Description
Technical field
It the utility model is related to plastic moulds technology industry, in particular to three plates with double-deck side core-pulling mechanism
Mould.
Background technology
A kind of tubular member as shown in Figure 1, it is transparent injection needle tube, and its both ends is respectively provided with external screw thread feature A,
The demoulding for external screw thread feature A is generally adopted by side core-pulling mechanism and is stripped；But on the straight body B of injection needle tube again
Parting line can not occur, therefore traditional integrated lateral core-pulling mechanism can not be used for the external screw thread feature of upper and lower ends.
Utility model content
The purpose of this utility model be to provide it is a kind of will not injection needle tube it is straight with to leave having for parting line double
Three template dies of layer side core-pulling mechanism.
To reach above-mentioned purpose, the technical solution of the utility model is as follows：
Three template dies with double-deck side core-pulling mechanism, mainly by double-deck side core-pulling mechanism, gate plate, middle plate and lower plate group
Into double-deck side core-pulling mechanism is made up of upper strata side core-pulling mechanism and lower floor's side core-pulling mechanism；The upper strata side core-pulling mechanism includes
One, oblique wedge one, sliding block one and screw top core tiltedly are carved, the sliding block one and the screw top core activity are placed on institute
The top of middle plate is stated, the screw top core is fixed on the side of the sliding block one, and the opposite side of the sliding block one is inclined-plane
One；It is described tiltedly carve one and the tiltedly wedge one be fixed on the bottom of the gate plate, the shape of the tiltedly side bottom of wedge one
It is engaged with the inclined-plane one, the one bottom oblique cutting tiltedly carved is in the tiltedly wedge one and the sliding block one；The lower floor
Side axle core mechanism includes tiltedly carving two, sliding block two and bottom thread core, and the sliding block two and the bottom thread core activity are put
Put at the top of the lower plate, the bottom thread core is fixed on the side of the sliding block two, the opposite side of the sliding block two
For inclined-plane two；Described tiltedly to carve two bottoms for being fixed on the middle plate, the two bottom oblique cutting tiltedly carved is in the sliding block two.
It is further that there is a mosaic block in the middle plate, there is die cavity and core, the type in the mosaic block
One end of core is inserted in die cavity, and the other end is fixed in thimble, and one end of the thimble is used for the bottom surface for being molded syringe, the other end
It is fixed in ejector retainner plate.
Compared with prior art, the beneficial effects of the utility model are：Upper strata side core-pulling mechanism is special to the external screw thread at top
Sign is stripped, and lower floor's side core-pulling mechanism is stripped to the external screw thread feature of bottom, can so be left at external screw thread point
Molded line so that product manufacturing meets the requirements.
Brief description of the drawings
, below will be to existing skill in order to illustrate more clearly of the technical scheme in the utility model prior art and embodiment
The required accompanying drawing used is briefly described in art and embodiment description.
Fig. 1 is a kind of structure chart of disclosed product in the prior art；
Fig. 2 is the disclosed sectional view using above-mentioned three template dies with double-deck side core-pulling mechanism of embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
Three template dies shown in Figure 2, mainly it is made up of, has double-deck side core-pulling mechanism, gate plate 1, middle plate 2 and lower plate 3
It is made up of three template dies of double-deck side core-pulling mechanism upper strata side core-pulling mechanism and lower floor's side core-pulling mechanism；Upper strata side core-pulling mechanism bag
Include and tiltedly carve one 4, oblique wedge 1, sliding block 1 and screw top core 7, sliding block one and screw top core activity are placed on middle plate
Top, screw top core is fixed on the side of sliding block one, and the opposite side of sliding block one is inclined-plane one；Tiltedly carve one and oblique wedge one
The bottom of gate plate is fixed on, the shape of the side bottom of oblique wedge one is engaged with inclined-plane one, tiltedly carves one bottom oblique cutting oblique
In wedge one and sliding block one；Lower layer side shaft core mechanism includes tiltedly carving 28, sliding block 29 and bottom thread core 10, sliding block two and bottom
Portion's thread core activity is placed on the top of lower plate, and bottom thread core is fixed on the side of sliding block two, the opposite side of sliding block two
For inclined-plane two；Two bottoms for being fixed on middle plate tiltedly are carved, tiltedly carve two bottom oblique cutting in sliding block two.
Screw top core and bottom thread core are molded the external screw thread at both ends respectively, and the straight body of syringe is by mosaic block 11
Die cavity and core 12 be molded jointly.Mosaic block is fixed in the middle plate, and one end of core is inserted in die cavity, and the other end is fixed
In thimble 13, one end of thimble is used for the bottom surface for being molded syringe, and the other end is fixed in ejector retainner plate 14.
After die sinking, gate plate is opened, and sliding block one breaks away to one in the presence of tiltedly carving one and gone, and screw top core follows cunning
Block with breakking away, realizes the demoulding of tip male thread one by one；Then, middle plate is opened, and sliding block two is in the presence of tiltedly carving two to one
Sideslip goes, and bottom thread core follows sliding block two together to break away, and realizes the externally threaded demoulding in bottom；Last ejector retainner plate stretches out,
