Description
Technical field
The present invention relates to overlay film sand molding process equipment technology fields, and in particular to a kind of sand shooting mouth.
Background technique
Sand shooting mouth is one of precoated sand mo(u)lding equipment technological equipment, as a part for penetrating sand system.Precoated sand
When moulding, under the action of compressed air, precoated sand is sprayed from sand shooting mouth, and the type chamber of mold is entered after sand ejection board, complete
At overlay film sand molding.
In the prior art, it is single-pass configuration for the sand shooting mouth of overlay film sand molding, is primarily present following problems:
It is fallen on mold first is that having part molding sand after penetrating sand, needs manually to be cleared up with scraper plate, one side
Face manual cleaning the degree of automation is low, and the efficiency and quality of cleaning are also poor, artificial clear on the other hand since mold temperature is higher
There are security risks for reason.
Second is that the scalable spray head of existing its front end of sand shooting mouth is spring compression structure, it is the active force by spring
That since the pressing force of spring is relatively small, fatigue can be also generated after long-time service so that spray head is adjacent to sand ejection board, so as to
Reliability decrease under the conditions of high pressure penetrates sand can be will lead to, there are gas leakage or sand leakage the place of being adjacent to of spray head and sand ejection board can
Can, and accelerate the abrasion of sand shooting mouth forward end seal bumper ring in turn.
Summary of the invention
To solve the above-mentioned problems, the present invention proposes a kind of sand shooting mouth, improves the degree of automation of overlay film sand molding, simultaneously
Improve the reliability for penetrating sand operation.Specific technical solution is as follows:
A kind of sand shooting mouth, including with sand filling passageway, shake out channel and return sand channel threeway valve body, be arranged described
