Detailed Description
For a better understanding of the technical content of the present utility model, specific examples are set forth below, along with the accompanying drawings.
Aspects of the utility model are described in this disclosure with reference to the drawings, in which are shown a number of illustrative embodiments. The embodiments of the present disclosure are not necessarily intended to include all aspects of the utility model. It should be understood that the various concepts and embodiments described above, as well as those described in more detail below, may be implemented in any of a number of ways, as the disclosed concepts and embodiments are not limited to any implementation. Additionally, some aspects of the disclosure may be used alone or in any suitable combination with other aspects of the disclosure.
A mold guide pin structure for facilitating stripping in connection with the examples shown in fig. 1-3, comprising: the guide pin 10, the first template 20 and the second template 30, wherein the first template 20 is provided with a first mounting hole 201 for mounting the guide pin 10, and the second template 30 is used for capping the guide pin 10 mounted in the first mounting hole 201.
The guide pin 10 is installed in the first mounting hole 201, the second template 30 is fixed on the top surface of the first template 20, the guide pin 10 in the first mounting hole 201 is pressed by the second template 30, and during punching, the guide pin 10 is inserted into the guide hole of the material belt to guide the material belt.
When the die performs material strip test stamping of new materials, the influence of material properties can possibly lead to the clearance between the punched guide hole and the guide pin not meeting the requirement, the condition of too small clearance appears, at this moment, when the die is upwards moved, the guide pin can not be separated from the guide hole, and the guide pin of the existing stamping die does not have any stripping structure, so that the condition that the test stamping material strip is pulled upwards by the guide pin to deform, and test stamping data can not be obtained is caused.
As shown in fig. 1, 2 and 3, the bottom end of the guide pin 10 is sleeved with a stripping component 40 for stripping, the bottom surface of the first template 20 is provided with a second mounting hole 202, the second mounting hole 202 and the first mounting hole 201 are coaxially arranged, the stripping component 40 is installed in the second mounting hole 202, the stripping component 40 comprises a stripping ring 42 coaxially arranged with a connecting ring 41, an elastic piece 43 is fixed between the connecting ring 41 and the stripping ring 42, the connecting ring 41 is installed in the second mounting hole 202, and the stripping ring 42 is sleeved outside the guide pin 10.
So, when upper die and lower die punching press subsides, the liftout ring 42 is promoted to the second mounting hole 202 in completely, and elastic component 43 is compressed, and liftout ring 42 and elastic component 43 can not cause the influence to the punching press, and when the upper die goes up to first template 20 and the material area break away from, elastic component 43 outwards extends, exerts decurrent thrust to the material area through liftout ring 42 for the material area breaks away from with leading the right round pin 10, avoids appearing because of the too little condition that leads to the material area to be led the right round pin 10 upwards to drag because of the fit clearance.
Further, the elastic member 43 is a compression spring, and applies downward pushing force to the ejector ring 42 through the compression spring, and the compression spring can be sleeved on the guide pin 10 during installation, so that installation space is saved.
In an alternative embodiment, the material of the ejector ring 42 is stainless steel, which is not easy to rust, so that rust pollution to the material belt is avoided.
As shown in fig. 2 and 3, the second mounting hole 202 is an internal threaded hole, the outer side of the connecting ring 41 is provided with an external thread 411, and the connecting ring 41 is in threaded connection with the second mounting hole 202 through the external thread 411, so that the assembly and disassembly are convenient.
Further, two second insertion holes 421 are formed in the ejector ring 42, and when the connecting ring 41 is installed in the second installation hole 202, a rod tool is inserted into the two second insertion holes 421, and then the stripper member 40 is integrally rotated by the tool, so that the connecting ring 41 is assembled and disassembled.
Still further, two first jacks 412 are symmetrically arranged on the connecting ring 41, the two first jacks 412 and the two second jacks 421 are coaxially arranged, and when the connecting ring 41 is installed, if the rotation resistance is too large, the rod tool can be inserted into the first jacks 412 and the second jacks 421 at the same time, so that deformation and damage of the elastic piece 43 during forced rotation are avoided.
The working principle of the utility model is as follows: when the upper die and the lower die are in punching fit, the ejector ring 42 is completely pushed into the second mounting hole 202, the elastic piece 43 is compressed, the ejector ring 42 and the elastic piece 43 cannot influence punching, when the upper die moves up to the first die plate 20 to separate from the material belt, the elastic piece 43 stretches outwards, downward pushing force is applied to the material belt through the ejector ring 42, the material belt is separated from the guide pin 10, the situation that the material belt is pulled upwards by the guide pin 10 due to too small fit clearance is avoided, the stripping part 40 is integrally detached during formal production after die debugging is completed, and the guide pin is reinstalled for use in next trial punching.
The foregoing description is only a preferred embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and any person skilled in the art, who is within the scope of the present utility model, should make equivalent substitutions or modifications according to the technical solution of the present utility model and the inventive concept thereof, and should be covered by the scope of the present utility model.
