Abstract
The utility model provides a back swift current connector mould, the mould includes mould and lower mould, model cavity has been seted up down on the lower mould, the front portion in model cavity is equipped with the core down, the overlap bridge in model cavity is higher than the last plane of lower mould down, overlap bridge encircles model cavity a week down, cancellation mould core position is close to model cavity part overlap bridge down, the resistance of metal to the inside flow of mould cavity has been reduced, resistance groove has still been seted up in the front portion in model cavity down, resistance groove can increase the metal resistance that flows, effectively improve the metal and flow. The beneficial effects are as follows: the flow of metal is effectively improved, a flash bridge of a part, close to the cavity, of the core part of the die is eliminated, the resistance of the metal to flow into the cavity of the die is reduced, meanwhile, a resistance step is added close to the outer part of the core part, the resistance of the metal to flow outwards is increased, and the cavity is filled with the metal more easily.
Description
Technical Field
The utility model relates to a manufacturing mould of back swift current connector especially indicates a back swift current connector mould.
Background
The back swift current connector is the standard part, and demand quantity is many, big in batches, and material utilization is low in the current mould production process, causes the material extravagant, and this forging takes shape the difficulty, has the movable part to fill not full phenomenon, needs later stage rework to repair, causes the cost to increase.
When the design of the middle core part flash structure of the backward sliding connector square head die is carried out, the structure of a forged piece and the metal flowability are not comprehensively considered, the forming is difficult, the forged piece is not easy to fill, the material utilization rate is low, the core is easy to deform, and the service life of the die is short.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the problem that exists among the prior art, provide a back swift current connector mould.
The technical scheme of the utility model is realized like this: a back slide connector die comprises: the mold comprises an upper mold and a lower mold, a lower mold cavity is formed in the lower mold, a core is arranged at the front of the lower mold cavity, a flash bridge of the lower mold cavity is higher than the upper plane of the lower mold, the flash bridge surrounds the lower mold cavity for a circle, and a resistance groove is formed in the front of the lower mold cavity.
Further, the upper plane of the core is lower than the upper plane of the flash bridge.
The utility model has the advantages that:
1. the flow of metal is effectively improved, a flash bridge of a part, close to the cavity, of the core part of the die is eliminated, the resistance of the metal to flow into the cavity of the die is reduced, meanwhile, a resistance step is added close to the outer part of the core part, the resistance of the metal to flow outwards is increased, and the cavity is filled with the metal more easily.
2. The resistance groove is added on the die, so that the metal flow resistance is increased, and the metal flow is effectively improved.
3. The material utilization rate is improved from the original 67 percent to 77.4 percent, and the production cost is reduced.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a schematic view of the structure of a lower mold
FIG. 2 is a schematic structural diagram of a conventional mold;
fig. 3 is a schematic structural view of the mold.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
As shown in fig. 1-3, a back slide connector mold comprises: the die comprises an upper die 1 and a lower die 2, a lower die cavity 3 is formed in the lower die 2, a core 4 is arranged at the front part of the lower die cavity 3, a flash bridge 5 of the lower die cavity 3 is higher than the upper plane of the lower die 2, the flash bridge 5 surrounds the lower die cavity 3 for a circle, part of the flash bridge 5, close to the lower die cavity 3, of the die core 4 is eliminated, the resistance of metal to the internal flowing of the die cavity is reduced, a resistance groove 6 is formed in the front part of the lower die cavity 3, the resistance groove 6 can increase the flowing resistance of the metal, and the flowing resistance of the metal is effectively improved.
The upper plane of the core 4 is lower than the upper plane of the flash bridge 5 to form a resistance step, and the resistance step is added near the outer part, so that the resistance of the outward flowing metal is increased, and the cavity is filled with the metal more easily.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
Claims (2)
1. A back slide connector die comprises: the mould includes mould and lower mould, has seted up down the model chamber on the lower mould, the front portion in model chamber is equipped with core, its characterized in that down: the flash bridge of the lower mold cavity is higher than the upper plane of the lower mold, the flash bridge surrounds the lower mold cavity for a circle, and the front part of the lower mold cavity is also provided with a resistance groove.
2. The rear slip joint die set forth in claim 1, wherein: the upper plane of the core is lower than the upper plane of the flash bridge.
