[0027] Example

[0028] In existing technologies, existing molds generally suffer from slow cooling rates. The molds need to wait for a long time for the internal temperature to drop to the set range, resulting in low demolding efficiency, increased product defect rate, and serious energy waste.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a mold device for rapid demolding, including a lower mold assembly 10, the lower mold assembly 10 including a lower mold plate 13, a controller 14, a liquid inlet pipe 19, a solenoid valve 110, a diverter pipe 111, a heat exchange pipe 112, a heat conduction plate 113, a spiral guide plate 114, a manifold pipe 115, a liquid outlet pipe 116 and a temperature sensor 117;

[0030] A controller 14 is mounted on the front surface of the lower template 13. An inlet pipe 19 is fixedly connected to the inner wall of the lower template 13. A solenoid valve 110 is mounted on the inlet pipe 19. One end of the inlet pipe 19 is connected to a diversion pipe 111. Heat exchange pipes 112 are evenly connected to the outer wall of the diversion pipe 111. A heat-conducting plate 113 is fixedly connected to the outer wall of the heat exchange pipe 112. A spiral guide plate 114 is fixedly connected to the inner wall of the heat exchange pipe 112. One end of the heat exchange pipe 112 is connected to a manifold 115. One end of the manifold 115 is connected to an outlet pipe 116. A [missing information - likely a device or component] is mounted on the outlet pipe 116. Temperature sensor 117. Molten raw material is injected into the mold cavity, which is formed by the mold cavity 15 and the upper mold plate 24, through the injection port 22. After injection, the cooling system is activated, and the controller 14 opens the solenoid valve 110. Coolant enters the distribution pipe 111 through the inlet pipe 19, and is then evenly distributed to each heat exchange pipe 112. Inside the heat exchange pipe 112, the spiral guide plate 114 forces the coolant into a turbulent state, increasing the contact time and area between the fluid and the pipe wall. At the same time, the heat conduction plate 113 is tightly attached to the outer wall of the heat exchange pipe 112, transferring heat from the mold cavity to the coolant flowing inside the pipe. After heat exchange, the coolant collects in the manifold 115 and is discharged through the outlet pipe 116. Temperature sensor 117 monitors the outlet temperature in real time. When the detected value reaches the preset threshold, the controller 14 immediately closes the solenoid valve 110.

[0031] In this embodiment, specifically: the bottom of the lower template 13 is fixedly connected to a lower mold base 11, and the lower mold base 11 is installed on the support surface.

[0032] In this embodiment, specifically: the top of the lower mold base 11 is symmetrically and fixedly connected with a guide sleeve 12, and the guide sleeve 12 matches the size of the guide post 23.

[0033] In this embodiment, specifically: a cavity 15 is provided at the top of the lower template 13, and the material is cooled and formed in the mold cavity jointly formed by the cavity 15 and the upper template 24.

[0034] In this embodiment, specifically: a top plate 16 is provided on the top of the lower mold base 11, and a push rod 17 is symmetrically fixedly connected to the top of the top plate 16. A spring 18 is sleeved on the outer side wall of the push rod 17. The top plate 16 is driven upward by a hydraulic device to push the push rod 17 to smoothly push the molded product out of the cavity 15, thereby achieving demolding. The spring 18 is used to reset the top plate 16.

[0035] In this embodiment, specifically: an upper mold assembly 20 is provided on the top of the lower mold assembly 10, and the upper mold assembly 20 includes an upper mold base 21 and an injection port 22;

[0036] The top of the lower mold plate 13 is provided with an upper mold base 21, and the top of the upper mold base 21 is provided with an injection port 22. Molten raw material is injected into the mold cavity formed by the cavity 15 and the upper mold plate 24 through the injection port 22.

[0037] In this embodiment, specifically: the bottom of the upper mold base 21 is symmetrically and fixedly connected with guide posts 23, the guide posts 23 are sleeved inside the guide sleeve 12, and the outer side wall of the guide post 23 is slidably connected to the inner side wall of the guide sleeve 12, so as to ensure that the upper mold base 21 is more stable when moving up and down and is less prone to displacement.

[0038] In this embodiment, specifically: the bottom of the upper mold base 21 is fixedly connected to the upper template 24, and after the mold is closed, the upper template 24 is in close contact with the lower template 13.

[0039] Working principle or structural principle: The injection molding machine drives the upper mold assembly 20 to move downwards, and the guide post 23 is inserted into the guide sleeve 12 on the lower mold base 11 to ensure that the upper mold plate 24 and the lower mold plate 13 are tightly closed. Molten raw material is injected into the mold cavity formed by the cavity 15 and the upper mold plate 24 through the injection port 22. After injection molding is completed, the cooling system is started, and the controller 14 opens the solenoid valve 110. The coolant enters the distribution pipe 111 through the inlet pipe 19, and is then evenly distributed to each heat exchange pipe 112. Inside the heat exchange pipe 112, the spiral guide plate 114 forces the coolant into a turbulent state, increasing the contact time and area between the fluid and the pipe wall. At the same time, the heat conduction plate 113 is tightly attached to the outer wall of the heat exchange pipe 112, transferring the heat of the mold cavity to the coolant flowing inside the pipe. After heat exchange, the coolant collects in the manifold 115 and is discharged through the outlet pipe 116. Temperature sensor 117 monitors the outlet temperature in real time. When the detected value reaches the preset threshold, controller 14 immediately closes solenoid valve 110 to cut off the coolant supply and avoid energy waste caused by ineffective circulation. Once the mold temperature drops to the demolding requirement, the injection molding machine moves the upper mold assembly 20 upward, and the ejector plate 16 is driven upward by hydraulic equipment to push the ejector rod 17 to smoothly eject the molded product from the cavity 15, thus achieving demolding.

[0040] In summary, this invention, through the design of heat exchange tube 112, heat conduction plate 113, and spiral guide plate 114, effectively improves the heat exchange efficiency of the coolant and accelerates the heat transfer and dissipation inside the mold. Through the coordinated use of controller 14, solenoid valve 110, and temperature sensor 117 in the lower mold assembly 10, the coolant inlet can be automatically stopped according to the coolant outlet temperature, achieving precise control and circulation of the coolant, effectively saving energy. The coolant circulation method can be connected to an external cooling machine.
