Definitions

• Mold clamping unit for an injection molding machine for processing
• the invention relates to a mold closing unit for an injection molding machine for processing plastics and other plasticizable materials, such as ceramic or powdery materials, according to the preamble of claim 1.
• the present invention has for its object to provide a mold clamping unit that allows precise alignment of the mold carrier to each other.
• the support element now becomes the fixed point within the system, so that the previously stationary mold carrier is also movably supported in relation to the machine base.
• the support plate can be attached and adjusted at preferably three points on the machine frame or a part thereof.
• the angularity of the support element can be adjusted by the adjusting mechanism.
• the spar extension affects the "stationary" mold carrier so that it moves cyclically.
• the injection molding unit is firmly connected to this mold carrier, this does not lead to a reference problem with regard to the injection molding unit.
• FIG. 1 with a three-dimensional view of a plastic injection molding machine
• FIG. 2 shows a representation according to FIG. 1 with the mold clamping unit pivoted into the vertical position
• 3 is a three-dimensional view of the machine base with support element
• Fig. 4 is a representation of FIG. 3 with pivoted in the vertical position
• FIG. 7 is an enlarged, partially sectioned section of FIG. 6,
• Fig. 8 is a plan view of the machine base with the mold clamping unit removed.
• Figures 1 and 2 show an injection molding machine for processing plastics and other plasticizable materials such as ceramic or powdery materials with a mold clamping unit F and an injection molding unit S.
• the mold clamping unit horizontally arranged in Fig. 1 is pivoted into a vertical position.
• the swivel mechanism 20 required for this will be discussed later.
• the injection molding machine has a first mold carrier 10, to which the injection molding unit S is preferably attached. Furthermore, a further movable mold carrier 11 is provided, which is movable relative to the first mold carrier 10 by means of a mold closing mechanism C. A mold clamping space is provided between the mold carriers 10, 11, in which at least one multi-part injection mold can be received between the mold carriers, the parts of the injection mold 12 being releasably attached to the mold carriers 10, 11. A support element 13 is provided for the mold closing mechanism C. The mold closing mechanism C serves to cyclically open and close the injection mold 13 while moving the further, movable mold carrier 11 towards the first mold carrier 10 and away from it in the closing direction s-s of the injection mold 12.
• Mold-closing unit F and injection molding unit S are arranged on a machine base 14 and possibly a part of the machine base.
• the first mold carrier 10, the further movable mold carrier 11 and the support element 13 are mounted on the machine base.
• Force transmission elements which are provided as spars 18 in the exemplary embodiment, absorb the forces which occur during the positive locking and when the plasticizable mass is injected into the injection mold 12 between the first mold carrier 10 and the support element 13.
• a bow-shaped force transmission element can also be provided, which allows free access to the mold clamping space.
• FIG. 8 shows that the first mold carrier 10 is also mounted on the machine base or a part thereof in the closing direction SS. So that both mold carriers are movably mounted in the closing direction.
• the support element 13 is a stationary storage at the bearing points 17 on the machine base 14 or on a part thereof, such as. B. attached to the support member 15. Furthermore, an adjusting mechanism 16 (FIG. 7) is provided for adjusting the angle between the support element 13 and the machine base 14 or the part of the machine base. 7 and 8, the stationary mounting of the support element 13 on the machine base 14 or its part is spaced from the adjusting mechanism 16 in the closing direction SS. The stationary mounting of the support element 13 takes place at the bearing points 17, which are arranged on both sides of a center line mm and whose connecting line is at right angles to the closing direction SS.
• the two bearing points 17 and the adjusting mechanism 16 as the third point thus form a three-point bearing, which allows an exact adjustment of the support element with respect to the machine base.
• the support element is preferably formed from one piece, as is known from the earlier patent application DE 102 09 921. According to the solution there, the support element itself is also made in one piece and compact, so that there is a high dimensional accuracy of the contact surfaces. In principle, however, the adjusting mechanism 16 can also engage another part of the mold closing unit F, which is preferably in a fixed connection with the support element.
• the three-point bearing initially ensures that an arrangement at right angles to the center line of the injection molding machine is ensured via the bearing points 17, while the angularity of the plate can be set via the third point, that is to say via the actuating mechanism 16.
• the compact support element there is also a wide support base that also meets the requirements of vertical operation.
• the support element is inherently stable and there is no parallelogram, since the entire weight of the injection mold and mold carriers is supported centrally via the four bars 18 to the support element. This ensures optimal parallelism and centricity.
• the adjusting mechanism 16 is designed as a height adjustment for a part of the support element 13 that is spaced apart from the stationary bearing. Possibly. However, this part can also be a further part of the mold closing unit that is connected to the support element.
• Figures 2, 4, 6 and 7 show the arrangement of the mold clamping unit in the vertical position.
• a fixed arrangement of the support element without a pivot mechanism can also be provided, but in the exemplary embodiments the mold-closing unit, or at least the support element 13, is mounted on a part of the machine base 14, a pivotable support element 15.
• this support element 15 allows at least the mold closing unit F to be transferred from a horizontal position of the closing direction SS into a vertical position.
• the injection molding unit S can also be pivoted when it is attached to the first mold carrier 10, but in principle it is also possible to inject into the parting plane.
• FIGS 3 to 7 show the pivot mechanism 20.
• the support element 15 is rotatable in the pivot axis 19 relative to the machine base.
• the swivel mechanism 20 is mounted on the swivel axes 22, 23 on the support element 13 and on the machine base, so that when the swivel mechanism is actuated
• adjusting elements 25 can be provided on the contact surfaces 24 in order to adjust the system. 7 shows the attachment to the bearing points 17 and the adjusting mechanism 16 for the support element 13.
• bearing elements 26 for the first mold carrier 10 and a guide 27 for the further, movable mold carrier 11 are provided.
• these are arranged on a swivel table as a support element 15.
• the support element 15 carries the actual support element 13, since the mold carriers are guided directly onto corresponding surfaces of the machine base 14 vertical arrangement, the support is carried out anyway via the spars on the support element, so that further guidance of the mold carrier is not necessary.
