Description
Technical field
The utility model relates to thermal forming devices, and in particular to the hot forming tool that one kind can be molded accurately.
Background technique
It is existing a kind of for making the hot forming tool of plastic containers (such as plastic cup, plastic casing, plastic tub), it can
Complete molding, shear action.This hot forming tool includes upper die and lower die；Upper mold include cope plate, upper cut-off-die mounting plate and
Multiple upper cut-off-dies, upper cut-off-die mounting plate are mounted on cope plate, and upper cut-off-die mounting plate is equipped with multiple upper cut-off-die cavities, upper cut-off-die
And one-to-one correspondence identical as upper cut-off-die cavity quantity, upper cut-off-die are set in upper cut-off-die cavity, and upper cut-off-die has a cavity；Lower die packet
Lower template, lower mold body, lower cut-off-die mounting plate, knock-pin mounting plate, multiple lower cut-off-dies, multiple shaping moulds and multiple knock-pins are included,
Lower mold body is mounted in lower template and is in above lower template, and lower cut-off-die mounting plate is mounted in lower mold body and is in lower mold body
Side, lower cut-off-die is identical with upper cut-off-die quantity and corresponds that (inner edge of usually upper cut-off-die lower end is upper shearing knife edge, on lower cut-off-die
The outer rim at end is lower shearing knife edge, and lower shearing knife edge and upper shearing knife edge match), lower cut-off-die mounting plate be equipped with it is multiple under cut
Mould cavity, lower cut-off-die is identical as lower cut-off-die cavity quantity and corresponds, and shaping mould is identical as lower cut-off-die quantity and corresponds,
Knock-pin is identical as shaping mould quantity and corresponds, and lower cut-off-die is set in lower cut-off-die cavity, and shaping mould includes side mode and activity
Bed die, side mode are mounted on the inside in lower mold body and being in corresponding lower cut-off-die, the upper end of movable die block and corresponding knock-pin
Connection, knock-pin mounting plate are set to below lower template, and the lower end of each knock-pin extend out to below lower template and connects knock-pin
Mounting plate.Upper mold also typically includes multiple stretching heads, multiple stretch rods, stretch rod mounting plate and stretch rod mounting plate elevating control
Mechanism, stretching head is identical as upper cut-off-die quantity and corresponds, and stretch rod is identical as stretching head quantity and corresponds, stretching head
In the cavity of upper cut-off-die, stretch rod lower end connects stretching head, and each stretch rod upper end is all connected with stretch rod mounting plate, stretch rod
