Description

Technical Field

[0001] The utility model relates to the technical field of motor molding, in particular to a motor accessory molding die which is convenient for heat dissipation. Background Art

[0002] A motor, also known as an electric motor or an electric motor, is an electrical device that converts electrical energy into mechanical energy and can then use the mechanical energy to generate kinetic energy to drive other devices.

[0003] When the motor molding mold is casting and molding, a large amount of heat will be generated, resulting in a slow molding speed of the motor accessories. Therefore, the mold needs to be cooled. However, the cooling devices installed in most molding molds are not effective. The Chinese patent with publication number CN215095431U discloses an injection mold that is easy to dissipate heat. Through the provision of a liquid inlet pipe and a cooling pipe, the cooling pipe is arranged on the outside of the bottom box. The coolant enters the cooling pipe through the liquid inlet pipe. The cooling pipe can reduce the temperature around the bottom box. At the same time, the coolant can circulate and flow, which can keep the temperature of the bottom box within a certain range. The mold injects cold water into the cooling pipe through the liquid inlet pipe, and then flows out from the liquid outlet pipe, achieving a certain cooling effect. However, when the cold water first flows into the liquid inlet pipe, the water temperature is low. In the process of entering the cooling pipe to dissipate heat to the mold, the cold water temperature gradually increases, resulting in uneven temperatures in the mold, affecting the molding quality of the accessories. Utility Model Content

[0004] The purpose of the utility model is to provide a motor accessory molding die that is easy to dissipate heat in view of the deficiencies in the prior art. In the process of cooling the upper convex die and the lower concave die by the cooling component, when the temperature of the hot water in the water outlet pipe is abnormal, the mercury absorbs and expands to drive the sliding piece to slide on the sliding rheostat, and the resistance of the sliding rheostat is adjusted to adjust the water flow rate of the cold water in the water inlet pipe, so as to achieve the effect of automatically adjusting the water flow rate and make the heat dissipation effect more uniform.

[0005] The technical solutions of the utility model are as follows:

[0006] A motor accessory forming mold that is easy to dissipate heat, includes an upper mold and a lower mold, an upper punch is fixedly arranged at the bottom of the upper mold, and a lower concave mold is fixedly arranged at the top of the lower mold, cooling components are arranged in the upper punch and the lower concave mold, water inlet pipes and water outlet pipes are respectively arranged on both sides of the upper punch and the lower concave mold, and monitoring components and adjustment components are respectively arranged at the water outlet pipe and water inlet pipe of the upper punch, the monitoring component includes a sliding rheostat, the cooling component is used to cool the upper punch and the lower concave mold, the monitoring component is used to adjust the resistance of the sliding rheostat according to the temperature of the hot water in the water outlet pipe, and the adjustment component is used to adjust the water flow rate of cold water in the water inlet pipe according to the resistance of the sliding rheostat.

[0007] Preferably, the cooling assembly includes a cooling pipe fixedly arranged in the upper punch and the lower die, a water inlet fixedly arranged at one end of the cooling pipe, and a water outlet fixedly arranged at the other end of the cooling pipe, and the water inlet and the water outlet are respectively connected to the water inlet pipe and the water outlet pipe.

[0008] Preferably, the monitoring assembly also includes a heat absorption tube fixedly arranged on the water outlet pipe at the upper punch, a piston slidably arranged in the heat absorption tube, and a piston rod fixedly arranged on the piston. The sliding rheostat is fixedly arranged on the upper mold, and the piston rod is fixedly connected to the sliding piece of the sliding rheostat. A spring is sleeved on the piston rod and the spring is fixedly connected between the piston and the heat absorption tube.

[0009] Preferably, the adjusting assembly includes an adjusting cylinder fixedly arranged on the upper mold, an electromagnetic plate fixedly arranged in the adjusting cylinder, a movable plate slidably arranged in the adjusting cylinder, and a spring fixedly connected between the movable plate and the adjusting cylinder, annular bags are arranged in the water inlet pipes at the upper punch and the lower die, and air pipes are connected between the annular bags, and a connecting pipe is connected between the air pipe and the adjusting cylinder.

[0010] As a preference, the sliding rheostat is electrically connected to the electromagnetic plate, and the electromagnetic plate is magnetically attracted to the moving plate.

