Description
Technical field
It is especially a kind of with the mold for forcing that thimble is driven to retreat the utility model relates to a kind of mold.
Background technique
Existing injection mold includes the cover half fixed plate being located above and underlying dynamic mould fixing plate, is consolidated in cover half
It is connected to solid plate on fixed board, has fixed die insert on solid plate, is connected to moving template, dynamic model by connecting support on dynamic mould fixing plate
There is moving die insert on plate, shape forming cavity between fixed die insert and moving die insert, has and promotion machine on the inside of connection support when molding
The push plate that structure connects.It can be opened after molding, dynamic mould fixing plate, company by runner to type intracavitary injecting material after being molded when work
Connect support, moving template moves down die sinking, then push plate is moved up in the case where the pushing mechanism of equipment drives, and thimble is ejected, thimble will be at
The product of type ejects.The mold of this structure, next time molding when push plate sometimes could not timely return, cause thimble that could not return
Position, molding can have an impact thimble at this time, i.e., thimble first contacts cover half part, easy to damage.
Summary of the invention
The purpose of the utility model is to provide a kind of structures simply, can force the timely return of push plate in molding and drive top
The timely return of needle guarantees that thimble does not contact with cover half, extends the mould that there is pressure thimble to be driven to retreat of die life first
Tool.
The utility model has the mold for forcing that thimble is driven to retreat, including cover half fixed plate and dynamic mould fixing plate,
It is connected to solid plate in cover half fixed plate, has fixed die insert on solid plate, is connected to dynamic model by connecting support on dynamic mould fixing plate
Plate, there is moving die insert on moving template, shape forming cavity between fixed die insert and moving die insert when molding, have on the inside of connection support with
The push plate that pushing mechanism connects.Mandril, the side of mandril automatic moulding plate are vertically fixed with by bolt on the side of solid plate
Extend downwardly, be fixed with locating piece in the side of push plate, there is interstitial hole on locating piece, on the lower end insertion locating piece of mandril in
Between in hole, rotating plate is connected with by shaft on the side of moving template, rotating plate is placed on locating piece below, and rotating plate is angularly disposed,
Limited block is fixed on the side of moving template.
The utility model has the mold for forcing that thimble is driven to retreat, in die sinking since mandril is opposite with solid plate solid
Fixed, moving template moves down, and extraction in the interstitial hole of self-positioning piece of mandril lower part, locating piece moves up therewith when push plate moves up, with into promotion
Rotating plate rotates in an anti-clockwise direction, and rotating plate covers the interstitial hole of locating piece.When molding again, moving template is moved up, mandril lower part
It is inserted into again to the interstitial hole of locating piece, due to there is rotating plate to cover interstitial hole, mandril first pushes rotating plate, then by under rotating plate
Locating piece is pressed, causes push plate to move down in advance, ensure that the thimble of demoulding moves down in advance, when rotating plate rotates clockwise certain angle,
Interstitial hole exposes, and mandril lower end is that can be inserted into the interstitial hole of locating piece.It is simple with structure, can force in molding push plate and
Shi Huiwei simultaneously drives the timely return of thimble, guarantees that thimble does not first contact with cover half, extends the advantages of die life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of embodiment 1 in specific embodiment of the present invention.
Specific embodiment
The utility model has a mold for forcing that thimble is driven to retreat as shown in Figure 1:, including cover half fixed plate 7 and dynamic
Mould fixed plate 1 is connected to solid plate 6 in cover half fixed plate 7, has fixed die insert on solid plate 6, passes through on dynamic mould fixing plate 1
Connection support 12 is connected to moving template 4, there is moving die insert on moving template 4, formation type between fixed die insert and moving die insert when molding
Chamber has the push plate 2 to connect with pushing mechanism in 12 inside of connection support.It is vertically fixed on the side of solid plate 6 by bolt
There is mandril 8, the side of 8 automatic moulding plate 4 of mandril extends downwardly, in the side of push plate 2 is fixed with locating piece 3, has on locating piece 3
Between hole, in the interstitial hole on the lower end insertion locating piece 3 of mandril 8, rotating plate is connected with by shaft 10 on the side of moving template 4
11, rotating plate 11 is placed in below on locating piece 3, and rotating plate 11 is angularly disposed, and limited block 5 is fixed on the side of moving template 4.
The utility model has the mold for forcing that thimble is driven to retreat, in die sinking since mandril 8 and solid plate 6 are opposite
Fixed, moving template 4 moves down, and extraction in 3 interstitial holes of self-positioning piece of 8 lower part of mandril, locating piece 3 moves up therewith when push plate 2 moves up, together
Into having pushed rotating plate 11 to rotate in an anti-clockwise direction, rotating plate 11 covers the interstitial hole of locating piece 3.When molding again, on moving template 4
Move, 8 lower part of mandril is inserted into the interstitial hole of locating piece 3 again, due to there is rotating plate 11 to cover interstitial hole, mandril 8 first under
Rotating plate 11 is pressed, then locating piece 3 is pushed by rotating plate 11, causes push plate 2 to move down in advance, ensure that the thimble of demoulding moves down in advance, when
Rotating plate 11 rotates clockwise certain angle, and interstitial hole exposes, and 8 lower end of mandril is that can be inserted into the interstitial hole of locating piece 3.With knot
Structure is simple, can force the timely return of push plate in molding and drive the timely return of thimble, guarantees that thimble does not contact first with cover half, prolongs
The advantages of long die life.
