Abstract

The utility model provides a replaceable thimble subassembly for an injection molding machine, comprising a thimble plate and a plurality of thimbles which are arranged between the thimble plate and a mould cavity; the replaceable thimble subassembly further comprises a plurality of push rods, wherein one ends of the plurality of the thimbles are fixedly installed on the thimble plate and the other ends of the plurality of the thimbles are externally provided with springs and stretch into the mould cavity; and one ends of the plurality of the push rods are clamped at one side of the mould cavity and the other ends of the plurality of the push rods penetrate through the mould cavity to stretch outwards and be locked on the thimble plate. According to the utility model, the thimbles can be freely detached and installed conveniently and rapidly; the thimbles can be guided by the push rods so that the material ejection effect is excellent; meanwhile, the springs are additionally arranged on the thimbles so that the thimbles can be rapidly retracted after being pushed out, and the occupied space can be better saved when the detached thimble components are stored.

Description

The replaceable thimble assembly that a kind of injection machine is used

Technical field

The utility model relates to the technical field of injection machine thimble assembly, refers in particular to the replaceable thimble assembly that a kind of injection machine is used.

Background technology

Convention in the industry; Traditional thimble assembly that is used for injection machine generally adopts monolithic construction, and thimble and mold cavity are difficult for taking apart, and can only be used for and its mold matched die cavity; Such design makes that the placement space of thimble assembly is big; Waste factory building space, and sometimes because thimble different in size regulated also inconvenient.

Summary of the invention

The purpose of the utility model is to overcome the deficiency of prior art, and the replaceable thimble assembly that good, the public property of a kind of liftout effect is strong, the injection machine of thimble ability fast assembling-disassembling is used is provided.

For realizing above-mentioned purpose; The technical scheme that the utility model provided is: the replaceable thimble assembly that a kind of injection machine is used; It includes ejector retainner plate and is located at many thimbles between this ejector retainner plate and the mold cavity, and it also includes many push rods, wherein; One end of many thimbles is fixedly mounted on the ejector retainner plate, and its other end is added with spring outward and puts in the mold cavity; One end of many push rods is stuck in a side of mold cavity, and its other end passes this mold cavity and stretches out outward and be locked on the ejector retainner plate.

The utility model is after having adopted such scheme; Its great advantage is that the thimble of the utility model can freely remove and install; Convenient and swift, and through push rod thimble is led, make its liftout effect good; Add on the thimble simultaneously and can return fast after spring pushs out it, can save well when the thimble assembly after the dismounting is deposited in addition and take up an area of the space.

The specific embodiment

Below in conjunction with specific embodiment the utility model is further specified.

Shown in accompanying drawing 1 and accompanying drawing 2; The replaceable thimble assembly that the described injection machine of present embodiment is used; Include ejector retainner plate 1 and be located at the many thimbles 2 between this ejector retainner plate 1 and the mold cavity 5, many push rods 3, wherein; One end of many thimbles 2 is fixedly mounted on the ejector retainner plate 1, and its other end is added with spring 4 outward and puts in the mold cavity 5; One end of many push rods 3 is stuck in a side of mold cavity 5, and its other end passes this mold cavity 5 and stretches out outward and be locked on the ejector retainner plate 1.Such design makes the thimble 2 of the utility model freely to remove and install, and is convenient and swift, and leads through 3 pairs of thimbles 2 of push rod; Make its liftout effect good; Simultaneously since on thimble 2 outer being added with can return fast after spring 4 pushs out it, stable action is reliable, can dismantle fully when the utility model is deposited in addition and deposit; Save well and take up an area of the space, be worthy to be popularized.

The embodiment of the above is the preferred embodiment of the utility model only, is not the practical range that limits the utility model with this, so the variation that all shapes according to the utility model, principle are done all should be encompassed in the protection domain of the utility model.

Claims
