[0017] Beneficial Effects

[0018] The present invention provides a tire molding mold that is easy to demould. Compared with the prior art, the present invention has the following advantages:

[0019] Beneficial effects:

[0020] 1. The tire molding mold which is easy to demold, after the tire is molded and cooled, the longitudinal side plate is retracted first, and then the transverse side plate is retracted, and then the upper inner mold is moved downward, so that the tire and the inner mold are in a relatively relaxed state, and the tire is peeled from the lower inner mold to the upper inner mold, and then the upper inner mold is moved up to a suitable position, and finally the tire is peeled from the upper inner mold, and the demolding process of the tire can be easily completed, avoiding damage to the tire surface due to excessive demolding external force, reducing mold wear, and increasing the service life of the mold.

[0021] 2. The tire molding mold that is easy to demould, after the motor is started, drives the bidirectional screw to rotate. Since the threaded block on the bidirectional screw is slidably connected with the first guide rod, the threaded block is restricted to move only along the axial direction of the screw. When the threaded block moves, the connecting rod is driven to move through the first rotating seat, and the connecting rod pulls the longitudinal moving side plate to move laterally to both sides through the second rotating seat. On the one hand, the U-shaped fixing frame supports the rotation of the bidirectional screw, and on the other hand, the first guide rod inside it ensures that the threaded block moves stably, and finally the longitudinal moving side plate is separated from the inner side of the tire.

[0022] 3. The tire molding mold which is easy to demould is started by the electric push rod, and its telescopic end pulls the push block connected to it. Because the outer wall of the push block is sleeved in the first guide seat fixed to the inner bottom surface of the bottom tube, the push block can only move smoothly along the predetermined direction, thereby driving the lateral movement of the lateral side plate connected to it. At the same time, the guide plate symmetrical on the inner wall of the lateral side plate is sleeved in the second guide seat fixed to the inner bottom surface of the bottom tube, further ensuring the stability of the movement of the lateral side plate, and finally realizing the separation of the lateral side plate from the inner side of the tire.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The present invention provides a technical solution:

[0034] See also Figure 1-8 A tire molding mold that is easy to demould comprises a machine platform 1, a mounting hole 13 is provided through the top of the machine platform 1 near the middle position, an outer mold mechanism 2 is provided on the top of the machine platform 1, an inner mold mechanism is provided inside the outer mold mechanism 2, and the inner mold mechanism comprises:

[0035] The vertical opening and closing assembly 3 includes a bottom cylinder 31 and a top cylinder 33, which are arranged in an upper and lower manner. The bottom cylinder 31 is fixedly mounted on the inner wall of the mounting hole 13, and a lower inner mold 32 is fixedly sleeved on the outer wall of the bottom cylinder 31 near the top, and an upper inner mold 34 is fixedly sleeved on the outer wall of the top cylinder 33 near the bottom;

[0036] The longitudinal opening and closing assembly 4 is arranged between the lower inner mold 32 and the upper inner mold 34. The longitudinal opening and closing assembly 4 includes two longitudinally movable side plates 48 which are arranged symmetrically in front and back;

[0037] The transverse opening and closing assembly 5 is arranged between the lower inner mold 32 and the upper inner mold 34 , and the transverse opening and closing assembly 5 includes two transverse side plates 55 which are arranged in a left-right symmetrical manner.

[0038] The top surfaces of the longitudinal side plate 48 and the transverse side plate 55 can be fitted with the bottom surface of the upper inner mold 34, and the bottom surfaces can be fitted with the top surface of the lower inner mold 32. The side surfaces of the longitudinal side plate 48 and the transverse side plate 55 can form an annular structure by fitting together, and the outer diameter of the annular structure is equal to the outer diameter of the upper inner mold 34 and the lower inner mold 32.

