Abstract
The utility model provides a be used for injection mold to reduce decentered mechanism of long and thin core, include: a die, the up end of die forms a runner, a die core, die core slidable set up in in the die, a long and thin core and a long and thin mold core fixing plate, long and thin core is fixed set up in long and thin mold core fixing plate's lower terminal surface, set up a long and thin core storage tank in the die, setting that long and thin core can make a round trip in the middle part of long and thin core storage tank, the die core corresponds long and thin core setting, and be in the lower part of die, the up end of die core is replaced the lower terminal surface of long and thin core. Have and effectively to prevent long and thin core bending deformation, prevent that product inhomogeneity of wall thickness is even, can effectively improve injection mold work efficiency and reduce the advantage of aspects such as mould loss.
Description
Technical field
The utility model relates to injection mold technical field, particularly relates to a kind of mechanism reducing elongated core bias for injection mold.
Background technology
A kind of processing method used when injection mo(u)lding is some complex-shaped parts of batch production.The material melted that is heated is injected die cavity by high pressure by concrete finger, after cooling curing, obtains formed products.
Injection mold is a kind of instrument producing plasthetics; Also be the instrument giving plasthetics complete structure and accurate dimension.
Injection mold is made up of dynamic model and cover half two parts, and dynamic model is arranged on the moving die plate of injection (mo(u)lding) machine, and cover half is arranged on the fixed form of injection (mo(u)lding) machine.When injection moulding, dynamic model and cover half close and form running gate system and die cavity, and during die sinking, dynamic model is separated to take out plastic products with cover half.
In prior art in injection mold, have a class application very widely tubular plastic goods (as plastic tube) have very dark hole, on the mould making these goods, have elongated core, core forms the part of cavity when making plastic part shaping.When the plastics of melting inject die cavity along cast gate, elongated core is subject to the extruding of the plastics of uneven melting, can produce bending, forms the uneven of product wall thickness.
Summary of the invention
In view of the elongated core of injection mold in prior art easily can produce bending in the extruding of the plastics being subject to uneven melting, the deficiency of the uneven aspect of the product wall thickness formed.The purpose of this utility model is that providing one to have can effectively prevent slender type chip bending to be out of shape, prevent product wall unevenness even, effectively can improve the mechanism reducing elongated core bias for injection mold of the aspect advantages such as injection mold operating efficiency and the loss of reduction mould.
For realizing above-mentioned purpose of the present utility model, the utility model provides a kind of mechanism reducing elongated core bias for injection mold, the described mechanism reducing elongated core bias for injection mold comprises: a die, and the upper surface of described die forms a cast gate; One die core, described die core is slidably arranged in described die; One elongated core and an elongated core fixing plate, described elongated core is fixedly installed on the lower surface of described elongated core fixing plate; Arrange an elongated core storage tank in described die, described elongated core can be arranged at the middle part of described elongated core storage tank back and forth; The corresponding described elongated core of described die core is arranged, and is in the bottom of described die; The upper surface of described die core is supported in the lower surface of described elongated core.
According to above-mentioned design of the present utility model, the diameter of described die core is less than the diameter of described elongated core.
According to above-mentioned design of the present utility model, the lower surface of described elongated core forms an elongated core groove, and the upper surface of described die core is supported in described elongated core groove.
Advantage of the present utility model and beneficial effect are: have and can effectively prevent slender type chip bending to be out of shape, prevent product wall unevenness even, effectively can improve the advantage of the aspects such as injection mold operating efficiency and the loss of reduction mould.
Accompanying drawing explanation
Fig. 1 a kind of cross section structure schematic diagram reducing the mechanism of elongated core bias for injection mold of the present utility model.
Detailed description of the invention
In order to further illustrate principle of the present utility model and structure, now by reference to the accompanying drawings preferred embodiment of the present utility model is described in detail, but described embodiment is only the use providing and illustrate with explanation, can not be used for limiting scope of patent protection of the present utility model.
As shown in Figure 1 for a kind of mechanism reducing elongated core bias for injection mold of the present utility model, the described mechanism reducing elongated core bias for injection mold comprises: a die 1, and the upper surface of described die 1 forms a cast gate 11; One die core 2, described die core 2 is slidably arranged in described die 1; One elongated core 3 and an elongated core fixing plate 4, described elongated core 3 is fixedly installed on the lower surface of described elongated core fixing plate 4; Arrange an elongated core storage tank 12 in described die 1, described elongated core 3 can be arranged at the middle part of described elongated core storage tank 12 back and forth; The corresponding described elongated core of described die core 2 arranges 3, and is in the bottom of described die 1; The upper surface of described die core 2 is supported in the lower surface of described elongated core 3.
According to above-mentioned design of the present utility model, the diameter of described die core 2 is less than the diameter of described elongated core 3.
According to above-mentioned design of the present utility model, the lower surface of described elongated core 3 forms an elongated core groove 31, and the upper surface of described die core 2 is supported in described elongated core groove 31.
Of the present utility modelly a kind ofly reduce the mechanism of elongated core bias before injection moulding for injection mold, die core 2 in die 1 first withstands elongated core 3(outside and withstands elongated core 3 by the magnetic valve shake-up hydraulic mechanism die core 2 realized in die 1), increase the rigidity of elongated core 3.
In injection moulding process, when the plastics of melting are about to the die cavity being full of die 1, die core 2 in die 1 returns original position (the outside die core 2 realized in die 1 by magnetic valve shake-up hydraulic mechanism returns original position), the plastics be melted due to the major part of now elongated core 3 encase, and the plastics of melting continue the die cavity filling up die 1.In this process, the amount of bow of elongated core 3 reduces greatly.
Advantage of the present utility model and beneficial effect are: have and can effectively prevent slender type chip bending to be out of shape, prevent product wall unevenness even, effectively can improve the advantage of the aspects such as injection mold operating efficiency and the loss of reduction mould.
The variant that foregoing is only preferred embodiment of the present utility model and exemplifies; be not used for limiting the utility model; every within spirit of the present utility model and principle; done any need not the amendment of creative thinking and improvement, all should be included within protection domain of the present utility model.
