Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold with intelligent mold temperature control. Background Art

[0002] Injection molds are the main molding equipment for making plastic products of various shapes from thermoplastics or thermosetting plastics using plastic molding molds. It is very important to control the temperature of the mold during the injection molding process. Too low a temperature will cause the mold to be formed too quickly, resulting in uneven hardness inside and outside the mold. Too high a temperature will cause the mold to be formed too slowly, so the temperature inside the mold needs to be controlled.

[0003] According to a publicly disclosed injection mold temperature control system (publication number: CN217258189U), the above application is provided with a first water tank and a second water tank. The first water tank contains coolant, which is connected to the lower mold through the second conduit to cool it down. The second water tank contains hot water, which is connected to the lower mold through the first conduit to heat it, so that the temperature of the mold can be conveniently controlled according to needs.

[0004] However, during actual use of the above-mentioned equipment, when the flowing water circulates inside the heat pipe, the heat exchange efficiency of the flowing water far away from the inner wall of the heat pipe is lower than the heat exchange efficiency of the flowing water close to the inner wall of the heat pipe, resulting in that the temperature control performance of the flowing water at the center of the heat pipe cannot be fully utilized, thereby affecting the speed and efficiency of the temperature control inside the mold; in view of this, we propose an injection mold with intelligent mold temperature control.

DETAILED DESCRIPTION

[0023] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: an injection mold with intelligent mold temperature control, comprising a lower mold 1, a fixing frame 2 is fixedly installed on the upper end of the lower mold 1, an upper mold 3 is arranged on the inner top surface of the fixing frame 2, and a temperature control component 4 is arranged on the outer side of the lower mold 1, and the temperature control component 4 comprises: a connecting pipe, a cold water storage tank, a hot water storage tank and a water pump, the interiors of the cold water storage tank and the hot water storage tank are both connected to the interior of a circulation pipe 5 through a connecting pipe, and a refrigerator and a heater are respectively arranged inside the cold water storage tank and the hot water storage tank to cool and heat water, when the water pump is started, hot water or cold water can enter the interior of the circulation pipe 5 for circulation, thereby controlling the temperature inside the lower mold 1, and a circulation pipe 5 is arranged inside the lower mold 1, and a flow guide component is arranged inside the circulation pipe 5.

[0024] The flow guide assembly includes: a hollow tube 601, an annular plate 604 and a flow guide hopper 607. The hollow tube 601 is arranged inside the circulation pipe 5. The hollow tube 601 can restrict the water entering the circulation pipe 5 so that the water flows along the inner wall of the circulation pipe 5. Compared with the original circulation pipe 5, the same amount of water can pass through the inner wall of the circulation pipe 5 for a longer time, thereby enhancing the heat exchange efficiency. In addition, the water at the center of the cross section of the original circulation pipe 5 is closer to the inner wall of the circulation pipe 5 than the water at the center of the cross section of the circulation pipe 5. The heat exchange rate of flowing water is low, and this part of the flowing water can be better utilized after limiting. The interior of the hollow tube 601 is filled with foam plastic 602, and the foam plastic 602 can insulate the interior of the hollow tube 601 to reduce the impact of the hollow tube 601 on the heat of the flowing water. A fixing rod 603 is fixedly installed on the outside of the hollow tube 601, and the end of the fixing rod 603 away from the hollow tube 601 is fixedly connected to the inner wall of the circulation pipe 5, and the hollow tube 601 is fixed to the inside of the circulation pipe 5 by the fixing rod 603.

[0025] The annular plate 604 is fixedly installed on the outside of the hollow tube 601, and a drainage hole 605 is provided on the right surface of the annular plate 604. An elastic member 606 is fixedly installed on the left surface of the annular plate 604. A guide bucket 607 is fixedly installed on the left end of the elastic member 606. The inner wall of the guide bucket 607 fits the outer wall of the hollow tube 601. The outer wall diameter of the guide bucket 607 is the same as the outer wall diameter of the annular plate 604. The left surface of the guide bucket 607 is near the water surface. When the water flows in the circulation pipe 5, it will flow to the right along the left inclined surface of the guide bucket 607. When the water flows through the guide bucket 607, the water on the side away from the inner wall of the circulation pipe 5 will flow along the left surface of the guide bucket 607 to the side close to the inner wall of the circulation pipe 5, thereby enhancing the mixing efficiency between the water flows, so that the water flows to the lower mold 1. The temperature control of the wall is faster and more accurate. A water hole 608 is provided on the left surface of the guide bucket 607. When water flows through the guide bucket 607, part of the water will flow normally through the water hole 608, thereby reducing the pressure of the guide bucket 607. At the same time, when the water impacts the guide bucket 607, it will push the guide bucket 607 to move to the right, thereby squeezing the elastic member 606 to generate elastic potential energy, buffering and offsetting the impact force on the guide bucket 607, and extending the service life of the guide bucket 607. Part of the water passing through the water hole 608 will enter the gap between the guide bucket 607 and the annular plate 604. At this time, the part of the water will be discharged through the drainage hole 605 and continue to flow to the right, thereby avoiding part of the water staying in the gap between the guide bucket 607 and the annular plate 604, which affects the circulation effect of the water.

[0026] Guide grooves 701 are provided at the upper and lower ends of the outer surface of the hollow tube 601, and a guide block 702 is slidably connected inside the guide groove 701. The side surface of the guide block 702 away from the hollow tube 601 is fixedly connected to the inner wall of the guide bucket 607. The movement of the guide bucket 607 can be guided and limited by the cooperation of the set guide groove 701 and the guide block 702, so as to prevent the guide bucket 607 from deviating during the movement and getting stuck on the outside of the hollow tube 601, causing the elastic member 606 and the annular plate 604 to lose their function, thereby affecting the service life of the guide assembly.

[0027] In the present invention, when the water circulates in the circulation pipe 5 to control the temperature inside the lower mold 1, the hollow tube 601 will limit the water flow so that the water flows along the inner wall of the circulation pipe 5 to enhance the heat exchange efficiency of the water flow. At the same time, the guide bucket 607 can guide the water flow on the side away from the inner wall of the circulation pipe 5 to flow to the side close to the inner wall of the circulation pipe 5 for mixing and circling, thereby enhancing the mixing efficiency between the water flows and improving the overall heat exchange efficiency of the water flow. When hitting the left side of the guide bucket 607, the guide bucket 607 will be squeezed to flow to the right and the elastic part 606 will be compressed to generate elastic potential energy, so as to buffer and offset the impact force on the guide bucket 607. At the same time, part of the water will flow normally through the water hole 608, which can extend the service life of the guide bucket 607. After the water passes through the water hole 608, it can be discharged through the drainage hole 605 and continue to flow to the right, so as to avoid remaining in the gap between the guide bucket 607 and the annular plate 604, which will affect the circulation effect of the water.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
