Description
Technical field
The present invention is a kind of Novel injection mold of the umbrella stand ejector sleeve thimble demoulding of injection mold semi-positive, belongs to mold neck
Domain.
Background technique
Injection mold is the more universal usage of mold machine-shaping instantly, saves template and pushes up and down, and self-closing inner cavity
After the sizing of groove face template, need to only pour thermoplastic liquid enter inner cavity it is full after, in cooling, seamless spliced mold, plastotype effect
Rate is high, and flaw probability reduces, and quality is protected, and the common disadvantage to be optimized of technology has at present:
In the hot flow path and coolant flow channel of injection mold semi-positive, runner bonding phenomenon can be occurred by being molded to mold,
Runner mouth is caused to become being coupled blocking blocking with mold inside groove butt end, it, can be to viscous during the thimble of later period demoulding above pushes away
Agglomeration capping, and crackle is uneven, the block that results in blockage bends semi-ring frame mouth, and causing to turn up to interface edge struts internal diameter, makes running channel
The connection injection molding later period can excessively accumulate, allow after machine-shaping the pressure dynamics demoulded to be superimposed once more, sprue channel open is lost in internal pressure,
Continue plate and channel in sacrificial mold, influences injection volume and also change injection molding agglomeration amount, keep mold entirety projecting block big, again
Cause depanning agglomeration crackle uneven.
Summary of the invention

On the top of line jack-post 3I2 and axle center is conllinear, and the screw thread jack-post 3I2 is inserted embedded in the inside in the axle center torsional spring sleeve 3I3, described
Torsional spring sleeve 3I3 is the wide diameter column tube structure with oblique 45 degree of spiral endless tubes, engages mast then by inner tube wall screw thread
External spiral reed pipe forms the inner core pillar effect of about one pressure-bearing, ensures that coaxial core promotes rotating accuracy efficient, by tiltedly propping up
The solid ball cap block 3F3 spherical surface of strut 3F2 grafting rolls, and the effect of a bottom safe fastening in skidding top is formed, to pedestal department
Undertaking of cylinder or so contraposition balance is efficient.
Referring to Fig. 7, the double team frame ring 3F1 is by gasket ring 3F13 group in frame ring block 3F11, fan half ball cover 3F12 of plate, silica gel
At gasket ring 3F13 is nested with frame ring block 3F11 integral and in the same vertical plane in the silica gel, the fan plate hemisphere
The two sides up and down that cover 3F12 sets there are two and is respectively arranged in inside frame ring block 3F11, the half ball cover 3F12 of fan plate are hemisphere
Package is alternately superimposed the composite plate cover structure of narrow fan plate in type, and the deformation of a cast gate frame is formed by the alternate plate of thickness
Effect is tightened, and dimensioning is stablized, internal diameter deformation coefficient double team forces down, and wraps up in dottle pin silica gel by fan half ball cover 3F12 of plate
The cast gate that gasket ring 3F13 is tightened, when forming a depanning press, the effect that slagging block internal stress is born ensures that sandwiching frame mouth prevents
Deformation is pulled, remains the rounded corner size of cast gate.
Workflow: staff passes through the excessive umbrella stand of hydraulic square bearer 2 lock half by the way that thermoplastic liquid is imported piston boit cylinder 1
The pouring channel tube 3A of device 3 enters the inside of cubic shell slot 3C Yu injection molding cavity room 3D, then covers backform by plastotype gland cover 4
Board slot 3B forms a hot pouring modeling operation, then plugs interlocking bolt rod 5 to parting panel block 6 and the demoulding formation of spring groove seat 7
Interlocking reinjects condensate liquid and forms cooling and shaping, finally by the shearing bend pipe of umbrella stand thimble disk 3E in injection mould semi-positive
3E1 makes triangle convex 3E11 resist interior bend pipe chamber 3E12 friction and increases interior pressure to spring wire 3E13 and shearing batter post block
3E14 is formed flexible and is extended, and ensures that the thin fin arc plate 3E21 of fin clamping groove plate 3E2 resists the cubic liner slot 3E23 of anteposition,
Facilitate pedestal disc 3E3 to form a cone disk umbrella stand and lift injection molding part, the sliding shavings of the blade of disk is along knot when ensureing demoulding
Clinker, also make inverted trapezoidal groove body 3G and ejector sleeve seat 3H in the case where the needle point torus 3I1 and screw thread jack-post 3I2 of thimble casing 3I are turned round on
Lower pressurization is formed to torsional spring sleeve 3I3 goes up and down effect of pushing pin, and ejector sleeve is made to be dissipated into umbrella body to a coaxial core propulsive force has been withstood,
Double team frame ring 3F1 by sandwiching cue rack 3F protects runner cast gate, makes gasket ring 3F13 fastening frame in frame ring block 3F11 and silica gel
Mouthful, size is tightened, fan half ball cover 3F12 semi-packing type of plate maintenance injection molding interior conduit is also ensured, makes inclined support bar 3F2 bearing diagonal stream
Road passes through the gap friction rolling of rear solid ball cap block 3F3 and ball axial trough 3F4, reaches the fine tuning effect of lateral wing support, gives mold
Interior environment forming member maintenance, also ensures the quick of demoulding, processes injection molding part for injection mould semi-positive, there is one
Disk umbrella stand lifts operating effect.
The present invention is combined with each other by above-mentioned component, is reached and is matched with half excessive umbrella stand device 3 with plastotype gland cover 4
It closes, by ejector sleeve seat 3H grafting plastotype gland cover 4 and injection molding cavity room 3D, umbrella stand thimble disk is bonded at the bottom backform board slot 3B
3E, and shear bend pipe 3E1 and fin clamping groove plate 3E2 can extend receive it is folded, formed Pizza shape divide fanning tray stacking base disc 3E3 support
The even surface longitudinal edge dribbling blade cutting passage effect of act, forms one to sprue channel open edge and overlays boring cutter homogeneous agglomeration table
Face is cut, and then avris sandwiches cue rack 3F support running channel semi-positive inside cooperation inverted trapezoidal groove body 3G again, by sandwiching frame ring
3F1 carries out frame mouth packet pressure to injection mold, makes mold in injection moulding, and the interior stream of thermoplastic liquid is uniform, and later period agglomeration supports big
Deformation quantity is low, declines to the failure probability of mould inside channel internal diameter, while ensureing maintenance mould inner cavity, also to the knot of depanning
Clinker carries out cleaning and pushes away, and is solved in the hot flow path and coolant flow channel of injection mold semi-positive with this, carries out injection molding meeting to mold
Runner bonding phenomenon occurs, runner mouth is caused to become being coupled blocking blocking with mold inside groove butt end, in the thimble of later period demoulding
, can be to coherent mass capping during above pushing away, and crackle is uneven, the block that results in blockage bends semi-ring frame mouth, causes outside to interface edge
It turns over and struts internal diameter, so that the connection of running channel is molded the later period can excessively accumulate, and the pressure dynamics demoulded is allowed after machine-shaping to be folded once more
Add, sprue channel open is lost in internal pressure, continues plate and channel in sacrificial mold, influences injection volume and also change injection molding agglomeration amount, make
Mold entirety projecting block is big, and causes the problem of depanning agglomeration crackle unevenness.
Specific embodiment described herein is only to give an example to the present invention.The technical field of the invention
Technical staff can make various modifications or additions to the described embodiments or be substituted in a similar manner, but
Without departing from of the invention or beyond the scope of the appended claims.
