An air cylinder 19 is fixedly mounted on the outer wall of the inner cylinder 16. A sliding rod 23 is arranged on the inner wall of the air cylinder 19. A pressure pump 18 is fixedly mounted on the outer wall of the air cylinder 19. An air delivery pipe 20 and a connecting pipe 36 are respectively passed through the outer wall of the air cylinder 19. A heat preservation groove 24 is opened on the outer wall of the inner cylinder 16. A fixing ring 21 is fixedly mounted on the inner wall of the heat preservation groove 24. The outer wall of the fixing ring 21 is rotatably connected to a rotating shaft 2 2. The outer wall of the bevel gear 7 is rotatably connected to the outer cylinder 30, the outer wall of the outer cylinder 30 is slidably connected to the sliding ring 33, the outer wall of the sliding ring 33 is fixedly equipped with a scale 28, the outer wall of the base 1 is respectively fixedly equipped with a controller 25, a rangefinder 29 and an infrared transmitter 27, the outer wall of the sliding ring 33 is provided with a reset spring 35, the outer wall of the reset spring 35 is provided with an electromagnet 34, the outer wall of the electromagnet 34 is fixedly equipped with an arc plate 32, and the outer wall of the sliding ring 33 is provided with a telescopic rod 31.

[0028] In the above structure, by setting the base 1, motor 2, rotating cylinder 3, connecting ring 4, injection tube 5, hopper 6, fixed ring 21, rotating shaft 22, slide rod 23, and heat preservation tank 24 structure, the user can rotate the extrusion rod 14 by the operation of the motor 2 during the operation of the device. Since the rotating member 12 is fixedly connected to the extrusion rod 14, the rotating member 12 drives the rotating cylinder 3 to rotate synchronously, so that the user can use the rotation of the rotating cylinder 3 to move the slide ring 33 during the operation of the device, so as to ensure that the scale 28 of the device moves when the silicone is extruded, and the bevel gear 7 rotates at the same time, and the distance meter 29 and the infrared sensor 26 are counted. The number of overlaps and the use of the rangefinder 29 to calculate the moving distance of the scale 28 make it convenient for the user to calculate the amount of silicone extruded by the extrusion rod 14. At the same time, the movement of the sliding ring 33 can allow the piston on the sliding rod 23 to extrude the high-pressure air inside the air cylinder 19, so that the high-pressure air flows at a high speed and blows the rotating shaft 22, so that the high-speed flowing air and the frosting plate on the rotating shaft 22 generate friction, thereby achieving the effect of heat generation by friction between air flow and objects, forming a thermal barrier, reducing the speed of heat loss inside the rotating cylinder 3 during operation, and thus facilitating the user to perform injection operations more accurately, and can also reduce heat loss, thereby improving the energy utilization rate of the device.

[0029] In a preferred embodiment: the number of air cylinders 19 is three, the number of connecting pipes 36 is two, and the three air cylinders 19 are connected by two connecting pipes 36, the interior of the insulation tank 24 is connected to the interior of the air cylinder 19 through the sliding rod 23, a one-way valve is provided on the inner wall of one end of the air supply pipe 20 close to the air cylinder 19, a piston is fixedly assembled on one end of the sliding rod 23 close to the air cylinder 19, and the outer wall of the piston is slidably connected to the inner wall of the air cylinder 19.

[0030] In the above structure, the piston structure is set up so that the slide rod 23 can drive the piston to move during the movement, so that the air inside the air cylinder 19 can be squeezed out through the air supply pipe 20, thereby reducing the storage space of the high-pressure air and achieving the effect of accelerating the flow rate of the high-pressure air, thereby ensuring that the frosting plate on the rotating shaft 22 is impacted and rubbed with the high-pressure air to generate heat, reducing the heat loss rate, and ensuring that the probability of condensation of silicone during the transportation process is reduced.

