Description

Technical Field

[0001] The invention relates to the technical field of forming dies, in particular to a forming die with a self-cooling function. Background Art

[0002] The compression molding mold is to add the plastic raw material directly into the open mold cavity, and then close the mold. Under the action of heat and pressure, the plastic becomes fluid and fills the cavity.

[0003] Citing a Chinese invention, patent number CN108262919B, discloses an injection mold for automotive lamps with a self-cooling function, comprising a mold body with an intelligently controlled cooling mechanism on the outer surface of the mold body. The invention provides a convenient device for effectively raising and lowering the poured material for cooling, facilitating uniform and rapid cooling, and ensuring uniform molding.

[0004] During the molding process of the mold, the temperature of the material is high, which in turn drives the temperature of the mold to rise. The increase in mold temperature will not only prolong the cooling time of the material, but also the high temperature of the mold will shorten the service life of the mold. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a forming mold with a self-cooling function to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a forming mold with a self-cooling function, comprising a workbench, a first mold fixedly connected to the top of the workbench, a slide rail also fixedly connected to the top of the workbench, an electric slider slidably connected to the outer wall of the slide rail, a second mold fixedly connected to the outer wall of the electric slider, and an airflow mechanism fixedly connected to the outer wall of the second mold;

[0007] The airflow mechanism comprises:

[0008] a bracket, one end of which is fixedly connected to the outer wall of the slide rail;

[0009] A zigzag tube, the other end of the bracket is fixedly connected to the outer wall of the zigzag tube, an air flow port is opened on the top of the zigzag tube, and the bottom of the zigzag tube is fixedly connected to the top of the second mold. When the second mold rises again, the second mold squeezes the gas in the zigzag tube, and the air flow blows out from the inlet, which drives the moisture in the sponge board to be discharged. The air flow carries the moisture and blows onto the first mold, accelerating the reduction of the temperature of the first mold. Through the transportation of water flow, the air flow drives the movement of water flow during the flow process, thereby producing an effect of accelerated heat dissipation.

[0010] Preferably, the inner top of the zigzag tube is fixedly connected to a first spring, and the top of the first spring is fixedly connected to a circular plate, utilizing the fact that the zigzag tube will shrink during the rising process of the second mold, and the second mold squeezes the gas in the zigzag tube, and the gas in the zigzag tube is discharged from the inlet, and the air flow blows onto the first mold below the second mold. The flow of the air flow will accelerate the reduction of the temperature of the first mold, and the flow of the air flow will accelerate the flow of the air flow near the first mold and the second mold, thereby accelerating the reduction of the temperature of the first mold and the second mold.

[0011] Preferably, an air bag is fixedly connected to the top of the circular plate, and the air bag is in movable contact with the inner top of the zigzag tube.

[0012] Preferably, an inner wall of the second mold is fixedly connected with an inclined plate, an outer wall of the inclined plate is provided with a hole, and a sponge plate is fixedly connected to the outer wall of the inclined plate at the position of the hole.

[0013] Preferably, a water flow mechanism is fixedly connected to the bottom of the second mold, and the water flow mechanism includes an inlet, which is opened at the bottom of the second mold.

[0014] Preferably, a pressure rod is fixedly connected to the bottom of the second mold at the position of the feeding inlet, and a water pump is fixedly connected to the left side of the first mold.

