The specific embodiment
The utility model for traditional injection moulding mould in the many deficiencies aspect finished product mold insert, a kind of innovative evolutionary approach has been proposed, by introducing the formations mold insert modules such as cylinder and carry out electrification control in traditional moulds combination, thereby provide practicable technical solution for the integrated production of mold insert of injecting products.
As shown in Figures 2 to 4; it is the each several part structural representation of the injection mo(u)lding mechanism of the utility model slide block; comprise injection moulding main controller, lower die base 1, upper die base 2 and move back mould lifting body 4; and lower die base 1 is provided with counterdie core rod 31; upper die base 2 is provided with upper mould core 32, and upper and lower mold base is bonded into a corresponding die cavity with top shoe 7 when mold closing.As character of innovation; this injection mo(u)lding mechanism is provided with by thruster cylinder 5, pushes pin 51 and the mold insert module that forms of mold insert seat 52 in the embedding hole site of the corresponding slide block of lower die base; this thruster cylinder 5 is fixed in lower die base 1 outer wall; and push pin, 51 join with mold insert seat 52 one; this mold insert seat 52 is separated with die cavity and loads mold insert 6 under die opening state; and under mold closing state, driven in thruster cylinder 5 and moved towards die cavity, and make mold insert 6 and embedding hole 71 be bonded into one.
Especially; for improving working (machining) efficiency; the drive end access injection moulding main controller of thruster cylinder is (not shown; the main controller of general injection moulding machine is understood and grasped by those skilled in the art); and by program control this thruster cylinder of PLC can with the same sampling action of upper and lower mold base mold closing, i.e. thruster air cylinder driven mold insert seat feed motion during a mold closing injection moulding.
According to the need of production of slide block, can when processing, core rod slot for a plurality of slide blocks, thereby make corresponding one of die cavity, with top shoe, and corresponding each slide block of injection mo(u)lding mechanism is provided with one group of mold insert module, thereby can realize multi-slide injection molding, produced by insert molding simultaneously.In illustrated embodiment, this slide block 7 need to be implanted the mold insert 6 of two metals, and the corresponding a pair of slide block of the die cavity of a set of injection mo(u)lding mechanism, and be provided with two groups of mold insert modules.Each mold insert module, wherein each mold insert seat has two mold inserts loading positions, first completes the loading of two mold inserts, and then driven feeding after each mold closing.
During concrete enforcement, lower die base and upper die base are subject to the driving of injection moulding main controller and matched moulds, upper mould core and counterdie core rod form die cavity, then die cavity is carried out to injection moulding, after injection moulding completes, the thruster cylinder of inlaying module just starts, driving is pushed pin and is promoted mold insert seat, the embedding hole that mold insert seat embeds slide block by mold insert is integrated by joint both, then mold insert module resets and reloads mold insert, treat the thorough cooling forming of slide block, upper die base is driven separated with lower die base, and by moving back mould lifting body 4 by injection moulding Host Controller Driver again, the slide block of moulding is ejected, can obtain the perfect slide block product that embeds mold insert.
