FIG. 3 is a view showing a state at the time of mold clamping of the injection molding machine according to the embodiment of the present invention.

  The injection molding machine 10 includes a frame 11, a fixed platen 12, a movable platen 13, a rear platen 15, a suction plate 18, a connecting rod 19, and a linear motor 21 as a mold opening / closing drive unit. The rear platen 15 corresponds to the fixed member described in the claims, and the suction plate 18 corresponds to the movable member described in the claims.

  The fixed platen 12 is placed on the frame 11 via the fixed platen support member 42 so as to freely advance and retract. A fixed mold 32 is attached to a surface of the fixed platen 12 facing the movable platen 13.

  The fixed platen 12 may be fixed to the guide block via the fixed platen support member 42, and the guide block may be movable along a guide laid on the frame 11. The guide of the fixed platen 12 may be the same as the guide of the movable platen 13. In this case, the fixed platen 12 is movable along the guide independently of the movable platen 13.

  The movable platen 13 is fixed to the guide block 14 via a movable platen support member 43, and the guide block 14 is movable along a guide (for example, a guide rail) 17 laid on the frame 11. As a result, the movable platen 13 can be moved forward and backward with respect to the fixed platen 12. A movable mold 33 is attached to the surface of the movable platen 13 facing the fixed platen 12.

  By moving the movable platen 13 back and forth with respect to the fixed platen 12, mold closing, mold clamping, and mold opening are performed. The fixed mold 32 and the movable mold 33 constitute a mold apparatus 30.

  The rear platen 15 is connected to the fixed platen 12 via a plurality of (for example, four) tie bars 16. The rear platen 15 is disposed between the movable platen 13 and the suction plate 18 and is fixed to the frame 11 via a rear platen support member 45. A through hole is formed in the center of the rear platen 15, and the connecting rod 19 is inserted through the through hole. The connecting rod 19 connects the movable platen 13 and the suction plate 18.

  In this embodiment, the fixed platen 12 can be moved forward and backward with respect to the frame 11 and the rear platen 15 is fixed with respect to the frame 11. However, the rear platen 15 can be moved forward and backward with respect to the frame 11, and the fixed platen 12 can be moved forward and backward. May be fixed to the frame 11.

  The suction plate 18 is connected to the movable platen 13 via the connecting rod 19 and moves together with the movable platen 13. The suction plate 18 is fixed to the slide base 20 via a suction plate support member 48, and the slide base 20 is movable along a guide 17 laid on the frame 11. As a result, the suction plate 18 can move forward and backward behind the rear platen 15.

  The linear motor 21 moves the movable platen 13 and the suction plate 18 connected via the connecting rod 19 with respect to the frame 11. The linear motor 21 is disposed, for example, between the suction plate 18 and the frame 11, and the propulsive force by the linear motor 21 is transmitted to the movable platen 13 through the suction plate 18.

  The linear motor 21 may be disposed between the movable platen 13 and the frame 11, and the propulsive force by the linear motor 21 may be transmitted to the suction plate 18 via the movable platen 13.

  The linear motor 21 includes a stator 22 and a mover 23. The stator 22 is formed on the frame 11, and the mover 23 is formed on the slide base 20. When a predetermined current is supplied to the coil of the mover 23, the mover 23 is moved back and forth by the interaction between the magnetic field formed by the current flowing through the coil and the magnetic field formed by the permanent magnet of the stator 22. . As a result, the suction plate 18 and the movable platen 13 are moved forward and backward with respect to the frame 11 to perform mold closing and mold opening. The arrangement of the coil and the permanent magnet may be reversed, and another coil may be used instead of the permanent magnet.

  As the mold opening / closing drive unit, instead of the linear motor 21, for example, a rotary motor and a drive unit including a ball screw for converting the rotary motion of the rotary motor into a linear motion, or a fluid pressure cylinder such as a hydraulic cylinder is used. Also good.

  The mold clamping force generation unit 24 includes the rear platen 15 and the suction plate 18, and generates a mold clamping force with the suction force of the electromagnet 25. One of the rear platen 15 and the suction plate 18 corresponds to the first block described in the claims, and the other corresponds to the second block described in the claims. The first block and the second block are relatively movable.

  A groove 28 for accommodating the coil 27 of the electromagnet 25 is formed around a predetermined portion of the attracting surface (rear end surface) of the rear platen 15, for example, the connecting rod 19, and a core 29 of the electromagnet 25 is formed inside the groove 28. The suction portion 26 is formed in a predetermined portion of the suction surface (front end surface) of the suction plate 18, for example, a portion surrounding the connecting rod 19 and facing the electromagnet 25. When a current is supplied to the coil 27 of the electromagnet 25, an attracting force is generated between the electromagnet 25 and the attracting portion 26, and a mold clamping force is generated. The core 29 and the adsorption part 26 may be formed of a magnetic material such as iron.

