Abstract

The utility model discloses an injection mold, comprising a first mold core and a second mold core which are locked together. At least one shallow slot runner and a plurality of cavities entirely or partially located in the slot runner are formed between the first mold core and the second mold core. The injection mold of the utility model connects the plurality of cavities via the shallow slot runner formed between the first mold core and the second mold core, in order to simplify the design of runner. Furthermore, the design and the manufacturing of the injection mold are convenient and the manufacturing efficiency can be promoted.

Description

Injection mold

Technical field

The utility model relates to a kind of injection mold, relates in particular to the injection mold in many caves, an a kind of chamber.

Background technology

Injection mo(u)lding is a kind of mode of production of industrial a large amount of uses at present, and in the structural design of injection mold, core and die cavity are critical components.At present, the design of core and die cavity is generally decided according to the size of product, and product is simple and the size I is designed to a multi-cavity mold type.

Usually flow passage structure need be designed very complicated between a plurality of die cavities of existing injection mold, thereby manufacturing has brought difficulty to mould, is unfavorable for enhancing productivity.

The utility model content

The purpose of this utility model is to provide a kind of and enhances productivity and easily manufactured injection mold.

For achieving the above object, injection mold that the utility model provides comprises one first die and one second die that snaps together, and encloses the more shallow shallow slot runner of at least one degree of depth and some all or part of die cavities that is positioned at this flow path groove between this first die and second die.

As mentioned above, the utility model injection mold couples together some die cavities by the shallow slot runner of enclosing between first die and second die, thereby has simplified the runner design, make this Injection Mold Design, make more convenient, thereby can enhance productivity.

The specific embodiment

By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.

See also Fig. 1, the injection mold 1 of this creation comprises one first die 10 and one second die 20.

See also Fig. 2, described first die 10 comprises one first template 11 and some first cores 12.This first template 11 is rectangular tabular, offers four flow path groove tops 111 that are square on first template 11.Described some first cores 12 are embedded on first template 11, and these first cores 12 are two rows, four column distributions on flow path groove bottom 111.Offer two runner tops 112 on first template 11, these runner tops 112 are extended with two branch flow passage tops 113 to flow path groove top 111.

See also Fig. 3, described second die 20 comprises one second template 21 and some second cores 22.This second template 21 also is rectangular tabular, offers four flow path groove bottoms 211 that are square on second template 21.Described some second cores 22 are embedded on second template 21, and these second cores 22 are two rows, four column distributions on flow path groove bottom 211.Second template 21 is provided with a sprue 23, and these sprue 23 ends extend to form a runner bottom 212 to both sides, and these runner bottoms 212 are extended with two branch flow passage bottoms 213 to flow path groove bottom 211.

See also Fig. 1 again, during injection mold 1 matched moulds, described first die 10 and second die 20 snap together, and enclose the die cavity 32 that the more shallow shallow slot runner 31 of four degree of depth and some all (also can be parts) be positioned at these flow path grooves between first die 10 and second die 20 respectively.Wherein, described flow path groove top 11 and flow path groove bottom 21 synthetic described shallow slot runners 31, the degree of depth of described shallow slot runner 31 is much smaller than the degree of depth of die cavity 32, and in the time of can guaranteeing that under the injection pressure effect of injection machine plastics are fully filled up die cavity 32, the degree of depth of shallow slot runner 31 is shallow more good more.After the formed product, after taking out product, injection mold 1 die sinking need to adopt the technology that cuts that required product is separated with waste material.

As mentioned above, the utility model injection mold 1 couples together some die cavities 32 by the shallow slot runner 31 of enclosing between first die 10 and second die 20, thereby simplified the runner design, make this injection mold 1 design, make all more convenient, thereby can enhance productivity.
