Below, being described for implementing mode of the present invention with reference to accompanying drawing, in the drawings and in which, identical or corresponding symbol being marked to identical or corresponding structure and omits the description.The moving direction (being left in each accompanying drawing) of the screw rod 24 when filling is set to front, the moving direction (being right in each accompanying drawing) of the screw rod 24 when measuring is set to rear to be described.
[the 1st embodiment]
Fig. 1 is the figure injection (mo(u)lding) machine biopsy cavity marker devices of the 1st embodiment of the present invention illustrated.Injection (mo(u)lding) machine has base 12 and injection device 20.Injection device 20 is to filling molding material in die device.The guide 14 that injection device 20 is set to along being layed on base 12 is free to advance or retreat, and contacts with die device freely or be separated.
Such as shown in Figure 1, injection device 20 has cylinder body 22, screw rod 24, measure motor 26, injection motor 28, injection holder 30, slide 38, gyroaxis 40, finger plate 42 and support unit 60 etc.
Cylinder body 22 hot briquetting material (such as resin).The supply port 22a of moulding material is formed at the rear portion of cylinder body 22.The periphery of cylinder body 22 is provided with the heating sources such as heater.The front end of cylinder body 22 is provided with nozzle 23.
Screw rod 24 arranges as rotatable and free to advance or retreat in cylinder body 22.If make screw rod 24 rotate, then moulding material is sent to front along the spiral helicine groove of screw rod 24.Be melted gradually while moulding material forwards movement.Liquid moulding material is reserving at the front of screw rod 24.Thereafter, if make screw rod 24 advance, then the moulding material in screw rod 24 front penetrates from nozzle 23 and is filled in die device.
Measure motor 26 makes screw rod 24 rotate.The rotary motion of measure motor 26 is passed to screw rod 24 via bearing bracket stand 46 and connector 48 etc.Bearing bracket stand 46 together rotates with the rotor of measure motor 26.Bearing bracket stand 46 is connected with the rotor spline of measure motor 26, and free to advance or retreat relative to measure motor 26.Connector 48 connecting axle bolster 46 and screw rod 24.
Injection motor 28 makes screw rod 24 retreat.The rotary motion of injection motor 28 is converted to rotational motion to linear motion at ball screw framework 50, then is passed to screw rod 24 after the rectilinear motion being converted to bearing bracket stand 46.Ball screw framework 50 is made up of the ball-screw nut 52 being fixed on rear support 34 and the ballscrew shaft 54 that is screwed together in ball-screw nut 52.Be formed with rotating shaft 56 in the front end of ballscrew shaft 54, kept the bearing 58 of rotatably supporting rotating shaft 56 by bearing bracket stand 46.
The center line of the center line of cylinder body 22, the center line of screw rod 24, measure motor 26 and the center line of injection motor 28 are disposed on same straight line.
In addition, the mechanism rotary motion of measure motor 26 being passed to screw rod 24 can for varied.Such as, the center line of measure motor 26 can depart from the center line of screw rod 24, and the rotary motion of measure motor 26 can be passed to screw rod 24 via belt wheel or Timing Belt etc.
Further, the mechanism rotary motion of injection motor 28 being converted to the rectilinear motion of screw rod 24 can for varied.Such as, ball screw framework 50 converts the rotary motion of injection motor 28 to rotational motion to linear motion, but also can be converted to rectilinear motion.
Injection holder 30 is made up of front support 32, rear support 34 and connecting rod 36.Front support 32 is provided with the axial forward end portion of measure motor 26, and rear support 34 is provided with the axial forward end portion of injection motor 28.Connecting rod 36 is spaced apart and connect front support 32 and rear support 34.Injection holder 30 is equivalent to the installing rack described in patent requirements scope.
The guide 14 that slide 38 is set to along being layed on base 12 is free to advance or retreat.Injection holder 30 and slide 38 are together retreated.Thereby, it is possible to injection device 20 is retreated relative to die device, and nozzle 23 can be made to contact with die device or be separated.At the retrogressing extreme position of injection device 20, injection motor 28 more rearward can be given prominence to than base 12.
Rotating shaft 40 is disposed between slide 38 and injection holder 30, and injection holder 30 turns round centered by gyroaxis 40 relative to slide 38.Gyroaxis 40 can be arranged at slide 38 integratedly, also can be arranged at injection holder 30 integratedly.Because the front of injection device 20 is equipped with mold closing mechanism, therefore by change injection holder 30 towards, the maintenance (comprising exchange) of cylinder body 22 or screw rod 24 etc. can be made to become easy.
Finger plate 42 is disposed between injection holder 30 and slide 38.Injection holder 30 is installed on finger plate 42, and finger plate 42 slides freely relative to slide 38.The film of lubricant is formed between finger plate 42 and slide 38.In addition, injection holder 30 can be placed on finger plate 42 sliding freely, and finger plate 42 can be fixed on slide 38.
Support unit 60 supports injection motor 28 can make injection holder 30 pivotal mode centered by gyroaxis 40.Injection holder 30 towards changing, and easily to safeguard.Further, the distortion caused by the gravity being injected the injection motor 28 that frame 30 supports in cantilever fashion can be suppressed.When injecting motor 28 and more rearward giving prominence to than base 12, because the axial length injecting motor 28 is longer, therefore suppress the successful be out of shape.Now, also support unit 60 can be set to and compare base 12 and more rearward give prominence to.
As shown in Figure 1, support unit 60 is fixed in injection holder 30.When injection holder 30 carries out turning round or retreating, just can suppress to wear and tear with the position relationship of injection motor 28 without the need to changing support unit 60.
Support unit 60 has the guiding mechanism 62 of adjustment injection motor 28 relative to the position of center line of injection holder 30.Guiding mechanism 62 is such as made up of internal thread 64 and the external screw thread 66 that is screwed together in internal thread 64.External screw thread 66 is push injection motor 28 from below, and can suppress the distortion of the injection motor 28 caused by gravity.By making external screw thread 66 rotate relative to internal thread 64, the position of center line of injection motor 28 can be adjusted in the vertical direction.
[the 2nd embodiment]
Fig. 2 is the figure injection (mo(u)lding) machine biopsy cavity marker devices of the 2nd embodiment of the present invention illustrated.In the same manner as the support unit 60 shown in Fig. 1, the support unit 60A shown in Fig. 2 supports injection motor 28 can make injection holder 30 pivotal mode centered by gyroaxis 40.Injection holder 30 towards changing, and easily to safeguard.Further, the distortion caused by the gravity being injected the injection motor 28 that frame 30 supports in cantilever fashion can be suppressed.When injecting motor 28 and more rearward giving prominence to than base 12, because the axial length injecting motor 28 is longer, therefore suppress the successful be out of shape.Now, also support unit 60A can be set to and more rearward give prominence to than base 12.
As shown in Figure 2, support unit 60A support by slide 38, and together to retreat with slide 38.When injection holder 30 is retreated, just can suppress to wear and tear with the position relationship of injection motor 28 without the need to changing support unit 60A.
