Secondary postpones the MULTIPLE COMPOSITE structure of loosing core
Technical field
The utility model relates to a kind of injection mold, particularly relates to a kind of secondary and postpones the MULTIPLE COMPOSITE structure of loosing core.
Background technology
Present injecting products structural design becomes increasingly complex, the hole or the groove that in product, have different directions, existing product must need two or more directions to loose core in same slide block could the demoulding, just can not draw bad product while the product needed that has divides two or three orders to loose core.Because the mould size is restricted, this just requires to optimize structure, and a plurality of loosing core combined on a slide block, comes a plurality of loosing core on the same slide block of balance with various schemes.
The utility model content
The secondary that the purpose of this utility model is to provide a kind of compact conformation, the action of loosing core is reliable and stable postpones the MULTIPLE COMPOSITE structure of loosing core.
For achieving the above object, technical solution of the present utility model is:
The utility model is that a kind of secondary postpones the MULTIPLE COMPOSITE structure of loosing core, and it mainly turns to the slide block of loosing core, second to turn to the slide block of loosing core to form by big slide block, Angle Pin, first; Guide pillar hole on the described big slide block slidably is socketed on the Angle Pin and between guide pillar hole on the big slide block and the Angle Pin has one section empty avoiding gap; Described first turns to the T shape piece of slide block one end of loosing core to slip in the T-slot of a side of big slide block and turns between the T-slot of the T shape piece of the slide block of loosing core and slide block greatly first and have one section empty avoiding gap; Described second turns to the slide block of loosing core slidably to be nested with first turns in the slide block of loosing core.
After adopting such scheme, because the utility model will be equipped with big slide block, first that three kinds of different qualities loose core and turn to the slide block and second of loosing core to turn to loose core slide block and they are combined on the same group of slide block, utilize first to turn to the slide block and second of loosing core to turn to delay and Design of Steering Mechanism on the slide block of loosing core, when die sinking, loose core in proper order, avoided drawing bad product.Make the utlity model has compact conformation, the reliable and stable advantage of action of loosing core.
Loose core as not adopting the utility model to turn to, then because the angle of loosing core is big, Angle Pin is stressed easily broken greatly, and die size also can be bigger, has then overcome these shortcomings with turning to.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is an axonometric drawing of the present utility model;
Fig. 2 is the axonometric drawing of the utility model broken section;
Fig. 3 is the axonometric drawing that the utility model first turns to the slide block of loosing core.
The specific embodiment
As Fig. 1, Fig. 2 the utility model is that a kind of secondary postpones the MULTIPLE COMPOSITE structure of loosing core, and it mainly turns to the slide block 3 of loosing core, second to turn to the slide block 4 of loosing core to form by big slide block 1, Angle Pin 2, first.
Guide pillar hole 11 on the described big slide block 1 slidably is socketed on the Angle Pin 2 and between guide pillar hole 11 on the big slide block 1 and the Angle Pin 2 has one section empty avoiding gap L 1, and this structure has constituted second delay device.
Described first turns to the T shape piece 31 of slide block 3 one ends of loosing core to slip in the T-slot 12 of a side of big slide block 1 and turns to the T shape piece 31 of the slide block 3 of loosing core and have one section empty avoiding gap L 2(as shown in Figure 3 between the T-slot 12 of slide block 1 greatly first), this structure has constituted first delay device; Described second turns to the slide block 4 of loosing core slidably to be nested with first turns in the slide block 3 of loosing core (as shown in Figure 2).
Operation principle of the present utility model:
During die sinking, utilize first delay device to make first to turn to the slide block 3 of loosing core to throw off 3mm, make first to turn to the slide block 3 of loosing core, second to turn to loose core slide block 4 to throw off 16mm again, long at last directly loosing core taken off 51.5mm, finishes the demoulding.
Emphasis of the present utility model just is: be provided with two delay devices.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
