A side-cutting die

Abstract

This utility model discloses a side-cutting mold, relating to the field of mold technology, including an upper mold, a lower mold, and a guide block. A placement groove is formed at the center of one end of the lower mold along its length on the side wall near the upper mold. A side-cutting mechanism is provided within the placement groove. The side-cutting mechanism includes a support block fixed at the center of the placement groove along the length of the lower mold. Identical sliders slide horizontally on both sides of the bottom end of the support block along the width of the lower mold. The top of the side wall where the two sliders are close to each other is an inclined surface. In this utility model, a wedge block simultaneously pushes the two sliders towards the center during mold closing, causing the two cutting blades to simultaneously punch the material. The design of simultaneous side-cutting on both sides makes the mold more evenly stressed during punching, reducing vibration and displacement caused by uneven stress, improving the stability and reliability of the mold, and helping to reduce burrs and other defects in the material during cutting.

Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a side-cutting mold. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). In industrial production, pressure is applied by a press to cause the material to undergo plastic deformation or separation within the die, thereby obtaining parts with the required shape, size, and performance. Stamping dies are indispensable process equipment in stamping production. They come in various structural forms and can be classified according to the nature of the process, such as blanking dies, bending dies, drawing dies, and forming dies; and according to the degree of process combination, they can be classified as single-operation dies, compound dies, and progressive dies.

[0003] With the accelerating trend of product miniaturization and precision, the manufacturing industry has put forward more stringent requirements for the performance and processing quality of molds. Under this background, traditional single-process molds have gradually exposed many shortcomings that cannot meet the needs of modern production. Since they can usually only complete one stamping process at a time, the processing of complex parts requires multiple processes, multiple clamping and positioning to complete, resulting in a cumbersome production process and a long production cycle. In particular, in the side cutting process, when the blanking force is concentrated on one side during a single unidirectional side cutting, the material is prone to uneven deformation when under stress, resulting in a tilted blanking cut and defects such as burrs.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide a side-cutting mold to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a side-cutting mold, including an upper mold, a lower mold, and a guide block. A placement groove is formed at the center of one end of the lower mold along its length on the side wall near the upper mold. A side-cutting mechanism is provided within the placement groove. The side-cutting structure includes:

[0007] The support block is fixed in the center of the lower mold along the length of the placement groove. The bottom end of the support block has two horizontally sliding sliders with the same structure on both sides along the width of the lower mold. The top of the side wall of the two sliders that are close to each other is inclined, and the top of the side wall of the two sliders that are far apart from each other is fixed with a horizontal cutting blade. The top of the side wall of the two sliders that are close to each other slides against the same vertically set wedge block. The wedge block has inclined sides on both sides along the width of the support block at the end of the wedge block that is close to the support block. The wedge block is fixed on the side wall of the upper mold that is close to the lower mold.

[0008] Furthermore, a vertically penetrating sliding channel is provided at the top of the support block. The wedge block is slidably adapted to the sliding channel. Both ends of the support block along the length of the lower mold are detachably connected to a fixing block. The fixing block is set in the storage groove. The two fixing blocks are slidably abutted against each other on both sides along the width of the upper mold on the side where they are close to each other. The two fixing blocks are respectively fixed to the side wall of the two sliders that are far apart from each other.

[0009] Furthermore, on the side wall of the two fixed blocks 2 that are close to each other, horizontal sliding channels 2 are provided at both ends along the length of the slider. The two fixed blocks 2 have the same horizontal guide rod sliding in the sliding channels 2 located in the same plane. The two ends of the guide rod are respectively fixed to the inner wall of the storage groove. On the side wall of the two fixed blocks 2 that are close to each other, horizontal sliding channels 3 are provided at both ends along the length of the slider. The sliding channels 3 are set away from the sliding channels 2. A reset spring is provided in the sliding channels 3. One end of the reset spring is fixed to the inner wall of the storage groove, and the other end is fixed to the opening of the sliding channels 3.

[0010] Furthermore, the upper mold has vertically penetrating guide holes 1 at each of the four corners of its side wall near the lower mold, and the lower mold has vertically penetrating guide holes 2 at each of the four corners of its side wall near the upper mold. The four guide holes 1 and 2 correspond one-to-one and are coaxially connected. The guide block is fixed on the side wall of the lower mold near the upper mold, located on both sides of the placement groove along the width direction of the lower mold. The length direction of the guide block is parallel to the length direction of the lower mold. The upper mold has horizontally penetrating clearance grooves on the side wall near the lower mold corresponding to the position of the guide block.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By using wedge blocks to simultaneously push two sliders towards the center during the mold closing process, the two cutting blades can simultaneously punch the material. The design of simultaneous side cutting on both sides makes the mold more evenly stressed during the punching process, reducing the vibration and displacement of the mold caused by uneven stress, improving the stability and reliability of the mold, and helping to reduce defects such as burrs that occur when cutting the material.

