Description

Core mold for processing heat radiation element and demolding method thereof

Technical Field

The invention relates to a processing device.

Background

The heat radiation element, which is also a heating element and a heat transfer element, is a device for increasing the total radiation quantity of the industrial heating kiln.

As shown in fig. 1, the heat radiating member 10 is provided with a reflective cavity 11. In the process, referring to fig. 2, a core mold 22 and an outer mold 21 are provided with powdery raw materials in a space 20 therebetween, and then are compacted and demolded to obtain a green body.

Disclosure of Invention

The technical problems to be solved by the invention are as follows: in practice, in order to pursue larger cavity diameter ratios (ratio of cavity volume to orifice diameter), conical reflective cavities have now been designed, see fig. 3, the heat radiating element 10 being provided with a reflective cavity 11. The external mold of the heat radiation element is easy to demould, the lower end of the core mold is larger, and the demoulding is difficult, and at present, no method exists.

The technical scheme of the invention is as follows:

the utility model provides a processing heat radiation component's mandrel, it is split type, wholly is the garlic form, the centre is the column mandrel, radial a plurality of garlic clove form mandrels that are equipped with around the column mandrel, the lateral surface of the structure that a plurality of garlic clove form mandrel are in the same place is unanimous with the surface in processing heat radiation component's radiation chamber, its inboard face is the column face, the upper portion of mandrel is for adding the portion of holding, it is equipped with two hoops to add the portion of holding, the hoop is in the same place a plurality of garlic clove form mandrels are fixed, one of them garlic clove form mandrel divide into the triplex, specifically do: and a connecting line of the midpoint C of the outer contour of the lower surface of the garlic clove-shaped core die and two end points A, B of the inner contour of the lower surface of the garlic clove-shaped core die is vertically cut upwards, the part outside the connecting line is a first garlic clove-shaped core die split body, and the rest part is the first garlic clove-shaped core die split body.

The columnar core mold is extended upwards to form an extension part.

A method of releasing a core mold for processing a heat radiation member as described above:

firstly, taking out the columnar core mold;

secondly, taking out the first split body of the garlic clove-shaped core mould through the space after the columnar core mould is moved out, wherein the action firstly moves towards the central part;

thirdly, the first garlic clove-shaped core mould components are respectively taken out through the space formed by the first garlic clove-shaped core mould components after the first garlic clove-shaped core mould components are moved out;

finally, the remaining garlic clove-shaped core mold is removed through the space after the cylindrical core mold and the garlic clove-shaped core mold are removed, so that the whole core mold is demoulded.

Compared with the prior art, the core mold has the technical effects that the core mold is designed to be split, so that the core mold can be conveniently demolded, and the working requirements of people are met.

Detailed Description

As shown in fig. 4, a mold for processing a heat radiation member includes a core mold 30 and an outer mold 20, the core mold 30 is provided inside the outer mold 20, a powdery raw material is placed in a space 21 therebetween, and a green body is obtained by tamping and then releasing.

The demolding of the outer mold 20 is the same as in the prior art and will not be described in detail.

The present mandrel 30 is uniquely designed to facilitate the demolding of the mandrel.

Referring to fig. 5-8, the core mold 30 is a split type, and is garlic-shaped as a whole, the middle is a columnar core mold 35, a plurality of garlic clove-shaped core molds 32 are radially arranged around the columnar core mold 35, the outer side of the structure in which the plurality of garlic clove-shaped core molds 32 are combined is consistent with the surface of the radiation cavity for processing the heat radiation element, and the inner side is a columnar surface.

The upper portion of the core mold 30 is a holding portion 31, and the holding portion 31 is for holding convenience.

The holding portion 31 is provided with two hoops 33, and the hoops 33 fix a plurality of garlic clove-shaped core molds 32 together.

One of the garlic clove-shaped core molds 32 is divided into three parts, specifically: the connecting line (i.e. line segments AC and BC) between the midpoint C of the outer contour of the lower surface of the garlic clove-shaped core mold 32 and the two end points A, B of the inner contour of the lower surface of the garlic clove-shaped core mold 32 is cut vertically upward, the outer side of the connecting line is the first garlic clove-shaped core mold split 322, and the rest is the first garlic clove-shaped core mold split 321.

As shown in fig. 6, in order to facilitate the mold release of columnar core mold 35, columnar core mold 35 is extended upward to form an extension.

The working principle is as follows:

when the core mold 30 is demolded, the columnar core mold 35 is taken out in the first step, which is relatively easy like the core mold of the prior art.

In the second step, the garlic clove-shaped core mold first divided body 321 is taken out through the space after the cylindrical core mold 35 is removed, and this operation is first moved toward the center portion, which is relatively easy to be large outside and small inside, see arrow r 1.

In the third step, the two garlic clove shaped mandrel first sub-bodies 322 are respectively taken out through the space after the cylindrical mandrel 35 and the garlic clove shaped mandrel first sub-body 321 are removed, see arrow r 2.

Finally, the remaining garlic clove-shaped core mold 32 is removed through the space after the cylindrical core mold 35 and the garlic clove-shaped core mold 32 are removed, so that the whole core mold 30 is completely demolded, see arrow r 3.

See the prior art for additional details.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various changes and modifications can be made without departing from the overall concept of the present invention, and these should also be considered as the protection scope of the present invention.
