Abstract
Description
Technical Field
[0001] This utility model relates to a modular building forming equipment, and more particularly to an inner mold demolding structure in a modular building forming equipment. Background Technology
[0002] Modular building molding equipment (commonly known as 3D vertical molding) consists of an outer mold and an inner mold. The inner mold comprises four corner molds, four inner side molds, and a top mold. To detach the component, the inner mold needs to be retracted. Manufacturers typically use a strip-shaped slide to facilitate demolding, confining the inner mold's movement within a downward-sloping slide. Lever structures on both sides at the bottom allow for movement. However, this method suffers from several drawbacks. When the inner mold detaches from the component, the demolding force is uneven, leading to poor stability of the inner side molds during operation and a tendency for deformation (resulting in decreased repositioning accuracy). This makes subsequent mold closing difficult, hindering the inner mold's repositioning and reducing the efficiency of demolding the component. Summary of the Invention
[0003] The purpose of this utility model is to provide an inner mold demolding structure in a modular building forming equipment. When the inner mold is separated from the component, each inner mold can remain stable during operation and is not easily deformed, thereby improving work efficiency. This solves the problem that when the inner mold is separated from the component, the demolding force is uneven from left to right and the deformation of the inner mold makes subsequent mold closing difficult.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A modular building forming equipment includes an inner mold demolding structure with a rectangular inner mold composed of four inner side molds, four corner molds (and a top mold). The inner mold contains a rectangular steel frame. The four inner side molds are designated as a left inner side mold, a right inner side mold, a front end mold, and a rear end mold. Each corner mold is located at the intersection of two adjacent inner side molds. The technical solution involves several first hydraulic cylinders and several first connecting rods between each inner side mold and one side of the corresponding steel frame. The bottom end of the cylinder of each first hydraulic cylinder is hinged to one side of the corresponding steel frame, and the top end of the piston rod of the first hydraulic cylinder is hinged to the inner wall of the corresponding inner side mold. The inner end of each first connecting rod is hinged to one side of the corresponding steel frame, and the outer end of the first connecting rod is hinged to the inner wall of the corresponding inner side mold.
[0005] Each of the aforementioned corner molds has several second hydraulic cylinders and several second connecting rods between one end corner of the corresponding steel frame. The bottom end of the cylinder of each second hydraulic cylinder is hinged to one end corner of the corresponding steel frame, and the top end of the piston rod of the second hydraulic cylinder is hinged to one of the corresponding corner molds. The inner end of each second connecting rod is hinged to one end corner of the corresponding steel frame, and the outer end of the second connecting rod is hinged to one of the corresponding corner molds.
[0006] In the above technical solution, a preferred technical solution may be that each inner mold and one side of the corresponding steel frame have two first hydraulic cylinders and four first connecting rods, that is, the number of first hydraulic cylinders is two and the number of first connecting rods is four. The two first hydraulic cylinders are arranged symmetrically from left to right, and the four first connecting rods are arranged symmetrically from top to bottom and from left to right when they are in a horizontal state.
[0007] In the above technical solution, a preferred embodiment may further include a second hydraulic cylinder and two second connecting rods between each corner mold and one end corner of the corresponding steel frame. Specifically, there is one second hydraulic cylinder and two second connecting rods. The bottom end of the cylinder of the second hydraulic cylinder is located at the hinge point where it is hinged to one end corner of the steel frame, at the upper-lower midpoint of that end corner. The two second connecting rods are arranged symmetrically vertically. When the inner mold is closed, each first connecting rod and each second connecting rod are in a horizontal state.
