Problems solved by technology

In the prior art, when the hot core box is used to make cores, if sand rods are produced, the sand core needs to be repaired, which wastes raw materials and greatly reduces production efficiency; if ordinary plug-in nozzles are used, sand rods and repair sand The trouble of the core saves the raw sand and improves the qualified rate of the sand core; however, due to the high temperature of the working environment, the coated sand in the nozzle is easy to solidify and block the sand-shooting channel in the nozzle, so it is necessary to frequently Cleaning the sand shooting channel is time-consuming and material-consuming

Embodiment Construction

[0011] The specific structure and working principle of the present invention will be further described below in conjunction with the accompanying drawings.

[0012] See attached figure 1 - As shown in -2, a plug-in hot core box water-cooled nozzle structure is installed on the sand shooting board 1, the structure includes a nozzle 2 with a sand shooting channel 3, and the nozzle 2 includes a nozzle body 4 and a nozzle body 4. The nozzle head 5 installed on the lower end of the nozzle body 4, the sand-shooting passage 3 includes a body passage 6 in the nozzle body 4 and a head passage 7 in the nozzle head 5. When sand is shot, the nozzle head 2 Insert into the upper core box and inject the core sand into the cavity. The temperature in the cavity is generally 200-400°C. The high temperature loose sand is used to solidify to form a sand core. Since there is loose sand in the nozzle 2, the environment of the core box The high temperature will also solidify part of the dispersed s...

Abstract

The invention discloses a water cooling nozzle structure of an inserted hot core box, which comprises a nozzle provided with a sand shooting passage. The nozzle comprises a nozzle body and a nozzle head arranged at the lower end of the nozzle body, and the sand shooting passage comprises a body passage positioned in the nozzle body and a head passage in the nozzle head. The structure is characterized in that a cooling water passage encircling the sand shooting passage is formed between the inner wall and the outer wall of the nozzle, and the cooling water passage extends along the axial direction of the sand shooting passage. By using a water cooling nozzle and loose sand in the water cooling nozzle, the loose sand can keep a flowing state by reduction of temperature, and does not block the nozzle, so the structure saves time for frequently cleaning the nozzle, can achieve continuous production, and improves production efficiency.

Description

technical field [0001] The invention relates to a plug-in hot core box water-cooled nozzle structure. Background technique [0002] The hot core box core making technology is to inject coated sand into the high temperature core box cavity, and use the heat energy of the core box body to solidify the loose sand to form a sand core for casting casting. In the prior art, when the hot core box is used to make cores, if sand rods are produced, the sand core needs to be repaired, which wastes raw materials and greatly reduces production efficiency; if ordinary plug-in nozzles are used, sand rods and repair sand The trouble of the core saves the raw sand and improves the qualified rate of the sand core; however, due to the high temperature of the working environment, the coated sand in the nozzle is easy to solidify and block the sand-shooting channel in the nozzle, so it is necessary to frequently Cleaning the sand shooting channel is time-consuming and material-consuming. Cont...
