A kind of easy Double-ejection injection mold
The utility model is related to a kind of mould, specifically a kind of easy Double-ejection injection mold, belongs to Design of Dies
Manufacturing technology field.
When product side cornice is fluted or during boss, plastic products are difficult directly to deviate from from mould, can by groove and
Boss is made on the side core drawing structures such as slide block, oblique top, and for groove or the less product of boss can also be taken ejection is forced
Existing product side cornice has small boss, it is desirable to which land area has certain deformation space when ejecting, and this product
Land area is completely dynamic in-molded.First ejecting product makes product separate with dynamic model with boss forming region, continues to eject
Product is made at boss to race deformation until product is kept completely separate with boss forming region.This structure makes product have certain deformation
Space, stress during Double-ejection at side wall boss is greatly reduced, and the damage to product is less, and it is little that this structure is applied to inner band
The product of buckle or groove such as terminal box, socket, connector etc..
If product is directly ejected, ejecting force can be greatly increased, and the side wall boss of product easily ruptures, pulls, defective products compared with
It is many；According to ramp-roof structure, due to interiors of products space it is less, oblique top and mould strength it is poor, and die cost is higher.
The content of the invention
For the problem that above-mentioned prior art is present, the utility model provides a kind of easy Double-ejection injection mold,
This simple structure, stable, knockout press is less during ejection, product side wall boss not easy fracture, pull, when greatly reducing production not
To achieve these goals, the technical solution adopted in the utility model is：A kind of injection of easy Double-ejection
Mould, including product, dynamic model, straight jacking block, thimble, pin, push pedal, it is characterised in that：Straight jacking block, thimble are arranged in dynamic model,
Pin is arranged on the lower section of straight jacking block, and push pedal is arranged on the lower section of straight jacking block and thimble, step surface and the dynamic model bottom surface of straight jacking block
Distance be 9.5MM, between straight jacking block and push pedal distance be 11MM.
Further, straight jacking block is supported to product after dynamic model and separated with dynamic model.
The beneficial effects of the utility model are：Direction setting gap, product are ejected with straight jacking block by dynamic model, push pedal respectively
Straight jacking block is supported to dynamic model stop motion after ejection dynamic model, and thimble continues ejecting product and separates with straight jacking block.This structure makes product top
There is regional area to have certain deformation space when going out, reduce local fracture when product is ejected, pull, mould structure is simple, stable
And damage of product rate is little, effectively reduces die cost and improve die life, reduce product fraction defective.
The utility model is described in further detail below in conjunction with accompanying drawing for description of the drawings.
Fig. 1 is the utility model profile.
Fig. 2 is the structural representation that straight jacking block of the present utility model props up dynamic model.
In figure：1st, product, 2. dynamic model, 3. thimble, 4. straight jacking block, the 5. push pedal of pin 6..
As depicted in figs. 1 and 2, the utility model includes straight jacking block（4）, thimble（3）, pin（5）, dynamic model（2）, push pedal
（6）And product（1）.Straight jacking block（4）, thimble（3）It is arranged on dynamic model（2）It is interior, pin（5）It is arranged on straight jacking block（4）Lower section, push away
Plate（6）It is arranged on straight jacking block（4）With thimble（3）Lower section, straight jacking block（4）Step surface and dynamic model（2）Distance be 9.5MM, directly
Jacking block（4）Bottom surface and push pedal（6）Distance is 11MM.
When product is ejected, first thimble, product move upwards 9.5MM simultaneously with straight jacking block, and now straight jacking block step surface is supported
Firmly stop moving upwards after dynamic model, product is separated with dynamic model；Thimble, product continue up ejection 11MM, product and straight jacking block point
From, then taking out product, the i.e. demoulding and complete, pin props up straight jacking block during matched moulds.
