Abstract
The utility model discloses a vacuum valve which comprises a moving die and a fixed die. The moving die and the fixed die are closed to form a vacuum valve cavity, a vacuum pump port is arranged at the top of the fixed die, the moving die comprises a valve casing and a connection block, a piston, a vacuum pipe, a plug-in key, a locking plate and a pin shaft are connected with the connection block, and an aluminum water sprue is arranged at the bottom of the moving die. The vacuum valve with the moving die and the fixed die is installed in a die-casting die to achieve vacuum casting. During vacuum pumping of the vacuum valve, the valve can automatically close a vacuum outlet when aluminum water reaches the vacuum valve and fills the vacuum valve cavity, so that vacuum pumping pipelines and vacuum devices can be effectively protected; and the vacuum valve is simple in structure, low in cost and capable of achieving vacuum casting.
Description
Technical field
The utility model belongs to valve technology field, relates to a kind of vacuum valve specifically.
Background technology
In the die casting manufacture process of prior art, in the goods that die casting goes out, all there is pore in various degree usually, cause the density of die cast product not high, defectives such as the stressed intensity difference behind the product molding.A lot of users are that direct exhaust outlet at mould vacuumizes in the prior art, and this way is damaged vaccum-pumping equipment through regular meeting, has strengthened production cost.At present domestic also do not have a kind of Related product that can address the above problem, so how can provide a kind of vacuum valve simple in structure, with low cost, that can realize vacuum pressing and casting to become the urgent demand of people.
Summary of the invention
The utility model is in order to overcome the deficiency that prior art exists, and a kind of simple in structure, with low cost, the vacuum valve that can realize vacuum pressing and casting is provided.
The utility model is realized through following technical scheme: a kind of vacuum valve; It comprises dynamic model and cover half; Constitute a vacuum valve die cavity after dynamic model and the cover half closure, be provided with the vavuum pump interface at the top of cover half, dynamic model comprises valve casing and contiguous block; On contiguous block, be connected with piston, vacuum tube, grafting key, locking plate and bearing pin respectively, be provided with aluminium water inlet in the bottom of dynamic model.
Be outside equipped with piston bushing at said piston.
Be outside equipped with the vacuum tube lining at said vacuum tube.
The beneficial effect of the utility model is: the vacuum valve of the utility model is installed in the die casting, and each one of dynamic model, cover half, thus realize vacuum pressing and casting.The vacuum valve of the utility model is in vacuum, and aluminium water has been filled the vacuum valve die cavity after arriving vacuum valve, and valve can cut out vacuum outlet automatically, can effectively protect vacuum-pumping pipeline and vacuum equipment.It is a kind of simple in structure, with low cost, the vacuum valve that can realize vacuum pressing and casting.
Description of drawings
Fig. 1 is the Facad structure sketch map of cover half in a kind of vacuum valve of the utility model;
Fig. 2 is the side cross-sectional view of dynamic model in a kind of vacuum valve of the utility model;
Among the figure: 1-vavuum pump interface; The 2-cover half; The 3-dynamic model; The 4-piston; The 5-vacuum tube; The 6-piston bushing; 7-vacuum tube lining; The 8-contiguous block; 9-grafting key; The 10-locking plate; The 11-bearing pin; 12-aluminium water inlet.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
As depicted in figs. 1 and 2; A kind of vacuum valve, it comprises dynamic model 3 and cover half 2, dynamic model 3 constitutes a vacuum valve die cavity with cover half 2 closed backs; Be provided with vavuum pump interface 1 at the top of cover half 2; Dynamic model 3 comprises valve casing and contiguous block 8, on contiguous block 8, is connected with piston 4, vacuum tube 5, grafting key 9, locking plate 10 and bearing pin 11 respectively, is provided with aluminium water inlet 12 in the bottom of dynamic model 3.Be outside equipped with piston bushing 6 at piston 4, be outside equipped with vacuum tube lining 7 at vacuum tube 5.
The course of work of the utility model vacuum valve is: the die casting machine matched moulds is accomplished, aluminium water casting complete, the injection of beginning low speed; Injection rod is crossed aluminium water and is watered the inlet back to signal; Vacuumize beginning in the mold cavity, injection rod advances at utmost speed, filling in the aluminium water propelled at high velocity mold cavity; Aluminium water has been filled the vacuum valve die cavity after arriving vacuum valve, and valve just cuts out vacuum outlet automatically.
Should be noted that at last; Above content is only in order to explain the technical scheme of the utility model; But not to the restriction of the utility model protection domain; The simple modification that those of ordinary skill in the art carries out the technical scheme of the utility model perhaps is equal to replacement, does not all break away from the essence and the scope of the utility model technical scheme.
Claims (3)
