Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal processing, in particular to a die end cover trimming device for producing gloves. Background Art

[0002] The mold used to produce nitrile gloves includes a mold body and an end cap arranged at one end of the mold body. When producing gloves, the end cap and the mold body need to be fixed together by welding. However, in order to ensure the uniformity of the weld width when welding the end cap and the mold, the welder needs to manually adapt the end cap multiple times to achieve the best positioning effect. Therefore, this positioning method is inefficient, and the quality of positioning depends entirely on the skill level of the welder himself, and the positioning quality is not guaranteed.

[0003] Therefore, in order to improve the assembly quality of the end cap and the mold body and achieve rapid positioning of the end cap on the mold body, see the attached Figure 1 The figure shows an end cap that can be quickly positioned with the mold body. A positioning platform is stamped on one side of the end cap. During assembly, the positioning platform only needs to be placed in the mold body to achieve positioning. At the same time, a rectangular frame is opened at the center of the end cap, and a bending portion is provided on each of the two long sides of the rectangular frame.

[0004] At present, after the end cap is stamped on the stamping machine, the edge of the end cap is uneven and has many burrs due to stamping shearing. In order to ensure the quality of the weld and prevent welding deviation or undercut problems, the end cap needs to be trimmed by wire cutting or plasma cutting. However, the trimming efficiency is low when using wire cutting, and the trimming cost is greatly increased when using plasma cutting.

[0005] Therefore, the present application provides a mold end cover trimming device for producing gloves, which is used to improve the trimming efficiency and reduce the trimming cost. Utility Model Content

[0006] In view of the above technical problems, the utility model provides a mold end cover trimming device for producing gloves, which is used to solve the problems of low efficiency and high cost caused by the existing end cover trimming by wire cutting and plasma cutting.

[0007] The above technical objectives of the utility model are achieved through the following technical solutions:

[0008] A mold end cap trimming device for producing gloves, comprising a top mold and a bottom mold, a connecting seat is provided at the bottom of the bottom mold, a mounting cavity is provided in the middle of the bottom mold, a positioning block is detachably installed in the mounting cavity, and the top mold comprises a mold frame, a stamping seat is detachably installed in the mold frame, a sliding hole is provided in the middle of the stamping seat, a pressure block is provided in the sliding hole, a plurality of lifting springs are arranged in a circumferential array on one side of the pressure block close to the mold frame, an avoidance cavity is provided in the center of the pressure block, and a trimming ring is provided on the edge of the stamping seat located at the sliding hole;

[0009] A forming ring is provided at the edge of the pressing block, the forming ring faces the bottom mold direction, and the height of the forming ring is equal to the height of the positioning platform of the end cover.

[0010] Furthermore, the edge circumference array of the pressing block has a plurality of T-shaped blocks, and the punching seat is provided with T-shaped slots at positions corresponding to the T-shaped blocks, and the pressing block reciprocates along the T-shaped slots through the T-shaped blocks.

[0011] Furthermore, a discharge hole is provided around the positioning block of the bottom mold, a discharge spring is provided in the discharge hole, and one end of the discharge spring is connected to a discharge column.

[0012] Furthermore, a guide column is rectangularly arranged on the bottom mold, and a guide hole is arranged at a position of the mold frame corresponding to the guide column, and the guide hole cooperates with the guide column.

[0013] In summary, the beneficial technical effects of the utility model are:

[0014] (1) The end cap can be positioned on the bottom die by using the positioning block, and the top die can be driven downward by the punching machine. The edge of the end cap positioning platform can be extruded and shaped by the pressing block and the forming ring to improve the circularity of the positioning platform and ensure that it can be accurately positioned with the die body. At the same time, the edge of the end cap can be extruded and shaped by the trimming ring to trim the edge and remove burrs to ensure the quality of the weld. Compared with the original wire cutting trimming, it is more efficient and has a lower cost than plasma cutting trimming.

[0015] (2) The combination of the T-shaped block and the T-shaped slot not only improves the stability of the sliding of the pressing block in the punch seat, but also prevents the pressing block from falling off from the punch, thereby improving the safety of the entire top die.

[0016] (3) By using the unloading column and unloading spring, the end cover can be popped up after the top mold is raised after trimming, which makes it convenient for the staff to take the material. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The present invention will be described clearly and completely below in conjunction with the embodiments.

[0028] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0029] In the description of the embodiments, unless otherwise clearly specified and limited, the terms "disposed", "connected" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or it can be connected through an intermediate medium, or it can be a communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] See attached Figure 1The figure shows a schematic diagram of the structure of the end cover 1, wherein a positioning platform 2 is stamped on one side of the end cover 1, and the positioning platform 2 can be accurately inserted into the mold body. In order to improve the weld quality of the joint between the end cover 1 and the mold body, the edge of the end cover 1 needs to be trimmed.

