Implementation

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] like Figure 1 , Figure 2 , Figure 7As shown, a rubber solid tire injection device comprises a static mold 2, a cleaning component 1 is fixedly connected to the bottom of the static mold 2, a mobile component 3 is fixedly connected to the top four corners of the cleaning component 1, an injection component 4 is fixedly installed on the top of the mobile component 3, a positioning groove 21 is opened on the top of the static mold 2, and a protrusion 22 is fixedly installed on the inner wall of the static mold 2 in a circular array, and a heat conduction pipe 23 is fixedly connected to the surface of the protrusion 22; the cleaning component 1 comprises a base 11, the top of the base 11 is fixedly connected to the bottom of the static mold 2, the top four corners of the base 11 are fixedly connected to the bottom of the mobile component 3, the bottom left side of the base 11 is fixedly connected to a limiting frame 12, and the bottom right side of the base 11 is fixedly connected to a rotating The rotating frame 13; the moving component 3 includes supporting legs 31, the bottom surfaces of the four supporting legs 31 are fixedly connected to the top of the base 11, the top of the four supporting legs 31 is fixedly connected to a top plate 32, the top left and right sides of the top of the top plate 32 are fixedly connected to side plates 33, the opposite surfaces of the two side plates 33 are rotatably connected to a transmission shaft 34, and a motor 38 is fixedly installed on the right side of one group of the two side plates 33; the injection component 4 includes a pump 41, the bottom surface of the pump 41 is fixedly connected to the top surface of the top plate 32, the output end of the pump 41 is fixedly connected to a connecting pipe 42, the outer surface of the connecting pipe 42 is fixedly plugged into the inside of the top plate 32, and the bottom of the connecting pipe 42 is fixedly plugged with a spring hose 43.

[0022] Before the injection of the fluid solid tire rubber raw material, the interior of the static mold 2 will be cleaned. After the cleaning is completed, the space on the top of the static mold 2 is vacated and the ball screw 37 and the screw connector 45 drive the dynamic mold 46 to seal the top surface of the static mold 2, forming a closed injection space between the two. After that, the fluid solid tire rubber raw material is injected into the static mold 2. The convex block 22 in the static mold 2 allows the surface of the solid tire to have a stronger grip after molding. The heat pipe 23 on its surface can conduct heat faster after the fluid solid tire rubber raw material is injected, thereby accelerating the molding process of the solid tire.

[0023] like Figure 2 , Figure 3 As shown, a motor 14 is fixedly installed on the front of the rotating frame 13, and a gear 15 is rotatably connected to the inner side of the rotating frame 13, and one end of the gear 15 is fixedly connected to the output end of the motor 14; a toothed plate 16 is meshed on the surface of the gear 15, and the bottom surface of the left end of the toothed plate 16 is slidably connected to the inner top surface of the limiting frame 12, and the left end top surface of the toothed plate 16 is fixedly connected to a connecting frame 17; a toothed plate 16 is meshed on the surface of the gear 15, and the bottom surface of the left end of the toothed plate 16 is slidably connected to the inner top surface of the limiting frame 12, and the left end top surface of the toothed plate 16 is fixedly connected to the connecting frame 17; a wind disk 19 is fixedly connected to the bottom end of the connecting frame 17, and the wind disk 19 is a hollow disk-shaped object, and a plurality of groups of dust cleaning nozzles are distributed on the bottom surface of the wind disk 19 in a circular array, and a fan 18 with an output end penetrating the top surface of the wind disk 19 is fixedly installed on the top of the wind disk 19.

[0024] When cleaning, the motor 14 drives the gear 15 to rotate, so that the tooth plate 16 slides on the limit frame 12, so that the connecting frame 17 drives the wind disc 19 to clean the inside of the static mold 2. After the cleaning is completed, the motor 14 is reversed to drive the wind disc 19 to reset, so as to continue the subsequent tire injection process.

[0025] like Figure 1-7 As shown, the output end of motor 2 38 is fixedly connected to one end of the transmission shaft 34, the surface of the transmission shaft 34 is fixedly connected to a bevel gear 1 35, and the surfaces of the two bevel gears 1 35 are meshed with bevel gears 2 36; the bottoms of the two bevel gears 2 36 are fixedly connected to ball screws 37, the surfaces of the two ball screws 37 are connected to the interior of the top plate 32 for rotation, and the bottom ends of the two ball screws 37 are connected to the top surface of the base 11 for rotation.

[0026] The two sets of bevel gears 1 35 and bevel gears 2 36 cooperate to ensure that the two sets of ball screws 37 can rotate synchronously when the transmission shaft 34 rotates, so as to ensure that the descent of the movable mold 46 can remain horizontal without tilting to one side, so that the injection cavity of the flow-like solid tire rubber raw material can be more compact and no leakage will occur during the injection process.

[0027] like Figure 5 , Figure 6 As shown, a shunt tube 44 is fixedly connected to the bottom of the spring hose 43, and two flow tubes for transmitting liquid are arranged at the bottom of the shunt tube 44, and a movable mold 46 is fixedly connected to the outer surface of the flow tube at the bottom of the shunt tube 44; screw connectors 45 are fixedly connected to both sides of the movable mold 46, and the inner walls of the two screw connectors 45 are respectively threadedly connected to the outer surface of the ball screw 37, and a positioning plate 47 is fixedly connected to the bottom of the movable mold 46, and the outer surface of the positioning plate 47 is movably connected to the inner wall of the positioning groove 21; an injection plate 48 is fixedly connected to the bottom of the movable mold 46, and the top surfaces of the two injection plates 48 are respectively fixedly connected to the flow tubes at the bottom of the shunt tube 44, and a liquid injection hole 49 is provided on the bottom surface of the injection plate 48.

[0028] The spring hose 43 and the shunt pipe 44 provide a channel for the injection of the fluid solid tire rubber raw material. The spring hose 43 ensures that the movable mold 46 has enough displacement space for displacement during the preparation work before injection. The shunt pipe 44 allows the fluid solid tire rubber raw material to be injected into the molding cavity of the solid tire at the same flow rate and flow rate during the injection process.

[0029] The working principle of the present invention is as follows: the motor 14 is started to drive the gear 15 to rotate, and the toothed plate 16 drives the wind disc 19 on the connecting frame 17 to move horizontally along the direction of rotation until the wind disc 19 is above the static mold 2, and the fan 18 is started to spray air from the nozzle at the bottom of the wind disc 19, so as to clean the inside of the static mold 2. After the cleaning is completed, the motor 14 is reversed to drive the wind disc 19 to reset, and then the motor 2 38 is started to make the two sets of bevel gears 1 35 on the transmission shaft 34 rotate, so that the two sets of ball screws 37 are synchronously and uniformly rotated. The moving mold 46 moves downward, and the spring hose 43 is pulled and stretched during the displacement until the positioning plate 47 is inserted into the positioning groove 21. The flow-like solid tire rubber raw material is extracted by the pump 41 and transported to the diverter pipe 44 through the spring hose 43. The diverter pipe 44 diverts the incoming flow-like solid tire rubber raw material and injects it into the solid tire injection space between the static mold 2 and the moving mold 46 from the injection hole 49 at the bottom of the injection plate 48.

[0030] 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 depart from the spirit of the present invention are within the scope of protection of the present invention.
