Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a high-efficiency heat dissipation mold. Background Technology

[0002] When a mold is in operation, there will be a high temperature inside. The internal workpiece needs to be formed after it cools down. Molds that can significantly improve heat dissipation efficiency are usually achieved through optimized design, the use of high-efficiency heat dissipation materials, or innovative heat dissipation structures.

[0003] Patent CN221754699U discloses a high-efficiency heat-dissipating aluminum profile mold, including a support platform, a lower mold mounted on the support platform, and an upper mold mounted on the lower mold. A cooling cavity is formed inside the lower mold, and multiple heat-conducting fins are fixedly mounted inside the cooling cavity. A first conduit and a second conduit are fixedly mounted on the outer wall of the lower mold. A U-shaped heat dissipation pipe is mounted at the end of the first conduit, and a third conduit is mounted at the bottom of the U-shaped heat dissipation pipe. A circulation pump is installed between the third conduit and the second conduit. Multiple heat dissipation fins are fixedly mounted on the outer wall of the U-shaped heat dissipation pipe. Cold water is introduced into the cooling cavity through the first conduit to dissipate heat and cool the lower mold. After the U-shaped heat dissipation pipe is full, water injection is stopped, and the circulation pump is started, allowing water in the cooling cavity to be introduced into the U-shaped heat dissipation pipe through the first conduit. The water in the U-shaped heat dissipation pipe is cooled by the multiple heat dissipation fins, and then the lower mold is cooled, preventing the cold water in the lower mold from affecting the heat dissipation effect due to high temperature.

[0004] The above-mentioned device has certain shortcomings when in use: the device dissipates heat from the lower mold, but the entire mold cavity is filled with high temperature when the mold is working. When the lower mold continues to dissipate heat, the temperature inside the upper mold cavity will continue to dissipate downwards, which will affect the heat dissipation effect of the entire mold.

[0005] Therefore, this utility model provides a high-efficiency heat dissipation mold to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a high-efficiency heat dissipation mold, which solves the aforementioned problems.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a high-efficiency heat dissipation mold, including a base, a lower mold installed on the top wall of the base, a mold closing assembly installed on the top wall of the base, an upper mold installed on the bottom wall of the mold closing assembly, heat dissipation assemblies installed inside both the upper and lower molds, and auxiliary components installed on the outer wall of the heat dissipation assemblies.

[0008] The heat dissipation assembly includes a circulating cooling pipe. A heat dissipation cavity is opened inside the lower mold. The front and rear parts of the circulating cooling pipe are fixedly connected to the inner wall of the heat dissipation cavity through mounting bases. A water outlet pipe is connected to the rear part of the circulating cooling pipe, and a connecting pipe is connected to the front part of the circulating cooling pipe. A circulating pump is fixedly installed on the right side wall of the upper mold. A water inlet pipe is connected to the inlet of the circulating pump, and a discharge pipe is connected to the outlet of the circulating pump. A cooling box is fixedly installed on the right side wall of the lower mold. Heat dissipation fins are evenly installed inside the cooling box, and a water supply pipe is connected to the front end of the cooling box.

[0009] Through the above technical solution, the heat dissipation components are designed so that cooling water circulates inside the cooling pipe, which can absorb and remove the temperature inside the mold, thus providing the mold with efficient heat dissipation.

[0010] Furthermore, the right end of the outlet pipe passes through the lower mold via a leak-proof rubber sleeve and is connected to the top of the inlet pipe via a connecting flange. The front end of the discharge pipe is connected to the cooling box, and the right side wall of the cooling box is fixedly connected to the auxiliary components.

[0011] With the above technical solution, after the cooling water enters the inlet pipe through the outlet pipe, it then enters the interior of the cooling tank through the outlet pipe.

[0012] Furthermore, a sealing cover is installed on the top wall of the cooling box, and the tops of several heat sinks all pass through the sealing cover and extend to the outside. The right end of the connecting pipe passes through the lower mold through a leak-proof rubber sleeve and is connected to the front end of the water supply pipe through a connecting flange.