[0011] Preferably, the top of the upper mold is also provided with an injection port, and the injection port is connected to the upper punch.

[0012] As a preference, mercury is arranged in the regulating cylinder.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model is provided with a monitoring component. When cold water flows from the water inlet pipe into the cooling pipe, the water temperature gradually increases in the process of absorbing heat. Therefore, the temperatures of the water inlet pipe and the water outlet pipe are different, resulting in different temperatures on both sides of the upper punch and the lower die. When the temperature at the water outlet pipe becomes higher and higher, and the temperature difference with the water inlet pipe becomes larger and larger, the temperature difference between the upper punch and the lower die is also large. Therefore, when the hot water in the water outlet pipe exceeds a certain temperature, the mercury absorbs heat and expands, pushing the piston and the piston rod to move, driving the sliding plate to move away from the heat absorption tube, reducing the resistance, and achieving the effect of automatically adjusting the resistance of the sliding rheostat according to the water temperature.

[0015] 2. The utility model is also provided with an adjustment component. When the water temperature is too high, the mercury drives the sliding piece to slide, so that the resistance of the sliding rheostat becomes smaller, the current of the electromagnetic plate becomes larger, the magnetic force becomes larger, and the magnetic force is greater than the elastic force of the spring. The electromagnetic plate pulls the moving plate closer, and the gas in the annular bag is drawn into the adjustment cylinder through the connecting pipe and the air pipe during the movement of the moving plate. At this time, the annular bag contracts, thereby increasing the space in the water inlet pipe allowing water to pass through, so that the flow rate of cold water becomes larger, and at the same time the flow of cold water is accelerated, and the hot water is quickly brought out of the upper convex mold and the lower concave mold for heat dissipation.

[0016] In summary, the utility model has the advantages of good heat dissipation effect and high speed, and is suitable for the field of motor molding technology. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present utility model are clearly and completely described below in conjunction with the accompanying drawings.

[0025] Embodiment 1

[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] like Figures 1 to 5 As shown, a motor accessory forming mold which is easy to dissipate heat includes an upper mold 1 and a lower mold 2. An upper punch 3 is fixedly arranged at the bottom of the upper mold 1, and a lower concave mold 4 is fixedly arranged at the top of the lower mold 2. Cooling components 5 are arranged in the upper punch 3 and the lower concave mold 4. Water inlet pipes 6 and water outlet pipes 7 are respectively arranged on both sides of the upper punch 3 and the lower concave mold 4. Monitoring components 8 and adjusting components 9 are respectively arranged at the water outlet pipe 7 and the water inlet pipe 6 of the upper punch 3. The monitoring component 8 includes a sliding rheostat 81. The cooling component 5 is used to cool the upper punch 3 and the lower concave mold 4. The monitoring component 8 is used to adjust the resistance of the sliding rheostat 81 according to the temperature of the hot water in the water outlet pipe 7. The adjusting component 9 is used to adjust the water flow rate of cold water in the water inlet pipe 6 according to the resistance of the sliding rheostat 81.

[0028] like Figures 1 to 3 As shown, the cooling assembly 5 includes a cooling pipe 51 fixedly arranged in the upper punch 3 and the lower die 4, a water inlet 52 fixedly arranged at one end of the cooling pipe 51, and a water outlet 53 fixedly arranged at the other end of the cooling pipe 51. The water inlet 52 and the water outlet 53 are respectively connected to the water inlet pipe 6 and the water outlet pipe 7. When in use, cold water enters the cooling pipe 51 through the water inlet 52 via the water inlet pipe 6. During the flow, the heat in the upper punch 3 and the lower die 4 is absorbed to achieve the heat dissipation effect. The heated water flows out from the water outlet 53 through the water outlet pipe 7, thereby solving the problem of slow molding speed of motor accessories caused by high temperature.

