Abstract
The utility model relates to an impeller mould fetching device and particularly relates to an impeller mould fetching and positioning block. The utility model adopts the following technical scheme: the impeller mould fetching and positioning block comprises pressure plates, a module, positioning blocks, exhaust pins, pulling blocks, pulling cores, impeller bodies and an upper mould plate, wherein the exhaust pins, the pulling blocks, the pulling cores and the impeller bodies are arranged in the upper mould plate and a lower mould plate; the impeller bodies are mounted on two sides of each pulling core; the exhaust pins are arranged in the pulling cores; the pressure plates are mounted on two sides of the upper mould plate; the module is arranged above the upper mould plate; the positioning blocks are arranged on three surfaces of a non wax filling hole of the lower mould plate below the upper mould plate. The impeller mould fetching and positioning block has the beneficial effects that (1) the positioning blocks are arranged on the three surfaces of the non wax filling hole of the impeller mould; (2) the positioning blocks are directly contacted with a fusible core of an impeller, and the length of each positioning block, extending into the fusible core, is greater than 20mm; (3) the positioning blocks are fixed on the lower mould plate of a mould by two M8 inner hexagonal screws. According to the impeller mould fetching and positioning block, the production efficiency and the product quality are improved and the labor intensity of an operation worker is reduced.
Description
Technical field
The utility model relates to a kind of impeller mold impression-taking apparatus, particularly a kind of impeller mold delivery locating piece.
Background technology
In the investment casting process, the formation of impeller channel mainly is to rely on water-soluble core or ceramic core, offers the positioning table of water-soluble core, ceramic core at mould, then by compacting, forms impeller channel.The mould of making in the past is to offer loose piece in the lower bolster centre position of mould for the ease of delivery, after the wax-pattern compacting is finished, mould is holded up, take off first loose piece, then use compressed air to blow out wax spare, perhaps use wooden stick, glue rod that wax-pattern is ejected from mold cavity.Such operation is very loaded down with trivial details, and labour intensity is large, and some are large (impeller diameter surpasses 300, mold weight surpass 50 Kg) mould needs two, three people to assist, and the mould of holding up easily topples over, and has potential safety hazard.There is distortion in the wax spare that uses compressed air, wooden stick, glue rod to take out, causes wax-pattern to use, and needs again compacting, has affected production efficiency.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of impeller mold delivery locating piece is provided, and has improved production efficiency, product quality, has reduced operative employee's labour intensity.
Its technical scheme is: comprise pressing plate, module, locating piece, exhaust pin, take out piece, loose core, impeller body and cope match-plate pattern, described cope match-plate pattern and lower bolster inside are provided with the exhaust pin, take out piece, loose core, impeller body, impeller body be installed in the both sides of loosing core, be provided with the exhaust pin in loosing core; Pressing plate is installed in both sides at cope match-plate pattern, and the cope match-plate pattern top is provided with module, and three faces of the non-casting mouth of the lower bolster below cope match-plate pattern are offered locating piece.
The above-mentioned cope match-plate pattern outside is provided with a plurality of handles.
Two soket head cap screws of above-mentioned locating piece are fixed.
The beneficial effects of the utility model are: (1) offers locating piece at three faces of the non-casting mouth of impeller mold; (2) locating piece directly contacts with the molten core segment of impeller, and stretches into molten core length greater than 20mm; (3) locating piece uses two M8 soket head cap screws to be fixed on the lower bolster of mould.The utility model has improved production efficiency, product quality, has reduced operative employee's labour intensity.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is A-A schematic diagrames of the present utility model;
Accompanying drawing 3 is B-B schematic diagrames of the present utility model;
Among the upper figure: handle 1, pressing plate 2, module 3, locating piece 4, exhaust pin 5, take out piece 6, loose core 7, impeller body 8, cope match-plate pattern 9.
The specific embodiment
1-3 by reference to the accompanying drawings, the utility model will be further described:
The utility model comprises pressing plate 2, module 3, locating piece 4, exhaust pin 5, take out piece 6, loose core 7, impeller body 8 and cope match-plate pattern 9, described cope match-plate pattern 9 and lower bolster inside is provided with exhaust pin 5, take out piece 6, loose core 7, impeller body 8, loose core 7 both sides of being installed in of impeller body 8, loosing core is provided with exhaust pin 5 in 7; Pressing plate 2 is installed in both sides at cope match-plate pattern 9, and cope match-plate pattern 9 tops are provided with module 3, and three faces of the non-casting mouth of the lower bolster below cope match-plate pattern 9 are offered locating piece 4, and the dimension width of locating piece is 50-80mm.
Wherein, cope match-plate pattern 9 outsides are provided with a plurality of handles 1, and 4 two M8 soket head cap screws of above-mentioned locating piece are fixed.
This locating piece is mainly used in adopting in the model casting molten core to form the wax-pattern compacting of impeller channel, after the compacting, utilizes locating piece wax-pattern can be taken out smoothly.Advantage is: (1) offers locating piece at three faces of the non-casting mouth of impeller mold; (2) locating piece directly contacts with the molten core segment of impeller, and stretches into molten core length greater than 20mm; (3) locating piece uses two M8 soket head cap screws to be fixed on the lower bolster of mould.
In the Mold Making stage, the size and structure of locating piece is set after, made by the mould factory, after the mould acceptance(check), carry out the compacting of wax-pattern.After opening upper mould, at first locating piece is taken out, then place the molten core of impeller, the rear locating piece of placement resets and locks, the compacting of beginning wax-pattern.After the wax-pattern compacting, at first open patrix, then use pneumatic impact spanner or spanner that locating piece is unclamped, extract locating piece out, stretch into the locating piece original position with hand, catch molten core to take out wax spare.Wax spare after taking out resets locating piece, and the locking of M8 soket head cap screw can be suppressed behind the matched moulds again.
