Description
Technical field
The utility model relates to stripper apparatus fields more particularly to a kind of mould product groove lever to take off device by force.
Background technique
Currently, having many mould products (such as spectacle-frame) in the market is the spectacle-frame note by injection molding, but traditional
Mould is in the structure that the structure that spectacle-frame demoulds is using oblique top, but such demolding structure is complicated, and such de-
Spectacle-frame poor appearance after mode structure demoulding, often causes to pull around lens frame, seriously affects the quality of product.There are also one
Kind pulling force is generated using product back-off, when die sinking holds product, the structure for separating mode and product, but film Renhe product point
From when, product is easy bullet wound, and piece ditch is not deep, and has thimble print.
Summary of the invention
A kind of the purpose of this utility model is to provide quality of mold release mould product ditch that is stable, not will cause damaged products
Slot takes off by force device with lever.
To achieve the above object, the utility model uses following technical scheme:
A kind of mould product groove lever takes off by force device, has forming tank on mold, has one in forming tank
A above holding tank is respectively received and is connected separately with mode piece in slot, it is characterised in that: the device de- by force includes on each holding tank
Respectively arranged mandril, guide part and locating part, mandril, guide part and locating part center are located in a straight line, and mandril is located at
The centre of mode piece, guide part and locating part are located at mandril two sides, and each mode on piece, which is respectively equipped with, to be set on locating part
First through hole and be arranged the second through-hole over the guide, the locating part extends the free end tool of corresponding first through hole
There is spacing head portion；Second through-hole is greater than the free end of guide part, and when product is demoulded from the groove of mold, locating part is buckled in mould
In the first through hole of benevolence piece, mandril jacks up the centre of mode piece, and the second through-hole side of mode piece is jacked up to be turned over around locating part
Turn.
The locating part is bolt.
The first through hole is greater than the cylindrical portion of locating part, less than the limit head of locating part, allows the of mode piece enough
Two through-hole sides are jacked up dynamic around locating part overturning.
The guide part is tapered pole or ladder column.
The radial width of rectilinear direction of second through-hole along mandril, guide part and locating part center is greater than guide part
Free end allows the second through-hole side of mode piece to be jacked up dynamic around locating part overturning enough.
The bottom end of the mandril is fixedly connected on a sliding seat, which is driven by ejection system and slid.
The utility model uses above technical scheme, and when demoulding, each mandril synchronizes outside ejection, each mode piece respectively around
The limit end rotation of corresponding locating part, is similar to lever motion, and warpage occurs in the course of rotation for mode piece, due to injection molding
Mould product there is elasticity, to make product be automatically popped up and realize forced stripper mechanism, the mold demoulded using the above structure is produced
The phenomenon that product are not in product fracture or pull, greatly ensure that the quality of product.In addition, only using mandril backform in a mold
Benevolence does not have to thimble, and not only piece ditch can be deep, but also product surface will not effectively improve product quality there are thimble trace.
Detailed description of the invention
The utility model is described in further details below in conjunction with the drawings and specific embodiments:
Fig. 1 is the schematic diagram of the utility model；
Schematic diagram when Fig. 2 is mode piece overturning in embodiment one；
Schematic diagram when Fig. 3 is mode piece overturning in embodiment two.
Specific embodiment
As shown in one of Fig. 1-3, a kind of mould product groove of the utility model takes off by force device, mold 1 with lever
It is upper that there is forming tank 2, there is more than one holding tank 3 in forming tank 2, respectively receive and be connected separately with mode piece 4 in slot, it is described strong
De- device includes respectively arranged mandril 7, guide part 5 and locating part 6 on each holding tank 3, mandril 7, guide part 5 and locating part 6
Center is located in a straight line, and mandril 7 is located at the centre of mode piece 4, and guide part 5 and locating part 6 are located at 7 two sides of mandril,
The second through-hole 42 for being respectively equipped with the first through hole 41 being set on locating part 6 on each mode piece 4 and being set on guide part 5,
The free end that the locating part 6 extends corresponding first through hole 41 has limit head；Second through-hole 42 is greater than guiding
The free end of part 5, when product is demoulded from the groove of mold, locating part 6 is buckled in the first through hole 41 of mode piece 4, and mandril 7 jacks up
The centre of mode piece 4,42 side of the second through-hole of mode piece 4 is jacked up to be overturn around locating part 6.
The locating part 6 is bolt.
The first through hole 41 is greater than the cylindrical portion of locating part 6, less than the limit head of locating part 6, allows mode piece 4 enough
42 side of the second through-hole jacked up it is dynamic around the overturning of locating part 6.
As shown in Figure 2 or Figure 3, guide part 5 can be tapered pole or ladder column.
Second through-hole 42 is greater than along the radial width of the rectilinear direction at 6 center of mandril 7, guide part 5 and locating part leads
To the free end of part 5,42 side of the second through-hole of mode piece 4 is allowed to be jacked up enough dynamic around the overturning of locating part 6.
The bottom end of the mandril 7 is fixedly connected on a sliding seat, which is driven by ejection system and slid.Use with
The synchronization action of mandril 7 may be implemented in upper structure.Above-mentioned this driving structure, can using it is in the prior art any one.
Working principle of the utility model is: two mandrils 7 synchronize outside ejection when demoulding, two mode pieces 4 respectively around
The limit head-turnover of corresponding locating part 6 simultaneously reaches the position (principle of similar lever) that limit head is limited, in addition, overturning
In the process, guide part 5 can limit mode piece 4 along the rotation of scheduled direction without generating shaking；Process of the mode piece 4 in rotation
Middle generation warpage, since the mould product (spectacle-frame) of injection molding has elasticity, to make mould product be automatically popped up and realize strong
The phenomenon that system demoulding, the mould product demoulded using the above structure is not in product fracture or pulls, it greatly ensure that product
Quality.
