Description

Technical Field

[0001] This utility model belongs to the field of molds, specifically relating to an assembly-type prefabricated stair mold that is easy to assemble and disassemble. Background Technology

[0002] Prefabricated stair molds are mold-making equipment specifically designed for manufacturing prefabricated staircases. They typically consist of multiple modules, each corresponding to a part of the staircase, such as stair tread molds, stair handrail molds, and stair step molds.

[0003] According to the utility model patent with authorization announcement number CN114347227B, a prefabricated stair mold and a prefabricated stair production method are proposed. In view of the problem that it is often difficult to open the mold after the existing mold is completed, due to the heavy weight of the stair, the following solution is proposed: the stair mold includes a base, and a first support frame and a second support frame are fixedly installed on the top of the base respectively. The first support frame is located on the right side of the second support frame, and the same upper mold is fixedly connected to the first support frame and the second support frame.

[0004] Existing stair molds are mostly one-piece designs, which are large and inconvenient to transport and carry. Furthermore, the mold blanks are relatively uniform in style, making replacement difficult. Therefore, improvements are needed. Summary of the Invention

[0005] The purpose of this utility model is to provide an assembly-type prefabricated stair mold that is easy to assemble and disassemble, which solves the problem that existing stair molds are mostly one-piece, large in size, and inconvenient to transport and carry. At the same time, it also solves the problem that the mold blanks are relatively uniform in style and inconvenient to replace.

[0006] To achieve the above objectives, this utility model provides an easy-to-assemble and disassemble prefabricated stair mold, including a bottom template, four evenly distributed side templates placed on the top of the bottom template, with adjacent side templates in contact with each other, the top of the four side templates being slidably connected to a limit frame, locking rods being hinged to both the left and right sides of the bottom template, and a limit groove being fixedly connected to the side of the limit frame, with a non-standard nut being threaded to the upper end of the locking rod, and the non-standard nut contacting both the limit groove and the limit frame;

[0007] A mold blank is placed at the upper middle part of the bottom template. The mold blank is in contact with the side template. An installation block is fixedly connected to the bottom of the mold blank. The installation block penetrates the bottom template and is slidably connected to the bottom template.

[0008] The principle of this utility model is as follows: In use, first, place the mold blank on the upper end of the bottom template, and insert the mounting block at the bottom of the mold blank into the bottom template. Then, control the lever to insert the locking pin horizontally into the mounting block, thus completing the installation of the mold blank. Next, place each side template on the edge of the bottom template and position it using the positioning block. At this time, each side template surrounds the mold blank. Finally, after placing the limiting frame on the top of each side template, turn the locking rod by pulling the knob to make the locking rod slide into the limiting groove. Then, tighten the non-standard nut until it abuts against the limiting groove and the limiting frame, and the positioning bead on the non-standard nut also engages with the limiting frame. This completes the overall installation. Reverse the above steps to complete the overall assembly and disassembly, which is convenient for storage and carrying.

[0009] The beneficial effects of this utility model are as follows: by dividing the mold into a bottom template and a side template, the side template can be placed on the bottom template by a positioning block, and then a limiting frame is fitted on the top of each side template, and then the limiting frame is locked and installed. The mold as a whole is convenient to disassemble and easy to carry.

[0010] By setting an installation block at the bottom of the mold blank inside the mold, the installation block penetrates through the bottom template and protrudes below the bottom template. The bottom of the bottom template is equipped with a locking pin that extends laterally by a spring. The locking pin is inserted into the installation block under the action of the spring. In this way, the mold blank can be disassembled and assembled simply by controlling the relative engagement and disengagement between the locking pin and the installation block. The operation is simple and convenient.

[0011] Furthermore, a positioning block is fixedly connected to the bottom of the side template, and the positioning block engages with the bottom template. The positioning block serves to position the side template on the bottom template.

[0012] Furthermore, a pull button is fixedly connected to the top of the locking rod, and the pull button and the locking rod are an integral structure. The pull button facilitates the rotation of the locking rod.

[0013] Furthermore, a positioning bead is fixedly connected to the bottom of the non-standard nut, and the positioning bead engages with the limiting frame. The positioning bead prevents loosening of the non-standard nut.

[0014] Furthermore, a fixing sleeve is fixedly connected to the lower end of the bottom template, and a locking pin is slidably connected to the inner side of the fixing sleeve. The locking pin is inserted into the mounting block. A spring is provided on the inner side of the fixing sleeve, with one end of the spring fixedly connected to the locking pin and the other end fixedly connected to the inner surface of the fixing sleeve. The spring allows elastic force to be applied to the locking pin, causing it to insert into the mounting block.

[0015] Furthermore, a lever is fixedly connected to the end of the locking pin, and the lever passes through the fixing sleeve and is slidably connected to the fixing sleeve. The lever facilitates pulling down the locking pin.

[0016] Furthermore, support legs are welded to the four lower corners of the bottom template, and an adjusting rod is threadedly connected to the inner side of each support leg. A foot is fixedly connected to the bottom of the adjusting rod, and the foot contacts the support leg. The overall level can be adjusted by the relative threaded movement between the adjusting rod and the support leg. Attached Figure Description
