Abstract
The invention discloses a mould with an anti-wire-drawing sheet. The mould with the anti-wire-drawing sheet comprises a female template and a sprue vertically fixed in the female template, wherein an inlet sprue is formed in the arc top face of the head of the sprue; the anti-wire-drawing sheet for preventing wire-drawing when a stub bar is drawn out is fixed on the head of the sprue; and the anti-wire-drawing sheet is located on the sprue and is vertically arranged. The mould with the anti-wire-drawing sheet provided by the invention fixes the vertical anti-wire-drawing sheet at the head of the sprue; and the anti-wire-drawing sheet is simple to machine and is convenient to mount and dismount, and can be effectively prevented from the wire-drawing of the stub bar, so that the glue wires are prevented from entering the inside of a mould core, and the quality and the appearance of the product can be improved.
Description
Technical field
The present invention relates to mould, be specifically related to a kind of mould with anti-wire drawing sheet.
Background technology
The sprue bushing of mould also makes sprue bush, Guan Zui, cast gate fill with, and is be used to the metal fittings that connect into mould and injection machine, can allow the plastic material of melting be injected into mould inside from the nozzle of injection machine.
When producing injecting products, the mould temperature of mould needs very high sometimes, and the stub bar of plastic cement often can be stained with collodion silk; when stub bar is extracted sprue bushing out, the collodion silk progressive die benevolence that may drop, like this; time next injection moulding, collodion silk will be stayed in product, and product appearance and quality are impacted.
Summary of the invention
Technical problem to be solved by this invention is the stub bar easy wire drawing when extracting out in sprue bushing, affects the problem of product appearance and quality.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is to provide a kind of mould with anti-wire drawing sheet, comprise caster and vertically be fixed on sprue bushing on described caster, have into cast gate on the arc top surface of described sprue bushing head, be fixed with on described sprue bushing head and prevent from producing when stub bar from extracting out the anti-wire drawing sheet of wire drawing, described anti-wire drawing sheet is positioned at and describedly advances on cast gate and vertically arrange.
In the mould of the anti-wire drawing sheet of above-mentioned band, have rectangular recess on the arc top surface of described sprue bushing head, described anti-wire drawing sheet is rectangle, be inlaid in described rectangular recess, and the end face of described anti-wire drawing sheet is concordant with the horizontal top surface of described sprue bushing head.
The mould of the anti-wire drawing sheet of band provided by the invention is fixed with vertical anti-wire drawing sheet on the sprue bushing head, anti-wire drawing sheet processing is simple, and installation and removal are convenient, can effectively prevent the stub bar wire drawing, thereby avoided collodion silk to enter die inside, improved quality and the outward appearance of product.
Description of drawings
Fig. 1 is the structural representation of sprue bushing provided by the invention and anti-wire drawing sheet.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is made detailed explanation.
As shown in Figure 1, the mould of the anti-wire drawing sheet of band provided by the invention comprises caster 1 and vertically is fixed on sprue bushing 2 on caster 1, have into cast gate 22 on the arc top surface 21 of sprue bushing head, also be fixed with on the sprue bushing head and prevent from producing when stub bar from extracting out the anti-wire drawing sheet 3 of wire drawing, anti-wire drawing sheet 3 is positioned on cast gate 22 and vertically and arranges.
Have rectangular recess on the arc top surface 21 of sprue bushing head, anti-wire drawing sheet 3 is rectangle, be inlaid in rectangular recess, and the end face of anti-wire drawing sheet 3 is concordant with the horizontal top surface 23 of sprue bushing head.
Anti-wire drawing sheet 3 can effectively prevent the stub bar wire drawing, avoids drawing head to enter die inside, improves quality and the outward appearance of product.Anti-wire drawing sheet 3 processing are simple, and installation and removal are convenient, but often are injection molding the machine punching press, understand for a long time attenuation, therefore need often to change.
Sealing device for valve provided by the invention has been realized the sealing of valve by the dentiform gasket 3 between valve gap 1 and valve body 2 and annular boss 23, simple in structure, does not need higher machining accuracy, good sealing effect.
The present invention is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present invention, and every have identical or close technical scheme with the present invention, within all falling into protection scope of the present invention.
