Description

Technical Field

[0001] This utility model relates to the field of processing mold technology, and in particular to a metal alloy processing mold. Background Technology

[0002] Metal alloy processing molds are special tools used to shape metal alloy materials. By applying pressure, temperature or other physical effects, the metal alloy is plastically deformed, solidified or joined according to the specific shape and size of the mold, thereby producing parts or products that meet the design requirements.

[0003] Chinese Patent CN222607967U discloses a zinc alloy automotive parts molding die. This zinc alloy automotive parts molding die includes: a movable plate; a limit post fixedly installed above the movable plate; a bottom mold fixedly installed above the movable plate; a support frame fixedly installed below the movable plate; and a connecting block provided below the support frame. Because the connecting frame is made of copper, which has good thermal conductivity, and surrounds the die-casting space between the receiving plate and the bottom mold, coolant can be introduced into the copper pipe inside the connecting frame during the die-casting process. The coolant carries away the heat absorbed by the connecting frame, creating a temperature difference at the contact surface between the receiving plate and the casting. This allows the heat from the casting to be quickly conducted to the receiving plate, and finally carried away from the mold by the coolant inside the copper pipe. This method can shorten the cooling and forming time of the casting, thereby improving production efficiency.

[0004] However, the above-mentioned technical solution still has the following shortcomings in practical use. Although the square copper tube design used in the above solution is relatively regular in terms of structural layout, it has obvious defects from the perspective of heat conduction. At the corner of the square copper tube, the heat transfer path changes drastically, resulting in uneven temperature gradient distribution. Heat is easily accumulated on the inside of the copper tube corner, forming a local high-temperature area. This causes different temperature drop rates in different parts. In the zinc alloy die casting process, this uneven temperature can generate thermal stress inside the casting, leading to defects such as deformation and cracking. To address these issues, we propose a metal alloy processing mold. Utility Model Content

[0005] The purpose of this invention is to provide a metal alloy processing mold to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a metal alloy processing mold, comprising a lower mold base, an upper mold base disposed on the upper end of the lower mold base, and a cavity formed inside the lower mold base. An installation groove is provided outside the cavity, and a multi-channel annular heat dissipation sleeve is placed within the installation groove. Multiple sets of annular heat-conducting copper tubes are arranged at equal intervals within the multi-channel annular heat dissipation sleeve. A coolant inlet port is provided on the left side of the front end of each set of annular heat-conducting copper tubes, and a coolant outlet port is provided on the right side of the front end of each set of annular heat-conducting copper tubes. A heat insulation plate is installed between the coolant inlet port and the coolant outlet port. A quick-positioning assembly is provided at the front end of the lower mold base.

[0007] As an improved technical solution, the quick positioning component includes positioning sleeves fixed on both sides of the front end of the multi-channel annular heat sink. Guide sleeves are installed on both sides of the front end of the multi-channel annular heat sink on the lower mold base. Movable plates are provided inside both sets of guide sleeves. Positioning pins are fixed at opposite ends of the two sets of movable plates. Paddles are fixed at the front ends of the two sets of movable plates. Return springs are provided at opposite ends of the two sets of movable plates. The opposite ends of the two sets of positioning pins are inserted into the positioning sleeves on both sides of the multi-channel annular heat sink.

[0008] As an improved technical solution, a thermally conductive silicone layer is filled between the outer wall of the multi-channel annular heat dissipation sleeve and the inner wall of the mounting groove.

[0009] As an improved technical solution, the diameter of the annular heat-conducting copper tube gradually increases from the coolant inlet port to the coolant outlet port.

[0010] As an improved technical solution, the heat insulation board is made of multi-layer ceramic fiber composite material, and a temperature sensor is embedded in it.

[0011] As an improved technical solution, the two ends of the reset spring are respectively connected to the outer wall of the movable plate and the inner wall of the guide sleeve, and the movable plate is elastically connected to the inner wall of the guide sleeve through the reset spring.

[0012] As an improved technical solution, the outer wall of the movable plate is fitted with the inner wall of the guide sleeve, and the movable plate and the guide sleeve are slidably connected.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are:

[0014] I. This utility model installs multiple sets of annular heat-conducting copper pipes inside a multi-channel annular heat dissipation sleeve, allowing the annular heat-conducting copper pipes to be evenly distributed within the sleeve. Coolant flows into the annular heat-conducting copper pipes from the coolant inlet port and flows along the annular path, effectively preventing heat accumulation at bends and achieving uniform heat dissipation. This effectively reduces the risk of deformation or cracking caused by thermal stress in the casting. Furthermore, by installing a heat insulation plate between the coolant inlet and outlet ports, the heat insulation plate can block thermal interference between the coolant inlet and outlet ports, thereby ensuring cooling efficiency.

[0015] II. This utility model features two sets of laterally movable positioning pins installed at the front end of the lower mold base. These pins allow for quick release of the multi-channel annular heat sink, facilitating its removal from the mounting groove. This allows for thorough cleaning of the annular heat-conducting copper tubes within the heat sink, ensuring effective heat dissipation. Alternatively, the two sets of positioning pins can be inserted into the positioning sleeves on both sides of the annular heat-conducting copper tubes, enabling quick and easy fixation of the multi-channel annular heat sink's position. This simplifies assembly and prevents misalignment of the multi-channel annular heat sink. Attached Figure Description

Detailed Implementation

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] This utility model provides a technical solution: such as Figures 1 to 4As shown, in this embodiment, a metal alloy processing mold includes a lower mold base 1, an upper mold base 2 disposed on the upper end of the lower mold base 1, and a cavity 3 opened inside the lower mold base 1. An installation groove 4 is provided outside the cavity 3. A multi-channel annular heat dissipation sleeve 5 is placed in the installation groove 4. Multiple sets of annular heat-conducting copper pipes 6 are arranged at equal intervals inside the multi-channel annular heat dissipation sleeve 5. A coolant inlet port 7 is provided on the left side of the front end of the multiple sets of annular heat-conducting copper pipes 6, and a coolant outlet port 8 is provided on the right side of the front end of the multiple sets of annular heat-conducting copper pipes 6. A heat insulation plate 9 is installed between the coolant inlet port 7 and the coolant outlet port 8. A quick positioning component is provided at the front end of the lower mold base 1.

