Abstract

The utility model discloses a cover body machining die and relates to an open cover blank formed through blanking, stretching and rotating cutting. Especially, the cover body machining die is composed of a die seat and a die cover. A male die block matched with an inner cavity of the open cover blank is slidably connected to the die seat, a female die groove matched with the open cover blank is slidably connected to the die cover, and the male die block and the female die groove form a die cavity for loading the open cover blank; when the die seat and the die cover are in a closed-die state, the bottom of the male die abuts against the die seat, and the blank wall, located on the open cover blank, of the die cavity is provided with an annular clamping seam. Due to the cover body machining die, the clamping seams are reserved between the die seat and the die cover, gaps exist between the male die block and the open cover blank, the die seat and the die cover are in butt-joint punching relation with each other, and therefore the open cover blank abuts against the male die block under the action of the female groove die; because the blank wall of the open cover blank overflows along the clamping seams to form an annular rib, integral forming is fast and convenient, operation is easy and cost is low.

Description

A kind of processing mold of lid

Technical field

The utility model relates to a kind of processing mold of lid, relates in particular to a kind of processing mold that is provided with ring rib lid.

Background technology

In people's daily life, can relate to the use of lid, and the processing mode of lid is also varied, and in agricultural vehicle production process, can relates to a kind of fuel tank cap, fuel tank cap adopts mould to carry out after production and processing conventionally, then puts in agricultural vehicle production.

Cover structure for fuel tank is comparatively simple and easy, usually adopts easy uncovered fuel tank cap, and easy uncovered fuel tank cap easily causes between fuel tank and fuel tank cap producing space, and the situation of fuel oil volatilization occurs, and causes unnecessary economic loss.Prior art designs in original easy fuel tank cap, and fuel tank cap is provided with ring rib, mates with fuel tank by ring rib, can effectively prevent fuel oil volatilization, but the fuel tank cap production technology with ring rib is in the market comparatively complicated, and cost is higher.

Utility model content

In view of the defect that above-mentioned prior art exists, the purpose of this utility model is to propose a kind of processing mold that is provided with ring rib lid.

The purpose of this utility model, to be achieved by the following technical programs: a kind of processing mold of lid, relate to through blanking, the uncovered lid base of stretching and rotary-cut moulding, especially, described lid mould is made up of die holder and die cap, described die holder slips the convex module matching with the inner chamber of uncovered lid base, described die cap slips and is provided with the die groove matching with uncovered lid base, described convex module and die groove form the die cavity that loads uncovered lid base, described die holder and die cap matched moulds state lower punch piece bottom connect with die holder, and die cavity be positioned at uncovered lid base base wall place be provided with annular crack.

Further, described die holder is provided with locating dowel, and described die cap is provided with the locating slot matching with locating dowel.

Further, described die holder and die cap are respectively equipped with excellent power glue buffer gear along mold closing direction.

Apply processing mold of the present utility model, between die holder and die cap, be reserved with crack, and there is gap between convex module and uncovered lid base, by the docking punching press of die holder and die cap, uncovered lid base docks with convex module under the effect of chase form, and the base wall of uncovered lid base overflows moulding formation ring rib along crack, one-body molded efficient and convenient, simple to operate, with low cost.

Brief description of the drawings

Fig. 1 is the structural representation of the processing mold of a kind of lid of the utility model.

Fig. 2 is the structural representation of the processing mold matched moulds state of a kind of lid of the utility model.

Fig. 3 is the structural representation of uncovered lid base machine-shaping.

Detailed description of the invention

Below just accompanying drawing in conjunction with the embodiments, is described in further detail detailed description of the invention of the present utility model, so that technical solutions of the utility model are easier to understand, grasp.

As shown in Figure 1 to Figure 3, a kind of processing mold of lid, relate to the uncovered lid base 1 through blanking, stretching and rotary-cut moulding, especially, lid mould is made up of die holder 2 and die cap 3, die holder 2 slips the convex module 4 matching with the inner chamber of uncovered lid base 1, die cap 3 slips and is provided with the die groove 5 matching with uncovered lid base 1, convex module 4 forms with die groove 5 die cavity 6 that loads uncovered lid base 1, die holder 2 connects with die cap 3 matched moulds state lower punch piece 4 bottoms and die holder 2, and die cavity 6 be positioned at uncovered lid base 1 base wall place be provided with annular crack 7.

Wherein, die holder 2 is provided with locating dowel 22, and die cap 3 is provided with the locating slot 32 matching with locating dowel 22, and locating dowel 22 matches and docks with locating slot 32, prevents that die cap 3 and die holder 2 from producing dislocation in the time of matched moulds.

In addition, die holder 2 and die cap 3 are respectively equipped with excellent power glue buffer gear 8 along mold closing direction, this excellent power glue buffer gear can prevent that processing mold from causing die holder and the inner hard collision that occurs of die cap in process, and punch die operation is cushioned, and it is round and smooth that the marmon clamp of lid is seamed into type.

When concrete enforcement, cover materials is passed through blanking, stretching and rotary-cut moulding make uncovered lid base, uncovered lid base is placed in to the convex module of die holder, die holder and die cap matched moulds, die groove supports uncovered lid base and promotes uncovered lid base pressure holding convex module, convex module slides into convex module bottom in die holder and offsets with die holder, now die holder and die cap continue matched moulds, convex module and die groove carry out punching press to uncovered lid base simultaneously, after uncovered lid base is stressed, base wall forms ring rib along the outside relaxation of annular crack, after the complete moulding of uncovered lid base, die holder and die cap parting, now uncovered lid base machines.

Visible by above description: to apply processing mold of the present utility model, between die holder and die cap, be reserved with crack, and there is gap between convex module and uncovered lid base, by the docking punching press of die holder and die cap, uncovered lid base docks with convex module under the effect of chase form, and the base wall of uncovered lid base overflows moulding formation ring rib along crack, one-body molded efficient and convenient, simple to operate, with low cost.

The utility model still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming, within all dropping on protection domain of the present utility model.
