlet 12 places by splitter 2 and enters gate 11, and inject the die cavity of moulds via gate 11, obtain finished product after the moulding to be cooled.As shown in Figure 3, in cooling procedure, splitter 2 is divided into two parts with the sizing material at close-range shot mouth place in the gate 11, quickened the quick cooling of this position sizing material, the runner 3 that injection moulding is come out does not produce collodion silk, has improved the qualification rate of product, has effectively improved production efficiency simultaneously.
Described above only is preferred embodiment of the present utility model, and above-mentioned specific embodiment is not to restriction of the present utility model.In technological thought category of the present utility model, various distortion and modification can appear, and the retouching that all those of ordinary skill in the art make according to above description, revise or be equal to replacement, all belong to the scope that the utility model is protected.
