Description

Technical Field

[0001] This utility model relates to the field of casting sand hopper equipment, and in particular to a sand hopper lifting device. Background Technology

[0002] Molten metal needs to be placed into a mold to solidify during casting. These molds are mostly made from foundry sand and a sand mold binder. A foundry sand hopper is a device used to hold this sand. Operators typically feed the foundry sand into the hopper through an open top via a conveyor belt. When the sand is needed, the operator opens the discharge valve at the bottom of the hopper, allowing it to tilt out from the bottom.

[0003] When foundry sand is needed, the discharge valve at the bottom of the traditional foundry sand hopper is opened, allowing the sand to flow out at an angle. However, this traditional method has many inconveniences in actual operation. For example, it is difficult to accurately control the flow rate and discharge position of the foundry sand, which cannot meet the diverse needs of foundry sand feeding in different production scenarios. Furthermore, unstable discharge during operation may lead to waste of foundry sand or affect the production quality of the mold. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model provides a sand hopper lifting device that can accurately and flexibly control the feeding of casting sand.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sand hopper lifting device includes a support frame, at least one lifting drive component, multiple guide rods, multiple guide sleeves, a feed pipe, and a sand hopper. The length of the support frame is defined as the transverse direction, the width of the support frame as the longitudinal direction, and the height of the support frame as the vertical direction. A collection trough is located in the transverse middle of the support frame. A discharge port communicating with the collection trough is provided on the support frame. A through hole is provided at the bottom of the collection trough. The feed pipe is located at the through hole. Each guide sleeve is located on the support frame and distributed on both sides of the collection trough. Each guide rod passes through a guide sleeve. The sand hopper is located at the lower end of each guide rod and has a feed inlet. The lower end of the feed pipe is connected to the feed inlet. The lifting drive component is located on the support frame, and its output end is connected to the sand hopper.

[0007] Furthermore, the bracket includes an upper side plate, a lower side plate, a left side plate, a right side plate, a front side plate, a rear side plate, and an inclined plate. The upper side plate has a rectangular through groove in its horizontal center. The left side plate, right side plate, front side plate, and rear side plate are respectively located on the side of the through groove, and their lower sides are respectively connected to the lower side plate. The left side plate, right side plate, front side plate, rear side plate, and lower side plate form a material collection trough. The inclined plate is located on the bottom surface of the material collection trough. The vertical height of the front side plate is smaller than that of the rear side plate, so that the inclined plate and the lower side of the front side plate form a discharge port.

[0008] Furthermore, each of the guide rods is provided with a limiting block at its upper end.

[0009] Furthermore, the lifting drive component is a hydraulic cylinder, a pneumatic cylinder, or an electric actuator.

[0010] Furthermore, the lifting drive component has a drive rod, the free end of which is provided with an external thread, and the upper end of the sand hopper is provided with a connecting seat, the connecting seat being provided with a threaded hole that is threadedly connected to the drive rod.

[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0017] The embodiment of this utility model is as follows:

[0018] refer to Figures 1 to 4 As shown, a sand hopper lifting device includes a support 1, two lifting drive components 2, four guide rods 3, four guide sleeves 4, a feed pipe 5, and a sand hopper 6. The length direction of the support 1 is defined as the transverse direction, the width direction as the longitudinal direction, and the height direction as the vertical direction. The support 1 has a collection trough 7 in the transverse middle. The support 1 is provided with a discharge port 8 communicating with the collection trough 7. The bottom of the collection trough 7 is provided with a through hole 9. The feed pipe 5 is located at the through hole 9. Each of the guide sleeves 4 is located on the support 1 and distributed on both sides of the collection trough 7. Each of the guide rods 3 passes through the guide sleeves 4. The sand hopper 6 is located at the lower end of each guide rod 3. The sand hopper 6 is provided with a feed port 10. The lower end of the feed pipe 5 is connected to the feed port 10. The lifting drive components 2 are located on the support 1, and the output end of the lifting drive component 2 is connected to the sand hopper 6.

