Description of drawings
In the accompanying drawing:
Fig. 1 illustrates first embodiment (looking from Fig. 2 left side) with side view,
Corresponding views on Fig. 2 illustrates vertically,
Fig. 3 to 5 illustrates second embodiment with the vertical view and the rearview (Fig. 5) of open mode (Fig. 3), closure state (Fig. 4),
Fig. 6 illustrates the 3rd embodiment with vertical view.
The specific embodiment
Closed side at the die casting equipment shown in Fig. 1 and 2 has the fastening base plate 1 of mould of a fixed-site and the fastening base plate 2 of mould of an activity, fixed mould halfbody 3 and 4 thereon.For the movable fastening base plate 2 of mould being moved between closing position and open position and using single-acting working cylinder 5 and 6.Characteristics of shown device are that it only has two poles 7 and 8.Mould by single-acting working cylinder 5 and 6 closed and make nut 11 and 12 be locked on pole 7 and 8 after, be used to make the closing force of mold half 3 and 4 mould assemblys via these pole applying by build-up pressure in hydraulic pressure unit 9 and 10.
Because have only two bights to load with closing force in four bights of the fastening base plate 1 of mould and 2 by pole 7 and 8, thus stipulate in the embodiment shown, with the zone line of closing force from the fastening base plate of pole guiding mould.For this reason, at the rear side of the fastening base plate 1,2 of mould top pressing board 13,14 is set, they import in two fastening base plates of mould closing force and the rotation of die casting machine longitudinal axis by means of roof pressure ring 15,16 symmetrically.
In the embodiment according to Fig. 3 to 5, the supporter of bending resistance is configured to the roof pressure framework, it with the closed force transfer of asymmetric importing to the dorsal part of the fastening base plate of mould.This roof pressure framework has with the fastening base plate 2 essentially identical appearance profiles of mould and in the bight of not passed by pole 7,8 18,19 and is connected with the fastening base plate 2 of mould.Therefore this roof pressure framework 17 also bearing make that closing force imports to the fastening base plate 2 of mould those not by the function in the bight 18,19 of pole 7,8 guiding.This point can be guaranteed thus, promptly, make in abutting connection with framework 17 surfaces of the rear surface of the fastening base plate 2 of mould and vacate size " x " at the pole tapping, thereby, under indeformable state, between framework 17 and the fastening base plate 2 of mould, obtain a gap (x), it towards the fastening base plate of mould not by pole 7, the direction in the bight 18,19 of 8 guidings is more and more littler.
In the physical dimension of this such design gaps (x) and framework, make and set down a uniform crooked curve that extends on fastening of Die and mould plate in required closing force (especially maximum close power).When the each point of same flexure degree the time, then guarantee to realize this point about base plate center symmetry (being sub-circular).
At mould closed and set up closing force in, the size of vacating " x " equalization and equalization frame is leaned on whole four bights of the fastening base plate dorsal part of mould.Can realize similar base plate flexural property thus as four pole die casting machines.
But because the geometry of equalization frame is immutable, best bending distribution only obtains at the operating point (design closing force) of unique the best.All other operating point all departs from this best point more or less.
The pressure compensation mechanism of a hydraulic pressure by as shown in Figure 6 then can overcome this defective.Constructed closed cell is equipped with the curvature correction of a hydraulic pressure, and is in addition identical with said structure.At embodiment this illustrate, wherein, curvature correction is arranged on the movable fastening base plate.
