Abstract
Description
Technical Field
[0001] This utility model relates to the field of cement molding mold technology, specifically to an opening and closing structure of a cement precast foundation component production mold. Background Technology
[0002] Traditional molds for producing precast concrete foundation components mostly employ fixed or simple flip-type structures, with mold opening and demolding achieved through manual operation or simple mechanical devices. While these molds can meet basic molding requirements during production, they present numerous problems in the demolding process.
[0003] For example, cement parts are prone to sticking to the mold base, often requiring manual tapping or external tools for demolding. Furthermore, the lack of effective measures to secure the mold and cement parts during demolding means that when the mold is flipped, the cement parts are prone to shifting and tipping due to instability or vibration, leading to demolding failure or product deformation. Utility Model Content
[0004] To address the aforementioned problems, this utility model proposes an opening and closing structure for a precast concrete foundation component production mold, comprising a mold base with a top opening, a base being provided below the mold base, two mounting brackets being longitudinally arranged at both ends of the base, and a rotating shaft being fixed to the two opposite side walls of the mold base, with both ends of the rotating shaft being rotatably connected to the mounting brackets; a linear actuator mounted on the base is provided below the mold base, a connecting seat is fixed to the telescopic end of the linear actuator, a U-shaped frame is fixed above the connecting seat, a contact platform is placed on the top of the U-shaped frame, a vibration motor is installed inside the U-shaped platform, and the output end of the vibration motor contacts the bottom of the contact platform.
[0005] Furthermore, a servo motor is mounted on the side wall of one of the mounting brackets. The output end of the servo motor is connected to a drive shaft. A driven shaft is fixed to the end of the shaft near the servo motor. Spur gears are fixed to the outer surfaces of both the drive shaft and the driven shaft, and the two spur gears mesh with each other.
[0006] Furthermore, it also includes a cover plate that can be placed on a mold base. Connecting blocks are fixed at both ends of the bottom of the cover plate. When the cover plate is placed on top of the mold base, the connecting blocks are outside the mold base. A through hole is opened through the side wall of the connecting block, and an insertion hole is opened on the side wall of the mold base. An insertion rod is provided that can be inserted into the through hole and the insertion hole to connect the connecting block and the mold base.
[0007] Furthermore, the outer wall of the connector is provided with a storage slot for inserting the cover plate, and the outer wall of the connector is also provided with a storage hole for inserting the rod. When the cover plate and the rod are not needed, the cover plate and the rod are placed in the storage slot and the storage hole respectively.
[0008] Furthermore, both rotating shafts pass through adjacent mounting brackets, and limit rings are fixed on the outer sides of the rotating shafts on both sides of the mounting brackets. The limit rings are in contact with the mounting brackets and are rotatably connected.
[0009] The beneficial effects of this utility model are as follows:
[0010] 1. By using a cover plate and insert rod to firmly fix the cement part in the mold base before demolding, and with the 180-degree rotation of the mold base, the high-frequency vibration generated by the vibration motor is transmitted to the cement part through the contact table and cover plate, which effectively breaks the adhesion between the cement part and the inner wall of the mold, so that the cement part naturally detaches from the mold under the action of gravity, without the need for manual knocking or prying.
[0011] 2. During the demolding process, the fixing effect of the cover plate and the insert rod effectively prevents the cement parts from shifting and tipping. Especially during the mold flipping and vibration, it ensures the stability of the cement parts and can complete the demolding in a fixed state, effectively avoiding demolding failure or product deformation caused by the displacement and tipping of cement parts.

