In a further embodiment, the main body fixed block is fixed on bottom plate by positioning pin and fixed screw.
The utility model has the beneficial effects that a kind of this plastic mould mechanical lock mechanism of the utility model, breaks through tradition
Mold self-locking structure is unstable, produces a kind of process improvement device of the reduction as far as possible such as dead time or adjustment time.It can show
Land consecutive production, set safety guarantee time, mechanical performance is more stable, and production quantity is more, the manufacture of unit product
Cost is lower.It overcomes injection molding machine midway to stop, self-locking dynamics is poor, causes the offer safety guarantee of burn failure, so may be used
Save the production time of injection mold.Installation speed is fast, by 30 degree of inclined-planes of preceding lock tongue and sliding 30 degree of contact of incline plane of taper pin,
Allow sliding taper pin to move slide backward by the pulling force of upper mounted plate, compressed spring is in compressive state, when coasting distance is more than A after
Lock tongue is detached from, so that it may which normal production, production and installation are simple.
