[0002] A molding machine refers to a casting equipment used to make sand molds. Its main functions are: filling sand, filling loose molding sand into the sand box; compacting the molding sand, making the loose molding sand in the sand box compact by different methods such as vibration, compaction, vibration pressure, and shot pressure, so that the sand mold has the necessary strength during the process of transportation and pouring. The sand box structure inside the molding machine refers to the box structure that can press the engineering sand into shape.
[0003] At present, the sand box structure of the molding machine on the market is mainly modified in terms of the compressive strength of the sand box. The existing sand box structure of the molding machine is generally composed of a sand box, a molding plate and a side support plate. After the sand box is filled with sand, the hydraulic system presses the side support plate and the sand box downward to press the engineering sand into shape. However, the existing side support plates are usually composed of fixed compressive alloy plates, which cannot perform buffering and shock absorption after the hydraulic system is pressed down. Long-term use will cause damage to the sand box. Therefore, a molding machine sand box structure is proposed that can buffer and absorb shock during hydraulic molding, reduce sand box damage, and is conducive to increasing the service life of the sand box.

It solves the problem that the existing side support plates are usually composed of fixed compression-resistant alloy plates, which cannot perform buffering and shock reduction after the hydraulic system is pressed down, and the sand box will be damaged after long-term use.
[0005] In order to achieve the above-mentioned purpose of being able to buffer and reduce shock during hydraulic forming, reduce sand box damage, and be beneficial to improving the service life of the sand box, the utility model provides the following technical solutions: a molding machine sand box structure, including a molding machine forming plate, a sand box body is arranged inside the molding machine forming plate, a side support plate is fixedly installed on the top of the molding machine forming plate, and a buffer mechanism is arranged inside the side support plate;
[0006] The buffer mechanism includes a fixed mother plate, a hydraulic shock absorber, a pressure plate, a card plate, a spring damper, a slider, a limit block and a rubber strip.

[0007] Furthermore, a card slot matched with the card plate is formed at the bottom of the side support plate, and a fixing slot matched with the two rubber strips is formed at the bottom of the side support plate.
[0008] Furthermore, two movable blocks are fixedly mounted on the outside of the fixed mother plate, and sliding grooves adapted to the two movable blocks are provided on the outside of the molding plate of the molding machine.
[0009] Furthermore, a guide rail adapted to the two sliding blocks is fixedly mounted on the outside of the side support plate, and the two guide rails are symmetrically arranged on the left and right.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0013] The sand box structure of the molding machine is provided with a buffer mechanism. When it is necessary to buffer the falling vibration pressure, the side support plate bears the pressure and presses the rubber strip downward. The rubber strip is squeezed and deformed to relieve part of the pressure. Then the side support plate contacts the clamping plate through the spring damper. The spring damper buffers part of the pressure. The clamping plate and the pressure-bearing plate continue to press downward. The pressure-bearing plate and the slide block are pressed downward along the guide rail. The hydraulic shock absorber bears the subsequent pressure. Through the triple buffering pressure, the vibration force is reduced when the sand box body is pressed, and the internal engineering sand is slowly compressed to form, so as to avoid vibration damage to the sand box body. The buffer mechanism can buffer and reduce shock, reduce sand box damage, and is conducive to increasing the service life of the sand box. BRIEF DESCRIPTION OF THE DRAWINGS

By setting the card slot, the card plate 404 can be limited so that it can only move up and down, which is beneficial for the spring damper 405 to buffer the pressure. By setting the fixing slot, compression space can be provided to the two rubber strips 408, which is beneficial for buffering and shock absorption.
[0022] In the case implementation, the outside of the side support plate 3 is fixedly installed with a guide rail compatible with the two sliders 406, and the two guide rails are symmetrically arranged on the left and right. By setting up the two guide rails, the slider 406 can move up and down smoothly.

The rubber wheels can prevent side collisions and avoid damaging the side support plate 3.

[0030] To sum up, the sand box structure of the molding machine is provided with a buffer mechanism 4. When it is necessary to buffer the falling vibration pressure, the side support plate 3 bears the pressure and presses the rubber strip 408 downward. The rubber strip 408 is squeezed and deformed to relieve part of the pressure. Then the side support plate 3 contacts the card plate 404 through the spring damper 405. The spring damper 405 buffers part of the pressure. The card plate 404 and the pressure plate 403 continue to press downward.
