Description

Technical Field

[0001] The present invention relates to the technical field of precast component equipment, and more particularly, to a mold device for concrete precast components with efficient demolding. Background Art

[0002] In the production process of existing concrete precast components, mold demolding is a key step, which directly affects production efficiency and the quality of precast components. Currently, most demolding devices use a method of driving the mold to rotate 180 degrees by a rotating motor for demolding operations. This traditional method drives the mold to rotate around a fixed axis through the motor to achieve the separation of the component from the mold. However, this method has obvious disadvantages.

[0003] Firstly, the method of driving the mold to rotate by a rotating motor often requires a large amount of electrical energy support. Especially when the mold is heavy, the power requirement of the rotating motor is large, resulting in significant energy consumption and low efficiency. Secondly, since the rotational movement of the mold generally needs to be supported by a hoisting system, strong structural support is required during operation. This not only increases the weight and floor area of the equipment, but also places high requirements on the stability of the hoisting equipment. More importantly, there is a certain inertia during the rotation of the mold, which may cause misalignment or damage to the precast component during demolding, thus affecting the quality of the component. Summary of the Invention

[0004] The purpose of the present invention is to provide a mold device for concrete precast components with efficient demolding, which aims to improve the demolding efficiency of concrete precast components by optimizing the demolding structure and significantly reduce energy consumption at the same time.

[0011] Furthermore, two ends of the pair of bottom plates which are away from each other are each provided with a convex edge, and the convex edge is used for abutting against an outer wall of the side shell.

[0012] Furthermore, it also includes a knocking component, which is arranged in a one-to-one correspondence with the first cylinder, and the knocking component includes a sliding rod, a knocking block, a return spring and a pulling piece. The sliding rod is slidably arranged on the bracket, and the knocking block is fixedly arranged at the end of the sliding rod. One end of the return spring is fixedly connected to the knocking block, and the other end is fixedly connected to the bracket. The pulling piece is used to release the sliding block after pulling the sliding block away from the side shell for a certain distance to knock the side shell.

[0013] Furthermore, the pulling member includes a hanging block and a hook, the hanging block is fixedly connected to the sliding rod, the hook is fixedly connected to the piston rod of the first cylinder, the hook body of the hook has a certain elasticity, the hook portion of the hook is used to hook with the hook, and the hanging block and the hook have a certain gap in their initial state, so that the hanging block and the hook can hook with each other after the piston rod of the first cylinder moves a certain distance.

[0014] Furthermore, a force-bearing block is fixedly provided at a position of the side shell corresponding to the striking block, a notch hole is opened on a side of the force-bearing block facing the side shell, and a rib plate is welded between the force-bearing block and the side shell.

[0015] Furthermore, a plug-in strip and a plug-in slot are respectively provided on the contact surfaces between the two bottom plates, and the plug-in strip and the plug-in slot are plugged and matched with each other.

[0016] Furthermore, it also includes a separation component, which includes a cam, a reset member and a swing member.

[0018] Furthermore, the bottom of the side shell is fixedly connected to the sliding column through an extension rod. Long strip grooves for sliding cooperation with the sliding column are correspondingly opened on both sides of the bracket near the lower position.

[0019] The technical solution of the present invention has at least the following advantages and beneficial effects:

[0020] 1. By the synergistic effect of the precast film shell, the bracket and the driving component, the present invention significantly improves the demoulding efficiency of concrete precast components and reduces energy consumption at the same time. During the demoulding process of traditional molds, due to the certain adhesive tension between the cement and the mold, the removal of the bottom plate usually cannot completely achieve the automatic falling off of the components, and often requires additional external force or complex operation steps. The present invention designs a combined demoulding method that can drive the bottom plate and the side shell in sequence, and by making full use of gravity and the structural design optimization of the mold, realizes the sequential actions of the bottom plate sliding first and then the side shell sliding.

[0021] Specifically, although the initial sliding of the bottom plate can effectively reduce the adhesion force, due to the viscosity between the cement and the mold, the component will not completely break away from the mold. After the bottom plate slides, the side shell further slides in the width direction. By cooperating with the bottom plate, it drives the concrete precast component to break away from the mold, and the precast component under the action of gravity will automatically separate from the mold, avoiding additional thrust or manual operation. This design not only reduces the demand for external power, thereby reducing energy consumption, but also makes the demoulding process more concise and efficient, reducing the complexity of manual intervention. Through this efficient demoulding structure, while ensuring the integrity of the component, it can improve production efficiency and equipment stability, reduce production interruptions caused by excessive disassembly or frequent maintenance, improve the service life of the mold and reduce the maintenance cost.

