Description

Technical Field

[0001] This utility model belongs to the field of ceramic tile demolding technology, and in particular relates to a mold core for forming multi-directional dovetail groove back patterns of ceramic tiles that facilitates demolding. Background Technology

[0002] Dovetail grooves in ceramic tiles are a structural design used in the field of tile installation to enhance the stability of the installation. They are characterized by the width of the bottom of the groove being wider than the width of the opening, forming a unique dovetail shape. Most existing dovetail grooves in ceramic tiles are unidirectional, which results in a small contact area between the dovetail groove and the cement, leading to an unsatisfactory adhesion effect.

[0003] Currently, the core of the mold for bidirectional dovetail grooves in ceramic tiles is mostly a grid-shaped dovetail groove block. To facilitate demolding, the dovetail groove block is made of hard rubber. However, when pressing ceramic tiles, the material will squeeze the rubber dovetail groove block, which often results in the width of the groove opening being the same as the width of the groove bottom, thus making the ceramic tile unusable. To address this, we have proposed a mold core for forming multidirectional dovetail groove back patterns in ceramic tiles that facilitates demolding. Utility Model Content

[0004] The purpose of this invention is to provide a mold core for forming multi-directional dovetail groove back patterns in ceramic tiles that facilitates demolding. By setting up a demolding mechanism, specifically, the left and right side moving frames move upwards, and three moving strips move upwards together, along the inclined groove, pushing and squeezing moving block one away from fixed block one. When the left and right side moving frames reach their limit positions, moving strip one is flush with the top of fixed block one and moving block one. Subsequently, the front and back moving frames move upwards simultaneously, and three moving strips move upwards together, pushing and squeezing moving block two away from fixed block two along the inclined groove. When moving strip two reaches its limit position, its top is flush with the top of fixed block two and moving block two, and the front and back moving frames are locked. This structure achieves rapid and efficient molding and demolding by controlling the mutual approach and distance between fixed block one and moving block one, and between fixed block two and moving block two. This solves the problem that existing mold cores, which use hard rubber for easy demolding, cause material to squeeze the mold when pressing ceramic tiles, resulting in the dovetail groove of the ceramic tile having the same width at the bottom and opening.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

The front and back of the movable block 26 are in contact with the inner wall of the fixed box 1.

[0039] A specific application of this embodiment is as follows: In use, the left and right movable frames 31 are moved upwards simultaneously. At this time, the three movable bars 27 will move upwards at the same time. When the movable bars 27 move upwards, they will move along the inclined groove 32. At this time, the movable bars 27 will push and squeeze the movable block 24, making it away from the fixed block 23. When the movable block 24 moves away from the fixed block 23, it will squeeze the two springs 341 connected to it. At the same time, the U-shaped frame 241 at the bottom of the movable block 24 will slide in the slot 262. When the left and right movable frames 31 drive several movable bars 27 to the limit position, the movable bars 27 are flush with the top of the fixed block 23 and the movable block 24, and the locking post 33 is in the spring 33 Under the action of the elastic force, it will enter the locking groove 332. At this time, the two movable frames 31 on the left and right sides are locked. Then, the movable frames 31 on the front and back are moved up at the same time. At this time, the three movable bars 28 will move up at the same time and push and squeeze the movable block 26 along the inclined groove 32, so that it is away from the fixed block 25. At this time, the two springs 341 connected to the movable block 26 are squeezed. At the same time, when the movable block 26 moves, the slot 1 261 and slot 2 262 are respectively slidably limited to the U-shaped frame 231 and U-shaped frame 241. When the movable bar 28 moves up to the limit position, the top of the movable bar 28 is flush with the top of the fixed block 25 and the movable block 26. At the same time, the movable frames 31 on the front and back are locked.

[0040] At this point, the material can be poured into the mold box 11 and evenly filled. Then, the material is pressed down using a hydraulic press. The material cannot enter the transverse dovetail groove block formed by the fixed block 23, the movable block 24, and the movable strip 27, nor can it enter the longitudinal dovetail groove block formed by the fixed block 25, the movable block 26, and the movable strip 28. After the material solidifies, the two locking pins 33 on the front and back are pulled out simultaneously. At this time, the two springs 331 on the front and back are compressed. Then, the movable frames 31 on the front and back are pressed down simultaneously, so that the bottom of the three movable strips 28 contacts the bottom of the inner wall of the fixed groove 22. During this process, when the movable block 26 loses its compression, the two springs 341 connected to it will push the movable block 26 towards the fixed block 25. Move 25 and contact the fixed block 25. Then, release the left and right moving frames 31 in the same way and press down so that the bottom of the moving strip 27 contacts the bottom of the fixed groove 21. At this time, the moving block 24 will be pushed towards the fixed block 23 by the two springs 341 connected to it, and finally contact the fixed block 23. At this time, while shaking, move the tile 12 upward so that the dovetail groove 121 no longer contacts the fixed block 23, the moving block 24, the fixed block 25 and the moving block 26. Then the tile 12 can be removed. The rubber covering the outer surface of the fixed block 23, the moving block 24, the fixed block 25, the moving block 26, the moving strip 27 and the moving strip 28 can prevent material leakage when the dovetail groove block is formed.
