Abstract
A high precision toggle link-type mould locking device is provided, which comprises a toggle link-type driving device, a movable mould board, a pull rod, a mould and a fixed mould board. The fixed mould board locks fast a nut; the movable mould board is composed of a A-shaped stress stand V and a mould installation frame E; a ream earhole is positioned at the two feet of the A-shaped stress stand V and is connected to the toggle link-type driving device at its left; a pull rod hole D is positioned at the corner of the mould installation frame E, so that the movable mould board can be bushed to the external sphere of the pull rod and slides freely along the axial direction of the pull rod; the fixed mould board is designed with a M-shaped and a N-shaped block; the left end of the pull rod is connected to the toggle link-type driving device; the fixed mould board locks fast the nut and locks the right end of the pull rod to the corner of N-shaped block of the fixed mould block. The utility model, which is able to realize high precision mould locking, ensures little bending deformation of mould boards after mould locking and the high parallel performance in between the mould board, thus realizing the forming of high precision productions.
Description
Affiliated technical field
The utility model relates to the high accuracy toggle type mould clamping system.
Background technology
The toggle type mould clamping system of existing injection machine, clamp force often is carried near the corner at pull bar place, moving platen and solid plate all can produce the deflection that deflects in various degree, and the distortion that deflects that improves this template generally is to realize by rigidity and the machining accuracy that improves each template, but this this method is because the restriction of formwork structure, template to deflect deflection always bigger than normal, so the raising of locked mode precision is subjected to certain restriction, also influenced the precision of moulded products.
Summary of the invention
Technical problem to be solved in the utility model: a kind of high accuracy toggle type mould clamping system of injection machine is provided, and this device makes it reach high-precision requirement by the design that changes its moving platen and solid plate.
The utility model solves the technical scheme that its technical problem adopts: the high accuracy toggle type mould clamping system, it comprises the toggle rod type drive unit, moving platen, pull bar, mould, solid plate, solid plate locking nut, moving platen is designed to be made up of stressed seat of A shape and mould installation frame, the bipod place of the stressed seat of A shape is provided with hinged ear hole and can links to each other with the toggle rod type drive unit on the left side, the edge of mould installation frame is provided with tie rod hole and makes moving platen slide on the cylindrical of pull bar and can be free to slide along the axial direction of pull bar, and the left end of pull bar is connected with the toggle rod type drive unit; When the toggle rod type drive unit promotes moving platen mould between moving platen and the solid plate is pressed together, the clamp force that the toggle rod type drive unit provides makes the effect of its power transfer to the central area of moving platen by the stressed seat of A shape and the mould installation frame of moving platen, and the mould stationary plane is also in the central area of moving platen, so the double-edged stress area of moving platen is heart zone therein all, and the tie rod hole of moving platen corner is the deadweight and the guide effect of carrying moving platen, thus moving platen be subjected to deflect distortion very little; Solid plate is designed to (M), (N) two block structures, the mould installed surface is located at the left side of (M) piece, the solid plate locking nut is locked at pull bar on (N) piece corner of solid plate, be provided with groove because of between two of (M), (N) of solid plate, it deflects distortion and occurs on (N) piece solid plate when being subjected to clamp force, and (M) the mould installed surface of piece can keep smooth; So by moving platen of the present utility model, solid plate is installed the mould that clamps can keep the very high depth of parallelism, the goods precision of moulding is very high.
