Abstract
The invention discloses an eccentricity preventing mechanism for a locating ring. The mechanism is applied to a mold and comprises a sprue bush and a locating ring, wherein the sprue bush is arranged above a mold runner and fixed in the mold, the locating ring is arranged above the sprue bush and fixed on an upper fixing plate of the mold, the locating ring comprises an extending part extending downwards from the bottom of the ring, the extending part is communicated with and concentric with the locating ring, and the extending part is sleeved on the upper end of the sprue bush. The eccentricity preventing mechanism for the locating ring is low in cost, simple in structure, convenient to process, suitable for all molds, and simultaneously capable of preventing the problems of wasting of mold testing time and severe machine pressure loss.
Description
[technical field]
The present invention relates to a kind of mould structure, be specifically related to a kind of locating ring and prevent eccentric stiffener.
[background technology]
On mould when injection machine, ensure that the sprue bush of mould is parallel with injection molding machine nozzle position and overlap completely, just need add a locating ring to positioning instant of mould.So-called locating ring, adds a concentric annulus in sprue bush outside exactly, and this annulus is identical with the size of the front mould plate hole of injection machine, by after this annulus fit on, just can ensure the sprue bush position of mould and injection molding machine nozzle position consistency.
As Fig. 1 illustrates, be locating ring of the prior art mechanism, locating ring 10 is parallel being pressed in above sprue bush 20, then utilizes screw 11 that this locating ring 10 is fixed on upper mounted plate 30, thereby ensures position and the injection molding machine nozzle position consistency of sprue bush 20.But; because screw 11 is empty avoiding in locating ring 10, in the time of fitter assembly, thereby can not ensure that locating ring 10 and sprue bush 20 are concentric; cause the nozzle of injection machine can not be completely and sprue bush 20 coincide, when result cannot complete die trial or die trial, the board pressure loss is serious.
In view of this, be in fact necessary to provide a kind of locating ring mechanism, above-mentionedly can not ensure the problem concentric with sprue bush when the assembling and positioning ring to solve, while avoiding completing die trial or die trial, the board pressure loss is serious.
[summary of the invention]
Therefore, the invention provides a kind of locating ring and prevent eccentric stiffener, this mechanism can solve and above-mentionedly in the time of assembling and positioning ring, can not ensure the problem concentric with sprue bush.
In order to arrive above-mentioned purpose, locating ring of the present invention prevents eccentric stiffener, and it is applied in mould, and this locating ring prevents that eccentric stiffener from comprising:
Sprue bush, it is located at the top of described mold runner and is fixed in described mould;
Locating ring, the upper mounted plate that it is located at the top of described sprue bush and is fixed on described mould, this locating ring has an extension downwards along its annulus bottom, and this extension is communicated with this locating ring and is concentric, and this extension is sheathed on the upper end of described sprue bush.
Preferably, described extension and described sprue bush close-fitting.
Preferably, described extension is hollow cylindrical.
Locating ring of the present invention prevents eccentric stiffener, thereby ensures concentricity by above-mentioned locating ring being enclosed within on described sprue bush, has avoided the empty avoiding of coping screw and locating ring and produces the decentraction problem of locating ring and sprue bush.
Compared to prior art, this locating ring prevents that the cost of eccentric stiffener is low, simple in structure and easy to process, is applicable to all moulds, and can avoid delaying the die trial time and cause the problem that the board pressure loss is serious.
[brief description of the drawings]
Fig. 1 illustrates as locating ring of the prior art mechanism.
Fig. 2 illustrates and prevents eccentric stiffener for locating ring of the present invention.
[detailed description of the invention]
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
Refer to Fig. 2 and illustrate, locating ring of the present invention prevents eccentric stiffener, and it is applied in mould, and this locating ring prevents that eccentric stiffener from comprising:
Sprue bush 200, it is located at the top of described mold runner and is fixed in described mould;
Locating ring 100, the upper mounted plate 300 that it is located at the top of described sprue bush 200 and is fixed on described mould by screw 111, this locating ring 100 has an extension 110 downwards along its annulus bottom, this extension 110 is communicated with this locating ring 100 and is concentric, and this extension 110 is sheathed on the upper end of described sprue bush 200.
Wherein, described extension 110 and described sprue bush 200 close-fittings.
Wherein, described extension 110 is hollow cylindrical.
In the present embodiment, locating ring of the present invention prevents eccentric stiffener, in the time of fitter assembly, by the upper end that is enclosed within sprue bush 200 of the extension of locating ring 100 110 close-fittings, thereby ensure the concentricity of locating ring 100 with sprue bush 200, then the upper mounted plate 300 that with screw 111, this locating ring 100 is fixed on to described mould, completes the assembling of locating ring 100.Because locating ring 100 is identical with the size in front moulding board of injection machine hole, ensure the concentric of sprue bush 200 and injection molding machine nozzle, thereby in the time of die trial, completed smoothly injection moulding, avoid the loss of board pressure.
Locating ring of the present invention prevents eccentric stiffener, thereby ensures concentricity by above-mentioned locating ring being enclosed within on described sprue bush, has avoided the empty avoiding of coping screw and locating ring and produces the decentraction problem of locating ring and sprue bush.
This locating ring prevents that the cost of eccentric stiffener is low, simple in structure and easy to process, is applicable to all moulds, and can avoid delaying the die trial time and cause the problem that the board pressure loss is serious.
Be pointed out that, the invention is not restricted to above-mentioned embodiment, any simple modification, equivalent variations and modification that any those skilled in the art do above-described embodiment based on technical solution of the present invention, all fall within the scope of protection of the present invention.
