Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for sand mixers, and particularly relates to a fixed support device for a resin sand mixer. Background Technique

[0002] A resin sand mixer is a mechanical device used in foundry enterprises to mix resin molding sand and core sand. It can achieve continuous operation and mix sand grains with sand mixing materials such as liquid curing agents and liquid resins evenly through high-speed rotating blades to produce resin self-hardening sand that meets the casting requirements.

[0003] During the sand mixing process, the mechanical operation will generate large vibrations and impact forces. Therefore, a fixed support base needs to be set at the bottom of the resin sand mixer, and the fixed support base can effectively absorb and disperse these forces to prevent the equipment from affecting the working efficiency and accuracy due to shaking or tilting. Before the existing resin sand mixers are used, the installation height of the fixed support base needs to be adjusted to adjust the installation height of the resin sand mixer to ensure the best matching relationship with other equipment on the production line. For example, the Chinese utility model patent with the publication number CN208906290U: A fixed support device for a foundry sand mixer. This application is provided with a support mechanism. When the sand mixer is placed on the second bottom plate, due to the action of gravity, the second bottom plate moves downward, the telescopic spring has elasticity, and the support mechanism has the effects of support and buffering and shock absorption. At the same time, the telescopic cylinder drives the piston rod to the bottom of the second bottom plate, and the telescopic cylinder and the piston rod play a supporting role. However, in the application process of this application, the telescopic cylinder is the main support member. As a movable part, the performance of the telescopic cylinder such as its sealing performance and wear resistance will gradually decrease over time and need to be maintained and replaced regularly. This not only increases the maintenance cost but also may increase the equipment failure rate due to improper maintenance, and it is easy to cause the resin sand mixer to suddenly become unstable when a failure occurs, resulting in the disconnection of the connection between the resin sand mixer and other equipment. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to make the technical means, creative features, achieved purposes, and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As Figures 1-5 shown, a fixed support device for a resin sand mixer provided by the present utility model includes a bottom plate 1. A plurality of support bases 2 are fixedly installed on the top of the bottom plate 1. One side of the top of the support base 2 is fixedly installed with a guide column 3. A supporting plate 4 is movably installed between the plurality of guide columns 3. A lifting ring 5 is fixedly installed at the center of the top of the supporting plate 4. A plurality of limiting mechanisms 6 are further provided on the supporting plate 4 located outside the guide column 3. The limiting mechanism 6 includes a fixed seat 7 and a plurality of clamping blocks 8. One side of the clamping block 8 is fixedly installed with a fixed shaft 9. The fixed seat 7 is fixedly installed on one side of the top of the supporting plate 4. The clamping block 8 is movably installed in the fixed seat 7 through the fixed shaft 9. A connecting plate 10 is movably connected between the plurality of fixed shafts 9.

[0022] As Figures 1-2 shown, a plurality of bases 11 are fixedly installed at the bottom of the supporting plate 4. The plurality of bases 11 are grouped in twos and arranged circumferentially along the contour of the supporting plate 4. A plurality of card slots 12 are formed on the outer side of the guiding column 3. The inner bottom of the card slot 12 is in an inclined shape. Through the arrangement of the guiding column 3 and the card slot 12, it is convenient for the supporting plate 4 to be adjusted up and down between the four guiding columns 3 through the fixing seat 7;

[0023] As Figures 3-5 shown, a jack 13 is formed in the fixing seat 7. A plurality of telescopic slots 14 are formed on the inner side of the jack 13. And three telescopic slots 14 are grouped as a set. The supporting plate 4 is inserted and installed on the four guiding columns 3. And the guiding column 3 also penetrates through the jack 13 in the fixing seat 7. The clamping block 8 is in a C-shaped structure. A rubber ring 15 is fixedly installed on the outer side of the fixing shaft 9 close to the clamping block 8. The clamping block 8 is inserted and installed in the telescopic slot 14. One side of the fixing shaft 9 passes through the through hole on the inner side of the telescopic slot 14 and extends to the outside of the fixing seat 7. A compression spring 17 is sleeved on the fixing shaft 9 between one side of the clamping block 8 and the inner side of the telescopic slot 14. Two pull rods 16 are fixedly installed on one side of the connecting plate 10. The connecting plate 10 is inserted and installed on one side of the three fixing shafts 9. A nut is also threadedly connected to the fixing shaft 9 on one side of the connecting plate 10. A plurality of clamping blocks 8 are inserted and installed in the fixing seat 7. And with the acting force of the compression spring 17, the clamping block 8 can reciprocally expand and contract on one side when the supporting plate 4 is lifted and be clamped into the corresponding card slot 12, so as to realize the real-time limit when the supporting plate 4 is lifted.

[0024] It should be noted that the present utility model is a fixing and supporting device for a resin sand mixer. When the supporting plate 4 is lifted, the supporting plate 4 can be lifted by binding the steel cable of the hoisting mechanism to the lifting ring 5, or the supporting plate 4 can be directly lifted manually. Thus, when the supporting plate 4 moves upward, the supporting plate 4 drives the four fixing seats 7 at the top to move up synchronously. And the two groups of clamping blocks 8 inside the fixing seat 7 reciprocally move in the corresponding telescopic slots 14 respectively by using the slopes at their tops and the slopes at the tops of the card slots 12. Therefore, when the supporting plate 4 moves upward, the supporting plate 4 can be limited from sinking by successively clamping the plurality of clamping blocks 8 into the corresponding card slots 12 on the outer side of the corresponding guiding columns 3. When the height adjustment of the supporting plate 4 is completed, the bottom of the resin sand mixer can be fixed to the supporting plate 4;

[0025] In addition, when it is necessary to lower the supporting plate 4, the two pull rods 16 on one side of the connecting plate 10 can be pulled, so that the connecting plate 10 pulls the three fixing shafts 9 in the same group to one side through the nuts. Then, the fixing shafts 9 drive the clamping blocks 8 to move into the telescopic grooves 14 and compress the compression springs 17 towards the inner side of the telescopic grooves 14, and the rubber ring 15 areas on the outer sides of the fixing shafts 9 are inserted into the through holes on the inner side of the telescopic grooves 14, thus realizing the limit of the clamping blocks 8 in the telescopic grooves 14. Then, the remaining clamping blocks 8 can be operated in the same way as above. Furthermore, the supporting plate 4 can be moved up and down on the four guide posts 3 through the four fixing seats 7.

[0026] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