[0039] Specifically, the longitudinal side plate 48 in the longitudinal opening and closing component 4 can be translated longitudinally, and the transverse side plate 55 in the transverse opening and closing component 5 can be translated transversely. By moving the longitudinal side plate 48 and the transverse side plate 55 to positions with the same diameter as the lower inner mold 32 and the upper inner mold 34, it is convenient to perform injection molding of the tire. After the tire is molded and cooled, the longitudinal side plate 48 is retracted first, and then the transverse side plate 55 is retracted, and then the upper inner mold 34 is moved downward, so that the tire and the inner mold are in a relatively relaxed state, and the tire is peeled off from the lower inner mold 32 to the upper inner mold 34, and then the upper inner mold 34 is moved up to a suitable position, and finally the tire is peeled off from the upper inner mold 34, the demolding process of the tire can be easily completed, thereby avoiding damage to the tire surface due to excessive demolding external force, reducing mold wear, and increasing the service life of the mold.

[0040] In this embodiment, the outer mold mechanism 2 includes two outer molds 21 that are symmetrically arranged on the left and right. The outer mold 21 is slidably arranged on the top of the machine 1. The inner wall of the outer mold 21 can fit with the outer wall of the bottom cylinder 31 and the top cylinder 33. A tire molding cavity is formed between the inner cavity of the outer mold 21 and the outer walls of the lower inner mold 32, the upper inner mold 34, the longitudinal side plate 48 and the transverse side plate 55. A glue injection port 23 is provided on the top of the outer mold 21. The outer mold mechanism 2 also includes a first hydraulic rod 22 fixedly installed on the top of the machine 1, which is used to drive the outer mold 21 to open or close the mold.

[0041] Specifically, the two outer molds 21 are pushed or pulled to close or open the molds by the first hydraulic rod 22, and the inner walls of the outer molds 21 fit the outer walls of the bottom tube 31 and the top tube 33. At this time, a tire molding cavity is formed between the inner cavity of the outer mold 21 and the outer walls of the lower inner mold 32, the upper inner mold 34, the longitudinal side plate 48 and the transverse side plate 55. The rubber raw materials can be injected into the molding cavity through the injection port 23 on the top of the outer mold 21.

[0042] In this embodiment, legs 11 are installed at the four corners of the bottom of the machine 1, and a mounting frame 12 is fixedly installed at a position near the rear side of the top of the machine 1. A lifting mechanism 6 is provided on the top of the mounting frame 12, and the lifting mechanism 6 includes a second hydraulic rod 61 fixedly installed on the top surface of the mounting frame 12. The telescopic end of the second hydraulic rod 61 slides through the top surface of the mounting frame 12 and extends downward. A connecting plate 62 is fixedly installed on the telescopic end of the second hydraulic rod 61, and a second guide rod 63 is symmetrically installed on the top surface of the connecting plate 62. The second guide rod 63 slides through the inner top surface of the mounting frame 12 and extends upward. The bottom surface of the connecting plate 62 is fixedly connected to the top surface of the top cylinder 33.

[0043] Specifically, the second hydraulic rod 61 can drive the connecting plate 62 to move up and down, thereby driving the top cylinder 33 to move up and down, thereby realizing the contact and separation of the upper inner mold 34 and the lower inner mold 32. The second guide rod 63 stabilizes the stability of the connecting plate 62 during the up and down movement process.

[0044] In this embodiment, the longitudinal opening and closing component 4 also includes a motor 41 installed on the bottom surface of the bottom cylinder 31, and the output shaft end of the motor 41 movably passes through the bottom surface of the bottom cylinder 31 and extends upward. A bidirectional screw rod 42 is installed on the output shaft end of the motor 41, and a thread block 43 is symmetrically threaded on the bidirectional screw rod 42. The front and rear sides of the thread block 43 are fixedly connected with a first rotating seat 45, and a connecting rod 46 is rotatably provided on the first rotating seat 45. A second rotating seat 47 is rotatably provided between the two connecting rods 46 on the same side, and the second rotating seat 47 is fixedly connected to the longitudinal movement side plate 48. The longitudinal opening and closing component 4 also includes a U-shaped fixing frame 49 installed on the inner bottom surface of the bottom cylinder 31. The top of the U-shaped fixing frame 49 is rotatably connected to the bidirectional screw rod 42 near the middle position. Two first guide rods 44 are fixedly connected between the inner top surface of the U-shaped fixing frame 49 and the inner bottom surface of the bottom cylinder 31. The first guide rods 44 pass through the thread block 43 and are slidably connected.

