Clamping unit for a molding machine, in particular for an injection-molding machine, with a machine frame, an end plate arranged on the machine frame, a platen movably mounted on the machine frame, a stationary platen arranged on the machine frame, at least two, in particular four, tie bars, via which a clamping force can be transmitted, and a mold height adjustment apparatus for adjusting the mold height for a molding tool which can be or is fitted on the platen, wherein the mold height adjustment apparatus has

i. a rotatable adjustment element gripping on at least one tie bar,
ii. a drive device for rotating the rotatable adjustment element and
iii. a locking device for securing the rotatable adjustment element against a rotational movement relative to the at least one tie bar.

The injection mold has a mold core including a first part and a second part. The parts are mobile relative to one another between a first injection position in which they are moved together to form an injection cavity permitting the injection of a material to form an injected part (50; 50′), and a second demolding position in which they are moved away from one another to permit the demolding of the injected part (50; 50′). The injection mold has at least one ejector designed to contribute to the demolding, and at least one movable intermediate plate (10; 10′, 20′), separate from the two parts of the mold core. The intermediate pate is arranged between the two parts of the mold core, and has at least one cutout (12; 12′, 22′) forming at least one part of the injection cavity of the injection mold.

A plastics cover for a motor vehicle includes a visible side, an inner side, and a carrier side. The carrier layer is composed of a transparent polymer material, which has a continuous and constant basic wall thickness and at least one of an arrow-shaped, tetrahedral, pyramidal, conical, or cuboidal recess at which at least one wall thickness variation is formed on the inner side of the carrier layer. The finishing layer which is arranged on a visible surface of the carrier layer. The finishing layer comprises a transparent polymer material.

Provided is a mold clamping device that can simplify the component count or structure by including a mold thickness adjustment mechanism that reduces the load on a power source, is easily maintained, and has high design flexibility. Also provided is a mold clamping device that can set a long distance (daylight) between molds without having to upsize the entire mold clamping device and can simplify the component count or structure. A mold clamping device for split molds includes a first platen, a second platen, a pressure receiving platen, and a mold thickness adjustment mechanism disposed on the pressure receiving platen. At least one of the first platen and the second platen is able to move back and forth so as to approach or depart from the other. The pressure receiving platen is located on a side remote from the first platen, of the second platen. The mold thickness adjustment mechanism includes a rod-shaped rotation member, a power source configured to rotate the rotation member around a rotation axis of the rotation member, the rotation axis being parallel to a longitudinal direction of the rotation member, and a pair of converters configured to convert rotation direction of the rotation member into a movement direction of the second platen. A mold clamping device for split molds includes polygonal first and second platens, a pressure receiving platen, and a toggle mechanism. At least one of the first platen and the second platen is able to move back and forth so as to approach or depart from the other. The pressure receiving platen is located on a side remote from the first platen, of the second platen. The toggle mechanism is disposed between the second platen and the pressure receiving platen and on a diagonal line of the second platen and configured to cause the first and second platens to approach or depart from each other.

The invention relates to a mould clamp for an injection moulding machine, comprising a device for automatically adapting to the mould height of injection moulds (13) of different heights (a). A clamping device supported on an adjustable supporting element (21) is provided for moving a movable mould carrier (11) in the clamping direction (s-s) towards and away from the stationary mould carrier (10). A distance (x) between the stationary mould carrier (10) and the adjustable supporting element (21) can be adjusted by moving the supporting element, by means of a mould height adjustment system (14). A locking device (16) detachably locks the supporting element (21) in the respective position thereof, by pretensioning locking elements. A dynamically actuatable mould height adjustment system is produced by the locking elements being selectively relieved or pre-tensioned by active actuating elements, the pretension being cancelled in order to release the mould height adjustment system (14).

A layer thickness regulating member includes: an opposing portion having an opposing surface to a peripheral surface of a developer carrying member; and a layer thickness regulating portion, projected from the opposing surface toward the developer carrying member, for regulating a layer thickness of a developer carried on the developer carrying member. The layer thickness regulating portion is integrally molded with the opposing portion. The layer thickness regulating member is, after being molded in a metal mold, separated by being pushed from a side opposite from the opposing portion of the layer thickness regulating member when the layer thickness regulating member is separated from the metal mold.
