Description

Technical Field

[0001] The utility model belongs to the field of concrete slab production equipment, and more specifically relates to a mold vehicle opening and closing equipment. Background Art

[0002] At present, in the autoclaved aerated concrete block or board production industry, the slurry is poured into a pre-made mold, and the green body is formed after the slurry is gasified and stabilized, and then the subsequent processing is carried out. Since the cavity length of the conventional mold is fixed and cannot be adjusted, only green bodies of a single length can be cast. However, in order to meet customer demand for boards of different lengths, it is often necessary to produce boards of different lengths, which requires the green body to be cut. In the existing process, the cut part of the green body is generally used to prepare blocks or to be crushed and recycled. However, whether it is blocks or crushing and recycling, it will increase production energy consumption and emissions, increase production costs, and the recycling process is also prone to waste of materials. In response to this problem, some solutions have also appeared on the market.

[0003] For example, the Chinese patent application number is CN202120593172.X, and the patent document with the publication date of November 12, 2021 discloses a partition of an autoclaved aerated concrete mold vehicle, including a baffle panel and a fixing frame, the fixing frame includes a left column and a right column, the left column and the right column are connected by a transverse telescopic mechanism, and the tops of the left column and the right column are provided with vertically installed clamping bolts, the two clamping bolts are located on one side of the plane where the fixing frame is located, the baffle panel is arranged below the clamping bolts, the baffle panel is parallel to the plane where the fixing frame is located, and the baffle panel can be pushed downward by rotating the clamping bolts. The utility model divides the mold cavity of the mold vehicle into two parts, and a part of the mold cavity can be poured separately during pouring.

[0004] Another example is a Chinese patent application number CN201911131000.4 filed by the applicant, published on February 4, 2020, which discloses a mold baffle, a mold baffle transfer device, and a method of using the same. The mold baffle includes a baffle frame, the rear side of the baffle frame is connected to the baffle body, the upper frame of the baffle frame is connected to a pair of hangers, and the front side of the baffle frame is connected to an expansion component and an adsorption component; the mold baffle transfer device includes a walking frame, a horizontal moving frame, a lifting component, a hanging component, and an assembly and disassembly component, and the method of use includes an installation method and a disassembly method. The invention uses its method of use to match the mold baffle with the mold baffle transfer device, and can cast blanks of different lengths as needed.

[0005] In the above two solutions, in order to solve the problem that the length of the mold cavity of the existing mold cart is difficult to adjust, a baffle is set to divide the mold cavity into two parts. However, in the two solutions, since the structure of the mold cart itself is a rectangular groove structure formed by a fixed bottom plate and four side plates to form a mold cavity, the baffle needs to be placed into the mold cavity of the mold cart from the top of the mold cart. In order to ensure that the baffle can smoothly divide the mold cavity, the size of the baffle must be slightly smaller than the size of the mold cavity. This leads to inaccurate control of the transfer equipment, or when the equipment is deformed and worn during long-term use, it is difficult to ensure that the baffle can be stably and smoothly placed in the mold cavity, thereby affecting the overall production of concrete. Summary of the invention

Therefore, the scope of the present invention is limited only by the appended claims.

[0036] Example 1

[0037] A mold car opening and closing device is used to cut the mold cavity of the mold car when placing a baffle plate, so that the baffle plate can be stably and smoothly placed in the mold cavity when adjusting the pouring length of the concrete slab. Its specific structure and technical effects are described in detail below.

[0038] like Figure 1 and Figure 2 As shown, the device mainly includes a mold vehicle body 1 and an opening and closing device 2.

[0039] The mold vehicle body 1 includes a bottom plate and three fixed side plates 11 and a flip side plate 12 arranged on the bottom plate. The flip side plate 12 is generally a side plate with a longer length, and the bottom of the flip side plate 12 is hingedly connected to the bottom plate. A locking pin 121 is arranged on the upper side of the end of the flip side plate 12 close to the fixed side plate 11, and a hook 111 for clamping the locking pin 121 is hingedly installed on the fixed side plate 11 adjacent to the flip side plate 12, and the hook 111 can rotate along the hinge point between it and the fixed side plate 11. The opening and closing device 2 is used to control the rotation of the flip side plate 12 and open the hook 111.

[0040] Under the above structure, the opening and closing device 2 can control the rotation of the flip side plate 12 to open the mold cavity of the mold vehicle body 1 from the side, so that the baffle can be easily and quickly placed in the mold cavity of the mold vehicle body 1 and fit the inner wall of the mold cavity, and then the flip side plate 12 is reset by the opening and closing device 2 and fixed by the locking pin 121 and the hook 111 to complete the installation of the baffle in the mold cavity. This method solves the problem that the control of the transfer device is not accurate enough and the baffle is difficult to accurately put into the mold cavity of the mold vehicle when the equipment is deformed and worn, and improves the production efficiency of concrete slabs.

