Technical Field

[0001] This utility model relates to the field of precast component production equipment technology, and in particular to a precast component demolding device. Background Technology

[0002] Precast components refer to steel, wood, or concrete components that are prefabricated in a factory or on-site according to design specifications. Small precast concrete components refer to concrete products manufactured in factories using standardized and mechanized methods. They are widely used in construction, transportation, water conservancy, and other fields, playing an important role in the national economy. Small precast concrete components require on-site molding and pouring processes, and need to be demolded after molding.

[0003] The most common demolding method nowadays is to flip the mold over for support and then manually strike the side of the mold with a rubber mallet to separate it. However, this method requires a lot of manual labor and can easily damage the mold or product during the striking process, resulting in a short service life.

[0004] Therefore, a precast component demolding device is proposed. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To overcome the shortcomings of existing technologies, a precast component demolding device is proposed to solve the problem that the current method of manually knocking precast components for demolding products easily damages the mold or the product, resulting in a short service life.

[0008] This utility model is achieved through the following technical solution: This utility model proposes a precast component demolding device, including a base with an internal working cavity. A transmission rod one and a transmission rod two are diagonally and rotatably installed inside the working cavity, with rotating threads mirrored on both sides of the transmission rod one and transmission rod two from the center. A first motor and a second motor are installed at the outer corner of the base. The output end of the first motor is connected to the transmission rod one, and the output end of the second motor is connected to the transmission rod two. Sliding sliders are symmetrically installed on the sides of the transmission rod one and transmission rod two, slidingly connected to the upper and lower inner walls of the working cavity. Each sliding slider has a threaded hole connected to the rotating thread. A through-hole sliding groove is provided on both sides of the top surface of the working cavity located on the transmission rod one and transmission rod two. A clamping plate is connected to the upper end of the sliding slider through the sliding groove via a connecting slider.

[0009] The clamping plate has an installation cavity inside, and a first electric push rod is installed inside the installation cavity. The top of the clamping plate has a storage groove, and a push block is installed inside the storage groove. The output end of the first electric push rod is connected to the push block.

[0010] Furthermore, the working cavity is provided with a reinforcing plate at the distance between the intersection of transmission rod one and transmission rod two, connecting the upper and lower ends of the working cavity.

[0011] Furthermore, a second electric push rod is provided at the center of the upper surface of the base, and the output end of the second electric push rod is connected to a mounting plate.

