Description

The bronze drum mould

Technical field

The utility model relates to a kind of mould, particularly a kind of mould of making bronze drum.

Background technology

Bronze drum is China south and some national handicrafts of Southeast Asia, and the long history in more than 2,000 year is arranged.Some minority areas of China, as the Tiane in Guangxi, Nandan, Donglan, Fengshan, crust horse, bigization, all the area such as pacify and all be unable to do without bronze drum at occasions such as festival celebration, marriage, funerals, the image of bronze drum also becomes the symbol of national culture.Along with developing rapidly of tourist industry, bronze drum also is familiar with, is understood, is liked by more people gradually, particularly as the little bronze drum of handicraft and tourist souvenir, is subjected to liking of people deeply.

At present the preparation technology of bronze drum has and adopts after the artificial beatening depiction by hand to form again, and also has and adopts the method for paraffin casting to make.Adopt artificial method for making to producer's specification requirement height, production efficiency is low, fabrication cycle is long, with high costs, product quality is difficult for guaranteeing, is difficult to satisfy the demand in market, and adopts the operation of paraffin casting method various, complicated, production efficiency is low.

The utility model content

Technical problem to be solved in the utility model provides a kind of bronze drum mould that can improve bronze drum production efficiency.

The utility model solves the problems of the technologies described above with following technical scheme: pedestal 7 is arranged at the bottom of this mould, there is circular cone stage body 10 middle part of pedestal 7, there is cover plate 1 top of circular cone stage body 10, periphery is with the cydariform core 6 that is surrounded by pellet in the several piece 12, the periphery of cydariform core 6 is with by at least two block external cavity pieces 13 are hinged and surrounds, and the cydariform exocoel 5 that is complementary with cydariform core 6, all leave the gap between cydariform core 6 and the cydariform exocoel 5 and between cydariform core 6 and circular cone stage body 10 and the cover plate 1, the top of cydariform core 6 and cydariform exocoel 5 has circular draw-in groove 14 and 15, be equipped with circular retainer 3 in the circular draw-in groove 14 of cydariform core 6, the bulge loop 4 and the plug hole 2 that can snap in circular draw-in groove 15 are arranged on the cover plate 1.

Described cydariform exocoel 5 can be made of three block external cavity pieces 13, wherein the two side ends of a block external cavity piece respectively with other two have the exocoel piece of handle 8 hinged by bearing pin 11, have between the two block external cavity pieces of handle to connect by movable pin 9.

Pattern all is carved with in the bottom surface of the inwall of described cydariform exocoel 5 and cover plate 1.

Have at least an interior pellet inwardly to be horn-like in the pellet 12 in the described several piece that surrounds cydariform core 6, so that conveniently during the demoulding take out all interior pellets.

The end face of the end face of described circular cone stage body 10 and cydariform core 6 can have several minor grooves, so that when cast increases the flowability of liquid.

The utility model bronze drum mould structure is simple, adopts the modelled after an antique little bronze drum of materials such as its copper, the aluminium matter that can produce profile fineness, clear patterns, zinc-containing alloy, and production efficiency height, cost are low, can produce in batches, are fit to the modern production requirement.

Description of drawings

Fig. 1 is the structural representation of the utility model bronze drum mould.

Fig. 2 is the schematic top plan view after Fig. 1 takes off cover plate 1 and circular retainer 3.

The specific embodiment

As depicted in figs. 1 and 2, pedestal 7 is arranged at the bottom of the utility model bronze drum mould, there is circular cone stage body 10 middle part of pedestal 7, there is cover plate 1 top of circular cone stage body 10, the periphery of circular cone stage body 10 tightly is with the cydariform core 6 that is stuck on the pedestal 7, cydariform core 6 is surrounded by pellet in the several piece 12, wherein there is an interior pellet inwardly to be horn-like, so that when the demoulding, can conveniently take out all interior pellets, the top of cydariform core 6 has circular draw-in groove 14, be equipped with circular retainer 3 in the circular draw-in groove 14, the periphery of cydariform core 6 is with the cydariform exocoel 5 that is complementary with cydariform core 6, cydariform exocoel 5 surrounds by three block external cavity pieces 13 are hinged, and wherein the two side ends of a block external cavity piece is hinged by bearing pin 11 with other the exocoel piece of two band handles 8 respectively, connected by movable pin 9 between the two block external cavity pieces of band handle 8; Between cydariform core 6 and the cydariform exocoel 5, all leave the gap between cydariform core 6 and circular cone stage body 10 and the cover plate 1, circular draw-in groove 15 is arranged at the top of cydariform exocoel 5, and cover plate 1 has the bulge loop 4 that can snap in circular draw-in groove 15 and has plug hole 2; The bottom surface of the end face of the end face of circular cone stage body 10 and cydariform core 6 and circular draw-in groove 15 maintains an equal level, and the end face of the end face of circular cone stage body 10 and cydariform core 6 has several minor grooves, so that increase the flowability of liquid during cast.

In order to make the bronze drum outer surface of making that pattern be arranged, can be carved with pattern at the inwall of cydariform exocoel and the bottom surface of cover plate.

When making bronze drum, earlier movable pin 9 is taken off, promoting two handles 8 opens the exocoel piece, pellet 12 snaps in the draw-in groove of pedestal in several of cydariform core 6 constituting then, and be stuck in by circular retainer 3 in the circular draw-in groove 14 at cydariform core top the cydariform core is locked, the exocoel piece that closes then connects and locking with movable pin 9 again, again cover plate 1 is covered, and its bulge loop 4 is stuck in the circular draw-in groove 15 of exocoel piece.

During cast, earlier suitable temperature is arrived in Metal Melting, mould and die preheating adopts the centrifugal casting mode to pour into a mould behind suitable temperature, cast liquid enters from the plug hole 2 on the cover plate 1, because the end face of circular cone stage body 10 end faces and cydariform core 6 has several minor grooves, can make in the gap between cast liquid easier inflow cydariform core and the cydariform exocoel, after liquid to be cast is filled all gaps, can stop cast, can carry out die sinking behind the metal cooling shaping has operated, promptly take off cover plate 1 and movable pin 9 earlier, turning handle 8 is opened the exocoel piece then, take out the bronze drum product of pedestal 7 and tape drum core 6 respectively, just take out cydariform core 6 after waiting the bronze drum product to cool off fully, extract out at first inwardly when getting the cydariform core inwardly be trumpet-shaped in pellet, and then take out pellet and circular retainer 3 in remaining, can obtain the bronze drum finished product.
