Description

Technical Field

[0001] This utility model relates to the field of casting technology, specifically to a continuous sand-adding device for casting. Background Technology

[0002] Casting is one of the earliest metal heat treatment techniques mastered by humankind, with a history of approximately 6,000 years. China entered its golden age of bronze casting around 1700-1000 BC, achieving a remarkably high level of craftsmanship. Casting involves pouring molten metal into a cavity conforming to the shape of the part, allowing it to cool and solidify to obtain the part or blank. The material being cast is often a metal that was originally solid but heated to a molten state (e.g., copper, iron, aluminum, tin, lead), while the mold material can be sand, metal, or even ceramic. Different methods are used depending on the requirements. Sand addition is a crucial step in the casting process, especially in precision casting, where it plays a vital role. It is used not only for mold making but also in the production of various power machinery, lifting and transport machinery, agricultural machinery, metallurgical and mining machinery, and chemical machinery.

[0003] However, existing continuous sand feeding devices for casting have the following disadvantages:

[0004] (1) Existing continuous sand feeding devices for casting are prone to blockage during the sand discharge process. When in use, large sand particles are often present in the casting sand, causing blockage at the sand discharge port.

[0005] (2) The existing continuous sand-adding device for casting has a weak adjustment function. When adding sand to different castings, the required height is different, which makes it difficult to add sand and is not conducive to use. Utility Model Content

[0013] Preferably, a protective layer is fixedly connected to the side wall of the guide cylinder, and a control panel is fixedly connected to the side wall of the protective layer.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This continuous sand feeding device for casting is equipped with a motor B, a drive gear, etc. In use, the motor B drives the drive gear to rotate, which in turn drives the driven gear to rotate. The rotation of the driven gear causes the spiral pusher plate to rotate, thereby breaking up large sand particles in the casting sand. At the same time, the spiral pusher plate pushes the casting sand into the sand discharge pipe, avoiding the large accumulation of casting sand inside the guide cylinder, which would cause difficulties in sand discharge.

[0016] This continuous sand-adding device for casting is equipped with a motor A, a winding shaft, etc. In use, the motor A drives the winding shaft to rotate, which in turn drives the sand-adding device to move up and down, thereby adjusting the height of the device to adapt to different sand-adding requirements, greatly enhancing its practicality and making the device more convenient to use.

The driven gear 22 is internally connected to an installation ring 26, and a spiral pusher plate 23 is fixedly connected to the bottom of the installation ring 26. Through a motor B20, a drive gear 21, etc., in use, the motor B20 drives the drive gear 21 to rotate, which in turn drives the driven gear 22 to rotate. The rotation of the driven gear 22 causes the spiral pusher plate 23 to rotate, thereby breaking up large sand particles in the foundry sand. Simultaneously, the spiral pusher plate 23 pushes the foundry sand into the sand discharge pipe 4, preventing the foundry sand from accumulating excessively inside the guide cylinder 14 and causing difficulties in sand discharge. Through a motor A8, a winding shaft 9, etc., in use, the motor A8 drives the winding shaft 9 to rotate, causing the sand adding device to move up and down, thereby adjusting the height of the device to adapt to different sand adding requirements, greatly enhancing its practicality and making the device more convenient to use.

[0025] In this embodiment, preferably, a plurality of reinforcing plates 2 are fixedly connected to the side wall of the support frame 1, and an anti-slip pad 19 is fixedly connected to the bottom of the support frame 1.

[0026] In this embodiment, preferably, a mounting bracket 25 is fixedly connected to the side wall of the guide tube 14, and an ultrasonic oscillator 24 is fixedly connected to the side wall of the mounting bracket 25. By setting the ultrasonic oscillator 24, the side wall of the guide tube 14 vibrates at high frequency, thereby accelerating the discharge speed of casting sand in the guide tube and avoiding blockage.

[0027] In this embodiment, preferably, a flow limiting valve 15 is fixedly connected to the side wall of the sand discharge pipe 4. The flow limiting valve 15 allows the staff to easily adjust the flow rate of the sand in the sand discharge pipe 4.

Simultaneously, the spiral pusher plate 23 pushes the casting sand into the sand discharge pipe 4, preventing sand from accumulating excessively inside the guide cylinder 14 and causing discharge difficulties. Through the inclusion of motor A8 and a winding shaft 9, the device is raised and lowered during operation, adjusting its height to meet different sand-adding requirements, greatly enhancing its practicality and making it more convenient to use. The reinforcing plate 2 improves the stability of the support frame 1, and the anti-slip pad 19 ensures the stability of the heat shrink film inspection machine. Throughout the operation, by reducing the friction between the equipment and the ground, the stability of the equipment is maintained and its service life is extended. The ultrasonic oscillator 24 causes the side wall of the guide cylinder 14 to vibrate at high frequency, thereby accelerating the discharge speed of the casting sand in the guide cylinder and preventing blockage. The side wall of the sand discharge pipe 4 is fixedly connected to a flow limiting valve 15, which allows the operator to easily adjust the flow speed of the sand in the sand discharge pipe 4. The universal wheels 17 and anti-slip rods 18 make it easy to move and fix the casting mold 6, making the casting mold 6 more convenient to use. The side wall of the guide cylinder 14 is fixedly connected to a protective layer 12, and the control panel 13 is fixedly connected to the side wall of the protective layer 12.
