Description

Technical Field

[0001] This utility model relates to the field of casting mold technology, specifically a cement cover plate casting mold with demolding protection function. Background Technology

[0002] Casting is a method of plastic processing. It generally does not apply pressure, has low requirements for the strength of equipment and molds, fewer restrictions on product dimensions, and results in low internal stress in the product. However, machining is required after casting. Currently, based on traditional casting, methods such as pouring, insert casting, pressure casting, rotational casting, and centrifugal casting have been derived.

[0003] According to a publicized cement cover plate casting mold (publication number: CN218535018U), after the cement cover plate is formed, the handle is rotated to drive the rotating rod to rotate. At the same time, the rotating rod drives the connecting plate and the connecting column to rotate. Simultaneously, the inner surface of the extended horizontal groove of the connecting column slides left and right, and the connecting column drives the T-block and the top plate to slide up and down. At the same time, the top plate lifts up the formed cement cover plate to complete the demolding.

[0004] The above-mentioned method can demold the cement cover plate. However, if the air inside the mold is not expelled when pouring cement into the mold, the cement will become relatively loose, which will increase the friction during demolding. As a result, the cement cover plate will break due to excessive friction during demolding, thus affecting its performance. Utility Model Content

[0005] The purpose of this invention is to provide a cement cover plate casting mold with demolding protection function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cement slab casting mold with demolding protection function, comprising a base, a mold fixedly mounted on the top of the base, a support rod fixedly mounted on the top of the base, a top plate fixedly mounted on the top of the support rod, a cylinder fixedly mounted on the top of the top plate, a piston rod connected to the output end of the cylinder, a pressure plate fixedly connected to the bottom of the piston rod by bolts, a striking mechanism and a leveling mechanism provided on the top of the base, the striking mechanism comprising:

[0007] A sliding rod, the bottom of which is fixedly installed on the top of the pressure plate, and a movable rod is slidably installed on the right side of the sliding rod;

[0008] A compression spring is provided, with its top fixedly installed at the bottom of a sliding rod, enabling the sliding rod to move the moving rod downwards first. The end of the compression spring away from the sliding rod is fixedly installed at the bottom of the moving rod groove. A compression block is fixedly installed on the right side of the moving rod, and a fixing block is fixedly installed on the left side of the mold.

[0009] Preferably, a rotating rod is rotatably mounted on the right side of the fixed block, a torsion spring is fixedly mounted on the right side of the fixed block, the end of the torsion spring away from the fixed block is fixedly mounted on the outer wall of the rotating rod, and an arc-shaped spring is fixedly mounted on the inner wall of the arc-shaped groove of the rotating rod, which enables the sliding block to return to its original position after being squeezed.

[0010] Preferably, a sliding block is fixedly installed at the end of the arc spring away from the rotating rod, the back of the sliding block is slidably installed in the arc groove of the rotating rod, and a striking hammer is fixedly installed on the outer wall of the rotating rod.

[0011] Preferably, the leveling mechanism includes: a movable column, the outer wall of which penetrates the top of the sliding rod and is slidably connected at the penetration point; a tension spring is fixedly installed on the top of the sliding rod, which enables the sliding rod to push the movable column downward first.

[0012] Preferably, the end of the tension spring away from the sliding rod is fixedly installed at the bottom of the top protrusion of the moving column, a connecting rod is fixedly installed at the bottom of the moving column, a connecting rod is hinged to the back of the connecting rod, and a scraper is hinged to the end of the connecting rod away from the connecting rod.

[0013] Preferably, the bottom of the scraper is slidably mounted on the top of the mold, and a return spring is fixedly mounted on the right side of the scraper. This allows the scraper to be pulled by the tension force of the return spring, in case the angle of the connecting rod pushing the connecting rod is too small when the pressure plate is reset, making it impossible to push the scraper. The end of the return spring away from the scraper is fixedly mounted with a storage block, which can store the return spring and prevent the scraper from moving excessively. The left side of the storage block is fixedly mounted on the right side of the mold.

