Abstract
The utility model discloses an injection mould comprising a fixed mould, a movable mould matched with the fixed mould, a mold cavity, a mold core and a slider arranged on the movable die, wherein the mold cavity and the mold core are respectively and fixedly assembled on the fixed mould and the movable mould, the slider is located between the mold core and the mold cavity and is connected with a working rod of an oil cylinder, and the slider can drive the mold core to move. After a product is molded through injection, a pitched roof releases the locking force to the slider under the mechanical action of mould opening, the oil cylinder starts working to drive the slider to separate from the mold cavity, the slider drives the mold core to separate from the mold cavity, so that the external force required for pulling out the mold core is reduced, and a product can be prevented from being damaged due to unstable external force. After the mold core is separated from the mold cavity, a product obtained through injection molding is separated from the mold core either and then is completely ejected out of the mold cavity through a top block, so that the piece taking work is completed. According to the utility model, the mold core is firstly pulled out before mould opening, so that the demoulding stability is increased, the production period is shortened and the injection molding cost is reduced.
Description
Technical field
The utility model relates to the injection moulding field, particularly a kind of injection mold.
Background technology
Injection mo(u)lding is that a large amount of a kind of modes of production of using are gone up in industry at present, and injection mold is to use a kind of very widely mould in the present commercial production, mainly is made up of running gate system, cooling system, ejection system three big systems; When concrete injection moulding, product is ejected die cavity, again the core in the product is extracted; Extract core and need very big external force; As in extracting the process of core, when the external force that acts on product is not steady, be prone to make product to be damaged; Make the injection moulding failure, bring a no small difficult problem for whole Shooting Technique.And, take push pedal to eject scheme mostly for the long cylinder product of product, and cause die shape than higher, the injection moulding board is bigger to using, and production cost is higher.
Therefore, how addressing the above problem is the technical problem that needs to be resolved hurrily in the industry.
Summary of the invention
The main purpose of the utility model provides a kind of injection mold simple in structure, is intended to improve the demoulding stability of injection mold, shortens the production cycle, reduces injection machine and uses tonnage, reduces the injection moulding cost.
The utility model proposes a kind of injection mold; Comprise cover half, the dynamic model that cooperates with said cover half, fixedly be assemblied in die cavity, core on said cover half, the dynamic model respectively; Comprise that also one is installed in the slide block on the said dynamic model; Said slide block and is connected with the working beam of an oil cylinder between said core and die cavity.
Preferably, also comprise and pass the oblique top that said mold panel is used to pin said slide block.
Preferably, comprise that also one is used for the jacking block that the product with injection mo(u)lding ejects, said jacking block is positioned at the side of said mould, and fixes with a release link screw.
Preferably, the upper surface at said jacking block is provided with the one stroke switch.
Preferably, said oil cylinder is positioned at an end of said jacking block.
Preferably, be provided with a guiding briquetting in said slide block both sides.
The slide block of the utility model injection mold is installed on the dynamic model, and is arranged between said core and the die cavity, and slide block can drive the core motion.After the product injection mo(u)lding; The said sealed power of removing under the die sinking mechanism said slide block that tiltedly withstands on, oil cylinder is started working, and drives slide block and breaks away from die cavity; Slide block drives core and breaks away from die cavity; Reduced and extracted the required external force of core, and can avoid the destruction of steadily product not being caused, reduced the injection moulding mortality because of external force.After core broke away from die cavity, the product of injection mo(u)lding had also just broken away from core, and then ejected die cavity fully by the product that jacking block will break away from core, accomplished pickup work.The utility model was extracted core earlier out before die sinking, can improve the stability of the demoulding, shortened the production cycle, reduced injection machine and used tonnage, reduced the injection moulding cost.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model injection mold;
Fig. 2 is the cutaway view of Fig. 1.
The realization of the utility model purpose, functional characteristics and advantage will combine embodiment, further specify with reference to accompanying drawing.
The specific embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See figures.1.and.2; One embodiment of the injection mold of the utility model is proposed; Comprise cover half 20, the dynamic model that cooperates with said cover half 20, fixedly be assemblied in die cavity, core on said cover half 20, the dynamic model respectively, also comprise a slide block, oil cylinder 10, tiltedly push up 30 and jacking block 40.Said slide block is installed on the said dynamic model, and slide block and is connected with the working beam of oil cylinder 10 between said core and die cavity.Be provided with a guiding briquetting 50 in said slide block both sides.Tiltedly top 30 is fixed on the panel of said mould, and passes the panel of said mould, is used for slide block is pinned, and under the mechanism of injection mold die sinking, can remove the sealed power to slide block.Said jacking block 40 is used for the product of injection mo(u)lding is ejected, and jacking block 40 is positioned at the side of said mould, and fixes with a release link screw.Upper surface at said jacking block 40 is provided with one stroke switch 401.Said oil cylinder 10 is positioned at an end of said jacking block 40, and after oil cylinder 10 work, the working beam of oil cylinder 10 drives slide block movement.
Because slide block is installed on the dynamic model, and is arranged between said core and the die cavity, can drive the core motion during slide block movement.After the product injection mo(u)lding; The sealed power to said slide block is removed on said oblique top 30 under the die sinking mechanism; Oil cylinder 10 is started working, and drives slide block and breaks away from die cavity along guiding briquetting 50, and slide block just drives core and breaks away from die cavity; Reduced and extracted the required external force of core, and can avoid the destruction of steadily product not being caused because of external force.The working beam of oil cylinder 10 drives slide block disengaging die cavity to be stopped after touching travel switch 401, and at this moment, the product of injection mo(u)lding has also just broken away from core, but does not also separate fully with die cavity.After touching travel switch 401, jacking block 40 is held the slide block that contacts with travel switch 401, begins slide block is ejected; Make slide block separate and hold the product of moulding with dynamic model; Under the effect of jacking block 40, slide block is held product and is made product break away from die cavity fully, accomplishes pickup work.The utility model was extracted core earlier out before die sinking, can improve the stability of the demoulding, shortened the production cycle, reduced injection machine and used tonnage, reduced the injection moulding cost.
The above is merely the preferred embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure transformation that utilizes the utility model specification and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
