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 Small in size, assembly is simple, and manufacturing cost is low, is designed by oblique top, helps to carry out fast demoulding, high production efficiency, production Injecting products are high-quality.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new Type.Various modifications to these embodiments will be readily apparent to those skilled in the art, and determine herein The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause This, the present invention will not be limited to the embodiments shown herein, and is to fit to and principles disclosed herein The widest scope consistent with features of novelty.
