Splicing type pouring gate special for wax mould based on investment casting

Abstract

The utility model discloses a special splicing type pouring gate for a wax mold based on investment casting. The special splicing type pouring gate comprises a transverse pouring gate wax mold, and wax mold butt joint grooves are formed in the four corners of the transverse pouring gate wax mold; the positioning convex part wax molds are fixed at the top of the ingate butt-joint wax mold at intervals; and the ingate butt-joint wax mold is fixed with the wax mold butt-joint groove in a butt-joint manner. The hollow interior of the splicing wax mold is in butt joint with a positioning convex part wax mold on the ingate butt joint wax mold, so that the splicing wax mold can be positioned through the positioning convex part wax mold, and the shaking condition caused when a worker holds the positioning arc-shaped wax mold by hand to carry out fusion welding splicing is avoided; the problem that the fusion welding and splicing efficiency of an arc-shaped wax mold and a cross gate wax mold is low is solved.

Description

Technical Field

[0001] This utility model relates to a special splicing type gating system for wax patterns based on investment casting, belonging to the field of casting wax pattern technology. Background Technology

[0002] In investment casting, irregular wax models need to be connected by splicing (see Chinese Patent Publication No. CN207823929U for existing technology).

[0003] When assembling wax models, if the curved wax model is directly welded to the horizontal runner wax model, the curved wax model needs to be manually positioned to complete the welding. Since human hands can tremble, the welding process needs to be slow, which reduces the efficiency of welding the curved wax model to the horizontal runner wax model. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a special splicing type gating system for wax molds based on investment casting.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a special splicing type sprue for wax patterns based on investment casting, comprising:

[0007] The wax mold for the horizontal runner has wax mold docking grooves at all four corners.

[0008] It also includes an inner sprue docking wax mold and a positioning protrusion wax mold fixed at intervals on the top of the inner sprue docking wax mold, with the inner sprue docking wax mold docking groove docking and fixed.

[0009] It also includes an arc-shaped spliced ​​wax model; the spliced ​​wax model is hollow inside and is used to dock with the positioning protrusion wax model. The bottom surface of the spliced ​​wax model is welded to the horizontal runner wax model at the docking point of the inner runner docking wax model and the wax model docking groove.

[0010] The wax mold of the horizontal sprue has a light-reducing hole inside.

[0011] The lightening holes are distributed on the horizontal runner wax molds between each pair of the four wax mold docking grooves.

[0012] The top surface of the inner runner wax mold is flush with the top surface of the horizontal runner wax mold.

[0013] There are four inner sprue docking wax molds, which are distributed in the wax mold docking grooves at the four corners of the horizontal sprue wax mold. Each of the four inner sprue docking wax molds has multiple spaced positioning protrusions fixed on it.

[0014] The sizes of the four ingate joint wax molds are inconsistent, and the sizes of the positioning protrusion wax molds on the different ingate joint wax molds are also inconsistent.

[0015] The beneficial effects of this utility model are as follows: the hollow interior of the splicing wax mold is connected to the positioning protrusion on the inner sprue wax mold, so that the splicing wax mold can be positioned by the positioning protrusion wax mold, avoiding the shaking that occurs when using a manually positioned arc-shaped wax mold for welding and splicing, and solving the problem of low welding and splicing efficiency of arc-shaped wax mold and horizontal sprue wax mold.

[0018] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0019] like Figure 1 As shown.

[0020] This application discloses a special splicing type sprue for wax patterns based on investment casting, comprising:

[0021] The horizontal runner wax model 5 has a weight-reducing hole 2 inside. The four corners of the horizontal runner wax model 5 are provided with wax model docking grooves 1. The weight-reducing holes 2 are distributed on the horizontal runner wax model 5 between each pair of the four wax model docking grooves 1. The weight-reducing holes 2 reduce the weight of the horizontal runner wax model 5.

[0022] It also includes an inner runner docking wax mold 3 and a positioning protrusion wax mold 31 fixed at intervals on the top of the inner runner docking wax mold 3. After the inner runner docking wax mold 3 is docked with the wax mold docking groove 1, the top surface of the inner runner docking wax mold 3 is flush with the top surface of the horizontal runner wax mold 5.

[0023] There are four inner sprue docking wax molds 3, which are distributed in the wax mold docking grooves 1 at the four corners of the horizontal sprue wax mold 5. Each of the four inner sprue docking wax molds 3 has a number of spaced positioning protrusion wax molds 31 fixed on it. The four inner sprue docking wax molds 3 are not the same size, and the positioning protrusion wax molds 31 on the different inner sprue docking wax molds 3 are not the same size.

[0024] It also includes an arc-shaped spliced ​​wax model 4, which consists of four different sizes (only one is shown in the figure); the spliced ​​wax model 4 is hollow inside and is used to dock with the positioning protrusion wax model 31. The bottom surface of the spliced ​​wax model 4 is welded to the horizontal runner wax model 5 at the docking point of the inner runner docking wax model 3 and the wax model docking groove 1.

[0025] The hollow interior of the splicing wax mold 4 is aligned with the positioning protrusion 31 on the inner sprue wax mold 3, allowing the splicing wax mold 4 to be positioned by the positioning protrusion 31. This avoids the shaking that occurs when manually positioning the arc-shaped wax mold for welding and splicing, and solves the problem of low welding and splicing efficiency between the arc-shaped wax mold and the horizontal sprue wax mold.
