Abstract
The invention provides an ejector sleeve structure on the upper part of a top roller. The ejector sleeve structure has the advantages that an ejector sleeve can extend out of a top roller hole smoothly, the design cost of a mould is reduced, the structure is simple, and the fabricating cost is low. The ejector sleeve structure comprises a front mould and a rear mould, wherein the central interface of the front mould and the rear mould is of a sprue structure; the sprue structure is communicated with two side cavities; the rear mould is supported on a B plate. The ejector sleeve structure is characterized in that a composite structure of a thimble plate and a face needle plate is arranged below the B plate at interval of a cavity; the lower end of the face needle plate is supported by a supporting block on a base plate; the lower end of a material channel thimble is fixed in a centralized positioning cavity formed by the thimble plate and the face needle plate, and the lower ends of two side ejector sleeves are fixed in two side positioning cavities formed by the thimble plate and the face needle plate, respectively; the material channel thimble is arranged on the lower end surface of the sprue structure in a propping manner, and the two side ejector sleeves are respectively arranged on the lower end surface of the cavity of the corresponding side in a propping manner.
Description
Technical field
The present invention relates to the technical field of structures of product mold, the upper position that is specially top roller arranges the ejector sleeve structure.
Background technology
Existing mould is because the restriction of product structure just will go out ejector sleeve at place, rod hole site, top, and existing mould structure need to be made adjustment, to go out the position of ejector sleeve away from rod hole site, top, and make and need the redesign mould, its design cost is high, and complex structure, cost of manufacture is high.
Summary of the invention
The upper position that the invention provides top roller arranges the ejector sleeve structure, and it makes locates out ejector sleeve in the top roller hole site and can realize smoothly, has reduced the design cost of mould, and simple in structure, cost of manufacture is low.
The upper position of top roller arranges the ejector sleeve structure, its technical scheme is such: it comprises front mould, rear mold, described front mould, the interface place, center of rear mold is pouring gate structure, described pouring gate structure is communicated with the die cavity of both sides, described rear mold is supported on described B plate, it is characterized in that: after the cavity of one section, the interval, below of described B plate, be provided with ejector retainner plate, the combining structure of face needle plate, the lower end of described needle plate is supported on the back-up block on backing plate, the lower end of material road thimble is anchored on described ejector retainner plate, the formed centralized positioning of face needle plate chamber, the lower end of the ejector sleeve of both sides is anchored on respectively described ejector retainner plate, in the positioning chamber of the formed both sides of face needle plate, described material road thimble is mounted on the lower surface of described pouring gate structure, the described ejector sleeve of both sides is mounted on respectively the lower surface of the described die cavity of respective side, the mold insert thimble is positioned at corresponding described ejector sleeve, the top of described mold insert thimble is goed deep into respectively in the described die cavity of respective side, the bottom of described mold insert thimble is anchored in the installation cavity of described backing plate, described backing plate, be provided with lower ejector retainner plate installation cavity between base plate, described lower ejector retainner plate is positioned at described lower ejector retainner plate installation cavity, the upper surface of upper top roller is mounted on described ejector retainner plate, the face needle plate forms in positioning chamber, the lower surface of described upper top roller is supported on the upper surface of described lower ejector retainner plate, the lower central position of described lower ejector retainner plate has lower top roller hole, lower top roller runs through after described base plate the upper surface that is mounted on described lower top roller hole.
It is further characterized in that:
Described backing plate below is fastened with wear-resistant block, and the bottom supporting of described mold insert thimble is in the upper surface of described wear-resistant block.
After adopting structure of the present invention, lower top roller drives lower ejector retainner plate and rises, in promotion, top roller rises, and then promote ejector retainner plate, the face needle plate rises, complete the knockout course of product, it makes locates out ejector sleeve in the top roller hole site and can realize smoothly, has reduced the design cost of mould, and simple in structure, cost of manufacture is low.
