Furthermore, the first die head, the second die head, the first support plate, the second support plate, the bus plate, the outlet template, the first cooling plate and the second cooling plate are fixedly connected through screws.
Furthermore, one end of the first core rod, one end of the second core rod, one end of the third core rod and one end of the fourth core rod, which are opposite to the feeding hole, are set to be in a conical structure.
Further, the parts of the main flow channel, which are positioned on the first die head and the second die head, are arranged into a conical structure.
Furthermore, the first core rod, the second core rod, the third core rod and the fourth core rod are both of two-section structures fixedly connected through screws, wherein the shorter section is positioned in the first cooling plate and the second cooling plate.
The utility model has the advantages that: use the utility model discloses the structure, extruder are extruded the material into the sprue, and with its cooling solidification after getting into trapezoidal shaping runner, guarantee the extrusion quality of board is moulded to wood better, have avoided the board is moulded to wood that the board is not fully stereotyped and is caused and take place to warp, influence the problem of outward appearance.
The present invention will be described in more detail with reference to the accompanying drawings and examples.
