In figure for the mutual alignment relation of each component part of the utility model.
In addition, unless otherwise defined, the technology of all technical and scientific terms used herein and the art
The normally understood meaning of personnel is identical.Term used in the description is intended merely to description specific embodiment herein, without
It is to limit the utility model.Term " and or " used herein includes appointing for one or more relevant listed items
The combination of meaning.
Referring to Fig.1, Fig. 2, shows the front view and cross-sectional view of the utility model one embodiment, including runner mold insert 2,
Runner mold insert fixing piece 6, limited block 5 and regulating valve screw 4.Runner mold insert 2 is located at the side of die joint 1, sets on runner mold insert 2
There are two runners 3, central symmetry of two runners 3 about runner mold insert.The bottom wall of every runner 3 is in vertical-parting face
A through-hole is equipped on 1 direction, with respect to the central symmetry of runner mold insert 2, the diameter of the through-hole is greater than to be shunted two through-holes
The width in road 3.Runner mold insert is equipped with groove in the one side contacted with runner mold insert fixing piece 6, and above-mentioned through-hole passes through groove.This
Outside, two runners can also be not in relation to the central symmetry of runner mold insert；The quantity of runner may be three or a plurality of, also
It can be an only runner.
Runner mold insert fixing piece 6 is used for stationary flowpath mold insert 2, is connected between the two by dismountable connection type, this
Embodiment is preferably threadedly coupled.Coaxial screw thread is equipped in the position of the through-hole of corresponding runner mold insert 2 on runner mold insert fixing piece 6
Hole.Runner mold insert fixing piece 6 is additionally provided with groove on the face contacted with runner mold insert 2, the groove on this groove and runner mold insert 2
Position is corresponding, and threaded hole originates in the bottom surface of this groove, and the bottom surface of groove is rectangular.
Limited block 5 is cuboid, and the bottom of limited block 5 is located in the groove of runner mold insert fixing piece 6, opposite runner mold insert
Fixing piece will not occur relative to groove floor movement is parallel to, and the top of limited block and the groove of runner mold insert 2 are supported, limited
Limited block 5 is in the movement perpendicular to die joint direction.5 center of limited block is equipped with a through-hole, is put into groove in limited block 5
Afterwards, this through-hole and the through-hole on runner mold insert 2, the threaded hole on runner mold insert fixing piece 6 are coaxial.
Regulating valve screw 4 is hexagon socket head cap screw, including head and interconnecting piece, head and interconnecting piece are coaxially connected, head and
The position of interconnecting piece contact is root.The interconnecting piece of regulating valve screw 4 is equipped with screw thread, and the diameter on head is greater than the straight of interconnecting piece
Diameter, the diameter on head are equal to the diameter in the hole on runner mold insert 2.The length on the head of regulating valve screw is less than runner bottom to limit
The distance between at the top of the block of position, and it is greater than the depth of runner 3.
Operating method:
When production, by regulating valve screw towards the internal rotating of runner mold insert 2, until entire head is completely in runner edge
In hole on part, 7 connection of runner 3 and cast gate, colloid all pass through runner 3 and cast gate 7 at this time, into molding room 8.
If the molding product of Liang Ge molding room 8 is identical product, staff's discovery is the same as batch molding two products
Consistency is bad, then rotating regulation valve screw appropriate, changes flow of the plastics colloid by runner, then can make two moldings
Room is equally uniform into glue, guarantees the consistency of two products.
If the molding product of Liang Ge molding room is different, one of regulating valve screw 4 can be individually adjusted, is protected
It demonstrate,proves the product that its corresponding molding room molds and meets technological standards.
Alternatively, when thinking only to allow one of molding room 8 to work, the corresponding regulating valve spiral shell of adjustable another molding room
Silk 4, is aligned the end face on its head with die joint 1, runner, runner and cast gate are blocked in the head of regulating valve screw 4 completely
Isolation, then colloid will not enter another molding room 8 by corresponding runner, only one molding room 8 works at this time.
It is above a preferred embodiment, can also does and suitably be altered or modified on this basis.For example, runner mold insert with
Runner mold insert fixing piece is wholely set, without runner mold insert fixing piece；Runner mold insert can not also be adopted with runner mold insert fixing piece
It is threadedly coupled, and runner mold insert is processed into a step, be connected in the moving template of runner mold insert fixing piece and mold (in figure
It is not shown) between；The diameter of through-hole is also possible to the width less than or equal to runner on runner；On runner mold insert fixing piece
Hole can also there is no screw thread, as long as the hole on hole and limited block on runner mold insert fixing piece one of them be threaded i.e.
It can；Bottom portion of groove shape on runner mold insert fixing piece can not also be rectangular, as long as limited block can be limited not in a groove
It moves freely；Regulating valve screw is also possible to grub screw, at this point, on runner mold insert, runner mold insert fixing piece, limited block
Bore dia be equal to the diameter of regulating valve screw.
Referring to figure 3., another embodiment of the utility model is shown, the difference of the present embodiment and one embodiment exists
In the present embodiment does not use limited block, correspondingly, not having groove on runner mold insert and runner mold insert fixing piece.
Runner mold insert is equipped with through-hole, runner mold insert fixing piece corresponding position it is coaxial be provided with threaded hole, adjust
The interconnecting piece of valve screw is connect with threaded hole.The present embodiment to be generally used for die size into plastic structure smaller, do not need to limit
Block just can control the situation of the extreme position of regulating valve screw, reduce the total number of parts of mold.
It is illustrating for progress to be implemented to the preferable of the utility model, but the invention is not limited to the reality above
Example is applied, those skilled in the art can also make various equivalent variations without departing from the spirit of the present invention
Or replacement, these equivalent deformations or replacement are all included in the scope defined by the claims of the present application.
