Description

Technical Field

[0001] The invention belongs to the technical field of iron mold sand-coated molding, and in particular relates to an iron mold sand-coated production line that is compatible with iron molds of different widths. Background Art

[0002] Sand-coated iron mold casting is a casting process in which a thin layer of molding sand is covered on the inner cavity of a metal mold (called an iron mold) to form a casting mold. The iron mold sand-coated process is used to produce ductile iron castings. The excellent performance of the product has been widely recognized by the industry and is a guarantee for achieving lightweight castings and replacing steel with iron.

[0003] At present, all product production lines are standardized automated production lines, which can ensure the automated and continuous production of such products. However, the molding line can only produce specific types of products and cannot take into account other types of products, especially products with large size differences. If a molding line is built alone, the cost is too high. At present, it is mainly divided into two major markets: host and maintenance. The maintenance market has many types of products and small quantities. If automatic lines are used for production, the advantages of automatic lines cannot be brought into play, which affects the production rhythm. At the same time, because there are many types of products, the width and size of the iron molds involved are also many, and the automatic line cannot be compatible with different iron molds.

[0004] The current molding lines are often only suitable for one width of iron molds and cannot meet the production of iron molds of different widths. Therefore, there is an urgent need for a molding line that can adapt to the production of iron molds of different widths.

[0005] Therefore, how to provide a molding line that can adapt to iron molds of different widths is a problem that those skilled in the art urgently need to solve. Summary of the invention

[0006] In view of this, the present invention provides a production line for sand coating of iron molds that is compatible with iron molds of different widths. It is compatible with iron molds of different widths and does not require a separate molding line to be designed for different products, thus saving costs and having strong versatility.

[0007] In order to achieve the above object, the present invention adopts the following technical solution: a production line for iron mold sand coating that is compatible with iron molds of different widths, comprising:

[0008] A pouring section, which is used to move the iron mold after the box is assembled and complete the pouring of the iron mold in the pouring section. The pouring section is provided with stepped rollers adapted to the iron molds of different widths in parallel, and the adjacent rollers are connected in series by transmission. The pouring section is provided with a power source for the transmission connection rollers;

[0009] A molding section, which is used for the sand-shooting molding process inside the iron mold. The molding section is arranged in parallel on one side of the pouring section. A molding machine, a box turner, a vibrating sand-falling machine and a box opener are connected to the molding section. The molding section includes two parallel wheel frames, on which a plurality of rollers for transporting the iron mold are arranged in parallel. The wheel frames are slidably connected to the molding section support seat and realize the width adjustment of the wheel frames. An adjustment mechanism for controlling the sliding of the wheel frames is provided on the support seat;

[0010] A transition section, which is located at one end of the casting section and the molding section and transitions the iron mold;

[0011] A connecting track is slidably connected with a transfer vehicle, and the connecting track is arranged at the other end of the pouring section and the molding section. The pouring section, the molding section, the transition transfer section and the connecting track constitute an iron mold circulation loop.

[0012] The beneficial effects of the present invention are as follows: the casting section and molding section of the product can adaptively transport iron molds of different widths according to different production needs to meet the use requirements. Different iron molds are used in the casting process of different types of products. During production, for different products, it is only necessary to replace the iron molds of appropriate widths. The stepped rollers on the casting section can be compatible with iron molds of different widths due to their own structural characteristics, thereby realizing the transportation of iron molds of different widths. Due to the sand shooting molding process, the wheel frames provided on the molding section are used to transport the iron molds. When replacing the iron molds, it is only necessary to change the widths of the two wheel frames to adapt to the width of the iron molds. There is no need to open a separate production line, thereby saving costs. The molding line of the present invention is a continuous loop molding line and can be used for continuous production.

[0013] Preferably, a plurality of rollers are rotatably connected in parallel on the frame of the casting section, and the ends of the plurality of rollers are fixedly connected with tower wheels or double-row wheels. Adjacent rollers are driven in series through the tower wheels or double-row wheels at the ends. A motor is fixedly connected to the frame of the casting section, and the output shaft of the motor is drivingly connected to the tower wheels or double-row wheels on the end rollers to establish a transmission relationship between the casting section rollers.

