Abstract

A die for reflector comprises an external mold and an internal mold, wherein, the upper part of the external mold is of a reversed cone shape, the lower part of the external mold fits the shape of the tail of the reflector. The utility model is characterized in that the bottom of the external mold is provided with a hole corresponding to the tail hole of the reflector; a convex block and a spring are also provided, one end of the convex block passes through the hole on the bottom of the external mold, while the other end of the convex block is positioned with the external mold through the spring. The utility model can produce the glass reflector with a hole at the tail directly without making and cutting off the prolonged tail, thereby saving human and material resources greatly, and having strong creativity.

Description

The reflector mould

Technical field

The utility model relates to a kind of mould that is used to make glass light fixture reflector, and it is raw material that this mould is used for glass, make the reflector of light fixture of impact molding.

Background technology

Small-sized light fixture commonly used at present (as the light fixture that uses in the display sales counter), its reflector adopts glass to make with impact molding usually.Reflector comprises conical bowl portion and cylinder or rectangular columned afterbody, the afterbody central openings, existing such glass press tool, comprise external mold and internal mold, described internal mold is the staking punch that cooperates with the reflector inner surface configuration, and the inner chamber top of described external mold is bowl-shape, and the inner chamber bottom cooperates with the tail shape of reflector, because the restriction of manufacture craft, the bottom of external mold is slightly darker than reflector afterbody, during punching out, pours the glass of molten in external mold, suppress with internal mold, the demoulding after cooling off, at this moment, the reflector afterbody of acquisition is long and end sealing than the afterbody that needs, also need afterbody is amputated, could obtain required reflector.Owing to need saw to remove afterbody, cost of labor is higher, and causes certain waste in this process.Owing in punching course,, also have skim glass and enter even the bottom is concordant, cause the sealing in afterbody hole, therefore, industry personage all thinks, must adopt existing this class to deepen the mould of tail structure, and the redundance that amputates afterbody is made reflector.

Summary of the invention

The utility model purpose provides a kind of novel reflector mould, can directly strike out afterbody reflector with holes, thereby avoids because of sawing the man power and material's who causes except that unnecessary afterbody loss.

For achieving the above object, the technical solution adopted in the utility model is: a kind of reflector mould, comprise external mold and internal mold, the inner chamber top of described external mold is bowl-shape, the inner chamber bottom cooperates with the tail shape of reflector, and described external mold bottom is provided with and corresponding hole, reflector afterbody hole, also includes projection and spring, one end of projection passes the hole of external mold bottom, and the other end is by spring and external mold location.

In the technique scheme, be provided with the active projection in the bottom of external mold, this projection passes the hole of external mold bottom, a little more than the baseplane of external mold, during punching press, under the pressure of drift (internal mold), projection is depressed into concordant with the external mold bottom surface, at this moment, on the bottom surface, can generate the glass of skim, and work as the moment that drift leaves, projection rebounds under the effect of bottom spring, because the thickness of this layer glass is very little, the bounce-back of projection will make the fragmentation of this layer glass, form required hole.In actually operating technology,, the reflector afterbody after the demoulding can be toasted for guaranteeing the smooth of reflector afterbody.

In the technique scheme, the move distance for the control projection can be provided with step on described projection, and step top cooperates with the hole size of external mold bottom, and the shoulder of step is greater than the hole of external mold bottom, and the height of step is greater than the degree of depth in hole; Its difference of altitude makes and gets final product than high 10 to 1 millimeter of the bottom of external mold when projection is the highest.

In the technique scheme, corresponding to different reflector afterbodys, the hole of external mold bottom and the shape of projection are different, shape commonly used is two kinds, a kind of is that described external mold bottom is provided with a slot, projection one end is corresponding rectangle, and rectangle described here also can be the rectangular shape that is similar to that circle is omited at two; Another kind is that described external mold bottom is provided with two circular holes, and projection one end correspondence is provided with two cylindrical protrusions.

Because the technique scheme utilization, the utility model compared with prior art has following advantage:

1, because the utility model is provided with spring and projection cube structure in the bottom of external mold, can in pressing process, directly form afterbody with holes, the afterbody that does not need to make growth amputates again, thereby has saved lot of manpower and material resources.

2, the utility model has been abolished the custom thinking that must increase afterbody of thinking of passing through in the industry by the improvement to mould, and very strong creativeness is arranged.

Description of drawings

Accompanying drawing 1 is the structure cross-sectional schematic of the utility model embodiment one;

Accompanying drawing 2 is the local schematic top plan view of the inner cavity of external mold among the embodiment one.

Wherein: [1], external mold; [2], internal mold; [3], inner chamber; [4], projection; [5], spring; [6], step.

Embodiment

Below in conjunction with drawings and Examples the utility model is further described:

Embodiment one: shown in accompanying drawing 1, a kind of reflector mould, comprise external mold 1 and internal mold 2, inner chamber 3 tops of described external mold 1 are bowl-shape, inner chamber 3 bottoms cooperate with the tail shape of reflector, described external mold 1 bottom is provided with and corresponding hole, reflector afterbody hole, also include projection 4 and spring 5, projection 4 is provided with step 6, step 6 tops cooperate with the hole size of external mold 1 bottom, and the shoulder of step 6 is greater than the hole of external mold 1 bottom, and the height of step 6 is greater than the degree of depth in hole, step 6 one ends on the projection 4 pass the hole of external mold 1 bottom, and the other end is by spring 5 and external mold 1 location.

In the present embodiment, the height that the step 6 on the described projection 4 exposes external mold 1 bottom is 60.The shape in hole can be rectangle, Long Circle, also can be two circles that the shape of the step 6 on the projection 4 is then corresponding with the shape in hole.
