Abstract

The utility model discloses a die casting die structure, which is applied to a tubular die casting. The die structure at least comprises a movable die and a fixed die, wherein the die assembly position of the movable die and the fixed die is positioned at the pipe orifice of the tubular die casting. Preferably, the movable die is provided with a projecting post; and the projecting post is matched with the pipe orifice of the tubular die casting. By the die casting die structure, the inner diameter of the tubular die casting is formed by the projecting post, a flash is produced at the pipe orifice where the movable die is assembled with the fixed die and can be removed by grinding with abrasive paper, machining can be eliminated, and the cost is lowered.

Description

The die casting mould structure

Technical field

The utility model relates to mould applications, relates in particular to a kind of die casting mould structure.

Background technology

The metal die casting is big because of density, and can improve product weight well, becomes the requisite workpiece of modern industry.But along with each country carries out strict environmental protection standard in succession, lead element is forbidden by strictness in the various examinations and test of products.Foundry processing enterprises as the metal die casting, if the metal die casting is carried out machining, the chip of metal can be mixed into cooling machine oil in process so, thereby make whole machining system be polluted by lead element, when processing other parts next time, lead element will pollute the workpiece of other alloy, causes other products defective in by environment monitoring.Figure 1A and Figure 1B are the traditional mould structure schematic diagrames of prior art one tubulose die casting, and the structural design of cover half 1, dynamic model 2 and row position 5 as shown in the figure.Cover half 1 and dynamic model 2 can stay spue line 4 at tube wall surface like this at the tube wall place of tubulose die casting 3 matched moulds, can stay burr at the metal tube wall surface in the process of die casting, in order to remove the burr of this part, just must carry out machining.For this reason, metal is carried out machining often needs fixing a certain plant equipment, can reduce the utilization rate of board so on the one hand the free time, on the other hand can be because the restricted number of board reduces the production rate in busy.In order to address this problem, the enterprise that often produces the metal die casting can produce in specialization, can increase the metal die casting like this and get production cost.

In summary, existing tubulose die casting mould obviously exists inconvenience and defective, so be necessary to be improved on reality is used.

The utility model content

At above-mentioned defective, the purpose of this utility model is to provide a kind of die casting mould structure, and it can exempt the step of utilizing machining removal tubulose metal tube wall surface burr, reduces cost, and enhances productivity.

To achieve these goals, the utility model provides a kind of die casting mould structure, is applied to the tubulose die casting, and described mould structure comprises dynamic model and cover half at least, and the matched moulds position of described dynamic model and cover half is positioned at the mouth of pipe place of described tubulose die casting.

According to die casting mould structure of the present utility model, described dynamic model has projection, the internal diameter coupling of described projection external diameter and described tubulose die casting.

According to die casting mould structure of the present utility model, described die casting mould structure comprises the delegation position, and described dynamic model is run through in described row position, and the internal diameter coupling of the external diameter of described row position and described tubulose die casting.

According to die casting mould structure of the present utility model, described tubulose die casting is a metal tubulose die casting.

The utility model is by the matched moulds position of dynamic model and cover half in the change tubulose die casting mould, make the tubulose die casting can remove peak very easily, concrete by changing the structure of dynamic model and cover half, make the two matched moulds position when matched moulds just be positioned at the mouth of pipe place of tubulose die casting, simultaneously, need only just can remove with sand papering, needn't carry out additional machining at the peak at mouth of pipe place, save cost, enhance productivity.

Description of drawings

Figure 1A is the plan structure schematic diagram of the die casting mould of an embodiment of the prior art;

Figure 1B is the side-looking structural representation of the die casting mould of an embodiment of the prior art;

Fig. 2 is the structural representation of an embodiment of die casting mould of the present utility model;

Fig. 3 is the structural representation of another embodiment of die casting mould of the present utility model.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

See also structural representation of the present utility model shown in Figure 2, this die casting mould is mainly used in the tubulose die casting 3 of metal, it comprises cover half 1 and dynamic model 2 at least, and the mouth of pipe of the land area of cover half 1 and dynamic model 2 and tubulose die casting 3 is in same plane, shown in spue line shown in Figure 24.Dynamic model 2 has a projection 21, and the internal diameter of the external diameter of this projection 21 and tubulose die casting 3 is complementary, and in should implementing, the inwall of tubulose die casting 3 generates by projection 21.By the tubulose die casting 3 that this die casting mould structure manufacturing generates, the peak of its generation is positioned at mouth of pipe place, therefore, only needs can remove peak easily with sand papering, and need not additional machining.

Structure chart referring to another embodiment of the present utility model shown in Figure 3, in the present embodiment, tubulose die casting mould structure comprises cover half 1, dynamic model 2 and row position 5, the matched moulds position of cover half 1 and dynamic model 2 is identical with previous embodiment, be positioned at the mouth of pipe place of metal tubulose die casting 3, spue line 4 as shown in the figure.Simultaneously, dynamic model 2 is run through in row position 5, and the internal diameter coupling of the external diameter of row position 5 and tubulose die casting 3, in the practical application, can generate the inwall of tubulose die casting 3 by this row position 5, simultaneously peak also only generates at the mouth of pipe place of tubulose die casting 3, detach row position 5 and dynamic model 2 after, only need polish and can remove peak with the sand paper line up.

In sum, the utility model is by the matched moulds position of dynamic model and cover half in the change tubulose die casting mould, make the tubulose die casting can remove peak very easily, specifically be by changing the structure of dynamic model and cover half, make the two matched moulds position when matched moulds just be positioned at the mouth of pipe place of tubulose die casting, simultaneously, peak at mouth of pipe place only needs just can remove with sand papering, needn't carry out additional machining, save cost, enhance productivity.

Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
