The bicycle tube forming fluid in the injection device is discharged from the injection container seat through the injection head installed on the top.

[0009] The top surface of the injection container seat is equipped with a pressure-maintaining tube that can be replaced according to the specifications of the bicycle tube. A positioning tube is inserted inside the pressure-maintaining tube. The bicycle tube material discharged from the injection container seat flows evenly into the cavity formed between the pressure-maintaining tube and the positioning tube through the discharge port opened on the outer wall of the positioning tube. With the high temperature applied to the outside of the pressure-maintaining tube, the bicycle tube material is shaped and cured.

[0010] Furthermore, several positioning grooves are provided around the top surface of the liquid injection container seat. These positioning grooves are evenly distributed at equal angles along the center of the top surface of the liquid injection container seat. Threaded tiles for assembling pressure-maintaining pipes are installed in the positioning grooves under the same circumference.

[0011] Furthermore, multiple sets of positioning grooves are arranged on the same circumference of the top surface of the liquid injection container seat, with the same spacing between each set of positioning grooves, so that the screw-on tiles can be securely installed on the top surface of the liquid injection container seat.

[0012] Furthermore, threaded grooves are provided on both the inner and outer sides of the screw-connected tile, and a thread is fixed at one end of the pressure pipe surface along the axial direction, with the thread and the threaded groove being compatible.

[0013] Furthermore, a sealing plug is screwed to one end of the positioning tube at its axial position, and a force-bearing handle is fixed to the top surface of the sealing plug. The sealing plug is adapted to the pressure-maintaining tube and is used to seal the cavity.

[0014] Furthermore, a plug-in valve body is installed on the end of the positioning tube that is axially away from the sealing plug, and the plug-in valve body is compatible with the injection head.

[0015] Furthermore, the outer periphery of the plug valve body is in contact with the inner wall of the pressure-maintaining tube, and multiple discharge ports are provided, which are evenly distributed on the axial position of the positioning tube surface.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This bicycle tube stamping integrated molding machine, through its replaceable screw-connected tile design, allows operators to disassemble and assemble mold components simply by turning the pressure-maintaining tube. This shortens the downtime and debugging time required for traditional mold changes, reduces space occupation, and minimizes large-scale resource investment. Furthermore, the axially distributed discharge port array on the surface of the positioning tube, combined with the external temperature control system of the pressure-maintaining tube, enables the molding liquid to form a spiral filling trajectory under pressure, effectively preventing the generation of air bubbles while improving the uniformity of material crystallization.

[0023] Before understanding the technical solution proposed in this application, it is important to understand that the probability of stamping in this application specifically refers to the process concept of stamping, which specifically refers to the rapid filling of liquid molding material into a preset cavity through a combination of high-pressure liquid injection and mold shaping, followed by pressure holding and curing to form a tubular structure.

[0024] like Figs. 1-3 As shown, it includes: a liquid injection container seat 4 for temporarily storing bicycle tube forming liquid, which is connected to the liquid injection device through a filling connector 3 installed on the outside.

[0025] It should be noted that the injection container seat 4 is made of corrosion-resistant alloy material. The bicycle tube molding liquid in the injection device is smoothly discharged from the injection container seat 4 through the injection head 8 installed on the top. In addition, during actual use, the bottom of the injection container seat 4 is equipped with an adjustable support bracket to ensure the horizontal stability of the equipment during operation.

[0026] It should be added that, in actual use, the top surface of the injection container seat 4 is equipped with a replaceable pressure tube 1 according to the specifications of the bicycle tube. The pressure tube 1 is made of high-temperature hardened ceramic composite material, and a positioning tube 6 is inserted inside it. The bicycle tube molding liquid discharged from the injection container seat 4 flows evenly into the annular cavity formed between the pressure tube 1 and the positioning tube 6 through the discharge port 5 opened on the outer wall of the positioning tube 6. It should be noted that when hot air at 150-180℃ passes through the electromagnetic heating ring outside the pressure tube 1, the molding liquid in the cavity can complete the phase change and solidification within 30 seconds, accurately replicating the mold outline of the bicycle tube.

[0027] It is worth noting that in this application, the bicycle tube molding fluid is specifically a mixture of acrylate-based polyurethane resin and nano-silica reinforcing agent, with a mass ratio of 85:15, and 2%-3% benzoyl peroxide is added as a free radical initiator.

[0028] As a preferred embodiment, in this embodiment, 24 sets of positioning grooves are provided around the top surface of the injection container seat 4. The positioning grooves, which are precision machined by CNC, are evenly distributed at a 15-degree angle along the center of the top surface. Each set of positioning grooves is embedded with a wear-resistant copper liner. The positioning grooves under the same circumference are installed with screw-connecting tiles 9 for assembling the pressure-maintaining tube 1 through dovetail guide rails. It should be added that the spacing between the rows of positioning grooves under the same circumference on the top surface of the injection container seat 4 is the same, and the inner and outer sides of the screw-connecting tiles 9 are provided with 60-degree V-shaped thread grooves, which form a double locking structure with the trapezoidal threads machined at the axial end of the pressure-maintaining tube 1.

[0029] As a preferred embodiment, in this embodiment, the sealing plug 2 configured at the axial end of the positioning tube 6 is made of fluororubber, and the corrugated force-bearing handle fixed on its top surface conforms to the ergonomic design. When the sealing plug 2 is screwed into the pressure tube 1, the built-in O-ring seal forms a triple radial seal with the tube wall.

[0030] As a preferred embodiment, in this embodiment, the first end of the positioning tube 6 is fixed with a plug valve body 7. The plug valve body 7 and the conical sealing interface of the injection head 8 form an interference fit. The outer surface of the plug valve body 7 is hard chrome plated and maintains a sliding fit with the inner wall of the pressure tube 1 to ensure that the bicycle tube molding liquid does not produce a wall adsorption effect when flowing. In addition, it should be noted that the discharge port 5 is equidistantly distributed in 12 groups along the axial direction of the positioning tube 6. Each group contains 6 oblique spray holes with a diameter of 2mm. The axis of the spray hole is at a 45-degree angle to the tube wall to achieve a spiral injection effect.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
