Abstract
The utility model discloses an injection mold which comprises an upper mold, a lower mold matched with the upper mold and an ejection balancing mechanism arranged between the upper mold and the lower mold, wherein a rest balancing plate is arranged inside the ejection balancing mechanism; a middle edge guide pillar is arranged on the rest balancing plate; the bottom of the middle edge guide pillar is placed on the lower mold; the top part of the middle edge guide pillar is placed on the upper die; a rest thimble is arranged on the rest balancing plate; and the top part of the rest balancing plate is placed on the upper mold. The ejection balancing mechanism is arranged in the injection mold, so that the product ejection effect is good, the structure is simple, the production cost is reduced, and the success rate of an injection product is improved.
Description
Technical field
The utility model belongs to technical field of mold, particularly a kind of injection mold.
Background technology
Mould represents the development level of industrial age, and now the range of application of plastic mould product has become our the requisite part of living.In the plastic mould field, in the situation of the comparatively complicated plastic product of forming shape, during the plastic product demoulding, some part of product is easy to because be out of shape by brute force.
When concrete injection moulding, for some special products, such as the product pockety of thimble when product ejects, in the process that ejects, because the thimble ranking is inhomogeneous, ejecting of each position of product is subjected to force unbalance, when the external force that acts on ejecting mechanism is not steady, makes easily thimble flexural deformation, thereby product is damaged, make the injection moulding failure, bring a no small difficult problem for whole Shooting Technique.
The utility model content
In order to solve the problem of above-mentioned prior art, the purpose of this utility model is that it is effective to provide a kind of product to eject, injection mold simple in structure, the success rate of attenuating production cost and raising injecting products.
In order to achieve the above object, the technical solution of the utility model is, a kind of injection mold, comprise the counterdie that patrix cooperates with patrix and be arranged on patrix and counterdie between eject balanced controls, eject balanced controls inside and be provided with the balance plate that resets, the balance plate that resets is provided with middle department limit guide pillar, and places counterdie bottom the middle department limit guide pillar, and the top places patrix; The balance plate that resets also is provided with the thimble that resets, and the thimble bottom that resets places the balance plate that resets, and its top places patrix.By cooperating of middle department limit guide pillar and reset thimble and upper die and lower die, can be well the fixing position of upper die and lower die, and can fast product be ejected, of the present utility model simple in structure, lower greatly production cost and improve the success rate of injecting products.
As further improvement of the utility model, patrix is provided with the straight flange guide pillar, and the straight flange guide pillar is arranged in the first guide pillar groove, and counterdie is provided with the second guide pillar groove that mates with the straight flange guide pillar simultaneously.
As further improvement of the utility model, the first guide pillar groove internal edges is along being provided with the department top; The second guide pillar groove internal edges is provided with holder department along top, the bottom is provided with pipe department.Holder department, Si Ding and pipe department can both provide protective effect for the straight flange guide pillar, prevent its wearing and tearing.
As further improvement of the utility model, patrix and counterdie inside are provided with screw, fix its internal structure.
As further improvement of the utility model, middle department limit guide column sleeve is equipped with middle holder department.Middle holder department can provide protective effect for middle department limit guide column sleeve, prevents its wearing and tearing.
As further improvement of the utility model, patrix is connected by the pipe nail with the counterdie two ends.
The beneficial effects of the utility model are, construct a kind of product and eject effective, simple in structure injection mold, by ejecting cooperating of balanced controls and patrix and counterdie, make when producing, patrix and counterdie are relatively fixing, and eject effectively, lower production cost and improve the success rate of injecting products.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage are more clear, in conjunction with the following drawings, and to its further description, with reference to Fig. 1.
A kind of injection mold, comprise the counterdie 2 that patrix 1 cooperates with patrix 1 and be arranged on patrix 1 and counterdie 2 between eject balanced controls 3, eject balanced controls 3 inside and be provided with the balance plate 31 that resets, the balance plate 31 that resets is provided with middle department limit guide pillar 32, and middle department limit guide pillar 32 bottoms place counterdie 2, and the top places patrix 1; The balance plate 31 that resets also is provided with the thimble 33 that resets, and thimble 33 bottoms that reset place the balance plate 31 that resets, and its top places patrix 1.By cooperating of middle department limit guide pillar 32 and reset thimble 33 and patrix 1 and counterdie 2, can be well the fixing position of patrix 1 and counterdie 2, and can fast product be ejected, of the present utility model simple in structure, lower greatly production cost and improve the success rate of injecting products.
Patrix 1 is provided with straight flange guide pillar 11, and straight flange guide pillar 11 is arranged in the first guide pillar groove 12, and counterdie 2 is provided with the second guide pillar groove 13 that mates with straight flange guide pillar 11 simultaneously.
The first guide pillar groove 12 internal edges are along being provided with department top 121; The second guide pillar groove 13 internal edges are provided with holder department 131 along top, the bottom is provided with pipe department 132.Holder department 131, department top 121 and pipe department 132 can both provide protective effect for straight flange guide pillar 11, prevent its wearing and tearing.
Patrix 1 is provided with screw with counterdie 2 inside, fixes its internal structure.
Middle department limit guide pillar 32 is set with middle holder department 321.Middle holder department 321 can provide protective effect for middle department limit guide pillar 32 covers, prevent its wearing and tearing.
Patrix 1 is connected by the pipe nail with counterdie 2 two ends.
Method by mechanical injection moulding directly injects product with the utility model, at this moment, uses external force to promote patrix 1 and breaks away from counterdie 2; Ejector retainner plate moves upward, and along with the ejector retainner plate motion, the 33 pairs of products of thimble that reset eject; Product ejects complete, and the thimble 33 that resets is done reseting movement; Ejector retainner plate resets and puts in place, and injection moulding finishes.
The according to the above description announcement of book, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the specific embodiment that discloses and describe above the utility model is not limited to also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.In addition, although used some specific terms in this specification, these terms do not become any restriction to the utility model patent just for convenience of description.
