[0002] Insulation molds are a type of mold used for specific applications in the moldmaking industry. Insulation molds can also be a special type of injection mold, primarily used for the production of plastic products that require good insulation properties. This type of injection mold is often made from materials with good insulation properties to ensure that the necessary insulation properties are maintained during the injection molding process and in the use of the final product.

[0003] Traditional insulated injection molds have a simple structure and poor cooling cycle effect. They rely solely on cooling water circulation to cool down the mold, which reduces the cooling efficiency of the mold and makes it difficult to lower the temperature of the mold after long-term operation, causing the mold to be in a high temperature state, thereby affecting the quality of the finished product after injection molding. Utility Model Content

[0004] The purpose of the utility model is to provide an insulating mold with a cooling function, which can cool the mold more effectively by using air cooling in combination with water cooling, so that the mold is not prone to high temperature even when working for a long time.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solutions: an insulating mold with a cooling function, comprising an injection molding mechanism, wherein a cooling mechanism is provided on the surface of the injection molding mechanism;

[0006] The injection molding mechanism includes a base, a support platform is fixed on the top of the base, a first cylinder is fixed on the surface of the support platform, one end of the first cylinder passes through the support platform and is fixed with an upper mold, and a lower mold is fixed on the surface of the base;

[0007] The cooling mechanism includes a fan, which is fixed to the surface of the support platform. The surface of the fan is connected to a connecting pipe, which passes through the support platform. An L-shaped pipe is provided below the connecting pipe. A support plate is fixed to the surface of the upper mold. The L-shaped pipe is fixedly connected to the surface of the support plate. One end of the L-shaped pipe is connected to a rotary joint, and the rotating end of the rotary joint is connected to an air outlet pipe. The surface of the air outlet pipe is connected to multiple nozzles. A driving structure is installed on the surface of the air outlet pipe. A first water-cooling pipe and a second water-cooling pipe are embedded and fixed in the middle of the inner wall of the lower mold, and an air-cooling diverter pipe is embedded and fixed on the lower side of the lower mold.

[0008] As an insulating mold with cooling function preferred in the present invention, a second cylinder is fixed on the top of the upper mold, one end of the second cylinder passes through the upper mold and is fixed with a rack, a gear is fixed on the surface of the air outlet pipe, and the rack is engaged with the gear.

[0009] As a preferred insulating mold with a cooling function of the present invention, the first water-cooling pipe and the second water-cooling pipe are both arranged in a mesh-shaped structure.

[0010] As an insulating mold with cooling function preferred in the present invention, the first water-cooling tube, the second water-cooling tube and the air-cooling shunt tube are all made of copper alloy, and the surfaces of the first water-cooling tube, the second water-cooling tube and the air-cooling shunt tube are all wrapped with a layer of insulating material.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The utility model can achieve a faster cooling effect for the mold by setting the cooling mechanism. After the injection molding is completed, the fan is first turned on to transmit the air flow to the inside of the air outlet pipe through the connecting pipe, the L-shaped pipe and the rotary joint, and then ejected outwards from the nozzle. At the same time, the driving mechanism can also drive the air outlet pipe to rotate back and forth, so that the range of the air flow ejected by the nozzle can be further increased, thereby expanding the cooling range of the upper mold and the lower mold surface. In this way, the upper mold and the lower mold surface are initially cooled by the air flow, and then the external coolant is introduced into the second water cooling pipe so that the coolant can pass through the first water cooling pipe. The cooling pipe is discharged from one end thereof, while the second water-cooling pipe and the first water-cooling pipe can increase the overall length of the pipe and form turbulence in the fluid inside it. In the turbulent state, the water molecules move more violently in the direction perpendicular to the flow, resulting in more mixing and energy exchange, thereby improving the water-cooling heat exchange efficiency. At the same time, one end of the air-cooling diverter pipe can be connected to the external air supply equipment, so that the air flow can further take away the heat inside the mold through the air-cooling diverter pipe, which helps to reduce local overheating. The combination of the two can achieve a more efficient cooling effect, help to improve the dimensional stability of the product, and reduce the defective rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] See also Figures 1-6 , an insulating mold with a cooling function, comprising an injection molding mechanism 1, a cooling mechanism 2 is provided on the surface of the injection molding mechanism 1;

[0023] The injection molding mechanism 1 is used to perform injection molding, and the cooling mechanism 2 enables the mold to achieve a faster cooling effect.

[0024] The injection molding mechanism 1 includes a base 101, a support platform 102 is fixed on the top of the base 101, a first cylinder 105 is fixed on the surface of the support platform 102, one end of the first cylinder 105 passes through the support platform 102 and is fixed with an upper mold 104, and a lower mold 103 is fixed on the surface of the base 101;

[0025] When the first cylinder 105 is activated, it drives the upper mold 104 to move downward, so that the upper mold 104 can be closed with the lower mold 103, thereby performing the injection molding work.