[0014] Compared with the prior art, this utility model provides a cement cover plate casting mold with demolding protection function, which has the following beneficial effects:

[0015] 1. This cement cover plate casting mold with demolding protection function works by starting the cylinder to push the piston rod to flatten the cement in the mold by pressing the pressure plate. The pressure plate moves downward, which drives the sliding rod to move downward. When it moves to a certain distance, the extrusion block will squeeze the sliding block, causing the rotating rod to rotate. After the extrusion is completed, the torsion spring will reset the rotating rod, causing the hammer to strike the outer wall of the mold. This will cause the mold to vibrate, expel the air inside the mold, and make the cement more compact. This will reduce the friction between the mold and the cement cover plate during demolding and prevent the cement cover plate from breaking due to excessive friction during demolding.

[0016] 2. This cement cover plate casting mold with demolding protection function, when the sliding rod moves down, it will drive the moving column to move down. At this time, the reset force of the return spring and the pressure of the connecting rod squeezing the connecting rod can make the scraper slide above the mold. Conversely, when the sliding rod rises, it will pull the connecting rod, causing the connecting rod to pull the scraper to reset. This can clean the surface of the mold and prevent excess cement from solidifying with the cement cover plate. In this way, the cement cover plate may be damaged when cleaning up excess cement.

[0022] like Figures 1-4As shown, this utility model provides a technical solution: a cement slab casting mold with demolding protection function, including a base 1, a mold 2 fixedly installed on the top of the base 1, a support rod 3 fixedly installed on the top of the base 1, a top plate 4 fixedly installed on the top of the support rod 3, a cylinder 5 fixedly installed on the top of the top plate 4, a piston rod 6 connected to the piston at the output end of the cylinder 5, a pressure plate 7 fixedly connected to the bottom of the piston rod 6 by bolts, a striking mechanism 8 and a leveling mechanism 9 are provided on the top of the base 1.

[0023] Specifically, the striking mechanism 8 includes: a sliding rod 81, a moving rod 82, a compression spring 83, a compression block 84, a fixed block 85, a rotating rod 86, a torsion spring 87, an arc spring 88, a sliding block 89, and a striking hammer 810. The bottom of the sliding rod 81 is fixedly installed on the top of the pressure plate 7. The moving rod 82 is slidably installed on the right side of the sliding rod 81. The top of the compression spring 83 is fixedly installed on the bottom of the sliding rod 81. When the pressure plate 7 moves downward, it will drive the sliding rod 81 to move downward. During movement, the compression spring 83 is activated, causing the moving rod 82 to move downwards. When the moving rod 82 moves to contact with the base 1, the sliding rod 81 continues to move downwards within the groove of the moving rod 82, and the compression spring 83 is compressed. The end of the compression spring 83 furthest from the sliding rod 81 is fixedly installed at the bottom of the groove of the moving rod 82. A compression block 84 is fixedly installed on the right side of the moving rod 82, and a fixing block 85 is fixedly installed on the left side of the mold 2. A rotating rod 86 is rotatably installed on the right side of the fixing block 85. A torsion spring 87 is fixedly installed on the right side of the fixed block 85. The end of the torsion spring 87 away from the fixed block 85 is fixedly installed on the outer wall of the rotating rod 86. An arc spring 88 is fixedly installed on the inner wall of the arc groove of the rotating rod 86. A sliding block 89 is fixedly installed on the end of the arc spring 88 away from the rotating rod 86. The back of the sliding block 89 is slidably installed in the arc groove of the rotating rod 86. A striking hammer 810 is fixedly installed on the outer wall of the rotating rod 86. When the moving rod 82 moves a certain distance, the pressing block 84 on the moving rod 82 will press the sliding block 89. Rotating rod 86 causes the torsion spring 87 to twist, and the hammer 810 rotates along with the rotating rod 86. When the compression reaches a certain level, the compression block 84 will disengage from the sliding block 89. At this time, the torsion spring 87 will reset the rotating rod 86, causing the hammer 810 to strike the outer wall of the mold 2. This will cause the mold 2 to vibrate, expel the air inside the mold 2, and make the cement more compact. This will reduce the friction between the mold 2 and the cement cover plate during demolding, and prevent the cement cover plate from breaking due to excessive friction during demolding.

