Description
Technical field
The utility model relates to die casting technical field, particularly relates to the front mould tunnel-type slider locking auxiliary body for die casting.
Background technology
Die casting is a large class in mould, and it is a kind of method of casting liquid forging, a kind of technique completed on special die casting die forging machine.Its basic craft course is: the first low speed of molten metal or high-speed casting fill in the die cavity of type progressive die tool, mould has movable cavity surface, it, along with the cooling procedure pressurization forging of molten metal, had both been eliminated the shrinkage porosity defect of contraction cavity of blank, and had also made the interior tissue of blank reach the Broken Crystal of forging state.Along with developing rapidly of China's automobile and motorcycle industry, Die Casting Industry has welcome the new period of development, also has higher requirement to the comprehensive mechanical property, life-span etc. of die casting meanwhile.
The mould structure being directed to portioned product need do front mould tunnel slide block, the die sinking space of die casting machine coordinates this mould to again limit its mold height, be unlikely to retreat because of counter-pressure to make slide block and need design wedge block to offset counter-pressure and then locking sliding block, this kind of tunnel-type slider is locked as design wedge block needs mould to be that namely three plate structures increase by a template again in front mould template, and this exactly die casting machine die sinking space limit; The die sinking space of die casting machine is satisfied with mold height, uses three template dies to reach conventional wedge block to carry out locking sliding block no doubt passable, but this kind of unfavorable conditions such as structure mold cost of manufacture is relatively high, structure relative complex, maintenance difficult, opening period are long.
Summary of the invention
The purpose of this utility model is to provide a kind of front mould tunnel-type slider to lock auxiliary body for the deficiencies in the prior art, this structure had both relieved the restrictive condition because of die casting machine die sinking space, relieve again the conventional wedge block of design and use three template dies and the unfavorable conditions that brings out, the effect of locking can be reached again simultaneously.
For achieving the above object, the utility model adopts following technical scheme.
Front mould tunnel-type slider locking auxiliary body, it comprises oil cylinder, press strip, take-up housing, slider head and centering block; One end of described take-up housing offers groove, the both sides of take-up housing offer the square through hole of communication groove, the drag link end of described oil cylinder snaps in described groove, the front and back width of groove is greater than the front and back thickness of drag link end, described centering block is rotated by turning cylinder and is installed in square through hole, centering block is provided with snap fit end, and snap fit end pivot pin is provided with the axis of rolling; Described take-up housing other end connection sliding block head, described press strip is installed with in take-up housing both sides, and press strip offers the hook groove mated with snap fit end.
The utility model beneficial effect is: a kind of front mould tunnel-type slider locking auxiliary body described in the utility model, this structure had both relieved the restrictive condition because of die casting machine die sinking space, relieve again the conventional wedge block of design and use three template dies and the unfavorable conditions that brings out, the effect of locking can be reached again simultaneously.
Accompanying drawing explanation
Fig. 1 is decomposition texture schematic diagram of the present utility model.
State diagram when Fig. 2 is matched moulds of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As depicted in figs. 1 and 2, front mould tunnel-type slider locking auxiliary body described in the utility model, it comprises oil cylinder 4, press strip 5, take-up housing 6, slider head 8 and centering block 9; One end of described take-up housing 6 offers groove 60, the both sides of take-up housing 6 offer the square through hole 61 of communication groove 60, the drag link end of described oil cylinder 4 snaps in described groove 60, the front and back width of groove 60 is greater than the front and back thickness of drag link end, described centering block 9 is rotated by turning cylinder 7 and is installed in square through hole 61, centering block 9 is provided with snap fit end, and snap fit end pivot pin 11 is provided with the axis of rolling 10; Described take-up housing 6 other end connection sliding block head 8, described press strip 5 is installed with in take-up housing 6 both sides, and press strip 5 offers the hook groove 50 mated with snap fit end.
Front cavity 2 and rear cavity 1 matched moulds, then oil cylinder 4 does motive force, promote centering block 9 moving axis 7 that rotates to rotate, promote take-up housing 6 simultaneously and slider head 8 is advanced cause slider head 8 to put in place, now the snap fit end of centering block 9 and the axis of rolling 10 have rotated and have hooked in the hook groove 50 of press strip 5.When counter-pressure when filling is delivered to take-up housing 6, the drag link end of centering block 9, securing press strip 5 and the oil cylinder 4 that do not do extraction action forms bar pole effect through turning cylinder 7, and then offsets part counter-pressure.During die sinking, oil cylinder 4 does twitch force, drives take-up housing 6 and slider head 8 to complete action of loosing core, and then completes whole die sinking action opening front mould.This structure had both relieved the restrictive condition because of die casting machine die sinking space, relieved again the conventional wedge block of design and used three template dies and the unfavorable conditions that brings out, can reach again the effect of locking simultaneously.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in the utility model patent claim change or modify, and are included in the utility model patent claim.
