Abstract
The utility model discloses a kind of external shutter, be applied in point pattern, described point of pattern comprises the first liftout plate, the second liftout plate and the 3rd liftout plate that superpose successively, described shutter comprises one end and is fixed on latch on the first liftout plate, be fixed on the locking seat on the second liftout plate, be fixed on the latch hook holder on the 3rd liftout plate, described locking seat and latch hook holder are provided with the through hole passed for latch; Described locking seat and latch hook holder are also provided with the lockable mechanism pinning latch.The utility model solves conventional rubber shutter and magnetic on/off device poor stability, the problem easily got loose, and this external shutter structure is simple, convenient for installation and maintenance, can be widely used in Mould Machining field.
Description
Technical field
The utility model relates to Mould Machining field, especially relates to a kind of external shutter.
Background technology
Injection mould, when carrying out repeatedly somatotype, needs between liftout plate to control its sequencing by shutter, has reached the object of step-by-step parting.Usually the shutter selected is built-in, probably can be divided into beam China, one is resin shutter, is that the frictional force of the resin barrel relying on two ends to be separately positioned on adjacent two liftout plates is fixed two liftout plates, Long-Time Service resin is easy to wear, thus affects the stability of die sinking order.Another kind is magnetic on/off device, is to rely on the magnet be arranged on two liftout plates to be mutually fixed, and this structure also exists magnetic force and weakens, the problem of poor stability.
Utility model content
The purpose of this utility model is to provide a kind of external shutter, solves the problem of existing mold shutter poor reliability.
The utility model solves the technical scheme that its technical problem adopts: a kind of external shutter, be applied in point pattern, described point of pattern comprises the first liftout plate, the second liftout plate and the 3rd liftout plate that superpose successively, described shutter comprises one end and is fixed on latch on the first liftout plate, be fixed on the locking seat on the second liftout plate, be fixed on the latch hook holder on the 3rd liftout plate, described locking seat and latch hook holder are provided with the through hole passed for latch; Described locking seat and latch hook holder are also provided with the lockable mechanism pinning latch.
Further, described lockable mechanism comprises one end to be fixed and the latch hook linked up with holder pin and be connected, and latch hook is placed in through hole; Be arranged on the latch segment in locking seat, described latch hook be provided with the barb coordinated with latch segment; The ejector spring for making latch hook rotate around pin is also provided with in described latch hook holder.
For preventing latch segment from departing from barb, the below of described latch segment is also provided with holddown spring.
For convenience of the insertion of latch, the end of described latch is provided with spigot surface, and the movable end of described latch segment is provided with the inclined-plane suitable with spigot surface.
The beneficial effects of the utility model: by arranging latch and lockable mechanism between three pieces of liftout plates, first carry out locked to wherein two pieces of liftout plates, wherein one piece of liftout plate are first departed from, and structure is reliable, and coupling mechanism force is strong, and mistake in passing can not occur.Described locking mechanism mechanism is simple, and coupling mechanism force is large, operates steadily, and not fragile, substantially increases the reliability of mould somatotype.
Below with reference to drawings and Examples, the utility model is described in detail.

Detailed description of the invention
Embodiment, as shown in Figures 1 to 3, a kind of external shutter, be applied in point pattern, described point of pattern comprises the first liftout plate 1, second liftout plate 2 and the 3rd liftout plate 3 that superpose successively, and described shutter comprises one end and is fixed on latch 4 on the first liftout plate 1, is fixed on the locking seat 7 on the second liftout plate 2, be fixed on the latch hook holder 5 on the 3rd liftout plate 3, described locking seat 7 and latch hook holder 5 are provided with the through hole 10 passed for latch 4; Described locking seat 7 and latch hook holder 5 are also provided with the lockable mechanism pinning latch 4.Described locking seat 7 comprises and being superimposed and the cushion block 71 be bolted and cover plate 72, and Split type structure is convenient to be safeguarded being arranged on inner latch hook and adjusting, and also facilitates the assembling of latch hook and latch segment simultaneously.
Described lockable mechanism comprises one end to be fixed and the latch hook 6 linked up with holder 5 and be connected by pin 15, and latch hook 6 is placed in through hole 10; Be arranged on the latch segment 8 in locking seat 7, described latch hook 6 be provided with the barb 9 coordinated with latch segment 8; The ejector spring 11 for making latch hook 6 rotate around pin 15 is also provided with in described latch hook holder 5.The below of described latch segment 8 is also provided with holddown spring 12.By the pressure of ejector spring 11 and holddown spring 12, latch segment 8 and latch 4 are pressed in through hole 10.The spring force of described ejector spring 11 is greater than holddown spring 12.
The end of described latch 4 is provided with spigot surface 13, and the movable end of described latch segment 8 is provided with the inclined-plane 14 suitable with spigot surface 13.Latch 4 is facilitated to insert.
When the mold is closed, latch is coordinated by spigot surface and inclined-plane, the downforce of latch passes to latch hook, latch hook first overcomes the spring force of holddown spring, make the rotation of latch hook abdicate space to insert for latch, latch continues motion, compresses ejector spring and holddown spring, until the first liftout plate, the second liftout plate and the 3rd liftout plate overlap under the pressure of latch simultaneously.
When the mold is open, due to the second liftout plate and the 3rd liftout plate fixing by latch hook together with, therefore, latch moves together with the first liftout plate, and the first liftout plate is first separated with the second liftout plate.Latch continues motion, when latch is separated with latch hook, latch hook rotates around pin under the acting in conjunction of ejector spring and holddown spring, simultaneously, because the spring force of ejector spring is greater than holddown spring, after holddown spring moves to the limit, ejector spring continues to apply spring force to latch hook, barb on latch hook is separated with latch segment, thus the second liftout plate is separated with the 3rd liftout plate.
