Abstract
The utility model relates to a quick gas charging valve for a cold-box core blower, which adopts the structure that an air cylinder is connected to one end of a three-way straight-through tube in a sealed manner, an end cover is connected to the other end of the three-way straight-through tube in a sealed manner, and a core hole is formed on an end cover, and a bearing cover capable of covering the core hole on the end cover in a sealed manner is connected to the front end part of a piston rod in the air cylinder. In the utility model, actions of the piston of the air cylinder is used in the three-way straight-through tube with a large aperture to carry out quick gas charging and switching, so that a mechanical valve with the large aperture, which is pushed by the air cylinder, is formed. Therefore, under the quick action of the air cylinder, the gas charging speed is accelerated, and the gas charging quantity every time can be increased by at least more than 50 percent. The quick gas charging valve for the cold-box core blower, provided by the utility model, is beneficial to the sand core formation, the sand core forming time is shortened, the quality and the yield of the sand core are improved, and the production efficiency is further improved.
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.