[0026] The cooling mechanism 2 includes a fan 201, which is fixed to the surface of the support platform 102. The surface of the fan 201 is connected to a connecting pipe 202, which passes through the support platform 102. An L-shaped pipe 203 is provided below the connecting pipe 202. A support plate 204 is fixed to the surface of the upper mold 104. The L-shaped pipe 203 is fixedly connected to the surface of the support plate 204. One end of the L-shaped pipe 203 is connected to a rotary joint 205. The rotating end of the rotary joint 205 is connected to an air outlet pipe 206. The air outlet pipe The surface of 206 is connected to multiple nozzles 207, and a driving structure is installed on the surface of the air outlet pipe 206. A first water-cooling pipe 208 and a second water-cooling pipe 209 are embedded and fixed in the middle of the inner wall of the lower mold 103. The first water-cooling pipe 208 is connected to the second water-cooling pipe 209. One end of the first water-cooling pipe 208 and the second water-cooling pipe 209 pass through the lower mold 103. An air-cooling shunt pipe 210 is embedded and fixed on the lower side of the lower mold 103. Both ends of the air-cooling shunt pipe 210 pass through the lower mold 103.

[0027] After the injection molding is completed, the fan 201 is first turned on to transmit the air flow through the connecting pipe 202, the L-shaped pipe 203, and the rotary joint 205 to the inside of the air outlet pipe 206 and eject it outward from the nozzle 207. At the same time, the driving mechanism can also drive the air outlet pipe 206 to rotate back and forth, so that the range of the air flow ejected by the nozzle 207 can be further increased, thereby expanding the cooling range of the upper mold 104 and the lower mold 103. In this way, the surface of the upper mold 104 and the lower mold 103 are initially cooled by the air flow, and then the external coolant is introduced into the second water cooling pipe 209 so that the coolant can pass through the first water cooling pipe 208. And discharged from one end thereof, and the second water-cooling pipe 209 and the first water-cooling pipe 208 can increase the overall length of the pipe and make the fluid form turbulence therein. In the turbulent state, the water molecules move more violently in the direction perpendicular to the flow, resulting in more mixing and energy exchange, thereby improving the water-cooling heat exchange efficiency. At the same time, one end of the air-cooling shunt pipe 210 can be connected to the external air supply equipment, so that the air flow can further take away the internal heat of the lower mold 103 through the air-cooling shunt pipe 210, which helps to reduce local overheating. The combination of the two can achieve a more efficient cooling effect, which helps to improve the dimensional stability of the product and reduce the defective rate.

[0028] Furthermore, a second cylinder 212 is fixed to the top of the upper mold 104. One end of the second cylinder 212 passes through the upper mold 104 and is fixed with a rack 213. A gear 214 is fixed to the surface of the air outlet pipe 206. The rack 213 meshes with the gear 214.

[0029] When the second cylinder 212 is started, it can drive the rack 213 to move upward or downward. During this process, the rack 213 will drive the air outlet pipe 206 to move by engaging with the gear 214. By adjusting the second cylinder 212 back and forth, the nozzle 207 can have a larger exhaust cooling range.

[0030] Furthermore, the first water cooling pipe 208 and the second water cooling pipe 209 are both arranged in a reticle-shaped structure;

[0031] The mesh-shaped design causes the fluids to collide and mix at the intersection, thereby further forming turbulence. Under turbulent conditions, the molecules in the fluid are more fully mixed, increasing the heat transfer rate per unit area and thus improving the cooling effect.

[0032] Furthermore, the first water-cooling pipe 208, the second water-cooling pipe 209 and the air-cooling shunt pipe 210 are all made of copper alloy, and the surfaces of the first water-cooling pipe 208, the second water-cooling pipe 209 and the air-cooling shunt pipe 210 are all wrapped with a layer of insulating material;

[0033] Copper alloy has high thermal conductivity. As a cooling pipe, it can quickly absorb the heat transferred from the mold and carry it away through coolant and airflow. The wrapped insulating material can effectively prevent current from leaking into the mold through the first water-cooling pipe 208, the second water-cooling pipe 209 or the air-cooling shunt pipe 210, ensuring the safety of operators and the normal operation of the equipment, and avoiding short circuits.

[0034] Furthermore, one end of the second water-cooling pipe 209 is connected to a reducing pipe 211;

[0035] When the coolant enters the second water-cooling tube 209 through the reducing tube 211, the fluid velocity is forced to increase due to the sudden decrease in the cross-sectional area of ​​the channel, and the high flow rate easily forms turbulence near the reducing point. This structure is conducive to increasing the local flow velocity, thereby improving the convective heat transfer efficiency and enhancing the cooling effect.

[0036] Furthermore, the bottom of the connecting pipe 202 is connected to a bellows 215 , and the bottom of the bellows 215 is connected to the top of the L-shaped pipe 203 ;

[0037] When the upper mold 104 moves up and down, the bellows 215 can be expanded and contracted, thereby ensuring that the air flow can be normally transmitted inside the bellows 215.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
