Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a demolding and anti-sticking structure for building molds. Background Technology

[0002] Construction molds are temporary structures used for shaping concrete components. Their background technology can be traced back to ancient wooden formwork. Modern mold technology achieved a qualitative leap with the advent of steel, aluminum, and composite materials in the 20th century. Its development has progressed from handmade wooden molds to standardized steel molds, and then to adjustable modular and digital intelligent molds. Currently, they are widely used in cast-in-place concrete structures such as residences, bridges, and tunnels, as well as prefabricated buildings and municipal engineering projects. Their high precision and rapid turnaround characteristics improve construction efficiency and reduce costs. Especially in emerging 3D printed architecture, flexible mold technology further expands the boundaries of complex shapes.

[0003] In existing technologies, traditional building mold demolding mainly relies on manual hammering, application of release agent, or simple ejection mechanisms. This has problems such as low demolding efficiency, easy damage to concrete surface, and mold sticking leading to component defects. Especially when demolding complex structures or large-sized precast components, there is a lot of manual intervention and it is difficult to ensure consistency. Therefore, a building mold demolding anti-sticking structure has emerged. Utility Model Content

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example

[0025] Reference Figures 1-4 This is an embodiment of the present invention, which provides a demolding and anti-sticking structure for building molds, comprising:

[0026] The base plate 101, the mounting bracket 102 fixedly connected to the side wall of the base plate 101, the limiting post 103 fixedly connected to the side wall of the mounting bracket 102, the transmission assembly 104 disposed on the side wall of the mounting bracket 102, the ejection assembly 105 disposed on the surface of the transmission assembly 104, and the top mold assembly 106 movably connected to the surface of the ejection assembly 105.

[0027] The transmission assembly 104 includes a support frame 104a fixedly connected to the side wall of the base plate 101, and a jacking cylinder 104b adapted to be installed on the side wall of the support frame 104a. The transmission assembly 104 also includes a rack 104c fixedly connected to the end of the jacking cylinder 104b, and a transmission gear 104d meshing on the surface of the rack 104c.

[0028] Specifically, the transmission gear 104d is connected to the side wall of the base plate 101 via a bearing. The jacking cylinder 104b ensures that during operation, it can drive the rack 104c to rotate, thereby driving the transmission gear 104d to rotate, ensuring the convenient operation of the transmission gear 104d.

[0029] Furthermore, the ejection assembly 105 includes a mounting shell 105a sleeved on the surface of the limiting post 103, a transmission rod 105b rotatably connected to the inner wall of the mounting shell 105a, and a linkage gear 105c fixedly connected to the end of the transmission rod 105b. The ejection assembly 105 also includes a toothed screw 105d meshing with the surface of the linkage gear 105c, a threaded sleeve 105e threadedly connected to the surface of the toothed screw 105d, and a compression spring 105f fixedly connected to the inner wall of the mounting shell 105a.

[0030] The toothed lead screw 105d is designed to ensure that when the transmission rod 105b drives the linkage gear 105c to rotate, the linkage gear 105c can drive the toothed lead screw 105d to rotate, and the toothed lead screw 105d can drive the threaded sleeve to move up and down, ensuring that the threaded sleeve can push out the molded module and prevent sticking during demolding.

[0031] Preferably, the top mold assembly 106 includes a connecting shell 106a movably connected to the side wall of the mounting shell 105a, and a support rod 106b fixedly connected to the side wall of the connecting shell 106a. The top mold assembly 106 also includes a connecting block 106c inserted into the side wall of the connecting shell 106a, and an abutment 106d threadedly connected to the side wall of the connecting block 106c.

[0032] It should be noted that the design of the connecting shell 106a ensures quick connection to the machine, or that the connecting shell 106a can be pressed down with a heavy object to ensure the molding of the module. At the same time, the threaded abutment block 106d can be quickly replaced, ensuring smooth change when changing different molds.

[0033] In use, place the molded mold on a horizontal surface, remove the connecting shell 106a, and start the jacking cylinder 104b. The jacking cylinder 104b drives the rack 104c to reciprocate. The rack 104c drives the transmission gear 104d to rotate. The transmission gear 104d drives the transmission rod 105b to rotate. The transmission rod 105b drives the linkage gear 105c to rotate. The linkage gear 105c drives the toothed screw 105d to rotate. The screw rotates, which in turn drives the threaded sleeve 105. When the threaded sleeve 105e moves upward, it pushes out the model. After the model is pushed out, the jacking cylinder 104b retracts, driving the rack 104c to move in the direction of the jacking cylinder 104b. The transmission gear 104d, the transmission rod 105b and the linkage gear 105c rotate in opposite directions, thereby controlling the toothed screw to rotate in opposite directions, driving the threaded sleeve 105e to move downward, moving beyond the connecting shell 106a, thereby preventing the threaded sleeve 105e from sticking to the model.

[0034] In summary, the reciprocating motion of the rack 104c driven by the jacking cylinder 104b drives the transmission gear 104d, the linkage gear 105c, and the toothed screw 105d to rotate in unison, enabling the threaded sleeve 105e to achieve precise vertical displacement. This effectively ejects the molding module from the mold. Simultaneously, the retraction of the cylinder causes the threaded sleeve 105e to quickly return to its original position below the connecting shell 106a, completely avoiding the problem of mold and component adhesion during demolding. The modular design of the connecting shell 106a and the replaceable threaded abutment 106d further adapts to different mold requirements, ensuring both demolding efficiency and molding quality while simplifying the mold replacement process. Through the combined use of mechanical transmission and elastic elements, demolding stability is ensured while significantly improving operational convenience and equipment versatility.
