Description

Technical Field

[0001] The utility model belongs to the technical field related to workpiece casting, in particular to a casting ejection mechanism. Background Art

[0002] Workpiece casting is a manufacturing method that fills liquid metal into a pre-made mold, cools and solidifies it to obtain a casting blank with the desired shape, size and performance. This method is widely used in the blank manufacturing of mechanical workpieces because it can produce parts with complex shapes, especially blanks with complex inner cavities. After casting, it needs to be pushed out to remove the sand on the surface of the casting, and then pushed out to the appropriate position through the push-out structure. However, it still has the following disadvantages in actual use:

[0003] When the casting ejection mechanism is working, it directly pushes the casting. When the pushed casting moves to the appropriate position, the pushing speed is fast, which will cause the castings to collide with each other. When colliding, the momentum is large, which is easy to cause safety hazards;

[0004] When the casting ejection mechanism is working, since there is a large amount of casting sand on the surface of the casting, it needs to be transported to the external mounting structure and then the sand is removed by shot blasting. The operation steps are cumbersome and the work efficiency is low. Utility Model Content

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a casting ejection mechanism, comprising a conveying box, a pushing component 1, a pushing component 2 and a fixed plate, wherein the conveying box is arranged to be through-connected from top to bottom, a plurality of parallel supporting cross bars are fixed in the upper part of the conveying box, the length direction of the supporting cross bars is parallel to the width direction of the top of the conveying box, a fixing frame is fixed in the upper part of one end of the conveying box, a pushing component 1 and a pushing component 2 are movably connected in the upper part of the conveying box, the pushing component 1 and the pushing component 2 both comprise a fixing strip, a connecting strip, a supporting strip and a flexible baffle, the fixing strip included in the pushing component 1 is fixed with four equidistant supporting strips at the bottom, the pushing component 2 comprises Four equidistant connecting bars are fixed on the top of the fixing bar, and a supporting bar is fixed on the top of the connecting bar. Flexible baffles are evenly and equidistantly fixed on both sides of the supporting bar, and the top surface of the flexible baffle is arranged in a right-angled trapezoid. The four equidistant connecting bars included in the pushing component 1 and the pushing component 2 are staggered with each other. The lower part of both sides of the conveying box body is symmetrically fixed with a fixing plate with the center line in the vertical direction as the symmetry axis. When working, the pushing component 1 and the pushing component 2 are supported therein by the conveying box body. When the pushing component 1 works, it cooperates with the pushing component 2 to drive the casting output during pushing. When the fixed plate works, the vibration motor is fixed thereon.

[0008] Furthermore, an opening one is provided at the upper portion of one end of the conveying box body, an opening two is provided at the upper portion of one side of the conveying box body, a fixed frame is fixed at the end of the conveying box body away from the opening one, and a focusing bucket is fixed at the bottom of the conveying box body. When the conveying box body is working, the casting is output through the opening one, and the sand therein is concentrated through the focusing bucket.

[0009] Furthermore, both the pushing component 1 and the pushing component 2 also include fixed blocks. The fixing blocks are fixed at the two top edges of the fixing bar included in the pushing component 1, and the fixing blocks are fixed at the two bottom edges of the fixing bar included in the pushing component 2. When the pushing component 1 and the pushing component 2 are working, the hydraulic rod is connected through the fixed blocks.

[0010] Furthermore, the pushing component 1 and the pushing component 2 both include a hydraulic cylinder and a hydraulic rod. A hydraulic cylinder is provided on one side of each fixed block close to the fixed frame. The hydraulic cylinder is fixed to the side of the fixed frame. A hydraulic rod is movably connected inside the hydraulic cylinder. The hydraulic rod is inserted into the end of the conveying box. The end of the hydraulic rod away from the hydraulic cylinder is fixed to the fixed block. The hydraulic cylinder drives the hydraulic rod to move, which drives the fixed block to move. When the fixed bar moves, the support bar moves.

[0011] Furthermore, a vibration motor is fixed on the top of each of the fixing plates, and the vibration motor is fixed on both sides of the conveying box. When the fixing plates are working, the conveying box is driven to vibrate by the vibration motor.

[0012] Furthermore, a telescopic rod is fixed at the center of the bottom of the fixed plate, and compression springs are fixed to the bottom of the fixed plate outside the telescopic rod. The bottom ends of the telescopic rod and the compression spring are jointly fixed to a support plate. When the fixed plate is working, the telescopic rod and the compression spring cooperate to reduce vibration transmitted to the support plate, and the fixed plate is supported in a suitable position by the support plate.

At this time, the casting is pushed to a moving position by the moving support bar, and the hydraulic cylinder is started again, and the hydraulic cylinder drives the hydraulic rod to return to its position, and the pushing component two is started again, and the above work is repeated until the casting moves to the opening one and is output, so that during work, each workpiece is directly pushed by translation during conveying, and no collision will occur during conveying, and the safety hazard is smaller.

[0015] The utility model solves the problem of low working efficiency of sand removal by a casting pushing mechanism by arranging a conveying box, a pushing component one, a pushing component two and a fixed plate. When the casting enters the connecting strip in the conveying box, the vibration motor is started, and the vibration motor drives the fixed plate and the conveying box to vibrate, so that the casting in the conveying box vibrates, and the sand on the casting is shaken off and falls onto the supporting strip, and then is scattered into the conveying box through the supporting strip, and is concentrated by the concentrating bucket and falls onto the external conveyor belt. When the vibration motor is working, the telescopic rod and the compression spring cooperate to reduce the vibration transmitted to the supporting plate during operation, and the sand on the casting is directly removed by shaking because the supporting plate is supported on the external supporting structure, so that the working efficiency of the casting pushing mechanism to remove sand is higher.

During operation, the workpiece supported on the support bar 203 is pushed and moved by the fixed bar 201 when being pushed. When one fixed bar 201 is pushed, the other fixed bar 201 does not move.
