Description
Technical field
The utility model relates to a kind of mould structure technical field more particularly to a kind of throttle-valve structures for mold.
Background technique
In injection molding production, in order to improve the production efficiency, injection mold can be usually arranged to the structure of a multi-cavity mold, from
And make to can be produced at the same time multiple products in an injection cycle.And in the one set of die comprising it is a variety of it is of different sizes, into glue side
When the different product of formula, it usually will appear into the unbalanced phenomenon of glue, cause the scrappage of product high, and leverage production
The production efficiency of product, it is therefore desirable to optimize mould structure to solve the above problems.
Most common technical solution is, into throttle valve is arranged on glue faster a certain side runner, utilizes mold insert
The cross-sectional area of runner is adjusted in movement, thus make each die cavity to walk glue uniform.Although the technical solution structure letter
It is single, it is easier to realize, but there are certain risks；First is that lack enough fixed points since the bottom of mold insert is plane, it is single
Screw on mold insert is fixed it is difficult to ensure that adjustable range, is easy to appear the increase due to injection pressure and sends out the position of mold insert
Raw movement, influences the effect adjusted；Second is that operator is difficult rapidly to fix mold insert in place, generally require more
Secondary debugging；Even if successfully that mold insert is fixed in place, once mold insert is subjected to displacement in process of production, operator
It is difficult to for mold insert being fixed on original position.
Therefore, it needs to improve existing throttle-valve structure.
Utility model content
The purpose of the utility model is to provide a kind of throttle-valve structure for mold, which is able to solve existing
The problem of with the presence of technology.
To achieve the goals above, the technical solution of the utility model is:
A kind of throttle-valve structure for mold comprising: mode which is provided with runner；It is engaged mold insert, is connected to institute
It states on mode；Throttle mold insert, and one end is inserted in the runner, and the other end is connect with the occlusion mold insert；Locking member is used for
The occlusion mold insert and throttling mold insert are fixed on the mode；Length is additionally provided on the throttling mold insert or the occlusion mold insert
Hole, the locking member are arranged in the long hole, and the occlusion mold insert and throttling mold insert are fixed on the mode；The occlusion
The upper surface of mold insert be equipped with the first double wedge, it is described throttling mold insert lower end surface be equipped with the second double wedge, first double wedge with it is described
Second double wedge is mutually matched；When connection, first double wedge and second double wedge are intermeshed.
As a kind of specific embodiment, the throttling mold insert includes mold insert fixed block and choker bar, and the long hole is set to
On the mold insert fixed block, second double wedge is set to the lower end surface of the mold insert fixed block；The occlusion mold insert is equipped with solid
Determine hole, the fixation hole and the locking member are adapted.
Further, the width of the mold insert fixed block is greater than the width of the choker bar.
Further, the locking member is bolt；The bolt is successively arranged in the long hole, fixation hole, and with it is described
Mode is threadedly coupled.
As a kind of specific embodiment, first double wedge and second double wedge are along the length perpendicular to the long hole
Direction setting.
As a kind of specific embodiment, the tooth pitch of first double wedge and the second double wedge is 1mm.
Compared with prior art, the utility model has following technical effect that
The throttle-valve structure for mold of the utility model is grown by being arranged on occlusion mold insert or throttling mold insert
Hole, locking member are arranged in long hole and are fixedly connected with mode, so that occlusion mold insert and throttling mold insert are fixed on mode；It grasps simultaneously
Make personnel by adjusting position of the locking member in long hole, the length in throttling mold insert insertion runner is adjusted, to change in runner
The size of cross-sectional area reaches the function of adjusting flow velocity；Moreover, occlusion mold insert and throttling mold insert on be respectively equipped with the first double wedge and
Second double wedge, the first double wedge and the intermeshing of the second double wedge, even if can also consolidate under the action of the mold insert that then throttles is by injection pressure
Determine in place.
Further, throttling mold insert includes mold insert fixed block and choker bar, and choker bar is inserted in runner, and the second double wedge is set to
The lower end surface of the mold insert fixed block；The width of mold insert fixed block is greater than the width of choker bar, increases mold insert fixed block area then
The contact area for further increasing the first double wedge and the second double wedge makes throttling mold insert be able to bear bigger injection pressure.
In order to better understand and implement, according to the present invention will be described in detail below with reference to the accompanying drawings.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the throttle-valve structure of the utility model；
Fig. 2 is the longitudinal sectional view of the throttle-valve structure of the utility model；
Fig. 3 is the enlarged drawing in Fig. 2 at A.