Detailed implementation manners

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents the selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0031] Embodiment

[0032] The following refers to Figures 1-6As shown below, in combination with specific embodiments, this embodiment provides a mold device for precast concrete components with efficient demolding, including a precast formwork shell 1. The precast formwork shell 1 has a structure that is larger at the top and smaller at the bottom. This device is also mainly aimed at such precast concrete guardrail pier components. The precast formwork shell 1 includes two side shells 11 on both sides and a pair of bottom plates 12 at the bottom. The two side shells 11 on both sides and the pair of bottom plates 12 at the bottom jointly enclose a space for pouring concrete. After the pair of bottom plates 12 at the bottom are removed, it is more difficult for the concrete precast component of this shape to directly fall off. The materials of the bottom plates 12 and the side shells 11 can be selected as steel plates or composite materials. According to different pouring requirements, the thickness and stiffness of the bottom plates 12 can be adjusted to ensure that they have sufficient supporting force during concrete pouring.

[0033] On both sides in the length direction of the bracket 2, there are spaces 21 for the removal of concrete precast components. The two side shells 11 on both sides and the pair of bottom plates 12 at the bottom are all slidably connected to the bracket 2 at the same time and can be synchronously separated or closed along the width direction of the bracket 2. The bracket 2 is made of strong metal materials such as steel or aluminum alloy, and its internal structure can also be increased with reinforcing rib plates 1112 to increase the compressive resistance and anti-deformation ability of the bracket 2, ensuring the stability of the equipment during long-term operation.

[0034] Referring to Figure 1 and Figure 2 As shown, the driving assembly 3 is the core part of the demolding process. The driving assembly 3 is used to sequentially drive a pair of bottom plates 12 to slide relative to each other along their sliding directions, and then drive the two side shells 11 to slide along the width direction of the bracket 2 to achieve demolding. The driving assemblies 3 are correspondingly located on both sides of the precast formwork shell 1. The two driving assemblies 3 are mainly composed of a first cylinder 31, a first folding rod 32, and a second folding rod 33. The cylinder block of the first cylinder 31 is fixed on the bracket 2, and the piston rod is fixedly connected to the bottom plate 12.

[0035] The driving assembly 3 controls the relative sliding of the bottom plates 12 and the side shells 11. Specifically, first, the bottom plates 12 are pulled to slide relative to each other along the sliding direction, and then the two side shells 11 are pulled to slide along the width direction of the bracket 2. To achieve this process, the first folding rod 32 and the second folding rod 33 are connected by a hinged structure. One end of the first folding rod 32 is hinged to the bottom plate 12, and the other end is hinged to the second folding rod 33. The other end of the second folding rod 33 is hinged and installed on the side shell 11. Through the drive of the cylinder, the angle change of the folding rod will sequentially move the bottom plate 12 and then drive the sliding of the side shell 11, thus completing the demolding. In particular, in other embodiments, the first cylinder 31 can also be replaced by an electric cylinder or a hydraulic cylinder to adapt to different power requirements and working conditions.

[0036] In order to further improve the stability of the side shells 11 on both sides, a convex edge 121 is designed at the contact position between the bottom plate 12 and the side shell 11. The convex edge 121 contacts the outer wall of the side shell 11, which can effectively improve the stability of the side shell 11 and prevent the side shell 11 from deforming irregularly due to excessive friction between the side shell 11 and the bottom plate 12 during demolding. The design of the convex edge 121 not only increases the contact area between the side shell 11 and the mold, but also reduces the concentrated distribution of friction, making the mold more stable during operation.

[0037] Reference Figure 2 and Figure 3 As shown, the knocking assembly 4 is used to assist in knocking the side shell 11 during the demolding process to help demolding. The main components of the knocking assembly 4 include a sliding rod 41, a knocking block 42, a reset spring 43 and a pulling member 44. The sliding rod 41 slides through a slide rail installed on the bracket 2, and the knocking block 42 is fixed to the end of the sliding rod 41 and connected to the bracket 2 through a reset spring 43. The function of the reset spring 43 is to ensure that the knocking block 42 can automatically return to the initial position after each knocking operation, and at the same time it serves the purpose of providing knocking force.

[0038] Reference Figure 3 As shown, the pulling member 44 includes a hanging block 441 and a hook 442. The hanging block 441 is firmly connected to one end of the sliding rod 41 by bolting or welding. The hook 442 is fixedly connected to the piston rod of the first cylinder 31.

[0039] The hook body of the hook 442 is made of elastic material, usually alloy steel or plastic composite material, which has certain elasticity and durability, so that it can maintain sufficient tensile resistance when subjected to tension, and avoid permanent deformation after long-term use. The hook portion of the hook 442 is designed to be hooked with the hook hole on the hanging block 441, ensuring that when the first cylinder 31 is driven, the hanging block 441 and the hook 442 can be reliably combined together, thereby jointly driving the sliding rod 41 to move.

