The invention discloses the rear mode structure of a kind of injection mold, including the mold cavity plate being cascading from top to bottom, rear mold core plates, rear core rod backing plate and transverse flow channels；Described mold cavity plate and rear mold core plates offer two symmetrical mold insert chambeies；The symmetrical crescent in described mold insert chamber, its crescent moon depression is relatively；Described mold insert chamber extends vertically through mold cavity plate and rear mold core plates；Said two mold insert chamber is positioned at the left and right sides of transverse flow channels；Two symmetrical submarine charging apertures it are further opened with in described mold cavity plate；The mold insert chamber of the left and right sides is connected by said two submarine charging aperture respectively with transverse flow channels；Two rear mold mold inserts it are inlaid with in described rear mold core plates；Described rear core rod backing plate uses hard metal to process, and increases hard material and prevent mold insert mould bases aborning deformation mold insert from retreating bottom mold insert.The rear mode structure of the present invention is used for injection mold, is used for producing crescent injecting products, and machining accuracy is high, and can produce two simultaneously, and working (machining) efficiency is high.
Description
Technical field
The present invention relates to plastic cement products mould structure field, after particularly relating to the injection mold of a kind of crescent die cavity
Mode structure.
Background technology
Injection mold is the important process equipment producing various industrial products, along with developing rapidly of plastics industry, and
Plastic is in the popularization and application of the industrial departments such as Aeronautics and Astronautics, electronics, machinery, boats and ships and automobile, and injection mold is extensively applied
In industry-by-industry.Traditional injection moulding mould is made up of dynamic model and cover half two parts, and dynamic model is arranged on the mobile mould of injection (mo(u)lding) machine
On plate, cover half is arranged on the fixed form of injection (mo(u)lding) machine.When injection moulding, dynamic model constitutes running gate system with cover half Guan Bi
And die cavity, during die sinking, dynamic model separates with cover half to take out plastic.The shape of some part can be more special, therefore at mould
Certain difficulty is had, it is necessary to reasonably design mould structure in tool design.
Summary of the invention
For the technical problem of above-mentioned existence, it is an object of the invention to: propose a kind of for being molded crescent part
The rear mode structure of injection mold.
The technical solution of the present invention is achieved in that the rear mode structure of a kind of injection mold, including from top to bottom
The mold cavity plate being cascading, rear mold core plates and rear core rod backing plate；Laterally stream is offered in the middle part of the top end face of described mold cavity plate
Road；Described mold cavity plate and rear mold core plates offer two symmetrical mold insert chambeies；The symmetrical crescent in described mold insert chamber,
Its crescent moon depression is relatively；Described mold insert chamber extends vertically through mold cavity plate and rear mold core plates；Said two mold insert chamber is positioned at transverse flow channels
The left and right sides；Two symmetrical submarine charging apertures it are further opened with in described mold cavity plate；Said two submarine feeds
The mold insert chamber of the left and right sides is connected by mouth respectively with transverse flow channels；Two rear mold mold inserts it are inlaid with in described rear mold core plates；Described
Rear core rod backing plate uses hard metal to process.
Preferably, described mold cavity plate and rear mold core plates are additionally provided with four dowel holes；Described dowel hole runs through die cavity
Plate and rear mold core plates.
Preferably, described four dowel holes are symmetrically distributed in upper and lower both sides, two mold insert chambeies two-by-two.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that
The rear mode structure of the injection mold of the present invention, is specifically designed for shape matching special crescent injecting products and designs, therefore
Mold insert chamber is designed as crescent, matches with crescent mold insert, the mold insert probability of damaging when assembling can be reduced to greatest extent,
And can be convenient to install, dismantle；And using submarine to feed, machining accuracy is high, and can produce two simultaneously, working (machining) efficiency
Height, and bottom mold insert, increase hard material prevent mold insert mould bases aborning deformation mold insert from retreating.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of the present invention；
Accompanying drawing 2 is the mold insert layout structure schematic diagram of the present invention；
In figure: 1, mold cavity plate；2, rear mold core plates；3, rear core rod backing plate；4, transverse flow channels；5, mold insert chamber；6, rear mold mold insert；7, fixed
Position pin-and-hole.
Detailed description of the invention
The present invention is described below in conjunction with the accompanying drawings.
The rear mode structure of the injection mold of the present invention, as shown in accompanying drawing 1-2, including the mould being cascading from top to bottom
Cavity plate 1, rear mold core plates 2 and rear core rod backing plate 3；Transverse flow channels 4 is offered in the middle part of the top end face of described mold cavity plate 1；Described die cavity
Plate 1 and rear mold core plates 2 offer two symmetrical mold insert chambeies 5；The symmetrical crescent in described mold insert chamber 5, its crescent moon
Depression is relatively；Described mold insert chamber 5 extends vertically through mold cavity plate 1 and rear mold core plates 2；Said two mold insert chamber 5 is positioned at transverse flow channels 4
The left and right sides；Two symmetrical submarine charging apertures (being not drawn in accompanying drawing) it are further opened with in described mold cavity plate 1；Described two
The mold insert chamber 5 of the left and right sides is connected by individual submarine charging aperture respectively with transverse flow channels 4；It is inlaid with two in described rear mold core plates 2
Individual rear mold mold insert 6；Described rear core rod backing plate 3 uses hard metal to process, and its effect is to increase hard material bottom mold insert to prevent
Only mold insert mould bases aborning deformation mold insert retreats.
Further illustrate, described mold cavity plate 1 and rear mold core plates 2 are additionally provided with four dowel holes 7；Described dowel hole 7
Running through mold cavity plate 1 and rear mold core plates 2, described four dowel holes 7 are symmetrically distributed in both sides, two mold insert chambeies about 5 two-by-two；By
Need to use slow silk thread cutting processing in mold insert chamber for precision height, by alignment pin by front core rod corresponding on mould before processing
Behind plate, mold cavity plate and three pieces of plate location of rear mold core plates, the slowest silk thread cutting processing puts in place, is prevented effectively from and rigging error occurs, can
Significantly improve its precision.
The rear mode structure of the injection mold of the present invention, is specifically designed for shape matching special crescent injecting products and designs,
Therefore mold insert chamber is designed as crescent, matches with crescent mold insert, mold insert damaging when assembling can be reduced to greatest extent
Probability, and can be convenient to install, dismantle；And using submarine to feed, machining accuracy is high, and can produce two simultaneously, adds
Work efficiency rate is high.
Above-described embodiment, only for technology design and the feature of the explanation present invention, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and is carried out, and can not limit the scope of the invention with this, all according to the present invention
The equivalence that spirit is made changes or modifies, and all should contain within the scope of the present invention.