  The electromagnet 25 of this embodiment is formed as a part of the rear platen 15, but may be formed separately from the rear platen 15. Moreover, although the adsorption | suction part 26 of this embodiment is formed as a part of adsorption plate 18, you may form separately from the adsorption plate 18. FIG. Further, the arrangement of the electromagnet 25 and the attracting portion 26 may be reversed. That is, the electromagnet 25 may be formed on the suction plate 18 side, and the suction portion 26 may be formed on the rear platen 15 side. Further, electromagnets may be formed on both sides of the rear platen 15 side and the suction plate 18 side. A plurality of electromagnets may be formed on at least one side of the rear platen 15 side and the suction plate 18 side. The plurality of electromagnets constituting the mold clamping force generator may be individually controllable.

  Next, an injection molding method using the injection molding machine 10 having the above configuration will be described. The injection molding method includes a mold closing process, a mold clamping process, and a mold opening process.

  In the mold closing process, the linear motor 21 is driven to advance the movable platen 13. As shown in FIG. 2, the mold closing is completed when the movable mold 33 and the fixed mold 32 come into contact with each other. When the mold closing is completed, a predetermined gap δ may be formed between the rear platen 15 and the suction plate 18, that is, between the electromagnet 25 and the suction portion 26.

  In the mold clamping process, the electromagnet 25 is driven to generate an attracting force between the electromagnet 25 and the attracting portion 26. Due to this suction force, a clamping force is generated between the movable platen 13 and the fixed platen 12. A cavity space is formed between the fixed mold 32 and the movable mold 33 in the clamped state, and the molding material (for example, molten resin) is filled in the cavity space. The molding material filled in the cavity space is solidified and becomes a molded product.

  In the mold opening process, the linear motor 21 is driven to retract the movable platen 13. After the mold opening is completed, a molded product is ejected from the mold apparatus 30.

  Next, the mold clamping force generation unit 24 will be described in detail with reference to FIGS. 1 to 3 again. The rear platen 15 and the suction plate 18 are disposed on one side of the frame 11 (upper side in FIG. 3).

  The magnetic flux of the electromagnet 25 tends to pass easily. Since the frame 11 has a magnetic permeability higher than that of air, the balance of the magnetic flux density is lost and the balance of the attractive force is lost. Specifically, the upper suction force is stronger than the lower suction force between the rear platen 15 and the suction plate 18. As a result, a moment is generated in the rear platen 15 and the suction plate 18.

  Therefore, the rear platen 15 has a contact portion 15a that contacts the suction plate 18 at least at the time of mold clamping only at a part of the portion facing the suction plate 18. The contact portion 15a is formed only at the end portion (upper end portion in FIG. 3) opposite to the frame 11 of the portion of the rear platen 15 facing the suction plate 18. The rear platen 15 has a non-contact portion 15 b in the remaining portion of the portion facing the suction plate 18.

  Similarly, the suction plate 18 has a contact portion 18a that comes into contact with the rear platen 15 at least during mold clamping, only at a part of the portion facing the rear platen 15. The contact portion 18a is formed only at the end portion (upper end portion in FIG. 3) opposite to the frame 11 of the portion of the suction plate 18 facing the rear platen 15. The suction plate 18 has a non-contact portion 18 b in the remaining portion of the portion facing the rear platen 15.

  According to the present embodiment, the first block and the second block are in contact with each other during mold clamping, and the contact portion 15a of the rear platen 15 and the contact portion 18a of the suction plate 18 are in contact with each other during mold clamping. Therefore, a repulsive force is generated, and the moment due to the unbalance of the adsorption force can be reduced. Therefore, the burden on the rear platen support member 45 and the suction plate support member 48 is small, and the rigidity of the rear platen support member 45 and the suction plate support member 48 can be reduced. In addition, the loss of the balance of the adsorption force is less likely to cause the balance of the clamping force to be lost, and the balance of the clamping force is easily maintained.

