[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses an extrusion mechanism for an extruder.

[0026] The utility model provides Figure 1-3 The extrusion mechanism for an extruder shown includes a processing table 1 and a support frame 2 fixedly arranged on the top of the processing table 1, a molding cavity 3 is fixedly arranged on the top of the processing table 1, a plurality of sliding holes symmetrically arranged are opened inside the processing table 1, baffles 4 are slidably penetrated in the plurality of sliding holes, and a plurality of baffles 4 are wrapped around the outer side of the molding cavity 3, an oil cylinder 5 is fixedly arranged on the top of the support frame 2, an extrusion block 6 is fixedly arranged at the end of the piston rod of the oil cylinder 5, the extrusion block 6 is arranged in cooperation with the molding cavity 3, an angle plate 20 is arranged between two adjacent baffles 4, and the angle plate 20 is fixedly connected to the top of the processing table 1.

[0027] When the aluminum profile is extruded, after the aluminum profile is placed inside the forming cavity 3, the oil cylinder 5 moves downward to drive the extrusion block 6 to enter the forming cavity 3. During this process, multiple baffles 4 move longitudinally to cover the outside of the forming cavity 3, and cooperate with multiple angle plates 20 to wrap the forming cavity 3, so as to avoid the aluminum profile from flying during the extrusion work and injuring the external operator, thereby improving the operating safety of the extruder. After the extrusion molding, when the extrusion block 6 moves upward, the multiple baffles 4 begin to move downward and open the forming cavity 3, so as to facilitate the removal of the formed aluminum profile.

[0028] In order to drive multiple baffles 4 to move synchronously to perform covering and protection work, such as Figure 1-2As shown, a pushing and protecting mechanism is provided between the outer lower end of the processing table 1 and the multiple baffles 4, and the pushing and protecting mechanism includes a reciprocating screw rod 7. A groove is provided at the outer lower end of the processing table 1, and the reciprocating screw rod 7 is rotatably arranged in the groove, and a push plate 8 is provided on the threaded sleeve of the rod wall, and the push plate 8 is in contact and connected with the bottom of the multiple baffles 4, and a through hole is provided on the groove wall to cooperate with the sliding of the push plate 8.

[0029] When the extrusion block 6 moves longitudinally, the reciprocating screw 7 is driven to move the push plate 8, and the push plate 8 can only move longitudinally under the sliding limit of the through hole. At this time, with the support of the push plate 8 on the bottom of multiple baffles 4, the push plate 8 can drive the multiple baffles 4 to move longitudinally synchronously, ensuring that the baffles 4 can perform stable protection work.

[0030] In order to ensure that the reciprocating screw rod 7 can be stably driven when the extrusion block 6 moves longitudinally, Figure 1-2 As shown, a connecting frame 9 is fixedly provided on the top of the extrusion block 6, a strip hole for the connecting frame 9 to slide is opened on the upper end of the side wall of the support frame 2, a vertical plate 10 is fixedly provided on the upper bottom of the connecting frame 9, a rack 11 is fixedly provided on the lower end of the vertical plate 10, a connecting block 12 is fixedly provided on the outer upper end of the processing table 1, a cross bar 13 is rotatably provided on the end of the connecting block 12, a circular gear 14 is fixedly provided on the rod wall of the cross bar 13, and the circular gear 14 is matched with the rack 11, a transmission mechanism is provided between the cross bar 13 and the reciprocating screw rod 7, the transmission mechanism includes a vertical rod 15, the vertical rod 15 is rotatably provided on the bottom of the connecting block 12, and a first bevel gear 16 is fixedly provided on the rod wall, a second bevel gear 17 is fixedly provided on the rod wall of the cross bar 13, and the second bevel gear 17 is meshed with the first bevel gear 16, the vertical rod 15 and the rod wall of the reciprocating screw rod 7 are fixedly provided with a pulley 18, and a belt 19 is provided for transmission between the two pulleys 18.

[0031] When the extrusion block 6 moves downward, the extrusion block 6 drives the connecting frame 9 to move downward. At this time, the rack 11 starts to move and gradually contacts and meshes with the circular gear 14, so that the circular gear 14 starts to drive the cross bar 13 to rotate. At this time, under the meshing of the second bevel gear 17 and the first bevel gear 16, the cross bar 13 rotates synchronously with the vertical rod 15, and drives the reciprocating screw 7 forward through the transmission of the pulley 18 and the belt 19. At this time, the push plate 8 moves upward longitudinally and pushes the baffle 4 to move upward for protection. After the aluminum profile is extruded, the extrusion block 6 moves upward. At this time, the connecting frame 9 drives the rack 10 to move in the opposite direction. At the same time, multiple components inside the transmission mechanism run in the opposite direction and drive the reciprocating screw 7 to rotate in the opposite direction. At this time, the push plate 8 moves downward, and multiple baffles 4 slowly move downward under the action of their own gravity and open the molding cavity 3, which is convenient for taking the molding material.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
