Description
Technical field
The utility model relates to a kind of electronic product casing shaped device, is specifically related to a kind of based on electronic product casing automatic forming device fervent in mould.
Background technology
Most electronic product casing is adopted made of plastic, and the general mode of injection moulding that adopts realizes the shaping of electronic product casing.Along with the variation of electronic product function, the through-hole structure at its shell position constantly increases, as shooting head bore, charging hole, speaker hole, memory hole clipping etc.In prior art, mainly contain and need the position forming through hole that the mold insert of through die cavity is set in die cavity, the position at mold insert place cannot be filled due to PUR during injection moulding and leave a blank, after cooling, forming through hole.In the above prior art, PUR is filled to the position of mold insert, stop by mold insert and be divided into two strands of PUR fluids, need to detour from the both sides of mold insert, finally converge at the rear of mold insert, complete the filling to die cavity.And in the process of injection moulding, the temperature of PUR easily declines, two strands of PURs of convergence really cannot merge and form weld bond, and weld bond position easily becomes stress concentration point, reduce the mechanical strength of electronic product casing.
For avoiding the formation of weld bond, general way is the temperature that improves in die cavity and extends temperature retention time, promotes that the PUR that mold insert rear is converged fully mixes.This way adds the production cost of product, raises energy consumption and extends manufacture cycle.Now also have a kind of technology, it does not arrange the mold insert for the formation of through hole in die cavity, but carries out CNC processing to product after moulding, gets out through hole.This way effectively can avoid the formation of weld bond, but production efficiency is lower, and CNC equipment cost is higher, is difficult to production control cost.
Therefore, a kind of electronic product casing shaped device avoiding the formation of weld bond, efficiently can form through hole is needed badly.
Utility model content
In view of this, therefore the open one of the utility model, needs a kind of electronic product casing shaped device avoiding the formation of weld bond, efficiently can form through hole badly.
The purpose of this utility model is achieved through the following technical solutions: a kind of based on electronic product casing automatic forming device fervent in mould, comprise injection mold block, described injection mold block comprises lower bolster, cope match-plate pattern successively, the top of lower bolster is provided with at least one male model core, the bottom of cope match-plate pattern is provided with the master mold core mated with male model core, male model core closes up formation die cavity with corresponding master mold core, it is characterized in that: need inwall place corresponding to the position of formation through hole to be provided with at least one extended pore-forming cutting knife running through die cavity in described die cavity; Also comprise the cutter driving module driving pore-forming cutting knife to stretch and the die cavity driver module driving die cavity folding.
Described lower bolster, cope match-plate pattern, male model core, master mold core all can select any one existing techniques in realizing.The utility model arranges the pore-forming cutting knife that can stretch in die cavity, can run through die cavity and offset with the mould intracavity wall of relative position when pore-forming cutting knife stretches out, and then can be retracted in mould intracavity wall after contraction.When injection moulding, in pore-forming cutting knife retraction inwall, PUR can unimpededly be filled in die cavity; After filling, cutter driving module is ordered about pore-forming cutting knife and is stretched out, and will need the PUR cutting forming lead to the hole site, after cooling, cutting knife is retracted, and this position then forms complete through-hole structure.Technology fervent in this film effectively can avoid the formation of weld bond, raises mould temperature simultaneously or postpones temperature retention time, be conducive to reducing energy consumption without the need to the extra consumption energy; Namely the utility model can form through-hole structure by an injection moulding, effectively can shorten the production cycle, enhance productivity.
Further, described cutter driving module comprises and is arranged on cutter cylinder outside die cavity, the pressing plate be connected with cutter cylinder piston rod, is arranged on rear board inside pressing plate; The end of described pore-forming cutting knife penetrates the inwall of described die cavity and is vertically fixed on inside rear board.
The utility model selects the action of hydraulic oil cylinder driving pore-forming cutting knife especially.After being filled PUR in die cavity, there is higher interior pressure, need great power that pore-forming cutting knife can be driven to stretch in die cavity and complete fervent action.Relative to other devices, oil cylinder can provide enough pressure to order about pore-forming cutting knife and enter in die cavity and complete earnestly; The feature that simultaneously operation stability that has of oil cylinder itself is high, is also conducive to improving the thru-hole quality earnestly formed, and avoids because of the shake of pore-forming cutting knife, does not run through the problems such as die cavity completely and cause problem such as through hole generation burr, burr etc.Pressing plate can transmit power between pore-forming cutting knife and oil cylinder, is applied to fifty-fifty on pore-forming cutting knife by the pressure of cutting knife, is conducive to improving fervent effect, and strengthens the smoothness of action.The effect of rear board is
