点を有している。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a breaker plate device for an extruder for synthetic resin. The breaker plate is installed in front of the screw of the extruder almost orthogonal to the flow path of the molten synthetic resin, and holds the wire mesh for filtration and allows timely replacement, but there is a gap between the breaker plate and the mounting hole. When this occurs, the molten synthetic resin leaks due to the pressure of the extruder, and at the time of replacement, there is a drawback that it becomes difficult to pull out the breaker plate in which the viscosity of the resin has increased when the temperature has dropped.

る。The operation of this breaker plate device will be described. First, the breaker plate (6) to which the wire net (7) is attached is attached to the tip of the attachment shaft (10) by the pin (9), and the cylinder (12) is operated to operate the piston rod ( 13) is extended and the breaker plate (6) is inserted in the mounting hole (5) of the main body (1) (or the connector part (3)). At this time, the inclined surface (8) of the breaker plate (6) is attached to the mounting hole (5).
Insert to fit the inclined surface of. Then, while the breaker plate (6) is laterally pressed by the cylinder (12) and the molten synthetic resin is flown from the extruder body (1) into the flow path (4) by the screw (2), the molten synthetic resin is a wire mesh. It is filtered by (7) and enters the mold to be molded.

溶融樹脂が漏れる等のことは全くない。Thus, in the present invention, the contact surface (8) between the breaker plate (6) and the mounting hole (5) is inclined as described above, and the breaker plate (6) is inclined from the side to the inclined surface (8). Since they are pressed against each other, both sides of the breaker plate (6) are in close contact with the surface of the mounting hole (5) due to the wedge action, and no gap is created, so there is no possibility that the molten resin will leak even with the pressure of the extruder. Absent.

カープレート（６）の両側に設けてもよい。When replacing the wire mesh (7), the cylinder (12) is operated and the piston rod (13) is moved in the opposite direction, so that the breaker plate (6) can be taken out. It can be carried out. Also in this case, since the contact surface (8) between the breaker plate (6) and the mounting hole (5) is inclined as described above, the contact surface can be loosened and easily separated by just pulling out the breaker plate (6) slightly. It can be pulled out very easily. As the pressing means for the breaker plate (6), in addition to the air cylinder as shown in the figure, a suitable tightening device, a cam device, a rack and pinion device, or the like can be used. FIG. 3 shows an example of a tightening device, which includes a mounting plate portion (6 ′) in which a bolt (17) fixed to a support frame (16) of a main body (1) is provided on a side surface of a breaker plate (6). It is made to pass through and tightened with a nut (18). When the breaker plate (6) is pulled out after the extrusion work, the nut (18) is pulled out.
Then, a lever (not shown) having a hook shape or the like is inserted between the mounting plate portion (6 ') and the support frame (16), and the contact surface is separated with a slight twist, so that the contact surface can be pulled out as it is. Alternatively, the fastening means and the air cylinder (12) may be combined, the air cylinder may be used for insertion and removal, and the fastening device may be used for holding the plate (6). This fastening device may be provided on both sides of the breaker plate (6).
