Description
Technical field
The utility model relates to a kind of vacuum wax injection machine vapour-pressure type wax injection valve body structure.
Background technology
The vacuum wax injection machine that on domestic market, jewellery manufacturer uses, valve body structure is all adopt electromagnetic actuation, vacuumize casting, retracting spring return seals, when the voltage is high, electromagnet coil easily burns, when voltage is low, electromagnet can not adhesive, casting cannot be vacuumized, also exist slow in one's movements with spring force sealing, when valve rod resistance is large, wax is leaked in generation or wax stream does not stop, severe contamination working environment, workman is damaged, valve body wax circulation road right-angle turning, cause the casting pressure loss large, it is discontented that wax-pattern produces overlap note, the defects such as gas foam.
Utility model content
The purpose of this utility model is for above weak point, provides a kind of vacuum wax injection machine vapour-pressure type wax injection valve body structure.
The scheme that the utility model technical solution problem adopts is, a kind of vacuum wax injection machine vapour-pressure type wax injection valve body structure, comprise and offer vacuum passage, enter the main valve body in wax passage and storage wax chamber, described main valve body comprises valve body matrix, the wax injection nozzle being arranged on the connecting plate on the upside of valve body matrix and being arranged on front side of valve body matrix, described connecting plate and wax injection nozzle are all fixedly connected with valve body matrix, connecting plate is provided with into wax mouth and vacuum orifice, described valve body matrix inside is provided with casting piston rod and vacuum cock bar, the axis of described casting piston rod and the axis perpendicular of vacuum cock bar, described enter wax passage with storage wax chamber be connected, described casting piston rod is arranged in storage wax chamber, described casting piston rod is by the casting air cylinder driven being arranged on valve body matrix rear portion, described vacuum cock bar is driven by the vacuum cylinder be arranged on the left of valve body matrix, described wax injection nozzle offers and the casting nozzle storing up wax chamber and communicate, described wax injection nozzle inside offers the air exhaust duct be connected with vacuum passage, described air exhaust duct is connected with casting nozzle, described casting piston rod front end and vacuum cock bar front end are provided with rigid seal block, baton round check valve is provided with in described air exhaust duct.
Further, described casting cylinder and vacuum cylinder are all connected with valve body matrix by contiguous block, and described contiguous block inside is provided with the sealing ring matched with casting piston rod or vacuum cock bar.
Compared with prior art, the utility model has following beneficial effect: structure adopts Z-type channels designs, wax flow distance is short, nozzle adopts conical structure, nozzle and storage wax chamber are through type passages, injection pressure loss is little, when casting is produced, use low-pressure casting, far firing range, decrease wax-pattern overlap and bubble, improve yield rate, vacuum pipe there is baton round check valve, significantly decrease the storage of vacuum pipe length and wax, when wax machine does not work, during without air pressure, seal with spring force, when connecting upper air pressure, the thrust of cylinder, promote piston rod and rigid seal fast, compression seal face, movement response is sensitive rapidly, sealing does not reliably leak wax, effectively prevent poorly sealed ceaselessly wax spray, cause the injury to workman.
