Description

Technical Field

[0001] This utility model belongs to the technical field of mold limiting devices, specifically relating to a stamping mold limiting device. Background Technology

[0002] In existing stamping processes, dies operate under high speed and high pressure, and the relative positional accuracy between dies is crucial to product quality. Traditional limiting methods have certain shortcomings. For example, Chinese patent CN 221109602 U discloses a guide limiting device for mold stamping, including a bottom mounting plate, a top mounting plate on the top of the bottom mounting plate, symmetrical adjustment slots on the bottom mounting plate, a mounting seat inside the adjustment slot, and an adjustment bolt threaded to the mounting seat via a bearing inside the adjustment slot. The top of the top mounting plate has four through slots, and a movable block is arranged inside the through slot. The top of the movable block is threadedly connected to a first limiting sleeve and a second limiting sleeve, respectively. A guide sleeve is engaged between the first and second limiting sleeves, and the top of the movable block has a groove threadedly connected to the first and second limiting sleeves. Although this device can limit molds, its limiting stroke is limited and cannot be adjusted according to actual conditions, thus limiting its application range. Furthermore, when connecting the device to a mold, it cannot be adjusted according to the mold specifications, further narrowing the device's application range. Utility Model Content

The supporting component includes a supporting portion and multiple guiding portions. The multiple guiding portions are all fixedly connected to the top of the supporting portion perpendicular to the horizontal plane. The movable component is sleeved between the multiple guiding portions, and multiple springs are sleeved on the guiding portions. The guiding portions include N base rods, where N≥1. The top of each base rod is recessed to form a connecting groove, and the bottom of each base rod protrudes outward to form a connecting rod that matches the connecting groove.

[0020] 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.

[0021] Please see Figures 1-6 As shown, this utility model provides the following technical solution:

[0022] A stamping die limiting device includes a movable part 1 and a support part 2. The movable part 1 is located above the support part 2, and a mounting cavity for accommodating the die is formed between the movable part 1 and the support part 2. The support part 2 includes a support portion and multiple guide portions. The multiple guide portions are all fixedly connected to the top of the support portion perpendicular to the horizontal plane. The movable part 1 is sleeved between the multiple guide portions. Multiple springs 28 are sleeved on the guide portions. The guide portions include N base rods 26, where N≥1. The top of the base rods 26 is recessed to form a connecting groove 210, and the bottom of the base rods 26 is protruding to form a connecting rod 29 that matches the connecting groove 210. The top of the support portion is recessed to form a hole that matches the connecting rod 29.

[0023] With the above technical solution, before personnel use the mold, the support part is placed at the position where personnel need to place it, and then the lower part of the mold is placed above the support part, so that the lower part of the mold is connected to the support part. Then, the upper part of the mold is placed below the moving part 1, and the upper part of the mold is connected to the moving part 1. Take the required number of base rods 26, place the base rods 26 above another base rod 26, and screw the connecting rod 29 on the base rod 26 into the connecting groove 210 on the other base rod 26. Following the above steps, connect the required number of base rods 26, so that the base rods 26 are adjusted to the length required by personnel. Then connect the adjusted base rods 26 to the support part. According to personnel needs, install other adjusted base rods 26 onto the support part. Then, fit the moving part 1 between the multiple base rods 26. When personnel use the mold, the base rods 26 restrict the movement direction of the moving part 1, and the spring 28 buffers the moving part 1.

[0024] To limit the maximum movement distance of the top plate 11, such as Figures 1-4 As shown, a movable first threaded ring 27 is screwed onto the base rod 26, and the first threaded ring 27 is located above the movable part 1.

[0025] In this embodiment, when a person places the movable part 1 between multiple base rods 26, it is screwed into the base rods 26 by the first screw ring 27, thereby limiting the maximum movement distance of the top plate 11.

[0026] Specifically, in one embodiment, regarding the aforementioned support portion, as... Figures 1-4 As shown, the support part includes a base 22, and two base plates 21 are symmetrically fixedly connected to the bottom of the base 22.

[0027] In this embodiment, when personnel use the device, the base plate 21 supports the base 22, the base rod 26 is supported by the base 22, and the lower part of the mold is supported by the base 22.

[0028] Furthermore, in this utility model, regarding the aforementioned movable component 1, as follows: Figures 1-2 , Figure 5 and Figure 6 As shown, the movable component 1 includes a top plate 11, which is sleeved on the base rod 26. A connecting pipe 12 is fixedly connected to the top of the top plate 11, and a positioning screw 13 is screwed onto the circumference of the connecting pipe 12. The free end of the positioning screw 13 extends into the interior of the connecting pipe 12.

[0029] In this embodiment, before using the device, the operator inserts the telescopic end of the hydraulic press into the connecting pipe 12, rotates the positioning screw 13 on the connecting pipe 12, so that one end of the positioning screw 13 abuts against the telescopic end of the hydraulic press, thereby connecting the hydraulic press to the top plate 11, making it easier for the hydraulic press to move the top plate 11.

[0030] When the device is connected to the mold, in order to make the connection between the device and the mold more secure, such as Figures 1-6 As shown, two second limiting plates 15 are installed on the side of the top plate 11 facing the base 22, and two first limiting plates 24 are installed on the side of the base 22 facing the top plate 11. Guide rods 211 are fixedly connected to the opposite sides of the second limiting plates 15 and the first limiting plates 24. A second screw ring 212 is screwed onto the guide rod 211. Limiting rods 25 are screwed onto the two first limiting plates 24 and the two second limiting plates 15.

[0031] In this embodiment, when personnel need to connect the upper part of the mold to the top plate 11, the upper part of the mold is placed below the top plate 11, and the lower part of the mold is placed above the base 22. The limiting rods 25 on the second limiting plate 15 and the first limiting plate 24 are rotated to move the limiting rods 25 to the position required by the personnel. The guide rods 211 on the top plate 11 and the base 22 are pulled, causing the guide rods 211 to drive the second limiting plate 15 and the first limiting plate 24 to move, so that the limiting rods 25 abut against the upper part and the lower part of the mold, thereby connecting the mold with the top plate 11 and the base 22.

[0032] Furthermore, in order to further improve the tightness of the connection between the base 22 and the top plate 11 and the mold, such as... Figures 1-6 As shown, the base 22 is recessed on the side facing the top plate 11 to form a first positioning groove 23, and the top plate 11 is recessed on the side facing the base 22 to form a second positioning groove 14.

[0033] In this embodiment, when the limiting rod 25 abuts against the mold, the first positioning groove 23 and the second positioning groove 14 cooperate to make the mold more stable after installation.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
