Abstract
The utility model discloses a molding die for a rubber diaphragm, comprising a hotly-pressing convex die and a hotly-pressing concave die, wherein the hotly-pressing convex die is provided with a diaphragm fixing ring which is used for pressing the edge part of the rubber diaphragm. The diaphragm fixing ring is additionally arranged on the hotly-pressing convex die, so that the diaphragm fixing ring is used for automatically pressing the edge part of the rubber diaphragm when the rubber diaphragm is extruded and molded, and the phenomena of raised edges, staggering and retraction of the rubber diaphragm are prevented; and the finished product yield is improved and the product quality is guaranteed.
Description
Technical field
The utility model relates to a kind of mould, especially a kind of mould for the rubber diaphragm moulding.
Background technology
The rubber diaphragm application scenario is very extensive, such as the resilient device in the automobile brake chamber, membrane pump etc.The dimensional accuracy of rubber diaphragm directly affects the serviceability of product, so to producing rubber diaphragm high requirement is arranged in the industry.Adopt conventional mould when producing rubber diaphragm, the rubber diaphragm blank produces dislocation easily, and perhaps the rubber diaphragm blank shrinks in die when extrusion modling, causes the finished product disqualification rate higher, does not also have than good method at present to solve this technical problem.
The utility model content
Problem to be solved in the utility model just provides a kind of mould for rubber diaphragm, can effectively solve the dislocation of rubber diaphragm generation when producing, the technical problem of contraction, improves the quality of products.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of mould for rubber diaphragm, comprise hot pressing punch and hot pressing die, and described hot pressing punch is provided with the zona of deciding of pushing down the rubber diaphragm edge.
Further, describedly decide zona and be connected by spring with described hot pressing punch.
Further, describedly decide zona and described hot pressing punch is connected by screw, the locating hole corresponding with described screw on the described hot pressing die, screw head embeds in the described locating hole when described hot pressing punch and described hot pressing die matched moulds.
The beneficial effects of the utility model: the utility model increases at the hot pressing punch decides zona, when the rubber diaphragm extrusion modling, utilize the edge of deciding zona automatic impaction rubber diaphragm, prevent that the phenomenon of alice, dislocation, contraction from appearring in rubber diaphragm, improve product qualified rate, guarantee product quality.
Description of drawings
Below in conjunction with accompanying drawing the utility model is explained and illustrated:
Fig. 1 is the structural representation of the utility model embodiment one;
Fig. 2 is the structural representation of the utility model embodiment two.
The specific embodiment
The utility model provides a kind of mould for rubber diaphragm, comprises hot pressing punch and hot pressing die, and described hot pressing punch is provided with the zona of deciding of pushing down the rubber diaphragm edge.The pressuring action of deciding zona has been arranged, the phenomenons such as alice, dislocation, contraction can not occur during the rubber diaphragm extrusion modling, improved yield rate.
Be explained and illustrated below in conjunction with the accompanying drawing of the present embodiment technical scheme to the utility model embodiment, but following embodiment is preferred embodiment of the present utility model only, is not whole.Based on the embodiment in the embodiment, those skilled in the art belong to protection domain of the present utility model at lower other embodiment that obtains of the prerequisite of not making creative work.
Embodiment one:
With reference to Fig. 1, a kind of mould for rubber diaphragm comprises hot pressing punch 1 and hot pressing die 2, described hot pressing punch 1 be provided with push down rubber diaphragm 5 edges decide zona 4, decide zona 4 and be connected by spring 3 with described hot pressing punch 1.Hot pressing punch 1 comprises heat-conducting plate 11 and forming convax mould 12, and hot pressing die 2 comprises lower heat-conducting plate 21 and molding concave die 22.During production, forming convax mould 12 is by upper heat-conducting plate 11 heating, molding concave die 22 is by lower heat-conducting plate 21 heating, reach the temperature of technological requirement when moulding punch 12 and molding concave die 22, hot pressing punch 1 and hot pressing die 2 begin to close film, when closing film and beginning, decide the edge that zona 4 props up rubber diaphragm 5 blanks, prevent its alice; After rubber diaphragm 5 blanks are extruded moulding, decide zona 4 and compress rubber diaphragm 5 edges, prevent rubber diaphragm 5 thermotropisms indentation mould 2 internal contraction, and prevented that rubber diaphragm 5 from producing dislocation in mould.
Embodiment two:
With reference to Fig. 2, the difference of present embodiment and embodiment one is: in the present embodiment, deciding zona 4 is connected by screw 6 with described hot pressing punch 1, the locating hole 23 corresponding with described screw 6 on the described hot pressing die 2, screw 6 heads embed in the described locating hole 23 when described hot pressing punch 1 and described hot pressing die 2 matched moulds.Like this, deciding zona 4 can move axially at screw 6, and the locating hole 23 on the hot pressing die 2 is in order to dodge screw 6 on the one hand, on the other hand, by cooperating of locating hole 23 and screw 6, play guide effect, so that mould closes film location is more accurate, reduces mould and interfere.The beneficial effect of present embodiment is not describing in detail with reference to embodiment one.
By above-described embodiment, the purpose of this utility model is by in full force and effect having reached.The personage who is familiar with this skill should be understood that the utility model includes but not limited to the content of describing in accompanying drawing and the top specific embodiment.Any modification that does not depart from function and structure principle of the present utility model all will be included in the scope of claims.
Claims (3)
1. a mould that is used for rubber diaphragm comprises hot pressing punch and hot pressing die, and it is characterized in that: described hot pressing punch is provided with the zona of deciding of pushing down the rubber diaphragm edge.
2. a kind of mould for rubber diaphragm as claimed in claim 1 is characterized in that: describedly decide zona and be connected by spring with described hot pressing punch.
3. a kind of mould for rubber diaphragm as claimed in claim 1, it is characterized in that: describedly decide zona and described hot pressing punch is connected by screw, the locating hole corresponding with described screw on the described hot pressing die, screw head embeds in the described locating hole when described hot pressing punch and described hot pressing die matched moulds.
