Technical Field

[0001] This utility model relates to the field of cold heading forming mold technology, specifically a cold heading forming mold for a one-way device. Background Technology

[0002] Cold heading forming mold is a mold specifically used for the cold heading process. It is used on a cold heading machine to cut, pre-form, and form metal blanks to produce various cold-formed parts. This mold usually consists of two half molds and a set of mold cores. Through the mold closing action and the pushing of the mold cores, the metal material undergoes plastic deformation in the mold, ultimately forming the required threads, grooves, and other shapes.

[0003] The utility model patent application with publication number "CN221312352U" discloses a cold heading forming mold, including a mold body, a mold groove on the upper surface of the mold body, a demolding device on the lower surface of the mold body, and a reinforcing device on the outer surface of the mold body. In actual use, this utility model can push the cold heading bolt out of the mold to achieve rapid demolding and improve the efficiency of material handling. This utility model can provide multiple reinforcements at the joints of the mold to improve the stability of the material inside the mold during stamping.

[0004] The cold heading forming mold disclosed in the above document has the following defects: after long-term use, the forming groove inside the mold will be worn and damaged. However, the forming groove of this technical solution is opened on the mold body. Damage requires the whole mold to be replaced, which results in relatively high usage costs.

[0005] Therefore, it can be seen that the existing cold heading forming mold does not have the structure of replacing the mold independently, and it is necessary to improve the existing shortcomings and provide a cold heading forming mold for one-way devices. Utility Model Content

[0006] The purpose of this invention is to provide a cold heading die for a one-way device to solve the problems mentioned in the background art.

[0007] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0024] 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.

[0025] Please see Figure 1 - Figure 4As shown, this utility model is a cold heading forming mold for a one-way device, including a forming mold body 1. The forming mold body 1 has a mold mounting groove 101 inside and a pusher component mounting groove 102 inside. The pusher component mounting groove 102 is connected to the mold mounting groove 101. The outer surface of the forming mold body 1 has symmetrical snap-fit ​​component mounting grooves 103, which are connected to the mold mounting groove 101. The mold body 2 is installed inside the mold mounting groove 101, and the pusher component mounting groove 102 has a pusher component 4 installed inside. Both snap-fit ​​component mounting grooves 103 have snap-fit ​​component mounting grooves 103 installed inside.

[0026] The outer surface of the mold body 2 is symmetrically provided with positioning grooves 201, and the two positioning grooves 201 are connected to the snap-fit ​​component mounting groove 103.

[0027] The snap-fit ​​assembly 3 includes a first spring 301, which is fixedly installed on the inner wall of the snap-fit ​​assembly mounting groove 103, and a mounting plate 302 is fixedly installed on one end of the first spring 301.

[0028] A positioning rod 303 is fixedly installed on one side of the mounting plate 302, and the positioning rod 303 is engaged with the positioning groove 201. A pull rod 304 is fixedly installed on the other side of the mounting plate 302.

[0029] When the forming groove inside the mold body 2 is damaged after long-term use, the mounting plate 302 is pulled by the pull rod 304, compressing the first spring 301 and causing the positioning rod 303 to disengage from the positioning groove 201. Without positioning constraints, the mold body 2 can be easily removed from the mold mounting groove 101 for replacement. The mounting end of the mold body 2 is arc-shaped, and one end of the positioning rod 303 is also arc-shaped. When installing a new mold body 2, the new mold body 2 is inserted into the mold mounting groove 101. The arc surface of the mold body 2 abuts against the arc surface of the positioning rod 303, causing the positioning rod 303 to be compressed and contracted. When the mold body 2 is installed into the positioning groove 201 and docks with the positioning rod 303, the first spring 301 rebounds to complete the automatic locking. Installation and disassembly are convenient and quick, avoiding the need to replace the entire mold body when the forming groove is damaged, thus reducing the cost of use.

[0030] The pusher assembly 4 includes a receiving shell 401, which is fixedly installed inside the pusher assembly mounting groove 102. A second spring 402 is fixedly installed at the bottom of the receiving shell 401. A sliding plate 404 is fixedly installed at one end of the second spring 402. The sliding plate 404 is slidably connected to the inner wall of the receiving shell 401.

[0031] A push rod 403 is fixedly installed on the lower surface of the sliding plate 404. The push rod 403 extends to the outer surface of the forming mold body 1 and is slidably connected to the inner wall of the forming mold body 1. A top rod 405 is fixedly installed on the upper surface of the sliding plate 404. The top rod 405 extends to the interior of the mold body 2 and is slidably connected to the inner walls of the forming mold body 1 and the mold body 2.

[0032] Cold heading is performed under external pressure. During the extrusion molding process, the material squeezes the ejector rod 405, causing the ejector rod 405 to drive the sliding plate 404 to slide inside the housing 401. While the sliding plate 404 is sliding, it squeezes the second spring 402. The second spring 402 provides a rebound force to the sliding plate 404. At the same time, the push rod 403 slides outward through the movement of the sliding plate 404. After molding is completed, the sliding plate 404 is rebounded by the rebound force of the second spring 402, thereby causing the sliding plate 404 to drive the ejector rod 405 to lift the molded material, thus completing automatic demolding. If the second spring 402 does not automatically eject the material, the push rod 403 can be manually pushed to apply a greater force to push the material out.

[0033] In use, the material is first placed inside the mold body 2 and cold-formed under external pressure. During the extrusion molding process, the material presses against the ejector pin 405, causing the ejector pin 405 to drive the sliding plate 404 to slide inside the receiving shell 401. Simultaneously, the sliding plate 404 presses against the second spring 402, which provides a rebound force to the sliding plate 404. At the same time, the push rod 403 extends outwards through the movement of the sliding plate 404. After molding, the second spring 402 rebounds the sliding plate 404, causing the sliding plate 404 to drive the ejector pin 405 to lift the molded material, thus completing automatic demolding. If the second spring 402 fails to automatically eject the material, the push rod 403 can be manually pushed to apply greater force to push the material out. When the forming groove inside the mold body 2 is long... When the mold body 2 is damaged during use, the mounting plate 302 is pulled by the pull rod 304, compressing the first spring 301 and causing the positioning rod 303 to disengage from the positioning groove 201. Without positioning constraints, the mold body 2 can be easily removed from the mold mounting groove 101 for replacement. The mounting end of the mold body 2 is arc-shaped, and one end of the positioning rod 303 is also arc-shaped. When installing a new mold body 2, the new mold body 2 is inserted into the mold mounting groove 101. The arc surface of the mold body 2 abuts against the arc surface of the positioning rod 303, causing the positioning rod 303 to be compressed and contracted. When the mold body 2 is installed into the positioning groove 201 and docks with the positioning rod 303, the first spring 301 rebounds to complete the automatic locking. Installation and disassembly are convenient and quick, avoiding the need for complete replacement when the molding groove is damaged, thus reducing the cost of use.
