The sliding components are symmetrically installed on the left and right inner walls of the base frame, and multiple sets of the sliding components are evenly distributed at equal intervals along the height direction of the base frame. The first limiting components are symmetrically installed at the front and rear ends of the sliding components. Several sets of support components are provided, and the support components are connected to the sliding components installed on the left and right inner walls of the base frame. The support components are also equipped with second limiting components.

[0009] The first and second limiting components have the same structure and function, only their installation positions are different.

[0010] The front and rear ends of the base frame are symmetrically equipped with auxiliary feeding mechanisms for use with sliding components to assist the operator in picking up the shell mold;

[0011] Furthermore, the auxiliary feeding mechanism is in a folded and retracted state when the shell mold is not being picked up, and is pulled down to unfold when the shell mold needs to be picked up.

[0012] Furthermore, the sliding assembly includes a fixing plate, which is fixedly installed on the inner wall of the base frame, and a T-shaped sliding groove is provided on the fixing plate;

[0013] Furthermore, the supporting component includes guide wheels, a storage plate, and an insert plate. The left and right ends of the insert plate are slidably connected to the T-shaped groove for limiting. Multiple guide wheels are symmetrically and rotatably installed on the left and right inner walls of the insert plate, and the guide wheels are evenly distributed linearly and at equal intervals along the width direction of the insert plate. A sliding groove is provided at the inner bottom of the insert plate. The lower ends of the left and right ends of the storage plate are slidably connected to the guide wheels. The lower end of the storage plate is slidably connected to the sliding groove.

[0015] The baffle of the first limiting component is rotatably mounted on one end of the fixed plate, and the baffle of the second limiting component is rotatably mounted on one end of the insert plate; a torsion spring is wound on the rotating shaft of the baffle.

[0016] Furthermore, one end of the torsion spring of the first limiting component is fixedly connected to the baffle, and the other end of the torsion spring of the first limiting component is fixedly connected to the fixing plate; one end of the torsion spring of the second limiting component is fixedly connected to the baffle, and the other end of the torsion spring of the second limiting component is fixedly connected to the insert plate.

[0017] Furthermore, the baffles of the first limiting component and the second limiting component are kept perpendicular by the torsion spring; and at this time, the baffle of the first limiting component is in contact with one end of the insert plate; the baffle of the second limiting component is in contact with one end of the storage plate.

[0018] Furthermore, the auxiliary feeding mechanism includes a first connecting rod, a second connecting rod, a support rod, support guide wheels, support feet, locking plates, and limiting rods.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0031] In some embodiments, please refer to the accompanying drawings. Figures 1-5 A shell mold material rack that is easy to assemble and disassemble includes a base frame 1, a bidirectional pull-out mechanism 2, and an auxiliary feeding mechanism 3. The base frame 1 is internally equipped with the bidirectional pull-out mechanism 2 for easy handling of the shell mold. The bidirectional pull-out mechanism 2 includes a sliding component 21 that is easy to pull out, a first limiting component, a second limiting component, and a supporting component 23 for storing the shell mold. The sliding components 21 are symmetrically installed on the left and right inner walls of the base frame 1, and multiple sets of the sliding components 21 are evenly distributed at equal intervals along the height direction of the base frame 1. The first limiting components are symmetrically installed at the front and rear ends of the sliding components 21. Several sets of supporting components 23 are provided, and the supporting components 23 are connected to the sliding components 21 installed on the left and right inner walls of the base frame 1. The supporting components 23 are also equipped with second limiting components.

[0032] The first and second limiting components have the same structure and function, only their installation positions are different.

[0033] The front and rear ends of the base frame 1 are symmetrically equipped with auxiliary feeding mechanisms 3 for use with the sliding assembly 21 to assist the operator in picking up the shell mold;

[0034] The auxiliary feeding mechanism 3 is in a folded and retracted state when the shell mold is not being picked up, and is in an unfolded state when the shell mold needs to be picked up;

[0035] In this invention, the auxiliary feeding mechanism 3 is pulled down to unfold, and then the second limiting component releases the lock on the bearing component 23, pulling the bearing component 23 outward. At this time, the outer end of the bearing component 23 moves onto the auxiliary feeding mechanism 3 and is supported by it. The shell mold can then be retrieved or placed at a deeper position on the bearing component 23. By reducing the number of bearing components 23 installed, the height of the base frame 1 is increased, allowing the base frame 1 to hold larger shell molds. This can be achieved through the sliding component 21. Pulling the support component 23 from both the front and rear directions facilitates the retrieval or placement of the shell mold at a deeper level within the support component 23, improving the convenience of the material rack. Adjusting the number of support components 23 installed according to the shape of the shell mold changes the layer height of the base frame 1, meeting the storage needs of shell molds of different shapes. The structure is simple, easy to disassemble and install, and has a low cost, improving the convenience and practicality of the material rack. Furthermore, the auxiliary unloading mechanism 3 reduces the probability of the material rack tipping over when the support component 23 is pulled out, and reduces the space occupancy rate, further enhancing the practicality of the device.

