Background

Molds are tools used to make shaped articles, and the development level of mold production is one of the important signs of the machine manufacturing level. At present, medical supplies such as needle bases, sheaths, insulin shells and the like are generally manufactured by adopting a multi-runner injection mold.

For example, chinese patent literature discloses a multi-runner injection mold [ application number: 201922493006.8; authorization notice number: CN211542205U ], it includes the die holder, the cope match-plate pattern, the lower bolster, go up mould benevolence and lower mould benevolence, it is upper, the lower bolster is located respectively in the lower die holder, it is upper, the lower mould benevolence is located respectively in the lower bolster, form a plurality of die cavities of moulding plastics after going up mould benevolence and lower mould benevolence compound die, every die cavity of moulding plastics all communicates a runner of moulding plastics alone, be provided with the runner hot plate between cope match-plate pattern and the cope match-plate pattern, the embedded heating wire that is equipped with many and set up around the runner of moulding plastics of runner, many heating wires can the independent control heating temperature.

Above-mentioned multithread way mould has improved the effect of moulding plastics through the setting of runner hot plate and heating wire, but it is the same with other moulds of current, behind the die sinking, has the difficult problem that drops of waste material, and this is because the adhesive force of waste material is big, and the power that drives the waste material and drop is less, and the waste material can not drop and lead to the fact the card material, must get rid of the waste material, and the mould begins work again, influences machining efficiency.

Disclosure of Invention

The utility model aims at providing a waste material drops smoothly, can not block the mould of material and takes off material device to the above-mentioned problem that exists among the prior art.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a material device is taken off to mould, is including being massive template, the template on have a plurality of and link up the perforating hole of its top surface and bottom surface, its characterized in that, the perforating hole in link firmly the mount pad, the top surface of mount pad and the top surface of template flush, the mount pad has circumference equipartition and link up the die cavity of its top surface, the mount pad in wear to be equipped with the slide bar rather than coaxial setting, the top of slide bar the fender shoulder that radially evaginates has, slide bar and mount pad between be equipped with and supply to keep off the shoulder to support and lean on the piece, conflict when supporting and lean on the piece, keep off the top surface of shoulder and flush in the top surface of mount pad, the bottom of slide bar link firmly and block the piece, slide bar and mount pad between be equipped with the spring, the spring provide elasticity and make to block the tendency that has contradicted in the tendency of mount pad, slide bar and keep moving outward to its top.

In foretell mould takes off material device, support to lean on the piece to be the tube-shape and supply the slide bar to pass, support to support the top surface of piece to supply to keep off the shoulder and support and lean on, support to lean on the piece and offer the mounting groove that supplies spring mounting, the lower extreme of spring is contradicted in the tank bottom of mounting groove, the upper end of spring is contradicted in keeping off the shoulder.

In foretell mould takes off material device, the outside edge that supports to lean on the piece have radial evagination and lie in and keep off the chimb between shoulder and the mount pad, the top surface of chimb flushes in the top surface of mount pad, the inner wall of chimb has two sections conical surfaces to constitute so that the chimb inner wall is the flaring form, keeps off the lateral wall and the diapire of shoulder for the adaptation in the binding face of the two conical surfaces of chimb.

In the above mold stripping device, the blocking member is a cylindrical stopper, the outer diameter of the stopper is larger than that of the sliding rod, a bolt penetrates through the stopper and is in threaded connection with the sliding rod, and the inner wall of the stopper is provided with a step for abutting against the head of the bolt.

As another aspect, in the above mold stripping device, the blocking member is a nut screwed to the bottom end of the sliding rod. The nut is contradicted in the mount pad, avoids the slide bar to break away from the mount pad, and the nut is adjustable in position on the slide bar, can conveniently adjust the distance that the mount pad was stretched out on the slide bar top, and the accurate location of being convenient for, the waste material process is released to the slide bar in time, smoothly.

In the above mold stripping device, the lower portion of the mounting seat has a radially outward protruding protrusion, the inner wall of the through hole has a shoulder against which the protrusion abuts, and a plurality of screws pass through the protrusion and are screwed to the mold plate.

Compared with the prior art, the die stripping device is convenient to install, good in working stability, capable of enabling waste materials to drop smoothly, free of material clamping and high in machining efficiency.
