Description

Technical Field

[0001] The utility model relates to the technical field of casting production, in particular to a device for shaking off molding sand on the surface of a cast iron part. Background Art

[0002] Sand casting is one of the common methods for producing iron castings. Sand casting refers to the casting method of producing castings in sand molds. Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. Since the molding materials used in sand casting are cheap and easy to obtain, the mold is easy to manufacture, and it can adapt to the single-piece production, batch production and mass production of castings, it has long been the basic process in casting production.

[0003] After the sand casting is completed and the inside is cooled, the mold needs to be disassembled and the external molding sand needs to be broken and shaken off to obtain the internal casting. During the existing casting production, workers need to hold the casting and drop it, relying on the shaking generated by the drop and the inertia of the molding sand to achieve the effect of loosening and shaking off the molding sand. The mold sand shaken off is relatively scattered, and the shaking position needs to be changed. The shaken molding sand is inconvenient to collect and it is difficult to control the drop height, and multiple castings cannot be shaken off at the same time. Utility Model Content

DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.

[0023] like Figure 1-4 The device shown is a device for shaking off the surface sand of a cast iron part, comprising a collecting box 1, a supporting rod 2, a motor 3, a connecting shaft 4, a flip plate 5, a supporting device 6, a hanging rod 7, a contact block 8 and a pressure device 9. The supporting rod 2 is fixedly arranged inside both sides of the collecting box 1, the motor 3 is installed on the outside of the supporting rod 2, the connecting shaft 4 is fixedly arranged at both ends of the flip plate 5, the supporting device 6 is installed on the outside of the supporting rod 2, the hanging rod 7 is clamped on the inside of the supporting rod 2, the contact block 8 is fixedly arranged at both ends of the hanging rod 7, the pressure device 9 is installed on the end of the supporting rod 2, the supporting device 6 comprises an oil cylinder 61, a connecting seat 62, a sliding seat 63, a guide rod 64 and a spring 65. The connecting seat 62 is fixedly arranged at the telescopic end of the oil cylinder 61, the sliding seat 63 is clamped on the inner side of the bottom of the connecting seat 62, the guide rod 64 is fixed to the back of the sliding seat 63, and the spring 65 is sleeved on the outside of the guide rod 64.

[0024] Specifically, the pressure-applying device 9 includes a mounting plate 91, a telescopic rod 92, a pressure rod 93 and a push block 94. The mounting plate 91 is fixedly arranged on the outer side of the support rod 2, the telescopic rod 92 is installed on the upper surface of the mounting plate 91, the pressure rod 93 is fixedly arranged on the telescopic end of the telescopic rod 92, and the push blocks 94 are fixedly arranged on the bottom of both ends of the pressure rod 93. The push blocks 94 are located on the outer side of the top of the sliding seat 63, and an inclined surface is provided on the outer side of the bottom of the push block 94. A slope matching therewith is provided on the inner side of the top of the sliding seat 63. One end of the guide rod 64 passes through and extends to the outer side of one side of the connecting seat 62, and a limiting piece is provided at its end. A spring 65 is provided between the back of the sliding seat 63 and the inner side of one side of the connecting seat 62. Guide blocks are provided on both sides of the contact block 8. A card groove matching the contact block 8 and the guide blocks on both sides thereof is provided inside the support rod 2. The bottom of one end of the contact block 8 contacts the inner side of the bottom of the sliding seat 63. A wedge-shaped surface is provided on one end of the top of the contact block 8, and an inclined surface matching therewith is provided on the bottom of one end of the sliding seat 63.

[0025] In this embodiment, the casting that needs to be treated with molding sand is first fixed in the suspension hole on the surface of the suspension rod 7 by a fixing clamping device, and then the oil cylinder 61 is controlled to rise, and the connecting seat 62 at the top of the oil cylinder 61 drives the sliding seat 63 to rise, so that the inner side of the bottom of the sliding seat 63 is clamped on the bottom of the contact block 8, so that the contact block 8 is lifted up by the lifting of the sliding seat 63. Since the contact block 8 is fixed at both ends of the suspension rod 7, the casting installed in the suspension hole on the surface of the suspension rod 7 will be lifted to a certain height by the oil cylinder 61.

[0026] Furthermore, the pressure-applying device 9 is operated to apply pressure to the pressure rod 93 from the top, so that the telescopic rod 92 installed on the top of the mounting plate 91 is compressed and contracted, and the pressure rod 93 moves downward, so that the inclined surface at one end of the bottom of the push block 94 contacts the slope on the inner side of the top of the sliding seat 63, and squeezes the sliding seat 63, causing it to move backward according to the slope of the slope, and applying pressure to the spring 65 at its tail end, causing it to contract, and the guide rod 64 moves backward. The guide rod 64 plays the role of installing the spring 65 and guiding the movement of the sliding seat 63. The sliding seat 63 moves backward, causing its supporting effect on the contact block 8 to fail, and the suspension rod 7 falls. The guide blocks on both sides of the contact block 8 that are clamped on the inner side of the support rod 2 ensure that the suspension rod 7 falls vertically until its bottom casting is aligned with the The flip plate 5 collides, thereby loosening and shaking off the molding sand on the surface of the casting. At this time, the control cylinder 61 contracts, and the sliding seat 63 is reset under the action of the spring 65. When the cylinder 61 contracts to the lowest end, the inclined surface at the bottom end of the sliding seat 63 contacts the wedge-shaped surface at the top end of the contact block 8, so that the sliding seat 63 moves backward again, and resets after moving to the bottom of the contact block 8, and supports the contact block 8 again. After the cylinder 61 is driven to drive the suspension rod 7 to rise again, the motor 3 drives the connecting shaft 4 to rotate, so that the molding sand shaken off the surface of the flip plate 5 is dumped into the collecting box 1, providing a clean and hard surface for the molding sand to be shaken off, which is convenient for the falling and shaking off work again, thereby realizing the shaking off of the molding sand on the casting surface and the collection of the shaken-off molding sand.
