Description

Technical Field

[0001] This utility model relates to the field of wall panel mold technology, and in particular to a mold assembly for prefabricated building wall panels. Background Technology

[0002] When using existing building wall panels, prefabricated building wall panels require the use of molds for production. Prefabricated building wall panels are relatively easy to assemble, but in the production process, molds are required. During the production process, cement needs to be poured into the inside of the mold, and then the water in the cement needs to be evaporated to form the wall panel.

[0003] However, in the use of existing molds, the size of the wall panels produced is fixed and cannot be adjusted according to the required size of the wall panels. This causes inconvenience to operators when different sizes of wall panels need to be produced, and also leads to slow production of prefabricated building wall panels. Utility Model Content

[0004] The purpose of this utility model is to provide a mold assembly for prefabricated building wall panels to solve at least any of the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold assembly for prefabricated building wall panels, comprising a support frame, an installation groove formed around the top of the inner cavity of the support frame, a heating rod disposed within the inner cavity of the installation groove, a cover plate disposed on the top of the support frame, a first threaded hole and a second threaded hole respectively formed around the top of the cover plate and the support frame, support columns fixedly connected around the bottom of the support frame, a connecting plate disposed between the four support columns, and an injection molding assembly and a cooling assembly disposed on the top of the connecting plate respectively.

[0006] Preferably, a first threaded hole and a second threaded hole are arranged as a group, and a total of four groups are provided. The inner cavities of the first threaded hole and the second threaded hole in each group are threadedly connected to a fixing bolt.

[0007] Preferably, the injection molding assembly includes four electric telescopic rods fixedly connected to the top perimeter of the connecting plate. A fixed frame is provided at the top of the output ends of the four electric telescopic rods. Movable slots are provided on both sides of the top of the fixed frame. A motor is provided on the right side of the fixed frame. A bidirectional lead screw is fitted onto the output end of the motor. Positioning plates are fitted onto both sides of the middle portion of the bidirectional lead screw. A lead screw groove, compatible with the bidirectional lead screw, is provided through the middle of each of the two positioning plates. An adjusting plate is fixedly connected to the top of each of the two positioning plates.

[0008] Preferably, the positioning plates are all fitted into the middle of the bidirectional lead screw through a lead screw groove and are all slidably connected to the fixed frame within the moving groove.

[0009] Preferably, there are four support columns arranged in a matrix array around the bottom of the support frame, and the bottom of each support column is frosted.

[0010] Preferably, the cooling component includes a low-temperature device fixedly connected to the top left side of the connecting plate, an air extraction pipe is sleeved on the left side of the low-temperature device, an air extraction pump is sleeved in the middle of the air extraction pipe, an air inlet pipe is sleeved on the top of the air extraction pipe, and multiple nozzles are sleeved on one side of the air inlet pipe.

[0011] Preferably, the nozzles do not contact the fixed frame and are spaced apart by a distance equal to the thickness of the support column.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, the output end of the motor drives the bidirectional lead screw to rotate. When the bidirectional lead screw rotates, it drives the two positioning plates to move in opposite directions through the two lead screw slots, thereby adjusting the distance between the two adjusting plates. After adjustment, the size of the inner cavity of the fixed frame is the same as the distance between the two adjusting plates. This allows the operator to automatically adjust the size of the inner cavity of the fixed frame according to the size of the wall panel to be injection molded, making the device versatile.

[0014] 2. In this utility model, the heating rod generates heat and contacts the inner wall of the fixed frame, subjecting it to high temperature. This rapidly evaporates the moisture in the concrete inside the fixed frame, forming a wall panel. This reduces the injection molding time required for wall panel production. Furthermore, by turning the fixing bolt counterclockwise through the first and second threaded holes, the cover plate is released from the support frame, allowing the operator to easily remove the heating rod from the mounting slot inside the support frame for replacement. A low-temperature device generates low-temperature gas, which is then drawn through the suction pipe by a vacuum pump and sent to the inlet pipe. Finally, the low-temperature gas is sprayed onto the fixed frame through multiple nozzles, facilitating rapid cooling and removal of the injection-molded wall panel. Therefore, this device is convenient to use. Attached Figure Description

[0020] 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 protection scope of the present utility model.

[0021] This utility model provides, for example Figure 1-4 The mold assembly for prefabricated building wall panels shown includes a support frame 1. The support frame 1 has an installation groove 2 around the top of its inner cavity. A heating rod 3 is installed inside the installation groove 2. A cover plate 4 is installed on the top of the support frame 1. The cover plate 4 and the top of the support frame 1 have a first threaded hole 5 and a second threaded hole 6 respectively. Support columns 8 are fixedly connected to the bottom of the support frame 1. A connecting plate 9 is installed between the four support columns 8. An injection molding component and a cooling component are respectively installed on the top of the connecting plate 9.

