Description

Double-plug-pin type die opening and closing sequence control mechanism

Technical Field

The application relates to the field of mold control technology, in particular to a double-plug-pin type mold opening and closing sequence control mechanism.

Background

Injection molds are common manufacturing tools currently used for plastic products, and are mainly used for injection molding of plastic products. The common injection mold mainly includes a two-plate mold, a three-plate mold, a hot runner mold, and the like. However, in the injection mold with double parting surfaces or multiple parting surfaces, the parting surfaces of the injection mold are often opened in a certain sequence due to the structure of the injection product. In the existing injection mold, a fixed mold plate and a movable mold plate are generally separated, and then the movable mold plate and a movable mold core are separated, so that the mold opening action is completed.

In the prior art, a swing hook parting mechanism is usually adopted to realize sequential die opening of the injection mold. The swing hook parting mechanism mainly comprises a swing hook, a spring, a roller and a stop block used for being matched with the swing hook, and the swing hook is rotatably arranged on the movable template. Then the check block is connected to the edge of the movable mold base plate 4 where the movable mold core is positioned, and the check block is positioned on the rotating path of the swing hook. The gyro wheel rotates and sets up in the fixed die plate, and the gyro wheel can roll and set up in the swing one end of keeping away from the dog, and the one end orientation that the movable mould board was kept away from to the swing hook corresponds the gyro wheel is buckled and is the arc to make the gyro wheel can drive the swing hook orientation and break away from the direction rotation of dog, the both ends of spring are connected respectively in swing hook and movable mould board simultaneously, in order to be used for ordering about the swing hook and rotate and hook and locate the dog.

In the die closing process, the movable die plate 5, the fixed die plate 6 and the movable die base plate 4 can move in opposite directions, in the process, the roller can roll towards the direction of the stop block along the swing hook, and when the roller rotates to one side of the arc bending part of the swing hook towards the stop block, the swing hook rotates towards the stop block under the action of the spring and hooks the stop block, so that the die closing is realized. Simultaneously when the mould is opened, because the swing hook is arranged on the stop block, the fixed mould plate 6 is separated from the movable mould plate 5, and the roller rolls along the swing hook towards the direction far away from the stop block. In the process that the movable template 5 and the fixed template 6 are opened and typed firstly; the gyro wheel can stir the pendulum hook and rotate towards the direction of keeping away from the dog to after the die sinking parting of movable mould board 5 and fixed die plate 6, the pendulum hook breaks away from the dog, makes movable mould board 5 and movable mould bedplate 4 parting again, thereby realizes the sequence control of die sinking in-process.

In the actual use process, however, the spring is needed to drive the swing hook to rotate, so that the sequential control in the mold opening process can be realized. Meanwhile, because the length of the swing hook is relatively long, the movable die base plate 4, the fixed die plate 6 and the movable die plate 5 need to be connected in a matching manner, so that the reliability of sequence control is reduced due to the fact that the rotation of the swing hook is easily interfered by the outside in the production and manufacturing process, and a relatively large space needs to be provided for the rotation of the swing hook.
