Description
Technical field
The present invention relates to mould applications, especially a kind of guide frame for jacking block connecting rod, are suitable for injection mold.
Background technology
It is developed rapidly at this stage in mould industry, is attempted to create relatively reliable, significantly more efficient mould structure, energy
It enough realizes the smooth demoulding of product, while reducing the defect of product to greatest extent.Jacking block be in mold design frequency of use compared with
High structure.The use of jacking block so that mould structure is more abundant, and mold more tends to high-endization.
Common mandril there are processing difficulties, manufacturing procedure is complicated, expends working hour, jogger hole is easy eccentric and then leads when line is cut
The problems such as causing product there are two or more pieces jacking block line and mandril easy pluckings, to affect the mold process-cycle, mandril makes
With service life, or even influence product quality.
Invention content
In order to solve the above technical problems, the present invention provides a kind of guide frame for jacking block connecting rod.
To achieve the above object, the present invention uses following technical proposals：
A kind of guide frame for jacking block connecting rod, it includes jacking block ontology, clamp spring, guide sleeve and mandril, the head of mandril
Portion is equipped with jacking block ontology；It is faced directly equipped with one in the installation region of jacking block ontology on the head of mandril；The front end sleeve of mandril is equipped with
Guide sleeve；Guide sleeve passes through the clamp spring compression positioned at its head.
Further, the material of guide sleeve is copper and carbon alloy.
Further, the ejector retainner plate of the tail portion of mandril and injection molding machine coordinates, and is faced directly equipped with one in the mating area.
Further, the head of mandril is fastened with jacking block ontology by the first screw.
Further, the ejector retainner plate of the tail portion of mandril and injection molding machine is fastened by the second screw.
Advantageous effect：
1. the present invention is followed ejector retainner plate to move, does guiding role using guide sleeve, pushed down using clamp spring in die sinking moment, mandril
The material of guide sleeve, guide sleeve is copper and carbon alloy, plays the role of lubrication, and avoid mandril plucking, improves mandril service life, simultaneously
Reduce leads to have the defects of a plurality of jacking block line on product because of mandril bias, to improve injecting products quality.
2. process of the present invention is simple, easy replacement easy to process, parts quality is high, can control cost well, be applicable in
Property it is wide, while reducing the component processing time, reduce the mold process-cycle.

Specific implementation mode
Present invention will be further explained below with reference to the attached drawings and examples.
The present embodiment proposes a kind of guide frame for jacking block connecting rod, as shown in Figure 1, it includes jacking block ontology 1,
One screw 2, clamp spring 3, guide sleeve 4, mandril 5 and the second screw 6, the head of mandril 5 are equipped with jacking block ontology 1, pass through the first screw 2
Fastening；It is faced directly equipped with one in the installation region of jacking block ontology 1 on the head of mandril 5；The front end sleeve of mandril 5 is equipped with guide sleeve 4；Guide sleeve
4 pass through the compression of clamp spring 3 positioned at its head.
As shown in Figure 2,3, mandril 5 be located at equal empty avoiding in mavable module core 8, the tail portion of mandril 5 and the Ejector Retainer Plate 9 of injection molding machine and
Thimble panel 10 coordinates, and is fastened by the second screw 6, and the tail portion of mandril 5 is equipped with always in the mating area of Ejector Retainer Plate 9
Face.
In the present embodiment, 5 head of mandril is faced directly in the installation region of jacking block ontology 1 equipped with one, plays the role of rotation stop,
Prevent the rotation in jacking block ontology 1 of mandril 5；The front end of mandril 5 is fitted closely with 4 mating surface of guide sleeve, and guide sleeve 4 plays guiding and makees
With, and can effectively prevent mandril 5 and shaken in mavable module core 8 and jacking block ontology 1 is made to generate two or more pieces jacking block on product 11
Line；Guide sleeve 4 is highly generally 25mm-30mm, thickness 3.5mm-4.5mm, and specific size is adjusted according to mould structure, and material is
Copper and carbon alloy can also play lubricating action while ensureing its hardness, prevent 5 plucking of mandril.Clamp spring 3 is located at the head of guide sleeve 4
Portion plays the role of compressing guide sleeve 4, prevents guide sleeve 4 from moving up and down.It is equipped in the tail portion of mandril 5 and the mating area of Ejector Retainer Plate 9
One faces directly, plays the role of rotation stop.
Moment is molded in mold, since by injection molding machine ejecting force, thimble panel 10 pushes the top of the present embodiment guide frame
Bar 5 is moved along depanning direction, and mandril 5 pushes jacking block ontology 1 that fixed mold core 7 is lifted off mavable module core 8, the shape after entire mold die sinking
State is as shown in Figure 3；In the case where force effect is moved back on injection molding machine top, mandril 5 is moved with thimble panel 10, makes 1 homing of jacking block ontology,
Mold clamping later, entire mold also return to molding state as shown in Fig. 2, preparing to start injection moulding process next time.
Limiting the scope of the invention, those skilled in the art should understand that, in technical scheme of the present invention
On the basis of, the various modifications or variations that can be made by those skilled in the art with little creative work still the present invention's
Within protection domain.
