Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a rapid cooling stamping die for automotive parts. Background Technology

[0002] Stamping dies are specialized processing equipment used to process raw materials (such as metals or non-metals) into desired parts or semi-finished products. They use pressure to cause plastic deformation or fracture of the material within the die, thereby achieving predetermined shapes, dimensions, and precision requirements. In automobile manufacturing, many key components, such as body shells, brackets, and chassis, are typically processed using stamping technology. These components often require precision stamping dies for production. Stamping dies not only improve production efficiency and ensure product consistency and precision but also reduce costs, making them particularly suitable for mass production. With continuous technological advancements, the design and manufacturing precision of stamping dies are constantly improving, enabling the efficient production of increasingly complex automotive parts through stamping processes.

[0003] In the prior art, the high temperature of the stamped parts may cause thermal fatigue and thermal deformation of the mold material, which in turn affects the service life of the mold and the accuracy of stamping.

[0004] Therefore, it is necessary to provide a new rapid cooling stamping die for automotive parts to solve the above-mentioned technical problems. Utility Model Content

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] Please see Figures 1 to 4 This utility model provides a rapid cooling stamping die for automotive parts, comprising a base assembly 1.

[0026] The base assembly 1 is equipped with a pressure-conducting heat-conducting component 2 inside. A baffle 8 is fixed to the top of the base assembly 1. A lower mold assembly 3 is provided above the pressure-conducting heat-conducting component 2. A fixing plate 4 is fixed to one side of the outer wall of the base assembly 1. A housing 5 is fixed to the upper side of the inner side of the fixing plate 4. A hydraulic push rod 6 is installed at the top of the housing 5. An upper mold assembly 7 is provided at the output end of the hydraulic push rod 6.

[0027] The pressure-bearing heat-conducting component 2 includes a base plate 201, which slides vertically above the base assembly 1. Multiple fixing blocks 202 are fixed at the bottom end of the base plate 201, and a connecting rod 203 is fixed at the bottom end of the fixing block 202. A connecting spring 204 is sleeved on the surface of the connecting rod 203. A limit block 205 is fixed at the bottom end of the connecting rod 203 inside the base assembly 1. A heat-conducting sheet 206 extending into the interior of the base assembly 1 is fixed at the center of the bottom end of the base plate 201.

[0028] It should be noted that the base assembly, as the supporting foundation of the mold, provides a stable support platform, ensuring structural stability throughout the stamping process. The pressure-bearing heat-conducting component 2 and the hydraulic push rod 6 ensure efficient cooling and precise operation of the mold.

[0029] The vertical sliding of the base plate 201 and the elasticity of the fixing block ensure proper pressure and temperature control during the pressing process. The sliding of the connecting rod 203 and the cooperation of the heat-conducting plate 206 effectively guide heat flow to the base, preventing overheating or undercooling from affecting the stamping effect.

[0030] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 The base assembly 1 includes a base body 101, the interior of which is provided with a cavity 102, the top of which is provided with a plurality of grooves 103, and the bottom of which is provided with a circular hole 104 communicating with the cavity 102.

[0031] It should be noted that: cavity 102 and groove 103 provide space for coolant to be contained and flow, while circular hole 104 ensures the flow path of coolant.

[0032] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 The connecting rod 203 and the limiting block 205 form an inverted T-shape. The connecting rod 203 slides vertically on the top of the base body 101. The limiting block 205 is placed inside the cavity 102. The limiting block 205 forms a limiting structure for the connecting rod 203.

[0033] It should be noted that the inverted T-shaped connecting rod and limiting block provide precise guidance and limiting functions, ensuring accurate relative movement between components.

[0034] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 The sliding distance of the connecting rod 203 is the same as the sliding distance of the heat-conducting plate 206, and the heat-conducting plate 206 is curved.

[0035] It should be noted that the curved design effectively increases the contact area with the heat source, thereby improving thermal conductivity. The sliding fit between the heat-conducting plate 206 and the connecting rod 203 ensures uniform heat distribution and rapid heat dissipation, avoiding localized overheating and improving the overall cooling performance of the mold.

[0036] In the embodiments of this utility model, please refer to Figure 3 and Figure 4 The upper mold assembly 7 includes a mounting plate 701, which slides vertically at the bottom of the housing 5.

A stamping block 704 slides laterally at the center of the bottom of the mounting plate 701.

[0037] It should be noted that the design of the upper die assembly ensures precise positioning and stable movement of the upper die, and the hydraulic push rod 6 provides sufficient pushing force to ensure the smooth progress of the stamping process. The structural design of the guide hole 702 and the stamping block 704 provides precise guiding and positioning functions, effectively avoiding deviations and errors in the movement of the die.

[0038] In the embodiments of this utility model, please refer to Figure 3 and Figure 4 The lower mold assembly 3 includes a lower mold body 301, which slides laterally on the top of the base plate 201. A tapered column 302 is fixed at the top of the lower mold body 301 at the corresponding position of the guide hole 702.

[0039] It should be noted that the design of the tapered column 302 ensures precise docking between the lower and upper dies, guaranteeing efficient cooperation and stability during the stamping process.

[0040] In the embodiments of this utility model, please refer to Figure 3 and Figure 4 The mounting plate 701 and the base plate 201 have riveting grooves 703 on their opposite inner sides. The stamping block 704 is fixed with a riveting block 9 on the side that is separated from the lower mold body 301. The riveting block 9 and the riveting groove 703 form a tenon-and-mortise connection. The surfaces of the riveting block 9 and the inner side of the riveting groove 703 are in close contact.

[0041] It should be noted that the mortise and tenon connection method of the rivet groove and rivet block provides strong connection force, ensuring tight connection and reliability between the components, improving the durability and stability of the mold, and effectively preventing the components from loosening or being damaged during long-term use.
