Abstract
The utility model discloses an injection mould which comprises a front mould and a rear mould. The front mould is matched with the rear mould, a front mould insert pin is arranged on the front mould, an elastic part is arranged on the front mould insert pin, an injection groove used for injection is arranged on the rear mould, and the front mould insert pin is opposite to the injection groove and can move between the front mould and the rear mould. By the aid of the elastic part structure, the front mould insert pin can automatically compensate tolerance between the front mould and the rear mould, when hardware is small in size, the front mould insert pin automatically compensates forwardly under the force of the elastic part, when the hardware is large in size, the front mould insert pin compensates backwardly under the force of the elastic part, and finally the hardware is fully compensated by around +/-0.2mm tolerance, and accordingly the front mould insert pin is guaranteed to be capable of penetrating a penetrating face of the hardware, requirements of qualified products are met, rate of defective products is lowered, and manufacturing cost is lowered.
Description
Technical field
The utility model relates to and is used for the injection moulding tool that handware is produced, and relates in particular to a kind of injection mold.
Background technology
At present, handware need just be put into mold cavity before the mold injection and carry out the injection moulding plastic cement again, and handware is to be in ± 0.2mm scope by the tolerance that Sheet Metal Forming Technology is accomplished before this; The existence of handware tolerance and having caused: when the handware size is less than normal; Fixedly pin bumps less than bumping the face of wearing, and finally causes handware that peak is arranged, and the handware size is when bigger than normal; Again easily fixedly pin damage by pressure; In the process of actual injection moulding, there is the existence of above-mentioned two kinds of situation to have a strong impact on the quality of product, increases manufacturing cost, cause the high situation of the inferior rate of product.
This shows that prior art needs further improvement and develops.
The utility model content
The utility model provides a kind of injection mold for solving above-mentioned defective of the prior art, to reduce the inferior rate of product, reduces manufacturing cost.
For solving the problems of the technologies described above, the utility model scheme comprises:
A kind of injection mold, it comprises front mold and back mould, front mold is suitable with the back mould; Wherein, Front mold is provided with the front mold pin, and this front mold pin is provided with elastomeric element, back mould be provided with one be used for injection moulding injection slot; The front mold pin can move between front mold and back mould over against this injection slot.
Described injection mold, wherein, above-mentioned elastomeric element is a spring.
Described injection mold, wherein, above-mentioned front mold fastens the injection mold that is square with the back mould.
Described injection mold, wherein, above-mentioned front mold is provided with the pin hanging platform, and the front mold pin is arranged on this pin hanging platform, is reserved with the gap of 0.5mm between this pin hanging platform and the front mold.
A kind of injection mold that the utility model provides adopts the frame mode of elastomeric element, makes the front mold pin can be at front mold and back tolerance balancing automatically between the mould; When the handware size is less than normal, the front mold pin under the active force of elastomeric element automatically to precompensation, when the handware size is bigger than normal; The front mold pin under the elastomeric element active force to post-compensation; Finally reach the tolerance of full remuneration handware ± 0.2mm, thereby guaranteed that the front mold pin can bump the face of wearing that bumps of wearing handware, and reaches the qualified products requirement; Reduce the inferior rate of product, reduced manufacturing cost.
Description of drawings
Fig. 1 is the cross-sectional view of injection mold in the utility model;
Fig. 2 is the perspective view of injection mold in the utility model.
The specific embodiment
The utility model provides a kind of injection mold, for purpose, technical scheme and the advantage that makes the utility model is clearer, clear and definite, below will combine accompanying drawing and embodiment, to the utility model further explain.
The utility model provides a kind of injection mold, and like Fig. 1 and shown in Figure 2, it comprises front mold 1 and back mould 2; Front mold 1 is suitable with back mould 2; And front mold 1 is provided with front mold pin 3, and this front mold pin 3 is provided with elastomeric element 6, back mould 2 be provided with one be used for injection moulding injection slot 4; Front mold pin 3 can move between front mold 1 and back mould 2 over against this injection slot 4.When the handware size was less than normal, automatically to precompensation, when the handware size was bigger than normal, front mold pin 3 to post-compensation, had reduced the inferior rate of product to front mold pin 3 under the elastomeric element active force, reduced manufacturing cost under the active force of elastomeric element.
Further, above-mentioned elastomeric element 6 is a spring, the obvious other technologies forms such as shell fragment of also can adopting.And front mold 1 fastens the injection mold that is square with back mould 2, and is as shown in Figure 2.
Further, front mold 1 is provided with pin hanging platform 5, and front mold pin 3 is arranged on this pin hanging platform 5, is reserved with the gap of 0.5mm between this pin hanging platform 5 and the front mold 1.
Certainly; Above-mentioned explanation is not to be the restriction to the utility model; The utility model also be not limited in above-mentioned for example, variation, remodeling, interpolation or replacement that the technical staff in present technique field is made in the essential scope of the utility model also should belong to the protection domain of the utility model.
