摘要： An armrest includes a base and an arm support. The base has a connecting portion and an installing portion. A first surface at an end of the connecting portion is opposite to the installing portion. The arm support is adapted to assemble with the base, and the arm support is pivotable with respect to the base. The arm support includes a second surface abutting the first surface, with a cavity defined in one of the first and second surfaces. An engaging member is pivotally received in the cavity in a single pivoting direction from an unlocked position to a locked position. The arm support is fixed to the base in the locked position.

摘要： An angular ejector mechanism for ejecting a plastic article with a recess in an inner side includes an angular ejector pin, a sliding pin, an elastic elements and a stopping block. The angular ejector pin includes a molding plate and a supporting plate. A moving hole and a sliding groove are respectively defined in a front face and an opposite rear face of the molding plate to communicate with each other. The sliding pin has a stopping protrusion dividing the sliding pin into a moving portion and a sliding portion. A sliding channel is defined on a front face of the stopping block. The sliding includes a vertical channel and a inclined channel. The moving portion is received in the moving hole of the molding plate, and the sliding portion slides from the sliding channel into the inclined channel until the angular ejector pin separates from the plastic article.

摘要： An injection molding apparatus includes a set of injection moulds and a set of cooling moulds. The set of injection moulds include a male injection mould and a female injection mould that are closed together to define an injection mould cavity. The set of cooling moulds include a male cooling mould and a female cooling mould that are closed together to define a cooling mould cavity. Molten plastic material is injected into the injection mould cavity to form a plastic article. The male injection mould and the male cooling mould are identical and interchangeable to enable the plastic article to be transferred to the cooling moulds. While the plastic article is accommodated in the cooling mould cavity and being cooled therein, molten plastic article is injected again into the injection mould cavity to form another plastic article. Thereby, the injection molding cycle time is reduced and the efficiency is improved.
摘要翻译：注射成型设备包括一组注射模具和一组冷却模具。该组注射模具包括一个公共注塑模具和一个阴模注塑模具，它们封闭在一起以限定注模模腔。该组冷却模具包括一个阳冷却模和一个阴冷却模，它们封闭在一起以限定冷却模腔。将熔融的塑料材料注入注射模腔中以形成塑料制品。男性注塑模具和阳式冷却模具是相同的并且可互换的，以使塑料制品能够转移到冷却模具。当塑料制品容纳在冷却模腔中并在其中冷却时，将熔融的塑料制品再次注入到注塑模腔中以形成另一塑料制品。因此，注塑周期时间降低，效率提高。
