Problems solved by technology

However, in the prior art, when zirconium sand is injected, phenomena such as sand leakage, shunting and decompression often occur due to the lax sealing of the injection head, which on the one hand makes the injection unreal; on the other hand causes waste

Embodiment

[0018] Please refer to Figure 1-Figure 3 , the present embodiment is a sand shooting quantitative structure 100 for automatic core shooting, which is mainly used in conjunction with sand molds. It includes a nozzle body 1 and a first cavity 2 formed by the cooperation of the nozzle body 1 and the sand mold.

[0019] The shot head body 1 includes a sand inlet 11 arranged on the upper surface, a first enclosure body 12 and a second enclosure body 13 which form the first cavity 2 and are oppositely arranged.

[0020] The first enclosure body 12 has the same structure as the second enclosure body 13, and includes a second cavity 121 which is hollow inside, a first sealing plate 122 which closes one side of the second cavity 121, and a second sealing plate 122 which closes the other side of the second cavity 121. The second sealing plate 123 on the surface. The second sealing plate 123 is provided with a main sand injection port 124 and a secondary sand injection port 125 communi...

Abstract

The invention discloses a quantitative sand shooting structure for automatic sand shooting. The structure is mainly used with a sand mold cooperatively, and comprises a shooting head body and a first cavity which is cooperatively defined by the shooting head body and the sand mold, wherein the shooting head body comprises a sand inlet, a first fence body and a second fence body; the sand inlet is formed in the upper surface of the shooting head body; two opposite surfaces of the first cavity are defined by the first and second fence bodies which are of the same structure; a second cavity communicating with the first cavity is formed inside the first fence body; and the sand inlet communicates with the second cavity. By adoption of the structure provided by the invention, a crack which is likely to cause sand overflow can be sealed, thereby avoiding sand flow from being split, decompressed and wasted; a correct sand shooting position and a dense sand shooting process can be guaranteed; the double-aggregate sand production efficiency is effectively improved; and the zircon sand consumption is reduced.

Description

【Technical field】 [0001] The invention belongs to the technical field of sand molding, and in particular relates to a sand shooting quantitative structure for automatic core shooting. 【Background technique】 [0002] The market demand for rail aluminothermic welding products has increased significantly, and the delivery time of sand molds and crucibles required by customers is getting shorter and shorter. There is a serious shortage of production capacity for sand mold products. The production efficiency of the company's original core shooting system is low. The zirconium sand molding process in the double aggregate sand mold requires manual work, adding sand and compacting. Manual operation has defects such as low efficiency, large amount of sand used, random amount of sand added, and poor production environment. It is very necessary to develop a new type of automatic core shooting machine system and upgrade it to automatic core shooting operation of zirconium sand. And a k...
