Abstract
The counterdie the utility model discloses a kind of fascia injection mold with buffering road, comprise patrix, matching with patrix, the pouring gate structure through upper die and lower die; Patrix is made up of punch and upper plate, and the bottom of punch is provided with locating dowel; Punch is provided with core, and core is provided with aperture, and aperture is communicated with pouring gate structure; Counterdie is made up of die and lower shoe, and the upper surface of die is provided with the locating hole matched with locating dowel; Position corresponding with core on die is provided with die cavity; Pouring gate structure comprises sprue and runner, is provided with buffering road between sprue and runner.The utility model is matched by locating dowel and locating hole, effectively can improve the accuracy that upper die and lower die coordinate; By increasing buffering road between sprue and runner, after fluid enters buffering road, flow velocity and the pressure of fluid can well be reduced, reducing the probability that transparent injection-molded parts develops and prints vestige appearance, simple and practical, improve production efficiency.
Description
Technical field
The utility model relates to injection molding apparatus field, particularly a kind of fascia injection mold with buffering road.
Background technology
Mould is modern industry, particularly the industrial requisite technological equipment such as automobile, radio, aviation, electrical equipment and electrical, instrument, instrument, commodity.The flow passage system of injection mold refers to the flow channel of melt from the nozzle of injector to die cavity.In injection moulding process, plastic melt enters mold cavity through flow passage system and nozzle, runner and cast gate, and the quality of flow passage system design, has very important impact to the quality of moulding and productivity effect.Common flow passage system by sprue, runner, cast gate, cold slug well and die cavity five part form.
The pouring gate structure of existing injection mold is in injection moulding process, and plastic melt is through runner time, and plastic melt is all generally directly by directly carrying out injection moulding after sprue and runner.When injection molding, there is the technological deficiency that cannot calibrate in traditional injection mold.
Realizing in process of the present utility model, inventor finds that prior art at least exists following problem:
The flow velocity of fluid is very large on the one hand, and the pressure of fluid also can be larger, finally may leave the vestige developed and printed on product, particularly when some transparent injected-moulded workpiece of production, these are developed and printed will be more obvious, not only affect quality and the outward appearance of product, also can bring the worry of quality and leakage aspect to consumer.Patrix, when falling, accurately cannot aim at counterdie.
Summary of the invention
In order to solve the problem of prior art, the utility model embodiment provides a kind of fascia injection mold with buffering road.Described technical scheme is as follows:
The utility model embodiment provides a kind of fascia injection mold with buffering road, described in there is buffering road fascia injection mold comprise patrix, the counterdie that matches with described patrix, pouring gate structure through described patrix and described counterdie;
Described patrix is made up of punch and upper plate, and the bottom of described punch is provided with locating dowel; Described punch is provided with core, and described core is provided with aperture, and described aperture is communicated with pouring gate structure;
Described counterdie is made up of die and lower shoe, and the upper surface of described die is provided with the locating hole matched with described locating dowel; Position corresponding with described core on described die is provided with die cavity;
Described pouring gate structure comprises sprue and runner, is provided with buffering road between described sprue and described runner.
Described buffering road is circular arc buffering road.
Described buffering road is " L " shape buffering road.
Described locating dowel is two and two or more.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:
Matched by locating dowel and locating hole, effectively can improve the accuracy that upper die and lower die coordinate; By increasing buffering road between sprue and runner, after fluid enters buffering road, flow velocity and the pressure of fluid can well be reduced, reducing the probability that transparent injection-molded parts develops and prints vestige appearance, simple and practical, improve production efficiency.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the patrix that the utility model embodiment provides;
Fig. 2 is the structural representation of the counterdie that the utility model embodiment provides;
Fig. 3 is the structural representation of the pouring gate structure that the utility model embodiment provides.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
The utility model embodiment provides a kind of fascia injection mold with buffering road, see Fig. 1, described in there is buffering road fascia injection mold comprise patrix 1, the counterdie 2 that matches with patrix 1, pouring gate structure 3 through patrix 1 and counterdie 2.
Particularly, patrix 1 is made up of punch 11 and upper plate 12, and the top of upper plate 12 is provided with pouring gate structure 3, and the bottom of punch 11 is provided with multiple locating dowel 110, and punch 11 is provided with core 111, and core 111 is provided with aperture, and aperture is communicated with pouring gate structure 3.
Particularly, see Fig. 2, counterdie 2 is made up of die 21 and lower shoe 22, and the upper surface of die 21 is provided with the locating hole 210 matched with locating dowel 110, and position corresponding with core 111 on die 21 is provided with die cavity 211.
Particularly, see Fig. 3, pouring gate structure 3 comprises sprue 31 and runner 32, is provided with buffering road 33 between sprue 31 and runner 32; Buffering road 33 is circular arc or L shape.
When fluid enters runner by cast gate time, first runner have passed through sprue, then after entering into runner by buffering road, finally enter into die cavity, flow velocity and the pressure of fluid can well be reduced like this in centre, reduce the probability that transparent injection-molded parts develops and prints vestige appearance, simple and practical, improve production efficiency.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:
Matched by locating dowel and locating hole, effectively can improve the accuracy that upper die and lower die coordinate; By increasing buffering road between sprue and runner, after fluid enters buffering road, flow velocity and the pressure of fluid can well be reduced, reducing the probability that transparent injection-molded parts develops and prints vestige appearance, simple and practical, improve production efficiency.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
