Description
Technical field
The utility model relates to mould applications, and especially a kind of movable insert formula of injection mold takes structure out of.
Background technology
Injection mold is the important production equipment for processing plastic goods, has obtained in industries such as automobile, building, household electrical appliance, food, medicine and has generally used.The control accuracy of injection mold, service life and maintainability directly affect quality and the production efficiency of plasthetics.Need after plastic cement products is shaping through stripping process, this demoulding is normally undertaken by thimble, but for products such as mobile phone shell, because the thickness of product structure differs, and the uncertainty of thimble force, easily cause the slow even damage of product of stripping rate, thus have impact on mould and produce and carry out continuously and efficiently.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of accurate positioning, eject the movable insert formula of efficiency injection mold high, easy to use takes structure out of.
The technical solution of the utility model is: a kind of movable insert formula of injection mold takes structure out of, comprise several movable inserts be arranged in die, it is characterized in that: described movable insert is vertically arranged in die, be provided with the contract block can fitted with movable insert side in die, described movable insert top is processed with one or more formed product district.
Described movable insert is L-type or T-shaped, is provided with the rectangle contract block can fitted with movable insert side in die, and the corresponding surface in the bottom surface of movable insert and die is plane.
Described movable insert is the movable insert that can be exhausted.
Described movable insert formula ejecting mechanism also comprises the ejector retainner plate be arranged on mold base, described ejector retainner plate is provided with oblique top, with the oblique top movable contact of ejector retainner plate or be fixedly connected with bottom movable insert, under the driving of ejector retainner plate, the upward stroke on movable insert top is 1/4 ~ 3/4 of thimble stroke.
Described die is provided with the formed product district that several and movable insert are nature transition.
The beneficial effects of the utility model are: easily broken and when not allowing to arrange thimble under the position of bone when product has the dark position of bone, the demoulding, employing sort of activity mold insert ejects and jack-up stroke is 1/4 ~ 3/4 of thimble stroke, can improve and eject efficiency and make product not fragile, simultaneously compared with other homogeneous structures, sort of activity insert structure is simple, be vented, jack-up is effective.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is matched moulds, the die opening state enlarged drawing in A portion in Fig. 1.
Fig. 3 is the enlarged drawing in B portion in Fig. 2.
In figure, 1-die, 2-mold insert, 3-product.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
As shown in Figure 1, a kind of movable insert formula of injection mold takes structure out of, comprise several movable inserts 2 be arranged in die 1, it is characterized in that: described movable insert 2 is vertically arranged in die 1, top in described movable insert 2 and die 1 is processed with one or more formed product district, die 1 is provided with formed product district nature transition on movable insert 2 and quantity formed product district one to one, this structure of movable insert 2 has degassing function, can ensure that the dark position of bone part of product 3 is walked the full not starved of glue and do not burnt
;
In the present embodiment, described movable insert 2, in L-type, is provided with the rectangle contract block that can fit with movable insert 2 side and the bottom surface of plane in die 1 and movable insert 2 is plane in die 1;
In the present embodiment, described movable insert formula ejecting mechanism also comprises the ejector retainner plate be arranged on mold base, described ejector retainner plate is provided with thimble and oblique top, thimble contacts with product 3 through mold base and die 1, the bottom of movable insert 2 is with the oblique top movable contact of ejector retainner plate or be fixedly connected with, and under the driving of ejector retainner plate, the upward stroke on movable insert 2 top reaches 1/4 ~ 3/4 of thimble stroke.
During concrete enforcement, as shown in Figures 2 and 3, during matched moulds, L-type movable insert 2 is in initial position, then first realized once pushing work to product 3 under ejector retainner plate drives by ejector retainner plate thimble and L-type movable insert 2 during die sinking, when the bottom of movable insert 2 and the rectangle contract block of die 1 are fitted, the dark position of bone part (thicker region) of product 3 departs from die 1, by the ejector retainner plate thimble in die 1, secondary is realized to product 3 again and push work, now movable insert 2 is spacing by the rectangle contract block of die 1, product 3 departs from movable insert 2, thus realize complete stripping operation, protection product can not take off spends de-breaking.
In the present embodiment; or; the oblique top movable contact that described movable insert 2 is not corresponding with ejector retainner plate or be fixedly connected with; ejector retainner plate realizes once pushing work to product 3; the bonding force of product 3 drives movable insert 2 upwards movable, and the dark position of bone part (thicker region) of product 3 departs from die 1, when the bottom of movable insert 2 and the rectangle contract block of die 1 are fitted; product 3 departs from movable insert 2, thus protection product once push in work can not take off spend de-disconnected.
What describe in above-described embodiment and description just illustrates principle of the present utility model and most preferred embodiment; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.
