Description

Technical Field

[0001] This utility model relates to a mold heating and heat dissipation circuit suitable for injection molding machines. Background Technology

[0002] Injection molding is one of the most widely used plastic molding methods. In the injection molding process, molten plastic is injected into a mold cavity to give it a certain shape, and then cools and solidifies within the mold cavity. Since the molding and cooling of the molten plastic are all completed within the mold cavity, mold cavity temperature control has a significant impact on the quality of the final injection-molded product and the molding cycle. Mold temperature is also one of the most important parameters in the injection molding process.

[0003] A search revealed that prior art publication number CN211363357U discloses a rapid heating and cooling system for injection molds, including a fixed mold base plate. A guide post is located at the upper end of the fixed mold base plate, and a fixed mold core is located on the inner side of the upper end of the fixed mold base plate near the guide post. A moving mold plate is located on the outer side of the guide post. Two sets of connecting mechanisms are located at one end of the fixed mold core, and a cooling water outlet pipe is located at one end of each connecting mechanism. A circulating water pump is located at one end of the cooling water outlet pipe, and a water storage tank is located on the outer side of the circulating water pump. A fixing groove is located inside the moving mold plate, and a spiral resistance wire is located inside the fixing groove. A fixing plate is located at the upper end of the fixing groove. This rapid heating and cooling system for injection molds provides good sealing between the cooling water outlet pipe and the fixed mold core, reducing leakage and improving heating efficiency. It also facilitates the replacement of the spiral resistance wire inside the fixing groove. However, it lacks monitoring, making it prone to damage over prolonged operation.

[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a new type of mold heating and heat dissipation circuit suitable for injection molding machines, making it more valuable for industrial applications. Utility Model Content

[0026] Example

[0027] like Figures 1 to 6As shown, a mold heating and heat dissipation circuit suitable for injection molding machines includes a main circuit unit 1. The output terminal of the main circuit unit 1 is connected to the input terminal of a control power supply unit 2. The output terminal of the control power supply unit 2 is connected to the input terminal of a control unit 3. The input terminal of the control unit 3 is connected to the output terminal of a heater 4 via a temperature sensor. The input terminal of the control unit 3 is connected to the output terminal of a water-cooled heat exchanger 5 via a temperature sensor. The output terminal of the control unit 3 is connected to the input terminal of a controller 6. The output terminal of the main circuit unit 1 is connected to the input terminal of an IGBT unit 8. The output terminal of the IGBT unit 8 is connected to the input terminal of a drive unit 9. The output terminal of the drive unit 9 is connected to the input terminal of the heater 4. The output terminal of the drive unit 9 is connected to the input terminal of a circulating pump. The heater is connected to the water-cooled heat exchanger 5 via the circulating pump.

[0028] In this invention, the output terminal of the control unit 3 is connected to the input terminal of the alarm unit 7.

[0029] The control power supply unit 2 described in this utility model provides DC24V and DC15V.

[0030] In this invention, the control unit 3 is connected to the controller 6 via RS232 or RS485 communication.

[0031] The controller 6 described in this utility model is an industrial computer, model number MT6103IP.

[0032] In this utility model, the control unit 3 is a control panel, which is connected to an alarm interface, a temperature sensor interface, a DC24V power supply interface, and a communication interface.

[0033] The drive unit 9 described in this utility model is a drive board, model number 4DM5-SV1.5. The drive board is connected to a DC24V interface, an IGBT interface, and a connection interface to the back end.

[0034] The working principle of this utility model is as follows:

[0035] In actual operation, the heater heats the product and monitors it through a temperature sensor. The controller uses the data from the temperature sensor to adjust whether the water-cooled heat exchanger cools the heater. If the set temperature is reached, water-cooled heat exchange is performed; otherwise, monitoring continues.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0037] In the description of this application, it should be noted that the terms "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0038] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0039] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly.
