摘要： A cam slide retainer for injection molds includes a hardened wear plate with an elongated latch groove, mounted in a corresponding recess formed in the lower surface of the cam slide. The wear plate is aligned in the direction of travel of the cam slide and has a length that is no less than the length of stroke of the slide. A conventional spring-loaded plunger mounted adjacent the wear plate remains in contact with the wear plate throughout the stroke of the slide, so that the slide itself is not subject to wear from contact with the plunger.

摘要： Method and apparatus for control of a toggle operated press to effectively set relative position between a fixed platen and a die height platen. The toggle crosshead is placed at a position required to achieve a desired press clamp force. The die height platen is advanced toward the fixed platen until minute motion of the toggle crosshead away from the fixed platen is detected whereat advance of the die height platen is ceased. In the relative position of the die height platen and fixed platen results in contact of the mold sections prior to the crosshead being placed at the required position, the crosshead is retracted a predetermined distance and then advanced to the required position. Desired die height setting is achieved without repeated iterations of a die height setting procedure.

摘要： A mold clamp has a drive pivotally mounted on a first mold half. The drive includes a cylinder body and a piston, wherein one of the cylinder body or the piston is pivotally mounted to the first mold half and the other has a pair of pins and a locking plate having an engagement face. A guide directs the drive between a retracted position and an extended position. The guide has a pair of spaced apart guide plates mounted to the first mold half. Each guide plate has an arcuate slot slidably receiving the pins. An abutment is mounted on a second mold half. The abutment has a complementary engagement face for cooperating with the engagement face of the drive for enhancing engagement therebetween. When the drive is in the retracted position, the drive engages the abutment to apply a closing force between the first mold half and second mold half; when the drive is in the extended position, the drive is canted away from the first mold half allowing reciprocating relative motion between the first mold half and said second mold half.

摘要： The novel solution provides a closing part comprising an electromechanical drive for a CD injection molding machine having a working stroke and a servicing stroke. The entire mold closing unit is characterized by the combination of a short-stroke crank mechanism which is operated by an electric motor and which is provided for the working stroke and of a central electromotive column-type nut drive for the servicing stroke. According to the invention, synchronous motors or asynchronous motors are used with corresponding servo boosters to realize servo axles. The central column drive is used as a control element of the closing force control, together with a force sensor for detecting the closing force, as an actual value transmitter and as a control device.
