Abstract
A compression equipment possesses generality of various injection molding machine by which injection and mold under compression is performed. The compression equipment is composed as a unit and is installed between a moving die plate of the injection molding press and a moving mold. The compression equipment possesses a moving mechanism containing first tapered members moved by a cylinder and second tapered members contacting with the first tapered members and the moving mold moves toward a stationary mold by the cylinder.
Claims13
A compression molding assembly for an injection molding machine comprising;
- an injection compression molding machine having a stationary die plate attached thereto with a stationary mold, a moving die plate provided with a moving mold, the moving die plate being configured to move reciprocally to and away from the stationary die plate so that the moving mold moves to open and close toward the stationary mold and a mold clamping apparatus that reciprocally moves the moving die plate toward the stationary die plate;
- and
- a moving mechanism composed as a unit, installed between the moving die plate and the moving mold, the moving mechanism being configured to move the moving mold toward the stationary mold.
An injection compression molding machine, comprising:
- a stationary die plate with a stationary mold;
- a moving die plate provided with a moving mold, the moving die plate being configured to move reciprocally to and away from the stationary die plate, so that the moving mold moves to open and close toward the stationary mold;
- a mold clamping apparatus for reciprocally moving the moving die plate toward the stationary die plate;
- a compression assembly located between said moving die plate and the moving mold, the compression assembly being configured to compress the moving mold toward the stationary mold;
- and
- a contact member attached to one of the moving die plate and the stationary die plate to limit movement of said moving die plate toward said stationary die plate by said mold clamping apparatus by abutting thereof, so that compression and movement of the moving mold to the stationary mold by said compression equipment begins upon the termination of movement of said moving die plate toward said stationary die plate.
