Mold for eliminating surface unevenness of wax mold during profiling

Abstract

The utility model discloses a mold for eliminating surface unevenness of a wax mold during profiling. The mold comprises interval gaps which are distributed in a vertical extending mode and are perpendicular to a pressing plate. Comprising a left mold and a right mold which are in a vertical state, and an interval gap playing a role in exhausting is formed between the left mold and the right mold; a groove is formed between the opposite surfaces of the left mold and the right mold and forms a space for accommodating a wax mold after mold closing; and pressing plates for applying pressure downwards are mounted at the tops of the left mold and the right mold. The left mold and the right mold are pressed on the supporting table top to form an interval gap which is perpendicular to the pressing plate, when wax liquid is injected through the wax injection channel to fill the space for containing the wax mold, pressure can be relieved through the interval gap, and the situation that the upper mold and the lower mold are jacked open by the pressure due to the fact that the interval gap is completely sealed and not presented is avoided. The problem that the surface of the wax mold is uneven after the wax mold is formed between the upper mold and the lower mold is solved.

Description

Technical Field

[0001] The utility model relates to a mold for eliminating the uneven surface of a wax mold during molding, and belongs to the technical field of casting wax molds. Background Art

[0002] When casting, the shape of the casting component must be determined by wax model first, and then the shell is sandblasted and the molten metal is poured for molten casting. When using the wax mold to press the wax model, the upper mold 1 and the lower mold 2 need to leave a gap 3 for exhaust, such as Figure 1 As shown, see also Chinese Patent Publication No. CN211564418U.

[0003] Although the spacing gap 3 is at the mold joint of the upper mold 1 and the lower mold 2, and the wax injection nozzle can play a role in venting when injecting wax through the wax injection channel 6, when the upper mold 1 is pressed toward the lower mold 2 by the pressing plate 4, since the pressing plate 4 and the spacing gap 3 are both in the horizontal plane, the spacing gap 3 is often not presented and is completely sealed. The pressure during wax injection will cause the upper mold 1 and the lower mold 2 to be pushed apart, resulting in an uneven surface of the wax mold 5 after being pressed between the upper mold 1 and the lower mold 2. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a mold which can eliminate the uneven surface of the wax mold during molding.

[0005] The utility model is realized through the following technical solutions.

[0006] The utility model provides a mold for eliminating the uneven surface of a wax mold during molding, comprising:

[0007] Spaced gaps are distributed along the vertical extension and are perpendicular to the pressure plate.

[0008] It includes: a left mold and a right mold in an upright state, and a gap between the left mold and the right mold for exhausting air;

[0009] There is a groove between the opposite surfaces of the left mold and the right mold to form a space for accommodating the wax mold after the molds are closed;

[0010] A pressing plate for applying downward pressure is installed on the top of the left mold and the right mold.

[0011] Positioning holes are arranged at the four corners of the contact surface between the left mold and the right mold to perform positioning through positioning protrusions during mold closing.

[0012] The bottoms of the left mold and the right mold are provided with supporting tables which play a supporting role.

[0013] A wax injection channel for injecting wax liquid is provided between the left mold and the right mold.

[0014] There are wax molds in the left mold and the right mold.

[0015] The beneficial effect of the utility model is that the interval gap formed by pressing the left mold and the right mold on the supporting table is perpendicular to the pressing plate, and when the wax liquid is injected through the wax injection channel to fill the space accommodating the wax mold, the pressure can be released through the interval gap, avoiding the situation where the interval gap is completely sealed and the pressure pushes the upper mold and the lower mold apart, thereby solving the problem of uneven surface of the wax mold after molding between the upper mold and the lower mold.

[0019] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0020] like Figure 2 shown.

[0021] The present invention discloses a mold for eliminating the uneven surface of a wax mold during molding, comprising:

[0022] When in use, the left mold 7 and the right mold 8 are placed upright, and there is a groove between the opposite surfaces of the left mold 7 and the right mold 8 to form a space for accommodating the wax mold 5 after the molds are closed. At this time, there is a spacing gap 3 between the left mold 7 and the right mold 8 for exhaust, and the spacing gap 3 is distributed along the vertical extension; the four corners of the contact surface between the left mold 7 and the right mold 8 are provided with positioning holes to position them through positioning protrusions when the molds are closed.

[0023] A pressing plate 4 for applying downward pressure is installed on the top of the left mold 7 and the right mold 8, and a supporting table 9 is provided at the bottom of the left mold 7 and the right mold 8. The pressing plate 4 applies downward pressure to press the left mold 7 and the right mold 8 on the supporting table 9 so that the spacing gap 3 appears, and the spacing gap 3 is perpendicular to the pressing plate 4.

[0024] A wax injection channel 6 for injecting wax liquid is provided between the left mold 7 and the right mold 8. The wax liquid is injected into the space for accommodating the wax mold 5 after the left mold 7 and the right mold 8 are combined through the wax injection channel 6. The wax mold 5 is formed after the wax liquid solidifies.

[0025] The gap 3 formed by pressing the left mold 7 and the right mold 8 on the support table 9 is perpendicular to the pressing plate 4. When the wax liquid is injected through the wax injection channel 6 to fill the space containing the wax mold 5, the pressure can be released through the gap 3, avoiding the situation where the gap 3 is not completely sealed and the pressure pushes the upper mold 1 and the lower mold 2 apart, thereby solving the problem of uneven surface of the wax mold 5 after molding between the upper mold 1 and the lower mold 2. The left mold 7 and the right mold 8 are separated through the gap 3 later to take out the wax mold 5.
