The inverted T shaped guide pad 411 cooperated with T-type surface groove 4211 is offered, when molding, inverted T shaped guide pad 411 and T-type surface groove
4211 is chimeric, when die sinking, under the guiding of T-type surface groove 4211, core-pulling member by T-type guide pad along the first slippage slot 21 to
A side slip far from forming cavity.
Referring to figs. 2 and 3, dynamic model 2 be provided between two first slippage slots 21 two it is vertical with the first slippage slot 21 but
Disconnected second slippage slot 22, sliding is connected with slipping block 5 on the second slippage slot 22, is installed on slipping block 5 towards molding
The molding needle 51 of chamber.The connecting hole 23 being overlapped with molding 51 axis of needle is offered on dynamic model 2, connecting hole 23 is connected to forming cavity.
The end that molding needle 51 wears by connecting hole 23, and forms needle 51 is threaded through in forming cavity for formed hinge hole 93.Cover half 1
On be also provided with first guide pillar hole fixed for inclined guide pillar 6, the first guide pillar hole is to the direction inclination far from forming cavity and its direction
The opening of 1 side of cover half is located exactly at 5 top of slipping block, offers second be overlapped with the first guide post axially bored line on slipping block 5
Guide pillar hole, inclined guide pillar 6 are threaded through in the second guide pillar hole, and when die sinking, slipping block 5 can be slid along inclined guide pillar 6.
When mold clamping, melt enters forming cavity by pouring basin 11, up to 9 product of mirror holder after cooling.Then die sinking is moved
Mould 2 slides to the direction far from cover half 1.At this point, trapezoid block 421 is remain stationary with cover half 1, and Loose core block 41 and dynamic model 2 are in the same direction
Sliding makes Loose core block 41 along the first slippage slot 21 to separate when inverted T shaped guide pad 411 slides along T-type surface groove 4211
The direction of forming cavity slides, and is detached from 41 end face of Loose core block from product surface.
Meanwhile dynamic model 2 to cover half 1 far from when, inclined guide pillar 6 is installed on cover half 1, the sliding for keeping cover half 1 separate
Block 5 is oriented to the second slippage slot of lower edge 22 on the inclined-plane of inclined guide pillar 6 and slides to the direction far from forming cavity, to keep molding needle 51 de-
From forming cavity, separate molding needle 51 with forming cavity.
Meanwhile as dynamic model 2 and cover half 1 separate, distance between the two increases, and elastic component 15 is by guide post 31 along positioning
Hole is popped up to 2 direction of dynamic model, and as the reply volume of elastic component 15 increases, two are threaded through the forming blocks 3222 in first positioning hole 12
It is gradually distance from inside lens channel 911, two forming blocks 3222 being threaded through in second location hole 13 are gradually distance from outside lens channel
912.When the connecting column 321 being threaded through in first positioning hole 12 is detached from first positioning hole 12, connecting column 321 can be oppositely oriented
Column 31 rotates, and shaping column 32 gradually separates with product, similarly, when the connecting column 321 being threaded through in second location hole 13 is detached from the
When two location holes 13, connection can equally be oppositely oriented the rotation of column 31, and shaping column 32 is gradually separated with product.
At this point, several mandrils being located on dynamic model 2 can eject product, the demoulding of product can be completed.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
