Description

Two-plate clamping mechanism

The utility model relates to a two-plate mold locking mechanism applied to injection molding machines, metal die-casting machines, profile extrusion machines and other equipment.

At present, most of the clamping mechanisms used in plastic processing, metal die-casting and rubber processing industries are three-plate type. During use, it is not easy to adjust the distance between the movable and fixed platen. There will be flashing in the hourly product, and excessive adjustment of the clamping force will be detrimental to all stress-bearing components; moreover, it is difficult to replace the mold, and the mass of each moving part is large, and it often fails to adjust during the mold adjustment process. For this reason, many people have improved the above-mentioned structure, such as the utility model patent "two-plate mold clamping mechanism" with the patent number 94226926. There are many inconveniences. If the adjustment is not good, the mold clamping force cannot be generated, and the positioning plate of the high-pressure oil cylinder will be damaged, which will bring a lot of inconvenience to the user.

The purpose of the utility model is to provide a two-plate clamping mechanism with only two templates and no mold adjusting device and supporting frame.

The utility model is realized through the following technical scheme: the mold shifting oil cylinder is fixed on the fixed formwork plate, one end of the pull rod is installed in the high-pressure oil cylinder on the fixed formwork, and the other end passes through the movable formwork and the rotating nut on it, and is placed in the high-pressure oil cylinder. , equipped with a piston adjustment device with a pull rod as a piston.

Because the utility model has only two locking plates, the structure is compact, the floor area is reduced, the cost is greatly reduced, and the mold is easy to replace and the time required for mold replacement is effectively reduced, so that the mold adjustment is labor-saving, stable and reliable.

Below in conjunction with accompanying drawing, the utility model is further described:

Accompanying drawing 1 is the utility model front view.

Accompanying drawing 2 is a side view of the utility model.

Accompanying drawing 3 is the schematic diagram of the opening state of the utility model.

See accompanying drawings 1, 2, 3, the utility model comprises thimble mechanism 1, rotating nut 2, moving template 3, mold 5, 7, pull rod 6, fixed template 9, high-pressure oil cylinder 10, piston adjusting device 11, guide rail 12, machine Seat 14, mold shifting oil cylinder 15, connecting rod 20, rotating oil cylinder 21. The fixed template 9 is connected with the machine base 14 as a whole, the movable template 3 is installed on the guide rail 12 on the machine base 14, the thimble mechanism 1 is fixed on the movable template 3, and the molds 5 and 7 are respectively installed on the movable and fixed templates 3 and 9 superior. Die-moving oil cylinder 15 is fixedly installed on the fixed template 9, and the other end is connected with movable template 3. One end of the pull rod 6 is installed in the high-pressure oil cylinder 10 on the fixed template 9, and the other end passes through the movable template 3 and engages with the rotating nut 2 on the movable template 3. Inside the high-pressure shaft cylinder 10, a piston adjusting device 11 with the end of the tie rod 6 as a piston is installed, and the rotating nut 2 is connected as a whole through the connecting rod 20. One end of the rotating oil cylinder 21 is fixed on the movable template 3, and the other end is connected with the rotating Nut 2 is connected.

The piston adjusting device 11 can be an oil cylinder, a servo motor, and the like.

When using the utility model, the movable template 3 is driven by the mold shifting cylinder 15 to move on the guide rail 12 to the tight position of the molds 5 and 7. At this time, the piston adjustment device 11 is started to adjust the pull rod 6 to a position suitable for the rotation of the rotary nut 2. , the rotating oil cylinder 21 pushes the rotating nut 2, and is driven by the connecting rod 20, so that the four rotating nuts 2 are turned to the position of locking the tie rod 6, and the high-pressure oil cylinder 10 is pressurized to generate the clamping force, and the injection can be performed at this time; cooling Finally, the high-pressure oil cylinder 10 releases the pressure, and the piston adjustment device 11 adjusts the pull rod 6 to a position suitable for the rotation of the rotating nut 2. The rotating oil cylinder 21 pushes the rotating nut 2, and is driven by the connecting rod 20. The four rotating nuts 2 turn to the open position and move. The template 3 is driven by the mold-moving cylinder 15, the molds 5 and 7 are gradually separated, and the ejector mechanism 1 ejects the molded product on the mold 5.
