Provided is a magnetic clamp device that can be easily made into a state where a fall prevention function can be exerted when attaching adsorption objects.

A support member (20) is protruded horizontally from an upper part of a magnetic plate (7) of the magnetic clamp device. A protruding member (28) is protruded upward from a mold as an adsorption object that is adsorbed and fixed to an adsorption surface (8) of the magnetic plate (7). The mold (9) is arranged so that the engagement portion (32) faces the locking portion (27) with a predetermined gap above the locking portion (27) in a state where the mold (9) is adsorbed and fixed at a predetermined position on the adsorption surface (8).

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.

An operation screen of a magnet clamp is displayed on a controller of an injection molding machine. A mold clamping device of the injection molding machine is provided with the magnet clamp. The operation screen is for controlling the magnet clamp to perform clamping or unclamping of a mold.

A mold-clamping machine 10 includes a stationary mount 13, a movable mount 18, a mold-clamping mechanism 15 and a mold opening-and-closing mechanism 16. The mold-clamping mechanism 15 includes a cylindrical constraining mechanism 30. The constraining mechanism 30 has a magnet mechanism built therein. By causing a current to flow or not flow, the constraining mechanism 30 changes to an unconstrained state or to a constraining state. In the unconstrained state, the mold-clamping mechanism 15 is movable relative to a tie bar 19 and along the tie bar 19. In the constrained state, the mold-clamping mechanism 15 becomes unmovable relative to the tie bar 19. The magnet mechanism positions the mold-clamping mechanism at an arbitrary position over the tie bar.

An injection molding machine has a clamp that generates electromagnetic force and that secures a moving plate or a fixed plate using attractive force that is produced by the electromagnetic force; and a controller that controls separation force that acts on the moving plate or the fixed plate such that the separation force is less than the attractive force.

An injection molding machine has a clamp that generates electromagnetic force and that secures a moving plate or a fixed plate using attractive force that is produced by the electromagnetic force; a pressure sensor that is provided in the clamp, wherein the pressure sensor measures contact pressure that acts between the moving plate or the fixed plate and the clamp; and a controller for performing a measure to prevent detachment of the moving plate or the fixed plate based on the contact pressure.

A seal molding system may include a mold body having a mold inner geometry formed complementary to a fitting outer geometry of a fitting. The mold body may have a mold base formed complementary to a panel surface. The mold body may include an injection hole for injecting sealant into the mold cavity, and a vent hole for venting air and sealant from the mold cavity.
