Abstract
A threaded mold dismounting device for injection molding parts comprises a fixing frame, wherein the fixing frame comprises a bottom plate and a top plate which are parallel to each other and arranged at intervals, a mounting groove is formed in the bottom plate, a jacking block is movably arranged in the mounting groove, a threaded hole is formed in the bottom plate, a jacking rod capable of jacking the jacking block is arranged in the threaded hole, and an external thread matched with the threaded hole and a crank driving the jacking rod to rotate are arranged on the jacking rod; the dismounting device also comprises a chuck which is matched with the top block and can clamp the injection molding piece, a through hole which is matched with the outer diameter of the thread mould is arranged on the chuck, and a step which can be clamped into the U-shaped bayonet is arranged at the edge of the chuck; the injection molding piece is clamped tightly through the cooperation of the chuck and the ejector block, the U-shaped bayonet prevents the chuck from rotating, the threaded mold can rotate freely in the chuck through hole, the threaded mold can be detached only by rotating the threaded mold, the threaded mold can rotate freely in the chuck through hole, and the detaching device is simple in structure and convenient to operate.
Description
Technical Field
The utility model relates to an injection molding mould extracting tool.
Background
The threaded mold is arranged on injection molding parts with large inner diameters and internal threads, after injection molding is completed, the threaded mold is screwed out after the injection molding parts are cooled to form threads on the injection molding parts, but due to the reasons of expansion with heat and contraction with cold, the injection molding parts are more tightly combined with the threaded mold after being cooled, and are difficult to be screwed out manually, so that special disassembling tools are needed to disassemble.
Disclosure of Invention
In order to solve the deficiencies in the prior art, the utility model provides a simple structure dismantles convenient laborsaving dismounting device, the utility model discloses the technical scheme who adopts is:
a threaded mold dismounting device for injection molding parts comprises a fixing frame, wherein the fixing frame comprises a bottom plate and a top plate which are parallel to each other and arranged at intervals, a mounting groove is formed in the bottom plate, a top block is movably arranged in the mounting groove, a threaded hole is formed in the bottom plate, a top rod capable of jacking the top block is arranged in the threaded hole, and an external thread matched with the threaded hole and a crank for driving the top rod to rotate are arranged on the top rod; the ejector plate on be equipped with U type bayonet socket, this dismounting device still including with the kicking block cooperation can be with the chuck that the injection molding was cliied the chuck on be equipped with the through-hole that matches with the screw thread mould external diameter the chuck edge be equipped with the step that can block into U type bayonet socket.
Furthermore, a rubber gasket is arranged on the top block.
Adopt the extracting tool of above-mentioned structure, press from both sides the injection molding tightly through chuck and kicking block cooperation, U type bayonet socket prevents that the chuck from rotating, and the screw thread mould can free rotation in arranging the chuck through-hole in, only need rotate the screw thread mould and can demolish it, and the screw thread mould can free rotation in arranging the chuck through-hole in, this dismounting device simple structure, convenient operation.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is an exploded view of the present invention.
Detailed Description
As shown in fig. 1 and fig. 2 dismounting device includes the mount, this mount includes bottom plate 1 and roof 2 that a pair of interval set up and be parallel to each other, be equipped with mounting groove 3 on bottom plate 1, be equipped with kicking block 4 in the mounting groove 3, kicking block 4 activity sets up and can go up and down in mounting groove 3, still be equipped with screw hole 5 on bottom plate 1, be equipped with ejector pin 6 in screw hole 5, be equipped with the external screw thread with screw hole 5 complex on ejector pin 6, still be equipped with crank 7 on ejector pin 6, make ejector pin 6 remove along screw hole 5 and come the lifting or reduce kicking block 4 through rocking crank 7, wherein screw hole 5 is arranged in mounting groove 3 center best, make ejector pin 6 balanced to kicking block 4's effort like this, mounting groove 3 can play the guide effect when kicking block 4 lifting or reducing and prevent kicking. Still be equipped with chuck 9 in the device, it can supply thread mould B to pass and can block injection molding A again to be equipped with through-hole 10 on chuck 9, still be equipped with step 11 at chuck 9 edge, be equipped with U type bayonet socket 8 on roof 2, step 11 card is in U type bayonet socket 8 department, press from both sides injection molding A tightly between chuck 9 after kicking block 4 is lifted, generally can be provided with interior hexagonal hole on thread mould B, it is its drawing of patterns through the rotatory thread mould of hexagonal spanner, and step 11 can block and rotate along with the mould at drawing of patterns in-process chuck 9, rotatory ejector pin 6 reduces kicking block 4 after the drawing of patterns is accomplished, take out chuck 9 intercommunication injection molding and thread mould. During installation, the threaded mold B is firstly inserted into the through hole, then the chuck 9 is communicated with the threaded mold and the injection molding piece is pushed into the U-shaped bayonet 8, the ejector rod 6 is rotated to enable the ejector block to rise too high to clamp the injection molding piece A, and then the threaded mold can be disassembled.
In order to avoid scratching the surface of the injection molding part A when the ejector block 4 clamps the injection molding part A, and simultaneously improve the friction coefficient of the injection molding part A, so that the threaded mold B can be conveniently screwed and taken out, the rubber gasket 12 in contact with the injection molding part A is arranged on the ejector block 4.
