Description

Technical Field

[0001] This utility model relates to the field of injection molding mold technology, specifically to the cooling water channel of injection molding mold. Background Technology

[0002] In the modern plastics processing industry, injection molding is a widely used manufacturing process for producing a wide variety of plastic products, from everyday consumer goods to precision electronic components. During injection molding, the mold cooling system plays a crucial role in the quality, production efficiency, and production cost of the plastic products. As a core component of the mold cooling system, the design and layout of the mold cooling channels directly affect the cooling rate and temperature distribution of the molten plastic, as well as the residual stress and deformation of the finished product.

[0003] However, in the existing design and application of injection mold cooling channels, there is a common problem of poor cooling effect. Traditional cooling channel layouts mostly adopt simple straight or parallel structures. Such cooling channel structures have a small contact area, poor cooling effect, and low efficiency. Therefore, the cooling channel for injection molds is proposed. Utility Model Content

[0004] The main purpose of this invention is to provide a cooling water channel for injection molding molds, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The injection molding mold cooling channel includes a cooling box, the interior of which is provided with a cooling cavity. A first heat-conducting plate and a second heat-conducting plate are vertically arranged at the bottom of the cooling cavity. Multiple first heat-conducting plates and multiple second heat-conducting plates are provided. One end of the first heat-conducting plate is fixedly connected to one side of the inner side of the cooling cavity, and one end of the second heat-conducting plate is fixedly connected to the other side of the inner side of the cooling cavity. Multiple first heat-conducting plates and multiple second heat-conducting plates are arranged alternately.

[0007] The interior of the cooling cavity is used for the installation and placement of the injection mold. The injection mold has a mold cavity inside. The bottom surface of the injection mold has a groove. There are multiple grooves, which are used for the insertion of the top ends of multiple first heat-conducting plates and multiple second heat-conducting plates.

[0008] By adopting the above technical solution, the first heat-conducting plate and the second heat-conducting plate are alternately arranged and vertically inserted into the groove at the bottom of the injection mold to form an embedded and tightly contacted structure, which greatly increases the effective contact area between the heat-conducting plate and the mold. Heat is directly conducted from the mold cavity through the injection mold to the heat-conducting plate, and then efficiently transferred by the heat-conducting plate to the cooling water flowing through the gap, thereby improving the cooling speed of the mold and significantly shortening the injection molding cycle.

[0009] Specifically, a flow pipe is fixedly connected to one side of the cooling box, and multiple flow pipes are provided, with the interior of the multiple flow pipes communicating with the interior of the cooling chamber.

[0010] By adopting the above technical solution, the flow pipes serve as the key channels for cooling water circulation, leading the high-temperature cooling water after heat absorption out of the cooling chamber. The distribution of multiple flow pipes ensures that the cooling water can flow out of the cooling chamber evenly and efficiently, avoiding local blockages and providing a physical basis for subsequent air-cooled heat dissipation.

[0011] Specifically, one end of each of the multiple flow pipes is fixedly connected to one side of the water tank, the interior of each of the multiple flow pipes is connected to the interior of the water tank, and a one-way valve is fitted onto the outside of each of the multiple flow pipes.

[0012] By adopting the above technical solution, the flow pipe achieves unidirectional flow of cooling water through a one-way valve, that is, only the cooling water that has absorbed heat is allowed to flow from the cooling chamber to the water tank, preventing backflow or reverse flow. This ensures the continuity and stability of the cooling cycle.

[0013] Specifically, a water pump is fixedly installed at the top of the water tank, and the outlet of the water pump is fixedly connected to one side of the cooling tank and communicates with the interior of the cooling cavity.

[0014] By adopting the above technical solution, after the water pump starts, it draws out the low-temperature cooling water from the water tank and injects it into the cooling chamber through the outlet pipe. The water pump provides the power required for system circulation, drives the cooling water to flow in the cooling chamber, and makes full contact with the first heat-conducting plate and the second heat-conducting plate, thereby quickly absorbing the heat conducted from the injection mold.

