Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation, in particular to an injection mold for processing plastic products which is convenient for heat dissipation. Background Art

[0002] The heat dissipation mechanism of the injection mold is a crucial part of the mold design, which directly affects the service life of the mold, product quality and production efficiency. The main function of the heat dissipation mechanism is to quickly dissipate the heat generated by the mold during operation to prevent the mold from deformation or damage due to overheating, while ensuring that the plastic melt is evenly cooled in the mold to obtain high-quality products. Cooling water channels are often used for heat dissipation. Cooling water channels are designed inside the mold to remove heat through circulating cooling water. The design of cooling water channels needs to consider factors such as cooling effect, processing difficulty and mold strength. Reasonable cooling water channel layout can ensure uniform temperature in all parts of the mold and improve cooling efficiency;

[0003] However, in the prior art, when in use, the water channel is a straight line, with water entering at one end and exiting at the other end. The water flows very quickly, and when the water passes through the water channel, it flows out immediately, resulting in that the water temperature cannot be maximized during heat dissipation, resulting in an increase in the power of the water circulation device when in use. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that water flows out immediately when passing through a waterway, resulting in that the temperature of the water cannot be maximized when dissipating heat, resulting in an increase in the power of the water circulation device when in use.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an injection mold for processing plastic products that is easy to dissipate heat, comprising: a cooling mechanism, a heat conducting plate is detachably mounted on one side of the cooling mechanism, a mold is fixedly mounted on one side of the heat conducting plate, the cooling mechanism comprises a base detachably mounted on one side of the heat conducting plate, a device groove is opened at the center of the base, a serpentine tube is fixedly mounted inside the device groove, both ends of the serpentine tube are connected to a reduction device, one end of the reduction device is fixedly connected to a connector, and an insulation pad is fixedly mounted on the inner wall of the device groove.

[0006] As a preferred implementation manner, the depth of the device groove is adapted to the serpentine tube, and one end of the reduction device passes through the device groove.

[0007] As a preferred implementation, the thermal insulation pad is made of polypropylene material.

[0008] As a preferred embodiment, the deceleration device includes a shell connected to one end of the connecting head, a device cylinder is fixedly installed on the inner wall of the shell, a cross bar is fixedly installed inside the device cylinder, a limiting cylinder is fixedly installed on the top of the cross bar, a driving rod is slidably connected to the top of the limiting cylinder, a driving spring is arranged on the outside of the driving rod, a blocking ball is fixedly installed on one end of the driving rod, and a sealing ring is fixedly installed on the outside of the blocking ball.

[0009] As a preferred implementation, one end of the drive spring is fixedly mounted on one end of the limiting cylinder, and the other end of the drive spring is fixedly mounted on one side of the blocking ball.

[0010] As a preferred embodiment, the other end of the shell is connected to one end of the serpentine tube, the diameter of the blocking ball is larger than the diameter of the inner wall of the device tube, and the sealing ring is made of rubber.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] In order to solve the above-mentioned problems, the utility model installs two connecting heads. When in use, water enters the speed reduction device through the connecting heads, and the speed reduction device brings water into the serpentine tube. The serpentine tube is coiled in the device groove, and the insulation pad insulates the inside of the device groove. The serpentine tube increases the stroke of the water inside the device groove. At the same time, the speed reduction device performs secondary speed reduction, thereby solving the problem that water flows out immediately when passing through the waterway in the background technology, resulting in the water temperature not being able to be fully utilized when dissipating heat, resulting in an increase in the power of the water circulation device when in use. When in use, water passes through the device tube, driving the blocking ball to move, driving the spring to stretch and pressurize the water, increasing the pressure and reducing the water flow. When the water passes through the serpentine tube, the pressure is reduced, the water is reduced and the flow rate is reduced. When water is blocked, the driving spring is reset to block the blocking ball on one side of the device tube, and the sealing ring can be sealed to prevent water from flowing back.

[0023] In this embodiment, after the two connectors 15 are installed, when in use, water enters the speed reducer 14 through the connector 15, and the speed reducer 14 brings water into the serpentine tube 13. The serpentine tube 13 is coiled in the device groove 12, and the insulation pad 16 insulates the inside of the device groove 12. The polypropylene material has the characteristics of moisture-proof, and can insulate and dry the inside of the device groove 12 to a large extent. The serpentine tube 13 increases the stroke of water inside the device groove 12, and the speed reducer 14 performs secondary deceleration at the same time, which solves the problem that water in the background technology flows out immediately when passing through the waterway, resulting in the temperature of the water not being able to be maximized when dissipating heat, resulting in an increase in the power of the water circulation device when in use.

[0024] Example 2

[0025] like Figure 1-3 As shown, the reduction device 14 includes a shell 141 connected to one end of the connector 15, the inner wall of the shell 141 is fixedly installed with a device cylinder 142, the interior of the device cylinder 142 is fixedly installed with a cross bar 143, the top of the cross bar 143 is fixedly installed with a limiting cylinder 144, the top of the limiting cylinder 144 is slidably connected with a driving rod 145, the outside of the driving rod 145 is provided with a driving spring 146, one end of the driving rod 145 is fixedly installed with a blocking ball 147, the outside of the blocking ball 147 is fixedly installed with a sealing ring 148, one end of the driving spring 146 is fixedly installed at one end of the limiting cylinder 144, and the other end of the driving spring 146 is fixedly installed on one side of the blocking ball 147, the other end of the shell 141 is connected to one end of the serpentine tube 13, the diameter of the blocking ball 147 is larger than the diameter of the inner wall of the device cylinder 142, and the sealing ring 148 is made of rubber.

[0026] In this embodiment, when in use, water passes through the device tube 142, driving the blocking ball 147 to move, and the blocking ball 147 drives the driving rod 145 to move inside the limiting tube 144, stretching the driving spring 146, driving the driving rod 145 to move inside the limiting tube 144, and the cross bar 143 limits the limiting tube 144.

The water passes through the device cylinder 142, driving the blocking ball 147 to move, and the blocking ball 147 drives the driving The rod 145 moves inside the limiting cylinder 144, stretching the driving spring 146, driving the driving rod 145 to move inside the limiting cylinder 144, and the cross bar 143 limits the limiting cylinder 144. At the same time, the blocking ball 147 drives the sealing ring 148 to leave one side of the device cylinder 142.
