Abstract
The utility model provides an injection molding mold gate structure, by the nozzle enter to water runner (1), mould sprue (2), runner (3), product edge structure (4), product runner defect regional (5), transparent product (6) are formed, mould sprue (2) go up to open and to have the nozzle to enter to water runner (1) and runner (3), runner (3) are divided the two -way symmetry to get into product marginal structure (4) to pour into a mould into transparent product (6), its characterized in that: runner runner (3) and product edge structure (4) between be equipped with the product and extend regional (7), make the melting plastics get into runner runners (3) back and mould plastics to the product through mould sprue (2) and extend region (7). The utility model discloses, simple structure, convenient operation, solution product runner department that can be fine bring turns white, send out the fog, stay appearance imperfections such as trace, has improved the qualification rate of product greatly.
Description
Technical field
The utility model relates to a kind of mould gate place of automotive-type injection-moulded plastic part Design of Dies structure, relates to the quality improving injection molding part cast gate place.
Background technology
Client is to the appearance requirement of injection mold part in continuous raising, and the cost that client drops into constantly reduces every year, and traditional handicraft is difficult to the requirement meeting client; Adding the precision of board, the debug difficulties of parameter, the defect solving Transparent Parts and appearance member is difficult in whole production process, cause the qualification rate of product low, last remaining product profit is difficult to the supply and demand maintaining links, and the competitiveness of company can decline; Although traditional mould enters gate location also devise cold slug well (being arranged on runner two), when plastics flow into cast gate, because the injection-moulding position of injection moulding speed, pressure, cast gate section confirms, the cold burden of leading portion can after random inflow runner, flowing into cast gate by the branch of runner is injected in die cavity, can be there is the trace that shoots material in product cast gate place product surface, a mist turns white, ripple glaze, can not meet market demands, cause and produce waste.
Summary of the invention
In order to overcome the above problems, the purpose of this utility model is to provide a kind of moulding mould gate structure, and be increases to have product extended structure between sprue channel and product edge structure, makes mould sprue and the optimization of sprue channel relative position.
The technical solution of the utility model is achieved in the following ways: a kind of moulding mould gate structure, entered to water runner by nozzle, mould sprue, sprue channel, product edge structure, product gate defect region, opaque products forms, described mould sprue has nozzle and enters to water runner and sprue channel, sprue channel symmetry point two tunnels enter product edge structure and pour into opaque products, it is characterized in that: between described sprue channel and product edge structure, be provided with product elongated area, molten plastic to be entered after sprue channel by the injection moulding of mould sprue to product elongated area.
Product gate defect region is provided with between described opaque products and product edge structure.
The utility model, structure is simple, easy to operate, and what can well solve that product cast gate place brings turns white, sends out the open defect such as mist, trace, substantially increases the qualification rate of product.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present utility model.
In figure: 1 nozzle enters to water runner, 2 mould sprues, 3 sprue channels, 4 product edge structures, 5 are product gate defect region, 6 be opaque products, 7 for product elongated area.
Detailed description of the invention
As shown in Figure 1, be the structural representation of prior art.The mould structure of cast gate place traditional design, be commonly referred to as " U " runner, molten plastic enters sprue channel 3 and directly enters to water, the cold burden that nozzle enters to water runner 1 leading portion is difficult to be entered sprue channel 3 by " U " and product and fills, various injection defect can be gone to from the product cast gate place close to gate location, the product gate defect region 5 of easy generation, thus the product appearance of producing causes defect.
As shown in Figure 2, be structural representation of the present utility model.Enter to water runner 1 by nozzle, mould sprue 2, sprue channel 3, product edge structure 4, product gate defect region 5, opaque products 6 form, described mould sprue 2 has nozzle and enter to water runner 1 and sprue channel 3, sprue channel 3 point of two tunnel enters product edge structure 4 and pours into opaque products 6, be provided with product elongated area 7 between described sprue channel 3 and product edge structure 4, molten plastic to be entered after sprue channel 3 by mould sprue 2 injection moulding to product elongated area 7.Product gate defect region 5 is provided with between opaque products 6 and product edge structure 4.
The utility model structure, enter sprue channel 3 place at molten plastic and extend to product elongated area 7, characteristic direction along product is mobile in the other direction toward product by gate location, essence is that defective locations is moved to product elongated area 7, can cut 7 after injection moulding, (as rear without to interfere or outward appearance be can't see and can be removed in assembled) thoroughly can solve the problem that product gate defect brings, and improves product percent of pass, thus reduces costs.Extend product cast gate place structure and do not affect outward appearance.
The difference of Fig. 1 and Fig. 2 is: Fig. 2 adds product elongated area 7 and improves the structure of sprue channel 3 of product, mould sprue 2 and sprue channel 3 relative position are optimized, effect is that product cast gate rear and front end increases cold burden interstitital texture, prevent injection defect from directly entering product surface by cast gate, no matter debug with mould structure still from becoming originally from injection parameters, substantially increase the adjustable extent of parameter, reduce the maintenance that product defects brings mould gate place, the waste of plastic material, inherently solves product cast gate place defect problem.
Claims (2)
1. a moulding mould gate structure, enter to water runner (1) by nozzle, mould sprue (2), sprue channel (3), product edge structure (4), product gate defect region (5), opaque products (6) forms, described mould sprue (2) has nozzle and enter to water runner (1) and sprue channel (3), sprue channel (3) point two tunnel symmetries enter product edge structure (4) and pour into opaque products (6), it is characterized in that: between described sprue channel (3) and product edge structure (4), be provided with product elongated area (7), make molten plastic enter sprue channel (3) and pass through mould sprue (2) injection moulding afterwards to product elongated area (7).
2. a kind of moulding mould gate structure according to claim 1, is characterized in that: be provided with product gate defect region (5) between described opaque products (6) and product edge structure (4).