[0015] Specifically, a cooling fan is fixedly installed at the bottom of the cooling box, and the cooling fan is located directly above multiple flow pipes.

[0016] By adopting the above technical solution, the cooling fan blows air downwards after being turned on, directly acting on the outer surface of the flow pipe. Since the cooling fan is located directly above the flow pipe, its airflow can efficiently cover the pipe area, providing auxiliary air cooling for the high-temperature cooling water in the pipe, accelerating the heat dissipation process, and improving the overall cooling efficiency.

[0017] Specifically, air inlets are provided on opposite sides of the cooling box, and the air inlets are used to supply cooling air to the cooling fan.

[0018] By adopting the above technical solution, the air inlet allows external cold air to be drawn in by the cooling fan, forming an airflow circulation. This cold air exchanges heat with the outer wall of the circulation pipe, carrying away the heat from the pipe surface, thereby further reducing the cooling water temperature. The design of the air inlet ensures the continuous air supply of the air-cooled system and enhances the heat dissipation effect.

[0019] The beneficial effects of this utility model are:

[0020] (1) The injection molding mold cooling water channel of the present invention is formed by the alternating arrangement of the first heat-conducting plate and the second heat-conducting plate and their vertical insertion into the groove at the bottom of the injection mold to form an embedded and tightly contacted structure, which greatly increases the effective contact area between the heat-conducting plate and the mold. Heat is directly conducted from the mold cavity through the injection mold to the heat-conducting plate, and then efficiently transferred by the heat-conducting plate to the cooling water flowing through the gap, thereby improving the cooling speed of the mold and significantly shortening the injection molding cycle.

[0021] (2) The injection molding mold cooling water channel of this utility model is formed by a water pump driving the cooling water to form an S-shaped path in the cooling chamber to fully absorb heat, and then returning to the water tank through a flow pipe controlled by a one-way valve to form an effective water circulation channel.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] As one embodiment of this utility model, such as Figures 1-3 As shown, the injection molding mold cooling channel of this utility model includes a cooling box 5, and a cooling cavity 10 is provided inside the cooling box 5. A first heat-conducting plate 8 and a second heat-conducting plate 9 are vertically arranged at the bottom of the inner side of the cooling cavity 10. Multiple first heat-conducting plates 8 and multiple second heat-conducting plates 9 are provided. One end of the first heat-conducting plate 8 is fixedly connected to one side of the inner side of the cooling cavity 10, and one end of the second heat-conducting plate 9 is fixedly connected to the other side of the inner side of the cooling cavity 10. Multiple first heat-conducting plates 8 and multiple second heat-conducting plates 9 are arranged alternately.

[0029] The interior of the cooling cavity 10 is used for the installation and placement of the injection mold 3. The injection mold 3 has a mold cavity 4 inside. The bottom end face of the injection mold 3 has a groove 12. There are multiple grooves 12, which are used for the insertion of the top ends of multiple first heat-conducting plates 8 and multiple second heat-conducting plates 9.

[0030] When in use, the injection mold 3 is first installed in the cooling chamber 10 inside the cooling box 5. At this time, multiple alternating first heat-conducting plates 8 and second heat-conducting plates 9 will be vertically inserted into multiple grooves 12 opened on the bottom surface of the injection mold 3, which increases the contact area between the heat-conducting plates and the injection mold 3, providing a good foundation for subsequent heat conduction.

[0031] It should be noted that the length of the first heat-conducting plate 8 and the second heat-conducting plate 9 is shorter than the width of the cooling cavity 10.

[0032] This utility model also includes a flow pipe 6 fixedly connected to one side of the cooling box 5. The flow pipe 6 has multiple pipes, and the interior of the multiple flow pipes 6 is connected to the interior of the cooling cavity 10.

[0033] During use, the flow pipe 6 serves as a key channel for cooling water circulation, leading the high-temperature cooling water after heat absorption out of the cooling chamber 10. The distribution of multiple flow pipes 6 ensures that the cooling water can flow out of the cooling chamber 10 evenly and efficiently, avoiding local blockages and providing a physical basis for subsequent air-cooled heat dissipation.

