Abstract
The invention discloses a latent type flat bottom side gate used on an injection mold. The latent type flat bottom side gate is arranged in a water gap push plate and comprises a main rubber which communicates with a straight sub-runner; the straight sub-runner communicates with an inclined sub-runner arranged with an inclined angle; a flat bottom is arranged at the bottom of the inclined sub-runner; a glue inlet is formed in the lateral angle side of the flat bottom and communicates with a clamping hoop inner mold cavity; and a side cutting port is formed in the glue inlet. According to the latent type flat bottom side gate used on the injection mold, by arranging the flat bottom side gate, as experimented many times by technical staff, gate marks hardly exist on a plastic part product, shearing is quite complete, gate powder does not appear either, and the produced product is quite high in product quality.
Description
Technical field
The present invention relates to a kind of sub marine gate on injection mold, relate in particular to one
Plant the flat side gate of submarine on injection mold.
Background technology
Sub marine gate enter glue be on injection mold modal enter one of glue mode, but at present
Sub marine gate of the prior art, great majority are to lead directly to into glue, cast gate ovalize and big,
Remaining in the vestige in plastic product obvious, the most easily there is cast gate powder in plastic product.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of submarine on injection mold
Flat side gate, with overcome the plastic product produced in prior art exist gate vestiges,
The obvious mass defect of cast gate powder.
For reaching above-mentioned purpose, the present invention provides a kind of submarine on injection mold flat
Side gate, the flat side gate of described submarine is located in stripper plate；The flat limit of described submarine
Cast gate includes sprue, and described sprue connects straight runner, and described straight runner connects in one
The oblique runner that oblique angle is arranged, the bottom of described oblique runner is provided with flat, described flat
Side angle limit has glue-feeder, and this glue-feeder connection clip inside cavity, described glue-feeder is provided with to be cut
Limit mouth.
Preferably, in 45 ° of angles between described oblique runner and described straight runner.
Preferably, the descending gradually constriction of the passage of described oblique runner.
Preferably, described glue-feeder is located at the middle part of clip inside cavity.
Preferably, the size of described glue-feeder is the half of narrow passage of oblique runner.
Compared with prior art, the invention has the beneficial effects as follows by arranging flat side gate, warp
Technical staff's test of many times, the cast gate trace in plastic product almost without, shear the cleanest,
Also not having the appearance of cast gate powder, the product quality produced is the highest.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is made the most in detail
Describe.Following example are used for illustrating the present invention, but are not limited to the scope of the present invention.
The flat side gate of submarine on injection mold 13 such as Fig. 1,2,3 of the present invention
Shown in, the flat side gate of described submarine 1 is located in stripper plate 2；Described submarine is flat
Side gate 1 includes that sprue 3, described sprue 3 connect straight runner 4, described straight shunting
Road 4 connects the oblique runner 5 arranged in 45 ° of oblique angles, the passage 10 of described oblique runner 5
Descending gradually constriction.The bottom of described oblique runner 5 is provided with flat 6, described flat
The side angle limit of 6 has glue-feeder 7, and this glue-feeder 7 connects clip inside cavity 8, described in enter glue
Mouth 7 is located at the middle part 11 of clip inside cavity 8.Described glue-feeder 7 is provided with trimming mouth 9.Institute
State the half of the narrow passage 12 that size is oblique runner 5 of glue-feeder 7.
When the present invention uses, injection mold is fixed on injection machine；Injection molding matched moulds, thing
Material injection first passes around on the sprue bushing 16 being provided with between top clamping plate 14 and stripper plate 15,
Material on sprue bushing 16 flows into sprue 3 again, and sprue 3 flows into straight runner 4, directly shunts
Road flows into oblique runner 5, enters clip inside cavity 8 finally by glue-feeder 7.
The present invention is by arranging flat side gate, through technical staff's test of many times, in plastic product
Cast gate trace almost without, shear the cleanest, also there is no the appearance of cast gate powder, produce
Product quality out is the highest.
The above is only the preferred embodiment of the present invention, it is noted that lead for this technology
For the those of ordinary skill in territory, on the premise of without departing from the technology of the present invention principle, it is also possible to
Making some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
