Abstract
The utility model discloses a novel core pulling mould, comprising a supporting plate, wherein a cavity die is arranged on the supporting plate, an inner core pulling assembly and an outer core pulling assembly are arranged in the cavity die, the inner core pulling assembly is composed of three small core pulling slide blocks, the outer core pulling assembly is composed of three large core pulling slide blocks, and core pulling chutes are formed in the bottom of the cavity die and are respectively matched with corresponding core pulling slide blocks to realize core pulling work. The core pulling structure disclosed by the utility model replaces an existing sand core casting product to avoid the pollution phenomenon in the sand core casting process and reduce the cost; the interior of a casting formed by the inner and outer core pulling assemblies of the novel core pulling mould disclosed by the utility model is smooth and is free of sand hole, and meanwhile, no subsequent sand core cleaning work is carried out after the casting procedure; and the core pulling work is automatically finished, so that the production efficiency is greatly improved.
Description
Technical field
The utility model discloses a kind of core-pulling die, by International Patent Classification (IPC) (IPC), divides and belongs to casting mould technical field.
Background technology
Sulfur hexafluoride SF
6be a kind of dielectric, dielectric strength is 2.33 times of air, and arc extinguishing ability is 100 times of air, so be generally used for electrical equipment as insulation and/or arc-extinguishing medium, when its mounting flange is produced, be generally at present with the mould molding that increases core, there is following deficiency:
When 1, product is cast, pollute very large;
2, there is the easy drop of cast article of core, cause the inner sand holes of foundry goods;
While 3, causing increasing founder because of placement core, affect production efficiency;
4, because of core, be the running stores of foundry goods, product cost increases consumption;
5, because foundry goods is placed the operation that core causes follow-up increase cleaning core.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of novel core-pulling die, and its pulled core structure replaces existing core, and energy-conserving and environment-protective improve production efficiency simultaneously.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of novel core-pulling die, comprise gripper shoe, this gripper shoe is provided with swaging die, in swaging die, be provided with inner core pulling assembly and the assembly of loosing core outward, described inner core pulling assembly is comprised of three small slide blocks of loosing core, the assembly of loosing core is outward comprised of three large slide blocks of loosing core, and swaging die bottom is provided with looses core chute and realizes with corresponding core-pulling slide block cooperation the operation of loosing core respectively.
Further, the center of described swaging die is provided with limited block to coordinate location with inner core pulling chunk, and limited block is positioned at the chute meet of loosing core that three small slide blocks of loosing core coordinate, and in above-mentioned three chutes of loosing core, the angle of adjacent chute is 120 degree.
Further, described swaging die one side is provided with ，Gai sprue gate, sprue gate and communicates with mold cavity.
The pulled core structure that the utility model is established replaces present core cast article, when wherein inner core pulling assembly is loosed core, form circulus, loose core outward and when assembly is loosed core, be positioned at outside inner core pulling chunk and surround circulus, compare with existing core mold, there is following beneficial effect:
1, the utility model operation of loosing core, automation completes, and production efficiency significantly improves;
Contamination phenomenon while 2, avoiding core casting, once drops into Design of Dies, can repeatedly use, and integrated cost reduces;
3, the foundry goods interior smooth of the inside and outside assembly forming of loosing core of the utility model, without sand holes, simultaneously foundry goods does not have the operation of follow-up cleaning core.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Fig. 2 is another schematic diagram of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Embodiment: refer to Fig. 1 and Fig. 2, a kind of novel core-pulling die, comprise gripper shoe 1, this gripper shoe is provided with swaging die 2, in swaging die, be provided with inner core pulling assembly 3 and the assembly 4 of loosing core outward, described inner core pulling assembly 3 is comprised of three small slide blocks 31,32,33 of loosing core, and the assembly 4 of loosing core is outward comprised of three large slide blocks 41,42,43 of loosing core, and swaging die 2 bottoms are provided with looses core chute 300,400 and realizes with corresponding core-pulling slide block cooperation the operation of loosing core respectively.Swaging die of the present utility model center is provided with limited block 5 to coordinate location with inner core pulling chunk, and limited block 5 is positioned at the chute meet of loosing core that three small slide blocks of loosing core coordinate, and in above-mentioned three chutes of loosing core, the angle of adjacent chute is 120 degree.In swaging die one side, be provided with sprue gate 6, this sprue gate communicates with mold cavity.
The pulled core structure that the utility model is established replaces present core cast article, and contamination phenomenon while avoiding core casting, once drops into Design of Dies, can repeatedly use, and integrated cost reduces; The foundry goods interior smooth of the inside and outside assembly forming of loosing core of the utility model, without sand holes, simultaneously foundry goods does not have the operation of follow-up cleaning core; The operation automation of loosing core completes, and production efficiency significantly improves.
Above record, only, for utilizing the embodiment of this origination techniques content, modification, variation that any those skilled in the art use this creation to do, all belong to the scope of the claims that this creation is advocated, and be not limited to those disclosed embodiments.
