Description

Flute and mould thereof

Technical Field

The utility model relates to a musical instrument technical field, specifically say, in particular to flute and mould thereof.

Background

The flute is an ancient Chinese musical instrument and is one of the most representative and ethnic wind instruments in the Chinese musical instrument. The flute is the tubulose, is equipped with the flute stopper near flute head one end, and it has ten flute holes to open on the pipe shaft of flute stopper to flute tail, and ten flute holes are one from flute stopper to flute tail and blow hole, a diaphragm orifice, play sound hole after two, six sound holes and two play sound holes before. Traditional bamboo flute is made by bamboo, and through strict material selection and refining, the bamboo flute can have good intonation and tone quality. However, bamboo materials are easily deformed under the influence of temperature, and the timbre and the tone accuracy can be changed under different temperature environments; along with the lengthening of playing time, the tone and the intonation also change, which causes the poor playing effect. Moreover, bamboo flutes can be made manually, and because the shape of each bamboo is different, the position and the shape of each flute hole also need to be modulated manually, the high-end bamboo flute is high in labor cost and high in price, and cannot be produced in batch and can be met but cannot be obtained. Some plastic flutes produced in batches are available in the market and have price advantage, but the tone of the existing plastic flutes can not be comparable with that of bamboo flutes all the time.

SUMMERY OF THE UTILITY MODEL

To the defect among the prior art, one of the purposes of the utility model is to provide a flute, make it not only possess good intonation and tone quality, can batch production moreover.

The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides a flute, includes the flute body of plastics material, the body has flute stopper and ten flute holes, body and inner chamber all are the toper to body and inner chamber flute tail one end all are thinner than flute head one end the wall is equipped with the bar line of arranging along its length direction in the body.

The utility model discloses a set up body and inner chamber all and be the toper of imitative bamboo flute to including the cavity wall set up the bar line of imitative bamboo flute, thereby make the flute of plastics material not only have the tone quality and the accuracy that can compare favourably with the bamboo flute, can batch production moreover, make ordinary consumer also can buy the flute with high-end bamboo flute with the quality.

The body is injection molded from epoxy resin. The flute made of the epoxy resin is slightly affected by temperature, and the tone of the flute is stable no matter the flute is used for temperature change or is played for a long time, so that the plastic flute achieves the effect of an iron core flute in the bamboo flute.

The flute holes on the body are in a conical shape with a small outside and a large inside. Is favorable for ensuring that the flute has good timbre.

The flute holes are oval, and the long axes of the oval flute holes are arranged along the length direction of the body. Further being beneficial to ensuring that the flute has good timbre.

The outer wall of the body is provided with a plurality of convex rings, and the outer wall of each convex ring is provided with annular grains. The convex ring plays a decorative role on one hand and can prevent slipping on the other hand.

Another object of the present invention is to provide a flute mold for facilitating mass production of flutes.

The above technical purpose of the present invention can be achieved by the following technical solutions: a mould for preparing the flute comprises a lower mould, a core mould positioned in the lower mould and an upper mould buckled on the lower mould, wherein groove-shaped body cavities matched with the body appearance are formed in the lower mould and the upper mould, both ends of the body cavities of the lower mould and the upper mould are connected with pouring cavities thicker than the body cavities, and both ends of the top of the upper mould are provided with pouring ports communicated with the two pouring cavities; the outer ends of the pouring cavities of the lower die and the upper die are both connected with core die supporting grooves which are thinner than the body cavity; the mandrel includes the dabber of stereoplasm and the silica gel core of cover outside the dabber, the silica gel core coincide with body inner chamber, the both ends of silica gel core coincide with the lower mould and the mandrel support groove on the mould, the outer wall arch of silica gel core forms and the flute hole one-to-one and the identical boss of molding, at each the top of boss all inlays and is equipped with first magnet go up mould and lower mould in all inlaying and be equipped with the second magnet with first magnet one-to-one.

The flute is injection molded by the mold, so that the flute is easy to produce and stable and reliable in quality. The core mold comprises a hard core shaft and a silica gel core body, after forming is completed, the upper mold and the lower mold are removed firstly, then the core shaft is pulled out, and the core body is soft, so that a boss of the core body extending into the flute hole can be pushed into the flute inner cavity by hands, and demolding of the silica gel core body is facilitated. The arrangement of the boss on the silica gel core body, the first magnet and the second magnet on the upper die and the lower die facilitates accurate positioning and forming of flute hole parts.

The core mold is divided into two sections which are detachably connected from the flute plug to any position between flute heads. The core mould is divided into two sections, so that the core mould of the flute is convenient to refine, and the precision of the flute from the flute plug to the flute tail section is particularly favorable to be ensured.

The core shafts of the two sections of core molds are connected through a third magnet, so that the two sections of core molds are detachably connected. The detachable connection structure of the core moulds at the two ends is simple and convenient to use.

And a through hole along the axial direction of the mandrel is arranged in the mandrel. The through hole is arranged, so that the mandrel can be more easily drawn out during demolding.

And a rubber tube is padded between the mandrel and the silica gel core body. The assembly of the core mold is made easier.

Has the advantages that: the utility model discloses a set up the toper that is imitative bamboo flute with body and inner chamber all to the cavity wall sets up the bar line of imitative bamboo flute, thereby provides a tone quality and sound accuracy can be with the plastics flute that the bamboo flute compares favourably, and provides a mould that is used for this plastics flute of batch production.
