Brief description of the drawings
Fig. 1 and Fig. 2 are the structural representation of product (dust catcher outer barrel).
Fig. 3 to Fig. 8 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
See Fig. 1 to Fig. 5, the present invention includes 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,
As shown in Figure 6 to 8, in core rod groove on described lower die cavity, core rod 24 is housed, the upper circumference in core rod 24 of described lower die cavity is provided with block 29, and block 29 can play reinforcement effect to core rod 24, prevents the unstable impact that product quality is brought due to core rod 24 positions, die shoe 2 is fixed on two blocks of side plates 23, side plate 23 symmetries are fixed on base plate 26, on base plate 26, between biside plate 23, be equipped with portable plate 27, apply thrust upwards from portable plate 27 bottoms, can make portable plate 27 move upward, on portable plate 27, be provided with caulking groove, guide pad 28 is housed in described caulking groove, one end of push rod 25 coordinates with the chute on guide pad 28, described chute can increase the flexibility of push rod 25, prevent stuck, the other end of push rod 25 stretches in core rod 24 and is slidably matched with core rod 24, being applied to upward force, portable plate 27 does the used time, can promote push rod 25 moves up, stretch into one end of core rod 24 and can stretch out core rod 24, the product of castable (dust catcher outer barrel) is ejected to core rod 24, handled easily workman takes out, improve production efficiency, core rod 24 is due to the reinforcement effect of block 29, effectively prevent the impact on core rod 24 steadiness when push rod 25 moves upward, product quality is also guaranteed
The principle of loosing core of the present invention 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, apply thrust upwards from portable plate 27 bottoms, can make portable plate 27 move upward, can promote push rod 25 moves up, stretch into one end of core rod 24 and can stretch out core rod 24, the product of castable (dust catcher outer barrel) is ejected to core rod 24, handled easily workman takes out, improve production efficiency.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of amendment.