[0008] In this invention, each inner mold has several first hydraulic cylinders and several first connecting rods between it and one side of the corresponding steel frame; each corner mold has several second hydraulic cylinders and several second connecting rods between it and one end corner of the corresponding steel frame. Thus, the inner mold (including the corner mold) and the steel frame are connected by a connecting rod structure (the connecting rods include first and second connecting rods), ensuring that the inner mold (including the corner mold) remains stable during operation under the action of the cylinders (i.e., the first and second hydraulic cylinders). The inner mold is not easily deformed, and the stability and reset accuracy of the inner mold and corner mold during operation are good. Furthermore, in the mold-closed state, the connecting rods (including the first and second connecting rods) are in a horizontal, self-locking position, reducing the force on the cylinders (i.e., the first and second hydraulic cylinders) and greatly extending their service life. This invention utilizes the extension and retraction of a first and second hydraulic cylinder to move the inner mold, enabling the connecting rods (including the first and second connecting rods) to switch between horizontal and oblique movements. When the first and second connecting rods are horizontal, they form a self-locking mechanism, preventing the inner mold from moving. During demolding, the first and second hydraulic cylinders retract (i.e., the piston rods retract), causing the inner mold and corner molds to move inward and downward, thus separating the inner mold from the component. Conversely, during mold closing, the piston rods of the first and second hydraulic cylinders extend, causing the piston rods of the first and second hydraulic cylinders to move the inner mold and corner molds outward and upward, thus closing the inner mold. When the mold is closed, the first and second connecting rods are horizontal. As the cement solidifies, it expands, generating an inward force on the inner mold. This force is transmitted to the steel frame through the first and second connecting rods, respectively. The steel frame then exerts reaction forces on the first and second connecting rods, thus balancing the forces (canceling each other). If the first and second connecting rods are not horizontal when the mold is closed, a downward force will be generated, causing the inner mold to easily move downwards. Consequently, the thickness of the walls on both sides of a single component cannot be guaranteed to be consistent. Therefore, this invention ensures that the thickness of the walls on both sides of a single component is consistent.
[0009] In summary, this invention ensures stability of all inner molds and corner molds during operation when the inner mold separates from the component, preventing deformation of the inner mold and thus improving work efficiency. It also solves the problems of uneven demolding force and mold deformation making subsequent mold closing difficult when the inner mold separates from the component. Experiments show that compared to related technologies, the inner mold demolding structure of this invention improves the working efficiency of the molding die by more than 9%.
[0010] Furthermore, combined with the excellent rigidity of the inner mold, the inner mold demolding structure of this utility model eliminates the need for traditional through-wall nail structures, allowing the outer mold to be configured with a caisson structure, thus reducing the amount of concrete used and lowering production costs.

[0014] To make the invention's objectives, technical solutions, and advantages clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the following embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0015] Example 1: As Figure 1 , Figure 2 , Figure 3 As shown, the inner mold demolding structure of the modular building forming equipment of this utility model has a cuboid inner mold A, which is composed of four inner side molds 1, four corner molds 2 (and a top mold). The inner mold A has a cuboid steel frame 3. The four inner side molds 1 are divided into a left inner side mold, a right inner side mold, a front end mold, and a rear end mold. Each corner mold 2 is located at the intersection of two adjacent inner side molds. Each inner side mold 1 has several first hydraulic cylinders 4 and several first connecting rods 5 between it and one side of the corresponding steel frame 3. The bottom end of the cylinder of each first hydraulic cylinder 4 is hinged to one side of the corresponding steel frame 3, and the top end of the piston rod of the first hydraulic cylinder 4 is hinged to the inner wall of the corresponding inner side mold 1. The inner end of each first connecting rod 5 is hinged to one side of the corresponding steel frame 3, and the outer end of the first connecting rod 5 is hinged to the inner wall of the corresponding inner side mold 1.
[0016] Each of the corner molds 2 has several second hydraulic cylinders 7 and several second connecting rods 6 between one end corner of the corresponding steel frame 3. The bottom end of the cylinder of each second hydraulic cylinder 7 is hinged to one end corner of the corresponding steel frame 3, and the top end of the piston rod of the second hydraulic cylinder 7 is hinged to one of the corresponding corner molds 2. The inner end of each second connecting rod 6 is hinged to one end corner of the corresponding steel frame 3, and the outer end of the second connecting rod 6 is hinged to one of the corresponding corner molds 2.
[0017] Each inner mold 1 has two first hydraulic cylinders 4 and four first connecting rods 5 between one side of the corresponding steel frame 3. That is, there are two first hydraulic cylinders 4 and four first connecting rods 5. The two first hydraulic cylinders 4 are arranged symmetrically from left to right, and the four first connecting rods 5 are arranged symmetrically from top to bottom and from left to right when they are in a horizontal state.
