Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, and more specifically to a numerical control device for casting parts. Background Art

[0002] Parts casting, also known as casting, is a process of melting metal or non-metallic materials and pouring them into a pre-designed mold to form the desired parts or products after cooling and solidification. This process is widely used in various industries, especially in the field of mechanical manufacturing, to produce metal parts of various complex shapes and structures.

[0003] The shortcomings of existing CNC equipment for casting parts:

[0004] First, during the casting process of parts, in order to ensure the molding of materials, the two molds need to be clamped and fixed to each other. However, when clamping the existing molds, the two molds are generally fixed manually by bolts. This fixing method will result in insufficient clamping force. During the casting process, the insufficient force of the mold will cause the cast parts to shift or deform.

[0005] Second, the existing CNC equipment for casting parts generally directly pours the stock liquid into the mold during use. However, the surface temperature of the mold is low. After the stock liquid is poured, defects such as cold shut, incomplete pouring, inclusions, and air holes will appear on the back of the mold, which results in poor quality of the cast parts. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the utility model provides a numerical control device for casting parts to solve the problems existing in the above-mentioned background technology.

[0007] The utility model provides the following technical solution: a CNC device for casting parts, comprising an equipment box, pneumatic rods are fixedly connected to both sides of the bottom of the inner surface of the equipment box, a telescopic rod is movably connected to the bottom of the pneumatic rod, a block is fixedly connected to the bottom of the telescopic rod, a built-in groove is provided on the inner surface of the block, a threaded rod is provided in the built-in groove, a moving block is movably connected to the outer surface of the threaded rod, a connecting rod is fixedly connected to the bottom of the moving block, a bottom box is fixedly connected to the bottom of the equipment box, a heating block is fixedly connected to the front end of the inner surface of the bottom box, a partition is provided on the back of the heating block, and a scraper is movably connected to the back of the partition;

[0009] Furthermore, a bellows is fixedly connected to the front of the bottom box, a fan is fixedly connected to the middle of the bellows, a heating block is provided on the back of the bellows, a collecting trough is provided inside the bottom box, a scraper is movably connected to the inner surface of the collecting trough, and a pull rod is fixedly connected to one side of the scraper.

[0010] Furthermore, a square groove is provided on one side of the top of the block, a movable groove is provided on the bottom of the block, a movable block is movably connected to the inner surface of the movable groove, a thread is provided on the inner surface of the movable block and is adapted to the threaded rod, and a transmission belt is provided on the inner surface of the square groove.

[0011] Furthermore, a pouring box is fixedly connected to the top of the equipment box, a transmission pipe is fixedly connected to the bottom of the pouring box, a switch valve is fixedly connected to the outer surface of the transmission pipe, a pouring head is fixedly connected to the bottom of the transmission pipe, and a pouring port is provided at the bottom of the pouring head.

[0012] Furthermore, the length of the threaded rod is sixty centimeters, and the length of the moving block is five centimeters.

[0013] Technical effects and advantages of the utility model:

[0014] 1. When the motor of the utility model is started, the first transmission wheel starts to rotate, and when the first transmission wheel starts to rotate, the transmission belt starts to move, and then the second transmission wheel starts to rotate and the threaded rod installed on the second transmission wheel starts to rotate. At this time, the moving block starts to move on the threaded rod and drives the middle part of the connecting rod box equipment box to start moving. Then the two mold boxes are closed, and the original liquid is poured into the pouring port by opening the switch valve to complete the casting of the parts. The mold box is effectively pressed during the casting process to improve the accuracy and quality of the casting and enhance production safety.

[0015] 2. When the utility model is used, the heating block is moved, and then the pneumatic rod is started to move the telescopic rod downward to finally move the mold box into the collecting tank, and then the fan is started, and the fan blows air into the equipment box to transfer the heat on the heating block to the collecting tank, so that the mold box is heated. By heating the mold box in advance, the mold box can reach a suitable working temperature faster, thereby shortening the production cycle, ensuring that the metal material solidifies quickly and evenly in the mold box and reducing the appearance of pores.

[0016] 3. After the operation of the utility model is completed, a small amount of raw liquid will drip into the collection tank. At this time, the pull rod is pushed to move the scraper in the collection tank to scrape off the solidified raw liquid, which is conducive to the recycling and reuse of the scraped solidified raw liquid, avoiding the waste of materials and maintaining the cleanliness of the equipment.
