The invention relates to a crack-split moulding tool for producing a foam particle part, having two mould halves (2, 3). The mould halves (2, 3) are pivotably mounted relative to one another such that they can be arranged at a varying distance from each other in certain sections when being filled with foam particles and when pressing together, are moved together at a varying distance until in a closed position, due to a pivoting movement. As a result, it is possible to homogeneously compress areas of the moulding cavity (6) having a different thickness and to compress in a different manner, area having the same thickness.

Disclosed are a mould system and a clamping tong for securing a mould item part in a mould of a mould system. The clamping tong comprises: a primary tong segment comprising a primary clamping surface for applying clamping pressure on a clamping portion of a mould item part; a secondary tong segment coupled to the primary tong segment and comprising a secondary clamping surface for applying clamping pressure on a clamping portion of the mould. The clamping tong being configured to change between a clamping state and a release state, wherein the distance between the primary clamping surface and the secondary clamping surface in the clamping state is shorter than the distance between the primary clamping surface and the secondary clamping surface in the release state.

An apparatus and method for the automatic manufacturing of wind turbine blades, including an elongate tool support (2) with a main suspension beam (4), a plurality of support frames (8) supporting the main suspension beam (4) above the wind turbine blade mould (1), an elongate guide rail (5) provided on the main suspension beam (4) so as to extend longitudinally along the main suspension beam (4), a slider base (6) slidably mounted on the guide rail (5), a drive mechanism (53) for driving the slider base (6) longitudinally along the guide rail (5) and a tool holder (7) mounted on the slider base (6). The apparatus/method improves the efficiency and accuracy of the blade manufacture, and also reduces the exposure of the human body to harmful substances used in blade manufacture.

A mold for an ultra-thick walled U-shaped composite product with a deep cavity includes an upper mold cavity, a lower mold cavity, a slidable side-drawing insert, and an auxiliary mold clamping structure. The auxiliary mold clamping structure includes a first auxiliary mold clamping insert and a second auxiliary mold clamping insert. The first auxiliary mold clamping insert is fixed on the lower mold cavity, and the second auxiliary mold clamping insert is fixed on the slidable side-drawing insert. The slidable side-drawing insert is located on a side of an integral structure formed after the upper mold cavity is engaged with the lower mold cavity, and the slidable side-drawing insert longitudinally slides along the lower mold cavity. The ultra-thick walled U-shaped composite product is formed and located between the upper mold cavity, the lower mold cavity, and the slidable side-drawing insert.

A device for processing a particle foam material for producing a particle foam moulded part, comprising: at least one die apparatus, comprising a first die element and at least one additional die element, wherein the first die element is mounted so as to be movable along a movement axis relative to the at least one additional die element and/or the at least one additional die element is mounted so as to be movable along the or at least one movement axis relative to the first die element; at least one drive apparatus which is or can be assigned to the at least one die apparatus and is configured for generating and/or transmitting a drive force that sets the first die element and/or the at least one additional die element into a movement along the movement axis, wherein the least one drive apparatus is designed as or comprises a linear-drive apparatus.

A mold for forming a wind turbine blade comprising first and second mold surfaces including a flange portion having an opening therein, wherein the first and second mold surfaces are configured for relative movement therebetween from an open position to a closed position. The opening of the first flange portion is aligned with the opening of the second flange portion when in the closed position, and a first magnet is disposed within the opening in the opening of the first mold surface, and a second magnet is disposed within the opening of the second mold surface.

A mold die includes: a mold die body that is configured to hold an object to be molded, the object including a substrate and a chip mounted in a central area of the substrate, and that has a cavity which is rectangular in a plan view and which is configured to receive a resin material, the mold die body including: a pot for containing the resin material; a gate disposed at one side of the cavity and configured to allow the resin material to flow into the cavity; and a flow-path restricting mechanism that is disposed on both lateral sides of the cavity that are perpendicular to the one side and that is configured to narrow lateral flow paths, the lateral flow paths being flow paths for the resin material flowing through the cavity in which the chip is not disposed.

Disclosed is a microwave-transmitting mould structure, comprising a first template, a second template and a mould combining unit. The mould combining unit has a first snap fit, a second snap fit and an engagement member. The first snap fit is arranged on the first template; the second snap fit is arranged on the second template; and the engagement member is snap-fit engaged between the first snap fit and the second snap fit, so that when the first template and the second template are subjected to an outward pressure, corresponding faces thereof which the engagement member can pass through respectively abut against abutting faces of the first snap fit and of the second snap fit, and thus, the first template and the second template cannot be separated from each other due to an increased pressure inside the mould.

A single-acting, full return clamp (10) holds first and second objects, such as mold portions, in a compressive clamping relationship. A body (12), for attachment to the first object, has a housing (22) with first and second end plates (16, 18). A shaft (26) moves axially in the body and rotates about an axis of the body. A shaft end (32) outside of the housing bears against the second object in a first condition and disengages from the second object in a second condition, where the shaft end is lifts away from the body, and rotates relative to the axis. A spring (40) in the housing applies compressive force on the shaft in the first condition. A piston (74), in the housing near the first end plate when the device is in the first condition, moves axially against the spring force to move the shaft while in the second condition.
