Detailed Implementation

[0022] 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 (for ease of description and understanding, hereinafter referred to as...). Figure 4 (The above is described above). Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figure 1-7 This utility model provides a technical solution: a foam board pressing device for sand mold, including a support plate 1, a first positioning plate assembly 2, a second positioning plate assembly 3, and a pressing mechanism 6;

[0024] The first positioning plate assembly 2 and the second positioning plate assembly 3 are arranged opposite to each other and located at the upper end of the support plate 1. The first positioning plate assembly 2 and the second positioning plate assembly 3 have the same height position and the first positioning plate assembly 2 and the second positioning plate assembly 3 have the same structure.

[0025] The first positioning plate assembly 2 includes a square plate 21 and a groove 22. The groove 22 is located on one side of the square plate 21, and one end of the groove 22 is open. The groove 22 is used to place foam 4. The groove 22 in the second positioning plate assembly 3 is used to place plastic plate 5. The groove 22 limits the position of plastic plate 5 and foam 4, and the mating surfaces of plastic plate 5 and foam 4 protrude from the surface of square plate 21. One side of the first positioning plate assembly 2 is fixedly connected to the upright plate 8.

[0026] One side of the second positioning plate assembly 3 is connected to the pressing mechanism 6. Preferably, the pressing mechanism 6 is a hydraulic telescopic rod. The fixed end of the hydraulic telescopic rod is connected to the fixed plate 7. The fixed plate 7 is fixed on the upper surface of the support plate 1. The telescopic end of the hydraulic telescopic rod is connected to one side of the square plate 21 in the second positioning plate assembly 3. The pressing mechanism 6 is used to push the plastic plate 5 onto the surface of the foam 4 coated with glue to achieve a pressing connection.

[0027] Furthermore, to accommodate the pressing of foam 4 and plastic sheet 5 of different widths, adjustment mechanisms 23 are symmetrically arranged on the upper and lower sides of the groove 22 in the first positioning plate assembly 2. The adjustment mechanisms 23 are evenly distributed along the length of the square plate 1. The adjustment mechanism 23 includes a fixed cylinder 231, a telescopic column 232, a connecting frame 233, and a support wheel 234. The fixed cylinder 231 is fixed to the surface of the groove 22. The lower end of the telescopic column 232 is located inside the fixed cylinder 231, and the lower end of the telescopic column 232 is connected to the bottom of the fixed cylinder 231 by a spring. The upper end of the telescopic column 232 is fixed with the connecting frame 233. The upper end of the connecting frame 233 is connected to the support wheel 234 by a pin. The support wheel 234 can rotate around the pin. By setting the support wheel 234, it can be pushed into the groove 22 on the square plate 21 from one side, which plays a guiding role. Through the spring connection between the telescopic column 232 and the fixed cylinder 231, elastic limit is performed according to the width of the foam 4 and plastic sheet 5, which improves the versatility of use.

[0028] Furthermore, to ensure the alignment of the first positioning plate assembly 2 and the second positioning plate assembly 3, a guide mechanism 9 is provided between the first positioning plate assembly 2 and the second positioning plate assembly 3. The guide mechanism 9 is respectively located at the four corners of the first positioning plate assembly 2 and the second positioning plate assembly 3. The guide mechanism 9 includes a guide strip 91 and a C-shaped block 92. The C-shaped block 92 is fixed to the side of the square plate 21 in the first positioning plate assembly 2, and the guide strip 91 is fixed to the side of the square plate 21 in the second positioning plate assembly 3. The guide strip 91 is slidably connected in the C-shaped block 92. Through the sliding cooperation of the guide strip 91 and the C-shaped block 92, the foam 4 and the plastic plate 5 can be aligned, while ensuring the straightness of the plastic plate 5 when moving and pressing towards the foam 4.

[0029] In use: After applying glue to the surface of foam 4, push foam 4 into the groove 22 of the first positioning plate assembly 2 so that one side of foam 4 is in close contact with the surface of groove 22. The support wheels 234 located at the upper and lower ends of groove 22 are in contact with the upper and lower surfaces of foam 4 respectively. One end of foam 4 is in close contact with the closed end side of groove 22. In the same way, push the plastic plate 5 to be bonded into the groove 22 of the second positioning plate assembly 3. Then activate the pressing mechanism 6 to push the plastic plate 5 against foam 4 so that the two are tightly bonded.

[0030] This invention can align and press the foam 4 and plastic plate 5 together to avoid misalignment and improve the quality of sand mold use; by setting the guide mechanism 9, the alignment accuracy of the foam 4 and plastic plate 5 can be guaranteed, and misalignment can be avoided.
