Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments of the invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the accompanying drawing provided.
The schematic diagram of a kind of die mould method that Fig. 1 provides for the embodiment of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiments provide a kind of die mould method, as shown in Figure 1, the schematic diagram of a kind of die mould method that Fig. 1 provides for the embodiment of the present invention.This die mould method comprises the steps:
S1: installation mold;
Wherein, the cavity portion of described mould is roughly the same with the shape of the glasswork that will make, and described mould is divided into upper die and lower die two portions, wherein patrix is arranged on fluid pressure drive device, counterdie is arranged on operator's console, and ensures that installing the latter two aligns pressure center in vertical direction, and patrix is under the driving of fluid pressure drive device, can move back and forth in vertical direction, and can accomplish when moving to least significant end to fit completely with counterdie.
S2: thermoplastic glass;
Wherein, by glass heats to softening temperature more than+50 DEG C, its appropriateness can be made softening, is convenient to compression moulding.
S3: the glass after softening is put into described mould, glasswork redundance is extruded, clear portions in the middle of only retaining, obtains work in-process;
Wherein, under the effect of drive unit, patrix moves down, the glass after compression is softening, and after final compression, patrix arrives desired location, and the glass after softening is pressed into an organic whole, and its shape is identical with the cavity portion of mould.Glasswork redundance can be extruded in pressing process, clear portions in the middle of only retaining, obtains work in-process.By this step, the smooth and glasswork of light of surrounded surface can be obtained, and overflow more than part, also need to carry out following process process.In addition, the glass of extrusion can also recycling, and therefore, this method not only reduces the process of weighing to frit, saves cost of labor, also a saving raw material.
S4: following process is carried out to the upper surface of finished product or lower surface.
Wherein, it should be noted that, select land to be upper surface or lower surface according to the shape of product.Utilize the glasswork that method provided by the invention is suppressed, upper surface or lower surface is only had to need to carry out following process process, make its smooth surface, and all the other each faces are exactly smooth after pressing, redundance no longer needs to carry out subsequent disposal, thus decrease the workload of following process, improve working efficiency, reduce production cost.
In the above-mentioned methods, described mould can preferably past the later mould of fire polishing.Before glass is suppressed, first utilize fire polishing machine to carry out polishing to the internal surface of mould, make mould inner surface more smooth, thus the surface of the glasswork suppressed can be made more smooth, reach optical grade requirement.
In the above-mentioned methods, described glass can preferably utilize levigation method to carry out to corner later glass of polishing.Utilize levigation method to polish off the acute angle of glass, make glass more mellow and full, thus make the surface of the glasswork suppressing out more mellow and full and smooth, avoid fold, thus improve the quality of product.
In the above-mentioned methods, split type dustless softening furnace can be preferably utilized to carry out thermoplastic to described glass.The split type design of this dustless softening furnace has takes up an area the advantages such as space is little, disassembly and assembly are convenient, and the flow process of thermoplastic glass can be made more clear smooth and easy.
In the above-mentioned methods, the cumulative volume putting into the glass of described mould is preferably greater than the volume of described mould.Due in die mould process, need glasswork redundance to extrude, only retain middle clear portions, therefore will ensure the integrity of glasswork, just need to fill in a mold the glass that cumulative volume is greater than mold volumes.And the glass of filling is more, the smooth surface of glasswork and the stability of size and dimension of compacting more can be ensured.
In the above-mentioned methods, hydropress is preferably utilized to carry out die mould.Hydropress can provide enough powerful power for die mould, and cost is lower, therefore preferably utilizes hydropress as the drive unit of die mould.
In the above-mentioned methods, before following process is carried out to the upper surface of finished product or lower surface, preferably comprise: remove the edge section of overflowing.Due under powerful pressure, the edge section of glass is extruded out, therefore preferably first removes these edge sections of spilling, then just can better carry out deepfreeze operation.
In the above-mentioned methods, preferably lancinate with glass and draw and knock out the edge section of spilling.Utilize glass cutter first to cut the edge section of overflowing to draw, the connection between edge section and the body of glasswork just can be made to be in metastable condition, knock, be just easy to remove edge section, this is a kind of method of efficient removal edge section as seen again.
In the above-mentioned methods, the following process of carrying out described work in-process upper surface or lower surface preferably comprises grinding, polishing and cleans.The upper surface or lower surface of removing the later glasswork in edge section are first ground, remove residual less projection, the mode that recycling comprises fire polishing carries out polishing to upper surface or lower surface, the two is made to become the surface of light, last effects on surface does further clean, thus completes the making processes of glasswork.
Known by foregoing description, die mould method provided by the present invention can suppress each smooth glasswork around, thus only need to carry out subsequent machining operations to upper surface or lower surface, effectively reduce the workload of pressed glass goods, improve production efficiency.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
