Description
Technical field
The utility model relates in injection mold field, more particularly, to a kind of mould structure of automobile door plate.
Background technique
Injection mold divides into two kinds of thermosetting plastic mold, thermoplastic plastic's mold according to shaping characteristic；According to moulding process
It divides into and passes mold, blow molding die, draw mould, thermoforming mould, hot-die (compression mould), injection mold etc., wherein hot-die is with flash
Mode can be divided into excessive formula, semi-positive, three kinds of formula of not overflowing again, and injection mold can be divided into cold flowing mould channel, hot runner mould with running gate system again
Two kinds；It is mobile, two kinds fixed can be divided by handling mode.
Injection mold is demoulded by the way of Double-ejection, can shorten the total length of tiny thimble, guarantees thimble
Service life, while also can be reduced injection defect.
Grant number is the Chinese utility model patent number of CN201620123972.4, discloses the sound equipment of automobile door plate mold
Support block and ejector retainner plate are arranged on lower compound plate for mesh secondary ejecting mechanism, including lower compound plate, are arranged thimble on ejector retainner plate, on support block
Setting type core has automobile door plate on type core, sound equipment hole is provided on automobile door plate, fixed plate is arranged in the lower compound plate, fixed
Push plate is set on plate, push rod is set in push plate, push plate upper end is in contact with ejector retainner plate lower end, and bullet is arranged between push plate and fixed plate
Spring is provided with mounting groove under type core, is arranged secondary upper plate, secondary lower roof plate and baffle in mounting groove, on secondary upper and lower top plate
Secondary thimble is set, and the automobile door plate between secondary thimble pass-through core and each sound equipment hole is in contact, and baffle is through fastener and type
Core is mutually fixed, and perforation is provided in baffle, and push rod passes through perforation and is in contact with secondary lower roof plate.Push rod is driven to transport upwards by push plate
Dynamic, push plate is then jacked up by spring upwards, the push plate not only resistance by multiple push rods, but also by the elastic force of spring, because spring is not
To act directly on push rod bottom, due to push plate discontinuity cause to move upwards in not necessarily in horizontality, be easy
There is tilt phenomenon, final push rod is not to synchronize to move upwards, and influences mold releasability；Secondary thimble insertion moulding is for forming
The sound equipment hole of moulding, secondary thimble itself is more elongated, is but jacked up upwards by secondary lower roof plate during demoulding, therefore transports
It is easily deformed in dynamic, influences secondary thimble service life and moulding quality.
