Abstract
The utility model discloses a kind of forming bench panel and mould sealing mechanism, comprise table board and mould.Mould is surrounding and top seal, and the casing of bottom opening, tips upside down on table board.The edge that the bottom opening of mould contacts with table board is provided with seal groove.In seal groove, be provided with air bag.Air bag is provided with air valve.Air valve is through inside and outside mould tank wall communicated air bags.The utility model has adopted bellows seal, compares traditional sealing means such as seal ring, sealing joint strip.Bellows seal is more convenient in the time of die sinking, only needs to discharge or extract the air in air bag, loses sealing effect between mould and table board, and the inside and outside air pressure of mould can reach balance, is more prone to die sinking.
Description
Technical field
The utility model relates to die molding machine.
Background technique
In a lot of die molding machines, a lot of moulds need to be realized mould-forming under airtight certain high temperature.Between mould and forming bench panel, conventionally adopt seal ring to realize sealing.Owing to producing air negative pressure after High-temperature cooling in Die Box in casing.Negative pressure in casing makes the sealing between table board and mould be difficult to open, die sinking difficulty.
Summary of the invention
Problem to be solved in the utility model: under traditional sealing means, module, after die forming machine moulding is cooling, produces air negative pressure in Die Box, makes die sinking difficulty.
For addressing the above problem, the scheme that the utility model adopts is as follows:
A kind of forming bench panel and mould sealing mechanism, comprise table board and mould; Described mould is surrounding and top seal, and the casing of bottom opening is buckled on described table board; The edge that the bottom opening of described mould contacts with table board is provided with seal groove; In described seal groove, be provided with air bag; Described air bag is provided with air valve; Described air valve is through inside and outside mould tank wall communicated air bags.
Technique effect of the present utility model is as follows: the utility model adopts bellows seal to replace traditional seal ring sealing.Under the sealing means of this air sac type, can realize sealing and Kaifeng by controlling air bag inner air pressure.In the time that mould need to seal, in air bag, fill air; In the time that mould need to break a seal, only need discharge or extract the air in air bag, between mould and table board, lose sealing effect, the inside and outside air pressure of mould can reach balance, is more prone to die sinking.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As shown in Figure 1, a kind of forming bench panel and mould sealing mechanism, comprise mould 1 and table board 2.Mould 1 is surrounding and top seal, the casing of bottom opening.Mould 1 is buckled on table board 2.Table board 2 seals mould 1 bottom opening by bolt 21, thus the molding cavity sealing in the interior formation of table board 2 and mould 1.On the edge contacting with table board 2 at the bottom opening of mould 1, be provided with seal groove 11.Seal groove 11, around the bottom opening of mould 1, is arranged lopping along the bottom margin of mould 1.In seal groove 11, be provided with air bag 3.Air bag 3 is for being surrounded the structure of cavity, the bottom opening lopping along seal groove 11 around mould 1, and integrated arrangement by elastic material.Air bag 3 is provided with air valve 31.Air valve 31 is through inside and outside the tank wall communicated air bags of mould 1.The degree of depth and the width of the size of air bag 3 and seal groove 11 match.
Working principle of the present utility model is as follows: in the time of matched moulds or patrix; mould 1 is bolted on table board 2, then opens air valve 31 rear toward the interior perfusion high-pressure air of air bag 3, and air bag 3 is expanded; then close gas check valve 31, thereby make sealing between mould 1 and table board 2.As form removal or Xie Moshi; first open air valve 31; air in release or extraction air bag 3; between mould 1 and table board 2 owing to having lacked the sealing of air bag 3; make cannot seal in the mold cavity between mould 1 and table board 2; ambient air flows in mold cavity naturally, makes the inside and outside air pressure of mould can reach balance, is more prone to die sinking.
Claims (1)
