[0014] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0015] The utility model proposes a mold temperature control device, including a mold 1, a temperature control component 2 is installed on the mold 1, the mold 1 includes a bottom mold 11, a groove 111 is provided at the bottom of the bottom mold 11, the temperature control component 2 includes a tube body 21, the tube body 21 is laid inside the groove 111, the groove 111 is arranged in a serpentine spiral, so that the tube body 21 can better release the heat absorption from the bottom mold 11, and the contact area between the tube body 21 and the bottom mold 11 is increased by providing the groove 111 on the bottom mold 11, so that the cooling liquid inside the tube body 21 can better heat the injection molded part and the mold 1. In order to absorb heat, the two ends of the tube body 21 are connected by a heat dissipation pipe 23, and a gear pump 22 is installed on the pipeline of the tube body 21. The gear pump 22 can drive the coolant circulation inside the tube body 21 and the heat dissipation pipe 23. A cooling fan 24 is correspondingly arranged on one side of the heat dissipation pipe 23. The heat dissipation pipe 23 is composed of a plurality of small pipes. By diverting the coolant inside the pipe, the coolant can be quickly cooled down under the operation of the cooling fan 24. In actual use, in order to prevent the wind generated by the cooling fan 24 from contacting the mold 1, the air outlet end of the cooling fan 24 is arranged away from the mold 1.

[0016] Specifically, the mold 1 also includes a top mold 12, which is arranged on the top of the bottom mold 11. The top of the top mold 12 is connected to an injection tube 121. During injection molding, the top mold 12 is pressed and fixed on the top of the bottom mold 11, and injection plastic is injected into the injection tube 121 so that the injection plastic can enter the cavity of the mold 1 to form the shape of the injection molded part.

[0017] Specifically, a mold cover 112 is provided at the bottom of the bottom mold 11, and flanges 113 are provided between the mold cover 112 and the bottom mold 11. The two flanges 113 are fixedly connected by bolts 1131. The design purpose is to fix the mold cover 112 by the flange 113 and the bolts 1131, and the mold cover 112 can close the bottom mold 11, so that a tight connection can be achieved between the tube body 21 and the bottom mold 11.

[0018] Specifically, a first temperature sensor 25 is arranged on the pipeline of the tube body 21 near the output end of the gear pump 22, and a second temperature sensor 26 is arranged between the bottom mold 11 and the mold cover 112. The first temperature sensor 25 can detect the stability of the coolant after cooling, and the second temperature sensor 26 can detect the temperature at the mold 1, so that the staff can observe and control it.

[0019] Specifically, a liquid injection valve 211 is provided on the pipeline of the tube body 21. The setting of the liquid injection valve 211 can inject coolant into the tube body 21. The two ends of the tube body 21 are fixedly connected by a mounting frame 3. The refrigeration fan 24 is installed on the side of the mounting frame 3 corresponding to the tube body 21. The mounting frame 3 is used to fix the refrigeration fan 24, the tube body 21 and the heat dissipation pipe 23.

[0020] According to the personnel in this field, all the electrical parts and components in this case are universal standard parts or components known to the technical personnel in this field, and their structures and principles can be known to the technical personnel through technical manuals or through conventional experimental methods. The models are compatible with this solution and can operate normally. All the electrical parts in this case are connected to the power supply adapted to them through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection is completed in the working order of each electrical component. The detailed connection means are well-known technologies in this field and will not be explained in the electrical control.

[0021] Working principle: When the mold is in use, an appropriate amount of coolant can be injected into the tube body 21 through the injection valve 211, and then the bottom mold 11 and the top mold 12 are pressed and fixed, and high-temperature injection plastic is injected into them through the injection tube 121. After the injection is completed, the gear pump 22 and the cooling fan 24 can be started. The operation of the gear pump 22 can drive the coolant inside the tube body 21 to circulate, so that the tube body 21 can transfer the heat of the injection plastic to the mold 1. The heat can pass through the heat dissipation pipe 23. At this time, the cooling fan 24 can blow cold air to the heat dissipation, and the heat dissipation pipe 23 composed of multiple small pipes can divert the coolant with heat, so that the cold air of the cooling fan 24 can better transfer heat with the heat dissipation pipe 23 and the coolant. After the heat of the injection plastic and the mold 1 is absorbed, the injection molded part can be quickly demolded, which greatly improves the demolding efficiency of the injection molded part.
