Abstract
The invention provides a mechanical protection device for a die assembly of a plastic injection and blowing molding machine, comprising a cross beam and a worktable, wherein the cross beam is connected with the worktable through a stand column; the worktable is provided with a lower die of a mounting mould and the cross beam is internally provided with an opening/closing die air cylinder; the opening/closing die air cylinder is connected with a movable template and an upper die of the mould is connected below the movable template; the upper die of the mould corresponds to the lower die of the mould; the mechanical protection device provided by the invention is characterized in that: the cross beam is fixedly provided with a fixed plate and the fixed plate is transversely provided with a plug air cylinder; a piston rod of the plug air cylinder is connected with a plug and a hook is vertically arranged on the movable template; and the pin is matched with the hook. The mechanical protection device provided by the invention is matched with a hydraulic protection device of a machine so that the machine has double die assembly protection functions, and the personal safety of workers and the mould safety are ensured.
Description
Technical field
The present invention relates to a kind of matched moulds Machine guarding of one-step method plastic injecting and blowing blow moulding machine, belong to the plastics machinery field.
Background technology
The one-step injection blower blow moulding machine has two man of great strengths' mold closing mechanism, i.e. injection moulding matched moulds and blowing matched moulds.This machine has automatic, semi-automatic and manual three kinds of mode of operations, and manual work pattern is mainly used in the debugging and the troubleshooting of machine and mould.Automatic and automanual mode of operation is in die opening state at the injection moulding and the blowing matched moulds plate of done state machine; Wait for that the commissioning staff handles on-the-spot problem; At this moment; Two matched moulds plates (moving platen) that must the strict guarantee machine can not drop, otherwise possibly cause commissioning staff's personal injury, and the plug of mold damage.Therefore, it is that rod chamber connects hydraulically-controlled one-way valve or balanced valve that prior art is employed in mould die cylinder cavity of resorption, reaches the effect that stops matched moulds plate (moving platen) tenesmus under the inactive state.But in actual production, hydraulically-controlled one-way valve or balanced valve break down easily and can't play a protective role to mold closing mechanism, have often caused the damage of staff's personal injury and mould.
Summary of the invention
The objective of the invention is in order to overcome the shortcoming of prior art; Provide a kind of outside hydraulic protector; Adopt Machine guarding again; When hydraulic protector lost efficacy, still can stop the tenesmus of machine moving platen, make machine have the plastic injecting and blowing make-up machine matched moulds Machine guarding of dual matched moulds defencive function.
The technical scheme of plastic injecting and blowing make-up machine matched moulds Machine guarding of the present invention is: comprise crossbeam and workbench, crossbeam is connected by column with workbench, installation mold counterdie on the workbench; The folding mould oil cylinder is installed in the crossbeam, and the folding mould oil cylinder connects moving platen, and moving platen connects upper mould down; Upper mould is corresponding with lower mould; It is characterized in that mounting plate on the described crossbeam, the latch cylinder laterally is installed on the fixed head, the piston rod of latch cylinder connects latch; The vertical hook of installing on moving platen, latch matches with hook.
Plastic injecting and blowing make-up machine matched moulds Machine guarding of the present invention is during work, when Automatic Cycle (injection moulding, blowing process) the entering manual state of machine; Moving platen is in die opening state, and at this moment, control system of machine sends latch and advances instruction; The latch cylinder drives latch and advances and be inserted among the hook, and this moment was if the hydraulic protector of machine lost efficacy, and moving platen will drive down to link up with together in the gravity effect of self and upper mould and drop; Because latch has inserted in the hook; Hang on the latch during hook tenesmus, latch has stoped the tenesmus of hook and moving platen, plays a protective role.The Machine guarding and the hydraulic protector of this programme use together, and machine has dual matched moulds defencive function, guarantee staff's personal safety and mould safety.
Plastic injecting and blowing make-up machine matched moulds Machine guarding of the present invention is equipped with self-lubricating bearing in the described fixed head, and self-lubricating bearing contacts with latch, and self-lubricating bearing has been arranged, and the motion of latch is play the guiding role, and reduce friction.
Description of drawings
Fig. 1 is that matched moulds Machine guarding latch of the present invention is in the insertion view;
Fig. 2 is that matched moulds Machine guarding latch of the present invention is in the exit status sketch map;
Fig. 3 is that the A of Fig. 1 is to sketch map.
The specific embodiment
The present invention relates to a kind of plastic injecting and blowing make-up machine matched moulds Machine guarding,, comprise crossbeam 1 and workbench 2 like Fig. 1-shown in Figure 3; Crossbeam is connected by column 3 with workbench, and installation mold counterdie 4 on the workbench 2 is installed folding mould oil cylinder 5 in the crossbeam 1; Folding mould oil cylinder 5 connects moving platen 6, and moving platen connects upper mould 76 times, and upper mould 7 is corresponding with lower mould 4; It is characterized in that mounting plate 8 on the described crossbeam 1, latch cylinder 9 laterally is installed on the fixed head, the piston rod 91 of latch cylinder 9 connects latch 10; The vertical hook 11 of installing on moving platen 6, latch 10 matches with hook 11.During work, when Automatic Cycle (injection moulding, blowing process) the entering manual state of machine, moving platen 6 is in die opening state; At this moment, control system of machine sends latch and advances instruction, and latch cylinder 9 drive latches 10 advance and are inserted among the hook 11; This moment was if the hydraulic protector of machine lost efficacy; Moving platen 6 will drive hook 11 tenesmus together under the gravity effect of self and upper mould 7, because latch 10 has inserted in the hook 11, hang on the latch 10 during hook 11 tenesmus; Latch 10 has stoped links up with 11 and the tenesmus of moving platen 6, plays a protective role.The Machine guarding and the hydraulic protector of this programme use together, and machine has dual matched moulds defencive function, guarantee staff's personal safety and mould safety.Be equipped with self-lubricating bearing 12 in the described fixed head 8, self-lubricating bearing 12 contacts with latch 10, and self-lubricating bearing has been arranged, and the motion of latch is play the guiding role, and reduce friction.
