The specific embodiment
See also shown in each figure, in the utility model one preferred embodiment the mould vacuum (-tight) housing spare that provides and the combined structure 10 that squeezes the tube discharge end, it squeezes barrier part 40 by a connecting piece 20, a vacuum (-tight) housing spare 30 and and is formed.
This connecting piece 20 has a microscler hollow body 21, one first connects hole 22 and one second connects hole 23 and provides respectively on this body 21 major axis two ends, also coaxial each other major axis corresponding to this body 21, and make this first aperture that connects hole 22 greater than this second aperture that connects hole 23.
This vacuum (-tight) housing spare 30 has the through hole 32 of hollow cover body 31, one appropriate sizes of the saturating sky of the opposing end in ends two, top to be located on these cover body 31 1 lateral body walls, in order to the inner space and the external world that is communicated with this cover body 31.
Should squeeze barrier part 40 and squeeze tube for the ejaculation of commonly using, have one in order to the raw material heating is melt into the crowded tube 41 of column of molten, and one be located at this and squeeze the column discharge end 42 of tube 41 axiss of a cylinder one end in order to fused raw material is penetrated, and make that this discharge end 42 is coaxial to be slidably connected to this and second to connect in the hole 23, this connecting piece 20 is slidably connected on this crowded barrier part 40 by location suitably.
Composition by above-mentioned member, when this mould vacuum (-tight) housing spare is applied on the industry with the combined structure 10 that squeezes the tube discharge end, wherein, the technology contents of mould vacuum environment is provided and should squeezes barrier part 40 is injected raw material mould inside mould chamber via the mould material hole technology contents about this vacuum (-tight) housing spare 30, the category that belongs to known techniques, promptly old for holding no longer in addition in this.
And need be illustrated be: when this vacuum (-tight) housing spare 30 cover caps in mould week rear flank, can move start by the seat that advances of this crowded barrier part 40, use the locus that changes this connecting piece 20, so that the body 21 major axis one end end end of this connecting piece 20 is connected on cover body 31 body walls of these through hole 32 all sides airtightly, this first connect hole 22 and with these through hole 32 coaxial communicating, make that this body 21 is inner to be connect hole 22 with these cover body 31 inside via this through hole 32 and first respectively and communicate with each other, and state by this body 21 major axis one end butt, so that the locus of this connecting piece 20 obtains to fix, and do not change the position with the into start that continues of this crowded barrier part 40, hereat, 42 of this discharge ends move along self axis of a cylinder axle that continues, and second connect hole 23 slippages and pass this body 21 inner spaces by this that slips, via respectively this first connects hole 22 and through hole 32 stretches in these cover body 31 inner spaces, and the discharging port is connected on the sprue of mould, in the material injecting mould that will squeeze in the tube 41.
According to above-mentioned, when this body 21 is connected to this cover body 31 airtightly with an end when, with this vacuum (-tight) housing spare 30 cover caps in existing because of this through hole 32 during side in mould week but not the state that is sealing acquire change, and the inner space that makes this vacuum (-tight) housing spare 30 reaches the state of space sealing via this connecting piece 20, negative pressure device by the outside is detached the gas of this cover body 31 with body 21 inner spaces, thereby provide institute's cover cap mould suitable vacuum environment, and under these environment, allow to squeeze barrier part 40 with in the material injecting mould, to adapt to the demand of creating conditions.
Except that on take off the disclosed concrete technology contents of embodiment, can guarantee further that the state that this body combines with this cover body butt is maintained at a suitable following time of airtight conditions, then can on this body, apply with suitable external force, make being connected between this body and cover body be subjected to keeping under suitable the applying of external force suitable bonding state, particularly, these external force provide can such as in second preferred embodiment of Fig. 4 announcement, be set on this discharge end 42 ' with a spring 50 ', and two ends are connected between crowded tube 41 ' and body 21 ' respectively, in order to elastic force to be provided, flexibly this body 21 ' is positioned the state with this cover body 31 ' butt; Or also can disclose as the 3rd preferred embodiment of Fig. 5, squeeze tube 41 in this " hold last appropriate location axle to establish a fluid pressure cylinder 50 ", and with this fluid pressure cylinder body 50 " exert oneself axle head and this body 21 " join, with by this fluid pressure cylinder body 50 " footpath is self-driven and locate this body 21 " the position.
