[0048] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a temperature-controllable injection mold.

[0049] A temperature-controllable injection mold includes a first injection body 1 and a second injection body 2, and a heating mechanism disposed within the first injection body 1 and the second injection body 2 for heating operations; and a cooling mechanism disposed within the first injection body 1 and the second injection body 2 for cooling operations. The cooling mechanism includes: a first cooling circulation assembly 3 disposed on the first injection body 1 for coolant circulation; a second cooling circulation assembly 4 disposed on the second injection body 2 for coolant circulation; multiple cooling channels 5 disposed within the first injection body 1 and the second injection body 2 for coolant inflow; multiple electromagnetic flow meters 6 disposed on the first injection body 1 and the second injection body 2 for controlling the coolant flow rate; and multiple temperature sensors 7 disposed within the first injection body 1 and the second injection body 2 for temperature monitoring.

[0050] refer to Figure 2 and Figure 3 In a preferred embodiment, the heating mechanism includes: a heating device disposed within the first injection molding body 1 and the second injection molding body 2 for heating operations; and an injection molding device disposed within the first injection molding body 1 and the second injection molding body 2 for injection operations.

[0051] refer to Figure 2 and Figure 5 In a preferred embodiment, the heating device includes: two mounting slots 8, which are respectively disposed in the first injection molding body 1 and the second injection molding body 2 for component installation; two heat insulation plates 9, which are disposed in the mounting slots 8 and fixedly connected to the mounting slots 8; a temperature control component 12, disposed on the first injection molding body 1 for temperature control; and a control panel 13, disposed on the first injection molding body 1 for operation control.

[0052] refer to Figure 4 and Figure 5 In a preferred embodiment, the heating device further includes: a heating plate 10 disposed on the heat insulation plate 9 for heating operation; and multiple heat dissipation plates 11 disposed on the heating plate 10 for dispersing heat.

[0053] refer to Figure 2 In a preferred embodiment, the injection molding device includes: a support base 14, which is disposed on the first injection body 1 and fixedly connected to the first injection body 1; and an injection hole 15, which is disposed on the second injection body 2 and used for injection molding.

[0054] refer to Figure 1 and Figure 4In a preferred embodiment, the injection molding device further includes: a fixed mold 16 disposed within the first injection body 1 and fixedly connected to the first injection body 1; a movable mold 17 disposed within the second injection body 2 and fixedly connected to the second injection body 2; multiple hydraulic cylinders 18 disposed within the first injection body 1 for moving the second injection body 2; and multiple fixing rods 19 disposed on the second injection body 2 and fixedly connected to the second injection body 2.

[0055] In this configuration, the heating plate 10 and cooling channel 5 are controlled independently, facilitating real-time temperature adjustment of different areas. The electromagnetic flow meter 6 controls the flow rate and volume of the coolant. The temperature control component 12 uses a PLC controller with a built-in PID adaptive adjustment algorithm and machine learning model. It can receive real-time data from the temperature detection module, compare it with the preset temperature curve, and output control signals to the heating / cooling actuators for temperature adjustment. The heat sink 11 accelerates the diffusion of heat from the heating plate 10 into the mounting slot 8 for heating while preventing local overheating. The heat insulation plate 9 prevents heat waste. The first cooling circulation component 3 and the second cooling circulation component 4 can be connected to the electromagnetic flow meter 6 for coolant delivery and recycling.

[0056] This device, by incorporating both heating and cooling mechanisms, achieves rapid temperature control through their coordinated operation, preventing overheating or undercooling of finished parts within the mold and thus avoiding scrapping. Furthermore, by utilizing machine learning models, the device optimizes temperature control strategies based on accumulated production data, reducing manual adjustments and improving production efficiency.

[0057] Working principle: During injection molding, this device monitors the temperature of the fixed mold 16 and the moving mold 17 using multiple temperature sensors 7. When an abnormal temperature is detected, the temperature control component 12 adjusts the heating plate 10 and electromagnetic flow meter attached to the temperature sensor 7 to perform coordinated heating and cooling, thus compensating for temperature and ensuring uniform temperature during operation. This prevents the fixed mold 16 or the moving mold 17 from overheating or overcooling. During heating, the power of the heating plate 10 is increased to allow it to heat up quickly, and the heat dissipation plate 11 dissipates heat quickly, thereby raising the temperature. At the same time, the corresponding electromagnetic flow meter 6 reduces the flow of coolant.

[0058] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
