Description

Technical Field

[0001] This utility model belongs to the field of precast component production mold technology, specifically a precast concrete component production mold. Background Technology

[0002] Concrete is an important material used in the construction industry; it is made by mixing cement, aggregates, water, and admixtures in a certain proportion; it is hard and has good compressive strength and durability; concrete can be cast into components of various shapes and sizes, providing stable support for high-rise buildings, bridges, roads, etc.; it is like the skeleton of a building, silently bearing the weight, witnessing the development and changes of the city, and is an indispensable cornerstone of modern architecture; in the production of concrete, precast concrete component production molds are generally used to solidify and shape the concrete.

[0003] Molds for producing precast concrete components are typically made of high-strength steel. Their structure includes a bottom mold, side molds, and end molds. The bottom mold provides stable support, while the side and end molds define the shape and size of the component. In principle, the mold's components are tightly joined to form a closed space into which the prepared concrete is poured. The inner walls of the mold are carefully designed and treated to ensure a smooth and flat surface for the precast component. During the concrete's setting process, the mold effectively restricts deformation, ensuring that the component meets the specified shape, size, and precision requirements, thus providing standardized, high-quality precast components for building construction.

[0004] Existing precast concrete component production molds have shortcomings in terms of concrete size design. Their structure cannot meet the production requirements of concrete with different diameters, which leads to reduced mold applicability. Different molds need to be replaced when producing concrete with different diameters. Furthermore, during the production process of existing precast concrete components, air bubbles are introduced during the pouring or mixing of concrete into the mold. These harmful air bubbles can damage the internal structural stability of the concrete, making it unusable. Therefore, a new precast concrete component production mold is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a production mold for precast concrete components.

[0006] The technical solution adopted by this utility model to solve its technical problem is a precast concrete component production mold, including a support base. The top of the support base is provided with a driving structure. The driving structure includes a driving layer. The driving layer is provided with four sets of No. 1 motors. The output end of the No. 1 motor is connected to a screw. The screw is provided with a slider. The slider has a threaded hole inside. The slider is rotatably connected to the screw. The top of the slider is welded to a support column. The top of the support column is welded to a template. The top of the driving layer is provided with a limiting plate. The limiting plate has limiting grooves around its perimeter. The support column passes through the limiting grooves and is welded to the template. A rectangular through hole is opened on one side of the limiting groove. A No. 3 spring is provided inside the rectangular through hole. A protective plate is welded to the other end of the No. 3 spring. A retaining slot is opened on the end of the protective plate away from the No. 3 spring. The retaining slot is a semi-circular hole. The diameter of the semi-circular hole is the same as that of the support column. The diameter of the mold can be adjusted by this structure.

[0007] Preferably, a protective shell is provided between the support bases. Four sets of No. 1 springs are welded to both sides of the inner wall of the protective shell. The other end of each No. 1 spring is welded to a connecting plate. A vibration box is provided inside the connecting plate. Four sets of No. 2 springs are welded to the top and bottom of the vibration box, respectively. The other end of the four sets of No. 2 springs on the top side of the vibration box is welded to the connecting plate. The four sets of No. 2 springs at the bottom of the vibration box are welded to the inner wall of the protective shell. This design causes the mold to vibrate and expel air bubbles.

[0008] Preferably, the vibration box is equipped with a second motor, the output end of which is connected to a drive shaft, and a turntable is provided outside the drive shaft; a top plate is provided at the center of the top of the vibration box, and the top plate is welded to the bottom of the drive layer; the templates are staggered and connected to each other, and the bottom of the template is relatively sealed to the top of the limiting plate; this structure increases the stability and practicality of the mold.

