Abstract
A core pulling mechanism of can cover connection holes of a plastic trash can mould comprises a mould upper compound plate and a lower compound plate. The upper compound plate is connected with a fixed mould plate, a cavity insert is installed under the fixed mould plate, a movable mould plate is installed on the lower compound plate, a core insert is installed on the movable mould plate, a mould cavity is formed between the core insert and the cavity insert, a moulded trash can is arranged in the mould cavity, and a pair of can cover connection holes are manufactured on the can body at the opening portion of the trash can. The core pulling mechanism is characterized in that a core pulling oil cylinder is respectively installed on two lateral outer walls of the movable mould plate, and a piston rod of each core pulling oil cylinder is connected with a core pulling core which penetrates through the movable mould plate to be matched with the connection holes. The core pulling mechanism utilizes the core pulling oil cylinders to drive the core pulling cores to be pulled from the connection holes, and is simple in structure, stable and reliable in oil cylinder driving action and smooth in core pulling.
Description
Technical field
The utility model relates to plastic garbage barrel die bung connecting hole core-pulling mechanism, belongs to the mould of plastics field.
Background technology
Adopt mould of plastics to produce plastic garbage bin, dustbin is divided into indoor dustbin and outdoor dustbin, and outdoor dustbin generally all is placed on the both sides of street or road, and near the people supplying throw away puts rubbish.Rubbish in the outdoor dustbin since long term exposure outside air; Easy mouldy fouling so on dustbin, install bung additional, generally is connected through axis hole between bung and the staving; Just on the staving of dustbin, be shaped on connecting hole, connecting hole connects bung through rotating shaft.Therefore, after the dustbin injection mo(u)lding, need earlier could whole dustbin to be taken out outside the mould to the connecting hole demoulding of loosing core.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming of prior art, to provide a kind of employing oil cylinder to drive fuse and loose core, and is simple in structure, stable, the reliable plastic garbage barrel die bung connecting hole core-pulling mechanism of action.
The technical scheme of the utility model plastic garbage barrel die bung connecting hole core-pulling mechanism is: comprise compound plate and following compound plate on the mould, last compound plate connects solid plate, mount type cavity insert under the solid plate down; On the following compound plate moving platen is installed; Core is installed on the moving platen is inserted, core insert and cavity block between constitute die cavity, the dustbin of moulding is arranged in the die cavity; Be shaped on a pair of bung connecting hole on the oral area staving of dustbin; It is characterized in that described moving platen both sides outer wall installs the oil cylinder of loosing core separately, the piston rod of the oil cylinder of respectively loosing core connects the fuse of loosing core, and the fuse of loosing core passes moving platen and matches with connecting hole.
The plastic garbage barrel die bung connecting hole core-pulling mechanism of the utility model, outer wall is installed the oil cylinder of loosing core separately in described moving platen both sides, and the piston rod of the oil cylinder of respectively loosing core connects the fuse of loosing core; The fuse of loosing core passes moving platen and matches with connecting hole, and after the dustbin injection mo(u)lding, the oil cylinder of loosing core drives the fuse of loosing core that is connected on the piston rod and from connecting hole, extracts out; Moving platen die sinking then; Core is inserted is separated with cavity block, again with dustbin from the core taking-up of inserting, the demoulding is accomplished.This programme drives the fuse of loosing core through the oil cylinder of loosing core and from connecting hole, looses core, and is simple in structure, and it is stable, reliable that oil cylinder drives action, looses core smoothly.
Description of drawings
Fig. 1 is the utility model plastic garbage barrel die bung connecting hole core-pulling mechanism structural representation.
The specific embodiment
The utility model relates to a kind of plastic garbage barrel die bung connecting hole core-pulling mechanism, and is as shown in Figure 1, comprises compound plate 1 and following compound plate 2 on the mould; Last compound plate connects solid plate 3 down, and mount type cavity insert 4 under the solid plate is installed moving platen 5 on the following compound plate 2; Core is installed on the moving platen is inserted 6, core insert 6 and cavity block 4 between constitute die cavity, the dustbin 7 of moulding is arranged in the die cavity; Be shaped on a pair of bung connecting hole 71 on the oral area staving of dustbin 7, it is characterized in that described moving platen 5 both sides outer walls install the oil cylinder 8 of loosing core separately, the piston rod 9 of the oil cylinder 8 of respectively loosing core connects the fuse 10 of loosing core; The fuse 10 of loosing core passes moving platen 5 and matches with connecting hole 71. and the present technique scheme is installed the oil cylinder 8 of loosing core separately at described moving platen 5 both sides outer walls, and the piston rod 9 of the oil cylinder 8 of respectively loosing core connects the fuse 10 of loosing core, and the fuse 10 of loosing core passes moving platen 5 and matches with connecting hole 71; After dustbin 7 injection mo(u)ldings; The oil cylinder 8 of loosing core drives the fuse 10 of loosing core that is connected on the piston rod 9 and from connecting hole 71, extracts out, and moving platen 5 die sinkings are then inserted core and 6 separated with cavity block 4; Dustbin 7 is inserted from core again and 6 taken out, the demoulding is accomplished.This programme drives the fuse of loosing core through the oil cylinder of loosing core and from connecting hole, looses core, and is simple in structure, and it is stable, reliable that oil cylinder drives action, looses core smoothly.
