Description

A kind of four cylinder crankshaft forging molding moulds

Technical field

It the utility model is related to crankshaft forging technical field, more particularly to a kind of four cylinder crankshaft forging molding moulds.

Background technology

Recently as the fast development of automobile making, the demand of crankshaft forging blank is rising year by year, along with China's economic Rapid development, three rise shelves passenger car diesel extensive markets.The forging for carrying out this bent axle has for capturing market Important meaning.

Because forging is smaller, routinely single-piece is forged, and existing ton forging equipment tonnage can be caused to seem superfluous, Cause cost to sharply increase, how to overcome the above difficult, solved needed for the such bent axle of exploitation produces in ton forging equipment Certainly the problem of.

Utility model content

Technical problem to be solved in the utility model is to provide one kind and is favorably improved production efficiency, effectively reduces production Four cylinder crankshaft forging molding moulds of cost.

In order to solve the above technical problems, the technical solution of the utility model is：A kind of four cylinder crankshaft forging molding moulds, bag The upper half die body and lower half die body for coordinating spiral-lock to use are included, two songs are arranged with the upper half die body and the female die body Spindle-type chamber, the profile of the bent axle die cavity are corresponding to the outline of four cylinder crankshafts.

As preferable technical scheme, the two bent axle die cavity connections are set.

As preferable technical scheme, the two bent axle die cavities are arranged at intervals.

As the improvement to above-mentioned technical proposal, the upper half die body is arranged with the both sides of the two bent axle die cavities Positioning hole, the lower half die body are arranged with lower Positioning holes in the both sides of the two bent axle die cavities, the upper Positioning holes with it is described Lower Positioning holes are correspondingly arranged up and down.

By adopting the above-described technical solution, a kind of four cylinder crankshaft forging molding moulds, including to coordinate spiral-lock to use upper Two bent axle die cavities, the crankshaft are arranged with half die body and lower half die body, the upper half die body and the female die body The profile of chamber is corresponding to the outline of four cylinder crankshafts；The beneficial effects of the utility model are：In upper half die body and lower half die body Under cooperation, the FMT of a mould two pieces can be finally realized, i.e., can once be molded two pieces crankshaft forging using one set of die, The production space of equipment has been expanded, has improved production efficiency, has significantly reduced production cost, has realized and is existed with less cost Carry out producing the task of small-sized forging on large tonnage pressing machine.

Brief description of the drawings

The following drawings is only intended to, in doing the utility model schematic illustration and explanation, not limit model of the present utility model Enclose.Wherein：

Fig. 1 is the structural representation of the utility model embodiment；

In figure：1- upper half die bodys；2- lower half die bodys；3- bent axle die cavities；4- upper Positioning holes；5- lower Positioning holes；The cylinders of 6- tetra- are bent Axle.

Embodiment

With reference to the accompanying drawings and examples, the utility model is expanded on further.In the following detailed description, only pass through Bright mode describes some one exemplary embodiments of the present utility model.Undoubtedly, one of ordinary skill in the art can be with Recognize, can be with a variety of modes to described in the case of without departing from spirit and scope of the present utility model Embodiment is modified.Therefore, accompanying drawing and description are inherently illustrative, rather than for limiting the protection of claim Scope.

As shown in figure 1, a kind of four cylinder crankshaft forging molding moulds, including coordinate upper half die body 1 and lower half that spiral-lock uses Two bent axle die cavities 3, the profile of the bent axle die cavity 3 are arranged with die body 2, the upper half die body 1 and the lower half die body 2 Corresponding to the outline of four cylinder crankshafts 6, the two bent axle die cavities 3 can connect setting, and the two bent axle die cavities 3 can also be spaced Set.When the two bent axle die cavities 3 can connect setting, a small amount of gold can be connected between the two pieces crankshaft forging part of formation Category, at this moment needs to be cut off by corresponding equipment, to facilitate follow-up trimming, correcting process to be smoothed out.

Upper half die body 1 described in the present embodiment is arranged with upper Positioning holes 4 in the both sides of the two bent axle die cavities 3, under described Half die body 2 is arranged with lower Positioning holes 5, the upper Positioning holes 4 and the lower Positioning holes 5 in the both sides of the two bent axle die cavities 3 It is correspondingly arranged up and down, by the cooperation of the upper Positioning holes 4 and the lower Positioning holes 5, whole mould can be fixed to big ton Position forcing press, realizes the production that small-sized forging is carried out using large tonnage pressing machine, and it is small dedicated for forging to avoid extra setting The small tonnage presses machine of forging, so as to reduce the usage amount of equipment, reduces the production cost of enterprise.

The utility model can finally realize the forging skill of a mould two pieces under the cooperation of upper half die body and lower half die body Art, i.e., two pieces crankshaft forging can be once molded using one set of die, expand the production space of equipment, improve production effect Rate, production cost is significantly reduced, realize with less cost and to carry out producing small-sized forging on large tonnage pressing machine Task.

The advantages of general principle of the present utility model, principal character and the utility model has been shown and described above.One's own profession The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model Claimed scope is by appended claims and its equivalent thereof.
