Abstract
The utility model provides a die structure with double-lug connectors, wherein the middle part of a die body is provided with a die cavity with the double-lug connectors, the middle part of the die cavity is provided with a core part, the upper part of the core part is of a plane structure, and the upper plane of the core part is lower than a flash bridge part of the die cavity; the draft of the front wall of the core part is 7 degrees, and the upper edge of the side surface of the core part is provided with a gradually changed R round angle. The beneficial effects are as follows: the front wall drawing inclination of the core is changed from 5 degrees to 7 degrees, so that the whole core structure is more in line with the metal flow rule, the folding of a forge piece is reduced, the die stripping is convenient, the flash waste can be reduced, and the material utilization rate is improved; the structure of the flash bin part above the core part is cancelled, and the R fillet is changed from R4 to R4 to R8, so that metal can easily flow inwards, the forging is convenient to form, and the forging quality is improved; after the flash bin part is eliminated, the waste of external flash is reduced, the material utilization rate is improved, and the material consumption is reduced.
Description
Technical Field
The utility model relates to a mould field especially indicates a ears connector mould structure.
Background
The ears connector is as the important part of hydraulic support part, is the key product of my company's production, and the specification is many, and is in large quantity, but nevertheless has folding, fill not full, the demolding difficulty for a long time, and material utilization rate hangs down the scheduling problem, and later stage loose piece is reprocessed, is cleaned and grinds the task heavy, seriously influences the production plan, and the cost also remains high, and production efficiency urgently needs to promote, and the quality problem is waited to solve.
As shown in fig. 2, the bin part of the existing die structure is grooved to form a flash bin part structure 7, metal deformation easily flows to the grooved part, so that a forged piece is not easy to fill, the round corner of the forged piece is short of meat, and the quality of the forged piece is reduced; the existing forging die structure has large cut flash, so that the material utilization rate is low, and the material consumption cost is increased; the existing forging die has the advantages that the pattern drawing of the crotch part is 5 degrees, the forging piece is easy to fold, and the pattern stripping is difficult; the existing forging core part is provided with a chamfer R4, so that metal easily flows outwards, the forging forming is not facilitated, and a forging die is easily deformed.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the problem that exists among the prior art, provide a binaural connector mould structure.
The technical scheme of the utility model is realized like this:
a binaural connector mold structure, comprising: the die comprises a die body, wherein a die cavity with a double-lug connector is formed in the middle of the die body, a core part is arranged in the middle of the die cavity, the upper part of the core part is of a planar structure, and the upper plane of the core part is lower than a flash bridge part of the die cavity; the draft of the front wall of the core part is 7 degrees, and the upper edge of the side surface of the core part is provided with a gradually changed R round angle.
Further, the upper plane of the core is 2mm lower than the flash bridge of the die cavity.
Further, the R-radius of the core side upper edge is graded from R4 to R8, and R4 is graded from the core left end 1/3 to R8.
The utility model has the advantages that:
1. the front wall drawing inclination of the core is changed from 5 degrees to 7 degrees, so that the whole core structure is more in line with the metal flow rule, the folding of a forge piece is reduced, the die stripping is convenient, the flash waste can be reduced, and the material utilization rate is improved;
2. the structure of the flash bin part above the core part is cancelled, and the R fillet is changed from R4 to R4 to R8, so that metal can easily flow inwards, the forging is convenient to form, and the forging quality is improved; after the flash bin part is eliminated, the waste of external flash is reduced, the material utilization rate is improved, and the material consumption is reduced.
Drawings

fig. 2 is a schematic structural view of a conventional 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. 1-2, a die structure for a binaural connector includes: the die comprises a die body 1, wherein a die cavity 2 with a double-lug connector is formed in the middle of the die body 1, a core part 3 is arranged in the middle of the die cavity 2, the upper part of the core part 3 is of a planar structure, and the upper plane of the core part 3 is 2mm lower than a flash bridge part 6 of the die cavity 2; the draft of the front wall 4 of the core 3 is 7 deg., the upper edge of the side of the core 3 is provided with a gradual R fillet 5, the R fillet 5 is gradual from R4 to R8, and R4 is gradual from 1/3 at the left end of the core 3 to R8.
The draft angle of the front wall 4 of the core part 3 is changed from 5 degrees to 7 degrees, so that the structure of the whole core part 3 better conforms to the metal flow rule, the folding of a forge piece is reduced, the die stripping is convenient, the flash waste can be reduced, and the material utilization rate is improved.
The structure of the flash bin part above the core part 3 is cancelled, and the R fillet 5 is changed from R4 to R4 to R8, so that metal can easily flow inwards, the forging is convenient to form, and the forging quality is improved; after the flash bin part is eliminated, the waste of external flash is reduced, the material utilization rate is improved, and the material consumption is reduced.