[0014] The technical effect produced thereby is that the roller is the basis of the line for transporting the iron mold, and the rotation of the roller is used to realize the forward transportation process of the iron mold. In the casting section, the distance is long, and the conventional method requires manual dragging of the iron mold forward, which wastes manpower and has high labor intensity. The present invention realizes the process of transporting the iron mold forward on the long-distance casting section by power connection of adjacent rollers without manual dragging.

[0015] Preferably, the outer side wall edges at both ends of the roller shaft are symmetrically provided with multiple steps corresponding to the axial direction of the roller shaft, and iron molds of different widths are adapted to enter the corresponding roller shaft steps and are sequentially transported to the downstream of the casting section.

[0016] The resulting technical effect is that the multi-step arrangement on the roller is used to adapt to the transportation of iron molds of different widths and improve the compatibility of the molding line.

[0017] Preferably, a slide groove is provided on the support seat of the shaping section, and the slide groove is opened in the width direction of the two wheel frames. The wheel frames are provided with vertical supports, and the vertical supports are provided with sliding parts matching the slide groove.

[0018] The technical effect produced by this is: the support seat is the installation basis of the shaping section wheel frame. It should be noted that in the specific implementation, there can be multiple groups of vertical supports on the wheel frame, and the sliding part on the vertical support cooperates with the slide groove to realize the stable movement of the wheel frame. It can be understood that the sliding part is a sliding clip used in conjunction with the slide groove, and the rail-type connection prevents the vertical support and the wheel frame from derailing.

[0019] Preferably, the adjusting mechanism includes an adjusting motor, an adjusting gear and a transmission rack. The adjusting motor is fixed in the middle of the support seat of the shaping section. The adjusting gear is connected to the output shaft of the adjusting motor. The transmission racks are arranged in pairs on the vertical supports of the two wheel frames in parallel. The transmission racks are meshed with the adjusting gears and are located at both ends of the adjusting gears. The rotation of the adjusting gears causes the transmission racks to drive the two wheel frames closer or farther away.

[0020] The resulting technical effect is that the adjusting mechanism drives the width adjustment of the two wheel frames, and the specific implementation form of the adjusting mechanism can be gear or rack drive.

[0021] Preferably, the adjustment mechanism is a telescopic rod, the fixed end and the telescopic end of the telescopic rod are respectively connected to the vertical supports of the two wheel frames, and the telescopic rod is a hydraulic rod or an electric rod.

[0022] The resulting technical effect is that another implementation form of the adjustment mechanism may be a telescopic rod, and in addition thereto, there may be other forms of power control.

[0023] Preferably, the base of the vibrating sand-falling machine connected to the shaping section is a stepped compatible base, the base of the vibrating sand-falling machine is provided with stepped grooves matching iron shapes of different widths, and the base is provided with a plurality of sand-falling holes.

[0024] The resulting technical effect is: the vibrating sand-falling machine base needs to shake off the molding sand inside the iron mold to facilitate the use of the next cycle of sand-covering molding. Due to the compatibility of the molding section with iron molds of different widths, it is necessary to ensure that the base is also suitable for iron molds of different widths. The present invention utilizes a stepped trough base to adapt to iron molds of different widths to meet production needs under different requirements.

[0025] Preferably, both ends of the transition transfer section are provided with a rotating table for connecting the transfer between the iron sections, and a conveying line is arranged on the rotating table.

[0026] The resulting technical effect is that the rotary table is used to transfer iron molds between different molding line segments to meet the automated production needs of the molding line.

[0027] Preferably, an iron mold cooling section is arranged between the shaping section and the connecting track, and an iron mold conveying line is arranged on the iron mold cooling section.

[0028] The technical effect produced thereby is: after pouring, the product is cooled and shaped in the cooling section, and then waits for the subsequent process of demoulding and removing materials. The present invention is a supporting use for the iron mold sand coating process production and can be produced continuously. BRIEF DESCRIPTION OF THE DRAWINGS
