Abstract
The invention relates to a large-sized sand shooting nozzle which comprises a nozzle body and a nozzle head serving as a quick-wear replacement part, wherein one end of the nozzle head is sleeved in an opening end of the nozzle body, the other end of the nozzle head is provided with a sand blocking straight section, a nozzle blocking piece rib is arranged in the sand blocking straight section, the nozzle blocking piece rib is fully distributed in the sand blocking straight section in a net structure, and a plurality of meshes formed between the nozzle blocking piece ribs are used as nozzle holes. The invention solves the problems of more nozzles, more impressions of the nozzles, sand falling of the oversized nozzles and poor quality of the sand core in the conventional large sand core, improves the mold filling capacity of the nozzles, improves the diameter range of the nozzles to phi 21-phi 150mm, prevents sand falling and improves the quality of the sand core.
Description
Technical Field
The invention relates to the technical field of core box sand core casting production, in particular to a large-sized sand shooting nozzle.
Background
The existing nozzle is influenced by sand drop factors, the maximum diameter is limited, the maximum diameter is not more than 21mm, and the sand drop phenomenon can occur when the maximum diameter exceeds 21mm, so that the production is influenced.
Aiming at the problems, the invention provides a large sand shooting nozzle, which solves the problems of more sand core shooting nozzles, more sand core shooting nozzle impressions, sand falling of an oversized shooting nozzle and poor sand core quality of the conventional large sand core, improves the mold filling capacity of the sand shooting nozzle, prevents sand falling and improves the sand core quality.
Disclosure of Invention
The invention aims to overcome the problems in the prior art and provides a large-sized sand shooting nozzle.
In order to achieve the technical purpose and achieve the technical effect, the invention is realized by the following technical scheme:
the utility model provides a large-scale shooting nozzle, includes the nozzle body and regard as the nozzle head that easily changes the piece, the one end of nozzle head cup joints in the open end of nozzle body, and the other end of nozzle head is equipped with the straight section of keeping off the sand, be equipped with shooting nozzle separation blade muscle in the straight section of keeping off the sand, inside shooting nozzle separation blade muscle was that network structure covered with the straight section of keeping off the sand, a plurality of meshes that form between the shooting nozzle separation blade muscle were as the nozzle hole.
Furthermore, the nozzle head, the sand blocking straight section and the nozzle blocking piece rib are of an integrated structure.
Furthermore, a nozzle sleeve is sleeved on the exposed side surface of the nozzle head and used for sealing during nozzle shooting.
Furthermore, a groove structure is formed in the side face of the nozzle head corresponding to the root of the nozzle sleeve, and a corresponding protruding structure is arranged at the root of the nozzle sleeve and is in matched hooking connection with the groove structure on the nozzle head to prevent the nozzle sleeve from falling.
Furthermore, the outer side of the nozzle head and the inner side of the opening of the nozzle body are screwed together through a thread structure, so that the nozzle is convenient to unscrew and replace.
The invention has the beneficial effects that:
the invention solves the problems of more nozzles, more impressions of the nozzles, sand falling of the oversized nozzles and poor quality of the sand core in the conventional large sand core, improves the mold filling capacity of the nozzles, improves the diameter range of the nozzles to phi 21-phi 150mm, prevents sand falling and improves the quality of the sand core.
Drawings
FIG. 1 is a schematic top view of the present invention;
FIG. 2 isbase:Sub>A sectional view taken along line A-A of FIG. 1;
fig. 3 is a perspective view of the nozzle head according to the present invention.
The reference numbers in the figures illustrate: 1. the nozzle comprises a nozzle body, 2, a nozzle head, 21, a sand blocking straight section, 22, a nozzle blocking piece rib, 23, a nozzle hole, 3 and a nozzle sleeve.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings in combination with embodiments.
As shown in fig. 1 to 3, a large-sized sand shooting nozzle comprises a nozzle body 1 and a nozzle head 2 as a quick-wear replacement part, wherein one end of the nozzle head 2 is sleeved in an opening end of the nozzle body 1, a sand blocking straight section 21 is arranged at the other end of the nozzle head 2, nozzle blocking plate ribs 22 are arranged in the sand blocking straight section 21, the nozzle blocking plate ribs 22 are distributed in the sand blocking straight section 21 in a net structure, the net structure can be a spider net structure or a cross net structure, a plurality of meshes formed between the nozzle blocking plate ribs 22 are used as nozzle holes 23, the phi 21mm with the largest inner diameter (the diameter of core sand passing through the inside of the nozzle hole 23) of a conventional nozzle can be enlarged to the range of phi 21 mm-phi 150mm, if the inner diameter is directly enlarged and the nozzle blocking plate ribs 22 are lacked, sand can directly leak from a large hole, the sand leaks continuously, and after the nozzle blocking plate ribs 22 are adopted, the large hole is controlled and separated, so that the sand has a safety angle, and the quality of the sand is reduced.
The nozzle head 2, the sand blocking straight section 21 and the nozzle blocking piece rib 22 are of an integral structure.
The side surface of the nozzle head 2 exposed is sleeved with a nozzle sleeve 3, and the nozzle sleeve 3 can be made of rubber and is used for sealing during nozzle injection.
As shown in fig. 2, a groove structure is formed at the side of the nozzle head 2 corresponding to the root of the nozzle sleeve 3, and a corresponding protrusion structure is arranged at the root of the nozzle sleeve 3 and is hooked with the groove structure on the nozzle head 2 in a matching manner, so as to prevent the nozzle sleeve 3 from falling.
The outer side of the nozzle head 2 and the inner side of the opening of the nozzle body 1 are screwed together through a thread structure, so that the nozzle head 2 is convenient to unscrew and replace.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
