Description

Technical Field

[0001] The utility model relates to an assembled concrete frame mold, belonging to the technical field of molds. Background Technique

[0002] Concrete, abbreviated as "砼", refers to the general term for engineering composite materials in which aggregate is cemented into a whole by cementitious materials. It is widely used in civil engineering, and frame molds are required to limit the position of concrete during the concrete pouring process. For example, frame molds are needed during the pouring process of concrete precast slabs. During the process of precast slab pouring and forming of existing assembled concrete frames, the sizes of most frames are fixed structures.

[0003] Publication No.: CN220517110U mentions an assembled concrete frame mold. In this device, by rotating the crank handle, the positive and negative screw rods can be rotated. When the positive and negative screw rods rotate, the threaded connection blocks connected by positive and negative screw threads on both sides of their exterior will adjust the distance. During the process of the two threaded connection blocks adjusting the distance, they will drive the two diagonal rods to rotate crosswise. When the two diagonal rods rotate crosswise, the position of the left connection frame or the right connection frame can be adjusted. Therefore, users only need to rotate the two crank handles to adjust the distance between the left connection frame and the right connection frame so as to carry out concrete pouring and forming for precast slabs of different widths. However, this device can only adjust the size. After the precast slab is poured and formed, the poured and formed precast slab cannot be assisted to be pushed out of the frame mold and still needs to be slowly taken out manually, thus affecting the subsequent use efficiency. Now there is an urgent need for an assembled concrete frame mold to solve the above problems. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide an assembled concrete frame mold to solve the problems raised in the above background technique. The utility model designs an adjustable frame mold structure, which is convenient for pouring and forming precast slabs of different sizes and can quickly push out the poured and formed precast slabs from the frame mold.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated concrete frame mold, comprising a frame mold shell, a guide rod, a push clamp, and a conical connecting block. A servo motor is installed at the upper left end inside the frame mold shell, and a drive bevel gear is installed at the shaft end of the servo motor. Two bearing seats are longitudinally installed inside the frame mold shell, and a ball screw is installed through the two bearing seats. A screw nut is installed outside the ball screw. A casting groove is formed at the upper end of the frame mold shell, and a guide adjustment groove is formed on the right side of the upper end of the casting groove. The lower end of the guide rod passes through... The guide adjustment groove is connected to the lead screw nut. A bending plate is installed on the upper end of the guide rod. The push clamp is movable in the casting and forming groove, and the right end of the push clamp is fixed to the bending plate. Multiple fixed sliding cylinders are embedded in the left end of the casting and forming groove. Movable push rods are slidably installed in each of the multiple fixed sliding cylinders. Multiple tapered connecting blocks are provided. The multiple tapered connecting blocks are longitudinally located in the frame mold housing and are respectively fixed to the lower end of the multiple movable push rods. Multiple small electric push rods are installed at the lower end of the frame mold housing. The movable ends of the multiple small electric push rods pass through the lower end of the frame mold housing and are connected to the multiple tapered push blocks.

[0006] Furthermore, support blocks are installed on both the left and right sides of the lower end of the frame mold shell.

[0007] Furthermore, a driven bevel gear is longitudinally mounted on the left end of the ball screw, and the driven bevel gear meshes with the driving bevel gear for transmission.

[0008] Furthermore, a plurality of universal ball bearings are installed at the lower end of the bending plate, and the plurality of universal ball bearings slide on the upper side of the casting groove.

[0009] Furthermore, the upper ends of the plurality of conical push blocks respectively move against the plurality of conical connecting blocks.

[0010] Furthermore, all of the aforementioned small electric actuators are synchronously controlled by an external PLC controller.

