Abstract

The utility model provides a segmental push rod, belonging to the technical field of machinery. The segmental push rod solves the problems of lower applicability and high cost of the current push rod. The segmental push rod comprises a body, wherein the body comprises a thrust part and a force application part, the thrust part is sheathed into a push plate fixing plate, and the force application part is axially fixedly connected with the thrust part and extends into a mold cavity. The segmental push rod comprises the thrust part and the force application part, the thrust part can be processed into a standard element to be convenient for standardized production, and the force application part is designed into different shapes and specifications according to different demoulding requirements of different products. According to the demands, the force application part can be made of different materials. The segmental push rod has the advantages of simple structure and low manufacturing cost.

Description

A kind of segmented push rod
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of injection mold, particularly the push rod in a kind of injection mold.
Background technology
Injection mold is plastic injection moulding process tooling device used, and it is mainly used in molded thermoplastic plastic products.Injection mold is comprised of dynamic model and cover half two large divisions; dynamic model is arranged on the moving platen of injector; cover half is arranged on the solid plate of injector; moving before injection, cover half closure under injector drives, form die cavity and running gate system, and injector is all that plastic melt injects die cavity by running gate system by plastifying; after cooled and solidified; moving, cover half is opened, and mould emptier is released plastic cement, completes the injection moulding action of a workpiece.
Mould emptier of the prior art generally adopts thimble or push rod; and ejector pin retaining plate supporting with it, push pedal, ejector guide pillar, push pedal guide pillar, release link, sprue puller etc.; push rod of the prior art is generally standard component, selects the push rod of different size according to workpiece size.But push rod of the prior art is owing to adopting standard component, its planform is fixed, for the comparatively complicated product of some structures, it adopts standard push rod to be difficult to the stripping result that reaches good, therefore need to make special push rod, according to product stripping position, knockout press, demoulding angle, calculate, push rod is redesigned.And the actual site of action of push rod is only to stretch into the position that die cavity contacts with shaped article, if push rod entirety redesigns, certainly will propose higher requirement to the processing of push rod, and cost is also higher.Be unfavorable for industrialized development.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of segmented push rod, and the generalization that had both met push rod is produced, and meets again the customization structural requirement of push rod.
The purpose of this utility model can realize by following technical proposal: a kind of segmented push rod, comprise body, it is characterized in that, described body comprises the thrust portion being sheathed in push pedal fixed head and the force section being connected with thrust portion axial restraint, and described force section is stretched in mold cavity.
In above-mentioned segmented push rod, described thrust portion end is provided with storage tank, in described storage tank, be provided with spacing cavity, described end, force section is provided with positive stop lug boss and the described interior rear described positive stop lug boss of end, force section insertion storage tank can embed in above-mentioned spacing cavity.
As another kind of scheme, in above-mentioned segmented push rod, described thrust portion end is provided with positive stop lug boss, described thrust portion outside is arranged with the cap that is threaded, the described cap inner side that is threaded has the flange that can be resisted against on positive stop lug boss, and described force section end is provided with and can be socketed on the external screw thread being threaded on cap.
In above-mentioned segmented push rod, on described force section, there is the force surface matching with workpiece inner face.
Compared with prior art, this segmented push rod comprises thrust portion and force section, thrust portion can be processed into standard component and facilitate standardized production, force section can require design to be difformity and specification according to the different demouldings of different product, as required, also can adopt different materials make force section, possess simple in structure, the advantage of low cost of manufacture.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of this segmented push rod;
Fig. 2 is the perspective view of this segmented push rod.
In figure, 1 body; 2, thrust portion; 3, force section; 4, storage tank; 5, spacing cavity; 6, positive stop lug boss; 7, force surface.
The specific embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As depicted in figs. 1 and 2, this segmented push rod, comprises push rod body 1, and described push rod body 1 comprises the thrust portion 2 being sheathed in push pedal fixed head and the force section 3 being connected with thrust portion 2 axial restraints, and described force section 3 is stretched in mold cavity.Thrust portion 1 end is provided with storage tank 4, is provided with spacing cavity 5 in described storage tank 4, and described 3 ends, force section are provided with positive stop lug boss 6 and the described force section interior rear described positive stop lug boss 6 of 3 ends insertion storage tank 4 can embed in above-mentioned spacing cavity 5.On force section 3, there is the force surface 7 matching with workpiece inner face, for top, be pressed in and on workpiece, carry out the demoulding.
This push rod is for being arranged on the mould emptier of mould; the thrust portion 2 of push rod is located on push pedal fixed head; the bottom of push rod is resisted against in push pedal, the thrust portion 2 of push pedal and force section 3 separate machined, and thrust portion 2 can be used as standard component and processes; force section 3 can be according to the demoulding requirement of shaping workpiece; structure, intensity and the material behavior of change force section, the personalized customization of conveniently stripped mechanism, possesses applicability wide; cost is low, the good advantage of stripping result after using.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
