[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Referring to Figures 1-4, a butyl inner tube shaping machine includes a base plate 1, a lower mold 2 mounted on the top of the base plate 1, a top plate 5 connected to the top of the base plate 1 via a support rod 4, an upper mold 3 connected to the bottom of the top plate 5 via a first electric telescopic rod 6, and forming cavities opened on the opposite surfaces of the lower mold 2 and the upper mold 3. A lead screw 14 is rotatably mounted on the top of the base plate 1, and an internal thread block 18 is threaded onto the lead screw 14. A limiting mechanism for limiting the internal thread block 18 is provided on the top of the base plate 1. A dust-adhesive ring 12 is connected to the side of the internal thread block 18 via a second electric telescopic rod 20. The outer surface of the dust-adhesive ring 12 is covered with a layer of dust-adhesive pad, and the size of the dust-adhesive ring 12 is the same as the size of the forming cavity.

[0024] As a technical optimization of this utility model, a motor 13 is installed on the top of the base plate 1. The output shaft of the motor 13 is connected to the lead screw 14. The rotation of the output shaft of the motor 13 can drive the lead screw 14 to rotate.

[0025] As a technical optimization of this utility model, the limiting mechanism includes a second slide rod 16 installed on the top of the base plate 1, a strip plate 15 installed on the top of the second slide rod 16, and a second sliding sleeve 17 installed on the side of the internal threaded block 18 away from the second electric telescopic rod 20. The second sliding sleeve 17 is slidably sleeved on the second slide rod 16. Through the cooperation of the second sliding sleeve 17 and the second slide rod 16, the internal threaded block 18 can be limited, so that the internal threaded block 18 can move up and down on the lead screw 14.

[0026] As a technical optimization of this utility model, a bearing 21 is installed at the bottom of the strip plate 15, the top of the lead screw 14 is installed on the inner ring of the bearing 21, a fixing plate 19 is installed on the side of the internal thread block 18 away from the second sliding sleeve 17, and the second electric telescopic rod 20 is installed on the side of the fixing plate 19 away from the internal thread block 18. The bearing 21 can provide guidance for the rotation of the lead screw 14.

[0027] As a technical optimization of this utility model, the outer wall of the adhesive pad is provided with a circular opening, and the piston rod of the second electric telescopic rod 20 is connected to the adhesive ring 12 through the circular opening. The circular opening facilitates the connection between the piston rod of the second electric telescopic rod 20 and the adhesive ring 12.

[0028] As a technical optimization of this utility model, the bottom end of the support rod 4 is installed on the top of the base plate 1, and the top end of the support rod 4 is installed on the bottom of the top plate 5. The piston rod end of the first electric telescopic rod 6 is equipped with a reinforcing block 7, which is fixed to the top of the upper mold 3. The reinforcing block 7 can increase the connection strength between the piston rod end of the first electric telescopic rod 6 and the upper mold 3.

[0029] As a technical optimization of this utility model, a first sliding sleeve 9 is installed on the outer wall of the upper mold 3, and a first sliding rod 10 is installed on the top of the bottom plate 1. The first sliding rod 10 is slidably installed in the first sliding sleeve 9, and a limit block 11 is installed at the top of the first sliding rod 10. Through the cooperation of the first sliding sleeve 9 and the first sliding rod 10, the upper mold 3 can be guided to move up and down.

[0030] As a technical optimization of this utility model, a connecting block 8 is installed on the outer wall of the upper mold 3, and the first sliding sleeve 9 is installed on the side of the connecting block 8 away from the upper mold 3. Two sets of mounting holes 22 are symmetrically opened on the top of the bottom plate 1. The connecting block 8 can facilitate the connection between the first sliding sleeve 9 and the upper mold 3, and the mounting holes 22 can facilitate the fixing of the bottom plate 1, thereby facilitating the fixing of this device.

[0031] When using this invention, if it is necessary to shape the butyl inner tube, firstly, the first electric telescopic rod 6 is activated. The piston rod of the first electric telescopic rod 6 pushes the upper mold 3 down until the bottom of the upper mold 3 contacts the top of the lower mold 2 and then stops. At this time, the shaping material of the butyl inner tube can be injected into the forming cavity between the upper mold 3 and the lower mold 2, and the butyl inner tube is shaped using the forming cavity between the upper mold 3 and the lower mold 2.

[0032] After the butyl inner tube is formed in the molding cavity, the first electric telescopic rod 6 is activated. The piston rod of the first electric telescopic rod 6 moves the upper mold 3 upward, and the formed butyl inner tube can then stay in the lower mold 2. At this time, the motor 13 is activated, and the output shaft of the motor 13 drives the lead screw 14 to rotate. The rotation of the lead screw 14 causes the internal thread block 18 to move up and down on the lead screw 14, which can adjust the height of the internal thread block 18. This, in turn, adjusts the height of the second electric telescopic rod 20 and the dust-adhesive ring 12, allowing the dust-adhesive ring 12 to be adjusted between the upper mold 3 and the lower mold 2. At this time, the second electric telescopic rod 20 is activated, and the piston rod of the second electric telescopic rod 20 pushes the dust-adhesive ring 12 to move laterally until the dust-adhesive ring 12 moves laterally to directly above the lower mold 2 and then stops. The dust-adhesive ring 12 is then moved laterally until it moves downward. The inner tube can then enter the molding cavity at the top of the lower mold 2. At this time, the motor 13 is started again, causing the lead screw 14 to rotate and move the internal thread block 18 downward, thereby causing the dust-adhesive ring 12 to move downward. The dust-adhesive ring 12 moves downward to the molding cavity at the top of the lower mold 2, and the dust-adhesive pad on the outer surface of the dust-adhesive ring 12 moves downward with the dust-adhesive ring 12 and comes into contact with the butyl inner tube that has been molded in the molding cavity at the top of the lower mold 2. The dust-adhesive pad on the outer surface of the dust-adhesive ring 12 can be used to adhere the butyl inner tube, thereby adhering the butyl inner tube in the molding cavity at the top of the lower mold 2 to the dust-adhesive pad. At this time, the dust-adhesive ring 12 is reset, and the molded butyl inner tube can be discharged. The molded butyl inner tube can be discharged without manual discharge, thus avoiding burns to workers due to high temperature from the newly molded butyl inner tube.

[0033] After the butyl inner tube is discharged, the dust-adhesive ring 12 is adjusted again to be directly above the molding cavity at the top of the lower mold 2. The dust-adhesive ring 12 moves downward, causing the dust-adhesive pad to move downward to adhere to the butyl inner tube flash that has fallen into the molding cavity at the top of the lower mold 2. The dust-adhesive ring 12 moves upward to adhere to the butyl inner tube flash in the molding cavity at the bottom of the upper mold 3. This can adhere and remove the butyl inner tube flash that has fallen into the molding cavities at the top of the lower mold 2 and the bottom of the upper mold 3, and at the same time adhere to the dust and impurities in the molding cavity, ensuring the cleanliness of the molding cavity.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
