Embodiment Construction
[0020] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0021] Such as Figure 1 to Figure 3 As shown, a hydraulic two-plate clamping device includes a fixed platen 1, a movable platen 2 and a reinforcing plate 8, and a linear guide rail is installed on both sides of the bottom of the movable platen 2 and the reinforcing plate 8, and the linear guide rail is installed on the machine bed 25 Above, the movable template 2 and the reinforcing plate 8 are slidably installed on the linear guide rail, the fixed template 1 is fixedly installed on the machine bed 25, and the movable template 2 and the reinforcing plate 8 move back and forth on the linear guide rail to realize mold opening and closing.
[0022] The four corners of...

The invention provides a hydraulic two-plate type mold locking device, and relates to the technical field of machining of injection molding machines, die casting machines, molding presses and the like. The mold locking device comprise a fixed mold plate and a movable mold plate, mold locking oil cylinders are arranged on the movable mold plate, mold locking piston rods are arranged in the mold locking oil cylinders, and one end of each mold locking piston rod penetrates through the movable mold plate at the corresponding one of the four corners of the movable mold plate and is connected to the fixed mold plate; and mold moving oil cylinders are arranged at the two ends of one diagonal line of the movable mold plate, mold moving piston rods are arranged in the mold moving oil cylinders, and the mold moving piston rods are connected to the fixed mold plate. The hydraulic two-plate type mold locking device has the beneficial effects that under the action of the mold moving oil cylinders, the movable mold plate quickly gets close to the fixed mold plate in a pulling manner to complete mold closing, after mold closing is completed, the four mold locking oil cylinders on the four corners of the movable mold plate complete high-pressure mold locking, and the hydraulic two-plate type mold locking device is good in structural stability, high in mold closing precision and balanced in stress. In addition, the mold moving oil cylinders arranged diagonally can increase the mold opening and closing speeds, so that the production period is shortened, and the production efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of injection molding and molding processing equipment, in particular to a hydraulic two-plate clamping device. Background technique [0002] Injection molding machine is also known as plastic injection molding machine or injection machine. It is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. It is divided into mechanical type, hydraulic type, machine-hydraulic hybrid type and all-electric type. The injection molding machine heats the plastic, applies high pressure to the molten plastic, and makes it shoot out to fill the mold cavity. The clamping device is used in the injection molding machine. The function of the clamping device is to ensure that the forming mold can be opened and closed flexibly, accurately, quickly, reliably and safely, to ensure that the mold cavity is tightly sealed and the plastic mel...
