Description

Mould

Technical field

The utility model relates to a kind of mould, relates in particular to a kind of mould with accurate slide-and-guide property.

Background technology

Existing a kind of mould; Be used for the product that injection moulding has a side depressed part; This mould comprises a master mold, one and male model, an angled-lift splits and the ejecting mechanism of the mutual corresponding matching of master mold; This angled-lift splits is provided with the forming part that is used for moulding side depressed part, and angled-lift splits is arranged on the male model, also is provided with guide member on male model or the master mold.When male model and master mold die sinking, angled-lift splits breaks away from product through the guiding that is installed in the guide member on male model or the master mold, and ejecting mechanism ejects male model with product simultaneously.

But; Above-mentioned mould acts on the demoulding that could accomplish product simultaneously through guide member guiding angled-lift splits and the ejecting mechanism that is provided with on male model or the master mold; A plurality of workpiece cooperate and cause each workpiece slide displacement inaccuracy easily, the problem that the product button bit size that causes producing can not be assembled.

Summary of the invention

The purpose of the utility model is to overcome above-mentioned deficiency of the prior art, and a kind of mould with accurate slide-and-guide property is provided.

Be to realize above-mentioned purpose, the utility model provides a kind of mould, is used for the moulding plastics product, and this plastic product has a side depressed part, and this mould comprises a master mold, one and the male model and an angled-lift splits of the mutual corresponding matching of master mold.Master mold has a caster; Male model comprises a male model plate and an ejecting mechanism; Ejecting mechanism comprises a needle plate and an end needle plate that is positioned at male model plate below; Has an activity space between male model plate and the face needle plate; Make face needle plate and the end needle plate can be up and down on die sinking matched moulds direction, offer an oblique slide rail on the male model plate, place, face needle plate bottom offers one and dodges groove; Angled-lift splits is installed on the oblique slide rail slidably; This angled-lift splits is provided with the forming part that is used for moulding side depressed part; The forming part of angled-lift splits, master mold and male model can be enclosed to form a die cavity, and angled-lift splits upper end can be stretched into die cavity and be resisted against product, and the angled-lift splits lower end is inserted into to dodge and is resisted against in the groove on the end needle plate and can be in sliding perpendicular to mould die sinking direction in dodging groove; The angled-lift splits lower end outwards convexes with a rotational pin, and rotational pin is resisted against dodges groove upper end cell wall.

As stated; The utility model mould is equipped with through angled-lift splits and ejecting mechanism; Accomplish disengaging when making angled-lift splits in oblique slide rail, upwards eject product with the side depressed part; Eject and the demoulding with a workpiece completion, avoid a plurality of workpiece to cooperate the coarse problem of slide-and-guide property that causes, thereby improved the formed precision and the quality of product.

The specific embodiment

By the technology contents, the structural feature that specify the utility model, realized purpose and effect, know clearly below in conjunction with embodiment and conjunction with figs. and give explanation.

See also Fig. 1 and Fig. 2, the utility model mould is used for moulding plastics product 200, and this plastic product 200 has a side depressed part 201, and this mould 100 comprises a master mold 10, one and the male model 20 and an angled-lift splits 30 of master mold 10 mutual corresponding matching.

Said master mold 10 has a caster 11.

Said male model 20 comprises a male model plate 21 and an ejecting mechanism; Ejecting mechanism comprises a needle plate 231 and an end needle plate 232 that is positioned at male model plate 21 belows; End needle plate 232 is positioned at face needle plate 231 belows; Has an activity space between male model plate 21 and the face needle plate 231; Make face needle plate 231 and the end needle plate 232 can be up and down on die sinking matched moulds direction, offer a upper end on the male model plate 21 to away from side depressed part 201 lopsidedness and run through the oblique slide rail (indicating among the figure) of male model plate 21 upper and lower surfaces, place, face needle plate 231 bottoms offers one and dodges groove 2311.

Said angled-lift splits 30 is installed on the oblique slide rail slidably, and this angled-lift splits 30 is provided with the forming part 31 that is used for moulding side depressed part 201, and the forming part 31 of angled-lift splits 30, master mold 10 and male model 20 can be enclosed to form a die cavity (not indicating among the figure).Angled-lift splits 30 upper ends can be stretched into die cavity and be resisted against product 200; Angled-lift splits 30 lower ends are inserted into to dodge and are resisted against in the groove 2311 on the end needle plate 232 and can be in sliding perpendicular to mould die sinking direction in dodging groove 2311; Angled-lift splits 30 lower ends outwards convex with a rotational pin 32, and rotational pin 32 is resisted against dodges groove 2311 upper end cell walls.

During the utility model mold work, like Fig. 1 and shown in Figure 2, after male model 20 and the master mold 10 complete die sinkings; The face needle plate 231 and the end needle plate 232 of ejecting mechanism move upward together; End needle plate 232 upper surfaces pushing and pressing angled-lift splits 30 lower ends make angled-lift splits 30 tops along the oblique slide rail ejection product 200 that moves upward, simultaneously; Angled-lift splits 30 lower ends are in the horizontal slip in the groove 2311 of dodging of face needle plate 231; The forming part 31 of angled-lift splits 30 upper ends breaks away from the side depressed part 201 of product 200 gradually, breaks away from the side depressed part 201 of product 200 fully until forming part 31, and angled-lift splits 30 ejects product 200 fully; Then, mould begins matched moulds, and face needle plate 231 and end needle plate 232 move downward to return, simultaneously, dodges the rotational pin 32 of the upper end cell wall pushing and pressing angled-lift splits 30 of groove 2311, moves to return thereby drive angled-lift splits 30, and matched moulds is accomplished.

In sum; The utility model mould is equipped with through angled-lift splits 30 and ejecting mechanism; Accomplish disengaging when making angled-lift splits 30 in oblique slide rail, upwards eject product 200 with side depressed part 201; Eject and the demoulding with a workpiece completion, avoid a plurality of workpiece to cooperate the coarse problem of slide-and-guide property that causes, thereby improved the formed precision and the quality of product 200.
