Abstract

The utility model discloses an elbow pipe evanescent molding core which is a molding core of on the inner wall of a molding elbow pipe. The elbow pipe evanescent molding core comprises a locating inner core made of plastic materials and an evanescent molding core sleeved on the outer side of the locating inner core and made of water soluble biological materials. The elbow pipe evanescent molding core has the advantages of reducing producing processes, reducing process complexity, improving producing efficiency, reducing producing cost, reducing product reject ratio, enabling a structure to be more stable, prolonging service life and being applied to elbow pipes with more complex models.

Description

A kind of bend pipe disappearance forming core
Technical field
The utility model relates to bend pipe manufacturing technology field, relates in particular to a kind of core of moulding elbow internal wall shape.
Background technology
Tradition forming elbow technology is divided into two schemes.Wherein a kind of scheme bend pipe is assembled by multi-part; Another kind of scheme bend pipe is through post forming.There is following shortcoming in tradition bend pipe manufacturing technology:
1, manufacturing process is many and complicated;
2, production efficiency is low;
3, manufacturing cost is high;
4, the product fraction defective is high;
5, the not firm product that causes of structure is short service life;
6, the bend pipe moulding is limited to.
The utility model content
The purpose of this utility model is for the problems referred to above weak point, a kind of bend pipe disappearance forming core is provided, has the minimizing production technology, reduce the complexity of technique, enhance productivity, reduce production costs, reduce the product fraction defective, make structure more firm, improve service life and the applicable more advantage of the bend pipe of complex model.
In order to achieve the above object, the utility model is by the following technical solutions:
A kind of bend pipe disappearance forming core, it is the core of moulding elbow internal wall, it comprises the location inner core of being made by plastic material and is sheathed on location inner core disappearance forming core outer, that made by water-soluble solution biomaterial.
Described location inner core is provided with a core bar, and this core bar one end connects a plush copper.
Described plush copper is spherical.
Further, described location core shape is corresponding with the disappearance forming core.
Making and the use procedure of a kind of bend pipe disappearance of the utility model forming core:
At first produce the location inner core of required profile, utilize water-soluble solution biomaterial to produce the disappearance forming core at this location inner core, finally obtain required bend pipe disappearance forming core for subsequent use.
A kind of bend pipe disappearance of the utility model forming core, the product die cavity that it cooperates upper mould and lower mould to form.Running gate system by injection machine or die casting machine is injected into material in the product die cavity, cooling is opened mould and is obtained semi-finished product, the location inner core that obtains in the semi-finished product is pulled out by the smelting tool, the semi-finished product of again this having been pulled out the location inner core disappear the dissolving of disappearance forming core by lysate, and final cleaning obtains the bend pipe finished product.
The utility model adopts said structure, has the minimizing production technology, reduces the complexity of technique, enhances productivity, and reduces production costs, and reduces the product fraction defective, makes structure more firm, improves service life and the applicable more advantage of the bend pipe of complex model.
Description of drawings
Fig. 1 is the utility model core bar schematic diagram.
Fig. 2 is the utility model core bar and disappearance forming core one schematic diagram.
Fig. 3 is the utility model production bend pipe and the cross-sectional schematic of pulling out the core bar.
Fig. 4 is the bend pipe cross-sectional schematic that the utility model has dissolved the disappearance forming core.
Fig. 5 is the bend pipe schematic perspective view that the utility model is produced.
Below come the utility model is further described by the drawings and specific embodiments.
The specific embodiment
Such as Fig. 1 to shown in Figure 5, a kind of bend pipe disappearance of the utility model forming core, it be the core of moulding elbow internal wall, it comprise the location inner core 1 of being made by plastic material and be sheathed on location inner core 1 outward, the disappearance forming core 2 made by water-soluble solution biomaterial.
Described location inner core is provided with a core bar 11, and this core bar one end connects a plush copper 12.
Described plush copper 12 is spherical.
Further, described location inner core 1 shape is corresponding with disappearance forming core 2.
Making and the use procedure of a kind of bend pipe disappearance of the utility model forming core:
At first produce the location inner core 1 of required profile, utilize water-soluble solution biomaterial to produce disappearance forming core 2 at this location inner core 1, finally obtain required bend pipe disappearance forming core for subsequent use.
A kind of bend pipe disappearance of the utility model forming core, the product die cavity that it cooperates upper mould and lower mould to form.Running gate system by injection machine or die casting machine is injected into material in the product die cavity, cooling is opened mould and is obtained semi-finished product, the location inner core 1 that obtains in the semi-finished product is pulled out by the smelting tool, the semi-finished product of again this having been pulled out location inner core 1 disappear the dissolving of disappearance forming core by lysate, and final cleaning obtains bend pipe 3 finished products.
The utility model adopts said structure, has the minimizing production technology, reduces the complexity of technique, enhances productivity, and reduces production costs, and reduces the product fraction defective, makes structure more firm, improves service life and the applicable more advantage of the bend pipe of complex model.
Above explanation and unrestricted the technical solution of the utility model, every technology that does not break away from the utility model spirit all belongs in the claim scope of the present utility model.
