Abstract
The utility model discloses a main runner bushing mechanism of an injection mould. The main runner bushing mechanism comprises a bushing body (1), wherein the bushing body (1) is internally provided with a main runner penetrating through the bushing body; a feeding end (4) of the main runner (2) is communicated with a semi-circular groove (3) formed in the upper surface of the bushing body (1) and gradually increases in diameter towards a mould core direction; and the diameter of the feeding end (4) is 0.5-1mm more than that of an injector nozzle (5), and the radius of the semi-circular groove (3) is 1-2mm more than that of a spherical surface (6) of the injector nozzle. According to the main runner bushing mechanism, the diameter of the main runner gradually increases from the feeding end to the mould core direction, the feeding end is more than the injector nozzle in diameter and is provided with the semi-circular groove, so that a role of buffering plastic fluid is played, the injection molding quality is improved, no aggregated plastic is accumulated in the injection molding process, product demolding is facilitated, and the main runner bushing mechanism is simple in design and attractive in modeling and has a good application prospect.
Description
Technical field
The utility model relates to notebook component technology field, is specifically related to a kind of injection mold sprue bush mechanism.
Background technology
Existing injection mold sprue bush mechanism, sprue adopts cylinder design, and the diameter of feed end and runner is consistent, and in injection moulding process, accumulates easily and solidifyingly expects, thereby affect the demoulding of product.
The utility model content
The purpose of this utility model is to overcome deficiency of the prior art, a kind of injection mold sprue bush mechanism is provided, and the diameter of sprue from feed end to the die direction increases gradually, and the diameter of feed end is larger than the diameter of nozzle of injector, and be provided with semi-circular recesses, play the effect of buffering plastic liquid, improve the injection moulding quality, and can not produce and accumulate solidifying material, make things convenient for product stripping, simplicity of design causes attractive in appearancely, has a good application prospect.
In order to achieve the above object, the technical scheme that adopts of the utility model is:
A kind of injection mold sprue bush mechanism, comprise the lining body, be provided with the sprue of penetration liner body in the described lining body, it is characterized in that: the feed end of described sprue is connected with the semi-circular recesses of lining body upper surface setting, the feed end of described sprue increases gradually to the diameter of die direction, the diameter of described feed end is than the large 0.5-1mm of diameter of nozzle of injector, the large 1-2 mm of radius of the radius ratio nozzle of injector sphere of described semi-circular recesses.
Aforesaid a kind of injection mold sprue bush mechanism is characterized in that: the diameter of described feed end is than the large 0.7mm of diameter of nozzle of injector, the large 1.5mm of radius of the radius ratio nozzle of injector sphere of described semi-circular recesses.
The beneficial effects of the utility model are: injection mold sprue bush of the present utility model mechanism, the diameter of sprue from feed end to the die direction increases gradually, the diameter of feed end is larger than the diameter of nozzle of injector, can guarantee in injection moulding process, sprue can not produce and accumulate solidifying material, make things convenient for product stripping, and the semi-circular recesses with sprue UNICOM is set above the lining body, play the effect of buffering plastic liquid, can improve the injection moulding quality, simplicity of design causes attractive in appearancely, has a good application prospect.
Description of drawings
Fig. 1 is the structural representation of injection mold sprue bush of the present utility model mechanism.
The implication of mark is as follows in the accompanying drawing:
1: the lining body; 2: sprue; 3: semi-circular recesses; 4: feed end; 5: nozzle of injector; 6: the nozzle sphere.
The specific embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1, a kind of injection mold sprue bush mechanism, comprise lining body 1, be provided with the sprue 2 of penetration liner body in the described lining body 1, the feed end 4 of sprue 2 is connected with the semi-circular recesses 3 of lining body 1 upper surface setting, and semi-circular recesses 3 is than the large 1-2 mm of radius of nozzle of injector sphere 6, here preferred 1.5mm, semi-circular recesses 3 can cushion plastic liquid, improve the injection moulding quality, the feed end 4 of sprue 2 increases gradually to the diameter of die direction, and the diameter maximum is the twice of feed end 4 diameters, the die direction is illustrated A direction, the diameter of feed end 4 is than the large 0.5-1mm of diameter of nozzle of injector 5, and preferred 0.7mm guarantees in injection moulding process here, sprue can not produce and accumulate solidifying material, after injection moulding is finished, make things convenient for product stripping, simplicity of design, cause attractive in appearancely, have a good application prospect.
More than show and described basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is by appending claims and equivalent circle thereof.
