Description

  The present invention relates to a lamination molding apparatus capable of performing various lamination moldings with a single lamination apparatus.

  Conventionally, as a laminate molding device used to mold laminate molded products with multiple materials or multiple colors of resin, a fixed plate, a rotating plate and a movable plate are provided in the mold opening / closing direction between two sets of opposing injection machines. Is known (see Patent Document 1). This device has a fixed plate, a movable plate guided by a tie bar projecting from the fixed plate and movable in the mold opening / closing direction with respect to the fixed plate, and a mold opening / closing between the fixed plate and the movable plate. And a rotating disk provided so as to be movable in the direction, and the same male mold is attached to the surface of the rotating disk facing the movable disk and the fixed disk, respectively, and a female is formed in combination with the same male mold of the rotating disk to form different cavities. The mold is attached to a fixed platen and a movable platen respectively. In this laminating and forming apparatus, a rotating plate provided between the fixed platen and the movable platen is rotated, and the mold of the rotating plate is sequentially combined with the fixed plate and the female plate of the movable platen by a mold opening / closing operation, thereby successively different cavities. Then, from two sets of injection machines opposed to the movable platen side and the fixed platen side, a plurality of materials or a plurality of colors of molten resin are injected and filled one after another to form a laminated molded product. According to this laminated molding apparatus, primary molding is performed with a male mold attached to one surface of the rotating disk and a female mold attached to the movable disk, and at the same time, a male mold and a stationary disk attached to the other surface of the rotating disk. By performing the secondary molding on the primary molded product with the female mold attached to, one two-layer molded product can be obtained per mold opening / closing operation, and a laminated molded product can be obtained in a short cycle.

  However, in the laminated molding apparatus described in Patent Document 1, in addition to the arrangement in which the primary injection machine and the secondary injection machine are opposed to each other in the longitudinal direction of the apparatus, the primary injection machine is connected to the mold opening / closing operation of the movable platen. Since it advances and retreats in the opening and closing direction, that is, in the longitudinal direction of the apparatus, there is a problem that the entire length of the apparatus becomes longer than that of a conventional single layer molding apparatus. In addition, in order to mold one type of laminated molded product, it is necessary to provide a mold for each of the fixed platen and the movable platen, and to provide the same mold for each of the surfaces of the rotating plate facing the movable platen and the fixed platen. There is a problem in terms of versatility such that it is difficult to form a single layer or a single color.

  Moreover, the multiple injection molding apparatus described in Patent Document 2 is configured such that a plurality of movable molds are sequentially opposed to each other by a vertical movement with respect to a single fixed mold attached to the machine center of the fixed side mold plate. The structure that forms the mold cavity requires a space at least three times that of the movable mold in the height direction of the device, and the device itself becomes larger than the size of the molded product. There is a problem of being unsuitable. In addition, since one two-layer molded product is molded every two mold opening / closing operations, there is a problem that a molding cycle takes longer than the lamination molding apparatus described in Patent Document 1.

  These molding cycles and the number of molds are in an integrated relationship. If the molding cycle is shortened as in Patent Document 1, the number of molds increases, and the number of molds is decreased as in Patent Document 2. Since the molding cycle becomes longer as shown in the figure, the user usually compares these merits and demerits and selects the most suitable molding apparatus for the molded product to be laminated. However, with the recent shortening of the product life cycle, the molded product to be laminated is changed in a short period of time, and the molding equipment used does not meet the needs of the changed molded product, resulting in high molding costs. There is a problem.

  Accordingly, an object of the present invention is to provide a versatile laminate molding apparatus that can meet various needs of users with a single laminate apparatus.

As described above, in the lamination molding apparatus according to the present invention, the second injection unit is disposed so as to be movable in the mold opening / closing direction, and the second resin is injected and filled into any of the second cavity, the third cavity, and the fourth cavity. By making it possible, various molding methods such as single layer molding and multilayer molding can be performed with a single laminating device, and the molding conditions such as the number of molding cycles and the number of molds used can be accommodated. Therefore, it is possible to obtain a versatile laminate molding apparatus that can always adopt optimum molding conditions.

In addition, when the secondary injection unit 18 is previously positioned at a position aligned with the filling hole 27b formed in the fixed platen side mold 21a of the fixed platen 3, the secondary injection unit 18 is attached to the fixed platen side mold 21a. The operation of retracting from the filling hole 27b can be omitted.

[Second molding example]

Further, after the rotating plate 4 is held at a predetermined position and the movable platen 5 is opened to the mold opening limit position, the rotating plate 4 is rotated by the rotating plate rotating mechanism 11 at the predetermined position as shown in FIG. Thus, the secondary side mold 20b of the turntable 4 is switched to a position facing the fixed platen side mold 21b of the fixed platen 3.

  Next, as shown in FIG. 4 (d), the movable platen 5 and the turntable 4 are again closed, and the secondary mold 20 b of the turntable 4 is left in the primary molded body 43. The fixed platen side mold 21b of the fixed platen 3 is matched with the mold, and the mold clamping mechanism 14 moves the secondary side mold 20b of the rotating platen 4, the fixed platen side mold 21b of the fixed platen 3, and the movable platen 5. The board side mold 8b and the primary side mold 19b of the rotating board 4 are clamped. Thereafter, the secondary injection unit 18 is moved in the mold opening / closing direction by the moving mechanism 22 to a position where the secondary injection unit 18 is aligned with the filling hole 28 formed in the secondary side mold 20b of the turntable 4, and the secondary injection unit 18 is moved to the turntable. 4 is advanced in a direction orthogonal to the mold opening / closing direction so as to be in contact with the filling hole 28 of the secondary side mold 20b.