[0040] The hook portion of the hook 442 is used to hook with the hook 443. The initial state of the hanging block 441 and the hook 442 has a certain gap, so that the hanging block 441 and the hook 442 are hooked with each other after the piston rod of the first cylinder 31 moves a certain distance, so that the hook 442 can hook and pull the sliding rod 41. After pulling a certain distance, since the hook body of the hook 442 has a certain elasticity, when the sliding rod 41 is under the action of the reset spring 43, the elastic force is too large, the hanging block 441 and the hook 442 will be separated, and then hit the side shell 11. In the process of the first cylinder 31 driving the bottom plate 12 to reset, since the upper end of the hook portion of the hook 442 has a certain arc surface, the hanging block 441 can push the hook 442 to reset, and be ready for the next demoulding operation.

[0041] Referring to Figure 4 and Figure 5 As shown, in order to improve the uniformity of the force between the striking block 42 and the side shell 11, the force receiving block 111 is welded at the contact position between the side shell 11 and the striking block 42, and a notch hole 1111 is provided on the side of the force receiving block 111 facing the side shell 11. The design of the notch hole 1111 helps to increase the force receiving area, thereby reducing the possible local stress concentration during demolding. The welding rib 1112 between the force receiving block 111 and the side shell 11 enhances the connection strength between the two, ensuring that the striking block 42 will not cause deformation or damage to the side shell 11 during operation.

[0042] Furthermore, insertion strips 122 and insertion grooves 123 are respectively provided on the mutually contacting surfaces between the two bottom plates 12. The cross-section of the insertion groove 123 is trapezoidal, and the insertion strips 122 and the insertion grooves 123 are inserted and matched with each other, thereby improving the stability between the two bottom plates 12.

[0043] Referring to Figure 2 As shown, the separation assembly 5 is another important part of the device. The separation assembly 5 includes a cam 51, a reset member 52, and a swing member 53. Slide columns 112 are fixedly welded on both sides in the length direction of the side shell 11. The slide columns 112 are square. In other embodiments, the slide columns 112 can be cylindrical. A long slot 22 that slidably cooperates with the slide columns 112 is provided on the bracket 2 in the width direction. The cam 51 is rotatably mounted at the middle position above the bracket 2 through a rotating shaft and bearings. The reset member 52 is used to drive the cam 51 to be in an initial state. In this embodiment, the reset member 52 is a coil spring 521. The coil spring 521 is sleeved on the rotating shaft of the cam 51, and the coil spring 521 is fixedly connected to the cam 51, and the other end is fixedly connected to the bracket 2. This initial state means that the two side shells 11 and the pair of bottom plates 12 at the bottom are in a closed state, and the slide columns 112 on the same side of the two side shells 11 are located on both sides in the radial direction of the cam 51. The swing member 53 is mounted on the bracket 2, and the swing member 53 is used to drive the cam 51 to push open the two slide columns 112 after the piston rod of the first cylinder 31 moves a certain distance.

[0044] Referring to Figure 1 and Figure 2As shown in the figure, the swinging member 53 includes a swinging wheel 531, a first swinging rod 532, a second swinging rod 533 and a linkage rod 534. The swinging wheel 531 is coaxially and fixedly installed on the cam 51. One end of the first swinging rod 532 is hinged on one side of the swinging wheel 531 deviating from the central axis. The other end of the first swinging rod 532 is hinged to the second swinging rod 533. The other end of the second swinging rod 533 is used to touch and connect with the linkage rod 534. The linkage rod 534 is fixedly connected to the output shaft of the first cylinder 31. The linkage rod 534 and the second swinging rod 533 are arranged at intervals. Among them, the second swinging rod 533 is hinged to the bracket 2 through a support shaft 23. The distance from the support shaft 23 to the connection of the first swinging rod 532 and the second swinging rod 533 is less than the distance from the support shaft 23 to the other end of the second swinging rod 533 itself. In this way, it can play a role in increasing the swing arm and saving effort. The swinging wheel 531 is connected to the output shaft of the first cylinder 31 through the linkage rod 534, and can drive the swinging member 53 to work under the action of the first cylinder 31, further pushing the cam 51 to push open the sliding column 112 to ensure that the two side shells 11 can be smoothly demolded.

[0045] Among them, in order to enhance the stability of the bracket 2 and improve the sliding performance, the bottom of the side shell 11 is fixedly connected to the sliding column 112 through an extension rod 113. The sliding column 112 and the bracket 2 are slidably matched through a long slot 22, so as to ensure that the side shell 11 can slide smoothly along the bracket 2 and avoid demolding failure caused by unstable sliding. Through reasonable structural design, not only enough space for the concrete precast member to move out is provided, but also the overall sliding strength and stability of the mold are improved.

[0046] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