[0013] 2. This mold can complete the punching work on both sides simultaneously in one mold closing process. Compared with the traditional single-process mold that requires multiple clamping and positioning to complete similar processing, it greatly shortens the production cycle and improves production efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see the appendix Figure 1 To be continued Figure 6 This utility model provides a side-cutting mold, comprising an upper mold 10, a lower mold 11, and a guide block 12. A storage groove is formed at the center of one end of the lower mold 11 along its length on a side wall near the upper mold 10. A side-cutting mechanism is provided within the storage groove. The side-cutting structure includes:

[0025] The support block 21 is fixed at the center of the lower mold 11 along the length direction inside the storage groove. The bottom end of the support block 21 has two horizontally sliding sliders 24 with the same structure on both sides along the width direction of the lower mold 11. The top of the side wall of the two sliders 24 that are close to each other is inclined. The top of the side wall of the two sliders 24 that are far apart from each other is fixed with a horizontal cutting blade 25. The top of the side wall of the two sliders 24 that are close to each other slides and abuts against the same vertically arranged wedge block 20. The wedge block 20 has inclined sides along the width direction of the support block 21 at the end of the wedge block 20. The wedge block 20 is fixed on the side wall of the upper mold 10 that is close to the lower mold 11.

[0026] The top of the support block 21 has a vertically penetrating sliding channel 1. The wedge block 20 is slidably adapted to the sliding channel 1. Both ends of the support block 21 along the length direction of the lower mold 11 can be detachably connected to a fixing block 22. The fixing block 22 is set in the storage groove.

[0027] Two fixing blocks 22 are slidably abutted against each other on both sides of the upper mold 10 along the width direction. The two fixing blocks 23 are respectively fixed on the side wall of the two sliders 24 that are far apart. The two fixing blocks 23 are provided with horizontal sliding channels 2 at both ends of the side wall of the two fixing blocks 23 that are close to each other along the length direction of the sliders 24. The two fixing blocks 23 are slidably guided by the same horizontal guide rod 27 in the sliding channel 2 on the same plane. The two ends of the guide rod 27 are respectively fixed to the inner wall of the storage groove.

[0028] It should be noted that multiple stamping cutters are arranged along the length of the upper die 10 at the center of one side wall near the lower die 11, each performing different types of stamping operations on the material. This means that... Figure 1 and Figure 5 The structure shown in the image shows that the material goes through multiple stamping processes to the side cutting process and subsequent processes, thus realizing assembly line operation.

[0029] It is understandable that the same vertical guide post is slidably arranged inside the coaxial guide hole 101 and guide hole 111. The stamping drive assembly is arranged on the side of the upper die 10 away from the lower die 11, which will not be described in detail here.

[0030] In the initial state, the upper mold 10 and the lower mold 11 are separated. At this time, under the elastic force of the reset spring 26, the slider 24 is in a position close to the center of the support block 21, and the cutting blade 25 is also in a position close to the middle, leaving space for the material to be processed. The guide hole 101 and the guide hole 211 are coaxial but separated. The material to be processed is placed in a suitable position above the placement groove of the lower mold 11 to ensure the accurate position of the material for subsequent side cutting processing.

[0031] Please see the appendix Figure 1 To be continued Figure 6 The present invention provides a technical solution: on the side wall of the two fixed blocks 23 that are close to each other, there are horizontal sliding channels 3 at both ends along the length direction of the slider 24. The sliding channels 3 are set away from the sliding channels 2. A reset spring 26 is set in the sliding channels 3. One end of the reset spring 26 is fixed to the inner wall of the storage groove, and the other end is fixed to the opening of the sliding channels 3.

[0032] The upper mold 10 has vertically penetrating guide holes 101 at each of the four corners of the side wall near the lower mold 11, and the lower mold 11 has vertically penetrating guide holes 111 at each of the four corners of the side wall near the upper mold 10. The four guide holes 101 and the four guide holes 111 are one-to-one and are coaxially connected.

[0033] The guide block 12 is fixed on the side wall of the lower mold 11 near the upper mold 10, located on both sides of the placement groove along the width direction of the lower mold 11. The length direction of the guide block 12 is parallel to the length direction of the lower mold 11. A horizontal through groove 102 is provided on the side wall of the upper mold 10 near the lower mold 11 corresponding to the position of the guide block 12.

[0034] It should be noted that the guide block 12 is used to limit and guide the material, further ensuring the stability of the material during stamping;

[0035] When the mold is closed, the wedge block 20 is first inserted into the sliding channel 1, and its end slides against the inclined surface of the end of the slider 24, thereby forcing the slider 24 to slide and driving the cutting blade 25 to move synchronously for synchronous side cutting. During this period, the reset spring 26 stores force, the guide rod 27 is used to guide the slider 24 to ensure sliding stability, and the clearance groove 102 is used to prevent the guide block 12 from causing obstruction when the mold is closed.

[0036] Working principle:

[0037] In the initial state, the upper mold 10 and the lower mold 11 are separated. The slider 24 is close to the center of the support block 21 under the elastic force of the reset spring 26. The cutting blade 25 is also in the inner position, leaving space for material feeding. After the material to be processed is placed in the appropriate position of the placement groove of the lower mold 11, the stamping drive assembly causes the upper mold 10 to move down. The guide hole 101 and the guide hole 211 cooperate to guide. At the same time, the guide block 12 enters the relief groove 102 to prevent obstruction.

[0038] When the mold is closed, the wedge block 20 is inserted into the sliding channel of the support block 21, and its inclined surface abuts against the inclined surface of the slider 24, forcing the slider 24 to slide horizontally along the guide rod 27, driving the cutting blade 25 to perform side cutting. The reset spring 26 stores force to assist in subsequent reset. When the mold is opened, the upper mold 10 moves upward, the wedge block 20 disengages, the reset spring 26 pushes the slider 24 to reset, and the cutting blade 25 returns to its initial position. The finished product can then be removed for the next processing.
