Abstract
The utility model discloses a kind of parent form structure, including parent form housing and mold core, and parent form housing is sheathed on mold core lateral wall, boss is arranged with outside parent form, boss surround setting along the lateral wall of parent form housing, it is characterised in that, boss is equipped with gas pressure relief slot, side surrounding of the gas pressure relief slot along boss.Gas pressure relief slot is opened up by the side outward facing sides in parent form housing, the pretightning force born except mold core is suitably let out, avoids mold core from bursting apart, prolong its service life, structure is simple, practical reliable.
Description
Technical field
The utility model relates to the parent form technical fields of powder metallurgy die, and in particular, to a kind of parent form structure.
Background technique
Parent form is also known as former, generally comprises parent form housing and mold core, when processing parent form with Powder metallurgic forming machines, usually
It is required that mold core high rigidity and wear-resisting, and mold core cracks in pressing process in order to prevent, and outside can assemble parent form housing, give
Internal mold core pretightning force, to balance the surface tension that mold core is subject in pressing process.Conventional way is to use general structural steel
As parent form housing, internal mold core is wolfram steel, and mold core is attached in parent form housing, needs mold core housing by elastic conjunction (hot charging)
Mold core is embedded in parent form housing by heating using high-temperature heating expansion.After the temperature of parent form housing is down to room temperature, cooling down
During being contracted to normal size, can inwardly it tighten.Since the hardness of mold core is high, so its property is more crisp, and parent form housing
Wall unevenness will lead to mold core receiving contraction dynamics it is uneven, mold core is chronically at operation in the state of unbalance stress, is easy
It bursts apart.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of parent form structure.
A kind of parent form structure disclosed by the utility model, including parent form housing and mold core, parent form housing are sheathed on outside mold core
Side wall, parent form are arranged with boss outside, and boss surround setting along the lateral wall of parent form housing, which is characterized in that boss is equipped with pressure release
Slot, side surrounding of the gas pressure relief slot along boss.
An embodiment according to the present utility model, above-mentioned gas pressure relief slot are V of the horizontal opening towards parent form housing side
Shape slot.
The depth of an embodiment according to the present utility model, above-mentioned V-shaped groove is flushed with the lateral wall of parent form housing.
An embodiment according to the present utility model, above-mentioned V-shaped groove are in symmetrical structure along the horizontal center line of boss.
Compared with prior art, the utility model can be obtained including following technical effect:
Gas pressure relief slot is opened up by the side outward facing sides in parent form housing, the pretightning force born except mold core is suitably let out, avoids mould
Core bursts apart, and prolongs its service life, and structure is simple, practical reliable.
Detailed description of the invention
The drawings described herein are used to provide a further understanding of the present application, constitutes part of this application, this Shen
Illustrative embodiments and their description please are not constituted an undue limitation on the present application for explaining the application.In the accompanying drawings:
Fig. 1 is the diagrammatic cross-section of the parent form structure in embodiment.
Specific embodiment
Multiple embodiments that the utility model will be disclosed with schema below, as clearly stated, in many practices
Details will be explained in the following description.It should be appreciated, however, that the details in these practices does not apply this with limitation practical new
Type.That is, the details in these practices is non-essential in some embodiments of the utility model.In addition, for letter
For the sake of changing schema, some known usual structures and component will be painted it in the drawings in simply illustrative mode.
It is to be appreciated that the directional instruction (such as up, down, left, right, before and after ...) of institute in the utility model embodiment
It is only used for explaining in relative positional relationship, the motion conditions etc. under a certain particular pose (as shown in the picture) between each component, such as
When the fruit particular pose changes, then directionality instruction also correspondingly changes correspondingly.
It in addition, the technical solution between each embodiment can be combined with each other, but must be with ordinary skill
Based on personnel can be realized, this technical side will be understood that when the combination of technical solution appearance is conflicting or cannot achieve
The combination of case is not present, also not within the protection scope of the requires of the utility model.
Referring to Fig. 1, its diagrammatic cross-section for the parent form structure in the present embodiment；As shown, in the present embodiment
The overall structure of parent form structure is cylinder, and parent form structure includes parent form housing 1 and mold core 2, and parent form housing 1 is sheathed on mold core 2
Lateral wall.Wherein the lateral wall of parent form housing 1 is equipped with boss 11, and boss 11 rounds along its lateral wall.
Further, boss 11 is equipped with gas pressure relief slot 111, side surrounding one week along boss 11 of gas pressure relief slot 111, gas pressure relief slot
111 notch is towards the side of parent form housing 1.Preferably, the shape of gas pressure relief slot 111 is horizontal V-shaped groove A, the edge of V-shaped groove A
The most deep depth of horizontal direction is extended to be flushed with the lateral wall of parent form housing 1, and groove body is avoided to extend to parent form housing 1
In main body, to influence the intensity of 1 main body of parent form housing, while by horizontal V-shaped groove A as draining hole by internal pressure
Power suitably draws alleviation.Preferably, V-shaped groove A is in symmetrical structure along the horizontal center line of boss, to more equably alleviate female
The pretightning force that type housing 1 is inwardly tightened when cooling alleviates the pretightning force that mold core 2 is born, so that mold core 2 be avoided to burst apart.
In conclusion opening up gas pressure relief slot by the side outward facing sides in parent form housing, the preload born except mold core is suitably let out
Power avoids mold core from bursting apart, and prolongs its service life, and structure is simple, practical reliable.
Upper described only the embodiments of the present invention, is not intended to limit the utility model.For this field
For technical staff, various modifications and changes may be made to the present invention.The interior institute of all spirit and principle in the utility model
Any modification, equivalent substitution, improvement and etc. of work should all include within the scope of the claims of the utility model.
