An in-mold coat-forming mold and an in-mold coat-forming method are provided, wherein the mold prevents leakage of a coating material for the long term, which is likely to occur when the in-mold coat-forming method is carried out. By disposing a grove, a pressure piece, or both of them so as to serve as coating-material leakage-preventing means, in the vicinity of the edge of a mold cavity adjacent to a shear-structured engaging portion disposed along the circumference of the mold cavity, a coating material is prevented from leaking out of the mold from the engaging portion, and problems such as an adverse affect on a formed product caused by the leaked coating-material and a damage on the mold are prevented, whereby in-mold coat-forming is stably performed for the long term.

摘要:
To provide a spool for a coil winding device capable of preventing poor insulation caused by a leakage of coil wires without initially inserted coil wires staying at the vicinity of slot openings. A spool for a coil winding device of this invention includes a plurality of coil winding surfaces increased stepwise in diameter from the bottom upward in a state where the spool is disposed on the coil winding device. The spool includes a front spool part and a rear spool part, which are placed at a distance from each other so that each turn of coil has a length corresponding to arbitrary lamination thickness of the stator core. The plurality of coil winding surfaces includes a coil winding surface corresponding to the outermost coil that is formed so that a portion in a radial pattern from the vicinity of a portion corresponding to a central axis of the stator core towards an opening of the slot in which each coil is loaded is extended at least to a position corresponding to a core back where the roots of the teeth outside the slot of the stator core are connected.
摘要:
A process producing an in-mold coated molded product. The process molds a thermoplastic resin material under a mold-clamping pressure in a mold including a fixed mold part and a movable mold part each heated at a predetermined temperature, separates the fixed mold part and the movable mold part when the molded material surface is solidified such that it is durable to a pressure of injection and flow of a coating agent, and injects the coating agent containing a thermosetting resin material between an inner surface of the mold and the molded product obtained. The process also coats the molded product surface with the coating agent as the mold is re-clamped after injecting the coating agent, takes out the molded product coated with the coating agent when the coating agent is cured such that it is neither peeled off nor cracked by opening the mold, and re-heats the molded product after taking it out.
