The first module and the second module can approach each other and form a docking. A limit member that can limit the separation of the first module and the second module is arranged between the upper mold and the base plate.

[0004] The above patent has the following deficiencies: after the injection molding machine injects the hot plastic melt into the cavity between the upper mold and the lower mold, it is necessary to wait for the melt to cool naturally to form. The cooling time is long, which affects the overall work efficiency, and it is easy to cause deformation due to insufficient cooling. Utility Model Content

The first mold is fixed on the top of the bracket, guide rods are symmetrically fixed on both sides of the top of the first mold, a support plate is fixed between the tops of the four guide rods, the second mold is slidably connected between the four guide rods, an injection molding tube is connected to the right side of the top of the second mold, a cylinder is installed on the support plate, the cylinder telescopic rod is connected to the second mold, a heat dissipation plate for storing coolant is fixed on the outside of the first mold, and a circulation component for conveying coolant is provided on the bracket.

[0007] Furthermore, the first mold moves downward to seal and contact with the second mold, thereby forming a cavity for injecting plastic melt.

[0008] Furthermore, the circulation component includes a water pump, a cooling box and a second cooling fan. A cooling box for storing coolant is fixed on the lower side of the bracket. Water pumps for pumping coolant are symmetrically installed on the front side of the cooling box. Water inlet pipes of the two water pumps are connected to the cooling box, and water outlet pipes of the two water pumps are connected to the heat sink. A second cooling chamber is opened on the left side of the cooling box, and a first cooling chamber is opened on the right side of the cooling box. Second cooling fans for cooling the liquid inside the cooling box are symmetrically installed on both sides of the bracket, and the second cooling fan is located outside the cooling box.

[0009] Furthermore, the water inlet pipes of the two water pumps are communicated with the second cooling chamber and the first cooling chamber respectively.

[0010] Furthermore, the two water pumps can respectively pump the coolant in the second cooling chamber and the first cooling chamber for rotation use.

[0011] Furthermore, a first cooling fan is included, and the first cooling fans are evenly installed on the support plate.

[0012] The beneficial effects of the utility model are as follows: 1. The water pump draws the coolant into the heat sink, which can dissipate the heat of the molten liquid in the cavity between the first mold and the second mold, accelerate the molding of the plastic product, and improve the overall work efficiency;

[0013] 2. The first cooling chamber and the second cooling chamber in the cooling box store coolant, which can be alternately injected into the heat sink for use, ensuring that the injection molding work is carried out continuously and orderly. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] Embodiment: An injection mold with heat dissipation function, such as Figure 1-Figure 2 As shown, it includes a bracket 1, a first mold 2, a second mold 3, an injection tube 31, a support plate 4, a cylinder 5, a guide rod 6, a heat sink 8 and a circulation component. The first mold 2 is fixed on the top of the bracket 1, and guide rods 6 are fixed symmetrically on the left and right sides of the top of the first mold 2. A support plate 4 is fixed between the tops of the four guide rods 6. The second mold 3 is slidably connected between the four guide rods 6. The injection tube 31 is connected to the right side of the top of the second mold 3. The cylinder 5 is installed on the support plate 4. The telescopic rod of the cylinder 5 is connected to the second mold 3. The first mold 2 moves downward and contacts with the second mold 3 in a sealed manner to form a cavity for injecting plastic melt. A heat sink 8 for storing coolant is fixed on the outside of the first mold 2, and a circulation component for conveying coolant is provided on the bracket 1.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, the circulation component includes a water pump 9, a cooling box 10 and a second cooling fan 11. A cooling box 10 for storing coolant is fixed on the lower side of the bracket 1. Water pumps 9 for pumping coolant are symmetrically installed on the front side of the cooling box 10. The water inlet pipes of the two water pumps 9 are connected to the cooling box 10, and the water outlet pipes of the two water pumps 9 are connected to the heat sink 8. A second cooling chamber 102 is opened on the left side of the cooling box 10, and a first cooling chamber 101 is opened on the right side of the cooling box 10. The water inlet pipes of the two water pumps 9 are respectively connected to the second cooling chamber 102 and the first cooling chamber 101. Second cooling fans 11 for cooling the liquid inside the cooling box 10 are symmetrically installed on both sides of the bracket 1, and the second cooling fan 11 is located outside the cooling box 10.

[0022] like Figure 1 As shown, a first cooling fan 7 is also included, and four first cooling fans 7 are evenly installed on the support plate 4.

[0023] When performing injection molding production, first start the water pump 9 on the left side. The water pump 9 will pump the coolant in the second cooling chamber 102 into the heat sink 8. After the pumping is completed, turn off the water pump 9, and then start the cylinder 5 to extend the telescopic rod of the cylinder 5 to drive the second mold 3 to move downward. After the second mold 3 moves down and presses the first mold 2, pause the cylinder 5, and then connect the injection molding machine to the injection molding tube 31, and inject the plastic melt into the cavity between the second mold 3 and the first mold 2 through the injection molding tube 31. After the injection is completed, separate the injection molding machine from the injection molding tube 31, and wait for the plastic product to cool and form. The heat sink 8 is attached to the first mold 2, and the coolant in the heat sink 8 will cool the plastic product. The staff can also turn on the first cooling fan 7, and the first cooling fan 7 will blow the wind downward. The heat generated outside the first mold 2 and the second mold 3 will be blown away by the first cooling fan 7, which plays a role in heat dissipation. After the plastic product is cooled and formed, the telescopic rod of the cylinder 5 can be controlled Shorten the reset so that the cylinder 5 drives the second mold 3 to move upward and out of contact with the first mold 2. After the injection molding process is completed, the finished product can be removed from the first mold 2. The plastic product processing can be continued according to the above operation method. After the coolant in the heat sink 8 has been used for a period of time, when the cooling effect is not good enough, the water pump 9 on the left can be started to pump the liquid in the heat sink 8 back to the second cooling chamber 102. After pumping, the water pump 9 on the left can be turned off, and then the water pump 9 on the right can be started to pump the coolant in the first cooling chamber 101 into the heat sink 8. After pumping, the water pump 9 is turned off, and then the second cooling fan 11 is turned on. The second cooling fan 11 will dissipate the heat of the coolant in the cooling box 10, speed up the cooling speed of the used coolant, and the coolant in the first cooling chamber 101 and the second cooling chamber 102 can be used alternately without affecting the normal heat dissipation function, thereby improving the heat dissipation quality of the coolant and speeding up the processing efficiency of plastic products.
