Description

Technical Field

[0001] The utility model relates to the technical field of die clamping frames, in particular to a double die clamping frame device for an extruder. Background Art

[0002] Extruders are a type of plastics machinery that originated in the 18th century. Extruder heads can be categorized as either right-angle or bevel-angle, depending on the direction of material flow and the angle between the screw centerline. Screw extruders rely on the pressure and shear force generated by the screw's rotation to fully plasticize and evenly mix the material. The material is then formed through a mold, which requires a clamping frame to close and squeeze the mold.

[0003] When using the existing mold clamping frame, the mold is usually placed in the mold clamping frame, and the cylinder is started to squeeze the mold to close the mold. After closing the mold, the mold is taken out and the mold can be closed with another set of molds. The mold closing work is only performed by one set of mold clamping frames, resulting in a lot of time required to close a large number of molds, which reduces the closing efficiency of the mold clamping frame.

[0004] According to the announcement number: CN220331875U, a mold frame for opening and closing a mold is provided, which includes a frame, a supporting plate connected to the frame for vertical sliding, an upper mold mounted on the supporting plate, a driving member for driving the supporting plate to slide vertically, a processing groove adapted to the upper mold is provided on the frame, a stripper plate is connected to the processing groove for vertical sliding, and a driving member for driving the stripper plate to slide vertically is provided on the frame, the driving member includes a plurality of force rods connected to the frame for vertical sliding, and a transmission assembly is provided between the supporting plate and the plurality of force rods. Therefore, when it is necessary to process the workpiece, the driving member drives the supporting plate to slide vertically, which can drive the upper mold to slide vertically. When the driving member drives the supporting plate to slide upward, the transmission assembly drives the force rods to slide upward, and the stripper plate slides upward to remove the workpiece, without the need to separately set up a driving member to disassemble it from the processing groove.

[0005] According to the mold clamping frame introduced above, when the mold is clamped, the clamping work is performed only through one combined mold frame, resulting in a large amount of time required to perform the clamping operation on a large number of molds, which reduces the clamping efficiency of the mold clamping frame. Therefore, we need to propose a double clamping frame device for an extruder. Utility Model Content

[0024] When closing the mold, the mold is placed on the jacking component 8, and the jacking component 8 is started to drive the mold to lift up and adjust the height of the mold. Then the extrusion component 10 at the top is started to extrude the top of the mold to complete the mold closing operation. Through the setting of the two-group mold base 7, the mold closing frame can simultaneously close the two groups of molds at a time. At the same time, through the cooperation of the moving component 12 and the adjusting component 11, the position and occupied space of the mold closing frame can be adjusted, which is convenient for installation in different environments, thereby shortening the time required for closing a large number of molds and improving the closing efficiency of the mold closing frame.

[0025] The lifting assembly 8 includes a synchronous lifter 81, which is fixedly mounted on the upper surface of the mold clamping base 7. The piston end of the synchronous lifter 81 is bolted to a support base 82. Starting the synchronous lifter 81 drives the support base 82 to move, so that the support base 82 lifts the top mold and moves it upward, so that the mold clamping height can be adjusted.

[0026] The top of the support seat 82 is fixedly connected to a support rod 13, and a support sleeve 14 is fixedly inserted into the surface of the mold base 7. The support rod 13 and the inner cavity of the support sleeve 14 are inserted and slid. Through the cooperation of the support rod 13 and the support sleeve 14, the four sides of the support seat 82 are positioned to avoid the angle deviation of the support seat 82 when it moves, thereby improving the stability of the support seat 82 when it is lifted.

[0027] The extrusion assembly 10 includes an electric cylinder 101, which is fixedly installed on the top of the fixing seat 9. The piston end of the electric cylinder 101 passes through the fixing seat 9 and is provided with a lifting seat 102. There are two groups of electric cylinders 101. When the electric cylinder 101 is started, the lifting seat 102 is driven to move downward. The bottom end of the lifting seat 102 contacts the top of the mold. The mold is closed by the cooperation of the lifting seat 102 and the support seat 82.

[0028] A through hole is provided on the surface of the lifting seat 102, and the inner cavity of the through hole of the lifting seat 102 is inserted and slid with the outer surface of the support column. Through the cooperation between the through hole of the lifting seat 102 and the support column, the four sides of the lifting seat 102 are limited to avoid the angle of the lifting seat 102 being offset after the mold is squeezed.

[0029] The adjusting assembly 11 includes a first electric push rod 111, which is fixedly mounted on the outer side wall of the mold base 7. The piston end of the first electric push rod 111 is fixedly connected to a moving block 112. The surface of the moving block 112 is fixedly connected to the outer side wall of the other combined mold base 7. The first electric push rod 111 is provided with two groups. Starting the first driving push rod drives the moving block 112 to move. The moving block 112 pushes the mold base 7 at the other end to move, so that the mold base 7 slides on the second slide rail 5 through the second slide 6. There are two groups of electric push rods. Through the cooperation of the two groups of electric push rods, the distance between the two combined mold bases 7 can be adjusted, so that the occupied space of the mold frame can be adjusted.

[0030] The moving assembly 12 includes a second electric push rod 121, which is fixedly installed on the top of the mold clamping base 1. The piston end of the second electric push rod 121 is fixedly connected to a connecting seat 122. The surface of the connecting seat 122 is fixedly connected to the outer wall of the support frame 4. The second driving push rod is started to drive the connecting seat 122 to move, so that the connecting seat 122 pushes the support frame 4 to move, so that the position of the mold clamping can be adjusted after the mold clamping frame is fixed.

[0031] When in use, the mold is placed on the support base 82, and the synchronous lifter 81 is started to lift the support base 82 and move it upward to adjust the height of the mold on the support base 82. Then, the electric cylinder 101 is started to drive the lifting base 102 to move downward. The lifting base 102 moves downward to fit the top of the mold. The lifting base 102 continues to move downward to squeeze the mold to achieve the mold closing operation. By setting the two-group mold base 7, the two groups of molds can be placed on the two groups of support bases 82 respectively when closing the mold, so that the two groups of molds can be closed synchronously.

[0032] During adjustment, starting the second electric push rod 121 can push the connecting seat 122 to move, and the connecting seat 122 drives the support frame 4 to move. The support frame 4 slides on the first slide rail 2 through the first slide 3, and the position of the support frame 4 on the mold clamping base 1 is adjusted. Then the first electric push rod 111 is started to push the moving block 112 to move, so that the moving block 112 drives the mold clamping base 7 to move, and the mold clamping base 7 slides on the second slide rail 5 through the second slide 6 at the bottom, thereby realizing the adjustment of the distance between the two combined mold bases 7, thereby shortening the time required for the mold clamping operation of a large number of molds and improving the mold clamping efficiency of the mold clamping frame.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
