Description

A kind of mould ejection takes off back-off mechanism
Technical field
It the utility model is related to technical field of mold, and in particular to a kind of mould ejection takes off back-off mechanism.
Background technology
After injection molding is carried out to plate product using mould, since the surface of plate product has cavernous structure, hole Shape structure has the small back-off structure interferenceed with mold cores, such as 0.5-1mm thickness, when mold releasability separates, is pacifying Under under the movement of thimble and the movement of Ejector Retainer Plate on thimble panel during outside ejecting product, which falls Button can be interfered with mold insert, can not realize the smooth demoulding, can be to the inside back-off structure of cavernous structure if forced stripper mechanism Cause to damage.
Utility model content
The purpose of this utility model is to be directed to technological deficiency existing in the prior art, and provides a kind of mould ejection and take off down Buckle mechanism.
Technical solution is used by realize the purpose of this utility model:
A kind of mould ejection takes off back-off mechanism, including the thimble on thimble panel, and the thimble panel is installed on On Ejector Retainer Plate, connecting rod is installed on the Ejector Retainer Plate, the threaded upper ends of the connecting rod connect one and are used to limit work The limited block of dynamic mold insert stroke, the lower section installation spring of the limited block, the spring pocket is in the connecting rod and is installed on In the spring mounting hole formed on rear pattern plate, the upper end connection of the limited block can be pushed up upwards by the thimble together with product The movable insert gone out.
The bottom of the movable insert has threaded hole, and the center of the limited block has T-shaped through hole, the movable insert It is placed on the limited block, the threaded hole is mutually threadedly coupled with the bolt being placed in the T-shaped through hole.
The T-shaped head that the bottom of the connecting rod is formed is installed in the mounting hole of the Ejector Retainer Plate, from the thimble face Through hole on plate is stretched out through upward.
The utility model is moved by thimble in mould ejection product and drives movable insert to eject direction to product together Movement, it is to be exercised to product be buckled to position be completely exposed the confined planes of mold cores when, under the action of limited block, movable insert Stop motion, back center continue movement by product eject and separated with movable insert, back center return when, by connecting rod one Play movement and movable insert is retracted into reset.
Brief description of the drawings
Fig. 1 is the schematic diagram that mould ejection takes off back-off mechanism;
Fig. 2 is the connection diagram of movable insert and product.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.It should be appreciated that this place The specific embodiment of description only to explain the utility model, is not used to limit the utility model.
Referring to shown in Fig. 1-2, a kind of mould ejection takes off back-off mechanism, including the thimble 3 on thimble panel 2, institute Thimble panel is stated on Ejector Retainer Plate 1, connecting rod 4, the threaded upper ends of the connecting rod are installed on the Ejector Retainer Plate Connection one is used for the limited block 6 for limiting movable insert stroke, the lower section installation spring 5 of the limited block, and the spring pocket exists In the connecting rod 4, and in the spring mounting hole 71 formed on the rear pattern plate 7, the upper end connection of the limited block can be with The movable insert 8 that product is ejected upwards by the thimble together.
The front end of the movable insert has the mold cores for the cavernous structure for forming product, the mold cores and product 102 shape of back-off structure in 100 cavernous structure 101 is consistent, and after moulding, back-off structure 102 exists with mold cores It can be interfered during the demoulding, cause effectively smoothly to demould, for this reason, the utility model will form the cavernous structure of the product Mold insert is designed to mobilizable mold insert, in die sinking, at first drives the mold insert to be moved together to product ejection direction from thimble one It is dynamic, when the position that movable insert moves to the back-off structure 102 is completely exposed the confined planes formed in rear cavity 9, at this time The bottom confined planes (i.e. the contact surface of rear cavity and rear pattern plate) of limited block and rear cavity are in contact, and continue to move to produce by thimble Product continue to the movement of ejection direction, since movable insert 8 by limited block and rear cavity is limited stop motion, so in thimble Under continuous action, product, which is ejected, to be separated and separates with movable insert, thereby realize product ejection and and movable insert Separation.
It should be noted that in the utility model, the structure of the thimble of the mould, thimble panel and thimble top plate is The structure of the ejector pin mechanism of existing mold, the motion control of thimble panel and Ejector Retainer Plate are the thimble movement in existing mold Control technology, no longer describes the structure of the motion control mechanism of control thimble panel and bottom plate in detail herein.
Wherein, the bottom of the movable insert has threaded hole, and the center of the limited block has T-shaped through hole, the work Dynamic mold insert is placed on the limited block, and the threaded hole is threadedly coupled fixation with 10 phase of bolt being placed in the T-shaped through hole.
Wherein, the T-shaped head that the bottom of the connecting rod is formed is installed in the mounting hole of the Ejector Retainer Plate, from the top Through hole on dial plate through stretching out upwards, so when thimble moves upwards, will not thimble panel and Ejector Retainer Plate will not be right Connecting rod forms driving force directly up, but realizes and moved upwards by product to drive the connecting rod and movable insert To product ejection direction movement, and when in thimble return, the driving connecting rod and movable insert return together can be but realized.
The utility model moved in mould ejection product by thimble, by movement of the product to ejection direction and Movable insert is driven to be moved together to product ejection direction, it is to be exercised to be completely exposed the spacing of mold cores to product back-off position During face, under the action of limited block, movable insert stop motion, back center continue movement by product ejection and and movable insert Separation, back center Ejector Retainer Plate and panel control under return when, moved together by connecting rod and movable insert retracted into reset.
The above is only the preferred embodiment of the utility model, it is noted that for the general of the art For logical technical staff, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these change The scope of protection of the utility model is also should be regarded as into retouching.
