Abstract

PURPOSE:To enable necessary resin amount supplied into an arbitrary rotatable mold to be automatically controlled, when a nozzle is opposed to this rotatable mold, by providing the regulation device changing a supporting position automatically by moving a movable frame, in between a stationary frame and the movable frame. CONSTITUTION:A motor 18 is driven, rotating rotatable molds 2A-2H, whereby a nozzle 12 is advanced and is caused to run into corresponding rotatable molds 2A-2H. The cylinder device 24 for feeding resin is contracted by way of a piston rod 25. The catalyzer in the reduced cylinder chamber is thrown into the rotatable molds 2A-2H by way of the nozzle 12. The supporting position regulating device 36 arranging the supporting position automatically by moving a movable frame 6 to oppose the nozzle 12 to an objective rotatable mold 1, is provided in between a stationary frame 1 and a movable frame 6. The resin in the cylinder chamber in the cylinder device 24 for feeding the resin is thrown into the rotatable mold 2A by way of the nozzle 12. Thus, the resin tube is obtained by centrifugal molding, throwing the resin and catalyzer into the rotatable molds 2A-2H.

According to this configuration of the present invention, by moving the movable frame, the resin supply nozzle can be made to correspond to one of the rotary molds arranged in parallel, and by inserting and removing the nozzle from the rotary mold, The amount of insertion/extraction movement is transmitted to the piston rod of the resin supply cylinder device via the swing lever, causing the piston rod to act, and the resin from the resin supply cylinder device is transferred to the rotating mold through the nozzle that is inserted/extracted. Can be supplied automatically. At that time, the pivot position adjustment device operates depending on the type of rotary type to adjust the pivot position of the swing lever, so there is a difference between the pivot position and the connection position of the swing lever and the piston rod. The length of the piston rod changes, which changes the stroke of the piston rod to automatically control the resin feed rate.

It is installed on the side. (4aA) and (48B) indicate springs that restrict the swinging of the L-shaped links (41A) and (41B). − The action is explained below. First, the movable frame (6) is raised and lowered by forward and reverse driving of the motor (9); the nozzle (6) is made to face the target rotating molds (gH) to (gH). Then, while rotating the rotary molds (2A) to (2H), the motor (to) is driven to move the nozzle (6) forward and plunge into the opposing rotary molds (2A) to (2H). At this time, since the nozzle (6) moves together with the slide body (2), both swinging levers (19A) (19B) connected to this slide body (B) via the connecting bottle (2) move along the vertical axis (2). 21A) (2

At the same time, the catalyst supply cylinder device (2) is contracted via the piston rod (to the piston rod), and the catalyst in the cylinder chamber to be contracted is introduced into the rotary molds (!A) to (2H) via the nozzle (to the nozzle). From the entry limit, the nozzle ring is reversed, ie withdrawn. This allows both swing levers (19A) (19B)
swings in the opposite direction to that described above, and as a result, the resin in the cylinder chamber of the resin supply cylinder device is injected into the rotary mold via the nozzle), and the catalyst supply cylinder device l- Refill the cylinder chamber with new catalyst. In this way, the resin and the catalyst are put into the rotary molds (2A) to (2H), and a resin tube is obtained by centrifugal molding as desired.

At 1, the cam roller (45AX45B) stops at its maximum operating state. In this case, multiple cam bodies (4
6A) and (46B) are adjusted so that the amount of protrusion toward the movable frame (6) is different. Therefore, the push-pull movement position of the push-pull levers (87A) and (87B) differs depending on the stop position. The movement of the push-pull rods (87A) (87B) is controlled by the swing links (89A) (j19B), rods C42A)C

According to the resin tube centrifugal molding equipment of the present invention having the above configuration, the following effects can be expected. In other words, by moving the movable frame, a nozzle for resin supply can be made to correspond to one of the rotary molds installed in parallel, and by inserting and removing the nozzle from the rotary mold, the punching process can be performed. The amount of movement is transmitted to the piston rod of the resin supply cylinder device via the swing lever, causing the piston rod to act, and the resin from the resin supply cylinder device is automatically transferred to the rotating mold through the nozzle that moves in and out. can be supplied to At that time, the pivot position adjustment device operates according to the type of rotary type (diameter change) and adjusts the pivot position of the swing lever, so the swing lever and piston rod are connected to this pivot position. The length between the two positions changes, which changes the stroke of the piston rod to automatically control the amount of resin supplied. In other words, although one resin supply means is compatible with a plurality of rotary molds, when it is made to correspond to any rotary mold, it is possible to automatically control the amount of resin needed for the rotary mold. can.
