Fixed handle;The horizontal part or so of limit lantern ring moving handle slides setting in limit shifting chute and passes through lower die and holds accordingly
Face;The horizontal position of lantern ring moving handle is limited in the outside of lower die;The left and right end face of lower die is located at limit lantern ring moving handle
Rear side be separately formed translation baffle;The separate one end of a pair of translation baffle is vertically provided with forward driven in translation plate;Translation
Driven in translation bolt is bolted in driving plate;The horizontal part of limit lantern ring moving handle is screwed on driven in translation bolt;It is a pair of
The close one end of driven in translation bolt is articulated on the corresponding end face of lower die.
As the preferred of above-mentioned technology, translate and graduation mark is set on the front end face of baffle.
The beneficial effects of the present invention are: the upper and lower mould separation during being opened slowly is conducive to the Forming Quality of workpiece,
And opening stroke is adjustable, facilitates the taking-up of workpiece.

Specific embodiment
As shown in Figure 1 and Figure 2, the adjustable injection mold of a kind of opening stroke, including upper mold 10, lower die 20 and die-sinking device
30;The lower part of lower die 20 forms the driver slot 200 of rectangle;The upper side wall lifting of driver slot 200 is provided with two pairs of bilateral symmetries
Guide rod 31;The upper end of guide rod 31 is fixedly connected with upper mold 10;The lower end of guide rod 31 is hinged with center connecting rod 35;It opens
Mold device 30 includes double end motor 32;Double end motor 32 is fixed at the lower wall center of the driver slot 200 and left and right sides
Driving threaded rod 33 is fixedly connected on output shaft;The other end of driving threaded rod 33 is articulated in the corresponding side wall of driver slot 200
On;Driving threaded rod 33 is bolted with mobile support base 34;Mobile support base 34 or so slides the lower wall that driver slot 200 is arranged in
On;The lower end of a pair of of center connecting rod 35 in left side is hinged on 34 rear and front end of mobile support base in left side;One centering on right side
The lower end of heart connecting rod 35 is hinged on 34 rear and front end of mobile support base on right side;It is arranged with respectively on a pair of driving threaded rod 33
The limit lantern ring 36 that can be moved left and right;Pressure sensor 361 is provided on limit lantern ring 36;At pressure sensor 361 and signal
Manage device electrical connection;Signal processor is electrically connected with double end motor 32.
As shown in Figure 1, the upper end of guide rod 31 passes through upper mold 10 from bottom to top;The top of guide rod 31 is bolted with to be divided up and down
The upper fixture nut 312 of cloth and lower fixture nut 311;Upper fixture nut 312 and lower fixture nut 311 are located at upper mold 10
The upper side and lower side;After upper mold 10 is fixedly connected with guide rod 31;The lower end surface of lower fixture nut 311 and the lower end surface of upper mold 10
Concordantly.
As shown in Figure 1, the lower wall of driver slot 200 offers the limition orientation slot 201 of two pairs of left and right settings;Mobile support
The lower end surface of seat 34 forms the mobile guide block 341 cooperated with limition orientation slot 201.
As shown in Fig. 2, forming a pair of symmetrical limit shifting chute 202 in the middle part of the lower wall of driver slot 200;It is a pair of
Separate one end of limit shifting chute 202 extends vertically through the left and right end face of lower die 20;A pair of limit lantern ring 36 or so slides setting
In limit shifting chute 202;The limit that cross section is in the L-type lain on one's side is vertically and fixedly provided on the separate end face of a pair of limit lantern ring 36
Position lantern ring moving handle;The horizontal part or so of limit lantern ring moving handle slides setting in limit shifting chute 202 and passes through
The corresponding end face of lower die 20;The horizontal position of lantern ring moving handle is limited in the outside of lower die 20;The left and right end face position of lower die 20
Translation baffle 37 has been separately formed on rear side of limit lantern ring moving handle;A pair translates the separate one end of baffle 37 vertically forward
It is provided with driven in translation plate;Driven in translation bolt 38 is bolted on driven in translation plate;Limit the horizontal part spiral shell of lantern ring moving handle
It connects on driven in translation bolt 38;The close one end of a pair of of driven in translation bolt 38 is articulated on the corresponding end face of lower die 20.
As shown in Fig. 2, graduation mark 371 is arranged on the front end face of translation baffle 37.
The die sinking working principle of injection mold:
Carry out opening stroke setting first to adjust: the driven in translation bolt 38 for rotating two sides respectively drives a pair of of limit lantern ring
36 move left and right, and are subject to graduation mark 371;Then start double end motor 32, drive a pair of symmetrical mobile support base 34
It is separate, promote four guide rods 31 are synchronous to rise by center connecting rod 35 in this way, i.e. drive upper mold 10 moves up, and supports when mobile
When seat 34 is resisted against on pressure sensor 361, pressure sensor 361 gives signal processor signal, and signal processor issues double end
Motor 32 stops, and such upper mold 10 and lower die 20 complete die sinking, and opening stroke is identical as the opening stroke set before.
