1. Selection
Push Locks are used to prevent a second parting plane (S2) opening (T2)
prematurely, e.g. in the case of 3-plate moulds in conjunction with slides
and /or core pullers.
When combined with the Z4 range of latch locks they can:
a) Open the mould
The main parting plane is to be opened first, the stripper plate having to
remain in the starting position (e.g. when using slides and/or core pullers)
until the main parting plane has opened completely through the distance „S1“
(cf. figure 1).
b) Close the mould
The closure sequence takes place as for the stripper movement in reverse
order, i.e. the stripper plate (H1V) is moved backwards by the pulled stroke
before the main parting plane is closed.
Fitting and mounting instructions
1. General
All push locks must be mounted square, parallel and symmetrical to the
mould guide. Secure all screws with spring washers or STRACK NORM
adhesive Z9092 (fig. 2).
All areas of the control plate and control bar that are exposed to wear are
case hardened to 58 HRC. The surface hardness is about 33 HRC on the bol-
ting surfaces of the Z6 latch lock, so that the mounting holes can be drilled.
2. Preparatory work
Match the length of the control plate (21), control bar (31) and spacer (102) in
accordance with the mould design and shorten if necessary. If the abovementioned
components are to be shortened, the hardened layer on the side faces must first be
ground down (see figure 3).
Drill mounting holes in control plate (21), steady (4), control bar (31) and spacer
(102).
Drill mounting holes for control plate (21), steady (4), control bar (31) and spacer
(102) in the mould plate. The parallel dowel holes for the latch housing (11) must
be made in the mould plate at the same time (see figures 4 and 5).
