Technical Field

[0001] This utility model belongs to the field of molding machine technology, and in particular relates to a special mold for an error-proof box for an automatic molding machine. Background Technology

[0002] An automatic molding machine is a type of mechanical equipment used in the metal casting industry. It is mainly used to automate the forming process of casting molds. In order to ensure the accuracy and consistency of the production process, reduce human error, and improve the overall production quality and efficiency, the automatic molding machine is equipped with a special mold with error prevention box.

[0003] Existing molds for error-proofing boxes typically employ a fixed structure design, with positioning dimensions matched to specific sand box specifications. However, in actual production, due to the diverse needs of casting products, the dimensions of the sand box, such as width and length, often need to be adjusted according to production requirements. When the sand box dimensions change, operators must replace the corresponding mold to accommodate the new sand box specifications. This process usually involves disassembling the original mold, installing the new mold, readjusting the positioning, and tightening, which is time-consuming and requires a high level of skill from the operators, thus reducing production efficiency.

[0004] To address these issues, we provide a special mold for error-proof boxes used in automatic molding machines. Utility Model Content

[0005] The purpose of this utility model is to provide a special mold for error-proof boxes for automatic molding machines. Through the cooperation of the detection mechanism and the positioning mechanism, the problem of the inflexibility of existing error-proof box special molds during use is solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a special mold for an error-proof box used in an automatic molding machine, comprising a base plate, a sand box on the top of the base plate, a detection mechanism on the top of the base plate, the detection mechanism comprising a detection box fixedly connected to the top of the base plate, detection frames respectively disposed around the detection box, and a marking plate fixedly connected to one side of the detection box; a positioning mechanism is provided at the bottom of the sand box, the positioning mechanism comprising a positioning column and a positioning rod respectively fixedly connected to the top of the base plate, and a first positioning groove and a second positioning groove respectively formed at the bottom of the sand box.

[0008] The present invention is further configured such that the detection mechanism includes a cylinder fixedly connected to the bottom of the detection box, an extrusion block fixedly connected to the output end of the cylinder, a movable block disposed on the top of the extrusion block, extrusion wheels disposed around the movable block, a movable plate fixedly connected to one side of the extrusion wheel, a vertical plate fixedly connected to the bottom of the movable plate, and a first spring fixedly connected to one side of the vertical plate.

[0009] The present invention is further configured such that the detection mechanism includes a guide rod disposed inside the detection box, a guide cylinder sleeved on the surface of the guide rod, and a second spring fixedly connected to the top of the guide cylinder.

[0010] The present invention is further configured such that a guide rod is fixedly connected to one side of the movable plate, and a limit plate is fixedly connected to one side of the guide rod.

[0011] The present invention is further configured such that a slider is fixedly connected to one side of the guide rod, and the slider is slidably connected to one side of the inside of the guide cylinder.

[0012] The present invention is further configured such that the testing frame is in close contact with the sand box, and the top of the base plate is provided with a mounting hole.

[0013] The present invention is further configured such that the movable block is in contact with the extrusion wheel, and the bottom of the movable block is in contact with the extrusion inclined block.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model uses a cylinder in the detection mechanism to drive the extrusion inclined block upwards, causing the movable plate and extrusion wheel to shift horizontally, thereby pushing the detection frame outwards. This movement provides variable installation space for the sand box, allowing the mold to adapt to sand boxes of different sizes. After the detection frame makes close contact with the sand box, the operator can quickly determine whether the sand box matches the specifications by using the standard size markings on the marking plate. This design solves the problem of traditional fixed molds being unable to be flexibly adjusted, significantly improving production efficiency while reducing the skill requirements for operators. The positioning pins and positioning rods in the positioning mechanism are respectively adapted to the first and second positioning grooves at the bottom of the sand box, ensuring the correct installation direction of the sand box. The differentiated design of the positioning pins and positioning rods avoids incorrect orientation during sand box installation. The detection frame limits the sand box during the resetting process, further preventing installation deviations. This dual positioning mechanism effectively reduces production problems caused by human error and improves the precision and consistency of casting molds.

[0016] 2. This utility model utilizes the first and second springs in the detection mechanism to assist the movable plate and guide rod in resetting, ensuring the detection frame can close stably after detection. The cooperation of the guide rod and guide cylinder prevents the movable block from shifting, while the guide rod and limit plate restrict the movement stroke of the movable plate, preventing the detection frame from over-expanding or detaching from the detection box. These structural designs enhance the stability and durability of the mold, extending the service life of the equipment.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
