Embodiment 1
Fig. 1 shows the structure diagram of arc core-pulling mechanism 10.
The present embodiment provides a kind of arc core-pulling mechanism 10, for carrying out core pulling to the circular arc product of injection molding.Circular arc
Core-pulling mechanism 10 includes power drive 101, circular arc guide groove 102 and circular arc core 103.Circular arc core 103 is oriented to circular arc
Groove 102 matches, and power drive 101 can drive circular arc core 103 to reciprocatingly slide in circular arc guide groove 102.
Circular arc product needs injection core in injection molding, and accordingly, injection core has equally with circular arc product
Radian.After moulding, it is necessary to which circular arc core 103 is extracted out, it is therefore desirable to by a kind of arc core-pulling mechanism 10 by circular arc
Core 103 is extracted out.Circular arc guide groove 102 matches with circular arc core 103, i.e. fortune of the circular arc guide groove 102 in circular arc core 103
On dynamic rail mark, the position of circular arc guide groove 102 is fixed.Circular arc guide groove 102 can allow circular arc core 103 to slide wherein,
It is new to circular arc to play guiding role so that circular arc core 103 extraction when, do not shift, it is therefore prevented that circular arc core 103 because
Core pulling is stuck, core pulling is deviated and collided with caused by product.
Circular arc core 103 is the cavity profiled part in injection molding, by power drive 101 to circular arc core 103
Apply active force, the position of circular arc core 103 is kept during injection, so as to ensure the accurate of the cavity of the workpiece of injection
Shaping, prevents the fluid power compressing of injection fluid and causes circular arc core 103 to be subjected to displacement.Existed at the same time by power drive 101
In time by circular arc core 103 by being extracted out on product after cavity shaping, so as to carry out modulus.When being molded next time, again
Circular arc core 103 is inserted into injection die cavities by startup power drive 101 to be prepared to be molded next time.
It follows that 101 one side of power drive plays the driving effect moved to circular arc core 103, on the one hand rise
The effect for keeping 103 position of circular arc core is arrived.
In the present embodiment, power drive 101 is linear drives part, and linear drives part is equipped with bar shaped sliding slot 1041, bar
The extending direction of shape sliding slot 1041 can synthesize the bending direction of circular arc guide groove 102 with the moving direction of linear drives part.
Since the direction of motion of linear drives part is straight line, the direction of motion of linear drives part is said by taking the vertical direction in scheming as an example
It is bright.In core pulling, the direction of motion of circular arc core 103 is the direction of circular arc guide groove 102, i.e., deflects diagonally downward.If so that
Linear drives part directly drives circular arc core 103 and moves, then the new component without horizontal direction of circular arc, thus can cause to justify
Camber core 103 moves stuck.Thus, bar shaped sliding slot 1041 is added on linear drives part, bar shaped sliding slot 1041 provides circle
The horizontal movement component of camber core 103, compensate for the mobile component of circular arc bending direction so that the extraction of circular arc core 103 is more
Add smooth.
Arc core-pulling mechanism 10 further includes STATEMENT OF FEDERALLY SPONSORED 104, and linear drives part driving STATEMENT OF FEDERALLY SPONSORED 104 does linear reciprocating motion,
Bar shaped sliding slot 1041 is arranged in STATEMENT OF FEDERALLY SPONSORED 104, and circular arc core 103 is slidably connected on bar shaped sliding slot 1041.Circular arc core 103
On can carry boss, boss is embedded in bar shaped sliding slot 1041, screw can also be connected with circular arc core 103, with screw
As sliding block so that bar shaped sliding slot 1041 can drive circular arc core 103 together to move.
During core pulling action, the angle of the moving direction of bar shaped sliding slot 1041 and linear drives part is into obtuse angle.With direction in scheming
On the basis of, during core pulling action, straight down, the tangential direction of circular arc guide groove 102 is tilts to the moving direction of linear drives part
Downwards, the movement locus of circular arc core 103 diagonally downward can be effectively synthesized using the bar shaped sliding slot 1041 tilted upward.
It should be noted that the length of the horizontal component of bar shaped sliding slot 1041 is not less than, the level point of circular arc guide groove 102
To length so that ensure linear drives part drive circular arc core 103 move when, circular arc core 103 is capable of smooth
Slided in circular arc guide groove 102.
103 one end of circular arc core is connected with product, i.e. 103 one end of circular arc core is inserted into injection die cavities, as injection
Core, molds the cavity of product.The other end of circular arc core 103 carries circular arc chamfering, in the present embodiment, circular arc core 103
The other end be equipped with sphere.The end of circular arc core 103 with circular arc chamfering is to circular arc core 103 to circular arc guide groove
Slip in 102 has good guiding role, is more advantageous to circular arc core 103 and slides into circular arc guide groove 102.
In another embodiment, 102 circle of position arc guide groove 102 of circular arc guide groove, circular arc core 103 are circular arc core 103,
Power drive 101 is circumference actuator, and circumference actuator driving circular arc core 103 reciprocatingly slides in circular arc guide groove 102.
The moving radius of circumference actuator is equal with the radius of circular arc guide groove 102, specifically the driving radius of circular arc actuator with
The radius of the center line of circular arc guide groove 102 is equal, without other linkage structures, directly drives circular arc core 103 in circle
Slip in arc guide groove 102, structure is simpler, and core pulling action is more smooth.
Embodiment 2
Fig. 2 shows the overall structure axonometric drawing of mould 1, and Fig. 3 shows the decomposition texture schematic diagram of mould 1.
The present embodiment provides a kind of mould 1, for the injection molding to product.Mould 1 includes the first template 11, the second mould
Plate 12 and circular arc core 103.First template 11 is equipped with circular arc guide groove 102, circular arc core 103 and 102 phase of circular arc guide groove
Matching, the second template 12 can do the linear reciprocating motion toward and away from the first template 11, and the second template 12 can drive circular arc type
Core 103 reciprocatingly slides in circular arc guide groove 102.
Active force is applied to circular arc core 103 by the second template 12, circular arc core 103 is kept during injection
Position, so as to ensure the accurate shaping of the cavity of the workpiece of injection, prevents the fluid power compressing of injection fluid and causes circular arc core
103 are subjected to displacement.At the same time by the second template 12 cavity shaping after in time by circular arc core 103 by being extracted out on product so that
Carry out modulus.When being molded next time, circular arc core 103 is inserted into standard in injection die cavities again by the second template 12
It is standby to be molded next time.
Second template 12 is moved towards the first template 11, and the first template 11 and the second template 12 engage, so as to mold, second
Template 12 drives circular arc core 103 to be inserted into preparation injection in injection die cavities.After moulding, the first template 11 deviates from first
Template 11 is moved, and the first template 11 and the second template 12 separate, so as to mold, the second template 12 drives circular arc core 103 self-produced
Deviate from product, and edge is slided in guide groove.
By the use of the second template 12 as linear drives part, in molding directly driving arc core is inserted into injection core
In, in die sinking directly driving arc core from product extracts out, work efficiency higher, and linkage is more preferable.
Mould 1 further includes STATEMENT OF FEDERALLY SPONSORED 104, and the second template 12 driving STATEMENT OF FEDERALLY SPONSORED 104 does linear reciprocating motion.STATEMENT OF FEDERALLY SPONSORED 104
