Description

Technical Field

[0001] This utility model belongs to the technical field of cylinder casting cleaning, and specifically relates to a sand-removing device for quickly cleaning the core sand inside the cylinder barrel of a cylinder casting. Background Technology

[0002] Currently, during the process of cleaning cylinder castings from the molding stage to the machining stage, there is a large amount of residual core sand inside the cylinder barrel, which completely blocks the cylinder barrel, affecting the next shot blasting operation. Furthermore, the large amount of core sand entering the shot blasting system exacerbates the wear on the equipment's wear-resistant parts, greatly affecting their service life.

[0003] Cleaning core sand generally involves using a sand-removing machine to vibrate the sand and manual cleaning. However, since some cylinder blocks require hot-pressing, the core sand temperature is high, and thermal expansion causes the sand-removing machine to be unable to vibrate and remove the sand. Manual sand removal is extremely difficult. Therefore, there is an urgent need for a sand-removing device that can quickly clean the core sand inside the cylinder barrel of cylinder block castings. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a sand-clearing device for quickly cleaning the core sand inside the cylinder barrel of a cylinder casting.

[0005] The technical solution adopted by this utility model is a sand-removing device for quickly cleaning the core sand inside the cylinder barrel of a cylinder casting. It includes a rectangular base, on which multiple sand-removing cones are arranged corresponding to the cylinder barrel position of the cylinder casting. Each sand-removing cone consists of at least three inserts arranged circumferentially. The inner sides of the inserts intersect and coincide with the central axis of the cylinder barrel, and the outer sides of the inserts are parallel to the central axis of the cylinder barrel. The upper side of the inserts gradually decreases in height from the center to the outside to form a cone tip. The overall height of the sand-removing cone is higher than the height of the cylinder barrel, and the maximum circumferential distance is less than the diameter of the cylinder barrel.

[0006] Furthermore, the sand-piercing cone includes four inserts, which are perpendicular to each other to form a cross-shaped sand-piercing cone.

[0007] Furthermore, the base includes a rectangular base plate and a panel, with the two sides of the base plate and panel connected by side plates, and the bottom end of the sand-piercing cone is fixed to the panel.

[0008] Furthermore, both the base and the sand-piercing cone are made of steel plates and are connected by welding.

[0009] This utility model has the following beneficial effects:

[0010] This utility model has a simple structure, stable performance, low cost, and easy operation. It can quickly clean the core sand inside the cylinder of the cylinder casting, reduce labor intensity and subsequent manual cleaning intensity, and effectively improve work efficiency and production efficiency.

[0016] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a sand-clearing device for quickly cleaning the core sand inside the cylinder barrel of a cylinder casting.

[0017] like Figures 1-4 As shown, a sand-removing device for quickly cleaning the core sand inside the cylinder barrel of a cylinder casting includes a rectangular base 3. Multiple sand-removing cones 2 are arranged on the base 3 corresponding to the cylinder barrel position of the cylinder casting 1. Each sand-removing cone 2 consists of at least three inserts arranged circumferentially. The inner sides of the inserts intersect and coincide with the central axis of the cylinder barrel. The outer sides of the inserts are parallel to the central axis of the cylinder barrel. The upper side of the inserts gradually decreases in height from the center to the outside to form a cone tip. The overall height of the sand-removing cone 2 is higher than the height of the cylinder barrel, and the maximum circumferential distance is less than the diameter of the cylinder barrel.

[0018] In this embodiment, both the base 3 and the sand-piercing cone 2 are made of steel plate. The base 3 includes a rectangular base plate and a panel, and the two sides of the base plate and the panel are connected by side plates. The sand-piercing cone 2 includes four inserts, which are perpendicular to each other to form a cross-shaped sand-piercing cone 2. There are six sets of sand-piercing cones 2, and the spacing of the six sets of sand-piercing cones 2 matches the position of the cylinder barrel of the cylinder casting 1. Their bottom ends are welded and fixed to the panel.

[0019] When in use, place the sand-clearing device at the unloading point of the robotic arm. After the robotic arm grabs the cylinder casting 1, inserts the cylinder into the tip of the sand-clearing cone 2 and presses it down. After the sand clearing is completed, transfer it to the manual part removal point, and then clean up the remaining sand manually.
