Description

Technical Field

[0001] This utility model relates to the field of mold technology, and more specifically, to a molding mold for a sandstone-textured material surface. Background Technology

[0002] Rock climbing has become a popular and fashionable sport in recent years. Climbers use planks whose surfaces are designed to mimic the shapes of natural rocks. The planks are rectangular, and when connected, they form a wall. Climbing holds are provided on the planks for climbers to ascend. Molds are required during the construction of these holds. For example, CN221161236U discloses a device to prevent damage to the inner mold of a climbing hold, including a mold box. Extension plates are provided on both sides of the mold box, allowing it to be stretched and its length changed. A clamping plate is connected to one side of the extension plate. The length of the extension plate and clamp can be changed by stretching and moving it. One side of the extension plate can be attached to the outside of different sized mold boxes by changing the length of the extension plate and clamp. A tensioner is provided on one side of the extension plate. The tension generated by the tensioner causes the extension plate to be pulled and drives the clamp to be pulled, so that one side can be tightly attached to the outside of the mold box. After the silicone inside the mold box is cured to form the inner membrane of the climbing point, it will not break during the removal process, which facilitates the reuse of the mold box. Furthermore, by installing the roller assembly and clamp, the removal of the inner membrane of the climbing point is easier and will not damage its structure.

[0003] However, existing technologies have some problems: In order to facilitate subsequent demolding, the device pours liquid silicone onto the film and uses the weight of the liquid silicone to press the film against the inside of mold cavity one and mold cavity two. However, in actual use, the air in mold cavity one and mold cavity two is difficult to expel during the film extrusion process, which may result in gaps between the film and the mold cavity, thus affecting the forming structure of the climbing support and making it difficult to form a sandstone-textured surface. Therefore, we propose a molding die for a sandstone-textured material surface. Utility Model Content

[0004] One objective of this invention is to provide a new technology solution for molding dies that create a sandstone-like texture on the surface of a material.

[0005] According to a first aspect of this utility model, a molding die for a sandstone-like surface is provided, comprising a base, a mold block movably mounted on the base, two push rods movably inserted into the base, the tops of the two push rods penetrating the mold block, a washer fixedly mounted on the tops of the two push rods, two crossbars fixedly connected between the bottoms of the two push rods, the crossbars being connected to the base via a drive assembly, the drive assembly enabling the crossbars to drive the push rods upward, and a clamping assembly provided on the base for clamping and limiting the mold block.

[0006] Optionally, the drive assembly includes a bidirectional lead screw rotatably connected to the base, with sliders threaded onto both sides of the outer surface of the bidirectional lead screw, and a connecting rod hinged between the sliders and the crossbar.

[0007] Optionally, a guide rail is fixedly installed at the bottom of the base, the guide rail is slidably connected to the slider, and the outer surface of the guide rail is coated with a lubricating layer.

[0008] Optionally, the clamping assembly includes two square frames, which are respectively fixedly installed on both sides of the top of the base. A threaded rod is rotatably connected to the square frame, and a pressure plate is threaded onto the outer surface of the threaded rod.

[0009] Optionally, the pressure plate has a square groove, and a movable plate is slidably connected inside the square groove. The top of the movable plate has a top groove.

[0010] Optionally, a pin is movably inserted into the pressure plate, the bottom of the pin extends into the top groove, and a pull handle is fixedly installed on the top of the pin.

[0011] Optionally, a spring is movably sleeved on the outer surface of the pin, and the two ends of the spring are respectively fixedly connected to the pressure plate and the pull handle.

[0012] Optionally, the gasket is circular in shape, and the diameter of the gasket is the same as the diameter of the push rod.

[0013] 1. According to one embodiment of this disclosure, by setting a mold block, a push rod, a gasket, a crossbar and a drive assembly, when in use, after the operator positions the mold block on the base, liquid silicone can be directly poured into the mold cavity of the mold block for molding. After molding, the crossbar can be used to drive the push rod and the gasket to move upward through the drive assembly, thereby ejecting the molded climbing support. This not only facilitates demolding but also enables the climbing support to achieve a good molding effect.

[0014] 2. According to one embodiment of this disclosure, by setting a threaded rod, a pressure plate and a movable plate, after the worker places the mold block on the base, he can rotate the threaded rod to make the pressure plate move downward, which can clamp and fix the mold block, ensuring the stability of the mold block during subsequent demolding. If the width of the mold block is small, the movable plate can also be moved to adjust the distance between the two movable plates, so as to clamp mold blocks of different sizes and improve applicability.

[0015] 3. According to one embodiment of this disclosure, by setting a pin, a handle and a spring, after the operator adjusts the position of the movable plate, the pin can be inserted into the top groove at the corresponding position, thereby limiting the movable plate. Furthermore, due to the restoring effect of the spring, the handle and the pin will tend to move downwards, thereby further ensuring the limiting effect on the movable plate.