  Note that the reason why the balance of the attractive force in this embodiment is lost is the presence of the frame 11, but the reason may be various. For example, when the suction force acts between the rear platen 15 and the suction plate 18, the lower end portion of the suction plate support member 48 is constrained, and therefore, the suction plate support member 48 with respect to the lower end portion of the suction plate support member 48. May be displaced forward, and the suction plate support member 48 may tilt forward. Then, the suction plate 18 tilts forward, the gap between the suction plate 18 and the rear platen 15 becomes non-uniform, and the balance of the suction force is lost. For the same reason, when the rear platen 15 tilts backward, the balance of the attractive force may be lost. The same applies to the following first to third modifications.

  The contact portion 15a of the rear platen 15 and the contact portion 18a of the suction plate 18 may be in contact with each other during mold clamping, and may not be in contact with each other when mold closing is completed. When the mold closing is completed, the suction surface of the rear platen 15 and the suction surface of the suction plate 18 may be perpendicular to the mold opening / closing direction. When at least one of the rear platen 15 and the suction plate 18 (the suction plate 18 in FIG. 3) is deformed due to the loss of the balance of the suction force, the contact portion 15a and the contact portion 18a can be brought into contact with each other.

  The gap δ at the completion of mold closing may be set narrow so that the contact portion 15a of the rear platen 15 and the contact portion 18a of the suction plate 18 come into contact with each other during mold clamping. The narrower the gap δ, the smaller the magnetic resistance, and a predetermined mold clamping force can be generated with less power.

  On the other hand, a gap is formed between the non-contact portion 15b of the rear platen 15 and the non-contact portion 18b of the suction plate 18 during mold clamping. Since only a part of the suction surface comes into contact, the repulsive force generated by the contact is smaller than the suction force, and a predetermined mold clamping force can be generated.

  In this embodiment, the contact portion 15a of the rear platen 15 and the contact portion 18a of the suction plate 18 do not contact when the mold closing is completed, but may contact when the mold closing is completed. For example, the suction plate support member 48 may be bent by the gravity acting on the suction plate 18, and the suction plate 18 may be tilted forward. Thereby, a part of the suction plate 18 and a part of the rear platen 15 may come into contact with each other when the mold closing is completed. Similarly, when the rear platen support member 45 is bent, the rear platen 15 may be tilted rearward, and a part of the rear platen 15 and a part of the suction plate 18 may contact each other. The same applies to the following first to third modifications.

  Note that the contact portion 15 a of the present embodiment is formed as a part of the rear platen 15, but may be formed separately from the rear platen 15. In this case, the rear platen 15 and the contact portion 15a constitute a fixed block, and the fixed block corresponds to one of the first block and the second block described in the claims. In this case, the contact portion 15a may be formed of any one of a magnetic material such as iron and a nonmagnetic material such as resin. The same applies to the following first to third modifications.

  Similarly, the contact portion 18a of the present embodiment is formed as a part of the suction plate 18, but may be formed separately from the suction plate 18. In this case, a movable block is comprised by the adsorption | suction board 18 and the contact part 18a, and a movable block is equivalent to either the 1st block and the 2nd block as described in a claim. In this case, the contact portion 18a may be formed of either a magnetic material or a nonmagnetic material. The same applies to the following first to third modifications.

  By the way, according to the present embodiment, the contact portion 15 a of the rear platen 15 is formed only at the end portion of the rear platen 15. Similarly, the contact portion 18 a of the suction plate 18 is formed only at the end portion of the suction plate 18. A repulsive force is generated at a position far from the center of the moment, and the moment is easy to reduce. The center of the moment and the center of the connecting rod 19 may have the same height from the frame 11.

  In the present embodiment, since the rear platen 15 and the suction plate 18 are substantially the same size, the ends of the rear platen 15 and the suction plate 18 come into contact with each other during mold clamping, but the rear platen 15 and the suction plate 18 are different. In the case of the size, any one of the end portions may be in contact with a part of the other. The same applies to the following first to third modifications.

  Further, according to the present embodiment, the contact portion 15 a of the rear platen 15 is formed only at the upper end portion of the rear platen 15. Similarly, the contact portion 18 a of the suction plate 18 is formed only at the upper end portion of the suction plate 18. Since the repulsive force is generated on one side of the connecting rod 19, the reduction in mold clamping force due to the repulsive force is smaller than when the repulsive force is generated symmetrically about the connecting rod 19. Most of the adsorption force can be used as mold clamping force, and the utilization efficiency of the adsorption force is good.

  In the present embodiment, the upper end portion of the rear platen 15 and the upper end portion of the suction plate 18 come into contact with each other, but the place of contact may be changed as appropriate according to how the balance of the suction force is lost. For example, the lower end portion of the rear platen 15 and the lower end portion of the suction plate 18 may be in contact with each other. Further, the side end portion of the rear platen 15 and the side end portion of the suction plate 18 may contact each other. Further, the outer peripheral portion of the rear platen 15 and the outer peripheral portion of the suction plate 18 may contact each other. The same applies to the following first to third modifications.