[0018] Each corner mold 2 has a second hydraulic cylinder 7 and two second connecting rods 6 between one end corner of the corresponding steel frame 3. Specifically, there is one second hydraulic cylinder 7 and two second connecting rods 6. The bottom end of the cylinder of the second hydraulic cylinder 7 is located at the hinge point where it is hinged to one end corner of the steel frame 3, at the upper and lower midpoint of that end corner. The two second connecting rods 6 are arranged symmetrically vertically. When the inner mold 1 is closed, each first connecting rod 5 and each second connecting rod 6 is in a horizontal state.
[0019] In this invention, each inner mold 1 has several first hydraulic cylinders 4 and several first connecting rods 5 between it and one side of the corresponding steel frame 3; each corner mold 2 has several second hydraulic cylinders 7 and several second connecting rods 6 between it and one end corner of the corresponding steel frame 3. Thus, the inner mold (including the corner mold) and the steel frame 3 are connected by a connecting rod structure (the connecting rods include first connecting rods 5 and second connecting rods 6), ensuring that the inner mold (including the corner mold) remains stable during operation under the action of the cylinders (i.e., first hydraulic cylinders 4 and second hydraulic cylinders 7), and the inner mold does not... The mold is easily deformable, but exhibits good stability and high reset accuracy during operation of the inner molds and corner molds. Furthermore, in the mold-closed state, the connecting rods (including the first connecting rod 5 and the second connecting rod 6) are in a horizontal, self-locking position, reducing the force on the hydraulic cylinders (i.e., the first hydraulic cylinder 4 and the second hydraulic cylinder 7) and significantly extending their service life. This invention achieves the movement of the inner mold through the extension and retraction of the first hydraulic cylinder 4 and the second hydraulic cylinder 7, enabling the connecting rods (including the first connecting rod 5 and the second connecting rod 6) to switch between horizontal and oblique movements. When the first connecting rod 5 and the second connecting rod 6 are in a horizontal state, they form a self-locking mechanism, preventing the inner mold from moving. During demolding, the first hydraulic cylinder 4 and the second hydraulic cylinder 7 retract (i.e., the piston rod retracts), driving the inner mold 1 and the corner mold 2 to move inward and downward, completing the separation of the inner mold from the component. Conversely, during mold closing, the piston rods of the first hydraulic cylinder 4 and the second hydraulic cylinder 7 extend. The piston rod of the first hydraulic cylinder 4 drives the inner mold 1 and the piston rod of the second hydraulic cylinder 7 to move the corner mold 2 outward and upward, completing the inner mold closing. During mold closing, the first connecting rod 5 and the second connecting rod 6 are in a horizontal state. When the cement solidifies, it expands, generating an inward force on the inner mold. This force is transmitted to the steel frame 3 through the first connecting rod 5 and the second connecting rod 6 respectively. The steel frame 3 will generate reaction forces on the first connecting rod 5 and the second connecting rod 6 respectively, and the forces on both sides will reach a balance (cancel each other out). If the first connecting rod 5 and the second connecting rod 6 are not in a horizontal state during mold closing, a downward component force will be generated, and the inner mold 1 will easily move downward, and the thickness of the walls on both sides of the (single) component cannot be guaranteed to be consistent. Therefore, this utility model can ensure that the thickness of the walls on both sides of the (single) component is consistent.
[0020] In summary, this invention ensures stability of all inner molds and corner molds during operation when the inner mold separates from the component, preventing deformation of the inner mold and thus improving work efficiency. It also solves the problems of uneven demolding force and mold deformation making subsequent mold closing difficult when the inner mold separates from the component. Experiments show that compared to related technologies, the inner mold demolding structure of this invention improves the working efficiency of the molding die by more than 9%.
[0021] Furthermore, combined with the excellent rigidity of the inner mold, the inner mold demolding structure of this utility model eliminates the need for traditional through-wall nail structures, allowing the outer mold to be configured with a caisson structure, thus reducing the amount of concrete used and lowering production costs.
