Abstract
The utility model discloses a die for manufacturing a glass square rod and belongs to the field of production tools for glass products. The die for manufacturing the glass square rod comprises a flat annular body, wherein a positioning step is arranged on the side of the body; a through hole is formed in the upper end face of the body and comprises four arc-shaped edges; and the arc-shaped edges are connected through transitional chamfers. During use, the die is arranged and positioned at the outlet position of a glass melting furnace through the positioning step, a discharge valve is opened, and melted glass passes through the through hole to form a basically square bar shape; and if compressed air is introduced into the center of the melted glass, a glass tube can be manufactured, and if compressed air is not introduced, a glass bar can be manufactured. During cooling, the four corners of the glass bar are shrunk greatly and the four edges of the glass bar are shrunk slightly; and according to design of the profile of the die, the protruded part during cooling is rightly shrunk to the extent that the surface is flat without warping. The die has a simple structure, is convenient to use and can be used for manufacturing a square glass bar. The glass bar can be used for manufacturing lamps or serve as other decorative materials.
Description
Technical field
The utility model relates to a kind of means of production of glasswork, particularly a kind of mfg. moulding die of square rod glass.
Background technology
In the prior art, when making hollow glass tube, by a mould, this mold center is provided with circular hole, at center of circular hole ventpipe is set simultaneously, blows to the center of glass of melting through ventpipe, forms cavity in center of glass with the glass of melting.Can produce glass round tube like this.Because glass can shrink in process of cooling, and the round tube surface can evenly be shunk, therefore, make pipe and realize than being easier to, still, when making square rod or square tube, adopt existing technology not accomplish owing to expand with heat and contract with cold, melten glass is passed square hole after, glass can shorten sub-circular into, the reason that square glass pipe or glass stick are difficult to make in the prior art that Here it is by automatic folding.
The utility model content
The purpose of this utility model provides a kind of mfg. moulding die of glass square rod, can make fast the glass square rod.
The purpose of this utility model is achieved in that a kind of mfg. moulding die of glass square rod, comprise flat annular body, the body side is provided with positioning step, and the upper surface of body is provided with through hole, described through hole comprises four arc-shaped sides, links to each other through the transition chamfering between the arc-shaped side.
When this device uses, by positioning step its installation is positioned at the outlet position of glass furnace, opens bleeder valve, the glass of melting passes through hole, forms roughly be square bar-shaped; As the center of glass that is engaged in melting passes into pressurized air, can be made into Glass tubing, as not passing into pressurized air, can be made into glass stick.In when cooling, shrink morely at four jiaos of places of glass stick, and that shrink on four limits is less, by the design of die face, make outstanding part when cooling, just be retracted to surfacing, without warpage.This mould structure is simple, and is easy to use, and can make appearance is square glass stick, and this glass stick can be used for the light fixture manufacturing, or uses as other finishing material.
For guaranteeing that arc-shaped side is shrunk to straight flange when cooling off, the action of described arc-shaped side with the ratio of chord length is: (1:5)～(1:6).In this proportional range, arc-shaped side can substantially cool off and be shrunk to straight flange, has guaranteed the precision of glass square rod.
Description of drawings
Fig. 1 is the utility model perspective view.
Fig. 2 is the utility model front view.
Wherein, 1 through hole, 2 bodies, 3 positioning steps, 4 transition chamferings.
Embodiment
As shown in the figure, be a kind of mfg. moulding die of glass square rod, comprise flat annular body 2, body 2 is made by stupalith, and body 2 sides are provided with positioning step 3, and the upper surface of body 2 is provided with through hole 1, through hole 1 comprises four arc-shaped sides, links to each other through transition chamfering 4 between the arc-shaped side.The action h of arc-shaped side with the ratio of chord length l is: (1:5)～(1:6).
When this device uses, by positioning step 3 its installation is positioned at the outlet position of glass furnace, opens bleeder valve, the glass of melting passes through hole 1, forms roughly be square bar-shaped; As the center of glass that is engaged in melting passes into pressurized air, can be made into Glass tubing, as not passing into pressurized air, can be made into glass stick.When cooling, more in four jiaos of place's contractions of glass stick, and the contraction of four limits is less, by the design of die face, arch section is retracted to when cooling just is the plane.
The utility model is not limited to above-described embodiment; on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in protection domain of the present utility model.
Claims (3)
