Description

Technical Field

[0001] The utility model belongs to the technical field of mold frame production, and specifically relates to an automatic hoisting mechanism for mold frame production. Background Art

[0002] Formwork production refers to the process of manufacturing products or components used to shape and fix materials. Formwork is commonly used in various industrial production activities, especially in the fields of plastic injection molding, metal casting, concrete pouring, composite molding, etc.

[0003] In the current mold frame production process, the use of lifting mechanisms is an indispensable link. However, existing lifting mechanisms generally have certain operational limitations. Specifically, when performing lifting tasks, these lifting mechanisms usually need to rely on manual labor to fix the mold frame at its lower end. This manual method of fixing the mold frame not only consumes a lot of time and labor, but also may cause unstable fixation or low efficiency due to human factors during operation, thus affecting the smoothness and safety of the entire production process. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide an automated hoisting mechanism for mold frame production to solve the problem that the hoisting mechanism proposed in the above background technology usually needs to manually fix the mold frame at its lower end when performing the hoisting task. This manual method of fixing the mold frame not only consumes a lot of time and labor, but also may cause unstable fixation or low efficiency due to human factors during the operation, thereby affecting the smoothness and safety of the entire production process.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automated lifting mechanism for mold frame production, comprising a lifting plate and a top frame, a sliding groove is provided on the lower surface of the lifting plate, a sliding rod is fixedly connected to the inside of the sliding groove, a sliding plate is slidably connected to the surface of the sliding rod, a second spring structure is provided between the outer side of the sliding plate and the inner wall of the sliding groove, two sliding plates are provided, a first spring structure is provided between the two sliding plates, the lower ends of the inner parts of the two sliding plates are slidably connected to telescopic plates, the lower ends of the telescopic plates are fixedly connected to a stopper, the stopper is a right-angled triangle structure, slots are provided on both side surfaces of the top frame, and the top frame is fixedly installed on the upper end of the mold frame.

[0006] Preferably, a metal hook is fixedly connected to the upper surface of the hanging plate, and a plurality of the metal hooks are provided.

[0007] Preferably, inner surfaces of the sliding plate and the telescopic plate are both provided with grooves, and a plurality of grooves are provided.

[0008] Preferably, the inner walls of the sliding plate and the telescopic plate are provided with a frosted layer.

[0010] Preferably, the internal thread of the positioning hole is connected with a positioning bolt.

[0011] Preferably, the first spring structure and the second spring structure are both arranged on the surface of the sliding rod.

[0012] Compared with the prior art, the utility model provides an automatic hoisting mechanism for mold frame production, which has the following beneficial effects:

[0013] 1. The utility model fixes the top frame on the upper end of the mold frame during mold frame production by setting blocks and slots. When the mold frame needs to be automatically hoisted, the hoisting plate is moved to the upper end of the mold frame by the hoisting machine, and then the hoisting plate is slowly lowered. The slope of the lower surface of the block contacts the upper sides of the top frame, and then the block is squeezed to both ends. At this time, the first spring structure is in a stretched state, and the second spring structure is in an squeezed state. When the block reaches the position of the slot, due to the reset elastic force of the first spring structure and the second spring structure, the sliding plate and the telescopic plate at the lower end are squeezed toward the middle, and the mold frame is automatically lifted through the engagement connection between the upper surface of the block and the upper end of the slot of the top frame, effectively avoiding the need for the hoisting mechanism to manually fix the mold frame at its lower end when performing the hoisting task. This method of manually fixing the mold frame not only consumes a lot of time and labor, but also may cause unstable fixation or low efficiency due to human factors during operation, thereby affecting the smoothness and safety of the entire production process;

[0014] 2. The utility model increases the friction between the telescopic plate and the outer wall of the top frame by providing grooves, a plurality of grooves and frosted layers provided on the inner walls of the sliding plate and the telescopic plate, thereby effectively preventing the top frame and the mold frame from sliding during the hoisting process;

[0015] 3. The utility model provides structures such as telescopic plates, positioning holes and positioning bolts, and can adjust the length between the telescopic plates and the sliding plates according to the sizes of the top frame and the formwork before lifting, thereby achieving the purpose of lifting top frames and formworks of different sizes.

