Abstract
The utility model relates to a quick inflation valve of a cold box core shooter, which is structurally characterized in that a cylinder is sealed at one end of a straight-through pipe of a tee joint, an end cover is sealed at the other end of the straight-through pipe, and a core hole is arranged on the end cover; the front end part of a piston rod in the cylinder is connected with a supporting cover which can seal the core hole on the end cover. The utility model discloses utilize the piston action of cylinder to carry out quick aerate and turn-off in the tee bend of large aperture, formed the large aperture mechanical valve that a cylinder promoted, like this, under the quick action of cylinder, just can improve the gas velocity to the air charge at every turn also can improve more than 50% at least. The utility model discloses be favorable to the psammitolite shaping, shorten psammitolite shaping time, improve psammitolite quality and yield, also improved production efficiency.
Description
Technical field
The utility model relates to a kind of parts of moulding machine, specifically a kind of cold-box core blower fast aeration valve.
Background technology
Existing cold-box core blower penetrate sand with air jet system in, generally all be that the combined mechanism of a plurality of valvelets of employing is controlled jet amount.The aeration speed of this controlling organization is not high, and each aeration quantity is less, thereby has influenced the shaping speed of penetrating sand effect and core and the molding effect of core shooter.
The utility model content
The purpose of the utility model just provides a kind of cold-box core blower fast aeration valve, to solve the low and aeration quantity problem of smaller of aeration speed that existing jet controlling organization exists.
The utility model is achieved in that a kind of cold-box core blower fast aeration valve, is sealed with cylinder at an end of the straight pipe of threeway, is sealed with end cap at the other end, on said end cap, has the core hole; But the leading section of the piston rod in said cylinder is connected to the holder lid in the said core hole on the said end cap of capping.
Said cylinder comprises cylinder body, cylinder head, piston and piston rod; Said cylinder body sealing-in is in the port of said threeway, and the said piston rod cross-under of joining with said piston in the cylinder body is in the straight pipe of said threeway.
The utility model utilizes the piston action of cylinder to carry out fast aeration and shutoff in wide-aperture threeway; Formed the large aperture mechanical valve that a kind of cylinder promotes, like this, under the quick acting of cylinder; Just can improve aeration speed, and each aeration quantity can improve more than 50% also at least.The utility model helps the core moulding, shortens the core molding time, improves core quality and yield rate, has also improved production efficiency.
Below in conjunction with accompanying drawing the utility model is done further detailed description.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The title of each numbered block and label are respectively among the figure: 1, threeway, 2, cylinder head, 3, screw, 4, cylinder, 5, piston, 6, piston rod, 7, nut, 8, Tuo Gai, 9, sealing ring, 10, the core hole, 11, end cap.
The specific embodiment
As shown in Figure 1, the utility model is at the left end sealing-in one cover cylinder of the straight pipe of threeway 1, and end cap 11 of right-hand member sealing-in has core hole 10 on end cap 11; The by-pass port of threeway 1 is used to connect source of the gas.
The cylinder of sealing-in on threeway 1 left port adopts conventional structure, comprises parts such as cylinder body 4, cylinder head 2, piston 5 and piston rod 6.Cylinder body 4 sealing-ins of cylinder are in the port of threeway 1, and cylinder head 2 is fixed on through screw 3 on the port of cylinder body 4, and piston 5 is contained in the cylinder body 4, and the piston rod 6 that joins with piston 5 passes cylinder body 4, and cross-under is in the straight pipe of threeway 1.Be fixedly connected with holder at the leading section of piston rod 6 through nut 7 securing members such as grade and cover 8, hold in the palm and cover the 8 core holes 10 that can cover on the end cap 11.Be to improve air-tightness, cover 8 stitching surface in holder and be provided with sealing ring 9.
