Description

Technical Field

[0001] This utility model relates to the field of preform molding technology, and in particular to a vibration structure for preform molding. Background Technology

[0002] With the booming development of industrialized construction, precast components are increasingly widely used in various construction projects due to their advantages such as high construction efficiency, controllable quality, energy saving, and environmental protection. From common precast floor slabs and wall panels to complex bridge components and municipal culverts, precast components have become an indispensable and important part of the modern construction field. The precast component forming process, as a key link in ensuring its quality and performance, directly affects the structural safety and service life of buildings.

[0003] Referring to existing patent publication number CN212666323U, a vibration molding device for producing precast cement components for hydraulic engineering is disclosed. Rollers are equidistantly arranged within a concave space at the top of the support. A mold is placed on top of the rollers, and a raised edge is arranged around the outer wall of the mold. A top cover is provided on the top of the mold, and the top cover is fitted over the mold. This vibration molding device for producing precast cement components for hydraulic engineering employs a structure of a top cover and a mold, allowing the vibration molding process to take place within a closed space, thereby preventing cement from splashing during vibration.

[0004] However, during the molding process of existing precast components, due to the different particle sizes and shapes of concrete raw materials (such as cement, sand, and stone), uneven particle distribution and residual air bubbles inevitably occur during mixing and pouring, which will lead to quality hazards such as pores and honeycomb inside the precast components. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a vibration structure for preform molding. This invention connects a transmission assembly to the lower part of the molding die, so that during the molding process, the molding die is in the upper position, i.e., the support member and the cam are spaced apart. During the operation of the transmission assembly, the striking member, under the action of the motor and drive shaft, can cyclically and regularly vibrate the molding die, thereby compacting the raw material within the mold cavity, reducing gaps in the raw material, and improving molding quality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A vibration structure for preform molding, comprising:

[0008] The base plate has vertical plates fixed to both sides of its upper part;

[0009] A forming mold is connected between the vertical plates, and the forming mold can move vertically by a driving mechanism. A cover plate is fitted on the upper part of the forming mold.

[0010] A mold cavity is disposed inside the molding die, and an ejector assembly extending into the mold cavity is connected inside the molding die.

[0011] A transmission assembly located below the forming mold connects the vertical plates.

[0012] The present invention further provides that the driving mechanism includes: a hydraulic cylinder and a piston rod;

[0013] The hydraulic cylinder is mounted on the surface of the vertical plate, and the piston rod is connected to the output end of the hydraulic cylinder. One end of the piston rod is equipped with a connecting plate that is connected to the forming mold.

[0014] The present invention is further configured such that the surface of the vertical plate has a limiting groove, and a guide is connected inside the limiting groove, the guide being connected to the connecting plate.

[0015] The present invention is further configured such that the top material assembly includes: a top plate, a support member, and an elastic member 2;

[0016] The support member is constructed inside the molding die and one end extends into the mold cavity. The top plate is installed at the end of the support member that extends into the mold cavity, and the second elastic member is connected between the support member and the mold cavity.

[0017] The present invention is further configured such that the lower part of the molding die has an opening located directly below the support member, and the width of the opening is smaller than the width of the support member.

[0018] The present invention is further configured such that the transmission assembly includes: a motor, a drive shaft, a cam, an elastic element, and a striking element;

[0019] The motor is mounted on the surface of the vertical plate, the drive shaft is connected to the output end of the motor, the cams are all mounted on the surface of the drive shaft, and the striking parts are all connected to the surface of the drive shaft through elastic elements.

[0020] The present invention is further configured such that all the cams are located directly below the opening.

[0021] The present invention is further configured such that the striking element and the cam are staggered.

[0022] The present invention is further configured such that the length of the elastic element is greater than the distance between the cam and the support element.

[0023] The beneficial effects of this utility model are as follows: By connecting a transmission component to the lower part of the molding mold, the molding mold is located in the upper position when the preform is being molded, that is, the support and the cam are in a spaced-out state. At this time, during the operation of the transmission component, the striking component can circulate and regularly strike the molding mold under the action of the motor and the drive shaft, thereby vibrating and compacting the raw material in the mold cavity to a certain extent, so as to reduce the gaps in the raw material and improve the molding quality.

[0024] 1. The vibration structure for preform molding, by means of a transmission component, allows the molding die to be in the upper position during the molding process. At this time, the hydraulic cylinder is activated, which pushes the piston rod to extend, thereby moving the molding die upward. That is, the support and the cam are in a spaced-out state. During the operation of the transmission component, the striking component can cyclically and regularly strike the molding die under the action of the motor and drive shaft, thereby vibrating and compacting the raw material in the mold cavity to a certain extent, reducing the gaps in the raw material and improving the molding quality.

[0025] 2. The vibration structure for preform molding, through the cooperation of the ejector assembly and the transmission assembly, allows the hydraulic cylinder to retract the piston rod after the preform is formed, which in turn moves the mold downward. As the transmission assembly operates, the cam acts on the support, pushing it to lift the molded part from the mold cavity, facilitating demolding. The structure is easy to operate, and vibration and demolding can be performed under the same transmission assembly, improving overall adaptability and performance. Attached Figure Description

[0030] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0031] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

They are used only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this patent.