[0015] Preferably, one end of a water pipe is fixedly connected to the left side of the water pump, and the other end of the water pipe is fixedly connected to a water tank. The water tank is fixedly connected to the top of the workbench. The water pump draws water from the water tank and then discharges it into the water flow channel. Water is set inside the first mold, so the water setting will quickly cool down the temperature of the first mold. The water setting produces an effect of accelerating the rapid reduction of the temperature of the first mold, avoiding the excessive temperature affecting the service life of the mold. A certain amount of water is stored in the water tank in advance, and the water pump is plugged into the water tank through a water pipe. The water pump draws water from the water tank and then discharges it into the water flow channel. Water is set inside the first mold, so the water setting will quickly cool down the temperature of the first mold. The rubber block on the movable rod is set in the water flow channel, and the setting of the rubber block will block the water flow The channel prevents water from discharging. When the second mold cooperates with the first mold to extrude the material, the movable rod is inserted into the feed port. At this time, the pressure rod and the movable rod squeeze each other, and the movable rod drives the rubber block down during the squeezing process. As shown in the figure, when the rubber block drops into the water flow channel, the water entering the water flow channel will be discharged to the second mold through the water flow channel at the top of the first mold. The sponge plate absorbs the water discharged into the second mold, and then the sponge plate is set obliquely, so the water will be deposited above the inclined plate. The existence of water flow in the second mold will lower the temperature of the second mold, and then when the second mold rises again, the second mold squeezes the gas in the tortuous tube, and the air flow will drive the water in the sponge plate to be discharged when it blows out from the feed port, and the air flow carries the water to the first mold.

[0016] Preferably, a water flow channel is opened inside the first mold, and the second mold cooperates with the first mold to extrude the material, so the second mold will move during the cyclic extrusion of the material. The movement of the second mold generates air flow, which accelerates the heat dissipation of the first mold and the second mold. In addition, the pressure rod and the movable rod squeeze each other, and the water in the water flow channel will be discharged into the second mold through the water flow channel at the top of the first mold. During the extrusion process of the first mold and the second mold, the water in the first mold will be transported to the second mold, which produces the effect of water dissipating heat to the second mold. The sponge plate absorbs the water discharged into the second mold, and then the sponge plate is arranged obliquely, so that the water will be deposited above the inclined plate. The presence of water in the second mold will reduce the temperature of the second mold, and the accumulation of water has the effect of continuously dissipating heat to the second mold. The top of the first mold is fixedly connected to a second spring at a position in the water flow channel, and the outer wall of the second spring is fixedly connected to a movable rod. The movable rod is inserted into the water flow channel, the movable rod is inserted into the feed port and is in movable contact with the pressure rod, and the bottom of the movable rod is fixedly connected to a rubber block.

[0017] The present invention provides a forming mold with a self-cooling function. It has the following beneficial effects:

[0018] 1. The forming mold with a self-cooling function utilizes the second mold to cooperate with the first mold to extrude the material, so the second mold will move during the cyclic extrusion of the material. The movement of the second mold generates air flow, which accelerates the heat dissipation of the first mold and the second mold. Moreover, the pressure rod and the movable rod squeeze each other, and the water in the water flow channel will be discharged into the second mold through the water flow channel at the top of the first mold. During the extrusion process of the first mold and the second mold, the water in the first mold will be transported to the second mold, resulting in the effect of water dissipating heat to the second mold. The sponge plate absorbs the water discharged into the second mold, and then the sponge plate is set obliquely, so the water will be deposited above the inclined plate. The presence of water flow in the second mold will reduce the temperature of the second mold, and the accumulation of water flow has the effect of continuously dissipating heat to the second mold.

[0019] 2. The forming mold with a self-cooling function utilizes the contraction of the zigzag tube during the rising process of the second mold. The second mold squeezes the gas in the zigzag tube, and the gas in the zigzag tube is discharged from the inlet. The air flow blows onto the first mold below the second mold. The flow of the air flow accelerates the reduction of the temperature of the first mold, and the flow of the air flow accelerates the flow of the air flow near the first and second molds, thereby accelerating the reduction of the temperature of the first and second molds.

[0020] 3. The forming mold with self-cooling function draws water from the water tank through a water pump and then discharges it into the water flow channel. Water is set inside the first mold, so the setting of water can quickly cool down the temperature of the first mold. The setting of water accelerates the rapid reduction of the temperature of the first mold, avoiding excessive temperature affecting the service life of the mold.