[0031] See attached Figure 2-8 , shown is a mold end cap trimming device for producing gloves, comprising a top mold 4 and a bottom mold 5, specifically, the bottom of the bottom mold 5 is fixedly connected with a connecting seat 6 by bolts, and the entire bottom mold 5 is fixed to the punch press by the connecting seat 6 when in use, and a mounting cavity is opened in the middle of the bottom mold 5, and a positioning block 7 is fixed with bolts in the mounting cavity, and the positioning block 7 is used to fit with the rectangular frame on the end cap 1 to realize the positioning of the end cap 1 on the bottom mold 5;

[0032] The top die 4 includes a die frame 8. When in use, the die frame 8 is installed at the action end of the punch press, and the punch press drives the top die 4 to rise and fall relative to the bottom die 5 to achieve trimming of the end cover 1. A punch seat 9 is bolted to the die frame 8. A sliding hole is provided in the center of the punch seat 9. A trimming ring 11 is provided on the edge of the sliding hole of the punch seat 9. When in use, the top die 4 is driven to move downward by the punch press. When the top die 4 moves downward, the trimming ring 11 is just fitted on the end cover 1. The trimming ring 11 extrudes and shapes the edge of the end cover 1 to make the edge of the end cover 1 more neat. At the same time, the trimming ring 11 squeezes and removes the burrs on the edge of the end cover 1 to achieve the purpose of trimming. In addition, a pressing block 10 is provided to slide in the sliding hole of the punch seat 9. A plurality of lifting springs 13 are arranged in a circumferential array on one side of the pressing block 10 close to the die frame 8, and the other end of the lifting spring 13 abuts against the die frame. 8, a forming ring 12 is provided on the other side of the pressing block 10, and the height of the forming ring 12 is equal to the height of the positioning platform 2 of the end cover 1. An avoidance cavity 14 is opened inwardly at the center of the pressing block 10, and the avoidance cavity 14 is used to provide a holding space for the positioning block 7 to avoid interference between the top mold 4 and the positioning block 7. When trimming, the end face of the pressing block 10 is just fitted to one side of the end cover 1, and the forming ring 12 is just fitted on the positioning platform 2 to extrude and shape the edge of the positioning platform 2. As the top mold 4 continues to move downward, the end cover 1 acts in the reverse direction and the pressing block 10 shrinks inward along the sliding hole. When the top mold 4 moves upward, the pressing block 10 pops outward under the reverse action of the lifting spring 13. It can be seen that the edge of the end cover 1 is corrected by the cooperation of the top mold 4 and the bottom mold 5, thereby replacing the original trimming method, which not only improves the trimming efficiency, but also reduces the trimming cost.

[0033] At the same time, in order to prevent the pressing block 10 from falling out of the sliding hole when it rebounds outward under the action of the lifting spring 13, a plurality of T-shaped blocks 15 are provided on the edge of the pressing block 10, and a T-shaped slot 16 is opened at the position of the T-shaped block 15 on the punching seat 9. One end of the T-shaped slot 16 is closed. When the pressing block 10 retracts inward along the sliding hole, the T-shaped block 15 slides along the T-shaped slot 16. When the pressing block 10 rebounds, the closed end of the T-shaped slot 16 limits the T-shaped block 15, thereby preventing the pressing block 10 from falling off.

[0034] At the same time, in order to facilitate the removal of the trimming rear end cover 1, a discharge hole is opened around the positioning block 7 of the bottom mold 5, and a discharge spring 18 is arranged in the discharge hole. A discharge column 17 is arranged at one end of the discharge spring 18. When the trimming rear end cover 1 bounces upward under the action of the discharge column 17, it is separated from the bottom mold 5.

[0035] See attached Figure 8 As shown, the specific working principle and structure of the discharge spring 18 and the discharge column 17 are the same as those of the spring plunger in the prior art. Specifically, a connecting sleeve with an external thread is mounted on the discharge column 17 and the discharge spring 18. The discharge column 17 is extended and retracted back and forth along the connecting sleeve under the action of the discharge spring 18, and the connecting sleeve is threadedly connected to the bottom mold 5.

[0036] At the same time, in order to improve the fitting accuracy of the top mold 4 and the bottom mold 5, a guide column 19 is provided at the four corners of the connecting seat 6, and a guide hole 20 is opened at the position of the mold frame 8 corresponding to the guide column 19. The cooperation between the guide column 19 and the guide hole 20 improves the stability and fitting accuracy of the top mold 4 and the bottom mold 5.

[0037] Please refer to the attached Fig. 9 First, the end cover 1 is put on the positioning block 7 of the bottom mold 5 through the rectangular frame, and then the top mold 4 is driven downward by the punch press. As the top mold 4 continues to move downward, the pressing block 10 abuts against the side of the end cover 1. At the same time, the forming ring 12 is put on the positioning platform 2 to extrude and shape the edge of the positioning platform 2. At this time, the positioning block 7 is placed in the avoidance cavity 14. Then, the pressing block 10 retracts inward along the sliding hole under the reaction of the end cover 1. At the same time, the trimming ring 11 is put on the periphery of the end cover 1 to extrude and shape the edge to make the edge more neat. After the trimming is completed, the end cover 1 is lifted up by the unloading spring 18 and removed from the positioning block 7.

[0038] The above description is only a preferred specific implementation method of the present utility model, and does not limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
