Abstract

The utility model discloses a model core for U shape pipe fittings, which is composed of a plurality of core ring chips as equal 180 degrees along an extension direction of the U shape pipe fittings. The core ring chip is divided into two chips, arranged symmetrically along two sides of syncopate of a U shape pipe. Guide channels are arranged in a plurality of core ring chips, a chain is arranged in the guide channel and the chain is connected with the core ring chip. When the U shape fitting is produced, the core ring chip is driven by the chain arranged along the two sides of A-A syncopate of the U shape pipe for the movement along the guide channel so as to complete conjunction at A-A section of the core ring chip at the U shape pipe syncopate. Due to the symmetrical core ring chip structure at two sides of the A-A section of the U shape pipe, automatic mold unloading of the core is realized to work out the U shape pipe fitting without a dead angle, improving production efficiency of the U pipe fitting, saving production procedure and reducing production cost.

Description

The core of U type pipe fitting production moulding

Technical field

The utility model relates to pipe fitting and makes the field, the core that is adopted when especially referring to a kind of U type pipe fitting production moulding.

Background technology

U type pipe fitting is because two port of export turns to through 180 degree, and therefore, used core is difficult to the disposable demoulding of loosing core and finishes during production, needs to make through multiple working procedure, thereby has increased production cost, has also increased difficulty for the design and use mould; Disclose a kind of " U type pipe fitting injecting molding die " as Chinese patent ZL99237880, its mold cores is divided into two parts symmetrical, and every part is divided into straight core and circular arc core again, and the circular arc type core segment adopts flexible controlled connection, makes it to be the corner mode and extracts out; Because the core of this U type pipe fitting mold does not possess symmetry, the U type pipe of producing has because of straight core and the butt joint of circular arc core, the dead angle of back because of intersection formation of loosing core, both influenced the aesthetic feeling of product appearance, again transmission medium is produced retardation, therefore must improve the related core of above-mentioned production U type pipe fitting on this basis.

Technical scheme

The purpose of this utility model provides a kind of core of U type pipe fitting production moulding, the slick and sly no dead angle of the U type pipe fitting tube wall that utilizes this core to produce.

The technical solution of the utility model is achieved in that

A kind of core of U type pipe fitting production moulding is provided, it is characterized in that: described core is cooperatively interacted by a plurality of core ring plates that are five equilibrium 180 degree angles along U type pipe fitting bearing of trend and forms.

The core of aforesaid U type pipe fitting production moulding is characterized in that: described a plurality of core ring plates are divided into two, and are provided with along U type pipe cutting face bilateral symmetry.

The core of aforesaid U type pipe fitting production moulding is characterized in that: be provided with gathering sill in described a plurality of core ring plates, be provided with chain in the gathering sill, chain is connected with the core ring plate.When producing U type pipe fitting, the chain that is provided with along U type pipe cutting face both sides drives the core ring plate and moves along gathering sill, make the core ring plate dock at U type pipe cutting face place, behind the U type pipe fitting moulding by casting, when loosing core, chain is extracted the core ring plate along gathering sill and is separately shape, take out U type pipe fitting from mould after, repeat said process again and get final product.

Core through the U of above setting type pipe fitting production moulding, because of having adopted the structure that the core ring plate is set along U type pipe cutting face bilateral symmetry, realized the automatic demoulding of core, and the slick and sly no dead angle of the U type pipe fitting tube wall of producing, both improved the production efficiency when producing U type pipe fitting, save production process, reduced production cost again.

Description of drawings

The fractal line of B-B is the plane structure chart of core described in the utility model with top among Fig. 1; The whole figure of Fig. 1 is to utilize the utility model to produce the plane structure chart of U type pipe fitting.

Fig. 2 is that Fig. 1 is applied in the structural plan figure on the mould, and this mould is that a mould four goes out when producing U type pipe fitting.

Fig. 3 is the structure enlarged drawing of the circle part of mark C among Fig. 2.

Fig. 4 is the profile that utilizes a kind of U type pipe fitting of mould production shown in Figure 2.

Fig. 5 is the three-dimensional structure diagram that utilizes a kind of U type pipe fitting of mould production shown in Figure 2.

Embodiment

Below in conjunction with description of drawings embodiment of the present utility model:

Referring to Fig. 1 to Fig. 5, a kind of core of U type pipe fitting production moulding is provided, described core is cooperatively interacted by a plurality of core ring plates 1 that are five equilibrium 180 degree angles along U type pipe fitting bearing of trend and forms; Above-mentioned a plurality of core ring plates are divided into two, are provided with along U type pipe cutting face A--A bilateral symmetry.Be provided with gathering sill 2 in described a plurality of core ring plate 1, be provided with chain 3 in the gathering sill 2, chain 3 is connected with core ring plate 3.

When producing U type pipe fitting, the chain 3 that is provided with along U type pipe cutting face A--A both sides drives core ring plate 1 and moves along gathering sill 2, make core ring plate 1 dock at U type pipe cutting face A--A place, behind the U type pipe fitting moulding by casting, when loosing core, chain 3 is extracted core ring plate 1 along gathering sill 2 and is separately shape, take out U type pipe fitting from mould after, repeat said process again and get final product.

Be set to 8 as core number in the utility model, then core ring plate 1 number of cutting face A--A both sides setting is 4; The rest may be inferred can draw various embodiments.

The structure that the number, gathering sill of core ring plate 1 is set and transmits the chain of core ring plate 1 along cutting face A--A bilateral symmetry in the utility model is the emphasis of the utility model; draw the core of U type pipe fitting production moulding according to this, all fall into protection domain of the present utility model with said structure.
