Abstract

The invention discloses a rolling forming mold for hinge mounts of trunks. The rolling forming mold comprises an upper mold base and a lower mold base which are connected by guide columns, symmetric upper sliders are fixedly connected to two sides of the lower surface of the upper mold base, a pressing guide block is fixedly connected to the center of the upper mold base and is provided with an inner cavity, a spring and a pressing block are mounted in the inner cavity of the pressing guide block, the pressing block is in sliding fit with the pressing guide block, a concave mold is fixedly mounted in the middle of the lower mold base, two lower slider guide seats and protective covers are sequentially fixedly mounted on two sides of the concave mold, the lower slider guide seats are fixedly mounted and are symmetric relative to the lower mold base back and front, lower sliders are slidably mounted between the lower slider guide seats, rolling convex molds are fixedly connected to the inner ends of the lower sliders, and return springs are connected to the outer ends of the lower sliders and are fixedly mounted in the protective covers. A single-piece processing mode of an existing mold is changed into a double-piece processing mode, work efficiency is doubled, two sides of the mold are symmetrically stressed instead of an original mode that a single side of the mold is stressed, the problems that the existing mold moves difficultly and guide columns of the existing mold are bent and broken are solved, rolling convex mold guide columns are added, and the problems that the size of a punch is unstable and materials are withdrawn difficultly are solved.

Description

Boot hinge seat coiling mould

Technical field

The present invention relates to mould applications, concrete is a kind of boot hinge seat coiling mould.

Background technology

Existing hinge seat coiling mould, like Fig. 1, when patrix was descending, the elasticity binder block was pushed down part, went up oblique contract a and pressed down promotion slide block and volume circle, and there is following shortcoming and defect in this device:

1. monolateral stressed because of mould, cause mould to move; Guide pillar is crooked or fracture;

2. when rolling up the garden moulding, punch slide block b receives the resilience tension that part makes progress, and punch can't be resetted, and also causes the fracture of punch slide block simultaneously easily;

3. dimensional variations is bigger, and is extremely unstable.

Summary of the invention

The invention provides a kind of boot hinge seat coiling mould that can increase work efficiency, improve the stability and the product quality of mould greatly.

Technical scheme of the present invention:

Boot hinge seat coiling mould; Comprise upper and lower die holder; Connect through guide pillar between the upper and lower die holder, it is characterized in that: described upper bolster lower surface both sides are fixedly connected with the top shoe of symmetry, and central authorities are fixedly connected the binder guide pad; This binder guide pad inner hollow also is equipped with spring and binder block, and binder block and binder guide pad are slidingly matched; The middle part of described die shoe is installed with die; The both sides of die all are installed with sliding block guide holder, protective cover successively; Described sliding block guide holder be hard-wired, about two of symmetry before and after the die shoe, be slidingly fitted with sliding block between it, described sliding block the inner is fixedly connected with volume boss mould; The outer end connects back-moving spring, and described back-moving spring is fixedly installed in the described protective cover.

Described boot hinge seat coiling mould, it is characterized in that: the both sides of described die are installed with the punch guide pad, and punch guide pad middle part is provided with through hole, and described volume boss mould passes this through hole, is slidingly matched with it.

Described boot hinge seat coiling mould is characterized in that: be installed with the slide block backing plate between described sliding block and the die shoe, on die shoe, described sliding block slides on described slide block backing plate.

Described boot hinge seat coiling mould is characterized in that: have the fixed guide groove on the described die, and workpiece portion placed within, and described volume boss mould slides along it.

Described boot hinge seat coiling mould is characterized in that: when mould is not worked, the outer end of sliding block, be positioned at and be installed with baffle plate on the die shoe, this baffle plate contacts described upper and lower slide block simultaneously.

The present invention has the following advantages:

1. change two part processing into by single-piece work, operating efficiency doubles;

2. stressed to become bilateral symmetry stressed by monolateral for mould, solved the problem that mould moves and the guide pillar bending fractures;

3. increase volume boss mould guide pad, solved the drift size instability and material returned difficulty.

The specific embodiment

Referring to accompanying drawing; Boot hinge seat coiling mould comprises upper and lower die

holder

5,6, upper and lower die holder 5, connects 17 through guide pillar between 6; Upper bolster 5 lower surface both sides are fixedly connected with the top shoe 1 of symmetry; Central authorities are fixedly connected binder guide pad 2, and these binder guide pad 2 inner hollow also are equipped with spring 3 and binder block 4, and binder block 4 is slidingly matched with binder guide pad 2; The middle part of described die shoe 6 is installed with die 13; The both sides of die 13 all are installed with sliding block guide holder 14, protective cover 16 successively; Described sliding block guide holder 14 be hard-wired, about two of die shoe 6 front and back symmetries, be slidingly fitted with sliding block 9 between it, described sliding block 9 the inners are fixedly connected with volume boss mould 11; The outer end connects back-moving spring 7, and described back-moving spring 7 is fixedly installed in the described protective cover 16.

The both sides of die 13 are installed with punch guide pad 12, and punch guide pad 12 middle parts are provided with through hole, and described volume boss mould 11 passes this through hole, is slidingly matched with it.

Be installed with slide block backing plate 10 between sliding block 9 and the die shoe 6, on die shoe 6, described sliding block 9 slides on described slide block backing plate 10.

Have the fixed guide groove on the die 13, workpiece portion placed within, and described volume boss mould 11 is along its slip.

When mould is not worked, the outer end of sliding block 9, be positioned at and be installed with baffle plate 8 on the die shoe 6, this baffle plate 8 contacts described upper and

lower slide block

5,6 simultaneously.

The present invention realizes in the following manner:

Upper bolster 5 presses down, elastic binder block 4 workpiece pressings, and top shoe 1 promotion sliding block 9 moves simultaneously; Volume boss mould 11 is slided push Workpiece shaping; Upper bolster 5 is return initial position then, and back-moving spring 7 is taken back initial position with sliding block 9 simultaneously, and this initial position is by baffle plate 8 restrictions.

Baffle plate 8 when playing the position of restriction sliding block 9, position non-migration in the time of can also guaranteeing that top shoe 1 glides; The use of punch guide pad 12 can be fixed the sliding trace of volume boss mould 11, makes it stable and slides.
