Abstract
The utility model discloses an ejection structure of an automotive plastic die. The ejection structure comprises a die core, a die plate A (60) and a die plate B (70), wherein a fixed die cavity (30) and a movable die cavity (20) are arranged on the die plate A (60), a wedge block (51) is arranged at the bottom of the movable die cavity (20), a locking component (52) is arranged on the wedge block (51), and a pneumatic ejection structure (10) is arranged at the contact part between the top of the movable die cavity (20) and the fixed die cavity (30). According to the ejection structure of the automotive plastic die, in the ejection process of a product, the smooth ejection, the smooth demolding and the uneasy deformation are guaranteed, the poor phenomenon such as ejector mark of the product and the like do not occur, and the smoothness of the demolding of a deep-cavity product is improved.
Description
Technical field
The utility model relates to a kind of mould of plastics, especially relates to the mould of plastics ejecting structure that some have the automobile plastic goods of dark cavity configuration.
Background technology
In the automobile plastic mould, usually can run into the dark chamber of some tubulars or rectangle product, for the dark chamber of this class product, if adopt more traditional ejecting structure, do ejecting structure such as independent thimble or pushing block, then be to guarantee to produce qualified product, it is white or ejecting the defect problem such as middle generation distortion product top often can to occur; And darker because of the die cavity of mould, when ejecting, can produce vacuum phenomenon, and then cause product demoulding difficult problem to occur.
The utility model content
To exist easy appearance top white or in a kind ofly the ejecting smoothly of providing such as the defect problem present situation that ejects middle generation distortion, the smoothly demoulding, not yielding in order to solve the existing automobile plastic goods that have a dark cavity configuration for the utility model, the white automobile plastic mold ejection structure in product top can not occur.
The utility model is to solve the problems of the technologies described above the concrete technical scheme that adopts to be: a kind of automobile plastic mold ejection structure, comprise the mould die, mould A plate and mould B plate, it is characterized in that: mould A plate is provided with cover half die cavity and dynamic mould core, the dynamic mould core bottom is provided with wedge block, wedge block is provided with locking member, is provided with pneumatic ejecting structure at dynamic mould core top and cover half die cavity contact position.Pneumatic ejecting structure more can guarantee to eject smoothly, the smoothly demoulding, not yielding in the process that dark chamber product ejects, and the bad phenomenon such as the product top is white can not occur.
As preferably, described locking member adopts lock screw or clamping screw.Installing/dismounting is easy to maintenance.
As preferably, the height of described dynamic mould core is for lengthening height.Reduce the difficulty when producing assembling.
As preferably, described dynamic mould core is provided with mounting groove, and pneumatic ejecting structure is located in the mounting groove.Reliable effectively mounting limit is fixed on the mounting groove.
As preferably, described dynamic mould core bottom is externally connected to push pedal.Increase the balance of dynamic mould core ejecting force.
As preferably, described cover half die cavity is provided with a plurality of air admission holes.Better air is introduced mould, improve the fairness of the demoulding.
As preferably, described mould B plate is provided with air admission hole.Better air is introduced mould, improve the fairness of the demoulding.
The beneficial effects of the utility model are: in the process that product ejects, more can guarantee to eject smoothly, the smoothly demoulding, not yielding, the bad phenomenon such as the product top is white can not occur, improve the fairness of dark chamber product stripping.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the preferred embodiment of the utility model automobile plastic mold ejection structure.
The specific embodiment
Among the embodiment shown in Figure 1, a kind of automobile plastic mold ejection structure, comprise the mould die, mould A plate 60 and mould B plate 70, mould A plate 60 is provided with cover half die cavity 30 and dynamic mould core 20, dynamic mould core 20 bottoms are provided with wedge block 51, and wedge block 51 is provided with locking member 52, are provided with pneumatic ejecting structure 10 at dynamic mould core 20 tops and cover half die cavity 30 contact positions.Locking member 52 adopts lock screw or clamping screw.The height of dynamic mould core 20 is for lengthening height, and is higher than the dynamic mould core of routine.Dynamic mould core 20 is provided with mounting groove 32, and pneumatic ejecting structure 10 is installed in the mounting groove 32.Dynamic mould core 20 bottoms are externally connected to push pedal 50, and cover half die cavity 30 is provided with a plurality of air admission holes 33.Mould B plate 70 is provided with air admission hole 33.
During use, during the mould die sinking, produce power by injection machine, the pulling dynamic mould core is done the die sinking action, mould reach set apart from the time stop motion, when described push pedal was done under the drive of oil hydraulic cylinder and ejected action, the compressed air valve was opened, pneumatic ejecting mechanism is done under compressed-air actuated effect and is ejected action, discharge the air of die cavity, when the oil hydraulic cylinder in the pneumatic ejecting mechanism finish set eject apart from the time, take out smoothly product, oil hydraulic cylinder drives push pedal and does homing action, the compressed air air valve is closed, and the pneumatic spring that ejects accessory inside resets under the effect of spring force, finish mould assembling action, continue to do next loop cycle action.
Although this paper has more used the terms such as cover half die cavity, dynamic mould core, pneumatic ejecting structure; But do not get rid of the possibility of using other term.Using these terms only is in order to describe more easily and explain essence of the present invention; They are construed to any additional restriction all is contrary with spirit of the present invention.
