Abstract
The utility model discloses a kind of half slide structure sealing ring spot pouring mouth injection mould, comprise base plate (8), top board (7) and be located at base plate (8) and top board (7) between mold base, mold base comprises stripper plate (1), cope match-plate pattern (2), lower bolster (3) and liftout attachment (6), stripper plate (1) and top board (7) near, what arrange downwards successively is upper masterplate (2), lower bolster (3) and liftout attachment (6); Described cope match-plate pattern (2) is connected by nylon shutter (4) with lower bolster (3), in the tracks of stripper plate (1) and cope match-plate pattern (2), be equipped with spacing lower link bar (5), the utility model is simple to operate, knockout course can not damage product, can mold damage yet, reduced production cost.
Description
Technical field
The utility model relates to a kind of half slide structure sealing ring spot pouring mouth injection mould.
Background technology
In product injection moulding process, need three template dies to process, existing three template dies easily produce pit or salient point at gate location when product stripping, so follow-up processing are affected, and finally cause the conduction of product.
Utility model content
The purpose of this utility model is to provide a kind of half slide structure sealing ring spot pouring mouth injection mould.
The technical solution adopted in the utility model is: a kind of half slide structure sealing ring spot pouring mouth injection mould, comprise base plate, top board and be located at base plate and top board between mold base, mold base comprises stripper plate, cope match-plate pattern, lower bolster and liftout attachment, stripper plate and top board near, what arrange downwards successively is upper masterplate, lower bolster and liftout attachment; Described cope match-plate pattern is connected by nylon shutter with lower bolster, is equipped with spacing lower link bar in the tracks of stripper plate and cope match-plate pattern.
As further improvement of the utility model, described spacing lower link bar is provided with damping spring.
As further improvement of the utility model, described liftout attachment comprises the ejector sleeve pressing plate that is connected with base plate and the ejector pin on ejector sleeve pressing plate, and ejector pin is socketed in ejector sleeve cover.
The beneficial effects of the utility model are: the utility model is simple to operate, and knockout course can not damage product, can mold damage yet, reduced production cost.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Fig. 2 is the side view of Fig. 1.
Shown in figure: 1 stripper plate, 2 cope match-plate patterns, 3 lower bolsters, 4 nylon shutters, 5 spacing lower link bars, 6 liftout attachments, 7 top boards, 8 base plates.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model specific embodiment is elaborated.
As depicted in figs. 1 and 2, the present embodiment comprise base plate 8, top board 7 and be located at base plate 8 and top board (7) between mold base, mold base comprises stripper plate 1, cope match-plate pattern 2, lower bolster 3 and liftout attachment 6, stripper plate 1 and top board 7 near, what arrange downwards successively is upper masterplate 2, lower bolster 3 and liftout attachment 6; Cope match-plate pattern (2) is connected by nylon shutter 4 with lower bolster 3, in the tracks of stripper plate 1 and cope match-plate pattern 2, is equipped with spacing lower link bar 5; Spacing lower link bar 5 is provided with damping spring, has reduced 5 collisions of template and spacing lower link bar, and liftout attachment 6 comprises the ejector sleeve pressing plate that is connected with base plate 8 and the ejector pin on ejector sleeve pressing plate, and ejector pin is socketed in ejector sleeve cover.
Operation principle of the present utility model:
Three template die die sinking processes divide secondary to complete, and are between stripper plate and cope match-plate pattern for the first time, are between cope match-plate pattern and lower bolster for the second time:
Die sinking after injection moulding completes, when part of the lower die is subject to injection machine and obtains pulling force, between bolster due to nylon shutter being housed, and between stripper plate and cope match-plate pattern without any obstruction, first (spring is also housed on most cases lower limit lower link bar between stripper plate and cope match-plate pattern) at this moment separate with cope match-plate pattern at pulling force effect lower stripper, cope match-plate pattern is along with lower bolster together motion backward, while moving to setpoint distance, blocked by lower link bar is spacing, because cope match-plate pattern continues motion backward with injection machine, lower link bar is also driven like this, drive again stripper plate to move to setpoint distance, stripper plate and top board are opened, so that stub bar falls, after setpoint distance has moved, lower link bar and part of the upper die stop motion,
Injection machine continues motion backward, and pulling force constantly increases, and while surpassing nylon shutter coupling mechanism force, cope match-plate pattern and lower bolster are opened;
At this moment ejector sleeve sleeve starts to eject motion, and shaped article is ejected.
Below by reference to the accompanying drawings embodiment of the present utility model is described, but the utility model is not limited to above-mentioned embodiment, in the ken possessing at affiliated technical field those of ordinary skill, can also under the prerequisite that does not depart from the utility model aim, make a variety of changes.
