Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a combined mold cavity for die casting mold. Background Technology

[0002] In the field of die casting molds, when manufacturing workpieces with multiple heat dissipation fins, it is usually necessary to form a complex and dense fin structure in the mold cavity. However, the mold cavity of traditional die casting molds is mostly an integral design with a fixed internal structure, which makes it impossible to flexibly adjust the shape, spacing or height of the fins.

[0003] In practical applications, different users have different requirements for the size, distribution and shape of heat dissipation fins. For example, some applications require high-density, thin-walled fins to improve heat dissipation efficiency, while other applications may require thicker fins to enhance structural strength. Because the mold cavity is fixed, traditional molds must be redesigned and manufactured to produce heat dissipation fin workpieces of different specifications, resulting in high production costs, long production cycles and difficulty in responding quickly to market demands. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a combined mold cavity for die casting molds, which solves the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a combined mold cavity for die casting, comprising a moving mold and a mold cavity disposed on the top of the moving mold, wherein multiple equally spaced retaining plates are detachably arranged on the two opposite side walls of the mold cavity, and a receiving cavity is provided between adjacent retaining plates, wherein a receiving groove is provided on the retaining plate, and a first plate and a second plate are respectively inserted into the receiving cavity and the receiving groove; when replacing the first plate and / or the second plate, the first plate and / or the second plate can be removed from the corresponding receiving cavity and / or receiving groove by pulling out the retaining plate.

[0006] Furthermore, the first and second plates are trapezoidal, forming an inverted trapezoidal liquid cavity between adjacent first and second plates.

[0007] Furthermore, both the first and second plates have ribs on their side walls that can abut against the lower end of the card plate.

[0008] Furthermore, the end wall of the card plate facing the second plate is inverted trapezoidal, and the lower end wall of the card plate is arc-shaped.

[0009] Furthermore, the bottom of the mold cavity is provided with at least two oppositely arranged protrusions, and the bottom of the first plate and the second plate are provided with slots that adapt to the protrusions.

[0010] Furthermore, a movable ejector pin is provided at the bottom of the mold cavity, and guide grooves matching the movement trajectory of the ejector pin are provided on both sides of the first and second plates, so that the workpiece cast between the first and second plates can be ejected by the ejector pin.

[0011] Furthermore, the thimble is a rectangular needle.

[0012] Furthermore, the inner walls of the mold cavity are provided with insertion slots to accommodate the card plate.

[0013] Furthermore, a baffle is attached to the top of the insertion slot, and the baffle can be bolted to the moving mold and clamped to restrict its displacement.

[0014] Compared with the prior art, this utility model has significant advantages and beneficial effects. Specifically, as can be seen from the above technical solution, by adopting a detachable clamping plate design, operators can flexibly replace the first plate and / or the second plate according to the manufacturing requirements of different workpieces to adjust the internal structure of the mold cavity, thereby quickly adapting to the production of products of different specifications. For example, when it is necessary to manufacture workpieces with different heat dissipation fin spacing or height, only the second plate of the corresponding shape needs to be replaced, without replacing the entire mold cavity, which greatly reduces the mold modification cost. In addition, this structure allows for local adjustments based on the existing mold cavity, optimizes the use of the mold, and improves production flexibility.

[0015] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0021] Explanation of reference numerals in the attached diagram: Moving model 10; Mold cavity 20, insertion groove 20a, protrusion 201, retaining plate 21, receiving cavity 22, receiving groove 23, first plate 24, second plate 25, rib 251, liquid cavity 26, retaining groove 27, ejector pin 28, guide groove 29; Baffle 30. Detailed Implementation

[0022] Please refer to Figure 1-5 As shown, it illustrates the specific structure of a preferred first embodiment of the present invention, which is a combined mold cavity for die casting, including a movable mold 10 and a mold cavity 20 disposed on the top of the movable mold 10. Multiple equidistantly arranged retaining plates 21 are detachably disposed on two opposite side walls of the mold cavity 20. There is a receiving cavity 22 between two adjacent retaining plates 21. A receiving groove 23 is provided on the retaining plate 21. A first plate 24 and a second plate 25 are respectively inserted into the receiving cavity 22 and the receiving groove 23. When replacing the first plate 24 and / or the second plate 25, the first plate 24 and / or the second plate 25 can be removed from the corresponding receiving cavity 22 and / or receiving groove 23 by pulling out the retaining plate 21. By adopting a detachable clamping plate 21 design, operators can flexibly replace the first plate 24 and / or the second plate 25 according to the manufacturing requirements of different workpieces to adjust the internal structure of the mold cavity 20, thereby quickly adapting to the production of products of different specifications. For example, when it is necessary to manufacture workpieces with different heat dissipation fin spacing or height, only the second plate 25 of the corresponding shape needs to be replaced, without replacing the entire mold cavity 20, which greatly reduces the cost of mold modification. In addition, this structure allows for local adjustments based on the existing mold cavity 20, optimizes the use of the mold, and improves production flexibility.

[0023] It should be noted that when manufacturing workpieces with reinforcing ribs or inverted trapezoidal heat dissipation fins, only the second plate 25 with the corresponding contour needs to be replaced, without remachining the entire mold. This design not only reduces mold manufacturing costs but also shortens product development cycles, making it particularly suitable for small-batch, multi-variety customized production needs.

[0024] In addition, the plug-in structure of the card plate 21 facilitates quick assembly and disassembly, making mold maintenance and replacement more convenient. When a certain plate is worn or needs adjustment, the operator can replace the damaged part individually without scrapping the entire mold cavity 20, further reducing the cost of use.

[0025] For example, the first plate 24 and the second plate 25 are trapezoidal, forming an inverted trapezoidal liquid cavity 26 between adjacent first plates 24 and second plates 25. The inverted trapezoidal liquid cavity 26 is adapted to the shape of the heat sink fins to be manufactured.

[0026] For example, both the first plate 24 and the second plate 25 have ribs 251 on their side walls that can abut against the lower end of the clamping plate 21. By abutting against the clamping plate 21, the upward movement of the first plate 24 and the second plate 25 can be effectively restricted, so as to prevent the first plate 24 and the second plate 25 from moving upward when the workpiece is ejected, thus affecting the demolding effect of the workpiece.

[0027] The end wall of the card plate 21 facing the second plate 25 is inverted trapezoidal, and the lower end wall of the card plate 21 is arc-shaped.

[0028] For example, the bottom of the mold cavity 20 is provided with at least two opposing protrusions 201, and the bottom of the first plate 24 and the second plate 25 are provided with slots 27 that fit the protrusions 201. By precisely embedding the protrusions 201 into the corresponding slots 27, a mechanical interlocking connection is formed. This cooperation method can effectively restrict the horizontal displacement freedom of the first plate 24 and the second plate 25, while preventing the plates from accidentally detaching in the vertical direction.

[0029] The bottom of the mold cavity 20 is provided with a movable ejector pin 28, and the side walls of the first plate 24 and the second plate 25 are provided with guide grooves 29 that match the movement trajectory of the ejector pin 28, so that the workpiece cast between the first plate 24 and the second plate 25 can be ejected by the ejector pin 28.

[0030] The ejector pin 28 is a rectangular pin. The rectangular shape of the ejector pin 28 can reduce the damage to the contact surface between the workpiece and the ejector pin 28 when ejecting the workpiece.

[0031] The inner walls of the mold cavity 20 are provided with insertion slots 20a for accommodating the card plate 21.

[0032] A baffle 30 is attached to the top of the insertion slot 20a, and the baffle 30 can be installed on the moving mold 10 by bolts, and the clamping plate 21 is pressed to restrict its displacement.

[0033] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