[0031] In a preferred embodiment, the position of the infrared sensor 26 corresponds to the position of the infrared transmitter 27 , and the position of the rangefinder 29 corresponds to the position of the scale 28 , and the rangefinder 29 is electrically connected to the controller 25 .

[0032] In the above structure, by setting the scale 28 and the distance meter 29 structure, during the operation of the device, the distance meter 29 is used to calculate the moving distance of the scale 28, so as to cooperate with the controller 25 to output the calculation result on the control panel, so as to facilitate the user to know the amount of silica gel transported by the device, thereby ensuring the accuracy of the user's material transportation. At the same time, the statistics of the number of rotations of the bevel gear 7 by the infrared sensor 26 and the infrared transmitter 27 can be used to verify whether the transported volume corresponds to the current volume, thereby improving the calculation accuracy of the device for the amount of silica gel.

[0033] In a preferred embodiment: the outer wall of the arc plate 32 is threadedly connected to the inner wall of the rotating cylinder 3, the telescopic end of the telescopic rod 31 is fixedly assembled with the outer wall of the arc plate 32, and a strong magnet is provided on the outer wall of the sliding ring 33, and the strong magnet and the electromagnet 34 are attracted to each other by opposite charges.

[0034] In the above structure, by setting up the strong magnet and electromagnet 34 structure, when performing the extrusion operation, the user can make the arc plate 32 threadedly connected with the inner wall of the outer cylinder 30 by turning off the power of the electromagnet 34, so that when the rotating cylinder 3 rotates, the high-pressure air will be transferred to make the slide rod 23 move toward the air cylinder 19. The reduction in air pressure and the threaded connection structure will make the slide ring 33 slide along the outer wall of the outer cylinder 30, thereby making the push scale 28 move and the bevel gear 7 rotate, thereby achieving the effect of accurately counting the amount of silicone delivered.

[0035] In a preferred embodiment: the number of fixed rings 21 is several, and the several fixed rings 21 are evenly distributed along the inner wall of the insulation tank 24, the number of transmission wheels 9 is two, and the two transmission wheels 9 are connected to each other through a transmission belt 10, the outer wall of the rotating rod 11 is fixedly equipped with a cleaning plate, and the outer wall of the cleaning plate is rotatably connected to the inner wall of the hopper 6.

[0036] In the above structure, through the cleaning plate and the transmission wheel 9 structure, the rotation of the bevel gear 7 can not only achieve the effect of synchronously counting the amount of silicone delivered by the extrusion rod 14, but also drive the bevel gear 2 15 to rotate when the bevel gear 7 rotates, so that the rotating rod 1 8 rotates and cooperates with the transmission of the transmission wheel 9 and the transmission belt 10 to drive the rotating rod 2 11 to rotate, so that the cleaning plate scrapes the inside of the hopper 6 and stirs the silicone material, thereby ensuring that the silicone material will not stick during the transportation process, thereby improving the transportation effect of the device on the silicone material.

[0037] In a preferred embodiment, the interior of the hopper 6 is communicated with the interiors of the rotating cylinder 3 and the connecting ring 4 through the injection tube 5 , and the interior of the rotating cylinder 3 is communicated with the interior of the mold through the extrusion head 13 .

[0038] In the above structure, by providing the rotating cylinder 3 and the extrusion head 13 structure, the material is pushed into the mold by the rotation of the extrusion rod 14, thereby achieving the effect of automatic injection, and making it easier for users to operate the injection molding device.

[0039] In a preferred embodiment: the interior of the air cylinder 19 is filled with high-pressure air, and a solenoid valve is provided at the connection between the connecting pipe 36 and the air cylinder 19, an electric pressure relief valve is provided on the outer wall of the outer cylinder 30, and the interlayer between the outer cylinder 30 and the inner cylinder 16 is connected to the outside through the electric pressure relief valve.

