Description

Technical Field

[0001] This utility model relates to the field of injection molding machines, specifically a plastic injection molding machine with rapid temperature control function. Background Technology

[0002] When processing sleeve workpieces with an injection molding machine, the sleeve is a typical rotating body and thin-walled cylindrical part. It is produced in large batches and has low dimensional accuracy requirements. When processing with an injection molding machine, as long as you grasp the four links of "one input (material), two molds (mold), three machine (process), and four demolding", you can make stable and low-cost mass production of the seemingly simple structure.

[0003] After the mold is closed, the injection molding machine injects the raw material into the mold, and then waits for the raw material in the mold to cool naturally and complete plasticization before taking the material out of the mold. This processing method has low cooling efficiency, which affects the output. Therefore, a plastic injection molding machine with rapid temperature control function is proposed to address the above problems. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model proposes a plastic injection molding machine with rapid temperature control function.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a plastic injection molding machine with rapid temperature control function, including an injection molding machine, a lower mold fixedly connected to the operating table of the injection molding machine, a valve component two fixedly connected to the bottom of the lower mold, a drain pipe fixedly connected to the end of the valve component two for liquid discharge, the rod of the valve component two penetrating and fixedly connected to the rod of the pressure plate component, the end of the pressure plate component fixedly connected to one end of the linkage rod, the other end of the linkage rod fixedly connected to the end of the valve component one, one side of the valve component one fixedly connected to the rear side of the lower mold, the other side of the valve component one fixedly connected to one end of the infusion pipe, the other end of the infusion pipe fixedly connected to the inlet of the water tank, and a support frame fixedly connected to the frame of the injection molding machine for placing the water tank;

[0006] Preferably, the lower mold includes: a receiving chamber, a liquid outlet, and a liquid inlet. The receiving chamber is located in the middle of the lower mold, and the liquid inlet is located on the rear side of the receiving chamber. The liquid inlet is connected to a valve component one. The liquid outlet is located at the bottom of the receiving chamber and is connected to a valve component two.

[0007] Preferably, the valve component one includes: a positioning cylinder one, an infusion port, a sliding port, and a valve core one. The positioning cylinder one is provided on one side of the valve component one and communicates with the infusion port. The infusion port one is provided on the other side of the valve component one and connects to the infusion tube. The sliding port one is provided at the bottom of the valve component one. The valve core one is slidably connected to the cavity of the valve component one.

[0008] Preferably, the valve core includes: a gasket and a pull rod, with the gasket fixedly connected to the side of the valve core and the end of the pull rod fixedly connected to the bottom of the valve core;

[0009] Preferably, the valve component two includes: a positioning cylinder two and a valve core two. The upper part of the valve component two is fixedly connected to the positioning cylinder two, the opening of the positioning cylinder two is fixedly connected to the bottom of the lower mold, and the cavity of the valve component two is slidably connected to the valve core two.

[0010] Preferably, the valve core two includes: a gasket two and a liquid outlet pipe, with the gasket two fixedly connected to the outer side of the valve core two and the liquid outlet pipe fixedly connected to the middle part of the valve core two;

[0011] Preferably, the liquid outlet tube includes a guide hole and a limiting handle. The guide hole is provided in the tube body of the liquid outlet tube, and the side of the liquid outlet tube is fixedly connected to the end of the limiting handle.

[0012] The advantages of this utility model are:

[0013] 1. This utility model can precisely control the downward pull of the liquid outlet pipe by setting a limiting handle on the liquid outlet pipe rod body. By storing water in the container, the mold on the lower mold is cooled down, the molding of the mold workpiece is accelerated, and the production efficiency is improved.

[0014] 2. This utility model utilizes the downward pull of the pressure plate when valve part two is opened, which causes valve part one to close, preventing water from entering the receiving chamber. The water in the receiving chamber flows out through valve part two, thus venting the water before mold closing. When it is necessary to control the temperature of the mold during mold closing, the pressure plate causes valve part two to close, causing valve part one to release water into the receiving chamber. The water flow relies on the water pressure of the water tank height, so the water pressure will not be too high, thereby avoiding water leakage due to excessive water pressure.

One side of the valve component 1 is fixedly connected to the rear side of the lower mold 2. The other side of the valve component 1 is fixedly connected to one end of an infusion pipe 61. The other end of the infusion pipe 61 is fixedly connected to the connector of a water tank 6. The frame of the injection molding machine 1 is fixedly connected to a support frame 5 for placing the water tank 6.

