Abstract

The utility model discloses a mold core structure convenient for clearing a product left in a mold cavity, and the structure comprises a mold body with the cavity; a plurality of mold cores are arranged in the cavity; the structure is characterized in that at least one mold core is detachable; and the mold cores are arranged in through holes of the mold body in a matched way, and can be detached from the through hole on the back surface of the cavity. The mold core structure convenient for clearing the product left in the mold cavity has the advantages that because the detachable mold core is arranged on the mold body, when the product is left in the cavity of the mold body, the product which is left in the cavity can be jacked out by taking out the mold core from the through hole by a tool, then inserting the tool into the through hole, jacking the left product and finally knocking the tool which jacks the product by a hammer; only little change needs to be carried out based on the original mold, and the improving cost is low; and more mold cores can be set as required, so that the left product can be cleared more thoroughly.

Description

Be convenient to clear up the core structure that remains in product in the mold cavity

Technical field

The utility model relates to a kind of mould, particularly is convenient to clear up the core structure that remains in product in the mold cavity.

Background technology

Traditional compression mod mainly is made up of dynamic model and cover half, is provided with ejecting mechanism in dynamic model.The general comparatively mould of complicated product all can arrange core, and described core protrudes the lower surface of mold cavity, forms groove or cavity on the product.When die-cast product, cover half is fixed on the die casting machine cover half installing plate, dynamic model is fixed on the die casting machine dynamic model installing plate.During matched moulds, fixed half and moving half is closed formation die cavity and casting system under the drive of die casting machine, and liquid metals under high pressure is full of die cavity; When die sinking, entire product intactly is attached on the dynamic model, by the dynamic model ejecting mechanism product is ejected.Yet, because some product mould shape more complicated, often occur in process of production portioned product break on cover half and/or dynamic model can't complete taking-up situation, thereby influence reusing of mould.Therefore, in the time of in portioned product remains in mould, need residual product is taken out in mould, in order to reuse mould.

At present, taking off the product that remains in the mould realizes by the following method: at first, the mould that will have bottom product is pulled down from the installing plate of die casting machine; Then, mould pincers worker recruitment tool is bit by bit broken bottom product into pieces, at last fragment is taken out.Adopt this method more time-consuming, need cost three to five hours usually, in addition longer, simultaneously, because power is difficult to grasp, also mould can be damaged sometimes.After mould damages, need usually just can resume production after several days, influence manufacturing schedule, cause the phenomenon that lags behind delivery date, diminish company reputation.

The utility model content

The purpose of this utility model be provide in order to solve above-mentioned the deficiencies in the prior art a kind of simple and reasonable, the cleaning bottom product be convenient to clear up the core structure that remains in product in the mold cavity fast.

To achieve these goals, the utility model is designed is convenient to clear up the core structure that remains in product in the mold cavity, comprise the die ontology that has die cavity, in die cavity, be provided with several cores, it is characterized in that, described core has at least one to be detachable setting, and the core cooperation is installed in the through hole of die ontology, can dismantle in the described through hole in the back side of die cavity.

Place core in the through hole for the ease of taking-up, described core is fixed in the die ontology by screw, is provided with the internal thread that matches with screw at core.

Place core in the through hole for the ease of taking-up, described core is fixed in the die ontology by nut, is provided with the external screw thread that matches with nut at the end of core.

The core structure that remains in product in the mold cavity of being convenient to clear up that the utility model obtains has following advantage:

1, by detachable core is set in die ontology, when residual when product is arranged in the die cavity of die ontology, only need tool using that core is taken out from through hole, and then instrument inserted in the through hole, and withstand residual product, the instrument that withstands product of hitting with a hammer at last can will remain in product in the die cavity eject.

2, mould only need be done less change on the original basis and gets final product, and it is low to improve cost.

3, can as required several cores be set, thereby it is more thorough to make that bottom product is removed more.

Description of drawings

Fig. 1 is the structural representation when core is connected with mould by screw among the embodiment;

Fig. 2 is the structural representation when core is connected with mould by nut among the embodiment;

Fig. 3 is the view of mould when matched moulds among the embodiment.

Among the figure: die ontology 1, die cavity 11, through hole 12, core 2, internal thread 21, external screw thread 22, screw 3, nut 4.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

Embodiment:

Present embodiment provides is convenient to clear up the core structure that remains in product in the mold cavity, as Fig. 1, shown in Figure 3, comprise the die ontology 1 that has die cavity 11, in die cavity 11, be provided with B1, B2, three core 2(of B3 as shown in Figure 2), described core 2 has at least one to be detachable setting, core 2 cooperations are installed in the through hole 12 of die ontology 1, can the dismounting in the described through hole 12 from the back side of die cavity 11.

As shown in Figure 1, place core 2 in the through hole 12 for the ease of taking-up, described core 2 is fixed in the die ontology 1 by screw 3, is provided with the internal thread 21 that matches with screw 3 at core 2.

Above-mentioned core 2 also has with the syndeton of die ontology 1: as shown in Figure 2, described core 2 is fixed in the die ontology 1 by nut, is provided with the external screw thread 22 that matches with nut 4 at the end of core 2; End at core 2 arranges a pin-and-hole, and with pin core 2 is fixed in the die ontology 1.

Concrete operations mode with regard to present embodiment is explained as follows below:

When part remains on the die ontology.Can be in the following way the product that remains in the die ontology 1 be taken out: at first, the employing instrument also stretches in the through hole 12, and will take out one by one for the fixing screw 3 of core 2.Then, adopt to have externally threaded instrument and stretches in the through hole 12, and screw in core 2, have externally threaded instrument and match with internal thread 21 on the core 2, so in the through hole 12 taking-up B1, B2 and B3.After taking out whole cores 2, can stretch in the through hole 12 by the employing instrument, and offset with the product that remains in the die ontology 1, adopt hammer evenly to knock the instrument that offsets with product then, take out until the product that will break on die ontology 1.

Need to prove at last, above embodiment is only in order to the technical solution of the utility model to be described but not the restriction technologies scheme, although the applicant has been described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, those are made amendment to the technical solution of the utility model or are equal to replacement, and do not break away from aim and the scope of the technical program, all should be encompassed in the middle of the claim scope of the present utility model.
