Abstract
The utility model discloses a structure of die casting metal and plastic spray nozzle with a sealed vacuum cover. The outside diameter of the metal or plastic spray nozzle 1 is provided with the sealed vacuum cover 6 whose periphery is provided with a vacuum hole 7, the external side of the vacuum hole 7 is connected with a vacuum tube 8. A seal ring 9 is arranged between the spray nozzle 1 and the vacuum cover 6 which is tightly connected with a plate 3. The air in a die 5 is extracted through the vacuum hole 7. The utility model has the advantages of simple structure and easy operation, and solves the problems of that the vacuum extractor adopted by the metal and plastic die-casting technics has complex operation, high manufacturing cost, difficult maintenance, etc., and the service life of a vacuum pumping valve is short.
Description
Technical field
The utility model relates to metal, plastic hot die casting is penetrated and chewed, and particularly a kind of die-cast metal with the sealed vacuum cover, plastics are penetrated and chewed.
Background technology
The technology of die-cast metal and plastic products, one of difficult technologies is how to make not contain pore in metal, the plastic products.The present vaccum-pumping equipment of the process using of die-cast metal and plastic products complicated operation not only, it is short service life to vacuumize valve, and vaccum-pumping equipment involve great expense maintenance difficult.
Summary of the invention
The purpose of this utility model is at above-mentioned shortcoming, develops a kind of die-cast metal with the sealed vacuum cover, plastics are penetrated and chewed, and are simple in structure, easy to operate, solved the metal of die casting, the difficult problem that plastic products do not contain pore effectively.
The purpose of this utility model is achieved in that at metal or plastics penetrates the external diameter of chewing, and the sealed vacuum cover is set.The periphery of sealed vacuum cover is provided with more than one vacuum hole, and the vacuum hole outside is connected with vacuum tube.Sealed vacuum cover and penetrating is provided with sealing ring between chewing, and sealing ring is chewed slipper seal with penetrating.Sealed vacuum cover and machine plate are tightly connected, and machine plate and mould are tightly connected.
During use, vavuum pump is connected with vacuum tube, start vavuum pump, the air of mould inside is chewed the vacuum chamber that enters the sealed vacuum cover from the injection of mould, be drawn out of through vacuum hole, make mould inside realize vacuum after, penetrate the injection of chewing and chew slip to mould, inject to inject the front portion of chewing, metal or plastics are chewed the inside that enters mould and are cast product from penetrating to chew through injecting.
Because the utility model is simple in structure, easy to operate, solved the vaccum-pumping equipment complicated operation not only of the process using of metal and plastics die cast product effectively, it is short to vacuumize valve service life, and vaccum-pumping equipment involve great expense the difficult problem of maintenance difficult.
Accompanying drawing is described
Fig. 1 is the side-looking structural representation that the utility model combines with mould.
The specific embodiment
In conjunction with the accompanying drawings and embodiments, further describe structure of the present utility model.
Embodiment: hot chamber diecasting kirsite toy car mould
Penetrate at metal and to chew 1 external diameter, sealed vacuum cover 6 is set.The periphery of sealed vacuum cover 6 is provided with 2 vacuum holes 7, and vacuum hole 7 outsides are connected with vacuum tube 8.Sealed vacuum cover 6 and penetrate and be provided with sealing ring 9 between chewing 1, sealing ring 9 are chewed 1 slipper seal with penetrating.Sealed vacuum cover 9 is tightly connected with machine plate 3, and machine plate 3 is tightly connected with mould 5.
During use, vavuum pump is connected with vacuum tube 8, start vavuum pump, the air of mould 5 inside is chewed 4 vacuum chambers 10 that enter sealed vacuum cover 6 from the injection of mould 5, be drawn out of through vacuum hole 7, after making that mould 5 is inner and realizing vacuum, penetrate and chew 1 and chew 4 to the injection of mould 5 and slide, inject to inject and to chew 4 front portion, kirsite is chewed 1 internal diameter 2 and is chewed the 4 inside zinc die casting alloys toy car moulds that enter mould 5 through injecting from penetrating.
