Utility model content
In order to solve the technical problem existed in background technology, the utility model proposes a kind of injection mold of being excused from a college course burr, shortening the production cycle of product, reducing the labour intensity of operator, improve production efficiency.
A kind of injection mold of being excused from a college course burr that the utility model proposes, comprise moving platen, solid plate, guide post and mould emptier, moving platen, solid plate is oppositely arranged and is connected by many guide posts, moving platen, the die joint of solid plate is respectively equipped with dynamic model core rod mold insert, cover half core rod mold insert, dynamic model core rod mold insert has and arranges chamber more, dynamic model core rod mold insert offers dynamic model injection molding channel, moving platen is provided with the cast passage be communicated with dynamic model injection molding channel, dynamic model core rod mold insert is provided with the through hole being communicated with chamber and dynamic model injection molding channel, from dynamic model injection molding channel to chamber, the diameter of through hole reduces gradually, the cutter being positioned at through hole edge is provided with in chamber, cover half core rod mold insert have the core rod corresponding with arranging chamber more, cover half core rod mold insert offers the cover half injection molding channel corresponding with dynamic model injection molding channel, moving platen during matched moulds, the die joint of solid plate is in the same plane, core rod inserts the die cavity that chamber forms shaping plastic, mould emptier is arranged on moving platen, after plastic parts moulding, mould emptier ejects the plastic on dynamic model core rod mold insert, in chamber, plastic is cut off by through hole edge cutter simultaneously.
Preferably, moving platen is provided with the cooling system cooled plastic in chamber.
Preferably, the diameter of through hole near dynamic model injection molding channel side is through hole near 1 ~ 5 times of chamber side diameter.
Preferably, the degree of depth of dynamic model injection molding channel is the degree of depth 1 ~ 1.5 times of cover half injection molding channel.
Preferably, the spacing between dynamic model injection molding channel and chamber is 3 ~ 8mm.
A kind of injection mold of being excused from a college course burr that the utility model provides; adopt the hiding through hole be provided with on moving platen with dynamic model injection molding channel and chamber; from dynamic model injection molding channel to chamber, the diameter of through hole reduces gradually; the cutter being positioned at through hole edge is provided with in chamber; when the demoulding; mould emptier ejects between the active force of plastic in chamber and the cutter at through hole edge and forms shearing force; not only can cut off the plastic in plastic and runner in chamber; the cutting edge of cutter is contrary with the direction of shearing force, reaches the pruning of plastic burr.The utility model adopts through hole large near patrix injection molding channel side diameter, and little near chamber side diameter, make shearing force preferentially cut off chamber side, the plastic in through hole is gone out by plastic one passband in patrix injection molding channel; The length of through hole adopts 3 ~ 8mm, avoids plastic residual in through-holes.The utility model structure is simple, shortens the production cycle of product, reduces the labour intensity of operator, improve production efficiency.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of being excused from a college course the injection mold of burr that the utility model proposes.
Detailed description of the invention
As shown in Figure 1, Fig. 1 is a kind of structural representation of being excused from a college course the injection mold of burr that the utility model proposes.
With reference to Fig. 1, a kind of injection mold of being excused from a college course burr that the utility model proposes, comprise moving platen 1, solid plate 2, guide post 3 and mould emptier, moving platen 1, solid plate 2 is oppositely arranged and is connected by many guide posts 3, moving platen 1, the die joint of solid plate 2 is respectively equipped with dynamic model core rod mold insert, cover half core rod mold insert, dynamic model core rod mold insert have many row's chambers 11, dynamic model core rod mold insert offers dynamic model injection molding channel 12, moving platen 1 is provided with the cast passage 13 be communicated with dynamic model injection molding channel 12, dynamic model core rod mold insert is provided with the through hole 14 being communicated with chamber 11 and dynamic model injection molding channel 12, from dynamic model injection molding channel 12 to chamber 11, the diameter of through hole 14 reduces gradually, the cutter being positioned at through hole 14 edge is provided with in chamber 11, cover half core rod mold insert have the core rod 21 corresponding with arranging chamber more, cover half core rod mold insert offers the cover half injection molding channel 22 corresponding with dynamic model injection molding channel 12, moving platen 1 during matched moulds, the die joint of solid plate 2 is in the same plane, core rod 12 inserts the die cavity that chamber 11 forms shaping plastic, dynamic model injection molding channel 12, cover half injection molding channel 22 forms injection molding channel, the molten plastic entering injection molding channel from cast passage 13 to be entered in die cavity by through hole 14 and is full of, mould emptier is arranged on moving platen 1, moving platen 1 is provided with the cooling system cooled plastic in chamber 11.After plastic parts moulding, mould emptier ejects the plastic on dynamic model core rod mold insert, and in chamber 11, plastic is cut off by through hole 14 edge cutter simultaneously.The utility model whole knockout course operating efficiency is high and the demoulding is smooth and easy, realizes the pruning of plastic burr simultaneously, reduces the labour intensity of operator, improves operating efficiency, reduce production cost.
