Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment
In conjunction with Fig. 1, Fig. 2, Fig. 3, the utility model discloses a kind of injection molds with ramp-roof structure, are mainly used for giving birth to
The cover body structure injecting products with back-off having along side are produced, die main body can be using the knot of existing fixed half and moving half cooperation
Structure mode.Mode 1, fixed mold insert 3, sliding block 2, the first thimble 5, the second thimble 7, movable pin 6 are installed on dynamic model；In cover half
Upper installation shovel.Fixed mold insert 3 is installed on mode 1.Four sliding slots are provided on mode 1, centered on fixing mold insert 3,
In cross-shaped structure.A sliding block 2 is provided in every sliding slot；The oblique guide hole 4 with shovel cooperation is provided on sliding block 2, it is sliding
Block 2 is moved along the chute by shovel.The front end of Four-slider 2 and fixed mold insert 3 constitute injection die cavities, and fixed mold insert 3 is located at injection molding
The inside of product, sliding block 2 are located at the outside of injecting products.Inclined top hole is provided on fixed mold insert 3；Activity setting in inclined top hole
There is movable pin 6.Movable pin 6 is preferably formed in below fixed mold insert 3 by S45C steel and is provided with the first thimble 5 and the second thimble
7；First thimble 5 and the second thimble 7 are vertically arranged；First thimble 5 passes through fixed mold insert 3.Second thimble 7 connects with movable pin 6
Touching, driving activity pin 6 are moved along inclined top hole.When demoulding, the first thimble 5 carries out positive jacking, movable pin 6 to injecting products
It is generally disposed at the edge of fixed mold insert 3,7 promotion activity pin 6 of the second thimble carries out oblique thimble to injecting products, makes to be molded
Occurs allowing bit space on the inside of product, for carrying out de-molding injection molded products.
For the ease of the fixed mold insert 3 of installation and replacement, fixed mold insert 3 is in boss shape structure, solid by spiral and mode 1
It is fixed.This design, fixed mold insert 3 not only facilitates processing, but also fixed mold insert 3 can be replaced, and produces to carry out different injection moldings
The production of product, flexibility is good, and replacement cost is low, helps to substantially reduce the die cost in production process.Meanwhile fixed mold insert
It is worn after 3 long-time uses, dismounting and change can be carried out, without replacing entire mold.
Movable pin 6 in the utility model is more, and different movable pins 6 can according to need that setting is different to incline
Rake angle, flexibility are good.The angle of movable pin 6 and vertical direction is preferably 3-45 °.
The action process and principle of the utility model：The utility model is all vertical due to the first thimble 5 and the second thimble 7
Setting, is jacked along the vertical direction, therefore, only needs a set of lifting body.It can be designed using conventional top board structure,
First thimble 5 and the second thimble 7 are installed on top plate, usually external mandril pushes top plate, and top plate drives 5 He of the first thimble
The movement of second thimble 7.When the utility model mold-closing injection, fixed shovel is in clamping process with cover half, promotion sliding block 2, and four
Sliding block 2 is gathered outside fixed mold insert 3, constitutes injection die cavities with fixed mold insert 3, at this point, before movable pin 6 and the first thimble 5
End and fixed 3 surface of mold insert are horizontal, then carry out product injection molding.After the completion of injection molding, when carrying out die sinking demoulding, first it is opened, sliding block 2
Under the action of shovel, move to far from fixed 3 direction of mold insert, be detached from injecting products, can be to avoid injecting products outside
The back-off of side influences demoulding；After demould, top plate is pushed by external mandril, the first thimble 5 and the second thimble 7 carry out vertical direction
Jacking, at this point, movable 6 oblique movement of pin, makes occur allowing bit space on the inside of injecting products between fixed mold insert 3, injection molding
Product is detached from fixed mold insert 3 under the jacking effect of movable pin 6 and the first thimble 5, realizes demoulding.
By above-mentioned specific embodiment, the utility model has the beneficial effects that：The utility model is simple and reasonable, mold