[0013] Through the above technical solution, the sealing cover has a sealing effect on the cooling box, and the heat sink mainly conducts the temperature of the cooling water outward.

[0014] Furthermore, the auxiliary components include two U-shaped seats arranged symmetrically front to back. Support seats are fixedly installed on the inner walls of the two U-shaped seats, circular frames are fixedly installed on the top of the two support seats, and mounting brackets are fixedly installed on the inner walls of the two circular frames.

[0015] The U-shaped base, as described above, is primarily used for mounting support bases, circular frames, and mounting brackets.

[0016] Furthermore, drive motors are fixedly mounted on the outer walls of both mounting brackets, and cooling fans are fixedly mounted on the power shafts of the two drive motors through bearings passing through the mounting brackets.

[0017] The above technical solution enables the drive motor to drive the cooling fan to emit cold air, which can help cool the top of the heat sink.

[0018] Furthermore, the mold closing assembly includes a top seat, and positioning rods are fixedly installed at the four corners of the bottom end of the top seat, with the bottom ends of several positioning rods being fixedly connected to the top wall of the base.

[0019] The above technical solution mainly uses the positioning rod to limit the movement path of the sliding seat and the upper mold, thereby improving the accuracy of mold closing.

[0020] Furthermore, an electric actuator is fixedly installed on the top wall of the top seat. The movable end of the electric actuator slides through the fixedly installed sliding seat on the top seat. The four corners of the outer wall of the sliding seat are slidably connected to the outer wall of the corresponding positioning rod, and the bottom wall of the sliding seat is fixedly connected to the top wall of the upper mold.

[0021] The above technical solution uses an electric actuator to push the sliding seat along the outer wall of the positioning rod, thereby driving the upper mold to gradually move downwards and close with the lower mold.

[0022] Beneficial effects

[0023] This invention provides a high-efficiency heat dissipation mold. Compared with the prior art, it has the following advantages:

[0024] (1) The high-efficiency heat dissipation mold, through the cooperation of heat dissipation components and auxiliary components, can simultaneously perform high-efficiency heat dissipation treatment on the upper and lower molds in the mold, and at the same time provide auxiliary heat dissipation for the heat sink, so that the conducted temperature drops faster and the temperature of the cooling water drops synchronously, thereby improving the heat dissipation rate of the entire mold.

[0025] (2) The high-efficiency heat dissipation mold, through the setting of the mold closing component, can quickly match and dock when processing the workpiece, preventing positional deviation during mold closing and improving the accuracy of mold closing. Attached Figure Description

[0034] 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.

[0035] Example 1:

[0036] Please see Figures 1-7 A high-efficiency heat dissipation mold includes a base 1, a lower mold 4 installed on the top wall of the base 1, a mold closing assembly 2 installed on the top wall of the base 1, an upper mold 3 installed on the bottom wall of the mold closing assembly 2, heat dissipation assemblies 5 installed inside both the upper mold 3 and the lower mold 4, and auxiliary components 6 installed on the outer wall of the heat dissipation assembly 5.

[0037] The heat dissipation assembly 5 includes a circulating cooling pipe 52. A heat dissipation cavity 51 is formed inside the lower mold 4. The front and rear ends of the circulating cooling pipe 52 are fixedly connected to the inner wall of the heat dissipation cavity 51 via mounting bases 53. A water outlet pipe 55 is connected to the rear end of the circulating cooling pipe 52, and a connecting pipe 54 is connected to the front end. A circulating pump 57 is fixedly installed on the right side wall of the upper mold 3. A water inlet pipe 58 is connected to the inlet of the circulating pump 57, and a discharge pipe 59 is connected to the outlet of the circulating pump 57. A cooling box 510 is fixedly installed on the right side wall of the lower mold 4. The cooling box 510 contains evenly distributed cooling components. The heat sink 511 and the cooling box 510 are connected to the front end of the water supply pipe 56. The right end of the water outlet pipe 55 passes through the lower mold 4 through the anti-leakage rubber sleeve and is connected to the top of the water inlet pipe 58 through the connecting flange. The front end of the discharge pipe 59 is connected to the cooling box 510. The right side wall of the cooling box 510 is fixedly connected to the auxiliary component 6. The top wall of the cooling box 510 is equipped with a sealing cover 512. The top ends of several heat sinks 511 pass through the sealing cover 512 and extend to the outside. The right end of the connecting pipe 54 passes through the lower mold 4 through the anti-leakage rubber sleeve and is connected to the front end of the water supply pipe 56 through the connecting flange.

