Abstract

The utility model relates to a rotary sprue insert which comprises a rotary insert, glass beads and springs. The surface of a fixing table of the rotary insert is provided with two round nests in the vertical direction; the center of the rotary insert has a through hole; the top end of the rotary insert has an inner hexagon hole and the inner hexagon hole is communicated with the through hole; a groove running through the surface is arranged on the inner hexagon hole; and the glass beads are arranged in the round nests and are fixed in a die by springs. The device has ingenious design, works stably, has compact structure and is convenient to process; on the premise of ensuring the accuracy of an injection molded part, the sprue insert is convenient to replace; the aim of conveniently producing two different products is achieved; the production cycle is shortened; the processing cost is reduced; and the safety is improved. The rotary sprue insert can be widely applied to the die for various products.

Description

A kind of rotary sprue mold insert

Technical field

The utility model relates to a kind of device of injection mold part processing, relates in particular to a kind of rotary sprue mold insert.

Background technology

Two kinds of different product designs are realized at a mold, to lower Die price to reach the more way commonly used of good utilisation resource, but when producing with mould, owing to the size of different product, the parameter that weight product is used identical injector, be difficult to guarantee the plastic injection quality of two kinds of products.Guarantee again product quality in order namely to reach sharing die, usually adopt mold removal after the single-piece production to change the mode of mold insert or stifled runner, but this kind mode, need to unload mould down again processing from injection machine, block original runner, open new runner, but will gain original product the time, unload down from injection machine again, block the runner of newly opening, gain original runner, troublesome poeration, delay the production time, mould and operator have also been increased a lot of danger.

Summary of the invention

Deficiency in view of the prior art existence, the utility model purpose is to provide a kind of and is guaranteeing under injection-moulded plastic part product appearance, dimensional accuracy and the prerequisite of die life, the rotary sprue mold insert that need not load and unload mould and be convenient for changing, the mold insert 90-degree rotation just can need only be reached the purpose of producing another kind of product, greatly facilitate production operation, shortened the production cycle.

For achieving the above object, the utility model adopts following technical scheme: a kind of rotary sprue mold insert, it is characterized in that: comprise rotation mold insert, bead, spring, the fixed station Surface Vertical direction of described rotation mold insert is provided with two round nests, the center is provided with through hole, the top is provided with inner hexagonal hole and communicates with through hole, and inner hexagonal hole is provided with the groove that connects the surface; Described bead is installed in the round nest, is fixed in the mould by spring.

This device design is ingenious, working stability, compact conformation, easy to process, under the prerequisite that guarantees the injection-moulded plastic part precision, be convenient for changing sprue mold insert, reach convenient purpose of producing two different products, shortened the production cycle, reduced processing cost, improved safety.Can be widely used on the mould of a mould multiple product.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As shown in the figure, a kind of rotary sprue mold insert comprises rotation mold insert 1, bead 2, spring 3, and the fixed station Surface Vertical direction of rotation mold insert 1 is provided with two round nests 11, and the center is provided with through hole 12, the top is provided with inner hexagonal hole 13 and communicates with through hole 12, and inner hexagonal hole 13 is provided with the groove 14 that connects the surface; During installation mold, rotation mold insert 1 is installed in the fixed head of dynamic model, bead 2 is installed in the round nest 11, is fixed in the mould by spring 3, and push rod 4 is installed in the through hole 12 of rotation mold insert 1.When using mould, mould is installed on the injection machine, bead 2 withstands in the round nest 11 in normal production process, keeps the stable of rotation mold insert 1.When changing when producing another kind of product, only need with die nut by force vertical rotation rotation mold insert 1 stop operating when bead 2 is stuck in round nest 11 to suitable position, guarantee to begin to produce behind stable under nature of rotation mold insert 1.