[0021] 4. This forming mold with a self-cooling function squeezes the gas in the zigzag tube when the second mold rises again. When the air flow is blown out from the inlet, it drives the moisture in the sponge board to be discharged. The air flow carries the moisture to the first mold, accelerating the temperature reduction of the first mold. Through the transportation of water flow, the air flow drives the movement of water flow during the flow process, resulting in the effect of accelerated heat dissipation.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] 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, but are not to be construed as limiting the present invention. Example 1

[0032] See also Figure 1-4 The present invention provides a technical solution: a forming mold with a self-cooling function, comprising a workbench 1, a first mold 2 is fixedly connected to the top of the workbench 1, a slide rail 5 is also fixedly connected to the top of the workbench 1, an electric slider 4 is slidably connected to the outer wall of the slide rail 5, a second mold 3 is fixedly connected to the outer wall of the electric slider 4, and an airflow mechanism 6 is fixedly connected to the outer wall of the second mold 3;

[0033] The airflow mechanism 6 comprises:

[0034] A bracket 61, one end of which is fixedly connected to the outer wall of the slide rail 5;

[0035] The zigzag tube 63 and the other end of the bracket 61 are fixedly connected to the outer wall of the zigzag tube 63. An air flow port 62 is provided at the top of the zigzag tube 63. The bottom of the zigzag tube 63 is fixedly connected to the top of the second mold 3. When the second mold 3 rises again, the second mold 3 squeezes the gas in the zigzag tube 63. When the air flow is blown out from the inlet 92, it will drive the moisture in the sponge board 7 to be discharged. The air flow carries the moisture and blows onto the first mold 2, accelerating the reduction of the temperature of the first mold 2. Through the transportation of water flow, the air flow drives the movement of water flow during the flow process, thereby producing the effect of accelerated heat dissipation.

[0036] The inner top of the zigzag tube 63 is fixedly connected to a first spring 66, which utilizes the fact that the zigzag tube 63 will shrink during the rising process of the second mold 3, and the second mold 3 squeezes the gas in the zigzag tube 63. The gas in the zigzag tube 63 is discharged from the inlet 92, and the air flow blows onto the first mold 2 below the second mold 3. The flow of the air flow will accelerate the temperature reduction of the first mold 2, and the flow of the air flow will accelerate the flow of the air flow near the first mold 2 and the second mold 3, thereby accelerating the temperature reduction of the first mold 2 and the second mold 3. The top of the first spring 66 is fixedly connected to a circular plate 65.

[0037] The top of the circular plate 65 is fixedly connected to an air bag 64 , and the air bag 64 is in movable contact with the inner top of the zigzag tube 63 .

[0038] During use, the workbench 1 is installed in the required position, the first mold 2 is placed on the workbench 1, and the electric slider 4 is movable on the slide rail 5. The electric slider 4 drives the second mold 3 to move up and down during the movement, and the second mold 3 descends onto the first mold 2. The second mold 3 and the first mold 2 extrude and mold the material. The zigzag tube 63 will shrink during the rising process of the second mold 3, and the second mold 3 squeezes the gas in the zigzag tube 63. When the gas in the zigzag tube 63 is squeezed, the circular plate 65 and the airbag 64 are squeezed by the gas to fit the inner top of the zigzag tube 63, preventing the gas from being discharged from the air flow port 62. At this time, the gas in the zigzag tube 63 is discharged from the inlet 92, and the air flow blows onto the first mold 2 below the second mold 3. The flow of air will accelerate the reduction of the temperature of the first mold 2. When the second mold 3 descends, the zigzag tube 63 is stretched and lengthened. At this time, the external gas will push up the airbag 64, and then the air flow enters the zigzag tube 63 from the air flow port 62. The setting of the first spring 66 then enables the airbag 64 to move. Example 2

[0039] See also Figure 1-7 Based on the first embodiment, the present invention provides a technical solution:

[0040] An inclined plate 8 is fixedly connected to the inner wall of the second mold 3 , a hole is opened on the outer wall of the inclined plate 8 , and a sponge plate 7 is fixedly connected to the outer wall of the inclined plate 8 at the position of the hole.