[0038] In this embodiment of the utility model, the purpose of this arrangement is that, when the heat dissipation component 5 is in operation, the cooling water circulates in the inner wall of the circulating cooling pipe 52, absorbing and driving the temperature inside the upper mold 3 and the lower mold 4, thereby achieving efficient heat dissipation of the mold. The heat is absorbed by the heat dissipation fins 511 in the cooling box 510 and dissipated outward through the top, which can quickly cool the cooling water and return it to the inside of the circulating cooling pipe 52.

[0039] Example 2:

[0040] Please see Figures 1-7 This embodiment provides a technical solution based on embodiment one: the auxiliary component 6 includes two U-shaped seats 61 arranged symmetrically front and back. Support seats 62 are fixedly installed on the inner walls of the two U-shaped seats 61. Circular frames 63 are fixedly installed on the tops of the two support seats 62. Mounting frames 64 are fixedly installed on the inner walls of the two circular frames 63. Drive motors 66 are fixedly installed on the outer walls of the two mounting frames 64. Cooling fans 65 are fixedly installed through bearings through the mounting frames 64. The mold closing component 2 includes a top seat 21. Positioning rods 23 are fixedly installed at the four corners of the bottom of the top seat 21. The bottom ends of several positioning rods 23 are fixedly connected to the top wall of the base 1. Electric push rods 22 are fixedly installed on the top wall of the top seat 21. The movable end of the electric push rod 22 slides through the top seat 21 and is fixedly installed on a sliding seat 24. The four corners of the outer wall of the sliding seat 24 are slidably connected to the outer walls of the corresponding positioning rods 23. The bottom wall of the sliding seat 24 is fixedly connected to the top wall of the upper mold 3.

[0041] In this embodiment of the utility model, the purpose of this arrangement is that the auxiliary component 6 can dissipate heat from the outer wall of the heat sink 511, so that the heat of the heat sink 511 can be quickly dissipated, which has an auxiliary cooling effect on the cooling water. At the same time, the mold closing component 2 can improve the mold closing accuracy of the upper mold 3 and the lower mold 4 during operation, and prevent the problem of positional displacement during mold closing.

[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0043] The working principle of this device is as follows: First, the electric push rod 22, the circulating pump 57 and the drive motor 66 are electrically connected through an external power supply and controller. When the mold is closed, the mold closing assembly 2 works together. The electric push rod 22 pushes the sliding seat 24 to slide down along the outer wall of the positioning rod 23, thereby driving the upper mold 3 to close with the lower mold 4 to complete the matching and docking.

[0044] When it is necessary to cool the upper mold 3 and the lower mold 4, the drive motor 66 is started first to drive the cooling fan 65 to rotate in the mounting bracket 64 and the circular bracket 63, and the cold air blown out by the cooling fan 65 dissipates heat on the top outer wall of the heat sink 511.

[0045] Next, the circulation pump 57 is started to draw out the cooling water inside the circulating cooling pipe 52 through the inlet pipe 58 and the outlet pipe 55. When the cooling water flows inside the circulating cooling pipe 52, it will absorb the heat in the heat dissipation cavity 51 and the lower mold 4. After passing through the inlet pipe 58 and the outlet pipe 59, it enters the cooling box 510. After the heat dissipation of the cooling water that has absorbed heat through the heat dissipation fins 511, the heat will be transferred to the top of the heat dissipation fins 511. At the same time, the cold air blown out by the cooling fan 65 will continue to cool the top of the heat dissipation fins 511, thereby cooling the cooling water inside the cooling box 510.

[0046] The cooling water then returns to the circulating cooling pipe 52 through the water supply pipe 56 to continue absorbing heat, repeating the above process to efficiently dissipate heat from the upper mold 3 and the lower mold 4.
