Description

Technical Field

[0001] This utility model relates to the field of molding machine technology, specifically a molding machine for metal castings that can be efficiently formed. Background Technology

[0002] A molding machine is a casting equipment used to manufacture sand molds. Its main functions are: filling sand, which involves filling loose molding sand into the sand box; and compacting the molding sand, which involves compacting the loose molding sand in the sand box through different methods such as vibration, pressing, vibration pressure, and injection pressure, so that the sand mold has the necessary strength during handling and pouring.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN221209800U) discloses a molding machine for efficient forming of metal castings. The machine includes a base frame, a device frame fixedly connected to the base frame, an extrusion assembly mounted on the device frame, a collection assembly mounted on the surface of the device frame, and an assembly located inside the device frame. The collection assembly includes a collection groove formed on the inner surface of the device frame, a sliding groove on the inner surface of the device frame, and a rotating frame slidably connected within the sliding groove. A transmission gear is arranged around the side end face of the rotating frame, and a through hole is formed on the side surface of the device frame. This technical solution solves the problem of certain defects in traditional molding machines for castings, where residual sand material remains on the surface of the workpiece after use, resulting in wasted costs.

[0004] Although the aforementioned patent can collect residual sand, its discharge structure collects sand through a pipe, which not only affects the smoothness of sand discharge but also easily causes sand discharge blockage, thus affecting the convenience of sand collection and processing.

[0005] Therefore, this utility model provides a molding machine for metal castings that can be efficiently formed, in order to solve the above problems. Utility Model Content

[0029] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figure 1-5As shown, this utility model provides a molding machine for efficient forming of metal castings, including a frame 1, a column 11 fixedly connected to the top of the frame 1, and a worktable 12 fixedly connected to the top of the column 11; a material collection trough 2, which is sleeved on the outside of the worktable 12, and the top of the material collection trough 2 has an integrally formed groove ring 21, and the lowest point of the material collection trough 2 has an arc-shaped discharge port; a material collection cylinder 3, which is set below the material collection trough 2, and the bottom of the material collection cylinder 3 is provided with universal wheels 31; and a cleaning assembly 4, which is connected between the frame 1 and the material collection trough 2, and is used for rotating and cleaning the inner wall of the material collection trough 2. Through the arrangement of the material collection trough 2 and the material collection cylinder 3, the worktable can be cleaned. The residual sand on the workbench 12 is guided and collected, and the sand can be quickly dropped and collected, avoiding blockage during the collection process and improving the collection efficiency. The push plate 14 is moved by the operation of the first cylinder 13, which pushes the residual sand on the surface of the workbench 12 to fall into the inside of the collection trough 2. At the same time, a guide sleeve can be set inside the U-shaped structure of the collection cylinder 3, and a plug-in shaft is set on the outer wall of the column 11 corresponding to the guide sleeve. When the collection cylinder 3 is pushed to the bottom of the collection trough 2, the plug-in cooperation of the guide sleeve and the plug-in shaft can achieve auxiliary positioning of the collection cylinder 3, ensuring the stability of the collection of the collection cylinder 3 and the accuracy of the collection of the sand falling into the collection trough 2.

[0031] Furthermore, a first cylinder 13 and a second cylinder 15 are fixedly connected to the outer wall of the frame 1. A push plate 14 is fixedly connected to the lifting end of the first cylinder 13, and a pressure plate 16 is fixedly connected to the lifting end of the second cylinder 15. When the first cylinder 13 is working, the push plate 14 is moved back and forth, which pushes the residual sand on the upper surface of the workbench 12 to fall off. At the same time, the operation of the second cylinder 15 drives the pressure plate 16 to move up and down, which can cooperate with the sand box to achieve compaction.

[0032] Furthermore, the lower surface of the push plate 14 is above the upper surface of the workbench 12, and a rubber pad is provided on the lower surface of the push plate 14. Both ends of the push plate 14 are inclined inward. Through the contact between the lower surface of the push plate 14 and the upper surface of the workbench 12, the push plate 14 can completely push away the sand material remaining on the upper surface of the workbench 12.

[0033] Furthermore, the cross-section of the collecting trough 2 is V-shaped, and the inside of the groove ring 21 is provided with a rotating groove. The top inner diameter of the groove ring 21 is chamfered. The V-shaped structure of the collecting trough 2 can quickly guide the collected sand, allowing it to slide and fall towards the center. Then, it falls into the collecting cylinder 3 through the discharge port. The collecting cylinder 3 is U-shaped, which can be directly pushed to the bottom of the collecting trough 2 to collect the sand.

[0034] Furthermore, the cleaning component 4 includes a servo motor 41, with a support frame 45 fixedly connected to the outer wall of the servo motor 41. The support frame 45 is fixedly connected to the outer wall of the frame 1. A gear 42 is fixedly connected to the output end of the servo motor 41. A gear ring 43 meshes with the outer side of the gear 42. A scraper 44 is fixedly connected to the inner wall of the gear ring 43. The gear ring 43 is rotatably disposed inside the rotating groove of the slot ring 21, and the inner diameter of the gear ring 43 is smaller than the inner diameter of the slot ring 21. The scraper 44 rotates and adheres to the inner wall of the collection trough 2. Driven by the servo motor 41, the gear 42 is driven to rotate. Furthermore, the scraper 44 is driven to rotate through the meshing of the gear ring 43. While the scraper 44 rotates, it can rotate and scrape the inner wall of the collection trough 2, thereby cleaning the inner wall of the collection trough 2 and reducing the residue of sand.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
