Abstract
The invention discloses equipment reformation of an injection molding machine for realizing repeated reciprocating neutron action. Hydraulic and control circuits are reformed on the basis of the conventional control elements on an ordinary injection molding machine, so that complex actions of neutrons can be realized. The equipment reformation is finished by reasonably matching a control system with a hydraulic or pneumatic system. The control system is used for providing an action signal, and the hydraulic or pneumatic system is used for providing power, so that the requirement on special action of linkage (performing neutron action during mold opening and closing) between advancing and retracting reciprocating actions of the neutrons and mold opening and closing can be realized on an ordinary injection molding machine. The work is stable, and the reformation cost is very low.

Technical field
The present invention relates to the device structure transformation of injection machine, be applied to while carrying out the check of injection mold with injection machine, there is special neutron action for some, as neutron not only enters but also move back, or opening mould assembling action and carrying out simultaneously the mould of neutron action, and common injection machine cannot complete these action requests, need to carry out the transformation of injection machine.
Background technology
The neutron action of common injection machine can only be in die sinking after certain position, under die sinking action halted state, carry out neutron and move back core; At matched moulds, to certain position, matched moulds stops, and neutron enters core, and, neutron forward and back core with open mould assembling action and can not link.
In addition, in common injection machine, general large-tonnage injection machine has three neutrons: neutron A, neutron B and neutron C, and the injection machine of little tonnage only has two neutrons, neutron A and neutron B.The position of their actions can be set in out, any point between mould closing section, but neutron A, B, C can not move simultaneously, can move in order, as three neutron action positions are arranged on same position, system default is that die sinking or matched moulds are after setting position, neutron A, B, the action of C sequencing, in the time of neutron population that independently moving cell provides more than injection machine, just cannot realize die trial requirement with common injection machine, and, common injection machine can not be realized in a process of die sinking or matched moulds, neutron not only enters but also move back, more cannot realize moving cell in a process enters, move back, enter again, the action of moving back again.When in a die sinking or matched moulds process, certain moving cell requires both entered and moved back, or forward and back, enter again, move back again action time, just must undergo technological transformation to common injection machine.
And in the mould exporting to foreign countries having, may run into unconventional action request, in die sinking, to certain position, neutron oil cylinder will first move back core, laggard core, move back the compound action of core again.For these special circumstances, in the situation that there is no special injection molding, must carry out appropriate reconstruction to common injection machine and just can reach motion requirement.
Summary of the invention
The problem to be solved in the present invention is to adopt existing control element on common injection machine by the transformation of hydraulic pressure and control circuit, can realize the compound action of above-mentioned neutron.
For addressing the above problem, the present invention realizes by following scheme: a kind of injection machine scrap build of repeatedly reciprocating neutron action, based on existing control element on common injection machine by the transformation of hydraulic pressure and control circuit, can realize the compound action of neutron, described scrap build is by incompatible the completing of Reasonable of control system and hydraulic pressure or pneumatic system, control system provides actuating signal, and hydraulic pressure or pneumatic system provide power.
Provide between power and neutron and finish the work by two oil cylinders, the oil circuit interface of second oil path in oil cylinder access neutron A, directly control the electric liquid reversing solenoid valve of neutron A with the electric-control system of neutron A, and then control entering core and moving back core of second oil cylinder, realize the contraposition of long core pin and short core pin, the oil circuit interface of first oil path in oil cylinder access neutron B, with the electric liquid reversing solenoid valve of the electric control system controls neutron B of neutron B, and then control entering for the first time core and moving back core of first oil cylinder, realize the advance and retreat action of long core pin.