[0029] like Figures 2 to 4As shown, the monitoring assembly 8 also includes a heat absorbing tube 82 fixedly arranged on the water outlet pipe 7 at the upper punch 3, a piston 83 slidably arranged in the heat absorbing tube 82, and a piston rod 84 fixedly arranged on the piston 83. The sliding rheostat 81 is fixedly arranged on the upper mold 1, and the piston rod 84 is fixedly connected to the sliding piece of the sliding rheostat 81. A spring is sleeved on the piston rod 84 and the spring is fixedly connected between the piston 83 and the heat absorbing tube 82. Among them, cold water enters the cooling tube 51 from the water inlet pipe 6 and absorbs heat during the flow, so that the water temperature gradually increases. Therefore, the temperatures of the water inlet pipe 6 and the water outlet pipe 7 are different, resulting in different temperatures on both sides of the upper punch 3 and the lower concave mold 4. When the temperature at the water outlet pipe 7 becomes higher and higher, the temperature difference with the water inlet pipe 6 becomes higher and higher. When the temperature is large, the temperature difference between the upper punch 3 and the lower die 4 is also large. In addition, the sliding rheostat 81 is electrically connected to the external switch. After the switch is turned on, the sliding rheostat 81 is energized, and the initial position of the slider is in the middle. When the slider slides away from the heat absorption tube 82, the resistance becomes smaller, the current of the electromagnetic plate 92 becomes larger, and the magnetic force becomes larger. When sliding toward the heat absorption tube 82, the resistance becomes larger, the current of the electromagnetic plate 92 becomes smaller, and the magnetic attraction becomes smaller. When in use, when the hot water in the water outlet pipe 6 exceeds a certain temperature, the mercury absorbs heat and expands, pushing the piston 83 and the piston rod 84 to move, driving the slider to move away from the heat absorption tube 82, reducing the resistance, and achieving the effect of automatically adjusting the resistance of the sliding rheostat 81 according to the water temperature.

[0030] like Figure 4 and Figure 5 As shown, the adjusting assembly 9 includes an adjusting cylinder 91 fixedly arranged on the upper mold 1, an electromagnetic plate 92 fixedly arranged in the adjusting cylinder 91, a moving plate 93 slidably arranged in the adjusting cylinder 91, and a spring 94 fixedly connected between the moving plate 93 and the adjusting cylinder 91. Annular capsules 95 are arranged in the water inlet pipes 6 at the upper punch 3 and the lower die 4, and air pipes 96 are connected between the annular capsules 95. A connecting pipe 97 is connected between the air pipe 96 and the adjusting cylinder 91, wherein the connecting pipe 97 and the air pipe 96 are both hoses. The annular capsule 95 is initially bulged. When the water temperature is too high, the mercury drives the slider to slide, making the resistance of the sliding rheostat smaller, the current of the electromagnetic plate 92 larger, the magnetic force larger and greater than the elastic force of the spring 94, then the electromagnetic plate 92 pulls the moving plate 93 closer, and the moving plate 93 moves. During the movement of the annular bag 95, the gas is drawn into the regulating cylinder 91 through the connecting pipe 97 and the air pipe 96. At this time, the annular bag 95 contracts, thereby increasing the space in the water inlet pipe 6 allowing water to pass through, increasing the flow rate of cold water, and accelerating the flow of cold water, quickly bringing the hot water out of the upper punch 3 and the lower die 4 for heat dissipation.

[0031] like Figure 5 As shown, the sliding resistor 81 is electrically connected to the electromagnetic plate 92 , and the electromagnetic plate 92 and the moving plate 93 are magnetically attracted to each other.

[0032] like Figure 2 As shown, an injection port 10 is also provided on the top of the upper mold 1 , and the injection port 10 is connected to the upper punch 3 .

[0033] like Figure 5 As shown, mercury is arranged in the adjusting cylinder 91, and the resistance of the sliding rheostat 81 is adjusted by the mercury absorbing heat and expanding.

[0034] Working process

[0035] When the hot water in the water outlet pipe 6 exceeds a certain temperature, the mercury absorbs heat and expands, pushing the piston 83 and the piston rod 84 to move, driving the slide to move away from the heat absorption tube 82, reducing the resistance, and the magnetic force of the electromagnetic plate 92 is greater than the elastic force of the spring 94. The electromagnetic plate 92 pulls the moving plate 93 closer. During the movement of the moving plate 93, the gas in the annular bag 95 is drawn into the regulating cylinder 91 through the connecting pipe 97 and the air pipe 96. At this time, the annular bag 95 contracts, thereby increasing the space in the water inlet pipe 6 allowing water to pass through, increasing the flow rate of cold water, and accelerating the flow of cold water to quickly bring the hot water out of the upper punch 3 and the lower die 4 for heat dissipation.