[0012] Furthermore, several telescopic rods are installed on the outer side of the mounting plate and connected to the base.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] 1. In this utility model, by placing the mold on the upper end of the mounting plate, and adjusting the height of the mold with the second electric push rod at the lower end, the finished product at the lower end of the mold protrudes to the clamping position of the clamping plate.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] Please see Figures 1-4This utility model provides a precast component demolding device, including a base 1 with an internal working cavity, which is fixed on the ground or workbench to prevent movement under stress and improve stability. A controller 110 is installed on the outside of the base 1, which facilitates operation of the electrical components in the device through an externally purchased controller, making operation more convenient. A second electric push rod 18 is provided at the middle of the upper surface of the base 1, and the output end of the second electric push rod 18 is connected to a mounting plate 17. The mounting plate 17 allows the operator to place the mold upside down on it for demolding. The height of the mounting plate 17 can be adjusted by the push of the second electric push rod 18, so that the protruding end of the finished product at the lower end of the mold can be adjusted to be clamped on the side. The clamping height of plate 12 increases the force-bearing area during clamping, resulting in a better clamping effect. Several telescopic rods 19 are installed on the outer side of the mounting plate 17 and connected to the base 1. The telescopic rods 19 enhance the stability of the side mounting plate 17, resulting in better stability. Inside the working cavity, transmission rod 1 2 and transmission rod 2 3 are installed diagonally and vertically offset to rotate under force, allowing the corresponding clamping plates 12 on either transmission rod 1 2 or transmission rod 2 3 to move simultaneously under force. Both transmission rod 1 2 and transmission rod 2 3 have rotating threads mirrored from the center on both sides, allowing the clamping plates 12 to move inward or outward simultaneously when transmission rod 1 2 or transmission rod 2 3 rotates. This allows the clamping plates 12 to clamp or loosen the molded product, thus... When clamped, the mold can be positioned in the middle of the mounting plate 17. A first motor 4 and a second motor 5 are installed at the outer corner of the base 1. The output end of the first motor 4 is connected to transmission rod 2, and the output end of the second motor 5 is connected to transmission rod 3. Thus, the first motor 4 and the second motor 5 drive transmission rod 2 and transmission rod 3 to rotate, resulting in better rotation and eliminating the need for manual clamping, thus improving practicality. Sliding sliders 7 are symmetrically installed on the sides of transmission rods 2 and 3, slidingly connected to the upper and lower inner walls of the working cavity. The sliding sliders 7 fit snugly against the upper and lower surfaces of the working cavity, facilitating clamping and demolding under stress, preventing damage to the rotating threads under stress, and improving usability. Furthermore, the internal components of the sliding sliders 7... All components are equipped with threaded holes 8 for rotational thread connection, allowing the movable slider 7 to move left and right under force, and enabling the upper clamping plate 12 to clamp and loosen under force. The top surface of the working cavity has through-hole sliding grooves 10 on both sides of the transmission rod 2 and transmission rod 3. The upper end of the movable slider 7 is connected to the clamping plate 12 via a connecting slider 11 that passes through the sliding grooves 10. The connecting slider 11 slides in close contact with the sliding grooves 10, improving stability and limiting rotation to prevent tipping. The bottom surface of the base 1 has a material discharge groove 9 corresponding to the sliding groove 10, penetrating the inside and outside of the working cavity. The material discharge groove 9 prevents fragments from falling into the working cavity during clamping and demolding, facilitating their discharge and minimizing impact on operation.A reinforcing plate 6 is installed at the gap between the intersection of transmission rod 1 (2) and transmission rod 2 (3) to connect the upper and lower ends of the working cavity. The reinforcing plate 6 strengthens the base 1, resulting in better support and greater stability.

[0026] The clamping plate 12 has an installation cavity 13 inside, and a first electric push rod 14 is installed inside the installation cavity 13. The top of the clamping plate 12 has a storage groove 15, and a push block 16 is set inside the storage groove 15. This allows the push block 16 to be retracted and stored under the action of the storage groove 15, preventing the upper length from being too long when clamping, which would reduce the clamping surface with the finished product. This allows for demolding after clamping, resulting in a better demolding effect. The output end of the first electric push rod 14 is connected to the push block 16. Under the action of the first electric push rod 14, the push block 16 is pushed upward to move upward, so that the push block 16 contacts the mold closing edge on the side of the mold. Then, under the force of the push block 16, the mold can be pushed upward to separate the finished product from the finished product when it is clamped and fixed by the side force. This achieves the demolding work, avoiding manual demolding by knocking, resulting in a better working effect and reducing damage.

[0027] Working principle: In use, first connect the first motor 4, the second motor 5, the first electric push rod 14, and the second electric push rod 18 to the controller 110 and connect them to an external power supply. Then, place the mold upside down on the upper end of the mounting plate 17. Based on the height between the protruding part of the mold side and the clamping plate 12, the second electric push rod 18 pushes the mounting plate 17 up and down to adjust the height of the mold, making it easier for the clamping plate 12 to clamp the side inward. Then, under the action of the first motor 4 and the second motor 5, the transmission rod 12 and the transmission rod 23 are rotated. The sliding slider 7 on both sides is pushed by the rotating threads, causing the sliding slider 7 on both sides to move inward and contact the finished product inside the mold. After clamping it, the first electric push rod 14 pushes the pushing block 16 inside the receiving groove 15 upward, so that the pushing block 16 contacts the mold closing part on the side of the mold and is subjected to force. In this way, with the finished product inside clamped and not moving, the mold is pushed upward during the upward process, thereby realizing the demolding work.