[0024] Specifically, the leveling mechanism 9 includes: a moving column 91, a tension spring 92, a connecting rod 93, a connecting rod 94, a scraper 95, a return spring 96, and a storage block 97. The outer wall of the moving column 91 penetrates the top of the sliding rod 81, and the penetration point is slidably connected. The tension spring 92 is fixedly installed on the top of the sliding rod 81. The end of the tension spring 92 away from the sliding rod 81 is fixedly installed on the bottom of the top protrusion of the moving column 91. The connecting rod 93 is fixedly installed on the bottom of the moving column 91. The connecting rod 94 is hinged to the back of the connecting rod 93. The scraper 95 is hinged to the end of the connecting rod 94 away from the connecting rod 93. The bottom of the scraper 95 is slidably installed on the top of the mold 2. The return spring 96 is fixedly installed on the right side of the scraper 95. When the sliding rod 91 moves downward, it will drive the moving column 91 downward, causing the connecting rod 93 to move downward. At this time, the reset force of the return spring 96 and the pressure of the connecting rod 93 pressing the connecting rod 94 can make the scraper 95 slide above the mold 2. This can clean the surface of the mold 2 and prevent excess cement from solidifying with the cement cover plate. In this way, the cement cover plate may be damaged when cleaning the excess cement. The end of the return spring 96 away from the scraper 95 is fixedly installed with a storage block 97. The left side of the storage block 97 is fixedly installed on the right side of the mold 2. When the scraper 95 contacts the storage block 97, the sliding rod 81 continues to move downward and slides down on the moving column 91, and the tension spring 92 is stretched.

[0025] Working principle: When the cylinder 5 is activated, the piston rod 6 pushes the pressure plate 7 to flatten the cement inside the mold 2. The downward movement of the pressure plate 7 causes the sliding rod 81 to move downwards. As the sliding rod 81 moves, it drives the compression spring 83, causing the moving rod 82 to move downwards. When it reaches a certain distance, the compression block 84 on the moving rod 82 compresses the sliding block 89, causing the rotating rod 86 to rotate. The torsion spring 87 also twists, and the striking hammer 810 rotates along with the rotating rod 86. After sufficient compression, the compression block 84 disengages from the sliding block 89. At this point, the torsion spring 87 resets the rotating rod 86, causing the striking hammer 810 to strike the outer wall of the mold 2. This vibration causes the mold 2 to flatten the cement. Air is expelled from the interior of mold 2, making the cement more compact. When the moving rod 82 moves to fit against the base 1, the sliding rod 81 continues to move downward in the groove of the moving rod 82, and the compression spring 83 is compressed. Conversely, when the sliding rod 81 rises to a certain extent, it will drive the moving rod 82 to rise. At this time, when the extrusion block 84 extrudes the sliding block 89, because the hammer 810 is in contact with the outer wall of the mold 2, the sliding block 89 will slide in the arc groove of the rotating rod 86, and the arc spring 88 will be compressed. After the extrusion is complete, the arc spring 88 will reset the sliding block 89. This can reduce the friction between the mold 2 and the cement cover plate during demolding and prevent the cement cover plate from being damaged due to excessive friction during demolding.

[0026] When the sliding rod 81 moves downward, it drives the moving column 91 downward, causing the connecting rod 93 to move downward. At this time, the reset force of the return spring 96 and the pressure of the connecting rod 93 pressing against the connecting rod 94 allow the scraper 95 to slide above the mold 2. When the scraper 95 contacts the receiving block 97, the sliding rod 81 continues to move downward and slides down on the moving column 91, while the tension spring 92 is stretched. Conversely, when the sliding rod 81 rises, the tension spring 92 is reset first, and then the moving column 91 is driven upward. At this time, the moving column 91 pulls the connecting rod 93, causing the connecting rod 94 to pull the scraper 95 back to its original position, and the return spring 96 is stretched. This can clean the surface of the mold 2 and prevent excess cement from solidifying with the cement cover plate. However, cleaning excess cement may damage the cement cover plate. The above provides a general and detailed description of this utility model, but modifications or improvements can be made based on this utility model, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit and concept of this utility model are within the scope of protection of this utility model.
