Embodiment 1

[0044] see Figure 1-3, the present embodiment discloses a hot box core shooter, including a frame 100 as an installation base, a shakeout mechanism 10 is provided on the top of the frame 100, and the shakeout mechanism 10 is used to store sand materials, and remove the sand materials from The sand-out port 11 on it is transported to the sand-shooting cylinder 20, and the tail of the sand-shooting tube 20 can correspond to the sand-out port 11. After the sand material enters the sand-shooting tube 20, there can be high pressure in the sand-shooting tube 20. The gas is pushed and injected, and the frame 100 is also provided with a mold clamping mechanism 30 for clamping the hot core box mold, and a core pulling mechanism for fixing the formed sand core is provided under the mold clamping mechanism 30 40. The sand shooting port 21 of the sand shooting cylinder 20 can move back and forth up and down, so as to extend into or out of the mold cavity of the hot core box mold.

Embodiment 2

[0062] This embodiment is a deformation on the basis of Embodiment 1. The difference between this embodiment and Embodiment 1 is that, as another setting method of the sand shooting cylinder 20, the guide device also includes a The first guide rail 110 on the top, the first guide rail 110 passes through the outer sleeve 22, so that the sand shooting cylinder 20 can slide back and forth along the first guide rail 110 between the sand shakeout mechanism 10 and the mold clamping mechanism 30 between.

Embodiment 3

[0064] This embodiment is a modification based on Embodiments 1 and 2. In this embodiment, the guide device further includes a first guide rail 110 arranged on the frame 100, and the first guide rail passes through the The outer sleeve 22 enables the sand shooting cylinder 20 to slide back and forth along the first guide rail 110 between the shakeout mechanism 10 and the mold clamping mechanism 30, and also includes the sand shooting cylinder 20 moving along the first guide rail 110. A guide rail (110) slides back and forth between the guide part 22 between the sand shakeout mechanism 10 and the mold clamping mechanism 30, the setting of the guide part 22 combines the first guide rail 110 passing through the outer sleeve 22 so that the present embodiment The sand shooting cylinder 20 can move on the first guide rail 110 more stably, so that the phenomenon of lateral deviation is less likely to occur.

Abstract

The invention discloses a core shooting machine of a hot core box. The machine comprises a machine frame, a sand falling mechanism which is arranged at the top of the machine frame, a sand shooting cylinder of which the tail part is used for receiving sand materials falling from a sand falling opening formed in the lower end of the sand falling mechanism, a mold clamping mechanism which is used for clamping a mold of the hot core box, and a core pulling mechanism which is fixed below the mold of the hot core box and is used for ejecting a molded sand core out, wherein, the sand shooting opening of the sand shooting cylinder can move up and down and back and forth to extend out of a mold cavity of the mold of the hot core box, and a base is not required to be supported by a supporting structure, so that the machine does not need to be manufactured or designed by high-strength materials, and the heavy weight is avoided. The machine has the advantages of cost conservation and high production efficiency.

Description

technical field [0001] The invention relates to a hot core box core shooter, which belongs to the technical field of core shooters. Background technique [0002] In foundry production, the requirements for sand cores are very high. The traditional core making method is to make cores by mixing raw sand and synthetic grease at room temperature or by mixing glass water glue and raw sand and blowing carbon dioxide into the core to harden. Place cold iron by hand. With the improvement of the market's requirements for product quality and the continuous improvement of the production process, the coated sand hot box core making process has been widely used. The hot box core making means that the mold is equipped with electric heating tubes or other heating devices. When the sand material is blown into the mold cavity, it is heated by the electric heating tube and hardened and compacted into a core under the high pressure provided by the sand cylinder. The sand core must have suffi...
