Abstract
The invention discloses a back needle withdrawing mechanism comprising a bracket, a back needle and a screw, wherein the bracket is locked in a lower die core; the back needle is mounted on an ejector pin panel; the screw is locked in the back needle, and penetrates the bracket; a mold insert with an internal thread is sleeved on the screw; an thread matched with the thread in the mold insert is arranged on the screw; and a handle driving the mold insert to rotate is arranged on the mold insert. As the back needle withdrawing mechanism is mounted on a lower mold plate to ensure enough operation space and effortless operation, the ejector pin panel can be lifted up cushily to reserve a mounting space for an inclined roof seat.
Description
Technical field
The present invention relates to a kind of back stitching and retract mechanism, belong to plastic mould and make the field.
Background technology
In the middle of the mould design,, insert tiltedly and must tilted footstock be installed so that at this moment fixing tiltedly top need install from thimble panel top behind the top because the requirement of this body structure of product needs utilization tiltedly to eject product usually.Lock screw again, thereby need elder generation with the pull-up of thimble panel, the installation tilted footstock just has living space; In the middle of the method for existing installation tilted footstock, also often utilize locking pliers or lock plug to screw from the panel bottom, relatively heavier with the method for locking pliers, must use very big power during operation; And manually-operated has certain danger, locks the method that plug screws from the thimble panel, mainly is need turn plug with spanner to screw; Fill in the compressing thimble panel that screws and move upward, thereby reserve the space, yet the defective of this method is that mainly spanner is when operation; Too little through regular meeting because of the distance between two square iron, the operation of inconvenient spanner.
Summary of the invention
To the deficiency of prior art, the object of the present invention is to provide a kind of back stitching to retract mechanism, back stitching is up spurred, drive the thimble panel and up move, thereby reserve the tilted footstock installing space, so that tilted footstock is installed.
For realizing above-mentioned purpose; Technical scheme of the present invention is: a kind of back stitching retracts mechanism; Comprise the support of locking down die, be installed on the back stitching on the thimble panel and lock the screw rod of back stitching, it is characterized in that: described screw rod passes said support, on described screw rod, is with the mold insert that an inside has screw thread; Described screw rod is provided with the screw thread with the inner threads engaged of said mold insert, and said mold insert is provided with and drives the handle that mold insert rotates.
Aforesaid back stitching retracts mechanism, it is characterized in that: between said mold insert and said support, be provided with packing ring.
Aforesaid back stitching retracts mechanism, it is characterized in that: described back stitching and screw rod junction are provided with securing member.
The invention has the beneficial effects as follows: this tool is installed on the lower bolster, enough operating spaces are arranged on lower bolster, and operate leicht fallen D/A, easily the thimble panel is mentioned, thereby reserve the installing space of tilted footstock.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
For further disclosing technical scheme of the present invention; Be described with reference to the accompanying drawings embodiment of the present invention: as shown in Figure 1 at present; A kind of back stitching retracts mechanism; Comprise the support 1 of locking down die, be installed on the back stitching 2 on the thimble panel and lock the screw rod 3 of back stitching 2, back stitching 2 is provided with securing member 4 with screw rod 3 junctions.Screw rod 3 passes support 1, on screw rod 3, is with the mold insert 5 that an inside has screw thread, and screw rod 3 is provided with the screw thread with the inner threads engaged of mold insert 5, and mold insert 5 is provided with and drives the handle 6 that mold insert 5 rotates.Between mold insert 5 and support 1, be provided with packing ring 7, make the connection between mold insert 5 and the support 1 tightr.
Basic principle of the present invention is: through fixed support 1 with screw rod 3; And threaded mold insert 5 is fixing with packing ring 7; And handle 6 is installed on the threaded mold insert 5, turns threaded mold insert 5 through handle 6, screw rod 3 and mold insert 5 cooperate through between screw thread and the screw thread; Make it to drive screw rod 3 and up move, up move thereby carrying back stitching 2 drive thimble panels.
More than, basic design of the present invention and basic principle have been set forth through introduction to listed embodiment.But the present invention never is limited to above-mentioned listed embodiment, and every equivalent variations, improvement and deliberately of inferior quality behavior of doing based on technical scheme of the present invention of change all should belong to protection scope of the present invention.
