Abstract
The utility model provides a kind of high technology ceramics hot compression moulding die air discharge duct, comprise the mould be combined into by feedboard, die cavity, mating die plate, feedboard is provided with charging aperture, it is characterized in that: offer several shallow air drain coordinating the lower surface of template upper surface or die cavity, shallow air drain is communicated with die cavity inside and mold exterior, the shallow air drain degree of depth is 0.15mm-0.25mm, and all shallow air drains connect the 50%-80% of the girth of the die cavity inner wall section of summation corresponding to it of the width of one end of die cavity inside.The utility model is owing to being provided with some shallow air drains, thus more existing dark narrow air drain, and bubble discharge path is wider, bubble discharge faster evenly, air discharge duct is leakiness material not, solves the problem that bubble is wrapped up in porcelain piece inside.
Description
Technical field
The utility model belongs to a kind of ceramic production device, particularly relates to a kind of structure of high technology ceramics mould.
Background technology
The discharge of tradition high technology ceramics hot compression moulding die type chamber air utilizes the fit clearance of mould itself often, or deeply narrow air drain (being the way following plastic injection mould substantially) is opened at gas shutoff position, consequently the bubble on surface is the reduction of, but air entrapment is still much rolled in the inside.This can cause the product scrapped because of bubble in a large number for surface needs the porcelain piece of grinding.
Utility model content
The utility model provides a kind of high technology ceramics hot compression moulding die air discharge duct, its objective is the shortcoming solving prior art and exist, the air in die cavity can be discharged rapidly, and avoid inside to wrap up in the problem of bubble.
The utility model solves the technical scheme that its technical problem adopts:
The hot compression moulding die air discharge duct of a kind of high technology ceramics, comprise the mould be combined into by feedboard, die cavity, mating die plate, feedboard is provided with charging aperture, it is characterized in that: offer several shallow air drain coordinating the lower surface of template upper surface or die cavity, shallow air drain is communicated with die cavity inside and mold exterior, the shallow air drain degree of depth is 0.15mm-0.25mm, and all shallow air drains connect the 50%-80% of the girth of the die cavity inner wall section of summation corresponding to it of the width of one end of die cavity inside.
Usefulness of the present utility model is:
The utility model is owing to being provided with some shallow air drains, thus more existing dark narrow air drain, and bubble discharge path is wider, bubble discharge faster evenly, air discharge duct is leakiness material not, solves the problem that bubble is wrapped up in porcelain piece inside.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model sectional structure chart;
Fig. 2 is the A-A profile of Fig. 1.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the utility model is the hot compression moulding die of a kind of high technology ceramics, the mould that this mould is combined into by feedboard 1 from top to bottom, die cavity 2, cooperation template 3, feedboard 1 is provided with charging aperture 11, from charging aperture 11, raw material hot pressing note is entered die cavity 2 during use inner, after shaping, obtain porcelain piece 4.
Four shallow air drains 21 are offered at the lower surface of die cavity 2, shallow air drain 21 is communicated with die cavity 2 inside and mold exterior, shallow air drain 21 degree of depth is 0.15mm-0.25mm, such as 0.2mm can be got, all shallow air drains 21 connect the 50%-80% of the girth of the inner wall section 22 of the die cavity 2 of summation corresponding to it of the width of one end 210 of die cavity 2 inside, such as optional 50%, wider exhaust is faster.Because the girth of the inwall of die cavity 2 is identical with the girth of the porcelain piece 4 of its corresponding part, therefore can think that all shallow air drains 21 connect the 50%-80% of the girth of the machined surface part of the porcelain piece 4 of summation corresponding to it of the width of one end of the inside of die cavity 2.
In other embodiments, also can offer shallow air drain at cooperation template 3 upper surface, shallow air drain is communicated with the inner and mold exterior of die cavity 2 and can be vented, identical with the effect of above-described embodiment.
Large-area so shallow air drain not only makes the air in die cavity be discharged rapidly, also can not cause the precision affecting product because air discharge duct leaks material, thoroughly solves the difficult problem wrapping up in bubble at one stroke.
