The mobile phone protective cover injection mold of the utility model embodiment is described in detail with reference to the accompanying drawings.
Show referring to figs. 1 to Fig. 8, according to mobile phone protective cover injection mold provided by the embodiment of the utility model, including it is preceding
Mode 10, rear cavity 20 and Slide mechanism 30.
Specifically, front cavity 10 is equipped with glue-feeder 101.
Rear cavity 20 is equipped with four sliding blocks 201 corresponding with the four edges of mobile phone protective cover 40 respectively, four cunnings
Block 201 and the rear cavity 20, front cavity 10 limit product type chamber jointly, each sliding block 201 along close to or far from
The direction of the product type chamber is slidably.In Fig. 2 example, two sliding blocks 201 move along the longitudinal direction, and other two sliding block
201 move in left-right direction.
It is intracavitary and be formed with spatia between the product type chamber that Slide mechanism 30 is located at the product type；The line position
Slide insert 303 including three Inner slide mold insert 301, three oblique slide inserts 302 and always of mechanism 30, wherein described in three
Inner slide mold insert 301 is corresponding with the middle part on three sides of mobile phone protective cover 40 respectively, and each Inner slide mold insert 301 is inside
Side is slidably；Three oblique slide inserts and the straight slide insert 303 respectively with four corners pair of mobile phone protective cover 40
It answers, and slidably, the straight slide insert 303 is upward slidably for oblique upper inwardly for each oblique slide insert.
That is, product type chamber limit is 40 outer surface profile of mobile phone protective cover, and Slide mechanism 30 is located at product
The intracavitary restriction of type be mobile phone protective cover 40 inner surface profile, the spatia between product type chamber and Slide mechanism 30 is then
Ejection formation, when the glue-feeder 101 of front cavity 10 injects colloid, colloid, which enters to, forms mobile phone protective cover in the spatia
40, it that is to say, the ejection formation in the spatia of mobile phone protective cover 40.
And three Inner slide mold inserts 301 in Slide mechanism 30 can be moved to side, three diagonal positions can inside skew back
Top sliding, straight slide insert 303 upper below can be slided, in this way, can pass through three Inner slide mold inserts, 301, three diagonal positions
Automatic demoulding is realized in the movement of mold insert 302 and always slide insert 303.
In demoulding, firstly, two sliding blocks 201 are moved to the direction being relatively distant from left-right direction, other two sliding block
201 move to the direction being relatively distant from along the longitudinal direction, then, three Inner slide mold inserts 301 inwardly move it is bringing together, into
One step, straight slide insert 303 moves upwards again, finally, oblique upper moves three oblique slide inserts 302 inwardly, it is final real
It is now separated with mobile phone protective cover 40, completes automatic demoulding.
According to mobile phone protective cover injection mold provided by the embodiment of the utility model, three Inner slide mold inserts 301 are distinguished
It is corresponding with the middle part on three sides of mobile phone protective cover 40, and each Inner slide mold insert 301 is inwardly slidably；Three diagonal position edges
Part and straight slide insert 303 are corresponding with four corners of mobile phone protective cover 40 respectively, and on each tiltedly inside skew back of slide insert
Can slide, straight slide insert 303 upwards slidably, in this way, in demoulding, three Inner slide mold inserts 301 inwardly slidably,
Straight slide insert 303 upwards slidably, three oblique slide inserts inwardly oblique upper slidably, in this way, may be implemented to take off automatically
Mould, demoulding efficiency is high, and it is possible to avoid the problems such as bad caused by artificial strong off-square formula.
In one embodiment of the utility model, at least one slide opening H201, institute are set on each sliding block 201
It states the direction of the axis of slide opening H201 within outer to tilt upwards, is slidably installed with a guide rod 202 in each slide opening H201,
That is, guide rod 202 is located in slide opening H201, in die sinking, four sliding blocks 201 are slided along guide rod 202, and then are realized to production
Product type chamber close to or far from.
In one embodiment of the utility model, the center of rear cavity 20 is equipped with a hollow out mouth H20, three experts
Mold insert 301, the three oblique slide inserts 302 in position and the straight slide insert 303 are set in the hollow out mouth H20；Four
The sliding block 201 is arranged around the hollow out mouth H20 respectively, in this way, structure is more compact, also, utilizes each of hollow out mouth H20
Side is as limit, so that when three Inner slide mold insert 301, three oblique slide inserts 302 and the straight molding of slide insert 303 more
It is smoothly reliable.
More specifically, one end of hollow out mouth H20 is formed with the first base station 203, and first base station 203 is equipped with edge
The perforative straight hole H203 of up and down direction and the first inclined hole H206, the other end of the hollow out mouth H20 are formed with opposite second base station
204 and third base station 205, second base station 204 is equipped with the second inclined hole H204 perforative along the vertical direction, the third base
Platform 205 is equipped with third inclined hole H205 perforative along the vertical direction.
Straight mandril 306, the upper end of the straight mandril 306 and the straight slide insert 303 have been slidably installed in straight hole H203
It is connected, has been slidably installed with an angle ejector rod 305 respectively in the first inclined hole H206, the second inclined hole H204 and third inclined hole H205,
The upper end of each angle ejector rod 305 is connected with the corresponding oblique slide insert 302 respectively.
In three Inner slide mold inserts 301 one between first base station 203 and second base station 204,
Another in three Inner slide mold inserts 301 is between first base station 203 and the third base station 205, three institutes
Another in Inner slide mold insert 301 is stated between second base station 204 and the third base station 205.
In this way, straight mandril 306 can push straight slide insert 303 to move upwards when stretching out upwards along straight hole H203, and it is oblique
When the corresponding first inclined hole H206 of mandril 305, the second inclined hole H204 or third inclined hole H205 are moved obliquely upward, it can push
Oblique upper moves oblique slide insert 302 inwardly.
In one embodiment of the utility model, each Inner slide mold insert 301 has an outer inclined-plane S301, described
The direction of outer inclined-plane S301 from outside to inside tilts upwards, and the outer inclined-plane S301 is equipped in sliding slot a G301, the sliding slot G301
Slidably it is installed with oblique piece 304.In this way, Inner slide mold insert 301 can be pushed along the chute when moving upwards for oblique piece 304
G301 is moved inwardly.
It is advantageous, it is connected on a push rod for described oblique piece 304 on three Inner slide mold inserts 301, the push rod
It moves along the vertical direction.In this way, three oblique piece 304 can be pushed to move upwards when push rod moves upwards, and then drive three
A synchronization of Inner slide mold insert 301 moves inwardly.
Preferably, the width of the Inner slide mold insert 301 between the second base station 204 and the third base station 205 is less than
Spacing between the other two Inner slide mold insert 301, in this way, described between the second base station 204 and the third base station 205
The space that Inner slide mold insert 301 moves inwardly is bigger, guarantees the reliability of demoulding.
