Embodiment 1

[0032] Such as Figure 1 to Figure 12 As shown, a two-plate mold clamping device includes a movable platen 1, a fixed platen 2, a mold shifting cylinder 3, a piston rod 4, a tie rod 5, a sliding foot 6, a piston back cover 7, a clamping piston 8, and a brake cylinder 9. Connecting connecting rod 10, connecting rod connecting seat 12, slider 13, ring tooth 14, guide sleeve 15, pull rod nut 18, mold breaking cavity 20 and mold locking cavity 21, the four corners of the fixed template 2 plane The tie rod 5 is fixed by the tie rod nut 18, the movable template 1 is installed on the tie rod 5, the mold transfer cylinder 3 is installed on the diagonal line of both sides of the fixed template 2, and the output end of the mold transfer cylinder 3 is connected to the corresponding side of the movable template 1, The four corners of the movable template 1 are piston back covers 7, and the mold locking piston 8 is installed in the piston back cover 7, and a transmission system is installe...

Embodiment 2

[0049] Such as Figure 7 ~ Figure 8 As shown, when the mold is closed, the mold shifting cylinder 3 pulls the movable template 1, and moves to the right along the pull rod 5 to close the mold. The connecting rod 10 drives the other mold locking piston 8 to rotate, so that the ring teeth 14 of the mold locking piston 8 and the ring teeth on the tie rod 5 change from the separated state to the meshing state, and the mold locking cavity 21 is oiled to push the mold locking The piston 8 moves toward the piston back cover 7, and forms the clamping force.

[0050] When the mold is opened, the clamping chamber 21 releases the mold clamping force, and the mold breaking chamber 20 enters the oil to push the mold clamping piston 8 into the piston back cover 7, and forms the mold breaking force to break the mold, and the output shafts of the two brake cylinders 9 move separately , to drive the mold clamping piston 8 to rotate, and at the same time, the connecting rod 10 drives the other...

Embodiment 3

[0053] Such as Figure 9 ~ Figure 10As shown, when the mold is closed, the mold shifting cylinder 3 pulls the movable template 1, and moves to the right along the pull rod 5 to close the mold. The connecting rod 10 drives the respective mold locking pistons 8 to rotate, so that the ring teeth 14 of the mold locking piston 8 and the ring teeth on the tie rod 5 change from the separated state to the meshing state, and the mold locking chamber 21 pushes the mold locking piston 8 with oil. Move toward the piston back cover 7 and form the clamping force.

[0054] When the mold is opened, the clamping cavity 21 releases the clamping force, and the mold breaking cavity 20 enters the oil to push the clamping piston 8 into the piston back cover 7, and forms a mold breaking force to break the mold, and the output shafts of the two brake cylinders 9 move, Drive the mold-locking piston 8 to rotate, and at the same time, the three connecting rods 10 drive the respective mold-locking pisto...

Abstract

The invention relates to a two-plate type mould locking device, which comprises a movable template (1), a fixed template (2), pull rods (5), mould locking pistons (8) and a band brake oil cylinder (9), wherein the pull rods (5) are fixed to the four corners of the plane of the fixed template (2) through pull rod nuts (18); the movable template (1) is arranged on the pull rods (5); a mould moving oil cylinder (3) is arranged at a diagonal position of edges on the two sides of the fixed template (2); an output end of the mould moving oil cylinder (3) is connected with the corresponding side edge of the movable template (1); piston rear covers (7) are arranged on the four corners of the movable template (1); the mould locking pistons (8) are arranged in the piston rear covers (7); and a transmission system is arranged on the mould locking pistons (8). The two-plate type mould locking device has the advantages of simple structure, simple control, less parts, low cost and high reliability.

Description

technical field [0001] The invention belongs to the field of mold clamping devices, in particular to a two-plate mold clamping device. Background technique [0002] The mold clamping devices used in injection molding machines and die-casting machines, one type is mechanical hydraulic type, and the other type is full hydraulic type, but no matter which type of mold clamping device, it requires high-speed mold opening and closing to reduce the movement time. In order to shorten the molding cycle and improve production efficiency, it also requires a large clamping force and sufficient force to resist the molding pressure required by the product. In order to meet the above requirements, various types of mold clamping devices are separated from the mold clamping piston and the brake, with many parts, complicated control and low reliability. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a two-plate clamping device, ...