[0033] In the description of this patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0034] Reference Figures 1 to 3 A vibration structure for precast component molding includes: a base plate 1 with vertical plates 2 fixed on both sides of its upper part; a molding mold 4 connected between the vertical plates 2, the base plate 1 and the vertical plates 2 providing support for the molding mold 4, and the molding mold 4 being able to move vertically via a drive mechanism, giving the molding mold 4 a certain amount of room to move and making it more flexible to cooperate with subsequent transmission components; a cover plate 7 fitted on the upper part of the molding mold 4, which can effectively prevent concrete from overflowing from the upper part of the mold cavity, keeping the molding site clean and avoiding concrete waste; a mold cavity 5 located inside the molding mold 4, with a top-ejector component extending into the mold cavity 5 connected inside the molding mold 4, which can smoothly eject the precast component from the mold cavity by lifting it upward after the precast component is molded, achieving rapid demolding; and a transmission component located below the molding mold 4 connected between the vertical plates 2, which can transmit power to the top-ejector component and the molding mold 4 under the action of driving force, realizing the transmission and application of force, and providing stable vibration power for the entire vibration structure, ensuring the stability of vibration frequency and amplitude.

[0035] Specifically, refer to Figure 2The driving mechanism includes a hydraulic cylinder 10 and a piston rod 11. The hydraulic cylinder 10 is mounted on the surface of the vertical plate 2, and the piston rod 11 is connected to the output end of the hydraulic cylinder 10. One end of the piston rod 11 is equipped with a connecting plate 3 that is connected to the forming mold 4. In this embodiment, when the preform is formed, the hydraulic cylinder 10 can be activated to push the piston rod 11 to extend, thereby driving the forming mold 4 to move upward. At this time, the support member 18 and the cam 14 are in a spaced-out state. At this time, the transmission component will act on the forming mold 4 to generate a certain vibration. After forming, the hydraulic cylinder 10 retracts the piston rod 11, which will drive the mold to move downward. At this time, the cam 14 in the transmission component will act with the ejector component to realize the demolding operation, which is more flexible.

[0036] Furthermore, the surface of the vertical plate 2 has a limiting groove 9, and a guide 8 is connected inside the limiting groove 9. The guide 8 is connected to the connecting plate 3. Through this design, the limiting groove 9 provides a fixed running track for the guide 8. The guide 8 is connected to the connecting plate 3, and the connecting plate 3 drives the molding die 4 to move. This design strictly limits the movement of the molding die 4 in the vertical direction to a straight trajectory, avoiding problems such as shaking, offset or tilting of the die during movement and vibration.

[0037] Specifically, refer to Figures 2 to 3 The ejector assembly includes: an ejector plate 12, a support member 18, and an elastic member 19. The support member 18 is constructed inside the molding die 4 and extends through the mold cavity 5 at one end. The ejector plate 12 is installed at the end of the support member 18 that extends through the mold cavity 5. The elastic member 19 connects the support member 18 and the mold cavity 5. In this embodiment, the ejector plate 12 is located inside the mold cavity 5, so that when raw material is injected into the mold cavity 5, the raw material will press the ejector plate 12 and be supported by the support member 18, thereby forming a connection, so that the ejector plate 12 can be lifted when force is applied to the support member 18 later.

[0038] Furthermore, the lower part of the molding die 4 has an opening 17 located directly below the support member 18, and the width of the opening 17 is smaller than the width of the support member 18. With this design, the support member 18 can be well connected and supported in the molding die 4, thereby avoiding detachment from the opening 17, and facilitating the movement of subsequent components in the opening 17 and their interaction with the support member 18.

[0039] Specifically, refer to Figures 1 to 3The transmission components include: a motor 6, a drive shaft 13, a cam 14, an elastic element 15, and a striking element 16. The motor 6 is mounted on the surface of the vertical plate 2, the drive shaft 13 is connected to the output end of the motor 6, the cam 14 is mounted on the surface of the drive shaft 13, and the striking element 16 is connected to the surface of the drive shaft 13 through the elastic element 15. In this embodiment, after the motor 6 is started, it can drive the drive shaft 13 to rotate. At this time, the elastic element 15 and the striking element 16 connected to the drive shaft 13 can rotate together, thereby causing regular vibration to the molding die 4. Although the cam 14 can also rotate together, the molding die 4 is in a raised state during the vibration process and does not interact with the ejector assembly.

[0040] Furthermore, all cams 14 are located directly below the opening 17. With this design, the drive shaft 13 will drive the cams 14 to move together when it is running. At this time, the opening 17 provides space for the cams 14 to move, thus avoiding interference.

[0041] Furthermore, the striking element 16 is staggered from the cam 14, and the length of the elastic element 15 is greater than the distance between the cam 14 and the support element 18. Through this design, the impact on the mold and the ejection operation can move under the same transmission component and do not affect each other. That is, the impact on the ejection component is not affected during the impact operation. The corresponding process is reasonably laid out to improve the space utilization rate.

[0042] Working principle: When using this utility model, the raw material is first injected into the mold cavity 5, and then the mold 4 is sealed by the cover plate 7. At this time, the mold 4 is located in the upper position. The hydraulic cylinder 10 is activated to push the piston rod 11 to extend, thereby moving the mold 4 upward. At this time, the support member 18 and the cam 14 are in a spaced-out state. During the operation of the transmission component, the striking member 16 can circulate and regularly vibrate the mold 4 under the action of the motor 6 and the drive shaft 13, thereby vibrating and compacting the raw material in the mold cavity 5 to reduce the gaps in the raw material and improve the molding quality. After molding, the cover plate 7 can be opened, and the piston rod 11 is retracted by the hydraulic cylinder 10, which will drive the mold downward. With the operation of the transmission component, the cam 14 will act on the support member 18, so that the cam 14 can push the support member 18 during the movement, so that the top plate 12 can lift the molded part in the mold cavity 5 for easy demolding. The operation is convenient. Vibration and demolding can be carried out under the action of the same transmission component, improving the overall adaptability and use effect.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
