Problems solved by technology
Generally speaking, the nozzle itself does not have a cooling function, and the mixture of resin and molding sand in the nozzle may solidify in the nozzle due to high temperature, causing it to be blocked, so that continuous production cannot be carried out. Dredging and cleaning will definitely waste working time and affect work efficiency

Embodiment Construction
[0015] The present invention will be further described below in conjunction with accompanying drawing and embodiment:
[0016] Such as Figure 1~3 The nozzle of an inorganic resin process temperature core box shown includes a nozzle body 1 installed on the shooting board, a nozzle head 2 installed at the lower part of the nozzle body 1, and the nozzle body 1 and the nozzle head 2 have a connection There is a sand-shooting channel 3 through which the sand-shooting channel 3 is located at the outlet of the nozzle head 2 with an aperture of 4 to 30 mm, and a nozzle sleeve 7 is set outside the nozzle head 2.
[0017] Wherein: the nozzle body 1 includes a first nozzle body 10 and a second nozzle body 11 arranged inside the first nozzle body 10 . In this embodiment, a cooling water channel 8 is formed between the inner wall surface of the first nozzle body 10 and the outer wall surface of the second nozzle body 11, and the inner wall surface of the second nozzle body 11 forms the n...

Abstract
The invention relates to a nozzle of an inorganic resin process temperature core box. The nozzle comprises a nozzle body and a nozzle head arranged at the lower part of the nozzle body; communicated sand shooting passages are formed in the nozzle body and the nozzle head; the nozzle body comprises a first nozzle body and a second nozzle body arranged in the first nozzle body; a cooling water passage is formed between the first nozzle body and the second nozzle body; the first nozzle body is provided with a water inlet and a water outlet; and the water inlet, the cooling water passage and the water outlet are connected and form an access. The cooling water passage arranged on the nozzle structure effectively cools the nozzle, so that the mixture of molding sand and inorganic resin in the nozzle is not cured due to over high temperature is ensured, blockage of the nozzle is avoided, and continuous batch production is realized.
Description
technical field [0001] The invention relates to an inorganic resin process warming core box, in particular to a nozzle used on the warming core box. Background technique [0002] At present, inorganic resins are widely used for core making due to their low environmental pollution. When making cores by inorganic resin technology, the main process steps are as follows: mix resin and molding sand, shoot sand from the nozzle of the sand shooting board, and then solidify the sand cores in the core box. The difficulty of this process is that the formed sand core is solidified by heating, which will increase the temperature of the sand shooting environment of the nozzle. Generally speaking, the nozzle itself does not have a cooling function, and the mixture of resin and molding sand in the nozzle may solidify in the nozzle due to high temperature, causing it to be blocked, so that continuous production cannot be carried out. Dredging and cleaning will definitely waste working tim...
