Abstract
The invention provides a multi-functional press-down gas bag of a core shooting machine, which comprises a bracket, a compact cylinder, an airway and a gas bag, wherein, the airway is arranged in thegas bag and the two ends of the airway go out of the gas bag; the upper end of the airway is provided with an upper end cover which is connected with a piston rod of the compact cylinder; a side wallof the upper part of the airway is provided with an air inlet which is communicated with the interior of the gas bag, and the upper end cover of the airway is provided with an air control port; a sandshooting valve is arranged in the airway and below the upper end cover, a sand filter screen is positioned in a lower port of the airway and an exhaust valve is arranged on the side wall of the airway at the upper part of the sand filter screen. The aeration mode can cause a shooting head of the core shooting machine to obtain the maximum sand shooting force with even pressure, which ensures thestructural strength of sand cores, realizes the substantial upper exhaust as well as causes the sand filter screen to be automatically blown back and cleaned and fully ensures the smoothness of each exhaust; the residual air in a shooting cavity of the core shooting machine is exhausted completely within shorter time; and no phenomenon of sand leakage in a shooting hole exists when the shooting head of the core shooting machine is lifted, therefore, the exhaust time is fully shortened and the production efficiency is improved.
Description
Technical field
The present invention relates to core shooter supporting press down gas bag, belong to the core shooter technical field in the foundry machinery.
Background technology
In the whole technical process of Foundry Production, the production of core is an important link, and core not only will have enough intensity, size, profile clearly accurately, and good collapsibility will be arranged.Whole core manufacturing craft process equipment needed thereby have puddle mixer, core shooter and with the supporting aerogenerator of triethylamine of core shooter.At present the problem that the sand gas extraction system exists of penetrating of core shooter is: penetrating the sand high pressure draught is to enter from penetrating the side, chamber by the rubber film valve, and penetrating the chamber, built-in to penetrate sand bucket fragile; More serious problem is that the Sand jet valve rubber film usually breaks suddenly, causes unexpected stopping production.Rubber film and to penetrate the replacing of sand bucket all pretty troublesome reduces production efficiency, and the increase expense influences ordinary production.And it is bigger to penetrate the sand bucket slit, and air bleeding valve filter sand Netease amasss the sand plug plug, and exhaust is not smooth, and evacuation time increases, and production efficiency reduces.
Summary of the invention
The present invention is directed to the problem that the sand gas extraction system exists of penetrating of existing core shooter, a kind of equal injection sand, unobstructed multi-functional gas bag that presses down of core shooter of exhaust realized is provided.
The multi-functional gas bag that presses down of core shooter of the present invention adopts following technical solution:
The multi-functional gas bag that presses down of this core shooter comprises support, hold-down cylinder, air flue and gas bag, air flue is installed in the gas bag, its two ends pass gas bag, the upper end is provided with upper end cover, and the piston rod of hold-down cylinder is connected with the upper end cover of air flue, and the air flue upper portion side wall is provided with the air inlet with the gas bag internal communication, the upper end cover of air flue is provided with the gas control mouth, the below of the inherent upper end cover of air flue is provided with Sand jet valve, is provided with the filter sand net in the air flue end opening, is provided with air bleeding valve on the air flue sidewall of the online portion of filter sand.
During work, start hold-down cylinder, it is descending to drive air flue, the end opening of air flue aim at core shooter penetrate a sealing of interruption-forming on the chamber penetrate the sand environment.Sand jet valve is opened, and high pressure draught in mode the most efficiently, flings the center, chamber of penetrating through the filter sand net along the axis.After Sand jet valve was closed, air bleeding valve was opened, and the residual air of penetrating in the chamber is discharged behind the filter sand net filtration; The filter sand net obtains returning the blowing-out reason when penetrating sand once more, for next step air blowing creates good conditions.
Inflation mode of the present invention can make the head of penetrating of core shooter obtain maximum equal injection sand power, has guaranteed the structural strength of core.Realized the substantial exhaust of going up, can make the filter sand net obtain returning the blowing-out reason automatically, guaranteed the unobstructed of each exhaust fully, make core shooter penetrate residual air emptying in the short period of time in the chamber, core shooter is penetrated and is not occurred perforation leakage sand phenomenon when head lifts, evacuation time fully shortens, and has improved production efficiency.

The specific embodiment
As depicted in figs. 1 and 2, the multi-functional gas bag that presses down of core shooter of the present invention mainly comprises support 9, hold-down cylinder 1, air flue 5 and gas bag 8, air flue 5 welds together with gas bag 8, gas bag 8 is passed at its two ends, the upper end is provided with upper end cover, hold-down cylinder 1 is installed in the upper end of support 9, and its piston rod is connected with air flue 5 upper end covers by ball-joint 2, and the upper portion side wall of air flue 5 is provided with the air inlet 11 with gas bag 8 internal communication.This air inlet 11 is positioned at more than the close mouth of Sand jet valve 3.Gas bag 8 is provided with gases at high pressure import and pressure regulator valve.The upper end of air flue 5 is provided with gas control mouth 10, and the internal upper part of air flue 5 is provided with Sand jet valve 3, and interior bottom is provided with filter sand net 6, is provided with air bleeding valve 7 on the air flue sidewall of the online portion of filter sand.Travel switch 4 is installed on the support 9, with the stroke of control piston bar, also is simultaneously the stroke of control air flue 5.
Running of the present invention is:
When not working, gas control mouth 10 air inlets of air flue 5 upper ends, the piston of Sand jet valve 3 moves down, and closes Sand jet valve 3, makes air flue 5 inner and gas bag 8 disconnections, and the gases at high pressure in the gas bag 8 can not enter air flue 5 inside.
During work, start hold-down cylinder 1, it is descending to drive air flue 5, the end opening of air flue 5 aim at core shooter to penetrate the chamber suitable for reading and compress, what form a sealing penetrates the sand environment.Gas control mouth 10 exhausts of air flue 5 upper ends, the piston that the gases at high pressure in the gas bag 8 are opened Sand jet valve 3 through air inlet 11 enters air flue 5 inside.The high pressure draught of air flue 5 inside in mode the most efficiently, flings the center, chamber of penetrating through filter sand net 6 along the axis.This inflation mode can make the head of penetrating of core shooter obtain maximum equal injection sand power, and the structural strength that guarantees the ring-type core is had important effect.
After Sand jet valve 3 was closed, air bleeding valve 7 was opened, and the residual air that core shooter is penetrated in the chamber is discharged after filter sand net 6 filters.Filter sand net 6 obtains returning the blowing-out reason when penetrating sand once more, has guaranteed the unobstructed of each exhaust fully, makes the residual air emptying in the short period of time of penetrating in the chamber, and perforation leakage sand phenomenon does not appear in penetrating of core shooter when head lifts, for next step air blowing creates good conditions.Realized the substantial exhaust of going up.
