A nasal impression assembly for use in prosthodontics and otolaryngology, wherein the assembly includes detachable components specifically designed for recording precise nasal impressions. The detachable components may include plurality of nasal cones, a pair of injection syringes, and an extra nasal mesh splint, assembled on a horizontal bar. Further a method is provided for measuring/imprinting the impression, by using the assembly, wherein an impression material is brought in contact with extra-nasal and/or intra-nasal structure to imprint its size and/or shape.

A process of overmolding a frame of a portable eyewear electronic device and a frame produced by the process is presented. A frame that includes a first material and includes a releasably mountable feature is attached to the mold in a desired position and does not contact other areas of the mold. The mold is filled with a second material to at least partially encase the frame insert.

Disclosed is an electric mould opening and closing system for an injection moulding machine, includes a mould opening and closing driving device including a mould transferring mechanism, a brake mechanism, a mould clamping mechanism and a brake auxiliary mechanism having a first state and a second state. When opening or closing mould, driven by the mould transferring mechanism, the brake auxiliary mechanism and the mould transferring mechanism make the movable plate move forward or backward in a horizontal direction, and the mould transferring mechanism is separated from the mould clamping mechanism by the brake auxiliary mechanism, and the brake auxiliary mechanism is in the first state. When braking, a linkage is formed between the brake mechanism and the mould transferring mechanism, the brake auxiliary mechanism is in the second state, and the mould clamping mechanism locks the movable plate.

A multifunctional soft pet paw cleaning cup includes a cup body made of a soft material. One end of the cup body is an open end. Soft spikes extending towards the center of the cup body are provided on the inner surface of the side wall and/or the inner surface of the bottom wall of the cup body, and the soft spike is made of a soft material. A mold for preparing the paw cleaning cup includes an inner mold core, an outer mold core, an upper mold and a lower mold. The outer mold core has an annular peripheral wall. A first soft spike hole is formed inside the peripheral wall. The inner mold core is provided at the inner side of the outer mold core. The lower mold is located below the outer mold core, and the inner mold core is fixed below the upper mold.

An injection molding device includes an injection machine, a molding die, and a high frequency oscillation device. The injection machine injects a resin material containing a dielectric heat generating material while keeping fluidity by temperature control. The molding die includes a cavity being a channel of flow of the resin material, and a pair of electrodes, each of which faces the cavity, the pair of electrodes being disposed to sandwich the resin material therebetween in a direction crossing a direction of the flow. The high frequency oscillation device applies a high frequency alternate-current voltage to the pair of electrodes.