[0019] This sand hopper lifting device, through the arrangement of a bracket 1, lifting drive component 2, guide rods 3, guide sleeves 4, feed pipe, and sand hopper 6, utilizes the lifting drive component 2 to precisely control the lifting position of the sand hopper 6, thereby accurately controlling the discharge position of the casting sand and meeting the diverse needs of casting mold making for different casting sand placement positions. Furthermore, multiple guide rods 3 are respectively inserted into the guide sleeves 4 distributed on both sides of the collecting trough 7, providing stable guidance for the lifting of the sand hopper 6, ensuring that the sand hopper 6 does not deviate during the lifting process, guaranteeing the stability of the discharge, and improving the manufacturing quality of the casting mold. Simultaneously, the overall structure is compact, with each component working in concert, achieving precise casting sand dispensing within a limited space, saving production space, reducing equipment manufacturing costs, and the included collecting trough 7 and discharge port 8 can collect and discharge leaked casting sand during the sand hopper loading process, enabling reuse and improving ease of use.

[0020] Specifically, the bracket 1 includes an upper side plate 11, a lower side plate 12, a left side plate 13, a right side plate 14, a front side plate 15, a rear side plate 16, an inclined plate 17, and a protective cover 18. A rectangular through groove 20 is formed in the middle of the upper side plate 11. The left side plate 13, right side plate 14, front side plate 15, and rear side plate 16 are respectively located on the sides of the through groove 20, and their lower sides are respectively connected to the lower side plate 12. A material collection trough 7 is formed by the left side plate 13, right side plate 14, front side plate 15, rear side plate 16, and lower side plate 12. The inclined plate 17 is located on the bottom surface of the material collection trough 7. The vertical height of the front side plate 15 is smaller than the vertical height of the rear side plate 16, such that the inclined plate 17 and the lower side plate 15 are aligned. A discharge port 8 is formed on the side. The protective cover 18 is located on the lateral sides of the upper side plate 11 and the lower side plate 12, and covers the outside of the lifting drive component 2. The side plates form a collection trough 7. The inclined plate 17 and the vertical height of the front side plate 15 are smaller than that of the rear side plate 16, so that the inclined plate 17 and the lower side of the front side plate 15 naturally form the discharge port 8. This structure is conducive to the concentrated collection of casting sand in the collection trough 7 and can be smoothly discharged from the discharge port 8, improving the discharge efficiency. The side plates are connected to form a stable frame structure, which enhances the overall strength and stability of the support 1, can bear the weight of the sand hopper 6 and the internal casting sand, ensures the reliability of the equipment during long-term use, and reduces the probability of equipment failure.

[0021] Furthermore, each of the guide rods 3 is provided with a limiting block 21 at its upper end. When the sand bucket 6 rises to a certain height under the action of the lifting drive component 2, the limiting block 21 can prevent the guide rod 3 from coming out of the guide sleeve 4, thereby avoiding equipment damage and safety accidents caused by the guide rod 3 coming out, and improving the safety of equipment use.

[0022] Meanwhile, the lifting drive component 2 is a hydraulic cylinder, a pneumatic cylinder, or an electric actuator, preferably a pneumatic cylinder, which offers fast response and sensitive action. The lifting drive component 2 has a drive rod with an external thread 22 at its free end. The upper end of the sand hopper 6 has a connecting seat 23 with a threaded hole for threaded connection to the drive rod, achieving a stable connection between the lifting drive component 2 and the sand hopper 6. This threaded connection method is simple and reliable, capable of withstanding large tensile and torque forces, ensuring that the connection will not loosen or detach during the lifting of the sand hopper 6, guaranteeing the normal operation of the equipment. The threaded connection method facilitates installation and disassembly by operators. When the equipment needs maintenance, component replacement, or debugging, the lifting drive component 2 can be quickly and easily separated or reconnected to the sand hopper 6, improving equipment maintenance efficiency, reducing downtime, and thus increasing production efficiency.
