A tire mold protection structure

Abstract

The utility model is applicable to the technical field of tire mold protection, and provides a tire mold protection structure, including a pallet composed of a base frame, a support column, and a top plate, and a protection component. When transferred by a forklift pallet, the protection component moves up to limit the upper and lower side panels and the pattern module. The utility model sets a protection component. When the tire mold encounters bumps and vibrations during transfer, the arc-shaped limit block can limit the movement of the upper and lower side panels, and the straight-line limit block can limit the movement of the pattern module. At the same time, the arc-shaped limit block and the straight-line limit block can separate the upper and lower side panels and the pattern module from each other, thereby avoiding collisions between the upper and lower side panels and the pattern module. In addition, the protection baffle can separate external objects. When the forklift accidentally contacts with external objects during the transfer process, the upper and lower side panels and the pattern module can also be protected, thereby ensuring the safety of the mold during the transfer process.

Description

Technical Field

[0001] The utility model belongs to the technical field of tire mold protection, and in particular relates to a tire mold protection structure. Background Art

[0002] Tire molds refer to molds for vulcanizing various types of tires. There are two types of tire molds:

[0003] The first type is a flexible mold, which consists of a pattern ring, a mold sleeve, and upper and lower side plates; the second type is a two-half mold, which consists of an upper mold and a lower mold.

[0004] Tire molds are important tools used in the tire vulcanization process. During use, the mold is inevitably contaminated by the combined deposition of rubber, compounding agents, and release agents used in the vulcanization process (the main pollutants are sulfides, inorganic oxides, silicone oil, carbon black, etc.). Repeated use will cause some pattern contamination dead areas. Therefore, the mold must be cleaned regularly to ensure the cleanliness of its surface in order to ensure the quality of the tire and the life of the mold.

[0005] When cleaning existing flexible molds, most of them are disassembled and placed on a pallet, and multiple pattern modules and upper and lower side panels that make up the pattern circle are placed on a pallet, and then transferred as a whole to a cleaning workshop for laser cleaning by a forklift. During this process, the pattern modules and the upper and lower side panels are blocked and limited by each other. When the forklift is jolted or vibrated or suddenly stopped during the transfer, the pattern modules and the upper and lower side panels are easily offset and collided, which will affect the mold accuracy and may even cause the mold to be scrapped in severe cases. Based on this, a tire mold protection structure is provided. Utility Model Content

[0047] Four protective baffles 205 are provided, and the four protective baffles 205 are respectively distributed around the top plate 103 and fit with the periphery of the top plate 103. The protective baffles 205 that are moved upward and protrude above the top plate 103 are used to shield the area where the first limiting unit and the second limiting unit are located, so as to prevent external objects from contacting and colliding with the first limiting unit and the second limiting unit during the transfer of the tray 1;

[0048] The moving unit includes an extruded bottom plate 201, a square through hole 202 and a limiting slider 208;

[0049] The extrusion bottom plate 201 is distributed between the base frame 101 and the support column 102, and the square through hole 202 is opened at the top of the extrusion bottom plate 201 and penetrates the bottom of the extrusion bottom plate 201. The extrusion bottom plate 201 is slidably sleeved on the outside of the support column 102 through the square through hole 202, and the arc limit block 203 and the linear limit block 204 are fixed on the top of the extrusion bottom plate 201, and the protective baffle 205 is fixed around the extrusion bottom plate 201.

[0051] In this embodiment, when cleaning the tire mold, the disassembled upper and lower side plates 3 and the pattern module 4 are placed on the top of the circular pad 206 and the concave pad 207 respectively;

[0052] After that, the fork arm of the forklift is inserted between the bottom frame 101 and the extrusion bottom plate 201, and then the fork arm is lifted, the fork arm will squeeze the extrusion bottom plate 201 to make it move upward, and the extrusion bottom plate 201 will simultaneously push the arc limit block 203, the straight limit block 204 and the protective baffle 205 to move upward, the arc limit block 203 forms a wrap around the upper and lower side plates 3, the four straight limit blocks 204 in a group form a wrap around the pattern module 4, and the four protective baffles 205 form a shield around the top plate 103;

[0053] After that, the fork arm continues to rise to lift the pallet 1 as a whole off the ground, and then the pallet 1 is moved as a whole to the cleaning workshop by the forklift. During this process, when encountering bumps and vibrations, the arc limit block 203 can limit the movement of the upper and lower side panels 3, and the straight limit block 204 can limit the movement of the pattern module 4. At the same time, the arc limit block 203 and the straight limit block 204 can realize the separation of the upper and lower side panels 3 and the pattern module 4, thereby avoiding the upper and lower side panels and the pattern module from colliding with each other. In addition, the protective baffle 204 can separate external objects. When the forklift accidentally contacts with external objects during the transfer process, the upper and lower side panels 3 and the pattern module 4 can also be protected, thereby ensuring the safety of the mold during the transfer process.

[0054] After being transferred to the designated position, the forklift lowers the pallet 1 as a whole. At this time, the extrusion bottom plate 201, the arc limit block 203, the straight limit block 204 and the protective baffle 205 will move outward under their own gravity. Finally, the top of the arc limit block 203, the straight limit block 204 and the protective baffle 205 will be flush with the top of the top plate 103, which will not affect the cleaning operation of the upper and lower side plates 3 and the pattern module 4.

[0055] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the arc-shaped limit block 203, the linear limit block 204, the circular pad 206 and the concave pad 207 are all made of rubber material, and the protective baffle 205 is made of metal plate.

[0056] In this embodiment, the arc-shaped stopper 203, the linear stopper 204, the circular pad 206 and the concave pad 207 made of rubber material can prevent the upper and lower side plates 3 and the pattern module 4 from having a hard collision;

[0057] The protective baffle 205 made of metal sheet has good anti-deformation performance and can play an efficient anti-collision effect. It should also be noted that the protective baffle 205 can also block the gap between the extrusion bottom plate 201 and the top plate 103 to prevent the forklift fork arm from being inserted into the gap.

[0058] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the sizes of the circular pad 206 and the concave pad 207 are respectively larger than the outer wall sizes of the upper and lower side panels 3 and the pattern module 4. The upper and lower side panels 3 and the pattern module 4 are placed on the upper ends of the circular pad 206 and the concave pad 207 and do not contact the arc limit block 203 and the straight limit block 204.

[0059] In this embodiment, this structure can provide sufficient space for the placement of the upper and lower side panels 3 and the pattern module 4. The relative positions of the upper and lower side panels 3 and the pattern module 4 and the circular pads 206 and the concave pads 207 can be used to determine whether the upper and lower side panels 3 and the pattern module 4 are placed correctly, thereby avoiding interference between the upper and lower side panels 3 and the pattern module 4 and the upward movement of the arc limit blocks 203 and the straight limit blocks 204.
