Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically a solid tire mold. Background Technology

[0002] Solid tires are typically made of elastic materials such as rubber (e.g., natural rubber, styrene-butadiene rubber) or polyurethane. These materials exhibit high elasticity and toughness after vulcanization or curing. During molding, the material adheres tightly to the mold cavity. After cooling or curing, it may experience a "clamping" effect due to elastic contraction. This results in a large contact area between the material and the mold, significantly increasing friction and requiring greater elastic resistance to be overcome during demolding. Some materials (such as certain rubbers) may undergo slight chemical adsorption or physical adhesion to the mold surface after high-temperature vulcanization, further increasing demolding resistance. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5The present invention provides a solid tire mold, comprising: a base plate 1, a fixed platform 2 on the top of the base plate 1, a lower mold 3 and an upper mold 4 mounted on the fixed platform 2, and further comprising: a movable rod 5 movably inserted into the middle of the outer wall of the fixed platform 2, a driving assembly 6 mounted on the bottom outer wall of the fixed platform 2, one end of the driving assembly 6 being rotatably connected to the movable rod 5, a plurality of equidistantly distributed traction rods 7 being rotatably mounted on the outer wall of the movable rod 5, a plurality of equidistantly distributed fixing openings 8 being opened on the inner wall of the lower mold 3, a plurality of equidistantly distributed sealing shells 9 being mounted on the outer wall of the inner ring of the lower mold 3, and an air suction valve 10 being mounted on the top of the sealing shell 9, one end of the traction rod 7 being rotatably connected to an air extraction assembly 11, and a connecting plate 12 being mounted on the outer wall of the air extraction assembly 11, with impact assemblies 13 movably inserted at both ends of the connecting plate 12.

[0020] It should be noted that: the base plate 1 provides stable support for the entire mold; the fixed platform 2 is installed on top of the base plate 1 to support the lower mold 3 and the upper mold 4, forming the cavity for solid tire molding; the drive assembly 6 provides power to drive the movable rod 5, which is movably inserted into the middle of the outer wall of the fixed platform 2, to reciprocate; multiple traction rods 7 rotatably installed on the outer wall of the movable rod 5 will be driven by the movement of the movable rod 5, thereby pulling the air extraction assembly 11 rotatably connected to it; during the movement, the air extraction assembly 11, in conjunction with the sealing shell 9 installed on the outer wall of the inner ring of the lower mold 3 and the air extraction valve 10 on its top, can change the air pressure in the sealed space, reducing the adsorption force between the solid tire and the mold cavity; at the same time, the impact components 13 at both ends of the connecting plate 12 installed on the outer wall of the air extraction assembly 11 will impact the outer wall of the inner ring of the lower mold 3 as the air extraction assembly 11 moves, creating a gap between the two, reducing the tightness of the fit, thereby assisting demolding.

[0021] In a preferred embodiment, the drive assembly 6 includes a motor 601, a turntable 602 mounted on one end of the output shaft of the motor 601, an eccentric rod 603 mounted on an eccentric position of the turntable 602, and a connecting rod 604 rotatably connected to the eccentric rod 603; the top of the connecting rod 604 is rotatably connected to the bottom of the movable rod 5.

[0022] It should be noted that after the motor 601 starts, its output shaft drives the turntable 602 to rotate. Since the eccentric rod 603 is installed at an eccentric position on the turntable 602, the eccentric rod 603 will move in a circular motion with the turntable 602. Rotating the connecting rod 604 connected to the eccentric rod 603 will generate a pushing and pulling action along with the circular motion of the eccentric rod 603, thereby driving the movable rod 5 to reciprocate.

[0023] In a preferred embodiment, the vacuum assembly 11 includes a pull rod 1101 and an arc-shaped plate 1102 installed at one end of the pull rod 1101; the arc-shaped plate 1102 is adapted to the inner wall of the sealing shell 9, and the pull rod 1101 moves through the sealing shell 9.

[0024] It should be noted that: the arc-shaped plate 1102 is adapted to the inner wall of the sealing shell 9, so that the arc-shaped plate 1102 can form a relatively sealed space when it moves inside the sealing shell 9; when the traction rod 7 drives the pull rod 1101 to reciprocate, the arc-shaped plate 1102 will move synchronously inside the sealing shell 9. When the arc-shaped plate 1102 moves away from the inside of the sealing shell 9, a negative pressure is formed inside the sealing shell 9, the suction valve 10 opens, and the air between the solid tire and the mold cavity can be extracted to reduce the adsorption force between the two; when the arc-shaped plate 1102 moves in the opposite direction, it can balance the air pressure inside the sealing shell 9.

[0025] In a preferred embodiment, the impact assembly 13 includes an impact rod 1301, a spring 1302 sleeved on the outside of the impact rod 1301, and an impact ball 1303 mounted on one end of the impact rod 1301.

[0026] It should be noted that when the vacuum assembly 11 moves, the connecting plate 12 drives the impact assembly 13 to move synchronously, and the impact ball 1303 will impact the outer wall of the inner ring of the lower mold 3. During the impact, the spring 1302 is compressed, which plays a buffering role and stores elastic potential energy at the same time; after the impact, the spring 1302 returns to its original position, which drives the impact ball 1303 to return to its original position. This elastic impact can create a small gap between the solid tire and the mold, reduce the tightness of the fit, and facilitate demolding.

[0027] Working principle: Power transmission: After the drive component 6 at the bottom of the fixed platform 2 is started, the rotational motion is converted into the reciprocating motion of the movable rod 5. The movable rod 5 transmits the power to the suction component 11 and the impact component 13 through the traction rod 7, providing the power basis for the demolding auxiliary action;

[0028] Negative pressure to reduce adhesion: When the air extraction component 11 moves with the traction rod 7, its arc plate 1102 moves back and forth in the sealing shell 9, which, together with the air extraction valve 10, forms a negative pressure to extract the air between the solid tire and the lower mold 3 cavity, reducing the physical adsorption and adhesion between the two.

[0029] Elastic impact: The connecting plate 12 on the outer wall of the suction component 11 drives the impact component 13 to move synchronously. The impact ball 1303 impacts the outer wall of the inner ring of the lower mold 3 through the elastic buffer of the spring 1302, so that a small gap is generated between the two, reducing the tightness of the fit.

[0030] Details of the working principle of core components:

[0031] Drive component 6: Motor 601 drives turntable 602 to rotate, and eccentric rod 603 converts the circular motion into the reciprocating linear motion of movable rod 5 through connecting rod 604, providing power for subsequent components;

[0032] Air extraction assembly 11: The pull rod 1101 drives the arc plate 1102 to move inside the sealing shell 9, using the air pressure difference to reduce the adsorption force between the solid tire and the cavity, and the air extraction valve 10 balances the air pressure.

[0033] Impact assembly 13: The spring 1302 on the impact rod 1301 buffers the impact force, and the impact ball 1303 generates a gap through elastic impact to assist in separating the solid tire from the mold.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
