Description
Technical field
The present invention relates to workpiece detection technique field, be specifically related to a kind of optical glass die casting equipment.
Background technology
Along with optical device, instrument widely use society's every field, the high demand of joining of optical glass increases rapidly, and the die casting of the first operation lens blank as optical glass processing, mostly continue to use traditional drawing method, namely with mould pieces compacting on forcing press, although have employed various Automated condtrol measure at present, but still have problems and defect.Its main manifestations: 1) it is that former material bar is cut off in advance, heats to molten condition mostly, single-piece is transferred in compacting tool set and suppresses, not only cut time-consuming taking a lot of work, and movement is manually with clamp specially clamping transport, bad operation, screen is slow, and safety coefficient is relatively low, thus bring production efficiency low, it is easy to personal injury accident occurs；2) compressing later needs of eyeglass cools down rear energy molding with mould, take presser's bit time long, in order to shorten cool time, the methods adopting pressure-air to force rapid cooling at present more, this cooling means is very big to eyeglass internal crystal framework tissue effect, causes that the optical property of eyeglass declines；3) in the process of compacting continuously, pressure head and liquid cylinder piston bar temperature raise, sometimes even close to melted blank temperature, piston rod is caused to expand, decrease in strength, it is easy to the phenomenons such as deformation, locking occur, affecting fluid cylinder service life, fault rate is high, also affects Die Casting efficiency because frequently keeping in repair.Such as the problems referred to above not yet obtain ideal solution so far.
Summary of the invention
To be solved by this invention it has a problem in that the drawbacks described above overcoming prior art, it is provided that a kind of die casting equipment that can be effectively improved optical glass production efficiency and quality.
For solving above-mentioned technical problem, the technical solution used in the present invention is: a kind of optical glass die casting equipment, including forcing press, die casting and multistation switching device, die casting is made up of upper mould and multiple counterdie, upper mould is connected to press ram lower end, and counterdie is separately mounted on each station of multistation switching device.
Described multistation switching device includes base and die holder, die holder is connected with base turn by central shaft, it arranges several die casting stations that can switch, cooling station and stripper station, die casting station, cooling station and stripper station connect described counterdie respectively through rotating shaft, and described central shaft connects servomotor by driving member.
Described rotating shaft is connected to the action bars for overturning counterdie.