[0041] A water flow mechanism 9 is fixedly connected to the bottom of the second mold 3 . The water flow mechanism 9 includes an inlet 92 . The inlet 92 is opened at the bottom of the second mold 3 .

[0042] The bottom of the second mold 3 is located at the position of the feed inlet 92 and is fixedly connected to a pressure rod 91. The second mold 3 cooperates with the first mold 2 to extrude the material, so the second mold 3 will move during the cyclic extrusion of the material. The movement of the second mold 3 generates air flow, which accelerates the heat dissipation of the first mold 2 and the second mold 3. The pressure rod 91 and the movable rod 97 squeeze each other, and the water in the water flow channel 96 will be discharged to the second mold 3 through the water flow channel 96 at the top of the first mold 2. During the extrusion process of the first mold 2 and the second mold 3, the water in the first mold 2 will be transported to the second mold 3, resulting in the effect of water dissipating heat to the second mold 3. The sponge plate 7 absorbs the water discharged into the second mold 3, and then the sponge plate 7 is set obliquely, so the water will be deposited above the inclined plate 8. The presence of water flow in the second mold 3 will reduce the temperature of the second mold 3, and the accumulation of water flow has the effect of continuously dissipating heat to the second mold 3. A water pump 95 is fixedly connected to the left side of the first mold 2.

[0043] One end of a water pipe 94 is fixedly connected to the left side of the water pump 95, and the other end of the water pipe 94 is fixedly connected to a water tank 93. The water tank 93 is fixedly connected to the top of the workbench 1. The water pump 95 extracts water from the water tank 93 and then discharges it into the water flow channel 96. Water is set inside the first mold 2, so the setting of water will quickly cool down the temperature of the first mold 2. The setting of water produces an effect of accelerating the rapid reduction of the temperature of the first mold 2, thereby avoiding excessive temperature affecting the service life of the mold.

[0044] A water flow channel 96 is opened inside the first mold 2, and a second spring 98 is fixedly connected to the top of the first mold 2 at the position of the water flow channel 96. The outer wall of the second spring 98 is fixedly connected to a movable rod 97, which is inserted into the water flow channel 96. The movable rod 97 is inserted into the feed port 92 and is in movable contact with the pressure rod 91. The bottom of the movable rod 97 is fixedly connected to a rubber block 99.

[0045] During use, a certain amount of water is stored in the water tank 93 in advance, and the water pump 95 is plugged into the water tank 93 through the water pipe 94. The water pump 95 extracts the water in the water tank 93 and then discharges it into the water flow channel 96. Water is set inside the first mold 2, so the setting of the water will quickly cool down the temperature of the first mold 2. The rubber block 99 on the movable rod 97 is set in the water flow channel 96. The setting of the rubber block 99 will block the water flow channel 96 and prevent the water from being discharged. When the second mold 3 cooperates with the first mold 2 to extrude the material, the movable rod 97 is inserted into the feed port 92. At this time, the pressure rod 91 and the movable rod 97 squeeze each other, and the movable rod 97 drives the rubber block 99 to drop during the squeezing process. Figure 7 As shown, when the rubber block 99 descends into the water flow channel 96, the water entering the water flow channel 96 will be discharged into the second mold 3 through the water flow channel 96 at the top of the first mold 2, and the sponge plate 7 absorbs the water discharged into the second mold 3. Then, the sponge plate 7 is set obliquely, so the water will be deposited above the inclined plate 8. The existence of water flow in the second mold 3 will reduce the temperature of the second mold 3. Then, when the second mold 3 rises again, the second mold 3 squeezes the gas in the zigzag tube 63. When the air flow is blown out from the inlet 92, it will drive the water in the sponge plate 7 to be discharged. The air flow carries the water and blows it onto the first mold 2, accelerating the reduction of the temperature of the first mold 2.
