Description

Technical Field

[0001] The utility model relates to the technical field of casting devices, and particularly relates to a core-taking tool suitable for a coated sand blade core. Background Art

[0002] In the coated sand core-making process, the mixed coated sand is injected into the mold cavity by a core shooter and hardened and formed under the condition of 200°C to 300°C. The coated sand has high strength and low gas evolution, which can effectively reduce the risk of pores and pinholes in the casting; at the same time, the coated sand has good fluidity, can completely form the complex internal structure of the casting, and improve the dimensional accuracy and surface finish of the casting. However, without the aid of a special core-taking tool, manual core-taking is not only inefficient but also easy to damage the sand core, and there is a risk of scalding the operator during operation. Summary of the Invention

[0003] To solve the above technical problems, the utility model provides a core-taking tool suitable for a coated sand blade core.

[0004] The core-taking tool suitable for the coated sand blade core provided by the utility model includes a boss and a handle. The boss is a conforming boss, and the shape of the boss is designed conformingly according to the outer contour of the blade sand core.

[0005] Further, the number of the conforming bosses is preferably 3, which is suitable for core-taking of three blade sand cores. It not only has high core-taking efficiency but also can better avoid damage to the sand core during the core-taking process.

[0006] Further, the position of the conforming boss corresponds to the position of the blade in the mold cavity. When taking the core, the core shooter ejects the sand core, and the sand core falls on the conforming boss of the core-taking tool, and the core-taking tool is used to take away the sand core.

[0007] Further, the core-taking tool is made of aluminum alloy material, which is light and convenient for on-site operation.

[0008] Further, the handle is a length-adjustable handle, which is used to place the core-taking tool on the mold parting surface. The length of the handle can be adjusted according to needs, so as to effectively avoid the risk of scalding the operator during core-taking.

[0009] The beneficial effects of the utility model are as follows:

[0010] The core-taking of the utility model is fast, efficient, does not damage the sand core, can effectively avoid the risk of scalding the worker during operation, is simple and convenient to operate, easy to manufacture, reusable, and has low production cost, and is worthy of popularization and use. Brief Description of the Drawings

[0011] Figure 1 It is a schematic structural diagram of the utility model.

[0012] In the figure: 1 - conforming boss, 2 - handle

[0013] Figure 2 This is a schematic structural diagram of the blade core sand taken by the present utility model.

[0014] Figure 3 This is a schematic structural diagram of the core-taking state of the present utility model. Specific implementation manners

[0015] The following further elaborates on the present utility model in detail with reference to the accompanying drawings, but the present utility model is not limited thereto.

[0016] As Figure 1 shown, the present utility model includes a boss 1 and a handle 2. The boss 1 is three conforming bosses. The shape of the boss 1 is designed to conform to the outer contour of the blade core sand. The position of the conforming boss 1 corresponds to the position of the blade in the mold cavity. The handle 2 is a handle with adjustable length, which is used to place the core-taking tool on the mold parting surface, and the length of the handle can be adjusted as needed.

[0017] During core making, three blade core sands are formed in one mold by injecting coated sand into the core box; three conforming bosses are designed on the core-taking tool according to the outer contour shape of the blade core sand; as Figure 2 、 3 shown, after core shooting is completed, the mold is opened, and the operator holds the handle 2 and places the core-taking tool on the mold parting surface; the core shooter ejects the core sand, and the three blade core sands fall on the conforming boss 1, and the core sand is taken away with the help of the core-taking tool.
