Abstract
The utility model provides a casting die of an engine connecting pipe. The casting die comprises an upper plate, a lower plate and an inner core, wherein, core grooves are symmetrically formed on the upper plate and the lower plate; positioning holes and convex blocks positioned on the edge of the upper plate are further arranged on the upper plate; positioning pins and concave grooves are correspondingly formed on the lower plate; and an inner core is put into an integral core groove formed when the upper plate is combined with the lower plate. When the casting die is used, the inner core is put into the core groove of the lower plate; support shafts at the two ends of the inner core falls into the two ends of the core groove; retaining sheets on the inner core fall into corresponding retaining sheet grooves at the two ends of the core groove; and then the upper plate is combined with the lower plate through the positioning pins and the positioning holes. The casting die of the engine connecting pip has a simple structure and is convenient to operate; and by utilizing the positioning holes, the positioning pins, and the convex blocks and the concave grooves which are mutually matched, high positioning accuracy is guaranteed.
Description
Technical field
The utility model belongs to mould applications, relates in particular to a kind of engine tube connector casting mould.
Background technology
In order to increase the bulk strength of engine tube, strengthen its resistivity to the effect of expanding with heat and contract with cold, on the outer wall of engine tube connector, be provided with circular ripple.Because the tube connector that has ripple is much more complicated than the tube connector of ordinary construction, it has proposed new requirement to the precision of casting mould and the convenience of operation.
The utility model content
The purpose of the utility model provides a kind of simple to operate, engine tube connector casting mould that positional accuracy is good.
The technical scheme of the utility model is: engine tube connector casting mould comprises upper plate, lower plate and inner core.Also be provided with locating hole on the upper plate and be positioned at the projection at edge, correspondingly be provided with alignment pin and groove on the lower plate, the two ends of said inner core are provided with bolster, and middle surface is provided with circular ripple.
Further, also be provided with circular catch on the bolster at said inner core two ends.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, this engine tube connector casting mould is simple to operate, and locating hole, alignment pin and the projection that matches and groove have guaranteed very high positional accuracy.
Description of drawings

Fig. 2 is the lower plate structural front view of the utility model engine tube connector casting mould;
Fig. 3 is the core arrangement sketch map of the utility model engine tube connector casting mould.
Among the figure:
1, upper plate 2, core groove 3, locating hole
4, projection 5, alignment pin 6, groove
7, inner core 8, lower plate 71, ripple
72, catch 73, back shaft
The specific embodiment
Engine tube connector casting mould shown in Fig. 1 to 3 comprises upper plate 1, lower plate 8 and inner core 7.Also be provided with locating hole 3 on the upper plate 1 and be positioned at the projection 4 at edge, correspondingly be provided with alignment pin 5 and groove 6 on the lower plate 8, the two ends of said inner core 7 are provided with bolster 73, and middle surface is provided with circular ripple 71.
In the present embodiment, also be provided with circular catch 72 on the bolster 73 at said inner core 7 two ends.
The course of work of this instance: during use, in the core groove 2 of lower plate 8, lay a certain amount of sheet rubber, inner core 7 is placed on these sheet rubbers again, the position aligns with following core groove 2 substantially.On inner core 7, lay sheet rubber afterwards, be combined in upper plate 1 on the lower plate 8 through alignment pin 5 and locating hole 3 again.Entire die is put into extrusion equipment, and jacking mechanism presses together upper plate 1 and lower plate 8, and inner sheet rubber melts under huge extruding force.After a period of time, take out mould, raise upper plate 1, take out inner core 7, the tube connector that casting this moment is good is enclosed within on the inner core 7, when its temperature is also higher, utilizes high pressure air rifle that tube connector is blown down.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
