  In the conventional molded product removal machine, the removal time per one cycle of the removal operation of the molded product removal mechanism is about 0.65 seconds. However, if the take-out time is further shortened in the conventional structure, the vibration of the mount becomes large, and this vibration causes a problem of deformation of the molded article taken out immediately after molding.

  An object of the present invention is to provide a molded article dispenser capable of speeding up the pickup operation more than in the prior art.

  A molded article dispenser to which the present invention is to be improved comprises a mount and a molded article pickup mechanism attached to the mount. A conventional gantry comprises a plurality of metal column members, a plurality of metal upper beam members connecting the plurality of upper ends of the plurality of metal column members, and a plurality of lower ends of the plurality of metal column members. A frame structure configured by respectively connecting metal lower beam members, and at least three metal side plates attached to the frame structure so as to block at least a part of four side openings of the frame structure; A metal top plate coupled to the frame structure to close at least a portion of the upper opening of the frame structure, and a metal bottom plate coupled to the frame structure to close at least a portion of the lower opening of the frame structure And a metal connecting member connected to the frame structure and connected to the forming machine. And a molded article taking-out mechanism is attached to a metal top plate. In such a molded product take-out machine, in the present invention, a combination of a plurality of metal column members and a metal upper beam member and a metal lower beam member, a frame structure and a metal top plate, a metal bottom plate and a metal side plate The connection of all is realized by welding. A plurality of metal intermediate beam members, which connect the plurality of metal column members at positions between the plurality of upper ends and the plurality of lower ends of the plurality of metal column members, are joined to the frame structure by welding. . Welded joints (joined structures formed by welding) have higher mechanical strength than bolted joint and threaded joint, and screwed and fitted joint. Therefore, the strength of the frame can be made higher than before. In addition, when metal intermediate beam members are joined by welding, the reference position (for example, the tip position of the extraction head, etc.) of the molded article extraction mechanism when the molded article extraction mechanism operates more than when there is no metal intermediate beam member The displacement can be halved. Therefore, the take-out speed can be made faster than before.

  The plurality of metal intermediate beam members may be composed of a plurality of outer intermediate beam members that connect a plurality of metal column members in the circumferential direction, or a plurality of outer intermediate beam members that connect a plurality of metal column members in the circumferential direction A plurality of outer sides are disposed in a space surrounded by a plurality of outer intermediate beam members and consist of an inner intermediate beam member connected with a plurality of outer intermediate beam members, or a plurality of outer sides circumferentially connecting a plurality of metal column members One or more insides arranged in a space surrounded by the intermediate beam member and the plurality of outer intermediate beam members and connecting two metal column members facing each other with the space among the plurality of metal column members It consists of an intermediate beam member. In either configuration, the displacement amount of the gantry when the molded product takeout mechanism operates can be halved as compared with the case where there is no metal intermediate beam member. In particular, when the inner intermediate beam member is provided, the mechanical strength can be enhanced and the displacement amount can be reduced by 18% or more as compared with the case where the inner intermediate beam member is not provided. Therefore, the removal speed can be further increased.

  It is preferable to further include a metal plate-like member joined to the upper or lower surface of the metal intermediate beam member by welding. When such a metal plate-like member is provided, the amount of displacement can be reduced by 5% or more compared to the case where it is not provided. Therefore, the removal speed can be further increased.

  A metal connection member is welded to two metal column members arranged along a forming machine of a plurality of metal column members, and the two metal column members are connected to the metal connection member. Preferably, the reinforcing beam members are welded. In this way, the displacement can be reduced by about 4% compared to the case where the reinforcing beam member is not provided.

  The molded product takeout mechanism is a drawout frame having one end attached to a metal top plate and extending in the mold opening and closing direction of the molding machine, and movably attached to the drawout frame via a linear guide mechanism along the drawout frame A first moving body that moves in a horizontal direction, an orthogonal frame that is attached to the first moving body, extends in a horizontal direction orthogonal to the extraction frame, and moves in a horizontal direction orthogonal to the extraction mechanism, It may be a structure provided with the 2nd moving body to move, and the pick-up head attached to the 2nd moving pull body. Of course, a molded article takeout mechanism having another structure can be used.

  Two metal column members sandwiching one side opening of the frame structure opposite to the extending direction of the drawing frame, and one side opening above the metal plate-like member It is preferable that the first metal side plate for closing the part of the part is joined by welding.

  The second metal column member that faces the two metal column members to which the reinforcing beam member is welded is the second metal that closes the side opening located below the metal plate member. Preferably, the side plates are joined by welding. In this way, the displacement can be reduced by 10% or more compared to the case where the first metal side plate is connected to the frame structure.

  Furthermore, a third metal side plate closing one opening is joined by welding to two metal pillar members sandwiching the one side opening of the frame structure located in the extending direction of the drawing frame. It is preferable that In this way, the displacement can be reduced by 40% or more compared to the case where the second metal side plate is connected to the frame structure.

  In the two metal column members to which the reinforcing beam members are welded and joined, a fourth metal side plate closing one side opening formed between the two metal column members is provided. Preferably, they are joined by welding. In this way, the displacement can be reduced by nearly 5% as compared to the case where the third metal side plate is connected to the frame structure.

  The metal column member, the upper metal beam member, the lower metal beam member, the intermediate metal beam member, the reinforcing beam member, the metal plate member, and the first to fourth metal side plates are iron-based members. It is preferably made of a material. If it is an iron-based material, the strength of the gantry can be maximized.

  Further, at least the drawing frame of the molded product taking out mechanism is preferably made of an iron-based material, but the orthogonal frame is also preferably made of an iron-based material. If these parts are made of an iron-based material, although the weight increases, it is possible to suppress the deformation of the molded product taking out mechanism and suppress the vibration of the drawing frame and the orthogonal frame.

  The drawing frame has a first outer surface extending in the extending direction of the drawing frame and extending in the vertical direction, and a second outer surface continuous with the first outer surface and intersecting the first outer surface. The linear guide mechanism is preferably configured such that the first outer side surface and the second outer side surface are installation surfaces on which the guide mechanism component is installed. In this case, the two forces acting between the linear guide mechanism and the pullout frame are directed in directions orthogonal to each other, and deformation of the pullout frame when the first moving body moves can be suppressed. As a result, it contributes to the reduction of displacement.

In this way, it is possible to suppress the deformation of the moving first moving body and to suppress the generation of the vibration, which contributes to the reduction of the displacement amount. Of course, the guide mechanism component installation wall may be made of an aluminum material if the required strength can be obtained due to its structure.
