Description
Technical field
The utility model relates to a kind of full electric injection molding machine, especially relates to the screw barrel replacing mechanism of a kind of use on full electric injection molding machine.
Background technology
In existing full electric injection molding machine, the basic skills of transposing screw barrel has two kinds (seeing accompanying drawing 4, accompanying drawing 5): 1. remove nozzle 10, semi-ring 22, then die sinking is to maximum, and screw rod 21 is extracted out or by contrary installation from machine barrel 20 is anterior.2. all hold-down screws of platform and corresponding protective plate and electrical equipment are penetrated in dismounting, then by the whole platform partial rotation of penetrating, remove nozzle 10, semi-ring 22, extract or press screw rod 21 out contrary installation from machine barrel 20 front portions.Yet because shaft coupling 70 and screw rod tail size are subject to the restriction of its structure, excessive versatility is poor, and causes dismounting difficulty in screw rod use procedure; The too small transmission that cannot guarantee the driving torque of major diameter screw rod, causes the inefficacy of undercapacity; Especially full electric injection molding machine minor diameter screw rod screw diameter transmitting torque in the majority, different is mutually far short of what is expected, so the tail dimension of some screw rod can be greater than the size of front end, now above-mentioned two kinds of traditional methods are all inapplicable but must remove hold-down screws all on machine barrel 20, fixed head 30 and corresponding protective plate and electrical equipment, screw rod 21 extracted out from machine barrel 20 rear portions or by contrary installation after whole machine barrel 20 is unloaded again.Operation is with contrary from the anterior habituation operation of extracting out of machine barrel by screw rod like this, exists and changes that different-diameter screw barrel is time-consuming, effort, versatility be poor, and operation sequence is loaded down with trivial details, and disassembling section program inconvenience, and efficiency is low.
Utility model content
Existing full electric injection molding machine is time-consuming at transposing different-diameter screw barrel in order to solve for the utility model, effort, versatility are poor, operation sequence is loaded down with trivial details, and disassembling section program is inconvenient, present situations such as efficiency is low and a kind of transposing different-diameter screw barrel of providing is easy to operate, easy, the screw barrel replacing mechanism of the full electric injection molding machine that efficiency is high.
The utility model is to solve the problems of the technologies described above adopted concrete technical scheme to be: a kind of screw barrel replacing mechanism of full electric injection molding machine, the machine barrel termination portion place that comprises machine barrel and be located at screw rod in machine barrel, screw front end direction is provided with nozzle, be located at fixed head and injection plate on line slideway, between injection plate and fixed head, be provided with shaft coupling, it is characterized in that: screw rod tail end is provided with the female key of screw rod, it is interior for the vias inner walls diameter dimension of screw rod is installed that screw rod tail end external diameter is less than machine barrel, and the female key of screw rod is connected with shaft coupling.The female key of screw rod tail diameter and screw rod cooperatively interacts, and improves the convenient and swift property that different-diameter screw rod is changed; Being less than screw front end size can improve to realize from barrel is anterior and extract out or by the convenient and swift property of contrary installation, disassembling, assembling and replacing operating efficiency is high simultaneously.
As preferably, the female key of described screw rod extends and is provided with annular boss in axial centre position, and annular boss is extreme direction before shaft coupling.Improve with shaft coupling the Stability and dependability connecting is installed.
As preferably, described screw rod tail diameter matches with the female key of screw rod.Improve the conformability of the female key of screw rod and screw rod, and then improve and change property convenient to operation.
As preferably, described screw rod tail end is provided with snap ring, and snap ring is located at that place, side end face of the female key of the screw rod reverse with annular boss.Improve the convenient and swift property of the installation dismounting transposing operation of screw rod tail end.
The beneficial effects of the utility model are: the female key of screw rod tail diameter and screw rod cooperatively interacts, and improves the convenient and swift property that different-diameter screw rod is changed; Being less than screw front end size can improve to realize from barrel is anterior and extract out or by the convenient and swift property of contrary installation, disassembling, assembling and replacing operating efficiency is high, time saving and energy saving simultaneously.
