Abstract

The utility model relates to a runner structure of a plastic die. The runner structure comprises a fixed die seat plate, a poker fixing plate, a fixed die plate, a fixing plate, a movable die plate and a nozzle, wherein the nozzle is arranged on the fixed die seat plate; the lower end of the nozzle penetrates through the poker fixing plate and the fixed die plate; an H-shaped main runner and an H-shaped sub-runner are arranged between the fixed die plate and the fixing plate; the lower end part of the nozzle is communicated with a central main runner of the H-shaped main runner; two end parts of side main runners at two sides of the H-shaped main runner are respectively connected with a sub-runner of the H-shaped sub-runner; a plurality of penetrating pouring gates are respectively arranged at two sides of the lateral runners at two sides of the H-shaped sub-runner on the fixing plate; a plurality of cavities communicated with the pouring gates are arranged on the movable die plate. The runner structure has the advantages that the filling from the top of each cavity is adopted; the filling from the side of a product in the past is changed into the filling from the top of the product, so that a long and thin-wall product is even in wall thickness and good in straightness.

Description

A kind of flow passage structure of mould of plastics
Technical field
The utility model relates to the flow passage structure of a kind of injection mold, particularly a kind of mould of plastics.
Background technology
Adopt injection mold to produce plastic product, particularly during the product of some elongated and thin-walleds, but prior art adopts traditional approach production, namely comprise a secondary mould, glue is advanced in the side that the charging runner of mould and cast gate are positioned at product, as shown in Figure 1, annotate mouth 1 and connect by runner and cast gate 3, cast gate 3 is positioned at the side of product 2 and advances glue.
Make easily the wall unevenness of product even for elongated and thin-wall product after the mechanical feature injection moulding of above-mentioned mould, flexural deformation is serious, and defect rate is high.
Summary of the invention
The purpose of this utility model is exactly the deficiency in the background technology, and a kind of flow passage structure of mould of plastics is provided.
For achieving the above object, the utility model adopts following technical scheme: a kind of flow passage structure of mould of plastics, comprise top clamping plate, material bar fixed head, solid plate, fixed head, moving platen and be arranged at notes mouth on the top clamping plate, annotate the mouth lower end and run through material bar fixed head and solid plate, be provided with H shape sprue between solid plate and the fixed head, H shape runner, annotating end, mouth lower end is communicated with the center main runner of H shape sprue, the both ends of the side sprue of H shape sprue both sides are connected with road in the shunting of H shape runner respectively, the side runner both sides of H shape runner both sides are respectively equipped with the cast gate of some perforations on the fixed head, and moving platen is provided with some die cavities that are communicated with each cast gate.
The utility model is compared with background technology, has the top of having adopted from product and advances glue, advances glue from the product side and changes into from the product top and advance glue original, makes the product wall thickness of elongated and thin-walled even, and linearity is good.
Description of drawings
Fig. 1 is the structural representation that glue is advanced in the side of a kind of mould of plastics described in the prior art.
Fig. 2 is the flow passage structure schematic diagram of mould of plastics described in the utility model.
Fig. 3 is that its runner of flow passage structure of mould of plastics described in the utility model is communicated with schematic diagram.
Fig. 4 is H shape runner and the schematic diagram that is communicated with of each cast gate.
The specific embodiment
Embodiment 1: such as Fig. 2-4.A kind of flow passage structure of mould of plastics, comprise top clamping plate 6, material bar fixed head 2, solid plate 1, fixed head 3, moving platen 10 and be arranged at notes mouth 4 on the top clamping plate 6, annotate mouth 4 lower ends and run through material bar fixed head 2 and solid plate 1, be provided with H shape sprue 5 between solid plate 1 and the fixed head 3, H shape runner 7, annotating end, mouth 4 lower end is communicated with the center main runner 51 of H shape sprue 5, the both ends of the side sprue 52 of H shape sprue 5 both sides are connected with road 71 in the shunting of H shape runner 7 respectively, side runner 72 both sides of H shape runner 7 both sides are respectively equipped with the cast gate 8 of some perforations on the fixed head 3, and moving platen 10 is provided with some die cavities 9 that are communicated with each cast gate 8.
During work, plastic solution enters in each cast gate 8 by annotating mouth 4, H shape sprue 5, H shape runner 7, and plastic solution enters the moulding that die cavity 9 is finished plastic product by cast gate 8 from the top of the die cavity 9 of making product.
Above-described only is preferred embodiment of the present utility model; should be understood that; for those of ordinary skill in the art; under the prerequisite that does not break away from core technology feature of the present invention; can also make some improvement and distortion, these improvement and distortion also should be considered as protection scope of the present invention.
