Abstract
The utility model discloses a flexible cover pull rod structure moulds plastics, it belongs to the injection mold field, and it has solved and has lacked a simple structure among the prior art, and the suitability is strong, adopts flexible cover and pull rod structure, shortens the shaping cycle, with low costs and the efficient flexible cover pull rod structure's of moulding plastics problem. The fixed die mainly comprises a movable die and a fixed die, wherein a telescopic sleeve fixing seat is arranged on the fixed die, and a telescopic sleeve is fixed on the telescopic sleeve fixing seat; and an upper ejector plate and a lower ejector plate are arranged on the movable die, and pull rods are fixed on the upper ejector plate and the lower ejector plate. The utility model discloses mainly used solves the unable drawing of patterns of long piece of moulding, and the unable whole ejecting product of injection molding machine top rod stroke.
Description
Technical Field
The utility model relates to an injection mold, specifically speaking especially relates to a flexible cover pull rod structure moulds plastics.
Background
The demolding of common short parts is convenient, but the demolding is inconvenient when the injection molding part is longer, the long part cannot be demolded in the past, the stroke of the ejection roller of the injection molding machine cannot be completely ejected, and the existing injection mold cannot meet the molding requirement of the long plastic part. The oil cylinder can be used for assisting ejection, but the oil cylinder assisting ejection mode is high in cost, the oil cylinder and the ejection rod are used for shortening the forming period, the efficiency is low, and the stability of the oil cylinder is poor.
At present, a telescopic sleeve pull rod structure which is simple in structure, high in applicability, low in cost and high in efficiency and shortens the forming period by adopting a telescopic sleeve and a pull rod structure is lacking.
Disclosure of Invention
The utility model aims at providing a telescopic sleeve pull rod structure moulds plastics to solve and lack a simple structure among the prior art, the suitability is strong, adopts telescopic sleeve and pull rod structure, shortens the shaping cycle, with low costs and the efficient telescopic sleeve pull rod structure's of moulding plastics problem.
The utility model discloses a realize through following technical scheme:
a telescopic sleeve pull rod structure for injection molding comprises a movable mold and a fixed mold, wherein a telescopic sleeve fixing seat is arranged on the fixed mold, and a telescopic sleeve is fixed on the telescopic sleeve fixing seat; and an upper ejector plate and a lower ejector plate are arranged on the movable die, and pull rods are fixed on the upper ejector plate and the lower ejector plate.
Furthermore, the telescopic sleeve is fixed on the telescopic sleeve fixing seat through a headless screw.
Furthermore, the telescopic sleeve is divided into a telescopic outer sleeve and a telescopic inner sleeve, and the telescopic outer sleeve is internally provided with the telescopic inner sleeve.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the ejection mechanism has the advantages of simple structure and strong applicability, and effectively solves the problems of ejection without a top rod and ejection with a large stroke by adopting a telescopic sleeve and a pull rod structure.
2. Avoid using hydro-cylinder and top rod, greatly shortened the shaping cycle, improved the stability when the drawing of patterns, satisfy the full-automatic ejecting of high spare.
3. The pull rod and the telescopic sleeve can be replaced according to the heights of different molds, and the applicability is strong.
Drawings
FIG. 1 is a schematic structural diagram I of the present invention;
FIG. 2 is a schematic structural diagram II of the present invention;
fig. 3 is a schematic structural view of the telescopic sleeve of the present invention.
In the figure: 1. a pull rod; 2. a telescopic sleeve; 3. a telescopic outer sleeve; 4. a telescopic inner sleeve; 5. an upper ejector plate; 6. a lower ejector plate; 7. a telescopic sleeve fixing seat; 8. headless screws.
Detailed Description
The invention will be further described and illustrated with reference to the accompanying drawings.
Embodiment 1, an injection molding telescopic sleeve pull rod structure, comprising a movable mold and a fixed mold, wherein the fixed mold is provided with a telescopic sleeve fixing seat 7, and a telescopic sleeve 2 is fixed on the telescopic sleeve fixing seat 7; an upper ejector plate 5 and a lower ejector plate 6 are arranged on the movable die, and pull rods 1 are fixed on the upper ejector plate 5 and the lower ejector plate 6.
Embodiment 2, an injection molding telescopic sleeve pull rod structure, the telescopic sleeve 2 is fixed on a telescopic sleeve fixing seat 7 through a headless screw 8; the telescopic sleeve 2 is divided into a telescopic outer sleeve 3 and a telescopic inner sleeve 4, the telescopic inner sleeve 4 is arranged in the telescopic outer sleeve 3, and the rest is the same as that of the embodiment 1.
The telescopic sleeve 2 is divided into a telescopic outer sleeve 3 and a telescopic inner sleeve 4, the stretching depth can be fixed according to the product length and the die sinking stroke, one end of the pull rod 1 passes through the telescopic sleeve fixing seat 7 after die sinking, and the other end of the pull rod is fixed through the upper ejector plate 5 and the lower ejector plate 6 to pull the upper ejector plate 5 and the lower ejector plate 6 and push the ejector pins to eject the product.
