Abstract
The invention discloses a front mold structure of an injection mold. The front mold structure comprises a front mold core backing plate, a front mold core plate and a main runner hole which are sequentially arranged from top to bottom in a stacking manner, wherein a transverse runner is arranged at the middle part of the bottom end surface of the front mold core plate; the main runner hole penetrates the front mold core backing plate and the front mold core plate and communicates with the transverse runner; two insert cavities which are bilaterally symmetrical are formed in the front mold core plate and vertically penetrate the front mold core plate; the insert cavities are bilaterally symmetrical and crescent, and the crescent concave parts of the insert cavities are face to face; the two insert cavities are positioned at the left and right sides of the transverse runner; two front mold inserts are inserted in the front mold core plate; the front mold core backing plate is manufactured from hard metals; and hard materials are arranged at the bottoms of the inserts to prevent the inserts from retreating due to deformation of a mold base in production. The front mold structure is applicable to the injection mold, is used for producing crescent injection products and is high in production accuracy, capable of producing two injection products at the same time and high in machining efficiency.
Description
Technical field
The present invention relates to plastic cement products mould structure field, particularly relate to the front mode structure of the injection mold of a kind of crescent die cavity.
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, injection mold is widely used 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 moving die plate of injection (mo(u)lding) machine, and cover half is arranged on the fixed form of injection (mo(u)lding) machine.When injection moulding, dynamic model constitutes running gate system and die cavity with cover half Guan Bi, and during die sinking, dynamic model separates with cover half to take out plastic.The shape of some part can be more special, therefore has certain difficulty on Design of Dies, it is necessary to reasonably design mould structure.
Summary of the invention
For the technical problem of above-mentioned existence, it is an object of the invention to: propose the front mode structure of a kind of injection mold for being molded crescent part.
The technical solution of the present invention is achieved in that the front mode structure of a kind of injection mould, including the front core rod backing plate being cascading from top to bottom and front mold core plates；The middle part of described front core rod backing plate and front mold core plates offers sprue hole；Transverse flow channels is offered in the middle part of the bottom face of described front mold core plates；Described sprue hole is run through front core rod backing plate and is connected with transverse flow channels with front mold core plates；Two symmetrical mold insert chambeies are offered in described front mold core plates；Described mold insert chamber extends vertically through front mold core plates；The symmetrical crescent in described mold insert chamber, its crescent moon depression is relatively；Said two mold insert chamber is positioned at the left and right sides of transverse flow channels；Two front mould mold inserts it are inlaid with in described front mold core plates；Described front core rod backing plate uses hard metal to process.
Preferably, described front mold core plates is additionally provided with four dowel holes.
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 front mode structure of the injection mould of the present invention, it is specifically designed for shape matching special crescent injecting products and designs, therefore mold insert chamber is designed as crescent, match 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 machining accuracy is high, can also produce two, working (machining) efficiency is high simultaneously, and increases hard material bottom mold insert and 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 front mould core plate structure schematic diagram of the present invention.
In figure: 1, front core rod backing plate；2, front mold core plates；3, sprue hole；4, transverse flow channels；5, mold insert chamber；6, front mould mold insert；7, dowel hole.
Detailed description of the invention
The present invention is described below in conjunction with the accompanying drawings.
The front mode structure of the injection mould of the present invention, as shown in accompanying drawing 1-2, including the front core rod backing plate 1 being cascading from top to bottom and front mold core plates 2；The middle part of described front core rod backing plate 1 and front mold core plates 2 offers sprue hole 3；Transverse flow channels 4 is offered in the middle part of the bottom face of described front mold core plates 2；Described sprue hole 4 is run through front core rod backing plate 1 and is connected with transverse flow channels 4 with front mold core plates 2；Two symmetrical mold insert chambeies 5 are offered in described front mold core plates 2；Described mold insert chamber 5 extends vertically through front mold core plates 2；The symmetrical crescent in described mold insert chamber 5, its crescent moon depression is relatively；Said two mold insert chamber 5 is positioned at the left and right sides of transverse flow channels 4；Two front mould mold inserts 6 it are inlaid with in described front mold core plates 2；Described front core rod backing plate 1 uses hard metal to process, and its effect is to increase hard material bottom mold insert to prevent mold insert mould bases aborning deformation mold insert from retreating.
Further illustrating, described front mold core plates 2 is additionally provided with four dowel holes 7, described four dowel holes 7 are symmetrically distributed in both sides, two mold insert chambeies about 5 two-by-two；Need to use slow silk thread cutting processing for precision height due to mold insert chamber, after front mold core plates being positioned with the mold cavity plate of mould and three blocks of plates of rear mold core plates by alignment pin before processing, the slowest silk thread cutting processing puts in place, it is prevented effectively from and rigging error occurs, be remarkably improved its precision.
The front mode structure of the injection mould of the present invention, it 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, and working (machining) efficiency is high.
Above-described embodiment is only for technology design and the feature of the explanation present invention; its object is to allow person skilled in the art will appreciate that present disclosure and to be carried out; can not limit the scope of the invention with this; all equivalence changes made according to spirit of the invention or modification, all should contain within the scope of the present invention.
