Two spigot surfaces on block are respectively from matched moulds direction of motion institute into two different angles.
Further, the dynamic mould core is two side slide blocks, and the cover half is provided with two inclined slider waveguide rods；Two this is lateral
The relative both ends of sliding block are respectively equipped with a projection and a groove, and during matched moulds, two side slide blocks pass through projection and groove
Grafting is to realize accurate splicing.
Further, the locating piece is no less than two, at least provided with a locating slot on each side slide block.
Further, two locating pieces that can be inserted in respectively on two side slide blocks are a positioning block group；The locating piece group
Two locating pieces generally set relative to the die joint mirror image of two side slide blocks, and spigot surface on two locating pieces is adjacent sets
Put.
Further, two spigot surfaces close to two side slide block die joints are more than another two with matched moulds direction of motion angle
Spigot surface and matched moulds direction of motion angle.
The utility model sets locating slot, with height by setting locating piece on fixed mold corresponding to the dynamic mould core
The adaptation of locating piece and locating slot realizes the high accuracy positioning of fixed mold and dynamic mould core；Opposite sides two on the locating piece
Spigot surface realizes the positioning of left and right both direction, its positioning precision respectively from matched moulds direction of motion institute into two different angles
It is higher, small parting line or the effect without parting line can be achieved on the basis of existing processing.

To further illustrate each embodiment, the utility model is provided with accompanying drawing.These accompanying drawings are in the utility model discloses
A part for appearance, it can coordinate the associated description of specification to explain the running of embodiment original mainly to illustrate embodiment
Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and this practicality are new
The advantages of type.Component in figure is not necessarily to scale, and similar element numbers are conventionally used to indicate similar component.
The utility model is further illustrated in conjunction with the drawings and specific embodiments.
With reference to shown in Fig. 1 to Fig. 3, the embodiment provides a kind of high-precision injection molding mould, the injection for bulb valve element 1
Production, it includes dynamic model 3 and cover half 2, and cover half 2 is provided with fixed mold 20, the dynamic model 3 provided with the first side slide block 31 and
Second side slide block 32：
With reference to Fig. 2 to Fig. 4, the fixed mold 20 distinguish close to one end of dynamic model 3 towards first, second side slide block
Two locating pieces 21 have been protruded out, it is corresponding, the position of each locating piece 21 is corresponded on first, second side slide block 31,32
Provided with locating slot 33, the appearance profile that the inner chamber of the locating slot 33 adapts to the locating piece 21 is set, and during matched moulds, makes this
Locating piece 21 be inserted in corresponding in locating slot 32, you can to realize first, second side slide block 31,32, fixed mold 20
It is accurately positioned.
In conjunction with shown in Fig. 4 to Fig. 6, each locating piece 21 substantially cuboid, its relative two sides are distinguished
