Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Examples
As shown in fig. 1, the centrifugal device for producing a tire by using a polyurethane elastomer mold comprises a polyurethane elastomer mold 10 and a power device for driving the mold 10 to rotate, wherein the power device comprises a rotating part 21 for placing the mold 10 and enabling the mold 10 to rotate through static friction, and a pressing part 22 which is arranged right above the rotating part 21, moves towards the rotating part 21, is matched with the rotating part 21 to clamp the mold 10 and rotates along with the mold 10, the rotating axes of the rotating part 21, the mold 10 and the pressing part 22 are collinear, the mold 10 comprises an upper mold 11 and a lower mold 12, a feeding hole 111 for feeding polyurethane foaming slurry and collinear with the rotating axis of the mold 10 is arranged at the top of the upper mold 11, and a pouring hole 221 which is coaxial with the rotating axis is arranged on the pressing part 22.
Traditional centrifugal device for polyurethane foam tire production all need fix metal mold on the rolling disc of bottom, so inconvenient dismantlement of mould in the time of the drawing of patterns leads to the tire drawing of patterns also to have not convenient problem. The invention adopts polyurethane elastomer raw materials as the mould 10, has the characteristics of light weight, fixed shape and small deformation, and is very suitable for being used as the mould, and the performances of the upper mould 11 and the lower mould 12 made of the polyurethane elastomer raw materials are similar to those of rubber, and a sealing rubber gasket is not required to be additionally added to ensure the sealing performance during mould closing; the production of the mold 10 is lower in cost and more convenient, and only an enterprise needs to be entrusted to produce a set of metal mold matrix in the earlier stage, so that the tire manufacturing enterprise can directly utilize the polyurethane elastomer raw materials to match with the mold matrix to manufacture the mold 10 for producing the tire, and the production cost of the mold is greatly reduced. In the production process, an upper die 11 and a lower die 12 are directly clamped and placed on the surface of a rotating part 21, then a pressing part 22 is controlled to move downwards to press a die 10 on the surface of the rotating part 21, the friction force between the die 10 and the rotating part 21 is improved through clamping, after the rotating part 21 is controlled to rotate, the die 10 is driven by the rotating part 21 to rotate under the action of static friction force, because the pressing part 22 can rotate along with the die 10, the rotation of the die 10 cannot be influenced when the die 10 rotates, polyurethane foaming slurry is filled into a cavity of the die 10 through a filling hole 221 and a feeding hole 111 while the die 10 rotates, the tire can be formed after centrifugation for 5 minutes, the rotating part 21 is stopped, after the pressing part 22 is lifted, the die 10 can be easily taken out, and the next die 10 which is clamped is directly placed on the rotating part 21 to produce the next tire, the idle period of the centrifugal device during tire demoulding is reduced, and the production efficiency is improved. Moreover, because the mold 10 is only in surface contact with the rotating part 21 and the pressing part 22 is matched to transmit the rotating energy to the mold 10, no mechanical connecting part exists, a great amount of time can be saved when the mold 10 is disassembled, and the production efficiency is greatly improved.
Although the mold 10 and the tire are both made of polyurethane, the mold 10 is made of one raw material of polyurethane, and needs to be cured by heating, has a high density, has high strength after curing, has reduced strength, and can withstand the pressure of the pressing portion 22; the tire is made of polyurethane as a main material, is mixed with other auxiliary agents such as a foaming agent and the like for use, can be cured and molded through short-time centrifugation, and is low in density and certain in elasticity, so that the tire is more suitable for manufacturing; in addition, a layer of liquid release agent needs to be coated on the inner surface of the cavity of the mold 10 during mold closing, so that the demolding operation after tire molding is facilitated.

Specifically, the platen 224 and the control frame 222 can rotate relative to each other through the bearing 223, so that the platen 224 can independently rotate along with the mold 10 after pressing the mold 10, the control frame 222 is used for driving the platen 224 to move up and down, the up and down movement of the control frame 222 can be realized through a hydraulic cylinder or a pneumatic cylinder (not shown in the figure), and the control frame 222 only needs to be fixedly connected to the tail end of a telescopic column of the hydraulic cylinder through welding or bolts.
As shown in fig. 1 and 3, the rotating part 21 includes a base 211 placed on a horizontal ground, a motor 212 fixedly installed in the base 211, and a turntable 213 rotatably disposed on the top of the base 211 and drivingly connected to an output shaft of the motor 212. The motor 212 is used for providing power to drive the turntable 213 to rotate, the motor 212 and the turntable 213 are driven by the gear engagement 215, and the motor 212 needs to be electrified to work, so that the start and stop of the motor 212 can be easily controlled to control the rotation of the turntable 213, and the mold 10 can be conveniently controlled to be assembled and disassembled. In addition, in order to control the rotation speed of the mold 10, a speed reducer can be installed at the output end of the motor 212, and the rotary connection between the turntable 213 and the base 211 can also be realized through a bearing.
The centrifugal device further comprises a PLC control system, the PLC control system is electrically connected with the motor 212 and the electromagnetic valve of the hydraulic cylinder, so that controllability and consistency of up-and-down movement of the control frame 222 are guaranteed, and deviation problems caused by manual operation are avoided.