[0040] In the above structure, through the solenoid valve and electric pressure relief valve structure, when the high-pressure air does not need to be transferred, the closing of the solenoid valve can ensure that the high-pressure air is always in the air cylinder 19 to avoid leakage, thereby improving the sealing of the device. When the high-pressure air is transferred and generates friction and heat with the rotating shaft 22, in order to ensure the pressure balance of the device, the electric pressure relief valve will directly discharge the unheated high-pressure air that is subsequently discharged, so as to avoid the explosion of the device caused by excessive air pressure during subsequent operations. At the same time, it can also avoid the mixing of heated high-pressure air and unheated high-pressure air to cause high-level heat energy to be transferred to low-level heat energy, further reducing the rate of heat energy loss, thereby ensuring that the subsequent use of the device will not be affected.

[0041] In a preferred embodiment: a control panel is disposed on the outer wall of the base 1 , and the control panel is electrically connected to the controller 25 and the infrared emitter 27 , respectively.

[0042] In the above structure, through the control panel and controller 25 structure, the controller 25 and the infrared transmitter 27 can directly display the calculation results on the control panel, so as to facilitate the user to count the final data, thereby improving the practicality of the device.

[0043] In a preferred embodiment: the outer wall of the rotating shaft 22 is fixedly equipped with a grinding plate, the number of the grinding plates is three, and the three grinding plates are evenly distributed along the outer wall of the rotating shaft 22, the inner wall of the rotating member 12 is fixedly equipped with a connecting rod, and the end of the connecting rod is fixedly equipped with the end of the rotating cylinder 3 away from the rotating member 12.

[0044] In the above structure, through the setting of the rotating shaft 22 and the frosted plate structure, when the high-pressure air is transferred to the insulation tank 24, the high-speed flowing high-pressure air is used to make the high-pressure air impact the frosted plate, thereby causing friction between the frosted plate and the high-pressure air. The roughness of the frosted plate is relatively large, so the effect of generating heat by friction between the object and the air can be achieved, thereby forming a thermal protection layer to reduce the rate of heat loss.

[0045] Working principle: First, after the user assembles the device, he can pour the material into the hopper 6. The heated silicone will accumulate in the hopper 6. At this time, the user can use the operation of the motor 2 to make the extrusion rod 14 drive the bevel gear 7 to rotate, so that the rotating rod 11 and the cleaning plate can scrape and stir the material inside the hopper 6 at the same time to avoid material condensation. At this time, since the electromagnet 34 and the strong magnet are in a state of opposite attraction, the sliding ring 33 of the extrusion rod 14 is always stationary when it rotates. When the extrusion rod 14 starts to extrude, the user can disconnect the power of the electromagnet 34 to make the arc plate 32 and the inner wall of the rotating cylinder 3 threadedly connected, so that the scale 28 of the extrusion rod 14 moves during the extrusion operation to calculate the amount of silicone extruded by the extrusion rod 14, and at the same time, the rotation of the bevel gear 7 drives the positioning ring 1 7 rotates, so that the infrared sensor 26 overlaps with the positioning circle 17 once every time the positioning circle 17 rotates one circle, and the amount of silicone delivered by the extrusion rod 14 on the basis of the unchanged diameter of the extrusion rod 14 is synchronously counted, thereby ensuring that the user can accurately grasp the delivery amount of silicone when the device is in operation, thereby improving the practicality of the device, and when the sliding ring 33 moves, it will also drive the sliding rod 23 to move, so that the high-pressure air in the air cylinder 19 is transferred to the insulation tank 24 through the air supply pipe 20, and the squeezed high-pressure air will accelerate the flow rate. The specific small-diameter air outlet can make the high-pressure air blow to the rotating shaft 22 at the flow rate of pneumatic heating, so that the frosting plate and the high-pressure air produce friction to form a thermal barrier, thereby achieving the effect of reducing the heat flow rate, and the cleaning plate still performs scraping and stirring operations simultaneously, thereby improving the energy utilization rate of the device.
