Description
Technical field
The utility model relates to technical field of mold, is specifically related to the pulled core structure for the production of the casting mold of dust catcher outer barrel.
Background technology
Dust catcher is small household appliances common in daily household, its outer barrel is working of plastics, conventionally all complete by plastics injection mould injection moulding, also there is larger impact to the quality of product in the efficiency that the design of mould structure directly has influence on mould core pulling simultaneously, although mould structure can complete and loose core smoothly now, but efficiency is low, poor reliability easily causes the quality problems of outer barrel.
Utility model content
The applicant improves for above-mentioned shortcoming of the prior art, and a kind of pulled core structure of dust catcher outer barrel casting mold is provided, and it is simple in structure, and the efficiency of loosing core is high, and good reliability easily ensures product quality.
The technical solution of the utility model is as follows:
A kind of pulled core structure of dust catcher outer barrel casting mold, comprise die shoe, on die shoe with lower die cavity, the both sides of the described lower die cavity slide rail that is connected, the two ends that die shoe is positioned at described lower die cavity are fixed with support, cylinder is installed on support, the push rod of cylinder is connected with right die holder with the left die holder being arranged in described lower die cavity, left die holder and right die holder are positioned at the sidewall of slide rail all with slide opening, the piece of loosing core is positioned at described slide opening and is supported on slide rail, the tilting pull bar on piece of loosing core, loose core piece and pull bar are slidably matched; Loose core piece end with T-slot, at right angle setting pumping pin in described T-slot, the piece of loosing core contacts bottom surface with L shaped step with slide rail, when matched moulds, between the sidewall of described L shaped step and slide rail, have gap; In left die holder and right die holder, along slide rail parallel direction, mould pin is installed, the end of mould pin and pumping pin contacts.
Technique effect of the present utility model:
The utility model is simple in structure, and the efficiency of loosing core is high, good reliability and there will not be quality problems in the time loosing core, and production efficiency and quality all easily ensure.
Brief description of the drawings
Fig. 1 and Fig. 2 are the structural representation of product (dust catcher outer barrel).
Fig. 3 to Fig. 5 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
See Fig. 1 to Fig. 5, the utility model comprises die shoe 2, on die shoe 2 with lower die cavity, the both sides of the described lower die cavity slide rail 9 that is connected, the two ends that die shoe 2 is positioned at described lower die cavity are fixed with support 5, cylinder 8 is installed on support 5, the push rod of cylinder 8 is connected with right die holder 3 with the left die holder 4 being arranged in described lower die cavity, start cylinder 8 can the left die holder 4 of push-and-pull and right die holder 3 in described lower die cavity, slide along slide rail 9, realize matched moulds or mold closing, the sidewall that left die holder 4 and right die holder 3 are positioned at slide rail 9 is all with slide opening, the piece 10 of loosing core is positioned at described slide opening and is supported on slide rail 9, the tilting pull bar 12 on piece 10 of loosing core, the piece 10 of loosing core is slidably matched with pull bar 12, and described pull bar 12 is connected with upper bolster (China does not draw), when described upper bolster is upwards when parting, can drive upwards translation of pull bar 12, pull bar 12 is due to oblique setting, and the piece 10 of movably loosing core applies the effect of horizontal force, and piece 10 translation on slide rail 9 can make to loose core, loose core piece 10 ends with T-slot 6, the interior at right angle setting pumping pin 11 of described T-slot 6, pumping pin 11 is identical with the piece of loosing core on two wood side-guides 9, be paired setting, in the time of matched moulds, two pumping pin 11 ends are in opposite directions nearest, can be used to generate the pin-and-hole on circle product external U-shaped connecting portion 13 or connecting portion 14, left die holder 4 is provided with mould pin 7 with right die holder 3 is interior along slide rail 9 parallel directions, the end band of mould pin 7 is fluted, the structure of described groove is corresponding with the connecting portion structure on circle product external, for generating the connecting portion on circle product external, mould pin 7 is with left die holder 4 and 3 motions of right die holder, the piece 10 of loosing core contacts bottom surface with L shaped step 15 with slide rail 9, when matched moulds, between the sidewall of described L shaped step 15 and slide rail 9, there is gap, the end of mould pin 7 and pumping pin 11 contacts, for generating the connecting portion of circle product external, and the difficult overlap that produces, in the time of parting, L shaped step 15 can carry out spacing to piece 10 horizontal movements of loosing core, can improve the translation precision of the piece 10 of loosing core,
The principle of loosing core of the present utility model is as follows:
When parting, first start upper bolster, and then drive the upwards translation of pull bar 12 of loosing core on piece 10, pull bar 12 applies the effect of horizontal force to the piece 10 of loosing core, the loose core pumping pin 11 of piece 10 ends of drive outwards moves, because the piece 10 of loosing core contacts bottom surface with L shaped step 15 with slide rail 9, improve the translation precision of the piece 10 of loosing core, restart cylinder 8, make it pull left die holder 4 and right die holder 3 from motion, extract out from the circle product external connecting portion of producing with dynamic model pin 7 simultaneously, finally realize the smooth demoulding, obtain required product.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of amendment.
