Description

Technical Field

[0001] This utility model mainly relates to the field of stamping die technology, specifically to a quick-change structure for the core of a radiator stamping die. Background Technology

[0002] In the production of radiators in diverse fields such as electronic equipment, automotive power systems, and industrial refrigeration, there are many types and specifications of radiators due to the significant differences in the requirements for heat dissipation efficiency and space adaptability in different scenarios. The core of the stamping die is an important structure that determines the stamping formation of the radiator. The stamping die needs to be frequently replaced with different specifications of cores to adapt to various radiator models.

[0003] Traditional mold cores are mostly fastened directly with bolts. When changing molds, bolts need to be removed one by one, which is cumbersome and time-consuming, seriously affecting production efficiency. Repeated disassembly and assembly can lead to a decrease in the positioning accuracy of the mold core, which in turn affects the stamping quality of the radiator.

[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0006] 2. Technical Solution: To achieve the above objectives, the technical solution provided by this utility model is as follows: a quick-change structure for the core of a radiator stamping die, comprising an upper template, a lower template, guide pillars, and a hydraulic connection assembly. The upper template is provided with a rotation locking mechanism at its upper end, and a core is embedded in the upper template. A positioning plate is provided on the lower template. The upper template and the lower template are connected by multiple guide pillars, and the hydraulic connection assembly is fixed above the rotation locking mechanism.

[0007] Furthermore, the upper template has a dovetail groove at its lower end, a disassembly groove at its rear end, and an open end at its front end, which is provided with a limiting installation block.

[0008] Furthermore, the limiting installation block is embedded in the front end of the dovetail groove, and both ends are connected to the upper template through positioning pins.

[0009] Furthermore, the two sides of the mold core match the contour of the dovetail groove, the upper end of the mold core is provided with an assembly hole, the assembly hole is provided with a locking groove, and the two sides of the assembly hole are provided with positioning slots.

[0010] Furthermore, the rotary locking mechanism includes a rotary cylinder, the drive end of which is connected to a locking shaft head, which passes through the upper template and matches the assembly hole.

[0011] Furthermore, a fixing frame is provided between the hydraulic connection assembly and the upper template, and the rotary cylinder is fixed to the upper end of the upper template through the fixing frame.

[0012] 3. Beneficial effects: Compared with the prior art, the technical solution provided by this utility model has the following advantages: The dovetail groove sliding installation and the insertion, rotation and locking action of the rotary locking mechanism eliminate the need for traditional bolt disassembly and assembly, greatly shortening the mold change time and improving production efficiency. The dovetail groove, positioning slot and guide column work together to ensure the installation accuracy of the mold core and ensure the stamping quality of the radiator. The rotary cylinder drives the locking shaft head to rotate and lock into the locking groove, ensuring reliable locking without loosening. It is practical and economical.

[0020] See attached document Figure 1-6 A quick-change structure for the core of a radiator stamping die includes an upper template 1, a lower template 2, guide pillars 3 and a hydraulic connection assembly 4. The upper template 1 is provided with a rotation locking mechanism 5 at its upper end. The upper template 1 is embedded with a core 6. The lower template is provided with a positioning plate 7. The upper template 1 and the lower template 2 are connected by multiple guide pillars 3. The hydraulic connection assembly 4 is fixed above the rotation locking mechanism 5.

[0021] The upper template 1 and the lower template 2 are coaxially connected by four guide columns 3. The guide columns 3 are vertically fixed at the four corners of the lower template 2. Guide holes are opened at the four corners of the upper template 1. The guide columns 3 are symmetrically distributed at the four corners of the two templates and are fitted with the guide columns 3 with a clearance to ensure the coaxiality and straightness of the upper template's up and down movement.

[0022] The upper template 1 has a dovetail groove 101 at its lower end. The rear end of the dovetail groove 101 has a disassembly groove 102 to facilitate the insertion of tools to disassemble and assemble the auxiliary mold core. The front end is an open end with a limiting installation block 103. The limiting installation block 103 is detachably connected to the upper template 1 via a positioning pin 104 to limit the sliding range of the mold core 6 within the dovetail groove 101. The contours on both sides of the mold core 6 match the shape of the dovetail groove 101 and can be slidably installed along the dovetail groove.

[0023] The upper end of the mold core 6 is provided with an assembly hole 601, and a locking groove 6011 is provided in the assembly hole 601. Positioning slots 6012 are provided on both sides. The rotation locking mechanism 5 includes a rotary cylinder 501 and a locking shaft head 502. The rotary cylinder 501 is fixed to the upper end of the upper template 1 by a fixing bracket 8. Its driving end is connected to the locking shaft head 502. The locking shaft head 502 penetrates the upper template 1 and is inserted into the assembly hole 601. The rotary cylinder drives the locking shaft head to rotate 90°, so that the locking shaft head 502 is engaged in the locking groove 6011, thereby realizing the circumferential locking of the mold core.

[0024] The hydraulic connection assembly 4 is fixed above the rotary locking mechanism 5 and is used to connect external hydraulic equipment to transmit stamping power; the upper end face of the lower template 2 is fixed with a positioning plate 7, which is used to position the radiator plate before stamping to ensure the stamping dimensional accuracy.

[0025] During mold changing, the rotary cylinder 501 drives the locking shaft head 502 to rotate in the opposite direction and disengage from the locking groove 6011. Then, the positioning pin 104 on the connecting limit mounting block 103 is removed, and the limit mounting block 103 is removed. The mold core 6 is pushed forward through the disassembly groove 102, and the old mold core is pulled out along the dovetail groove 101. The new mold core is slid into the dovetail groove 101, inserted into the locking shaft head 502, and driven to rotate and lock. The limit mounting block 103 is then reinstalled to complete the mold changing process. The whole process is quick and convenient.

[0026] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
