Technical Field
[0001] The present application relates to the technical field of cement shaping molds, and in particular to a shaping mold for producing cement products. Background Art
[0002] Cement products are obtained by mixing powdered cement with water, sand and other materials and adding the mixture into a mold for forming. A shaping mold is required during the forming process. The existing cement product shaping mold is composed of a mold base, a mold frame, an ejection demoulding mechanism and other structures.
[0003] During the cement product production operation, the fluid material is first added into the mold frame, and then the material on the upper end of the mold frame is scraped flat. After the material in the mold frame is dried and formed, the ejection mechanism is started to separate the formed cement product from the mold frame.

[0038] like Figure 1-4 As shown, the present application proposes a shaping mold for cement product production, comprising a support base 1 and a mold frame 2 arranged at the upper end thereof, wherein the mold frame 2 can be separated from the support base 1, and the support base 1 is supported by a base frame 15, and there is a certain distance between the lower surface of the support base 1 and the bottom inner wall of the base frame 15, and a pair of first cylinders 10 are installed on the bottom inner wall of the base frame 15, and the telescopic ends of the two first cylinders 10 are fixedly connected to the protrusions on the two side walls of the mold frame 2; by starting the first cylinder 10, the mold frame 2 can be driven to move upward, thereby facilitating the removal of the cement product shaped in the mold frame 2.
[0039] The mold base 3 is slidably connected in the mold frame 2, and a stripper plate 4 is embedded in the mold base 3 (the stripper plate 4 is vertically slidably connected to the mold base 3). The mold base 3, the stripper plate 4 and the mold frame 2 form a matching molding space. It also includes a return groove 101 provided at the upper end of the support base 1, and the mold frame 2 is clamped in the return groove 101. The inner wall of the return groove 101 is fixedly connected to a support base 102 for supporting the mold base 3, and a control cavity 13 is provided in the support base 102; the upper end surface of the support base 102 is higher than the upper end surface of the support base 1, so that the bottom end surface of the formed cement product is higher than the upper end surface of the support base 1, so as to facilitate pushing the cement product to one side, and then taking out the demoulded cement product. The lower end surface of the support base 1 is fixedly connected to an air guide hood 6 provided on the outside of the control cavity 13. A pneumatic plate 8 is slidably connected in the air guide cover 6, and a transmission plate 7 is fixedly connected to the bottom end of the pneumatic plate 8. A pair of second cylinders 12 are installed at the bottom end of the support seat 1. Both sides of the bottom end of the transmission plate 7 are fixedly connected with convex plates 11. The telescopic ends of the two second cylinders 12 are respectively fixedly connected to the two convex plates 11, and the transmission plate 7 can be driven to rise by the second cylinders 12. The upper end of the pneumatic plate 8 is fixedly connected with a plurality of push rods 9 that slide through the bottom end of the support seat 1 and extend into the control chamber 13. The upper ends of the plurality of push rods 9 are commonly fixedly connected with a lift plate 5, and the lift plate 5 is fixedly connected to the mold base 3, and the lift plate 5 is not fixed to the stripper plate 4.
[0040] The bottom end of the stripper plate 4 is provided with a pneumatic ejector 14 located inside the control cavity 13 ; after the mold base 3 is lifted up, the stripper plate 4 protrudes out of the upper end surface of the mold base 3 .
[0041] Specifically, the pneumatic ejector 14 is provided with two groups, and the stripper plate 4 is also provided with two groups, and the two groups of pneumatic ejector 14 are respectively located at the lower ends of the two stripper plates 4. The pneumatic ejector 14 includes a gas cylinder 141 fixedly connected to the inner wall of the lower end of the support seat 1 and located in the control chamber 13, and a piston plate 142 is pneumatically connected to the gas cylinder 141, and a pneumatic rod 144 is fixedly connected to the upper end of the piston plate 142, and the pneumatic rod 144 is fixedly connected to the bottom end of the stripper plate 4. A pneumatic hole 143 is opened at the bottom end of the support seat 1, and the pneumatic hole 143 is located directly below the piston plate 142.
[0042] The two side walls of the air guide cover 6 are provided with exhaust holes 601, and the exhaust holes 601 are located in the middle and lower part of the air guide cover 6, and there is a gap between the top of the exhaust holes 601 and the top of the air guide cover 6. When the pneumatic plate 8 rises in the initial stage, the gas inside the air guide cover 6 is discharged outward through the two exhaust holes 601, thereby driving the push rod 9 to stop driving the pneumatic ejector 14; after the pneumatic plate 8 moves to the top of the exhaust holes 601, the gas inside the air guide cover 6 is squeezed upward, thereby driving the pneumatic ejector 14.
[0043] The working principle of this embodiment is as follows: when processing cement products, first add the fluid material into the mold frame 2 (at this time, the mold base 3 inside the mold frame 2 is flush with the upper end surface of the stripping plate 4 and is located at the inner bottom of the mold frame 2). After the material is added, the upper end surface is flattened, and the mold is removed after it is dried and formed. When specifically demolding, first start the two second cylinders 12, so that the telescopic ends of the two second cylinders 12 are retracted to drive the two convex plates 11 to move upward, and then drive the pneumatic plate 8 to move upward through the transmission plate 7. When the pneumatic plate 8 initially moves upward, the gas inside the air guide 6 is discharged outward through the two exhaust holes 601, and when the pneumatic plate 8 moves upward, the lifting plate 5 is lifted upward by a number of push rods 9. When the lifting plate 5 is lifted upward, the cement product formed on the upper end of the mold base 3 is pushed upward to a certain height, so that the shaped cement product is loosened from the inner wall of the mold frame 2 and separated from the inner wall of the mold frame 2. By arranging the stripper plate 4 inside the mold base 3 and arranging the pneumatic ejector 14 at the bottom end of the stripper plate 4, when the push rod 9 moves to the top of the exhaust hole 601, the gas inside the air guide cover 6 will be squeezed into the air cylinder 141 through a plurality of pneumatic holes 143, and the piston plate 142 inside the air cylinder 141 will be pushed up under the action of the air pressure, and then the stripper plate 4 will be pushed up to a certain height through the pneumatic rod 144, so that the bottom of the shaped cement product will be separated from the mold base 3. After the shaped cement product is separated from the mold frame 2 and the mold base 3, the telescopic end of the second cylinder 12 is extended, so that the mold base 3 and the stripper plate 4 are restored to their original state, and the next step is to start the two first cylinders 10, so that the telescopic ends of the two first cylinders 10 are extended, and then the mold frame 2 is pushed up, so that the mold frame 2 rises to the top of the cement product, and finally the cement product is horizontally removed to one side (because the upper end surface of the support base 102 is higher than the upper end surface of the support base 1, so that the cement product can be smoothly pushed to one side).
[0044] The above-mentioned specific embodiments are merely preferred embodiments of the present application. Based on the technical solutions of the present application and the relevant inspirations of the above-mentioned embodiments, those skilled in the art may make various alternative improvements and combinations to the above-mentioned specific embodiments. The above-mentioned specific embodiments are merely explanations of the present application, and they are not limitations of the present application.