[0009] The advantages of this utility model are:

[0010] This utility model incorporates a vibration structure at the bottom of the mold. A motor drives a turntable, and the centrifugal force generated by the turntable's rotation vibrates the surrounding springs, causing the concrete inside the mold to vibrate. This vibration disperses or removes large air bubbles from the concrete, preventing it from becoming unusable due to harmful air bubbles. Furthermore, the addition of a drive structure at the bottom of the mold allows the motor to move the mold, thus adjusting the diameter of the concrete mold and increasing its usability.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-5As shown, a precast concrete component production mold includes a support base 1. The support base 1 has a driving structure at its top. The driving structure includes a driving layer 2, inside which are four sets of primary motors 3. The output ends of the primary motors 3 are connected to screws 4. Slider 5s are provided outside the screws 4, each with a threaded hole. The sliders 5 are rotatably connected to the screws 4. A support column 6 is welded to the top of the slider 5, and a template 7 is welded to the top of the support column 6. A limiting plate 8 is provided at the top of the driving layer 2, with limiting grooves 9 around its perimeter. The support column 6 passes through the limiting grooves 9 and is welded to the template 7. A rectangular through hole is provided on one side of the limiting groove 9, and a third spring 19 is installed inside the rectangular through hole. A protective plate is welded to the other end of the third spring 19. 20. The protective plate 20 has a notch 21 at the end away from the third spring 19. The notch 21 is a semi-circular hole with the same diameter as the support column 6. When concrete is poured, the operator starts the first motor 3, which drives the screw 4 to rotate. The slider 5 located outside the screw 4 moves towards the position of the first motor 3 under the drive of the screw 4, thereby moving the template 7. At the same time, the third spring 19 inside the limiting plate 8 pushes the protective plate 20 to move, thereby filling the gap created by the movement of the template 7 and preventing concrete from entering the limiting groove 9 and affecting the use of the mold. The four sets of templates 7 move in an alternating manner, causing the internal diameter of the template 7 to change. The operator can then adjust the diameter to a suitable size according to production needs before starting the pouring operation.

[0020] A protective shell 10 is provided between the support bases 1. Four sets of No. 1 springs 11 are welded to both sides of the inner wall of the protective shell 10. The other end of each No. 1 spring 11 is welded to a connecting plate 12. A vibration box 13 is provided inside the connecting plate 12. Four sets of No. 2 springs 14 are welded to the top and bottom of the vibration box 13 respectively. A No. 2 motor 16 is provided inside the vibration box 13. The output end of the No. 2 motor 16 is connected to a drive shaft 17. A turntable 18 is provided outside the drive shaft 17. A top plate 15 is provided at the center of the top of the vibration box 13. The top plate 15 is welded to the bottom of the drive layer 2. The other end of the four sets of No. 2 springs 14 on the top side of the box 13 is welded to the connecting plate 12; the four sets of No. 2 springs 14 at the bottom of the vibration box 13 are welded to the inner wall of the protective shell 10; when the concrete is vibrated to defoam, the operator starts the No. 2 motor 16, which drives the drive shaft 17 and makes the turntable 18 rotate. When the turntable 18 rotates at high speed, the turntable 18 itself generates centrifugal force and makes the vibration box 13 start to vibrate. Due to the vibration effect, the springs around the vibration box 13 start to vibrate, which causes the top plate 15 to drive the mold to vibrate, thereby completing the defoaming operation of the concrete.

[0021] Working principle: When pouring concrete, the operator starts motor 3, which drives screw 4 to rotate. The slider 5, located outside screw 4, moves towards motor 3, thus moving the template 7. Simultaneously, spring 19 inside limit plate 8 pushes protective plate 20, filling the gap created by the template 7 and preventing concrete from entering the limit groove 9 and affecting mold use. The staggered movement of the four templates 7 changes the internal diameter, which the operator adjusts to the appropriate size according to production needs before pouring. When vibrating to defoam the concrete, motor 16 is started, driving drive shaft 17 and rotating turntable 18. The high-speed rotation of turntable 18 generates centrifugal force, causing vibration box 13 to vibrate. This vibration causes the springs around vibration box 13 to vibrate, which in turn causes top plate 15 to vibrate the mold, thus completing the defoaming operation.