[0041] In this embodiment, the end face 112 of the hook 111 close to the locking pin 121 is an inclined surface, and its lower side has a slot 113 that cooperates with the locking pin 121. When the flip side panel 12 is rotated and reset, the locking pin 121 can lift the hook 111 along the inclined surface and enter the slot 113 of the hook 111, thereby automatically resetting and fixing the flip side panel 12.

[0042] Meanwhile, a return spring 114 is also mounted on the fixed side plate 11, and the two ends of the return spring 114 are respectively fixedly connected to the fixed side plate 11 and the hook 111. Through the return spring 114, on the one hand, the position of the hook 111 can be fixed with a certain strength, and on the other hand, after the hook 111 is lifted up, the hook 111 can automatically return to its original position under the action of the return spring 114 to lock the lock pin 121, thereby achieving the fixation of the flip side plate 12.

[0043] The opening and closing device 2 only needs to ensure that the flip side plate 12 and the hook 111 can be controlled, and the structure of the opening and closing device 2 in this embodiment is as follows.

[0044] like Figure 1 As shown, there are multiple opening and closing devices 2. When the mold vehicle body 1 is in operation, it moves to the mold opening and closing position. At this time, an opening and closing device 2 is respectively provided at both ends of the flip side plate 12, and at least one opening and closing device 2 is also provided in the middle of the flip side plate 12. The opening and closing devices 2 at the ends of the flip side plate 12 not only realize the rotation of the flip side plate 12, but also cooperate with the hook 111, while the opening and closing device 2 at the middle of the flip side plate 12 is mainly to ensure the stability of the flip side plate 12 when it rotates. Therefore, the main structures of the two opening and closing devices 2 are basically the same, and there are only some differences in the structure.

[0045] Specifically, Figure 3 and Figure 4 As shown, the opening and closing device 2 includes a base 21, a rotating bracket 22, a bracket driving mechanism 23 and a lifting mechanism 24. Among them, one end of the rotating bracket 22 is hingedly connected to the base 21, the bracket driving mechanism 23 controls the rotating bracket 22 to rotate along the hinge point between it and the base 21, and the lifting mechanism 24 is installed on the rotating bracket 22.

[0046] During operation, the mold vehicle body 1 moves to the mold opening position, at which time, the flip side plate 12 is in a closed state, and the locking pin 121 is located in the card slot 113. The bracket driving mechanism 23 controls the rotating bracket 22 to rotate to a vertical state, and then the lifting mechanism 24 works to lift the hook 111, so that the hook 111 is separated from the locking pin 121, and the flip side plate 12 is supported by the rotating bracket 22. Then, the bracket driving mechanism 23 controls the rotating bracket 22 to rotate, so that the flip side plate 12 is opened, and the baffle is placed in the mold cavity.

[0047] After the baffle is placed, the bracket driving mechanism 23 controls the rotating bracket 22 to reset. At this time, the hook 111 is lifted up by the locking pin 121 along its inclined surface, so that the locking pin 121 enters the slot 113. At the same time, the hook 111 is reset under the elastic force of the reset spring 114, so that the locking pin 121 and the hook 111 are locked, and the flip side plate 12 is fixed to complete the placement of the baffle.

[0048] In this embodiment, in order to better support the flip side plate 12, a support roller 25 is installed at the position where the rotating bracket 22 contacts the flip side plate 12, which can reduce the friction generated when the flip side plate 12 is pushed up and improve the service life of the equipment. In order to ensure the precise lifting direction of the lifting mechanism 24, a guide rail 26 is provided on the rotating bracket 22, and a slider 27 that cooperates with the guide rail 26 is provided on the telescopic component of the lifting mechanism 24.

[0049] like Figure 3As shown, a lifting roller 28 is installed on the slider 27 of the opening and closing device 2 at the end of the flip side plate 12, so as to reduce the friction force when lifting the hook 111 and improve the service life.

[0050] And as Figure 4 As shown, a hook 29 is installed on the slider 27 of the opening and closing device 2 located in the middle of the flip side panel 12, so that when the flip side panel 12 is opened, the upper end of the flip side panel 12 can be clamped by the hook 29, and the rotating bracket 22 drives the flip side panel 12 to rotate through the hook 29. After the flip side panel 12 rotates to a certain angle, it can continue to rotate by its own gravity, thereby improving the working stability of the equipment. This is also the structural difference between the two opening and closing devices 2 at different positions.

[0051] In the opening and closing device 2, the lifting mechanism 24 is any one of a gas cylinder, a hydraulic cylinder and an electric push rod, and in this embodiment, it is a gas cylinder. The support driving mechanism 23 is any one of a gas cylinder, a hydraulic cylinder and an electric push rod, and in this embodiment, it is also a gas cylinder, one end of which is hingedly connected to the rotating support 22, and the other end is hingedly connected to the base 21.

[0052] In summary, a mold car opening and closing device in this embodiment can solve the problem that the transfer device is not accurately controlled and the baffle is difficult to accurately place into the mold cavity of the mold car when the equipment is deformed and worn, thereby improving the production efficiency of concrete slabs.
