From the point of view of the operating condition penetrated, it is most critical that high pressure drives stroke lever 240 to move ahead with high flow, and this axial gap S2 is not
Technological parameter can be impacted.In one embodiment of the invention, axial gap S2 is 0.02-0.3 millimeters, preferably
0.05-0.1 millimeters.If the S2 is too small, less than the bending degree of the injection connecting plate 230, then the interconnecting piece of the trip bar 240
246 still can afford radial load.And S2 is excessive, will cause the ring 280 and the trip bar 240 interconnecting piece 246 it
Between spacing it is excessive, influence the trip bar 240 along axial and move spacing accuracy control, and then influence die casting quality.

274.Between the transverse plane 2462 of 240 interconnecting piece 246 of the trip bar and the long groove face of the oval hole slot 274 of boring cover 270, there are slots
Gap S3.This, which results in stroke lever 240, can only atomic small rotation.In a preferred embodiment of the invention, between the slot
Gap S3 is 0.1-0.15 millimeters.In engineering, the permission deflection angle of position detecting element is ± 3 °.In design of the invention,
Under actual condition, the deflection angle actually caused only has ± 1.2 °, and therefore, this atomic small rotating range is in position detection
Within the detection range of element, position detection will not be impacted.Meanwhile this slot gap S3 also ensures the trip bar
240 floating effect, so that the trip bar 240 not will receive the influence and limitation of boring cover 270.
In conclusion radial unilateral gap S1, ring between 240 necking part 244 of above-mentioned ring 280 and the trip bar
The transverse plane 2462 of 240 interconnecting piece 246 of axial gap S2 and the trip bar between 280 and 240 interconnecting piece 246 of the trip bar
With the slot gap S3 of the oval hole slot 274 of boring cover 270 so that the end of the trip bar 240 and the ring 280 and the boring cover
Between 270 can floating connection so that between the trip bar 240 and the injection connecting plate 230 use floating connection mode.
Above structure can guarantee that the trip bar 240 keeps straight when the injection connecting plate 230 is hit power bending deformation
Linear state, and can guarantee that the trip bar 240 is restricted in a rotational direction, can only rotate small angle, and small rotation
The range turned will not influence equipment normal operation within the detection range of position detecting element.As a result, firstly, making the row
Journey bar 240 keeps linear state, tired because periodically distorting will not even be broken.Secondly, the trip bar 240 keeps linear
State, so that guide copper sleeve 265 will not be worn because of unbalance loading.Finally, the injection connecting plate 230 is both sides symmetry arrangement, bilateral separate
The floating type position detection attachment device 202 is not set, so that the periodical degreeof tortuosity of injection connecting plate 230 reduces, fracture
Probability reduces.
It by above scheme, solves the problems, such as the bending deformation of shot piston, stroke lever and injection connecting plate, improves anti-
