Description
Technical field
The present invention relates to a kind of injection mold for being used to produce grid product (such as automobile grills).
Background technology
Cast gate is typically located at product external surfaces by the injection mold for being presently used for producing the grid products such as automobile grills, this
Sample, the outer surface of product just has injection point, and then the outward appearance of audio and video products；If setting cast gate in the side of product, use
The mode of glue is entered in side, then being molded by the product come needs artificial trimming, and material handle is sheared off from product, thus dropped significantly
Low production efficiency, and finished product rate is not also high
The content of the invention
The technical problem to be solved in the present invention, which is to provide a kind of product external surfaces, does not have injection point, without manually trimming production
The injection mold of product.
The technical scheme is that, the present invention includes quiet mould and dynamic model, and the dynamic model is provided with sliding block and for limiting cunning
The limited block of the sliding distance of block, the sliding block is provided with runner, cast gate I, the liftout attachment for ejecting material handle；The sliding block with
Dynamic model is slidably connected, and the limited block is fixedly connected with dynamic model；The runner is communicated with cast gate I, the runner also with quiet mould
Sprue is communicated；The cast gate I is communicated with core wall；The liftout attachment is arranged in sliding block, and the item goes out the ejection of device
Mouth is communicated with runner.
After said structure, the present invention compared with prior art, with advantages below：Injection mold of the present invention is provided with
Cast gate I, and the cast gate I communicates with core wall, that is to say, that and the cast gate I is located at product inwall, in this manner it is possible to
Fundamentally product external surfaces are avoided to have injection point, from the beautiful outward appearance for improving product；Because cast gate I has been located at the sliding block
On, when sliding block is slided, cast gate I- will be driven to play motion, so, the material handle connected together with product will be pulled off and with
Sliding block is moved together, and then the liftout attachment on sliding block will expect that handle is ejected from sliding block, meanwhile, product is on the top of the thimble of dynamic model
Action is ejected under using from dynamic model, so, just without manually trimming product, and then improves production efficiency.
As an improvement, the sliding block is symmetrical provided with cast gate II, cast gate II and cast gate I, the cast gate II and runner
Communicate, so, expect handle left and right uniform force in device ejection process is ejected, make material motion of handle steady, be conducive to that handle will be expected
Smoothly ejected from sliding block.
As a further improvement, the place of being slidably connected of the sliding block and dynamic model is provided with wearing plate, so, can effectively it subtract
The abrasion of few sliding block and dynamic model, and the slip of sliding block is more flexible.
As a further improvement, the liftout attachment by briquetting, stage clip, can offset or separate with a thimble of dynamic model
Push rod is constituted：The push rod is provided with the transverse annular projection that can offset or separate with briquetting, and the transverse annular projection is by item
Bar is divided into upper and lower part, and superposed one end of the rod is ejection end, and the ejection end is located at the ejection of liftout attachment
Mouthful；The compression spring sleeve is on the top of push rod, top and the sliding block sliding fit of the push rod；One end of the stage clip and sliding block phase
Support, the other end and the transverse annular projection of the stage clip offset；The briquetting is provided with the bottom slide fit of through hole, the through hole and push rod
Close；The briquetting is mounted by means of bolts on sliding block；So, when a thimble of the push rod and dynamic model offsets, institute
State push rod and rest against thimble and push to realize that ejection is acted, just independent power need not be set for the liftout attachment,
So as to simplify the structure of injection mold of the present invention, cost is saved.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
Injection mold of the present invention, it includes quiet mould 1 and work(mould 2, and the dynamic model 2 is provided with sliding block 3 and for limiting sliding block 3
The limited block 4 of sliding distance, the sliding block 3 is provided with runner 5, cast gate I6, the liftout attachment for item discharging handle 15：The sliding block
3 are slidably connected with dynamic model 2, and the limited block 4 is bolted to connection with dynamic model 2；The runner 5 is communicated with cast gate I6, institute
Sprue 7 of the runner 5 also with quiet mould 1 is stated to communicate；The cast gate I6 is communicated with core wall 17, that is to say, that described cast gate I6
At product inwall；The liftout attachment is arranged in sliding block 3, and the item outlet 8 of the liftout attachment is communicated with runner 5.It is described
Quiet mould l is provided with hot mouth 19.Concrete structure is as shown in figure l or 3 or 4.
The sliding block 3 is symmetrical provided with cast gate II12, cast gate II12 and cast gate I6, the cast gate II12 and runner 5