[0027] The lower mold 2 includes: a receiving chamber 21, a liquid outlet 22, and a liquid inlet 23. The receiving chamber 21 is provided in the middle of the lower mold 2, and the liquid inlet 23 is provided on the rear side of the receiving chamber 21. The liquid inlet 23 is connected to valve component 7. The liquid outlet 22 is provided at the bottom of the receiving chamber 21 and is connected to valve component 8.

[0028] The valve component 7 includes: a positioning cylinder 71, an infusion port 72, a sliding port 73, and a valve core 74. The positioning cylinder 71 is provided on one side of the valve component 7 and communicates with the infusion port 23. The infusion port 72 is provided on the other side of the valve component 7 and connects to the infusion tube 61. The sliding port 73 is provided at the bottom of the valve component 7. The valve core 74 is slidably connected to the cavity of the valve component 7.

[0029] The valve core 74 includes: a gasket 741 and a pull rod 742. The gasket 741 is fixedly connected to the side of the valve core 74, and the end of the pull rod 742 is fixedly connected to the bottom of the valve core 74.

[0030] The valve component 2 8 includes: positioning cylinder 2 81 and valve core 2 82. The upper part of the valve component 2 8 is fixedly connected to the positioning cylinder 2 81, the opening of the positioning cylinder 2 81 is fixedly connected to the bottom of the lower mold 2, and the cavity of the valve component 2 8 is slidably connected to the valve core 2 82.

[0031] The valve core 82 includes: a gasket 821 and a liquid outlet pipe 822. The gasket 821 is fixedly connected to the outer side of the valve core 82, and the liquid outlet pipe 822 is fixedly connected to the middle part of the valve core 82.

[0032] The liquid outlet tube 822 includes a guide hole 801 and a limiting handle 802. The guide hole 801 is provided in the tube body of the liquid outlet tube 822, and the side of the liquid outlet tube 822 is fixedly connected to the end of the limiting handle 802.

[0033] Working principle: Before injection molding in injection molding machine 1, water needs to be injected into water tank 6. Then, the water in water tank 6 flows from a high position into valve component 7 through infusion pipe 61. The middle cavity of valve component 7 is in contact with valve core 74. Positioning cylinder 71 and infusion hole 72 are respectively set on both sides of the lower part of the cavity of valve component 7. When the pull rod 742 moves down, the pull rod 742 slides under the restriction of sliding hole 73. The pull rod 742 drives valve core 74 from valve component 7. The upper part of the cavity moves close to the inner wall to the center point between the infusion hole 72 and the positioning cylinder 71, thereby blocking the water flowing in through the infusion hole 72. This prevents water from flowing into the receiving chamber 21 through the positioning cylinder 71. The end of the pull rod 742 is fixedly connected to the linkage rod 31, which is fixedly connected to the plate of the pressure plate 3. The pressure plate 3 is fixedly connected to the outer wall of the outlet pipe 822. Pulling the pressure plate 3 controls the synchronous upward movement of the outlet pipe 822 and the pull rod 742. Alternatively, it may move downwards. When the pressure plate 3 controls the downward movement of the outlet pipe 822, the valve core 82 is driven downwards. The valve core 82 moves from the positioning cylinder 81 into the cavity of the valve component 8. Because the inner diameter of the valve component 8 is larger than that of the positioning cylinder 81, when the valve core 82 moves into the valve component 8, it can no longer block the positioning cylinder 81. Water in the receiving chamber 21 flows into the cavity of the valve component 8 from the outlet hole 22, and then the water is guided... Water flows into the outlet pipe 822 through the hole 801, and the outlet pipe 822 is connected to the drain pipe 4. The water remaining in the container 21 is drained out. In this way, when the injection molding machine 1 closes the mold, the temperature of the lower mold 2 will not affect the mold closing operation. The limit handle 802 set on the rod of the outlet pipe 822 can precisely control the downward pull of the outlet pipe 822. By storing water in the container 21, the mold on the lower mold 2 is cooled down, the molding of the mold workpiece is accelerated, and the production efficiency is improved.

[0034] When valve 28 is opened, the pressure plate 3 is pulled down, causing valve 17 to close, preventing water from entering the receiving chamber 21. The water in the receiving chamber 21 flows out through valve 28, thus venting the water before mold closing. When it is necessary to control the cooling of mold 2, the pressure plate 3 causes valve 28 to close, causing valve 17 to release water into the receiving chamber 21. The water flow relies on the water pressure of the water tank 6, so the water pressure will not be too high, thus avoiding water leakage due to excessive water pressure.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
