Description

A kind of cement type surface simple drawing mold structure

Technical field

The utility model belongs to technical field of mold, is specifically related to a kind of drawing die structure.

Background technology

The simple and easy drawing die of automobile panel is mainly simple and easy steel mould, low-melting-point alloy die and epoxy resin mould at present.Low-melting-point alloy die material price height, near 10,000 yuan/ton, and the mould manufacturer need have special low-melting alloy Casting Equipment, and its cost of equipment input is huger.The epoxy resin mould material price is a little less than 10,000 yuan/ton, and is also quite expensive, and it also needs digital control processing obtaining die face after the combination on the steelframe.Simple and easy steel mould material price is cheap, be lower than low-melting-point alloy die half, but its profile process velocity is slow, expense is not low.

Simple and easy drawing die is mainly used to produce the covering exemplar, and its die life is less demanding, so manufacturing cycle and cost need lowly as far as possible, therefore develops the simple and easy drawing die that a kind of Master Cost is low, processing is cheap and is worth obviously.

Summary of the invention

The purpose of this utility model is at deficiencies such as existing simple drawing mold Master Cost height, processed complexs, and the simple drawing mold that a kind of Master Cost is low, processing is cheap is provided.

The technical solution of the utility model is as follows:

A kind of cement type surface simple drawing mold structure, it includes counterdie, to mould pin, blank holder, patrix, cement type surface hold-down bars, patrix lining, cement type surface.Described blank holder, counterdie are the structure of steel die of simple die, and profile is a steel type face, is formed by digital control processing.Patrix is a structure of steel die, and profile is a cement type surface, and the patrix lining is arranged in the cement type surface, is embedded in the patrix cement type surface in the cement grouting process, and at the correspondence position of counterdie the profile hole is set, and tight fit has counterdie to the mould pin in the profile hole.

Described cement type surface is to be fixed on the patrix by the cement type surface hold-down bars of casting on the patrix, is provided with the cement grouting mouth in the patrix bottom, and patrix die joint place is provided with the cement grouting steam vent.

The utility model is compared with existing low-melting-point alloy die, epoxy resin mould and clean steel plate simple die, has following tangible advantage: need not process the patrix profile, save material and digital control processing expense; Cement type surface is made simple, cost is low, the process-cycle weak point can directly be enhanced productivity, and this mould can be applied to during workshop exemplar drawing die makes the medium-sized part as the complex-shaped degree such as front-wheel bulge in the automobile panel, engine bin side plate of drawing that can safety.

Description of drawings

Fig. 1 is the structural representation after the mould closure;

Fig. 2 is the patrix structural representation with cement type surface.

The specific embodiment

Referring to Fig. 1 and Fig. 2, this cement type surface simple drawing mold is made up of mould pin 6 and counterdie 7 patrix 1, the cement type surface hold-down bars 2 that is cast in patrix, patrix lining 3, cement type surface 4, blank holder 5, counterdie.Cement type surface 4 is fixed on the patrix 1 by the cement type surface hold-down bars 2 of patrix 1, and cement type surface hold-down bars 2 is cast on the patrix 1, and patrix lining 3 is embedded in the patrix cement type surface 4 in the cement grouting process, and counterdie fits tightly in the profile hole 10 of counterdie 7 mould pin 6.Cement type surface 4 has perfusion to use steam vent at patrix die joint place, in the patrix bottom surface cement grouting mouth 8 is arranged.The counterdie that the descending blank holder 5 that compresses during patrix 1 work, patrix lining 3 align counterdie 7 to mould pin 6 after, mold work cooperates and puts in place.Need to prove that the part forming process is: before drawing, plate places on the blank holder 5, and patrix 1 is descending in the drawing process, and is descending with blank holder 5 after blank holder 5 compresses plate, on counterdie 7, by pressure with operation part draw forming.

Cement type surface 4 processing modes of patrix are as follows: elder generation is at the wax disk(-sc) of the following thick degree of die-cushion drawn component material, after will not having profile patrix and counterdie matched moulds, by the patrix sprue gate to the patrix cement injection, cement relies on patrix cemented rod fixing, and the patrix lining is placed in counterdie on the mould pin when matched moulds, pour back bush and be fixed in the patrix cement type surface, after waiting to the cement solidifies, the patrix profile machines, and the machine of need not adds and bedding-in, and shorten process time.Cement adopts No. 60 cement, adds a small amount of river sand, glue, metal dust.

Claims (3)

1. a cement type surface simple drawing mold structure includes patrix (1), blank holder (5) and counterdie (7), and described blank holder (5), counterdie (7) are structure of steel die, and profile is a steel type face; It is characterized in that: patrix (1) is a structure of steel die, and profile is cement type surface (4), and patrix lining (3) is arranged in the cement type surface (4), and by profile hole (1), tight fit has counterdie to mould pin (6) in profile hole (1) at the correspondence position of counterdie (7).