[0034] This utility model also includes that one end of the plurality of flow pipes 6 is fixedly connected to one side of the water tank 2, the interior of the plurality of flow pipes 6 is connected to the interior of the water tank 2, and a one-way valve 13 is sleeved on the outside of the plurality of flow pipes 6.

[0035] During use, the flow pipe 6 achieves unidirectional flow of cooling water through the one-way valve 13, that is, only the cooling water after absorbing heat is allowed to flow from the cooling chamber 10 to the water tank 2, preventing backflow or reverse flow, which ensures the continuity and stability of the cooling cycle.

[0036] The present invention also includes a water pump 1 fixedly installed at the top of the water tank 2, the water outlet of the water pump 1 being fixedly connected to one side of the cooling tank 5 and communicating with the interior of the cooling cavity 10.

[0037] When in use, after the water pump 1 is started, it draws out the low-temperature cooling water from the water tank 2 and injects it into the cooling chamber 10 through the outlet pipe. The water pump 1 provides the power required for the system circulation, and drives the cooling water to flow in the cooling chamber 10, making full contact with the first heat-conducting plate 8 and the second heat-conducting plate 9, thereby quickly absorbing the heat conducted from the injection mold 3.

[0038] The present invention also includes a cooling fan 11 fixedly installed at the bottom of the cooling box 5, and the cooling fan 11 is located directly above the multiple flow pipes 6.

[0039] When in use, the cooling fan 11 blows air downwards after being turned on, directly acting on the outer surface of the flow pipe 6. Since the cooling fan 11 is located directly above the flow pipe 6, its airflow can efficiently cover the pipe area, providing auxiliary air cooling for the high-temperature cooling water in the pipe, accelerating the heat dissipation process, and improving the overall cooling efficiency.

[0040] The present invention also includes air inlets 7 on opposite sides of the cooling box 5, the air inlets 7 being used to supply cooling air to the cooling fan 11.

[0041] During use, the air inlet 7 allows external cold air to be drawn in by the cooling fan 11, forming an airflow circulation. This cold air exchanges heat with the outer wall of the circulation pipe 6, carrying away the heat from the pipe surface, thereby further reducing the cooling water temperature. The design of the air inlet 7 ensures a continuous air supply to the air-cooled system and enhances the heat dissipation effect.

[0042] In use, the injection mold 3 is first installed in the cooling chamber 10 inside the cooling box 5, allowing the first heat-conducting plate 8 and the second heat-conducting plate 9 to be vertically inserted into the groove 12 on the bottom surface of the injection mold 3, greatly increasing the contact area between the heat-conducting plates and the injection mold 3. Then, the water pump 1 is started to draw cooling water from the water tank 2 and inject it into the cooling chamber 10 through a pipe connected to the cooling box 5. Inside the cooling chamber 10, the cooling water makes full contact with the first heat-conducting plate 8 and the second heat-conducting plate 9, and the cooling water flows through the gap between the first heat-conducting plate 8 and the second heat-conducting plate 9, forming an S-shaped flow path within the cooling chamber 10. These heat-conducting plates have excellent thermal conductivity, allowing heat to pass through quickly. The heat is conducted from the mold to the heat-conducting plate, and then from the heat-conducting plate to the cooling water, accelerating the cooling rate and quickly absorbing the heat conducted from the injection mold 3. Since one end of the multiple flow pipes 6 is connected to the cooling chamber 10 and the other end is connected to the water tank 2, and the outside of the pipes is fitted with a one-way valve 13, the cooling water after absorbing heat can only flow back to the water tank 2 through the flow pipes 6 under the action of the one-way valve 13, completing one cooling cycle. During the cooling water cooling cycle, the cooling fan 11 can be turned on. The cooling fan 11 blows air downwards to provide air cooling assistance to the surface of the flow pipes 6. The cold air drawn in from the air inlet 7 exchanges heat with the outer wall of the flow pipes 6, taking away some of the heat and further improving the heat dissipation efficiency of the entire cooling system.
