Problems solved by technology

[0003] At present, there is no crushing device inside the existing wax melting device. Before use, the large block of wax must be broken into small pieces through the crushing device, and then the small wax block is put into the wax melting device, which is time-consuming and laborious. ;It is inconvenient to discharge the wax liquid after melting, and the work efficiency is low

Embodiment 1

[0040] A wax pattern casting device, comprising: a smelting chamber 1, including a feeding port 11; also comprising: a net knife 3, arranged in the smelting chamber 1, including several blade units 32, the blade units 32 are arranged obliquely, adjacent to each other A dividing gap is formed between the blade units 32; the briquetting assembly 2 is arranged in the melting chamber 1, a clamping space is provided between the briquetting assembly 2 and the net knife 3, and the feeding port 11 Connected to the clamping space, the surface of the pressing block assembly 2 facing the mesh knife 3 is a crushing pressing surface 21, and the pressing block assembly 2 and the mesh knife 3 have a first state in which the relative distance gradually decreases, And the second state where the relative distance between the two remains constant, the moving path of the pressing block assembly 2 and / or the net knife 3 is parallel to the blade unit 32 . Most of the raw materials currently used fo...

Embodiment 2

[0049] like image 3 As shown, the difference between this embodiment and Embodiment 1 is that the pressing block assembly 2 also includes:

[0050] The movable unit 22, the movable unit 22 has a first position accommodated in the pressing block assembly 2, and a second position protruding from the pressing block assembly 2 and extending into the grid unit. Utilizing the movable unit 22 embedded in the grid unit can push the paraffin fragments in the grid unit to fall off quickly.

[0051]Wherein, the movable unit 22 is provided with a first heating module 23 , and the movable unit 22 is electrically connected with the pressing block assembly 2 . After the movable unit 22 enters the grid unit, it can also heat the inner wall of the grid unit, so that the paraffin attached to the net knife 3 is melted and flows into the next processing unit.

[0052] In this embodiment, the surface of the pressing block assembly 2 opposite to the frame body 31 is provided with mutually matche...

Embodiment 3

[0055] A wax pattern casting method is characterized in that, comprising:

[0056] Heating tools used to break up paraffin;

[0057] The step of heating the paraffin tool is performed before crushing the paraffin raw material, or the step of heating the paraffin tool is performed simultaneously with the step of crushing the paraffin raw material.

[0058] Further, after the paraffin is crushed, an auxiliary tool is used to assist in heating the tool for crushing the paraffin. Specifically, a plurality of movable units 22 are embedded in the dividing gaps for dividing the paraffin wax plates, and the movable units 22 themselves generate heat for heating and cleaning.

[0059] Further, after the paraffin is crushed, an auxiliary tool is used to dredge the passage where the paraffin fragments fall. The dredging method includes embedding the passage to push the internal residual fragments to move, and / or using a heating tool to extend into the passage for heating.

[0060] The p...

Abstract

The invention relates to a wax mold casting device and method. The wax mold casting device comprises a smelting chamber which comprises a feeding port, a mesh cutter arranged in the smelting chamber and a pressing block assembly; the mesh cutter comprises a plurality of blade units, the blade units are obliquely arranged, and a division gap is formed between every two adjacent blade units; and the pressing block assembly is arranged in the smelting chamber, a clamping space is formed between the pressing block assembly and the mesh cutter, the feeding port communicates with the clamping space, the face, facing the mesh cutter, of the pressing block assembly is a crushing pressing face, the pressing block assembly and the mesh cutter have a first state that the relative distance is gradually decreased and a second state that the relative distance is kept unchanged, and a movement path of the pressing block assembly and / or the mesh cutter is parallel to the blade units. Due to the fact that the blade units are obliquely arranged, the blade units can be more easily cut into paraffin plates, the resistance borne by the paraffin plates is reduced, the number of the paraffin plates attached to the mesh cutter is smaller, and therefore loss of the paraffin plates in the crushing process is reduced.

Description

technical field [0001] The invention relates to the technical field of wax pattern casting, in particular to a wax pattern casting device and method. Background technique [0002] In the field of investment precision casting, paraffin wax is mainly used as the mold base, because the physical characteristics of paraffin wax are in a solid state at room temperature, and the mold base cannot be directly manufactured. In the prior art, the paraffin is usually melted into liquid and then injected into the molding mechanism, so a device for melting the paraffin should be provided in the production process. [0003] At present, there is no crushing device inside the existing wax melting device. Before use, the large block of wax must be broken into small pieces through the crushing device, and then the small wax block is put into the wax melting device, which is time-consuming and laborious. ; After the melting is completed, it is inconvenient to discharge the wax liquid, and the ...