[0017] The present invention will be further described below with reference to the accompanying drawings:
[0018] An opening and closing structure for a precast concrete foundation component production mold, such as Figure 1 and Figure 2 As shown, the mold base 1 includes a top opening, a base 2 is provided below the mold base 1, and two mounting brackets 3 are longitudinally arranged at both ends of the base 2. Rotary shafts 4 are fixed to the two opposite side walls of the mold base 1, and both ends of the rotating shafts 4 are rotatably connected to the mounting brackets 3. Both rotating shafts 4 pass through adjacent mounting brackets 3. Limiting rings 16 are fixed to the outer surfaces of the rotating shafts 4 on both sides of the mounting brackets 3, and the limiting rings 16 are in contact with and rotatably connected to the mounting brackets 3. A linear actuator 5 is mounted on the base 2 below the mold base 1, and the telescopic end of the linear actuator 5... A connecting seat 6 is fixed, and a U-shaped frame 7 is fixed above the connecting seat 6. A contact platform 8 is placed on the top of the U-shaped frame 7. A vibration motor 9 is installed inside the U-shaped platform, and the output end of the vibration motor 9 contacts the bottom of the contact platform 8. A servo motor 10 is installed on the side wall of one of the mounting brackets 3. The output end of the servo motor 10 is connected to a drive shaft 11. A driven shaft 12 is fixed at the end of the rotating shaft 4 near the servo motor 10. Spur gears 13 are fixed on the outer surfaces of both the drive shaft 11 and the driven shaft 12, and the two spur gears 13 mesh with each other.
[0019] The mold base 1 rotates around the shaft 4. The servo motor 10 drives the spur gear 13 to mesh and transmit the rotational motion of the motor, which is converted into the flipping motion of the mold base 1. The linear driver 5 can realize the contact table 8 and the mold base 1 to contact or separate, providing support or removing support for the mold base 1. The vibration generated by the vibration motor 9 is transmitted to the mold base 1 through the contact table 8, and the vibration is used to make the cement part detach from the mold.
[0020] like Figure 1 and Figure 2As shown, in this embodiment, a cover plate 14 that can be placed on the mold base 1 is also included. Connecting blocks 15 are fixed at both ends of the bottom of the cover plate 14. When the cover plate 14 is placed on the top of the mold base 1, the connecting blocks 15 are outside the mold base 1. A through hole is opened through the side wall of the connecting block 15, and an insertion hole is opened on the side wall of the mold base 1. An insertion rod is provided that can be inserted into the through hole and the insertion hole to connect the connecting block 15 and the mold base 1. A storage groove 61 for inserting the cover plate 14 is opened on the outer wall of the connecting base 6. A storage hole 62 for inserting the insertion rod is also opened on the outer wall of the connecting base 6. When the cover plate 14 and the insertion rod are not used, the cover plate 14 and the insertion rod are placed in the storage groove 61 and the storage hole 62, respectively.
[0021] The cover plate 14 and the mold base 1 are detachably connected by inserting a rod. The cover plate 14 is fixed to the mold base 1 by mechanical limiting to prevent the cement parts from tipping over when flipped. The storage slot 61 and storage hole 62 on the connecting seat 6 provide dedicated storage space for the cover plate 14 and the rod, so as to achieve orderly storage of auxiliary components.
[0022] The working principle of this utility model is as follows:
[0023] When demolding is required, first place the cover plate 14 on top of the mold base 1 and insert the insert rod to connect the cover plate 14 to the mold base 1, preventing subsequent cement parts from tipping over because they are not adhered to the mold base 1. Activate the linear actuator 5 to retract, causing the connecting seat 6, U-shaped frame 7, and contact platform 8 to move away from the mold base 1, releasing the auxiliary support for the mold base 1. Then, activate the servo motor 10. The output shaft of the servo motor 10 drives the drive shaft 11 to rotate. Through the meshing of the spur gear 13, the driven shaft 12 rotates accordingly, thereby causing the mold base 1 to rotate 180 degrees. The mold base 1 rotates 180 degrees synchronously with the driven shaft 12, changing the originally upward-facing opening to a downward-facing one.
[0024] Restart the linear actuator 5 to extend its telescopic end, causing the contact table 8 to move upwards until it contacts the cover plate 14 below the mold base 1. At this point, remove the insert rod to release the fixed connection between the cover plate 14 and the mold base 1. Start the vibration motor 9. The high-frequency vibration generated by the vibration motor 9 is transmitted to the cover plate 14 through the contact table 8, and then from the cover plate 14 to the cement component inside the mold base 1. Under the action of vibration, the adhesion between the cement component and the inner wall of the mold base 1 is broken, and it gradually detaches from the mold.
[0025] Finally, the linear actuator 5 is activated to retract, and the contact table 8 descends accordingly. Due to gravity, the cement part descends along with the cover plate 14 and the contact table 8. When it reaches the appropriate position, the operator can easily remove the cement part from the cover plate 14, completing the entire demolding process.
[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
