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 matched moulds Machine guarding that the present invention relates to a kind of one-step plastic injection blowing hollow forming machine, belongs to plastics machinery field.
Background technology
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 debugging and the troubleshooting of machine and mould.Automatic and automanual mode of operation at the injection moulding of done state machine and blowing shuttering in die opening state, wait for that commissioning staff processes on-the-spot problem, now, two shutterings (moving platen) that must strict guarantee machine can not drop, otherwise may 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 adopts at mould die cylinder cavity of resorption, reaches the effect that stops shuttering (moving platen) tenesmus under inactive state.But in actual production, hydraulically-controlled one-way valve or balanced valve easily break down and cannot play a protective role to mold closing mechanism, staff's personal injury and mould damage are often caused.
Summary of the invention
The object of the invention is the shortcoming in order to overcome prior art; provide a kind of outside hydraulic protector; adopt again Machine guarding; in the time that hydraulic protector lost efficacy; still can stop the tenesmus of machine moving platen, make machine there is the protecting device for mold closing machine of plastic injection blow molding machine of dual matched moulds defencive function.
The technical scheme of protecting device for mold closing machine of plastic injection blow molding machine of the present invention is: comprise crossbeam and workbench; crossbeam is connected by column with workbench; installation mold counterdie on workbench; folding mould oil cylinder is installed in crossbeam; folding mould oil cylinder connects moving platen; connecting mold patrix under moving platen; upper mould is corresponding with lower mould; it is characterized in that mounting plate on described crossbeam; latch cylinder is laterally installed on fixed head; the piston rod connecting bolt of latch cylinder, the vertical hook of installing on moving platen, latch matches with hook.
Protecting device for mold closing machine of plastic injection blow molding machine of the present invention, when work, when an automatic cycle (injection moulding of machine, blowing process) enter manual mode, moving platen is in die opening state, now, control system of machine sends latch and enters instruction, latch cylinder drives latch to advance and is inserted among hook, if now the hydraulic protector of machine lost efficacy, moving platen will drive hook tenesmus together under the Action of Gravity Field of self and upper mould, because latch has inserted in hook, when hook tenesmus, hang on latch, latch has stoped the tenesmus of hook and moving platen, play a protective role.The Machine guarding of this programme uses together with hydraulic protector, and machine has dual matched moulds defencive function, guarantees staff's personal safety and mould safety.
Protecting device for mold closing machine of plastic injection blow molding machine of the present invention, is equipped with self-lubricating bearing in described fixed head, and self-lubricating bearing contacts with latch, has had self-lubricating bearing, the motion of latch is play the guiding role, and reduce friction.
Brief description of the drawings
Fig. 1 is that matched moulds Machine guarding latch of the present invention is in inserting view;
Fig. 2 is that matched moulds Machine guarding latch of the present invention is in exit status schematic diagram;
Fig. 3 is that the A of Fig. 1 is to schematic diagram.
Detailed description of the invention
The present invention relates to a kind of protecting device for mold closing machine of plastic injection blow molding machine, as shown in Figure 1-Figure 3, comprise crossbeam 1 and workbench 2, crossbeam is connected by column 3 with workbench, installation mold counterdie 4 on workbench 2, folding mould oil cylinder 5 is installed in crossbeam 1, folding mould oil cylinder 5 connects moving platen 6, 6 times connecting mold patrixes 7 of moving platen, upper mould 7 is corresponding with lower mould 4, it is characterized in that mounting plate 8 on described crossbeam 1, latch cylinder 9 is laterally installed on fixed head, piston rod 91 connecting bolts 10 of latch cylinder 9, the vertical hook 11 of installing on moving platen 6, latch 10 matches with hook 11.When work; when the automatic cycle (injection moulding, blowing process) of machine enters manual mode; moving platen 6 is in die opening state; now; control system of machine sends latch and enters instruction; latch cylinder 9 drives latch 10 to advance and is inserted among hook 11; if now the hydraulic protector of machine lost efficacy; moving platen 6 will drive hook 11 tenesmus together under the Action of Gravity Field of self and upper mould 7; because latch 10 has inserted in hook 11; hook 11 tenesmus when hang on latch 10, and latch 10 has stoped links up with 11 and the tenesmus of moving platen 6, plays a protective role.The Machine guarding of this programme uses together with hydraulic protector, and machine has dual matched moulds defencive function, guarantees staff's personal safety and mould safety.In described fixed head 8, be equipped with self-lubricating bearing 12, self-lubricating bearing 12 contacts with latch 10, has had self-lubricating bearing, the motion of latch is play the guiding role, and reduce friction.
