Abstract
The utility model provides a simple secondary ejection mechanism of an injection mold, which comprises a movable mold core, an ejection needle, a movable mold embedding element and a spring, wherein the movable mold embedding element consists of an embedding needle and a stop block arranged at the lower part of the embedding needle, the movable mold embedding element is arranged in a cavity of the movable mold core, the cavity consists of a first through hole and a second through hole, and forms a step between the first through hole and the second through hole, and the spring is sheathed and arranged on the embedding needle and is positioned in the second through hole. Compared with the prior art, the utility model adopts the simple secondary ejection mechanism, can smoothly disengage product clamping buckles with small stroke from the mold, and can realize the product ejection under the condition without influencing the product clamping buckle function and the appearance, so the intensity and the appearance of the clamping buckles of injection products can reach higher standards, secondly, because of the adoption of the ejection mechanism, the mold maintenance is convenient, in addition, the stability of the mechanism is high, and the embedding element can be conveniently replaced when the product shape is changed.
Description
Technical field
The utility model relates to a kind of injection molding ejecting mechanism, particularly, relates to a kind of simple and easy secondary ejecting mechanism that is used for injection mold.
Background technology
In the mold releasability process, comprise the product of buckle or similar structures as fruit product, generally adopt the taper pin pushing method or force pushing method.When adopting the taper pin pushing method, taper pin must be done very thin so, and such requirement of strength that often can not satisfy mould, when product ejects, cause taper pin to fracture easily, increase labour cost and Master Cost, for example Chinese patent application number has disclosed such structure for CN200620055838.1 " inclined pin structure of mould and mould thereof ".When taking to force pushing method, then easily the product buckle is drawn whitely, cause product rejection.
The utility model content
Problem to be solved in the utility model is: at the problem of above-mentioned existence provide a kind of simple in structure, cost is low and can guarantee the simple and easy secondary ejecting mechanism of injection mold of the smooth demoulding of product buckle.
The technical scheme that the utility model adopted is: provide a kind of injection mold simple and easy secondary ejecting mechanism, it comprises dynamic mould core and thimble, it is characterized in that: also comprise dynamic model mold insert and spring, described dynamic model mold insert is made of pin and the block that is arranged on described pin bottom, described dynamic model mold insert is arranged in the cavity of described dynamic mould core, and the die cavity that the buckle shape between the head of described pin and the dynamic mould core on formation and the product matches, the cavity of described dynamic mould core is then formed by first through hole that is complementary with described pin with second through hole that described block is complementary, and first, form a step between second through hole, described spring housing is located on the described pin and is arranged in second through hole, and this spring on, the lower end is against respectively on described step and the block.Further, the simple and easy secondary ejecting mechanism of described injection mold also comprises limited block, and described limited block is fixed on the described dynamic mould core and extends to the below of described block.
Compared with prior art, the utility model takes simple and easy secondary ejecting mechanism to break away from from mould by successfully that stroke is less product buckle, be implemented in and finish ejecting of product under the situation that does not influence product buckle function and outward appearance, make the intensity of buckle of injecting products and outward appearance arrive higher standard; Secondly, take this ejecting mechanism to make that mold repair is comparatively convenient and mechanism stability is better, when shape of product is changed, can change mold insert easily; In addition, the utility model prevents that by limited block is set the mold insert parts from coming off, and can play spacing effect again when mold insert resets from dynamic mould core.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing:
Embodiment: as shown in Figures 1 to 4, the simple and easy secondary ejecting mechanism of the injection mold in the present embodiment comprises dynamic mould core 4, thimble 7, dynamic model mold insert 2, limited block 6 and spring 3, and its matched moulds state as shown in Figure 1.
Described dynamic model mold insert 2 is made of pin 21 and the block 22 that is arranged on described pin 21 bottoms, specifically as shown in Figure 4.Described dynamic model mold insert 2 is arranged in the cavity of described dynamic mould core 4, the cavity of described dynamic mould core 4 is formed by first through hole that is complementary with described pin 21 and with second through hole that described block 22 is complementary, and between first through hole and second through hole formation one step 5.The die cavity that 1 buckle 8 shapes match on formation and the product between the head of described pin 21 and the dynamic mould core 4.In the present embodiment, described second through hole and described block 22 are cylindric.
Described spring 3 is set on the described pin 2 and is arranged in second through hole, and the upper and lower end of this spring is against respectively on described step 5 and the block 22.
Described limited block 6 is fixed on the described dynamic mould core 4 and extends to the below of described block 22, and in the present embodiment, described limited block 6 is fixed on the described dynamic mould core 4 by screw.Described limited block 6 makes described dynamic model mold insert 2 and spring 3 can not drop when splitting out in that die is single, thereby play the effect that prevents that described dynamic model mold insert 2 and spring 3 from dropping, and can when spring 3 resets described dynamic model mold insert 2, play spacing effect described dynamic model mold insert 2.
Described thimble 7 is assembled on the following ejector retainner plate of mould.
Product 1 (for example car light) buckle 8 behind has been shown among Fig. 5, and the stroke that the buckle 8 of product 1 ejects is very little.The process that the utility model ejects product 1 is as follows: at first, thimble 7 ejects product 1, product 1 drives described dynamic model mold insert 2 and spring 3 ejects together, when described dynamic model mold insert 2 is covered stroke S, because described spring 3 elastic force equal the pulling force of the buckle 8 of product 1, the just no longer motion of described dynamic model mold insert 2, this moment, product broke away from dynamic mould core 4 parts, thereby finished the work that ejects for the first time, specifically as shown in Figure 2; Then, described thimble 7 continues product 1 is ejected, thereby buckle Final 8 system is broken away from described dynamic model mold insert 2, this moment is because product 1 has broken away from described dynamic mould core 4, so when thimble 7 continues to eject, can easily buckle 8 and described dynamic model mold insert 2 be broken away from, finish ejecting work for the second time, specifically as shown in Figure 3.It will be appreciated by those skilled in the art that when buckle 8 when product 1 breaks away from described dynamic model mold insert 2 that be not subjected under the situation of other pulling force at described dynamic model mold insert 2, the spring 3 of compressive state is easy to by its elastic force described dynamic model mold insert 2 be resetted.
