A system for injection molding a part includes a plate, first and second primary mold slides, first and second secondary mold slides and at least a first core post. The first and second primary mold slides define an exterior of a first portion of a molded part and are movable relative to each other between an open position and a closed position. The first and second secondary mold slides define an exterior of a second portion of the molded part and are movable relative to each other between an open position and a closed position. A first core post defines an interior of the first portion of the molded part. The first and second secondary mold slides are operative to secure the molded part as the first and second primary mold slides are moved from their closed position to their open position, as the molded part is expanded under a source of pressurized air and as the first core post is withdrawn from an interior of the molded part.

A plastic molding system comprises: dispensing, pre-shaping and shaping cells and a transport subsystem. The dispensing cell has a station for dispensing a dose of plastic feedstock. The pre-shaping and shaping cells each comprise a plurality of stations for shaping the workpiece into a preform shape and into a final shape, respectively. The transport subsystem advances a workpiece along a selected one of a plurality of process paths to form a molded article. Each of the plurality of process paths is defined by a combination of stations of the dispensing cell, the pre-shaping cell and the shaping cell.

An ejection device having a pushing device that can be moved in translation along a first axis, an ejection element is translatable along a second axis different from the first axis, and a transfer device connecting the pushing device and the ejection element. The transfer device includes a transmission chain having at least two transmission links which are translatable in a sliding direction. The ejection device further includes an adjustment wedge mounted on the pushing device, the adjustment wedge having an adjustment surface forming an adjustment angle, with the transmission chain being mounted on the adjustment surface.

A slide assembly for injection molds includes a closing wedge, a slide body provided with a hole for at least partially housing said closing wedge, and a figure insert coupled to the slide body. The figure insert in the use position is vertically and horizontally movable with respect to the slide body. The slide assembly is both economical and simple.

Slider assembly for injection molds, comprising a slider body (1); a figure insert (2) coupled to the slider body (1); a slider rail (5) along which a rack (6) moves, said rack (6) being attached to the slider body (1); and a traction element (11) that moves a pushing element (8), the pushing element (8) being provided with teeth (9) that engage with the rack (6), so that the movement of the element The traction mechanism (11) causes the movement of the slider body (1) through the rack (6) and the pushing element (8). It allows providing a slider assembly for injection molds in which movement is reduced, requiring less space than in conventional slider assemblies.

An injection molding tool includes a \ primary mold cavity forming a handle sleeve having an inner circumference with an integral transition section attached thereto, and transitioning into a shaft protruding from the handle sleeve. The handle sleeve in an area between the attachment of the transition section and a free end facing the free end of the shaft has a skirt with an internally formed fastener for securing the handle sleeve to a container. The injection molding tool has an ejector-side insert and a nozzle-side insert removable for demolding purposes. The nozzle-side insert provides the part of the main mold cavity that molds the outer circumference of the handle sleeve, and the ejector-side insert.

A production mold for a split-type grit-textured packaging bottle includes fixed-mold and movable-mold assemblies. The fixed-mold assembly has top and bottom provided with injection channel and fixed-mold A plate respectively. Fixed-mold insert(s) installed in the fixed-mold A plate communicates with the injection channel, and corresponds to a concave cavity having bottom consistent with product's closed end in shape. Two inclined guide pillars are provided the concave cavity's two sides. The movable-mold assembly's top has a movable-mold B plate provided with a B-plate insert with a concave cavity-facing mold core. The B-plate insert's end relative to the product forms internally as an inverted cone structure. A pushing assembly includes a movable-mold push plate movable on the movable-mold B plate and having a top provided, relative to the concave cavity, with side sliders for correspondingly driving the guide pillars. Sliders'product-facing sides have structures matching grit texture on the product's outer wall.