[0011] The beneficial effects of this utility model are as follows: This utility model provides an assembled concrete frame mold. Because it incorporates a frame mold shell, servo motor, driving bevel gear, driven bevel gear, ball screw, screw nut, guide rod, bending plate, universal ball bearing, push clamp plate, small electric push rod, conical push block, conical connecting block, and movable push rod, our design improvements and practical use have shown that this device has a reasonable structure and good practicality. The adjustable frame mold structure facilitates the casting and molding of precast slabs of different sizes. It also allows for the rapid ejection of cast precast slabs from the frame mold, effectively reducing the time workers spend removing the precast slabs and thus improving the subsequent utilization efficiency of the precast slabs.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3This utility model provides a technical solution: an assembled concrete frame mold, including a frame mold shell 2, a guide rod 10, a push clamping plate 13, and a conical connecting block 17. A servo motor 3 is installed at the upper left end inside the frame mold shell 2, and a drive bevel gear 4 is installed at the shaft end of the servo motor 3. Two bearing seats 7 are longitudinally installed inside the frame mold shell 2, and a ball screw 6 is installed through the two bearing seats 7. A screw nut 8 is installed outside the ball screw 6. A casting and forming groove 14 is opened at the upper end of the frame mold shell 2, and a guide adjustment groove 9 is opened on the right side of the upper end of the casting and forming groove 14. The lower end of the guide rod 10 is connected to the screw nut 8 through the guide adjustment groove 9. A bending plate 11 is installed at the upper end of the guide rod 10. The push clamping plate 13 is movable within the casting and forming groove 14, and the push... The right end of the clamping plate 13 is fixed to the bending plate 11. Multiple fixed sliding cylinders 19 are embedded in the left end of the casting and forming groove 14. Movable push rods 18 are slidably installed in each of the multiple fixed sliding cylinders 19. Multiple tapered connecting blocks 17 are provided. The multiple tapered connecting blocks 17 are longitudinally located in the frame mold housing 2 and are respectively fixed to the lower end of the multiple movable push rods 18. Multiple small electric push rods 15 are installed at the lower end of the frame mold housing 2. The movable ends of the multiple small electric push rods 15 pass through the lower end of the frame mold housing 2 and are connected to the multiple tapered push blocks 16. This design solves the problem that the original device can only adjust the size. After the precast slab is poured and formed with concrete, it cannot be pushed out of the frame mold with assistance. It still needs to be slowly removed manually, which affects the efficiency of subsequent use.

[0019] As the first embodiment of this utility model: support blocks 1 are installed on both the left and right sides of the lower end of the frame mold housing 2. The added support blocks 1 can support the frame mold housing 2 and also facilitate the installation of multiple small electric push rods 15. A driven bevel gear 5 is longitudinally installed on the left end of the ball screw 6. The driven bevel gear 5 meshes with the driving bevel gear 4 for transmission. Through the added driven bevel gear 5 meshing with the driving bevel gear 4, the ball screw 6 can be driven to rotate when the servo motor 3 is working.

[0020] Multiple universal ball bearings 12 are installed at the lower end of the bending plate 11. These ball bearings 12 slide on the upper side of the casting groove 14. The addition of these ball bearings 12 facilitates the left-right movement of the bending plate 11 driven by the guide rod 10. Multiple small electric push rods 15 are synchronously controlled by an external PLC controller. The upper ends of multiple conical push blocks 16 respectively abut against multiple conical connecting blocks 17. By adding multiple conical push blocks 16 and their upper ends abutting against multiple conical connecting blocks 17, when the multiple conical push blocks 16 are moved upward by the multiple small electric push rods 15, they can push the multiple conical connecting blocks 17 upward.

[0021] As a second embodiment of this utility model: First, the servo motor 3 is started. The servo motor 3 drives the active bevel gear 4 to rotate, and the driven bevel gear 5 will mesh with it and rotate, thereby driving the ball screw 6 to rotate in place. Since the guide rod 10 is limited at the guide adjustment groove 9, the rotation of the ball screw 6 will drive the screw nut 8 to move to the left, so that the guide rod 10 can only be adjusted to move to the left at the guide adjustment groove 9. This can drive the bending plate 11, the push clamp plate 13 and multiple universal balls 12 to move to the left. The push clamp plate 13 can adjust the size of the casting molding groove 14 by moving to the left in the casting molding groove 14. After the adjustment is completed, the concrete can be poured into the casting molding groove 14. When the precast slab is cast, multiple small electric push rods 15 are started through the external PLC controller. The moving ends of the multiple small electric push rods 15 will drive multiple conical push blocks 16 to move upward. Because the arc surfaces of multiple conical push blocks 16 abut against the arc surfaces of multiple conical connecting blocks 17, when multiple conical push blocks 16 push multiple conical connecting blocks 17 upward, the arc surfaces of multiple conical push blocks 16 and multiple conical connecting blocks 17 are first brought into contact. During this process, multiple conical connecting blocks 17 and multiple movable push rods 18 will rotate slightly, causing the fixed connection between the upper end of multiple movable push rods 18 and the cast precast slab to break, and they will only move and touch. Then, multiple movable push rods 18 can move upward to push the cast precast slab out of the casting groove 14.
