Detailed description of the invention
Referring to figs. 1 through Fig. 5, the constitutionally stable core-pulling die embodiment of the utility model is described further.
A kind of constitutionally stable core-pulling die, comprise moving platen 1, described moving platen 1 is provided with die cavity 2, described die cavity 2 inwall is convexly equipped with forming blocks, described forming blocks comprises the shaping projection 3 being arranged on die cavity 2 bottom surface and the special-shaped forming blocks 4 being arranged on die cavity 2 sidewall, chute 7 of loosing core is formed between described special-shaped forming blocks 4 and shaping projection 3, be provided with the core-pulling mechanism 5 for facilitating product to depart from die cavity 2 when die sinking between described shaping projection 3 and special-shaped forming blocks 4, described core-pulling mechanism 5 is along chute 7 side walls of loosing core.When product needed carries out injection moulding production, core-pulling mechanism 5 on this mould will shrink back in moving platen 1 along the sidewall stability and safety of chute 7 of loosing core fast, make core-pulling mechanism 5, shaping projection 3 and special-shaped forming blocks 4 can the working in coordination of tight joint close, form complete mold cores, complete the injection moulding work of mould; After completing injection moulding, its core-pulling mechanism 5 just can, by by Roof Control, make core-pulling mechanism 5 can eject along chute 7 sidewall phase front of loosing core, and facilitates whole product to depart from cover half.Core-pulling mechanism 5 movable in this mould can stablize the slip of installation at mould inside, and all parts is connected firmly, and makes this die life higher.
Described core-pulling mechanism 5 comprises core-pulling slide block 51 and push rod 52 of loosing core; Described die cavity 2 bottom surface is provided with slip through hole 21, described in push rod 52 one end of loosing core run through slip through hole 21 and be arranged in die cavity 2, described core-pulling slide block 51 is fixedly connected with push rod 52 of loosing core in die cavity 2; Described push rod 52 of loosing core slides and promotes core-pulling slide block 51 in slip through hole 21.Described shaping projection 3 is provided with angular guide surfaces 31 towards the side of core-pulling mechanism 5, and described angular guide surfaces 31 is inconsistent with push rod 52 side of loosing core.The plane at described angular guide surfaces 31 place is α, and the side of described moving platen 1 is β, and described α and β intersects, and crossing angle is acute angle.This cover half is in the production and application process of reality, after mould matched moulds, the power-equipment that push rod 52 of loosing core on its core-pulling mechanism 5 can be arranged on other peripheral hardwares such as cylinder, oil cylinder on cover half controls, thus core-pulling slide block 51 can be made to be contracted between shaping projection 3 and the inwall of die cavity 2 timely, can match with the core of dynamic model and form injection moulding cavity, and form chamfering, crotch or the molding space of other special-shaped mechanisms with the special-shaped forming blocks 4 be arranged on die cavity 2 sidewall, never complete injection moulding work.After mold injection completes and the flow processs such as pressurize are complete, dynamic model will to the Slideslip away from cover half, carry out die sinking, and complete the blanking work of product, in the process of die sinking, its push rod 52 of loosing core that controls by top board will along angular guide surfaces 31 to core-pulling slide block 51 direction jack-up, promote core-pulling slide block 51 away from special-shaped forming blocks 4, moulding is easily pushed away moving platen 1 fast, facilitates die sinking and the blanking work of mould, greatly high operating efficiency.
Described core-pulling slide block 51 is provided with T-shaped link slot 511 with the junction of push rod 52 of loosing core; Described push rod 52 end of loosing core is provided with the T-shaped contiguous block 521 corresponding with T-shaped link slot 511.
Be provided with connecting groove 512 in described T-shaped link slot 511, described T-shaped contiguous block 521 end is provided with the connection fixture block 522 corresponding with connecting groove 512.In its core-pulling mechanism 5, topmost two structure core-pulling slide blocks 51 and push rod 52 of loosing core are exactly the effect by T-shaped link slot 511 and T-shaped contiguous block 521, can safety and stability core-pulling slide block 51 and push rod 52 of loosing core be connected and fixed, and be also provided with for installing the connecting groove 512 connecting fixture block 522 in T link slot, after finally core-pulling slide block 51 and push rod 52 of loosing core being fixed by screw 6 again, core-pulling slide block 51 is just allowed to fix at push rod 52 end of loosing core, there is structure simple, the features such as bonding strength is high, easy to connect.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
