Description
Technical field
The utility model relates to punching press injection molding technical field, specially a kind of sequence opens and closes mode structure.
Background technique
In mold manufacture, it is related to many kinds of die sinking modes such as: two template dies, three template dies, cover half sliding block, dynamic model sliding block, cunning
Block is first stepped back into equal various structures.Different die sinking mode and die sinking sequence are respectively adopted according to product structure difference.
Cover half slide block structure and sequence are as follows: A B plate is using the connection of rubber shutter, due to the effect water of shutter when die sinking
Oralia is opened in advance, is opened after A B plate.Due to the rubbing action of shutter when molding, water gap plate is first closed, and is closed after A B plate.
A new product structure of company's exploitation at present is Z-type, and cover half sliding block is on dynamic model oblique top.Die sinking sequence are as follows:
Water gap plate is first opened, and sliding block retreats, and is opened after AB plate.Molding sequence are as follows: AB plate first closes, and closes after water gap plate, and sliding block enters.Sequence error
It will cause to hit mould accident.It is found in use at present in molding and die sinking due to the guiding mechanism, dynamic between AB plate
, there is certain frictional force in the mechanisms such as fixed mold core, die spacer block, general cavity jacking mechanism such as: spring, oil cylinder tool
There is unstable factor, be easy to cause and hit mould accident, mold damage.
Summary of the invention
In order to solve the problems, such as that the existing reliable sequence that cannot achieve is opened and molds, the utility model provides a kind of sequence
Mode structure is opened and closed, realization sequence open mold can be facilitated, extends die life.
Its technical solution is such that a kind of sequence folding mode structure comprising upper die mechanism and lower die mechanism, it is described on
Mold mechanism includes A plate, and the lower die mechanism includes B plate, is provided with water gap plate above the A plate, is provided with cover half in the A plate
Sliding block is provided with the oblique top with cover half sliding block cooperation on the B plate, which is characterized in that the water gap plate and the A plate it
Between connected by least two nitrogen gas springs, be provided with inclined hole on the cover half sliding block, the water gap plate bottom, which is equipped with, protrudes into institute
The sliding block shifting block of A plate is stated, sliding block shifting block bottom is provided with the skewback with inclined hole cooperation.
It is further characterized by being provided with the vertical hole with sliding block shifting block cooperation, outside the vertical hole on the A plate
Side is inclined-plane.
After the structure of the utility model, it is opened water gap plate in advance with A plate by the elastic force of nitrogen gas spring when die sinking,
Cover half sliding block exits below oblique top, then carries out AB plate die sinking, is stablized when molding by nitrogen cylinder elastic curve, stable working etc.
Feature molds AB plate in advance, and under the action of nitrogen gas spring, distance is protected before AB plate is closed completely between water gap plate and A plate
Hold it is constant, when cover half sliding block and oblique top completely in place after, nitrogen gas spring drives water gap plate to push so that cover half sliding block top again
Firmly oblique top realizes molding, conveniently realizes sequence open mold, extend die life.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Specific embodiment
As shown in Figure 1, a kind of sequence opens and closes mode structure comprising upper die mechanism 1 and lower die mechanism 2, upper die mechanism 1 include
A plate 3, lower die mechanism 2 include B plate 4, are provided with water gap plate 5 above A plate 3, cover half sliding block 6 is provided in A plate 3, is arranged on B plate 4
There is the oblique top 7 cooperated with cover half sliding block 6, connected between water gap plate 5 and A plate 3 by two nitrogen gas springs 8, is opened on cover half sliding block 6
There is inclined hole, 5 bottom of water gap plate is equipped with the sliding block shifting block 9 for protruding into A plate 3, and 9 bottom of sliding block shifting block is provided with oblique with inclined hole cooperation
Block 10 is provided with the vertical hole cooperated with sliding block shifting block 9 on A plate 3, and vertical hole lateral surface is inclined-plane, is convenient to the upper of sliding block shifting block 9
Lower movement.
Elastic force when die sinking by nitrogen gas spring is opened water gap plate in advance with A plate, and cover half sliding block exits below oblique top,
It carries out AB plate die sinking again, the features such as when molding is stablized by nitrogen cylinder elastic curve, stable working, molds AB plate in advance,
Under the action of nitrogen gas spring, distance remains unchanged before AB plate is closed completely between water gap plate and A plate, when cover half sliding block and oblique top
Completely in place after, nitrogen gas spring drive again water gap plate push so that cover half sliding block withstands oblique top.
Since the nitrogen gas spring used in the utility model has, small in size, elastic force is big, stroke is long, stable working, manufacture
Precision, long service life, spring curve is gentle, and advantages, overall simplification mold design and manufacture, the side such as does not need to pre-tighten
Mold installation and adjustment, extend the service life of mold.
