Description

Technical Field

[0001] The invention relates to a processing device. Background Art

[0002] Thermal radiation elements, also known as heating elements and heat transfer elements, are devices used in industrial heating furnaces to increase the total radiation.

[0003] like Figure 1 The heat radiation element 10 is provided with a reflection cavity 11. When processing, refer to Figure 2 , a core mold 22, an outer mold 21, a powdered raw material is placed in the space 20 between the two, compacted, and then demolded to obtain an embryo body. Summary of the invention

[0004] The technical problem to be solved by the present invention is: In practice, in order to pursue a larger cavity diameter ratio (the ratio of the cavity volume to the cavity opening diameter), a conical reflection cavity has been designed. Figure 3 The heat radiation element 10 is provided with a reflection cavity 11. In this heat radiation element, the outer mold is easy to demould, and the lower end of the core mold is relatively large and difficult to demould. At present, there is no good way.

[0005] The technical solution of the present invention is specifically as follows:

[0006] A core mold for processing a heat radiation element is of a split type and is garlic-shaped as a whole, with a columnar core mold in the middle. A plurality of garlic-shaped core molds are radially arranged around the columnar core mold. The outer side surface of the structure in which the plurality of garlic-shaped core molds are combined is consistent with the surface of a radiation cavity for processing a heat radiation element, and the inner side surface is a columnar surface. The upper part of the core mold is a supporting part, and the supporting part is provided with two hoops, which fix the plurality of garlic-shaped core molds together. One of the garlic-shaped core molds is divided into three parts, specifically: a line connecting a midpoint C of the outer contour of the lower surface of the garlic-shaped core mold and two end points A and B of the inner contour of the lower surface of the garlic-shaped core mold is cut vertically upward, the part outside the line is the first split of the garlic-shaped core mold, and the remaining part is the first split of the garlic-shaped core mold.

[0007] The columnar core mold is extended upward to form an extension portion.

[0008] A demoulding method for a core mold for processing a heat radiation element as described above:

[0009] The first step is to take out the cylindrical core mold;

[0010] The second step is to take out the first part of the garlic clove-shaped core mold through the space after the columnar core mold is moved out, and the action is first moved toward the center;

[0011] The third step is to take out the two first garlic clove-shaped core mold parts through the space after the columnar core mold and the first garlic clove-shaped core mold parts are moved out;

[0012] Finally, the remaining garlic-shaped core mold is moved out through the space after the columnar core mold and the garlic-shaped core mold are moved out, and thus, the demoulding of the entire core mold is completed.

[0013] Compared with the prior art, the technical effect of the present invention is that the core mold is designed to be split, which can be easily demoulded and meets the needs of people's work. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figure 4 A mold for processing a heat radiation element includes a core mold 30 and an outer mold 20. The core mold 30 is arranged inside the outer mold 20. Powdered raw materials are placed in the space 21 between the two, compacted, and then demolded to obtain an embryo body.

[0023] The demoulding of the outer mold 20 is the same as that in the prior art and will not be described in detail.

[0024] In order to facilitate demoulding of the core mold, the core mold 30 is uniquely designed.

[0025] See also Figure 5-8 The core mold 30 is split and garlic-shaped as a whole, with a columnar core mold 35 in the middle. A plurality of garlic-shaped core molds 32 are radially arranged around the columnar core mold 35. The outer side surface of the structure in which the plurality of garlic-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 surface is a columnar surface.

[0026] The upper part of the core mold 30 is a supporting part 31, and the supporting part 31 is for the convenience of supporting.

[0027] The holding portion 31 is provided with two hoops 33 , and the hoops 33 fix the plurality of garlic clove-shaped core molds 32 together.

[0028] One of the garlic clove-shaped core molds 32 is divided into three parts, specifically: a line connecting 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 and B of the inner contour of the lower surface of the garlic clove-shaped core mold 32 (that is, line segments AC and BC) is cut vertically upward, and the part outside the line is the second garlic clove-shaped core mold split 322, and the remaining part is the first garlic clove-shaped core mold split 321.

[0029] like Figure 6 In order to facilitate demoulding of the columnar core mold 35, the columnar core mold 35 is extended upward to form an extension portion.

[0030] Its working principle is:

[0031] When the core mold 30 is demoulded, the first step is to take out the columnar core mold 35, which is similar to the core mold of the current technology and is relatively easy.

[0032] The second step is to take out the first garlic clove-shaped core mold part 321 through the space left by the columnar core mold 35. This action is to first move toward the center, as shown by arrow r1, which is larger outside and smaller inside, and is relatively easy.

[0033] The third step is to take out the two garlic clove-shaped core mold second parts 322 respectively through the space after the columnar core mold 35 and the garlic clove-shaped core mold first part 321 are moved out, see arrow r2.

[0034] Finally, the remaining garlic clove-shaped core mold 32 is moved out through the space after the columnar core mold 35 and the garlic clove-shaped core mold 32 are moved out. In this way, as shown by arrow r3, the demoulding of the entire core mold 30 is completed.

[0035] For other contents, please refer to the prior art.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, which should also be regarded as the scope of protection of the present invention.
