Abstract
The utility model discloses a novel precise plastic mould which consists of a face plate and a bottom plate, wherein the face plate is provided with a movable template; the bottom plate is provided with a fixed template; two gas ejection devices are respectively arranged in the movable template and the fixed template; each gas ejection device comprises a gas ejection pipeline; the tail ends of the gas ejection pipelines are respectively communicated with the mould closing surfaces between the movable template and the fixed template; each gas ejection pipeline is internally provided with an ejector block, and one end of the ejector block is connected with a spring; each gas ejection pipeline is also communicated with a gas inlet pipe; a telescopic locating column is arranged at the bottom of the edge of the movable template, and a locating groove is arranged at the corresponding position of the bottom of the edge of the fixed template; an inclined plane is arranged at one side of the mould closing surface of the fixed template, and has the inclination angle of 15 degrees; a discharge cavity is formed by the space defined by the inclined plane and the bottom surface of the movable template; an exhaust hole is formed at one side of the mould closing surface at the lower part of the movable template, and the discharge cavity is communicated with the outside air by the exhaust hole; the exhaust hole is a horn-shaped hole, and the diameter of the exhaust hole is gradually increased from outside to inside. The novel precise plastic mould has the beneficial effect the structure of the exhaust hole is improved, so that the gas can be more smoothly and thoroughly discharged.
Description
Technical field
The utility model relates to a kind of precision plastic rubber mould of injection mo(u)lding.
Background technology
Injection molding technique is the method generally adopting in plastic processing, and during injection moulding, clamping mould is on injection machine, and molten plastic is injected in die cavity through flow passage system, and in die cavity cooling and shaping, then die sinking is ejected goods by ejection system in die cavity.In existing injection mold, ejection system structure is comparatively complicated, and the deviation of position and angle easily appears in location while installing, and during injection moulding, unnecessary molten plastic is inconvenient to discharge die cavity.
Utility model content
The purpose of this utility model is, overcomes the deficiencies in the prior art, proposes a kind of novel precise plastic mould.
The technical solution adopted in the utility model is as follows:
A novel precise plastic mould, is comprised of panel and base plate, and panel is provided with moving platen, and base plate is provided with solid plate; In moving platen and solid plate, be equipped with pneumatic jacking-up device, described pneumatic jacking-up device comprises pneumatic jack pipeline, and the end of pneumatic jack pipeline is communicated with the land area between moving platen and solid plate, in pneumatic jack pipeline, is provided with angled slide block, one end of angled slide block is connected with spring, and pneumatic jack pipeline is also communicated with air inlet pipe; In moving platen edge bottom, be provided with telescopic locating dowel, in solid plate edge bottom relevant position, be provided with locating slot; Solid plate is provided with inclined-plane in a side of land area, and the gradient on inclined-plane is 15 °, and the space between inclined-plane and moving platen bottom surface forms blowdown chamber; Moving platen bottom offers in a side of land area the steam vent that is communicated with blowdown chamber and outside air, and described steam vent is the flared hole that aperture expands from outside to inside gradually.
The beneficial effects of the utility model are, adopt pneumatic jacking-up device to replace traditional ejection system, and simple in structure, cost is lower; Add locating dowel and locating slot, make dynamic model and cover half when location, not only position is more accurate, and can, by regulating the height of both sides locating dowel, realize the adjusting of orientation angle; Set up blowdown chamber, unnecessary molten plastic has been discharged convenient; Vent structure has been made to improvement, more smooth and easy and thorough while making exhaust.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with specific embodiments and the drawings, the technical solution of the utility model is described further.
Referring to Fig. 1, precision plastic rubber mould, is comprised of panel 1 and base plate 2, and panel is provided with moving platen 3, and base plate is provided with solid plate 4; In moving platen and solid plate, be equipped with pneumatic jacking-up device 5, described pneumatic jacking-up device comprises pneumatic jack pipeline 51, and the end of pneumatic jack pipeline is communicated with the land area between moving platen and solid plate, is provided with angled slide block 52 in pneumatic jack pipeline, one end of angled slide block is connected with spring 53, and pneumatic jack pipeline is also communicated with 6 with air inlet pipe; In moving platen edge bottom, be provided with telescopic locating dowel 31, in solid plate edge bottom relevant position, be provided with locating slot 41.The gradient that solid plate is provided with 42， inclined-plane, inclined-plane in a side of land area is 15 °, and the space between inclined-plane and moving platen bottom surface forms blowdown chamber; Moving platen bottom offers in a side of land area the steam vent 32 that is communicated with blowdown chamber and outside air, and described steam vent is the flared hole that aperture expands from outside to inside gradually.
The utility model forms the die cavity of a sealing between moving platen and solid plate, when die sinking, utilizes pneumatic jacking-up device the goods in die cavity can be ejected.During location, by locating dowel is aimed to locating slot, embed, can improve the precision of location; By regulating the height of both sides locating dowel, the angle that can install land area regulates.During injection moulding, unnecessary molten plastic can be clamp-oned in blowdown chamber, discharges convenient.
To one skilled in the art, can make other various corresponding changes and deformation according to technical scheme described above and design, and within these all changes and deformation all should belong to the protection domain of the utility model claim.
