Abstract
The utility model relates to an injection mould ejection device which comprises a dynamic mould cavity, a dynamic mould board, a push rod fixing plate, a push plate, an upper ejection rod and a lower ejection rod. The dynamic mould cavity is fixed on the dynamic mould board by a screw; the lower ejection rod is fixed on the push rod fixing plate by the push plate; the section of the upper ejection rod is geometric; a through hole is arranged at the bottom end of the upper ejection rod; a groove and a through hole are arranged at the top end of the lower ejection rod; and the upper ejection rod is fixed in the groove of the lower ejection rod by a dowel. The injection mould ejection device has a simple structure, works steadily and is convenient to process, a deformed ejection rod is processed according to the shape of the product ejection position, and the stressed area of the ejection rod is large, so that the ejection action is easily completed. Therefore, the external surface of the plastic product is traceless, smooth and attractive, and the product appearance requirement can be met.
Description
Technical field
The utility model relates to the structure member in a kind of injection mold, relates in particular to a kind of injection mold liftout attachment.
Background technology
In injection moulding processing, what the mode that goods eject adopted in injection mold structure usually is: dome pin, flat thimble, ejector sleeve, push pedal etc.For the complicated thin-gage goods of some shapes, generally can select dome pin and flat thimble.Along with people constantly increase the demand of all kinds of thin wall plasticses, particularly communication product such as mobile phone requires to improve constantly to the small heteromorphosis and the appearance of plastics exterior trimming parts, and the traditional dome pin and the pushing method of flat thimble can't meet the demands.When 1, using the dome pin, because its available specification seldom, lifting surface area is less when ejecting, and product surface is easy to generate the pit phenomenon.When 2, using flat thimble structure, because the mold cavity that flat thimble is installed inevitably produces fillet adding man-hour corner, relatively be difficult to be processed into and the identical Nogata of flat thimble shape hole, so just make the gap that is combined with of flat thimble and mold cavity, and place, crack process time can form burr on goods, if use the cost that the flat thimble that has fillet has strengthened mould again instead.More than two kinds of methods all can exert an influence to the product surface outward appearance, thereby can't satisfy higher appearance requirement.3, also have the thin-gage goods shape of some structures complicated, should not arrange thimble, and adopt the mould structure of other modes can increase processing cost.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, a kind of ejecting structure that is applicable to complex-shaped thin-gage goods is provided, be specially adapted to not allow to arrange the product of push rod, the part identical with article shape is processed at the position that ejects of push rod separately, is fixed in again to finish on the push rod and ejects action.
For achieving the above object, the utility model adopts following technical scheme: a kind of injection mold liftout attachment, it is characterized in that: comprise dynamic model die cavity, moving platen, ejector pin retaining plate, push pedal, upper ejector pin, lower push rod, described dynamic model die cavity is fixed on the moving platen by screw, described lower push rod is fixed on the ejector pin retaining plate by push pedal, the cross section of described upper ejector pin is a geometric figure, the upper ejector pin bottom is provided with through hole, the lower push rod top is provided with groove and through hole, and upper ejector pin is fixed in the groove of lower push rod by pin.
The utility model is applicable to ejecting of special-shaped thin wall product, simple in structure, working stability, easy to process, special-shaped push rod is processed according to the shape that goods eject the position, and the push rod lifting surface area is big, finish easily and eject action, make the plastic products outer surface not have vestige, smooth, attractive in appearance, satisfy the product appearance demand.
Description of drawings
Fig. 1 is the push rod enlarged drawing;
Fig. 2 is the utility model structural representation.
Among the figure: 1, dynamic model die cavity, 2, moving platen, 3, ejector pin retaining plate, 4, push pedal, 6, upper ejector pin,
7, lower push rod.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in the figure, a kind of injection mold liftout attachment, comprise dynamic model die cavity 1, moving platen 2, ejector pin retaining plate 3, push pedal 4, upper ejector pin 6, lower push rod 7, dynamic model die cavity 1 is fixed on the moving platen 2 by screw, lower push rod 7 is installed in the push pedal 4, with screw ejector pin retaining plate 3 is fixed on below the push pedal 4, has finished lower push rod 7 and be fixed on the ejector pin retaining plate 3 by push pedal 4, this ejecting structure is the same with common thimble.Upper ejector pin 6 bottoms are provided with through hole, and lower push rod 7 tops are provided with groove and through hole, and upper ejector pin 6 is fixed in the groove of lower push rod 7 by pin.Upper ejector pin 6 is processed by linear cutting equipment, and its cross section geometric graphics shape is identical with the shape of the special-shaped thin wall that will eject goods.
After injection moulding was finished, when dynamic model die cavity 1 moved to respective distance along with moving platen 2, upper ejector pin 6 stretched out, and goods are ejected dynamic model die cavity 1, realized ejecting after the action, and dynamic model die cavity 1 is along with moving platen 2 travelling backwards, and upper ejector pin 6 resets, and waits for next process.
