Description
Technical field
The present invention relates to medical injection mold technical field, a kind of specially novel environment friendly plastic cement product injection mould goes out
Die device.
Background technology
For the reeded medical-grade plastics product of inside shaping (for example：Medical-grade plastics bedpan；Medical-grade plastics pallet；It is medical
Plastic cement measuring cup etc.) for, during being molded by injection molding manner, for convenience of the shaping matter for being stripped and ensureing plasthetics
Amount, is stripped often through pitched roof mechanism to above-mentioned groove structure.Such as Patent No. 201210350569.1, patent name
For a kind of patent of the pitched roof mechanism applied to injection mold, its angle ejector rod, sliding shoe and fixed block are respectively adopted movable
Flexible way connection, it is good with using effect, be not in the stuck advantage of angle ejector rod.But the characteristics of due to structure itself,
In the presence of following deficiency：(1) space used in this structure is larger, through being commonly encountered the problem of interfering with other ejector members；(2) by
Angular movement state is constantly in oblique top, stuck or fracture phenomenon is also easy to produce；(3) due to angular compliance, in practical set
When the factor that influences it is relatively more, assembly process process is poor；(4) parts are more, and expense is naturally of a relatively high.
The content of the invention
The present invention can effectively solve the problem that above-mentioned not enough medical injection according to above-mentioned deficiency of the prior art there is provided a kind of
The demoulding device of mould.
In order to achieve the above object, the present invention takes the technical scheme to be：
A kind of demoulding device of novel environment friendly plastic cement product injection mould, including base, lower ejector retainner plate, upper ejector retainner plate, lead
To bar and support bar, described base is provided with fixed block and two support bars, and post upper is provided with injection mold, fixed block
On be fixed with guide rod；Upper ejector retainner plate and lower ejector retainner plate, support bar and upper ejector retainner plate, lower thimble are provided between two support bar
Plate junction is provided with sliding guide groove, and the upper ejector retainner plate and lower ejector retainner plate are screwed connection；The upper ejector retainner plate is with
It is provided with ejector retainner plate in chute, chute and angle ejector rod is slidably fixed with by pin.
Preferably, described upper ejector retainner plate or lower ejector retainner plate are provided with clip.
Preferably, described fixed block is demountable structure or pre-buried structure with base.
Preferably, two described support bars are symmetricly set on base.
Preferably, the longitudinal cross-section of described sliding guide groove is T-shaped, the longitudinal direction of upper ejector retainner plate and lower ejector retainner plate is cut
Face is in " T " font being engaged with sliding guide groove.
The beneficial effects of the invention are as follows：The mould unloading structure that the present invention is designed is compared with conventional ramp-roof structure, with as follows
Advantage：(1) spatial volume that the present apparatus is used is small, it is to avoid interfere with other ejecting mechanisms；(2) cunning that this structure is produced with core rod
It is dynamic short apart from the small, time, stuck or fracture is not likely to produce, subsequent maintenance cost is low；(3) assembly technology is with ordinary straight top mechanism class
Seemingly, accurate size is easily calculated, assembly technology is optimized；(4) part is few, and expense saves expense 30% than conventional pitched roof mechanism
More than.