The mold frame is fixedly installed at the upper end of the mold frame. When the mold frame needs to be automatically hoisted, the hoisting plate 1 is moved to the upper end of the mold frame by the hoisting machine, and then the hoisting plate 1 is slowly lowered. The slope of the lower surface of the block 11 contacts the upper sides of the top frame 13, and then the block 11 is squeezed to both ends. At this time, the first spring structure 5 is in a stretched state, and the second spring structure 6 is in an squeezed state. When the block 11 reaches the position of the slot 14, due to the reset elastic force of the first spring structure 5 and the second spring structure 6, the sliding plate 7 and the telescopic plate 8 at the lower end are squeezed toward the middle, and the mold frame is automatically lifted through the engagement connection between the upper surface of the block 11 and the upper end of the slot 14 of the top frame 13, which effectively avoids the need for the hoisting mechanism to manually fix the mold frame at its lower end when performing the hoisting task. This manual method of fixing the mold frame not only consumes a lot of time and labor, but also may cause unstable fixation or low efficiency due to human factors during operation, thereby affecting the smoothness and safety of the entire production process.

[0025] In the utility model, preferably, the upper surface of the hanging plate 1 is fixedly connected with a metal hook 2, and a plurality of metal hooks 2 are provided.

[0026] In the present invention, preferably, the inner surfaces of the sliding plate 7 and the telescopic plate 8 are both provided with grooves 12 , and a plurality of grooves 12 are provided.

[0027] In the utility model, preferably, the inner walls of the sliding plate 7 and the telescopic plate 8 are provided with a frosted layer. Through the grooves 12, the frosted layers provided on the inner walls of the sliding plate 7 and the telescopic plate 8, the friction between the telescopic plate 8 and the outer wall of the top frame 13 is increased, thereby effectively preventing the top frame 13 and the formwork from sliding during the lifting process.

[0028] In the present invention, preferably, positioning holes 9 are provided on the surfaces of the sliding plate 7 and the telescopic plate 8 .

[0029] In the utility model, preferably, the internal thread of the positioning hole 9 is connected with a positioning bolt 10. By setting the telescopic plate 8, the positioning hole 9 and the positioning bolt 10 and other structures, the length between the telescopic plate 8 and the sliding plate 7 can be adjusted according to the size of the top frame 13 and the formwork before lifting, thereby achieving the purpose of lifting top frames 13 and formworks of different sizes.

[0030] In the present invention, preferably, the first spring structure 5 and the second spring structure 6 are both arranged on the surface of the sliding rod 4 .

[0031] The working principle and use process of the utility model: When using the automatic lifting mechanism for mold frame production, first adjust the length between the telescopic plate 8 and the sliding plate 7 through the positioning bolts 10 according to the size of the mold frame and the top frame 13 to ensure the hoisting adaptation. Then, start the hoisting machine, move the hoisting plate 1 to the position of the upper end of the mold frame top frame 13, and slowly lower the hoisting plate 1 so that the slope of the lower surface of the block 11 contacts the upper sides of the top frame 13. As the hoisting plate 1 continues to descend, the block 11 is squeezed toward both ends, the first spring structure 5 is stretched, and the second spring structure 6 is squeezed. When the block 11 reaches the position of the slot 14 on both sides of the top frame 13, the restoring elastic force of the spring structure squeezes the sliding plate 7 and the telescopic plate 8 toward the middle, and the mold frame is automatically fixed through the engagement connection between the upper surface of the block 11 and the upper end of the slot 14. At this time, the hoisting machine can continue to lift to realize the automatic lifting of the mold frame. During the hoisting process, the grooves 12 and the frosted layer on the inner side of the sliding plate 7 and the telescopic plate 8 increase the friction with the outer wall of the top frame 13 to prevent sliding and ensure safe and stable hoisting. After completing the hoisting task, the hoisting machine places the formwork at the designated position, and finally releases the block 11, and the spring structure is reset to prepare for the next hoisting.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
