Abstract

The utility model discloses a core extraction mechanism of mould; a fixed mould is fixed and connected with a fixed mould core; a mobile mould is fixed and connected with a mobile mould core; a back seat of a core extraction device is arranged between the fixed mould core and the mobile mould core; a back seat of the core extraction device is connected with the core extraction head through a bolt; the core extraction head passes through the active block of the mould core and matches with the active block of the mould core with spacing between; the active block of the mould core is connected with the mobile mould through a bolt; the lift-out device next to the mobile mould is provided with the space for the installation and disassembly of the bolt. The utility model can conveniently extracts the clamped core extraction device, realize the rapid repair of moulds and ensure the continuity of the production.

Description

The core-pulling mechanism of mould
Technical field
The utility model is particularly related to a kind of core-pulling mechanism of mould.
Background technology
Core-pulling device in the mould passes the inner core-pulling mechanism that forms of core rod at present, and core-pulling device inserts in the core rod, and cooperation between the two is a matched in clearance.In process of production,, cause producing material (as aluminium liquid) and pierce in the gap, cause taking out center device, or mould produces distortion, form stuck phenomenon in causing moving with core rod is stuck because pressure or the device fit clearance of loosing core increase.Need to take apart all parts of mould after stuck, even adopt the method for machining to take out.Recovery time is long, the cost height, and workload is very big.
Summary of the invention
The purpose of this utility model is at having problems in the above-mentioned prior art, a kind of Mold Core-pulling Mechanism that provides, and it can take out the stuck center device of taking out easily, realizes quick repairing mould, guarantees the continuity of producing.
The purpose of this utility model is achieved in that fixedly connected cover half core on the cover half, fixedly connected moving-mould-core on the dynamic model, be provided with the core-pulling device back seat between cover half core and the moving-mould-core, connect the head of loosing core by screw on the core-pulling device back seat, loose core the head pass the core rod movable block and with core rod movable block matched in clearance, the core rod loose piece is connected with dynamic model by screw, the liftout attachment adjacent with dynamic model be provided be used to install, the room of knockout screw.
Owing to adopted such scheme, connect the head of loosing core by screw on the core-pulling device back seat, the head of loosing core pass the core rod movable block and with core rod movable block matched in clearance, the core rod loose piece is connected with dynamic model by screw, the liftout attachment adjacent with dynamic model be provided be used to install, the room of knockout screw.Stuck in mould the time when loosing core, only need from the room, remove screw, withdraw from base member behind the core-pulling mechanism simultaneously, can simultaneously core rod loose piece and the stuck head of loosing core be taken out, load onto spare part and can resume production.Use the core-pulling mechanism of this structure can avoid reducing the workload of repairing like this, reduce the time of recovering, make to produce to obtain fast quick-recovery in all parts that to take mould when stuck apart of loosing core taking-up of to loose core.
The utility model is simple in structure, and mounting or dismounting are convenient.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, be screwed on the cover half 1 and connect cover half core 2, be screwed on the dynamic model 10 and connect moving-mould-core 11, be provided with core-pulling device back seat 12 between cover half core 2 and the moving-mould-core 11, be screwed on the core-pulling device back seat 12 to install and loose core 3, core-pulling device back seat 12 can move up and down with respect to dynamic model 10, loose core 3 pass core rod loose piece 5 and with core rod movable block matched in clearance, its two ends participate in the moulding of foundry goods 4.Core rod loose piece 5 is connected on the dynamic model 10 by soket head cap screw 6.The liftout attachment 7 adjacent with dynamic model 10 be provided be used to install, the room 8 of knockout screw 6.The push rod 9 of this liftout attachment 7 passes dynamic model 10 and moving-mould-core 11, is used for ejecting foundry goods 4 after the die sinking.
When in foundry production, owing to reasons such as pressure or die deformations, the head of loosing core that causes core-pulling device is with stuck and can't extract out the time by the core rod loose piece, only the screw that connects the head of loosing core on the core-pulling device back seat need be unloaded, then from the liftout attachment adjacent being used to of being provided with dynamic model install, the empty place of knockout screw removes the soket head cap screw that is connected the core rod loose piece, withdraw from base member behind the core-pulling device simultaneously, just can be with core rod loose piece and stuck first the taking-up of loosing core, and reinstall ready spare part and can resume production immediately.
