Description of the Invention: [Technical Field] The present invention relates to a method for manufacturing a tire, and more particularly to a method for manufacturing a t-solid solid tire having better comfort. [Prior Art] The original tires used hollow tires, which were hollowed out in rubber and then placed on the hub of the wheel. When in use, air was filled into the hollow tire to produce good The shock absorption effect is therefore widely used. However, this type of hollow tire is easy to smash the tire when it encounters a projection such as a rock, so that the wheel cannot move, and the wheelchair is used in some special people such as a disabled person. Therefore, it is dangerous. Solid tires with good load bearing capacity emerged. Solid tires are generally made of rubber or foam. Even if the road is uneven on the road, there will be no puncture, etc. It is safe to use, however, due to the solid tire itself. The amount of deformation is small. When a rock or the like is encountered during driving, the solid tire transmits the force directly to the hub', resulting in poor comfort. In order to improve the comfort of the solid tire during driving, a hollow solid tire is formed, which fixes the airbag in the mold, and then rotates the entire mold at a high speed by using a turntable connected to the mold, and simultaneously injects the foam liquid into the cavity from the casting hole. Through the centrifugal force generated when the mold rotates, the foam material is uniformly filled into the cavity of the cavity and the foam material is tightly combined to form a space on the formed solid tire, which can buffer the effect from the outside to some extent. Force to improve the comfort of use of solid tires. However, during the manufacturing process, due to the uncertainty of the shape of the airbag itself 201139170, the centrifugal force generated by the airbag itself and the foamed material to the airbag during the rotation process cannot be surely in a predetermined position after the molded airbag is in the predetermined position. The deviation is such that during the driving process, the inner wall of the hollow solid tire is stressed and asymmetrical, thereby affecting the quality of the product. Due to the above analysis, the inventors have made research and improvement on the shortcomings of the current t-empty solid tires in the production process, and the present invention has been produced. SUMMARY OF THE INVENTION The main object of the present invention is to provide a method for producing a hollow solid tire. The hollow solid tire produced by the method has the advantages of stable quality, good cushioning effect and good comfort. In order to achieve the above object, the solution of the present invention is: a method for manufacturing a hollow solid tire, comprising the steps of: combining a plurality of modules into a core, and fixing the core in a tire forming mold; closing the mold Injecting the foaming liquid from the washing hole, filling the foaming liquid with the space between the inner wall of the mold and the core and solidifying; then taking out the tire and the core in the mold, disassembling the mold and taking out the module one by one, Thereby forming a hollow • solid tire. The above-described core includes a fixing portion that is fixed to the mold at the inner ring and a joint portion that is coupled to the tire at the outer ring. After adopting the above scheme, the present invention changes the manner in which the airbag is used to form a hollow space, and the hard core is used to form a hollow space on the solid tire, which has the following improvements: (1) Since the core is not subjected to centrifugal force during the pouring process The deformation is stable in the inner wall of the tire, which better guarantees the quality of the finished product; [S] 4 201139170 (2) The tire is made into a German, and the core is easy to disassemble the core, which is easy to remove from the tire. Affect the quality and shape of the tire; (7) The space formed on the tire can better provide the deformation space, increase the deformation of the solid tire, and the right rib is applied to the field from the pound, which helps to buffer the external force and improve the comfort of use. [Embodiment] The production flow of the present invention will be described in detail below with reference to the drawings and specific embodiments. The present invention provides a method for producing a hollow solid tire, which comprises the following steps: (1) Making a tire molding die! And the mold core 2, the mold 1 includes an upper mold u and a lower mold 12 that are mutually engageable, a center of the upper mold u is provided with a through pouring hole 13 , and a center of the lower mold 12 is provided with a lower inner mold 12 1 and A receiving cavity is formed between the lower inner mold 121 and the side wall of the lower mold 12, and the core 2 is annular. Referring to the second to fourth figures, it includes a fixing portion 21 at the inner ring and an outer ring. In the present embodiment, the fixing portion 21 and the joint portion 22 are respectively combined by six modules and locked by screws 23 respectively; the core 2 is placed in the lower mold 12 of the mold 1, And fixing the fixing portion 21 to the lower inner mold 121; (2) closing the tire molding die 1 and washing the foam material liquid into the mold 1 from the pouring hole 13 while rotating the mold 1 at a high speed to fill the foaming liquid The space between the inner wall of the mold 1 and the core 2, after the foam material is solidified, the foamed material is tightly combined with the joint portion 22 of the core 2; (3) the mold 1 is opened, and the formed tire and the core 2 are formed. - Take out from the mold 201139170 with 1; (4) Remove the screw 23, disassemble the mold 2, and take out the shape of each mold tire An annular space with the inner wall of a hollow solid tires. The hollow solid tire produced by the above method utilizes a rigid mold to form an annular space in front of the inner wall of the tire, and the mold 2 is hard and firm in the mold! When the high-speed rotation is not deformed, the shape of the formed annular space is self-contained, and the external force is evenly buffered during driving to improve the comfort of use; the material core 2 is assembled by a plurality of modules, which is convenient. Disassembly and assembly, after the foamed material and the core 2 are combined and cured, the mold core 2 can be taken out after being divided into parts, and the operation is simple, and the shape of the core 2 is not affected, and the material is not made into a material. Any impact. The above embodiments are only for explaining the technical idea of the present invention, and the scope of protection of the present invention is not limited thereto. Any changes made based on the technical idea according to the present invention fall within the protection scope of the present invention. Inside.
