Description

Technical Field

[0001] This utility model relates to the field of precision casting, specifically a gate bar that is easy to identify. Background Technology

[0002] The casting industry is developing rapidly, with a wide range of applications and increasingly fierce competition. No longer satisfied with ordinary carbon steel, stainless steel, and increasingly involving special materials, sometimes dozens or even hundreds of types, the identification of each process step in production presents certain difficulties. To facilitate production differentiation, the current method involves marking the process flow chart and the gating system with symbols such as one circle for stainless steel and four circles for 4A. However, this marking is easily confused or forgotten during each identification. Furthermore, directly marking the full material name at the gating system requires different wax molds, increasing production costs. Therefore, this application proposes a gating bar that facilitates easy identification. Utility Model Content

[0003] To address the existing problems, this utility model provides an easily identifiable gate bar, which can effectively solve the problems mentioned in the background art.

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] An easily identifiable sprue bar includes a sprue bar and a sprue cup integrally connected to the sprue bar. An identification block is welded to the side of the sprue cup, and the surface of the identification block is provided with a material mark.

[0006] As a further improvement of this utility model, the identification block is located at a position 20-30mm away from the top surface of the pouring cup.

[0007] As a further improvement of this utility model: the side of the pouring cup is provided with an insertion groove, and the identification block is inserted into the insertion groove and then welded.

[0008] As a further improvement of this utility model: the insertion groove is a stepped groove, and the side of the identification block is provided with an insertion head. The insertion head and the identification block form a stepped structure and match the stepped groove.

[0009] As a further improvement of this utility model, the material marking is recessed or protruded from the surface of the identification block.

[0010] As a further improvement of this utility model: the pouring cup is provided with an outer ring protrusion, and the planar dimension of the outer ring protrusion is larger than the planar dimension of the pouring cup.

[0011] As a further embodiment of this utility model: the pouring cup is conical, the outer ring is circular, and the outer diameter of the outer ring is 2-5mm larger than the outer diameter of the pouring rod at the relative position.

[0012] As a further improvement of this utility model, the distance between the outer ring convex ring and the top of the pouring cup is 10-15mm.

[0013] Compared with the prior art, the beneficial effects of this utility model are: by welding an identification block to the side of the pouring cup, the material markings on the identification block can be used to directly see the specific material, which is clear at a glance and easy to distinguish. Moreover, the identification block uses a separate mold, which can produce identification blocks of the same material in batches, resulting in low cost and easy production.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Combination Figures 1 to 3 This embodiment provides a conveniently identifiable sprue bar, comprising a sprue bar 1 and a sprue cup 2 integrally connected to the sprue bar 1. The sprue bar 1 and sprue cup 2 are prepared by pouring molten wax using a conventional mold. An identification block 3, also a wax model, is welded to the side of the sprue cup 2 using molten wax. The surface of the identification block 3 is provided with a material identifier 4, which indicates the material of the casting to be poured. This allows for a direct visual identification of the specific material of the casting after pouring. Identification blocks 3 with the same material identifier 4 are batch-produced using the same mold, saving costs and facilitating production.

[0020] Furthermore, the identification block 3 is positioned 20-30mm away from the top surface of the pouring cup 2 for easy and conspicuous identification.

[0021] Furthermore, the side of the pouring cup 2 is provided with an insertion groove 5. The identification block 3 is inserted into the insertion groove 5 and then welded, which improves the welding strength between the identification block 3 and the pouring cup 2 and prevents the identification block 3 from falling off the pouring cup 2. In order to further improve the welding strength, the insertion groove 5 is a stepped groove, and the side of the identification block 3 is provided with an insertion head 6. The insertion head 6 and the identification block 3 form a stepped structure and match the stepped groove.

[0022] Furthermore, the material identifier 4 can be recessed or protruded from the surface of the identification block 3, depending on the need. In this example, the material identifier is protruded from the surface of the identification block 3. After the casting is poured, the pouring cup 2 and the pouring rod 1 need to be cut off without affecting the appearance of the casting.

[0023] Furthermore, the pouring cup 2 is provided with an outer ring protrusion 7. The planar dimension of the outer ring protrusion 7 is larger than that of the pouring cup 2. Specifically, the pouring cup 2 is conical, and the outer ring protrusion 7 is circular. The outer diameter of the outer ring protrusion 7 is 2-5 mm larger than the outer diameter of the pouring rod 1 at the corresponding position. The distance between the outer ring protrusion 7 and the top of the pouring cup 2 is 10-15 mm. The outer ring protrusion 7 forms an annular groove in the mold shell of the pouring cup 2, which can prevent molten metal from splashing during pouring.

[0024] The working principle of this utility model is as follows: by welding the identification block 3 to the side of the pouring cup 2, the specific material can be directly seen by the material mark 4 on the identification block 3, which is clear at a glance and easy to distinguish. Moreover, the identification block 3 adopts a separate mold, and identification blocks 3 of the same material can be produced in batches, which is low in cost and easy to produce.