[0024] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0025] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0026] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0027] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0028] like Figures 1-5 As shown, a molding die for a sandstone-textured material surface includes a base 1, a mold block 2 movably mounted on the base 1, two push rods 3 movably inserted into the base 1, the tops of the two push rods 3 penetrating the mold block 2, a gasket 4 fixedly mounted on the tops of the two push rods 3, and two crossbars 5 fixedly connected between the bottoms of the two push rods 3. The crossbars 5 are connected to the base 1 through a drive assembly, which enables the crossbars 5 to drive the push rods 3 to move upward. A clamping assembly is also provided on the base 1 for clamping and limiting the mold block 2.

[0029] Sandblasting can be performed on the inner wall of the mold cavity of mold block 2 to form a uniform rough texture, so that the surface of the climbing support can form a sandstone texture after it is formed in mold block 2.

[0030] The above-mentioned molding die for a sandstone-like surface of a material has a driving component including a bidirectional lead screw 6, which is rotatably connected to a base 1. Both sides of the outer surface of the bidirectional lead screw 6 are threaded with sliders 7, and a connecting rod 8 is hinged between the sliders 7 and the crossbar 5.

[0031] By rotating the bidirectional lead screw 6, the two sliders 7 can move in opposite directions, which in turn drives the connecting rod 8 to move. This causes the connecting rod 8 to pull the crossbar 5, which in turn drives the ejector rod 3 and the washer 4 to move upward, thereby ejecting the rock climbing support point formed in the mold block 2 and achieving a rapid demolding effect.

[0032] The above-mentioned molding die for a sandstone-like surface of a material has a base 1 with a guide rail 9 fixedly installed at the bottom. The guide rail 9 is slidably connected to the slider 7, and the outer surface of the guide rail 9 is coated with a lubricating layer.

[0033] The design of guide rail 9 makes the slider 7 move more smoothly when moving left and right.

[0034] The above-mentioned molding die for a sandstone-like surface of a material has a clamping component including a square frame 10. There are two square frames 10, which are respectively fixedly installed on the two sides of the top of the base 1. A threaded rod 11 is rotatably connected to the square frame 10, and a pressure plate 12 is threaded onto the outer surface of the threaded rod 11.

[0035] After the staff places the mold block 2 on the base 1, they can rotate the threaded rod 11 to make the pressure plate 12 move downward, thereby clamping and fixing the mold block 2 on the base 1, thus ensuring the stability of the mold block 2 when the climbing support is demolded.

[0036] The above-mentioned molding die for a sandstone-like surface of a material has a square groove 13 on the pressure plate 12, a movable plate 14 that is slidably connected inside the square groove 13, and a top groove 15 on the top of the movable plate 14.

[0037] By moving the movable plate 14, the total length of the movable plate 14 and the pressure plate 12 can be adjusted, which facilitates the clamping of mold blocks 2 of different lengths and improves applicability.

[0038] The above-mentioned molding die for a sandstone-textured material surface has a pin 16 movably inserted into the pressure plate 12. The bottom of the pin 16 extends into the top groove 15, and a pull handle 17 is fixedly installed on the top of the pin 16.

[0039] After the staff moves the movable plate 14 to a suitable position as needed, the pin 16 can be inserted into the corresponding top groove 15 to limit the movable plate 14 and improve the stability of the movable plate 14 when clamping the mold block 2.

[0040] The above-mentioned molding die for a sandstone-textured material surface has a spring 18 movably sleeved on the outer surface of the pin 16, with the two ends of the spring 18 fixedly connected to the pressure plate 12 and the pull handle 17, respectively.

[0041] By setting the spring 18 to a stretched state, the spring 18's restoring force will cause the pull handle 17 and the pin 16 to tend to move downwards, thereby ensuring that the bottom of the pin 16 can be stably kept inside the top groove 15, thus further ensuring the limiting effect on the movable plate 14.

[0042] The above-mentioned molding die for a sandstone-textured material surface has a circular shim 4 with the same diameter as the push rod 3.

[0043] The pad 4 can be made of rubber. Due to the soft nature of rubber, it can provide good protection for the surface of the climbing hold when it is ejected after it has been formed.

[0044] Working principle and usage process of this utility model:

[0045] First, the worker places the mold block 2 on the base 1, so that the top rod 3 and the washer 4 pass through the hole at the bottom of the mold block 2. Then, the position of the movable plate 14 can be adjusted according to the width of the mold block 2. The movable plate 14 is then limited by the pin 16. Then, the threaded rod 11 can be rotated so that the pressure plate 12 drives the movable plate 14 to move downward to clamp and fix the mold block 2. Liquid silicone can then be poured into the mold cavity of the mold block 2. After solidification, the worker can rotate the double-acting screw 6 so that the two sliders 7 move in opposite directions along the surface of the guide rail 9. This allows the connecting rod 8 to drive the crossbar 5 to move, which in turn drives the top rod 3 and the washer 4 to move upward, thus ejecting the formed climbing support.

[0046] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
