Abstract
The invention discloses a novel keycap in-mould ejector cut-off mechanism. The novel keycap in-mould ejector cut-off mechanism is characterized in comprising a first segment plate ejector mechanism main body, a second segment plate ejector mechanism main body, an ejector pin, and a screw; the first segment plate ejector mechanism main body is provided with spring holes, thimble countersunk holes, and a screw tapping hole; the spring holes are provided with springs; the thimble countersunk hole is provided with a stub bar cut-off thimble; the center of the second segment plate ejector mechanism main body is provided with a screw through hole; the ejector pin is provided with a screw countersunk hole; the ejector pin and the second segment plate ejector mechanism main body are penetrated by the screw, and the screw is immobilized in the screw tapping hole of the first segment plate ejector mechanism main body. Compared with existing technology, the novel keycap in-mould ejector cut-off mechanism possesses following advantages: 50% of manpower used for keycap trimming can be saved; non-defective product yield is increased 20%; stub bars and finished products are separated after mould unloading, so that space of the stub bars is reduced; the finished products can be sucked by mechanical arms directly, combination of the mechanical arms with other devices can be realized, and higher output efficiency is achieved because of the novel keycap in-mould ejector cut-off mechanism.
Description
Technical field
The present invention relates to eject shut-off mechanism in a kind of novel key hat cone.
Background technology
At present; notebook keycap all uses Shooting Technique to produce; when product injection moulding is produced, its glue-feeder can be connected with product; after being all to produce product, conventional machining process use scissors glue-feeder to be cut off and used knife finishing; therefore labor intensive is more; and often can cut up finished product because cutting a material mouthful action, cause fraction defective higher.There is pin mark charging to make product and the technology of entering glue point and separating though at present technical, but because of pin mark glue-feeder very little, be only applicable to smallclothes product, easily occur to shrink or fill with the situation of insatiable hunger as use pin mark chargings such as space bar keycaps for large part product, under current technology, large part injection moulded products use large glue-feeder be still must sample selection.Under existing Shooting Technique; large part injection moulded products is all to use scissors glue-feeder to be cut off and used knife finishing after producing product; therefore work consuming is consuming time; and often can cut up finished product because cutting a material mouthful action; cause fraction defective higher; more need more full inspection personnel to carry out full inspection action, do not meet economic benefit.
Summary of the invention
The present invention, in order to solve the above-mentioned deficiency of prior art, provides in a kind of novel key hat cone and has ejected shut-off mechanism.
Above-mentioned purpose of the present invention realizes by following technical scheme: in a kind of novel key hat cone, eject shut-off mechanism, it is characterized in that: comprise one section of plate ejecting structure body, two sections of plate ejecting structure bodies, knock pin and screw, described one section of plate ejecting structure body is provided with spring eye, hole, the thimble top of city wall and screw tapping hole, in described spring eye, be provided with spring, in hole, the thimble top of city wall, be provided with stub bar and cut off thimble, described two sections of plate ejecting structure body centers are provided with screw perforation, described knock pin is provided with hole, the screw top of city wall, described screw is locked in the screw tapping hole of one section of plate ejecting structure body through knock pin and two sections of plate ejecting structure bodies.
Described stub bar cuts off thimble and can cut off ahead of time than the thimble of one section of plate ejecting structure body and two sections of plate ejecting structure bodies, and product and stub bar and can separate after die sinking, need not use cutter cut out.
Compared with prior art, the present invention has the following advantages: can save keycap and prune manpower approximately 50%, improve non-defective unit ratio approximately 20%, and because stub bar separates after die sinking with product, deducted the space of stub bar; By ejecting structure in keycap mould, manipulator can directly be drawn finished product and do and coordinate with other device, reaches higher output efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail:
As Fig. 1, shown in Fig. 2, in a kind of novel key hat cone, eject shut-off mechanism, it is characterized in that: comprise one section of plate ejecting structure body 1, two sections of plate ejecting structure bodies 2, knock pin 3 and screw 4, described one section of plate ejecting structure body 1 is provided with spring eye 11, hole, the thimble top of city wall 12 and screw tapping hole 13, in described spring eye 11, be provided with spring 5, in hole, the thimble top of city wall 12, be provided with stub bar and cut off thimble 6, described two sections of plate ejecting structure body 2 centers are provided with screw perforation 7, described knock pin 3 is provided with hole, the screw top of city wall 8, described screw 4 is locked in the screw tapping hole 13 of one section of plate ejecting structure body 1 through knock pin 3 and two sections of plate ejecting structure bodies 2.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