  FIG. 4 is a diagram illustrating a state at the time of mold clamping of the mold clamping force generation unit according to the first modification. The suction surface of the suction plate 18A according to the first modification has a step, and has a contact portion 18Aa and a non-contact portion 18Ab across the step. The contact portion 18Aa and the non-contact portion 18Ab can be partitioned by the step. The contact portion 18Aa and the non-contact portion 18Ab may be surfaces perpendicular to the mold opening / closing direction when the mold closing is completed. The contact portion 18Aa is formed at an end portion (upper end portion in FIG. 4) of the suction plate 18A opposite to the frame 11 in a portion facing the rear platen 15.

  According to this modification, the contact portion 15a of the rear platen 15 and the contact portion 18Aa of the suction plate 18A are in contact at least during mold clamping. Therefore, the same effect as the above embodiment can be obtained.

  In this modification, a step is formed on the suction surface of the suction plate 18A and no step is formed on the suction surface of the rear platen 15, but a step may be formed only on both suction surfaces or the suction surface of the rear platen 15. Good. In that case, the rear platen 15 may have a contact portion 15a and a non-contact portion 15b across a step. The contact portion 15a and the non-contact portion 15b can be partitioned by the step.

  FIG. 5 is a view showing a state at the time of mold clamping of the mold clamping force generating portion according to the second modification. The suction surface of the suction plate 18B according to the second modification has a vertical part perpendicular to the mold opening / closing direction when the mold closing is completed, and an inclined part inclined with respect to the mold opening / closing direction when the mold closing is completed. Has a contact portion 18Ba. Since the contact portion 18Ba is formed in a line shape or a dot shape and makes a line contact or a point contact, the contact area is small, the repulsive force is small, and the mold clamping force is large as compared with the surface contact. The contact portion 18Ba is formed at an end portion (upper end portion in FIG. 5) of the suction plate 18B opposite to the frame 11 in a portion facing the rear platen 15. The non-contact part 18Bb is formed in a part of the inclined part and the vertical part.

  According to this modification, the contact portion 15a of the rear platen 15 and the contact portion 18Ba of the suction plate 18B are in contact with each other at least during mold clamping. Therefore, the same effect as the above embodiment can be obtained.

  In addition, although the adsorption | suction surface of the adsorption | suction board 18B of this modification has an inclined part partially, you may have only an inclined part. The inclined portion including the contact portion 18Ba may be formed separately from the suction plate 18B.

  Further, the suction surface of the rear platen 15 of this modification has only a vertical portion perpendicular to the mold opening / closing direction when the mold closing is completed, but has an inclined portion inclined with respect to the mold opening / closing direction when the mold closing is completed. Alternatively, the contact portion 15a may be provided on the inclined portion. When the suction surface of the rear platen 15 has an inclined portion, the suction surface of the suction plate 18B may not have the inclined portion, and may have only the vertical portion.

  FIG. 6 is a view showing a state at the time of mold clamping of the mold clamping force generating portion according to the third modification. The rear platen 15C according to the third modified example includes a rear platen main body having a suction surface and a contact portion 15Ca attached to the rear platen main body. The contact portion 15Ca is formed at an end portion (upper end portion in FIG. 6) of the rear platen 15C opposite to the frame 11 in a portion facing the suction plate 18C. The non-contact portion 15Cb is the entire suction surface of the rear platen main body.

  Further, the suction plate 18C according to the third modification has a suction plate body having a suction surface and a contact portion 18Ca attached to the suction plate body. The contact portion 18Ca is formed at an end portion (upper end portion in FIG. 6) opposite to the frame 11 in a portion of the suction plate 18C facing the rear platen 15C. The non-contact portion 18Cb is the entire suction surface of the suction plate body.

  According to this modification, the contact portion 15Ca of the rear platen 15C and the contact portion 18Ca of the suction plate 18C are in contact with each other at least during mold clamping. Therefore, the same effect as the above embodiment can be obtained.

  As mentioned above, although embodiment of the injection molding machine was described, this invention is not limited to the said embodiment, A various deformation | transformation and improvement are possible within the range of the summary described in the claim. .

  For example, although the injection molding machine of the above embodiment is a horizontal mold whose mold opening / closing direction is a horizontal direction, it may be a vertical mold whose mold opening / closing direction is a vertical direction.
