Description

Injection mold

Technical field

The utility model relates to a kind of mould, relates in particular to an injection mold.

Background technology

In the existing injection mold field, under the situation when on the shaped article inwall, barb being arranged, generally all solve this type of technical problem by setting up the oblique top pin.

Yet setting up the oblique top pin on injection mold can increase ejection stroke usually, increases the area of injection mold, increases production cost, is unfavorable for enhancing productivity.

The utility model content

The purpose of this utility model is to provide a kind of injection mold that makes the smooth demoulding of product and enhance productivity.

For achieving the above object, injection mold that the utility model provides comprise a cover half, one with dynamic model and at least one ejecting mechanism of the corresponding setting of cover half; Cover half is provided with at least one release link; This dynamic model comprises a moving platen, one and a corresponding ejector retainner plate of moving platen and a core that is installed on the moving platen, and moving platen is provided with at least one accepting groove, is concaved with at least one inclined hole on the core; Ejecting mechanism is installed on the moving platen, ejecting mechanism comprises push rod, a jacking block and an angle ejector rod always, straight push rod one end is fixed on the ejector retainner plate, the straight push rod other end is resisted against the jacking block lower end, jacking block is contained in the accepting groove, angle ejector rod one end and jacking block are fixedly linked, the angle ejector rod other end convexes with a hook portion to a side, angle ejector rod is inserted in the inclined hole of core slidably and stretches out in core, hook portion can surround the die cavity of a shaped article barb with core, cover half end face, and release link is resisted against jacking block movably.

As mentioned above, the utility model injection mold is provided with ejecting mechanism by dynamic model, and then when having barb on the product inwall, uses the angle ejector rod of ejecting mechanism to eject simultaneously in the horizontal direction with on the vertical direction, thereby make the smooth demoulding of product, to enhance productivity.

As further improvement, moving platen is provided with at least one through hole.

The specific embodiment

By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.

See also Fig. 1 and Fig. 2, the utility model injection mold 1 comprises that a dynamic model 10, a cover half 20 and two are fixed in the ejecting mechanism 30 on the dynamic model 10.

Dynamic model 10 comprises that a dynamic mould fixing plate 11, a moving platen 12, an ejector retainner plate 13, a thimble fixed head 14, some thimbles 15 and are installed in the core 16 on the moving platen 12.Dynamic mould fixing plate 11 tops are provided with thimble fixed head 14, then be installed with ejector retainner plate 13 on the thimble fixed head 14, and above ejector retainner plate 13 moving platen 12 that is provided with separated by a distance, make the displacement between dynamic mould fixing plate 11 and moving platen 12 of ejector retainner plate 13 and thimble fixed head 14.Moving platen 12 is provided with two accepting grooves 121 and two through hole 122, and through hole 122 is communicated with accepting groove 121.Thimble 15 is fixed on the ejector retainner plate 13.Be concaved with two inclined holes 161 on the core 16, inclined hole 161 up/down perforation cores 16.

Described cover half 20 comprises that a cover half fixed head 21, a solid plate 22, certain die 23 and two are installed in the release link 24 on the cover half benevolence 23, and solid plate 22 is fixed on the cover half fixed head 21, and cover half benevolence 23 is installed on the solid plate 22.

Ejecting mechanism 30 comprises push rod 31, a jacking block 32 and an angle ejector rod 33 that links to each other with jacking block 32 upper ends always.Angle ejector rod 33 1 ends convex with a hook portion 331 to a side.Straight push rod 31 1 ends are fixed on the ejector retainner plate 13, and straight push rod 31 other ends can pass moving platen 12 and extend in the accepting groove 121.Jacking block 32 is contained in the accepting groove 121 and can moves up and down in accepting groove 121, angle ejector rod 33 is inserted in the inclined hole 161 slidably and stretches out in core 16, angle ejector rod 33 other ends are deep in the accepting groove 121 and by a fixed screw 40 and are fixedly linked with jacking block 32, and described through hole 122 convenient fixedly spiral shells 40 are fixed in angle ejector rod 33 on the jacking block 32 from moving platen 12 lower ends.Straight push rod 31 other ends can be resisted against jacking block 32 lower ends.

See also Fig. 1, during injection mold 1 matched moulds, hook portion 331 cooperates the die cavity (figure does not show) that forms a shaped article barb with core 16, cover half benevolence 23 end faces.The release link 24 of cover half 20 is resisted against jacking block 32 upper ends, thereby makes ejecting mechanism 30 homings.

See also Fig. 2, during injection mold 1 die sinking, straight push rod 31 in the vertical directions of ejecting mechanism 30 promote jacking block 32, jacking block 32 drives angle ejector rod 33 and moves upward, angle ejector rod 33 upwards ejects product with thimble 15, angle ejector rod 33 also moves to the inside when ejecting product, and the hook portion 331 of angle ejector rod 33 is broken away from the product barb gradually, and product can eject smoothly fully thus.

As mentioned above, the utility model injection mold 1 is provided with ejecting mechanism 30 by dynamic model 10, and then when having barb on product, uses the angle ejector rod 32 of ejecting mechanism 30 to eject simultaneously in the horizontal direction with on the vertical direction, thereby make the smooth demoulding of product, to enhance productivity.