[0045] Specifically, after the motor 41 is started, it drives the bidirectional screw 42 to rotate. Since the threaded block 43 on the bidirectional screw 42 is slidably connected with the first guide rod 44, the threaded block 43 is restricted to move only along the axial direction of the screw. When the threaded block 43 moves, the connecting rod 46 is driven to move through the first rotating seat 45, and the connecting rod 46 pulls the longitudinal movement side plate 48 to move laterally to both sides through the second rotating seat 47. On the one hand, the U-shaped fixing frame 49 supports the rotation of the bidirectional screw 42, and on the other hand, the first guide rod 44 inside it ensures that the threaded block 43 moves stably, and finally the longitudinal movement side plate 48 is separated from the inner side of the tire.

[0046] In this embodiment, the transverse opening and closing component 5 also includes two fixed seats 51 that are arranged in a front-to-back and staggered manner. The fixed seats 51 are fixedly installed on the inner bottom surface of the bottom cylinder 31. An electric push rod 52 is installed on the top of the fixed seat 51. A push block 53 is installed on the telescopic end of the electric push rod 52. The two push blocks 53 are respectively fixedly connected to the two transverse side plates 55. The outer wall sliding sleeve of the push block 53 is provided with a first guide seat 54. The bottom surface of the first guide seat 54 is fixedly connected to the inner bottom surface of the bottom cylinder 31. The inner wall of the transverse side plate 55 is symmetrically fixedly connected with a guide plate 56. The outer wall sliding sleeve of the guide plate 56 is provided with a second guide seat 57. The bottom surface of the second guide seat 57 is fixedly connected to the inner bottom surface of the bottom cylinder 31.

[0047] Specifically, after the electric push rod 52 is started, its telescopic end pulls the push block 53 connected to it. Since the outer wall of the push block 53 is sleeved in the first guide seat 54 fixed to the inner bottom surface of the bottom tube 31, the push block 53 can only move smoothly along a predetermined direction, thereby driving the transverse side plate 55 connected to it to move horizontally. At the same time, the guide plate 56 symmetrical on the inner wall of the transverse side plate 55 is sleeved in the second guide seat 57 fixed to the inner bottom surface of the bottom tube 31, further ensuring the stability of the movement of the transverse side plate 55, and finally achieving the separation of the transverse side plate 55 from the inner side of the tire.

[0048] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0049] Working principle: Before the tire is formed, the first hydraulic rod 22 of the outer mold mechanism 2 pushes the two outer molds 21 to close the mold, and the inner wall of the outer mold 21 fits the outer wall of the bottom tube 31 and the outer wall of the top tube 33. At this time, a tire molding cavity is formed between the inner cavity of the outer mold 21 and the outer walls of the lower inner mold 32, the upper inner mold 34, the longitudinal side plate 48 and the transverse side plate 55, and then the rubber raw material is injected through the injection port 23 at the top of the outer mold 21.

[0050] After molding and cooling are completed, when demoulding is required, the outer mold 21 is first pulled to open the mold by the first hydraulic rod 22 of the outer mold mechanism 2. Then, the motor 41 of the longitudinal opening and closing component 4 is started to drive the bidirectional screw 42 to rotate, and the two threaded blocks 43 approach each other, and the longitudinal side plate 48 is driven to shrink inward through the first rotating seat 45, the connecting rod 46 and the second rotating seat 47, so that the longitudinal side plate 48 is separated from the inner side of the tire. Subsequently, the electric push rod 52 of the transverse opening and closing component 5 is started, and the transverse side plate 55 is pulled inward by the push block 53 to shrink, so that the transverse side plate 55 is separated from the inner side of the tire. When the plates 55 are all moved to the inside of the lower inner mold 32, the second hydraulic rod 61 is started to push the cylinder 33 downward, so that the upper inner mold 34 is close to the lower inner mold 32. At this time, the inner width of the tire will not fit tightly with the mold, so that the tire and the inner mold are in a relatively loose state, and the tire can be easily peeled off from the lower inner mold 32 to the upper inner mold 34. After the upper inner mold 34 is driven to move up to a suitable position by the second hydraulic rod 61, the tire is then peeled off from the upper inner mold 34, and the demolding process of the tire can be easily completed, avoiding damage to the tire surface due to excessive demolding external force, reducing mold wear, and increasing the service life of the mold.
