Abstract
The utility model discloses a mold for manufacturing a pre-tightening chain, comprising an upper mold part, a lower mold part, a guide mechanism, a sprue and a slanted guide pillar. The upper mold part is provided with an upper mold kernel, the lower mold part is provided with a mold kernel, and slides are arranged between the upper mold part and the lower mold part; the upper mold kernel, the lower mold kernel and the slides at two sides jointly form two parting surfaces which are vertical to each other, and the two parting surfaces and the parting direction are in an angle of 30-60; and one side of the slanted guide pillar is provided with a hold-down strip; and one side of the pouring port is provided with a hook needle. According to the mold, the vertical and horizontal slides are turned into the slides at the 45-degree position, the product has no under-cut in the stripping direction and naturally strips off after the mold is parted, so that manually taking out the product is saved, and the cost is saved; and the problems of burrs of the product during stripping and spring failure are solved, and the productivity is improved.
Description
Technical field
The utility model relates to a kind of mould, is specifically related to a kind of mould for the manufacture of the pretension chain.
Background technology
The injection mold material that melts that refers to be heated is injected die cavity by high pressure, behind cooling curing, obtains the method for formed products.The method is applicable to the batch production of complex-shaped parts, is one of important processing method.Injection molding process is broadly divided into following 6 stages " matched moulds-injection-pressurize-cooling-die sinking-goods take out ", and above-mentioned technique is carried out repeatedly, just can continuously produce goods.
Existing mold easy stretcher strain when product stripping produces burr, and outward appearance appears to have defective, and spring easily lost efficacy in use, often need to go to safeguard, output is not high, waste of manpower.
The utility model content
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of mould for the manufacture of the pretension chain is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:
A kind of mould for the manufacture of the pretension chain, comprise part of the upper die, part of the lower die, guiding mechanism, sprue gate and Angle Pin, described part of the upper die is provided with upper cores, described part of the lower die is provided with lower die, be provided with slide block between described part of the upper die and the part of the lower die, the slide block of described upper cores, lower die and both sides is common to form two orthogonal die joints, and two described die joints and die sinking direction are 30-60 degree angle; Described Angle Pin one side is provided with press strip; Described sprue gate one side is provided with crochet hook.
Further, described die joint and die sinking direction are miter angle.
The beneficial effects of the utility model are:
Mould is transformed into the slide block of 45 degree positions by the slide block of vertical and horizontal direction, and there is not back-off in product at stripping direction, and product comes off after die sinking naturally, saves and manually gets product, saves cost.The burr that produce when solving product stripping, and the problem of spring failure improve production capacity.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, the general introduction of technical scheme, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and cooperate accompanying drawing to be described in detail as follows.The specific embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, consists of the application's a part, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 the utility model front view;
Fig. 2 the utility model top view.
Number in the figure explanation: 1, sprue gate, 2, guiding mechanism, 3, upper cores, 4, slide block, 5, lower die, 6, Angle Pin, 7, press strip, 8, crochet hook, 9, the part of the upper die, 10, the part of the lower die.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
With reference to Fig. 1, shown in Figure 2, a kind of mould for the manufacture of the pretension chain, comprise part of the upper die 9, part of the lower die 10, guiding mechanism 2, sprue gate 1 and Angle Pin 6, described part of the upper die 9 is provided with upper cores 3, described part of the lower die 10 is provided with lower die 5, be provided with slide block 4 between described part of the upper die 9 and the part of the lower die 10, the slide block of described upper cores 3, lower die 5 and both sides 4 is common to form two orthogonal die joints, and two described die joints and die sinking direction are 30-60 degree angle; Described Angle Pin 6 one sides are provided with press strip 7; Described sprue gate 1 one sides are provided with crochet hook 8.
Further, described die joint and die sinking direction are miter angle.
Mould is transformed into the slide block of 45 degree positions by the slide block of vertical and horizontal direction, and there is not back-off in product at stripping direction, and product comes off after die sinking naturally, saves and manually gets product, saves cost.
During the mould die sinking, under the effect of drag hook, break pin gate by crochet hook first, release running channel by stripper again.Slide block is opened under the guiding of Angle Pin again, and Realization of Product comes off naturally, need not to eject.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
