Abstract

The utility model relates to molding mould field, especially relates to improvement of button mold core structure. A button mold core structure includes a core body and an inlaid block mounted on thecore body, the shape of the inlaid block is identical to the shape of an inner cavity of a button to be molded, the bottom edge of the inlaid block is provided with a spreading edge projected outwardssuch that the edge of the inner cavity opening of the button after molding is in an chamfer angle or rounded corner; the spreading edge is a continuous heave or discontinuous heave spreading along the bottom edge of the inlaid block. The structural design of the utility model is novel, it is possible to eliminate burs located on the inner cavity edge of the button after molding by setting the spreading edge on the inlaid block bottom, such that the installation and usage of the button are more convenient, and button hand feeling is improved. At the same time, the button mold core structure does not need handwork intervention, such that it is possible to reduce operator number, improve products yield and further reduce production cost.

Description

A kind of button mold insert structure
Technical field
The utility model relates to the mould field, specially refers to the improvement to the button mold insert structure.
Background technology
Under socialist market conditions, " improve quality, raise the efficiency, reduce cost " this target is all being pursued by each manufacturing enterprise.As automobile audio button work flow, also should adapt to the fast-developing market demand.
Be depicted as mold insert structure schematic diagram in the prior art as accompanying drawing 1~2, this mold insert structure comprises core rod and is fixed in inserting on the core rod, insert and be the right angle between bottom margin and the core rod, button after the process core rod and the moulding of inserting is shown in accompanying drawing 3~5, can find out that from figure the accent edge is Li Jiao in the button, burr can appear in the edge, cause when assembling and use, having some setbacks, influence the assembling and the use of button.All be to adopt by hand to know burr generally speaking after button forms out, complex operation, the lost labor, and higher to the manual operator specification requirement, be difficult to guarantee product quality, be easy to damage button, cause product rejection.
The utility model content
The purpose of this utility model is to provide a kind of button mold insert structure, the bad problem that burr causes occurs because of mold insert structure when having solved product shaping.
For achieving the above object, the technical scheme taked of the utility model is:
Design a kind of button core rod, comprise core body and be installed on inserting on the core body, the profile of inserting is consistent with button cavity shape to be formed, and the bottom margin of inserting is provided with outside protrusion makes the interior accent edge of button after the moulding be the expansion limit of chamfering or fillet.
As improvement of the technical scheme, continuous projection or the discontinuity projection of described expansion limit for stretching along the bottom margin of inserting.
The utility model beneficial effect is:
The utility model structural design novelty, more smooth and easy when making button installation and use by the burr that accent edge in the button after the moulding has been eliminated on the expansion limit being set in the bottom of inserting, increase the button feel.Simultaneously also need not manual intervention, reduced operating personnel, improved the qualification rate of product, further reduced production cost.

Accompanying drawing 10 is a D portion structure for amplifying schematic diagram in the accompanying drawing 9.
The specific embodiment
For ease of it will be appreciated by those skilled in the art that the utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 6, a kind of button mold insert structure comprises core body 1 and is installed on and insert 2 on the core body 1 that 2 profiles of inserting are consistent with button cavity shape to be formed.
Shown in accompanying drawing 7,8, for the assembling that makes the moulding button more smooth and easy and use more comfortable, under the prerequisite that does not influence the button serviceability, be provided with the expansion limit 21 of outside protrusion at 2 bottom margins of inserting, the accent edge is the structure of chamfering or fillet in the button after the production moulding, eliminate the problem that occurs burr in the prior art, improved the qualification rate of product greatly.And the button that forms out also can directly deliver to assembling place assembling, need not in addition that the arrangement personnel handle burr and defective products, greatly reduces production cost.
Expansion limit 21 in the present embodiment is the continuous projectioies that stretch along 2 bottom margins of inserting, and promptly expands limit 21 and is positioned at insert 2 bottoms and die joint 11 intersections.Expansion limit 21 is made up of vertical section 12 that is positioned at that bottom and die joint 11 directly contact and superposed tilting section 13, and the interior accent edge of the button after the moulding becomes chamfering structure thus.
In addition, expanding limit 21 can also be protruding along the intermittence that 2 bottom margins of inserting stretch, and the button of injection moulding formation is shown in accompanying drawing 8~10 thus.Can find out that from figure the interior accent edge of button 3 has formed an outside open breach 31,, button also can not occur and install and use the problem that has some setbacks even burr has appearred in the interior accent of the button of this version edge when injection moulding.
The foregoing description only is a preferred implementation of the present utility model, in addition, the utility model can also have other implementations, can be the circular arc transition as the expansion limit, make that the accent edge is a fillet in the button after the moulding, this structure can reach the utility model designing requirement equally.Need to prove that under the prerequisite that does not break away from the utility model design, any conspicuous replacement all should fall within the protection domain of the present utility model.
