Description
Technical field
The utility model relates to a kind of transmission lock mold mechanism of three plate booster-type injection machines, belongs to field of plastic machinery.
Background technology
The kind of injection machine is a lot, wherein one is three-plate type, comprise front template, moving platen and rear pattern plate, rear pattern plate is installed folding mould oil cylinder, folding mould oil cylinder drives moving platen folding and locked mode through transmission lock mold mechanism, described transmission lock mold mechanism generally adopts elbow type, comprise the short elbow arm and long elbow arm that are connected to each other by intermediate pin, short elbow arm through after pin connect rear pattern plate, the premenstrual pin of long elbow arm connects front template, short elbow arm near intermediate pin one is shaped with connecting hole, connecting hole connects connecting rod through connecting pin, connecting rod connects leading truck, the piston rod of folding mould oil cylinder is connected on leading truck, thus drive short elbow arm and long elbow arm through leading truck and connecting rod, long elbow arm drives moving platen folding and locked mode, because the pressure needed during locked mode is very large, therefore the fulcrum (i.e. connecting pin) of connecting rod one of must try one's best near intermediate pin, just can play larger supporting role, make long elbow arm clamp force large, rely on the high pressure oil-feed that folding mould oil cylinder continues again, when injection mould closing injection moulding, effectively prevent mould to rise mould, reach the requirement of production technology, ensure product quality.But because fulcrum is close to one of intermediate pin, make the stroke distances of folding mould oil cylinder long, opposing mold to open closure pressing speed slow, and high-voltage lock mould energy consumption is large, and cost is high.Particularly piston rod and the tie point of leading truck are that sight alignment is parallel with two of leading truck to guide rod, and range ability is long, easily produce and rock, affect locked mode stability.On the other hand, the present inventor once devised a kind of two-plate injection machine, namely front template and moving platen is comprised, at front template or/and moving platen arranges pressuring plate, pressuring plate drives supercharging by pressurizing cylinder, and pressurizing cylinder is arranged between front template and pressuring plate, during work, rely on pressuring plate pressuring plate to produce locked mode effect to mould, prevent injection mold to rise mould.If booster-type template applied in three-plate type injection machine, after having had supercharging locked mode, folding mould oil cylinder only needs very little to try hard to recommend dynamic moving platen folding and locked mode, therefore, needs to design a kind of energy consumption low, stable transmission lock mold mechanism.
Summary of the invention
The purpose of this utility model is the shortcoming in order to overcome prior art, provides a kind of oil cylinder stroke short, and open closure pressing speed fast, production efficiency is high, and locked mode is reliable, the transmission lock mold mechanism of three stable plate booster-type injection machines.
The technical scheme of the transmission lock mold mechanism of the utility model three plate booster-type injection machine is: comprise front template, moving platen and rear pattern plate, the madial wall of front template arranges pressuring plate, pressuring plate is driven by pressurizing cylinder, the lateral wall of rear pattern plate is installed folding mould oil cylinder, the madial wall of rear pattern plate through after pin connect short elbow arm, short elbow arm connects long elbow arm through intermediate pin, the premenstrual pin of long elbow arm connects moving platen, it is characterized in that being shaped with supported hole in the short elbow arm of described close rear pin one, supported hole connects support bar through supporting pin, support bar connects bracing frame, described bracing frame is I shape, in the bracing frame corner of I shape, pilot hole is set, rear pattern plate installs four guide posts, four are passed four pilot holes separately to guide rod, the piston rod of folding mould oil cylinder is connected to the central point A place of I-shaped support frame.
The transmission lock mold mechanism of three plate booster-type injection machines of the present utility model; main feature is shaped with supported hole in the short elbow arm near rear pin one, the closer to rear pin position, more shortens the stroke of folding mould oil cylinder piston rod; relatively shorten folding mould distance, improve and open closure pressing speed.Meanwhile, owing to there being pressuring plate supercharging locked mode, make folding mould oil cylinder without high pressure oil-feed locked mode, save energy consumption.And bracing frame is I shape, in the corner of I-shaped support frame, pilot hole is set, guide post is through four pilot holes, piston rod is connected to the central point A place of I-shaped support frame, in four one center arrangement, operates steadily during work, guarantee that folding mould and locked mode are stablized, effectively prevent the mould that rises, ensure product quality, practicality is very strong.
The transmission lock mold mechanism of three plate booster-type injection machines of the present utility model, Connection Block before described moving platen is installed, connects ear before front Connection Block is arranged, and connects ear before the premenstrual pin of long elbow arm (11) connects.On described rear pattern plate install after Connection Block, rear Connection Block is arranged before connect ear, short elbow arm through after pin connection after connect ear.Forward and backward Connection Block can be assembled on moving platen and rear pattern plate separately, is beneficial to handling, safeguards, changes conveniently.The central point B of described intermediate pin is higher than the center line C of front pin and rear pin.When supercharging locked mode, the pressure that moving platen is subject to pressuring plate can be drawn back, by the center line C of the central point B of intermediate pin higher than front pin and rear pin, make intermediate pin outwards rise (arching upward) support long elbow arm, prevent moving platen from retreating, ensure that locked mode is reliable.