[0023] By installing multiple sets of annular heat-conducting copper pipes 6 inside the multi-channel annular heat dissipation sleeve 5, the annular heat-conducting copper pipes 6 inside the multi-channel annular heat dissipation sleeve 5 are evenly distributed, and the coolant flows into the annular heat-conducting copper pipes 6 from the coolant inlet port 7 and flows along the annular path, effectively avoiding heat accumulation at the corners, achieving uniform heat dissipation, and effectively reducing the risk of deformation or cracking caused by thermal stress in the casting. Furthermore, by installing a heat insulation plate 9 between the coolant inlet port 7 and the coolant outlet port 8, the heat insulation plate 9 can block thermal interference between the coolant inlet port 7 and the coolant outlet port 8, thereby ensuring cooling efficiency.

[0024] In other embodiments, the quick positioning component includes positioning sleeves 10 fixed on both sides of the front end of the multi-channel annular heat sink 5. Guide sleeves 11 are installed on both sides of the front end of the multi-channel annular heat sink 5 on the lower mold base 1. Movable plates 12 are provided inside both sets of guide sleeves 11. Positioning pins 13 are fixed at opposite ends of the two sets of movable plates 12. Paddles 14 are fixed at the front ends of the two sets of movable plates 12. Reset springs 15 are provided at opposite ends of the two sets of movable plates 12. The opposite ends of the two sets of positioning pins 13 are inserted into the positioning sleeves 10 on both sides of the multi-channel annular heat sink 5.

[0025] Two sets of laterally movable positioning pins 13 are installed at the front end of the lower mold base 1. Two sets of paddles 14 can be moved to drive two sets of movable plates 12 to move in opposite directions. During the movement, the two sets of movable plates 12 squeeze the return spring 15 in the guide sleeve 11. When the two sets of positioning pins 13 are completely removed from the positioning sleeves 10 on both sides of the multi-channel annular heat sink 5, the two sets of positioning pins 13 can quickly release the restriction on the multi-channel annular heat sink 5, so that the multi-channel annular heat sink 5 can be pulled out from the mounting groove 4. The annular heat-conducting copper tube 6 inside the multi-channel annular heat sink 5 can be thoroughly cleaned, ensuring the heat dissipation effect of the annular heat-conducting copper tube 6. Alternatively, the two sets of positioning pins 13 can be inserted into the positioning sleeves 10 on both sides of the annular heat-conducting copper tube 6 to quickly fix the position of the multi-channel annular heat sink 5, simplify the assembly steps, and avoid misalignment of the multi-channel annular heat sink 5.

[0026] In other embodiments, a thermally conductive silicone layer is filled between the outer wall of the multi-channel annular heat sink 5 and the inner wall of the mounting groove 4.

[0027] This design allows the thermally conductive silicone layer to fill the gap between the multi-channel annular heat sink 5 and the mounting groove 4, enhancing the thermal conductivity of the contact surface, thereby further optimizing the heat dissipation path, reducing thermal resistance, and improving the overall heat dissipation performance.

[0028] In other embodiments, the diameter of the annular heat-conducting copper tube 6 gradually increases from the coolant inlet port 7 to the coolant outlet port 8.

[0029] By adapting the pipe diameter gradient design to the changes in coolant flow rate, pressure balance is ensured during the flow process, avoiding localized insufficient cooling due to uneven flow rate, and improving the heat dissipation stability of the annular heat-conducting copper pipe 6.

[0030] In other embodiments, the heat insulation panel 9 is made of multilayer ceramic fiber composite material, which has an embedded temperature sensor.

[0031] Through this design, the ceramic fiber composite material is resistant to high temperatures and has strong thermal insulation properties. The temperature sensor monitors the mold temperature in real time, accurately controls the temperature, prevents heat dissipation, and extends the service life of the mold.

[0032] In other embodiments, the two ends of the return spring 15 are respectively connected to the outer wall of the movable plate 12 and the inner wall of the guide sleeve 11, and the movable plate 12 is elastically connected to the inner wall of the guide sleeve 11 through the return spring 15;

[0033] This design allows the return spring 15 to continuously apply a spring force toward the multi-channel annular heat dissipation sleeve 5 to the movable plate 12, thereby enabling the movable plate 12 to drive the positioning pin 13 to quickly insert into the positioning sleeves 10 on both sides of the annular heat-conducting copper pipe 6.

[0034] In other embodiments, the outer wall of the movable plate 12 is in contact with the inner wall of the guide sleeve 11, and the movable plate 12 and the guide sleeve 11 are slidably connected.

[0035] With this design, when the movable plate 12 moves laterally along the inside of the guide sleeve 11, it can prevent the movable plate 12 from shaking significantly during the movement, thereby enabling the movable plate 12 to drive the positioning pin 13 to move laterally in a stable manner.

[0036] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
