Description
Technical field
The utility model relates to vacuum valve field, the vacuum valve particularly a kind of vacuum die-casting mould used.
Background technology
The manufacture of conventional clutch adopts die-casting technique, but in press casting procedure, mold cavity can produce certain counter-pressure, causes filling condition bad, causes interiors of products to occur pore and sand holes.In order to improve this defect, the special evacuated die-casting process technology that adopts is produced.
But evacuated die-casting process technology itself also exists shortcoming, vacuum valve is one of indispensable element of evacuated die-casting process technology, but in vacuum, the alloy molten solution that there will be melting enters vacuum valve and the situation causing vacuum valve to damage.Vacuum valve price is higher, and fallible component is many, and upkeep cost is high, and the investment after vacuum valve damages is comparatively large, and needs configuration professional to manage, and gives training it, needs long-term technical support.
A kind of can reduce manpower and materials drop into and the vacuum valve preventing molten alloy liquation from entering becomes the key of dealing with problems.
Summary of the invention
The purpose of this utility model is to provide a kind of vacuum valve, can reduce the expense of vacuum valve, easy to use, practical, effectively prevents the alloy molten solution of melting from entering vacuum valve inside simultaneously, even if the alloy molten solution of melting enters valve body be also easy to cleaning.
For achieving the above object, the utility model adopts following technical scheme:
A kind of vacuum valve comprises: a main body and a cover plate, be provided with the washboard structure that can mutually be engaged in the bottom of main body and cover plate; Be provided with groove structure at body top, when after main body and cover plate occlusion, form a die cavity; Main body is provided with the vacuum-pumping pipeline that to communicate with die cavity; Main body and cover plate are respectively equipped with cooling water pipeline; Water blocking is respectively equipped with at cooling water pipeline end.
Preferably, cooling water pipeline is that two longitudinal passages and two lateral duct are interconnected and form on the body.
Preferably, on described cover plate, cooling water pipeline is that two longitudinal passages and three lateral duct are interconnected and form.
Preferably, cooling water intake and cooling water outlet is respectively equipped with on the top of described main body and cover plate.
Preferably, portion is provided with and vacuumizes interface on the body.
Preferably, when described main body is engaged with cover plate, between washboard structure, there is certain interval.
Preferably, described gap reduces from the bottom to top gradually.
Preferably, a boss is also provided with in described body recess.
The beneficial effects of the utility model are: because vacuum valve bottom have employed the washboard structure of occlusion mutually, the interstructural gap of washboard reduces from the bottom to top gradually, can effectively prevent the alloy molten solution of melting from entering the inside of vacuum valve, thus make vacuum valve not impaired, avoid vacuum valve maintenance and change part; Easy and simple to handle, substantially reduce the time of staff training, reduce production cost, improve productivity ratio.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, vacuum valve 3 is made up of a main body 1 and a cover plate 2, and cover plate 2 is on the body 1 sheathed.The bottom of described main body 1 is provided with the first washboard structure 108, and the bottom of described cover plate 2 is provided with the second washboard structure 204.Described first washboard structure 108 and the second washboard structure 204 can be engaged mutually.There is a groove in portion on the body 1, after main body 1 and cover plate 2 are engaged, can form a die cavity 107; Be provided with the vacuum-pumping pipeline 102 that to communicate with die cavity 107 on the body 1.Also be provided with cooling water pipeline 103 on the body 1, described cooling water pipeline 103 is interconnected by two longitudinal passages and two lateral duct and forms.Cover plate 2 is provided with cooling water pipeline 202, and described cooling water pipeline 202 is interconnected by two longitudinal passages and three lateral duct and forms.Water blocking 104 and water blocking 203 is also provided with at the end of described cooling water pipeline 103 and cooling water pipeline 202.
Be provided with cooling water intake 101, cooling water outlet 106 on described main body 1 top and vacuumize interface 105, being also provided with a boss 109 at the groove part of described main body 1.Cooling water intake 201, cooling water outlet 205 is provided with on described cover plate 2 top.
As shown in Figure 5 in use, first the end of the main body 1 of described vacuum valve 3 and the cooling water pipeline 103 of cover plate 2 and cooling water pipeline 202 is installed water blocking 104 and water blocking 203.The main body 1 of vacuum valve 3 and cover plate 2 are embedded respectively in the groove of vacuum die-casting mould 6, the main body 1 of vacuum valve 3 is connected with die cavity 5 respectively with bottom cover plate 2.The sound mould of described vacuum die-casting mould 6 is accurately fitted by mould lead 4, and simultaneously the main body 1 of vacuum valve 3 and cover plate 2 fit tightly under the effect of clamp force.
Then, described cooling water intake 101 is connected with external water inlet pipe respectively with cooling water intake 201, cooling water outlet 106 and cooling water outlet 205 respectively with pick out water pipe and be connected.Cooling water is flowed in the cooling water pipeline 103 and cooling water pipeline 202 of described vacuum valve 3, plays the object into vacuum valve 3 dispels the heat.Again the described interface 105 that vacuumizes is connected with vavuum pump by external pipeline.
When proceeding to vacuumizing phase, open vavuum pump, vacuum valve 3 starts to vacuumize described die cavity 5.Excessive gas in die cavity 5 is discharged, thus reduces the reaction force of molten alloy liquation to described vacuum die-casting mould 6, thus prevent die-cast product inside from occurring pore and sand holes.Simultaneously; first washboard structure 108 of described vacuum valve 3 bottom and the second washboard structure 204 are engaged mutually; gap between the first washboard structure 108 and the second washboard structure 204 can supplied gas be passed through; but because the first washboard structure 108 and the second washboard structure 204 are engaged mutually; the gap formed reduces from the bottom to top gradually; upper gap is less; the surface tension of molten alloy liquid is excessive; cannot pass through; therefore, it is possible to effectively stop the alloy molten solution of melting to enter die cavity 107 inside of vacuum valve 3, thus serve the not impaired object of protection vacuum valve 3.
Although embodiment of the present utility model is open as above, but it is not restricted to listed in description and embodiment utilization, it can be applied to various applicable field of the present utility model completely, for those skilled in the art, can easily realize other amendment, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend described.
