Abstract
The utility model discloses a kind of secondary ejecting mechanism of injection mold, including solid plate, moving platen, moving clamping plate, fixed block, two pieces of centering blocks, thimble, ejector retainner plate, extension springs；Described fixed block activity is nested with moving platen, the inclined-plane that fixed block bottom has two relatively and set, the lower end of two pieces of centering blocks is respectively hinged on ejector retainner plate, the upper surface of two pieces of centering blocks acts against on fixed block and is connected with extension spring between two pieces of centering blocks, the inclined thrust surface of centering block can lean on the sloped roof of fixed block bottom, and make it that two pieces of centering blocks are swung out around its pin joint, depart from fixed block；The lower end of described thimble is fixed on ejector retainner plate, and die cavity is stretched into the upper end of thimble.When being molded due to the utility model, realized by two pieces of centering block ejection fixed blocks and ejected for the first time, reduce part enclasping force, efficiently solve because once ejecting, enclasping force is excessive, makes that product top is white, capping, and the Double-ejection of product is realized by thimble, there is the advantages of having stable behavior is reliable.
Description
Technical field
A kind of injection mold is the utility model is related to, more particularly to a kind of secondary ejecting mechanism of injection mold.
Background technology
Plastics injection mould is the instrument for producing plastic products, using very extensive.In plastic products injection molding, it is
Meeting the needs of moulding process needs multiple ejecting product, to prevent the damage of the product caused by product enclasping force is excessive.
The content of the invention
The purpose of this utility model is the secondary ejecting mechanism for providing a kind of reliable injection mold of having stable behavior.
To achieve the above object, technical solution of the present utility model is：
The utility model is a kind of secondary ejecting mechanism of injection mold, including solid plate, moving platen, moving clamping plate,
One fixed block, the second fixed block, two pieces of centering blocks, thimble, ejector retainner plate, extension springs；Described solid plate is relative with moving platen and sets,
Die cavity is provided between solid plate and moving platen, fixed block activity is nested with moving platen, fixed block bottom have two it is relative and
If inclined-plane, the lower end of two pieces of centering blocks is respectively hinged on ejector retainner plate, and the upper surface of two pieces of centering blocks acts against the bottom of fixed block
And extension spring is connected between two pieces of centering blocks, the inside middle portion of centering block is provided with inclined thrust surface, the mistake that the inclined thrust surface moves up in centering block
The sloped roof that Cheng Zhongke is relative with fixed block bottom and sets is leaned on, and make it that two pieces of centering blocks are swung out around its pin joint, is departed from
Fixed block；The lower end of described thimble is fixed on ejector retainner plate, and die cavity is stretched into the upper end of thimble.
The lower end of two pieces of described centering blocks is hinged on ejector retainner plate by rotating shaft screw respectively.
After such scheme, because the utility model includes solid plate, moving platen, moving clamping plate, fixed block, two pieces of pendulum
Block, thimble, ejector retainner plate, extension spring, during die sinking, pass through two pieces of centering block ejection fixed blocks and realize and eject for the first time, reduce part and hold tightly
Power, efficiently solve because once ejecting, enclasping force is excessive, makes that product top is white, capping, and realizes the secondary of product by thimble
Ejection, there is the advantages of having stable behavior is reliable.
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is the state diagram of the utility model matched moulds；
Fig. 2 is the side view of the utility model matched moulds；
Fig. 3 is the state diagram of the utility model die sinking process；
Fig. 4 is the state diagram of the utility model die sinking.
Embodiment
As shown in Figure 1 and Figure 2, the utility model is a kind of secondary ejecting mechanism of injection mold, including solid plate 1, dynamic model
Plate（Push pedal）2nd, the first fixed block 3,4, two pieces of centering blocks 5 of the second fixed block, thimble 6, ejector retainner plate 7, extension spring 8, rotating shaft screw 9, dynamic
Die-cushion plate 10.
Described solid plate 1 and moving platen 2 are relative and set, and moving platen 2 is superimposed on dynamic model backing plate 10, solid plate 1 with
Die cavity is provided between moving platen 2.The first described fixed block 3 is fixedly mounted on moving platen 2, and the second fixed block 4 is arranged on dynamic
On die-cushion plate 10 and the first fixed block leans, the inclined-plane 41 that the bottom of the second fixed block 4 has two relatively and set, two pieces of centering blocks 5
Lower end be hinged on respectively by rotating shaft screw on ejector retainner plate 7, the upper surface of two pieces of centering blocks 5 acts against the bottom of the second fixed block 4
Be connected with extension spring 8 between portion and two pieces of centering blocks 5, the inside middle portion of centering block 5 is provided with inclined thrust surface 51, the inclined thrust surface 51 centering block 5 to
During upper movement can inclined-plane 41 relative with the bottom of the second fixed block 4 and setting lean, and cause two pieces of centering blocks 5 around its hinge
Contact is swung out, and departs from the second fixed block 4；The lower end of described thimble 6 is fixed on ejector retainner plate 7, and the upper end of thimble 6 is stretched into
Die cavity.
Operation principle of the present utility model：
As shown in Figure 3, Figure 4, during die sinking, centering block 5 and thimble 6 are driven with the motion of ejector retainner plate 7.In the process of motion
In, screw 9 does small range circular motion to centering block 5 around the shaft, promotes the second fixed block 4, drives moving platen（Push pedal）2 and push pedal edge
Part moves, and under the collective effect of thimble 6, realizes and ejects for the first time, reduce part enclasping force.The is will be disengaged from centering block 5
During one fixed block 3, the second fixed block 4 and moving platen（Push pedal）2 contacts, control the movement locus of its Double-ejection.Ejector retainner plate 7 is not
Disconnected promotion, thimble 6 realize follow-up Double-ejection.After product ejects completely, centering block 5 is completed in the presence of extension spring 8
Reset.
It is described above, only the utility model preferred embodiment, therefore the utility model implementation can not be limited with this
Scope, i.e., the equivalent changes and modifications made according to present utility model application the scope of the claims and description, it all should still belong to this reality
In the range of being covered with new patent.