[0036] The sliding assembly 21 includes a fixing plate 211, which is fixedly installed on the inner wall of the base frame 1, and a T-shaped sliding groove 212 is provided on the fixing plate 211.

[0037] The supporting component 23 includes guide wheels 231, a storage plate 233, and an insert plate 234. The left and right ends of the insert plate 234 are slidably connected to the T-shaped sliding groove 212. Multiple guide wheels 231 are symmetrically and rotatably mounted on the left and right inner walls of the insert plate 234, and the guide wheels 231 are evenly distributed linearly and at equal intervals along the width direction of the insert plate 234. A sliding groove 232 is provided at the inner bottom of the insert plate 234. The lower ends of the left and right ends of the storage plate 233 are tumbledly connected to the guide wheels 231. The lower end of the storage plate 233 is slidably connected to the sliding groove 232.

[0038] The first limiting component is symmetrically installed at the front and rear ends of the fixed plate 211; the second limiting component is symmetrically installed at the front and rear ends of the insert plate 234; both the first limiting component and the second limiting component are composed of a baffle 221 and a torsion spring 222.

[0039] The baffle 221 of the first limiting component is rotatably mounted on one end of the fixed plate 211, and the baffle 221 of the second limiting component is rotatably mounted on one end of the insert plate 234; a torsion spring 222 is wound on the rotating shaft of the baffle 221.

[0040] Furthermore, one end of the torsion spring 222 of the first limiting component is fixedly connected to the baffle 221, and the other end of the torsion spring 222 of the first limiting component is fixedly connected to the fixing plate 211; one end of the torsion spring 222 of the second limiting component is fixedly connected to the baffle 221, and the other end of the torsion spring 222 of the second limiting component is fixedly connected to the insert plate 234.

[0041] The torsion spring 222 keeps the baffle 221 of the first limiting component and the baffle 221 of the second limiting component in a perpendicular state; and at this time, the baffle 221 of the first limiting component is in contact with one end of the insert plate 234; and the baffle 221 of the second limiting component is in contact with one end of the storage plate 233.

[0042] The auxiliary feeding mechanism 3 includes a first connecting rod 31, a second connecting rod 32, a support rod 33, support guide wheels 34, support feet 35, locking plates 36, and limiting rods 38. The first connecting rod 31 is symmetrically hinged to the upper left and right sides of one end of the base frame 1, and the second connecting rod 32 is symmetrically hinged to the lower left and right sides of one end of the base frame 1. The outer ends of the first connecting rod 31 and the second connecting rod 32 are hinged to the support rod 33. Multiple support guide wheels 34 are rotatably mounted on the support rod 33, and the number of support guide wheels 34 is the same as the number of fixed plates 211. The support feet 35 are fixedly mounted on the lower end of the support rod 33. Two locking plates 36 are rotatably mounted on the outer end of the support rod 33, and the locking plates 36 are provided with locking arc grooves 37 that cooperate with the limiting rods 38. Limiting rods 38 are symmetrically mounted on the upper and lower sides of the left and right ends of the base frame 1. The locking arc grooves 37 are engaged with the limiting rods 38.

[0043] In this invention, when the shell mold is not being removed, the locking arc groove 37 is engaged with the limiting rod 38. At this time, the first connecting rod 31 and the second connecting rod 32 are both tilted upwards and folded in, and the support rod 33 is in a vertical state. When the shell mold needs to be removed, the locking plate 36 on the front or rear side of the base frame 1 is rotated outwards, causing the locking arc groove 37 to separate from the limiting rod 38. Then, the support rod 33 is pulled downwards, causing the first connecting rod 31 and the second connecting rod 32 to rotate downwards until the lower end of the support foot 35 contacts the ground. At this time, the first connecting rod 31 and the second connecting rod 32 are in a horizontally extended state, and the support rod 33 remains in a vertical state. Furthermore, the upper end of the support guide wheel 34 provided on the support rod 33 corresponds to the lower end of the storage plate 233.

[0044] Then, rotate the baffle 221 on the second limiting component to release the lock on the storage plate 233. Pull the storage plate 233 outward, and the storage plate 233 will move outward along the guide wheel 231 and the sliding groove 232. During the outward movement, the storage plate 233 will continuously press down on the baffle 221. The front end of the storage plate 233 will continue to move outward along the support guide wheel 34 and be supported by the support guide wheel 34. Then, the shell mold can be taken out or placed on the storage plate 233. After the shell mold is taken out or placed, push the storage plate 233 to reset, and the torsion spring 222 will drive the baffle 221 to return to its original position, thus locking the storage plate 233. Then, push the support rod 33 upward, and the support rod 33 will drive the first connecting rod 31 and the second connecting rod 32 to rotate upward. Then, rotate the locking plates 36 on both sides so that the locking arc groove 37 on the locking plate 36 can engage with the limiting rod 38.

[0045] When the rack needs to store some large shell molds, rotate the baffle 221 of the first limiting component to release the lock on the insert plate 234, and then pull the insert plate 234 outward to move the storage plate 233 outward together until the insert plate 234 is completely pulled out of the base frame 1, thereby increasing the shelf height of the rack.

[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