[0022] Furthermore, a first threaded hole 5 and a second threaded hole 6 are arranged as a group, and a total of four groups are provided. The inner cavity of each group of first threaded holes 5 and second threaded holes 6 is threadedly connected with a fixing bolt 7. By turning the fixing bolt 7 counterclockwise in the first threaded hole 5 and the second threaded hole 6 to remove it, the fixing of the cover plate 4 and the support frame 1 is released, making it easy for the operator to remove the heating rod 3 from the mounting groove 2 inside the support frame 1 for replacement.

[0023] Furthermore, the injection molding assembly includes four electric telescopic rods 10 fixedly connected to the top of the connecting plate 9. A fixed frame 11 is provided at the top of the output end of each of the four electric telescopic rods 10. Movable slots 12 are provided on both sides of the top of the fixed frame 11. A motor 13 is provided on the right side of the fixed frame 11. A bidirectional lead screw 14 is fitted at the output end of the motor 13. Positioning plates 15 are fitted on both sides of the middle of the bidirectional lead screw 14. A lead screw groove 16, which is compatible with the bidirectional lead screw 14, is provided through the middle of each of the two positioning plates 15. An adjusting plate 17 is fixedly connected to the top of each of the two positioning plates 15. The positioning plates 15 are fitted into the middle of the bidirectional lead screw 14 through the lead screw groove 16 and are slidably connected to the fixed frame 11 within the movable slot 12. With this injection molding assembly, the operator can easily adjust the size of the cavity inside the fixed frame 11 according to the size of the wall panel to be injection molded, thus enabling the device to have diverse usage effects.

[0024] Furthermore, a total of four support columns 8 are arranged in a matrix array around the bottom of the support frame 1. The bottom of each support column 8 is frosted. With four support columns 8 and frosted bottoms, the support frame 1 can be balanced when supported. At the same time, the frictional resistance with the ground can be increased when supporting, preventing the device from moving on its own. This ensures the stability of the device during use.

[0025] Furthermore, the cooling component includes a low-temperature device 18 fixedly connected to the top left side of the connecting plate 9. A suction pipe 19 is sleeved on the left side of the low-temperature device 18. A suction pump 20 is sleeved in the middle of the suction pipe 19. An air inlet pipe 21 is sleeved on the top of the suction pipe 19. Multiple nozzles 22 are sleeved on one side of the air inlet pipe 21. The nozzles 22 do not contact the fixed frame 11 and are spaced apart by a distance of the same thickness as the support column 8. With the cooling component, it is convenient for operators to quickly cool down and remove the injection-molded wall panel, thus making the device easy to use.

[0026] In practical implementation, this invention first drives the bidirectional lead screw 14 to rotate via the output end of the motor 13. When the bidirectional lead screw 14 rotates, it drives the two positioning plates 15 to move in opposite directions within their corresponding moving slots 12 via the two lead screw grooves 16. This adjusts the distance between the two adjusting plates 17, ensuring that the size of the inner cavity of the fixed frame 11 is the same as the distance between the two adjusting plates 17. This allows the operator to automatically adjust the size of the inner cavity of the fixed frame 11 according to the size of the wall panel to be injection molded, giving the device versatility. After adjustment, the wall panel can be injection molded into the inner cavity of the fixed frame 11. At this time, the heating rod 3 generates heat, which comes into contact with the inner wall of the fixed frame 11, subjecting it to high temperatures. This rapidly evaporates the moisture in the concrete inside the fixed frame 11, forming the wall panel and reducing the cost of wall panel production. During the injection molding process, the output ends of four electric telescopic rods 10 drive the fixed frame 11 to rise and move out from the middle of the inner cavity of the support frame 1. After moving out, the low-temperature device 18 generates low-temperature gas, which is then pumped into the air inlet pipe 21 by the air pump 20 through the air extraction pipe 19. Finally, the low-temperature gas is sprayed onto the fixed frame 11 through multiple nozzles 22, which makes it easy for the operator to quickly cool down and remove the injection-molded wall panel. This makes the device easy to use. When the heating rod 3 needs to be replaced, the fixing bolt 7 is turned counterclockwise in the first threaded hole 5 and the second threaded hole 6 to release the cover plate 4 from the support frame 1 and open it, so that the operator can easily take the heating rod 3 out of the mounting groove 2 inside the support frame 1 for replacement.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
