Description

Technical Field

[0001] This utility model relates to the field of bridge casting, and in particular to a bridge casting and pouring system. Background Technology

[0002] The axle body is a crucial component of a car, and its quality directly impacts vehicle safety. Currently, axle bodies are typically manufactured using casting. However, due to significant variations in wall thickness within the axle body structure, casting defects such as shrinkage cavities are prone to occur in the thicker areas during production.

[0003] Existing gating systems mainly employ a single-sided casting method, which leads to heat concentration in thick-walled areas during casting, potentially causing shrinkage cavities and affecting the overall quality of the product. To address this, this solution proposes a casting gating system for bridge bodies. Utility Model Content

[0004] The present invention proposes a bridge casting system that solves the problem that existing bridge casting systems are prone to causing shrinkage cavities in thicker parts of the casting during casting.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A casting and gating system for a bridge body includes a casting and a gating mechanism connected to one side of the casting;

[0007] The pouring mechanism includes a sprue and flow guiding components symmetrically connected to both sides of the sprue;

[0008] The flow guiding assembly includes a filter assembly connected to the sprue, a flow-limiting overlap one connected to the other end of the filter assembly, and a sprue connected to the other end of the flow-limiting overlap one. The other end of the sprue is connected to a horizontal sprue, the other end of the horizontal sprue is connected to a flow-limiting overlap two, the other end of the flow-limiting overlap two is connected to a conformal sprue connecting to the ingate, and one side of the sprue is connected to a riser connecting to the ingate.

[0009] The above technical solution not only allows for double-sided pouring, ensuring more uniform cooling and solidification of the casting, but also effectively prevents molten iron from concentrating in the thick-walled areas of the casting, thus dispersing heat and preventing the formation of shrinkage cavities.

[0010] As a further improvement to the above scheme, the gating system is an arc-shaped structure, and the riser connecting the ingate is located inside the gating system.

[0011] Through the above technical solution, the arc-shaped gating system helps to disperse heat and avoid heat concentration.

[0012] As a further improvement to the above solution, the filter assembly includes a housing and a filter screen installed inside the housing, with an inlet at one end of the housing and an outlet at the other end of the housing.

[0013] The above technical solution utilizes a filter screen to filter impurities in molten iron.

[0014] As a further improvement to the above scheme, a gate separation block is fixedly connected to the bottom of the outer periphery of the riser connecting the inner runner.

[0015] Through the above technical solution, the separation block is used to provide support during the separation of the product and the gating system.

[0016] As a further improvement to the above solution, chills are provided at both ends of the casting, and the chills are located at the thick-walled part of the casting.

[0017] The above technical solution allows for the cooling of areas with thicker casting walls.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. By setting two risers connected to the ingate, strong feeding is provided to two thick-walled sections. In addition, chills are set in the two thick-walled sections to accelerate the cooling rate of the thick-walled sections. At the same time, the arc-shaped sprue and the arc-shaped conformal sprue connected to the ingate can distribute the amount of molten iron in the riser section, alleviate the heat concentration in the riser section, and avoid shrinkage cavities caused by heat concentration.

[0020] 2. The filter components can filter impurities in the molten iron, thus preventing impurities from mixing into the casting and affecting its quality. In addition, the two pouring mechanisms can effectively distribute the amount of molten iron, allowing the casting to solidify simultaneously. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example 1:

[0029] Please combine Figure 1 - Figure 4 The bridge casting system of this embodiment includes a casting 1 and a casting mechanism 2 connected to one side of the casting 1. The two casting mechanisms can effectively distribute the amount of molten iron, thereby ensuring that the casting can solidify at the same time.

[0030] The pouring mechanism 2 includes a sprue 201 and flow guiding components symmetrically connected to both sides of the sprue 201;

[0031] The flow guiding assembly includes a filter assembly 202 connected to the sprue 201, a flow-limiting overlap 203 connected to the other end of the filter assembly 202, and a gating system 209 connected to the other end of the flow-limiting overlap 203. The other end of the gating system is connected to a runner 206, the other end of the runner 206 is connected to a flow-limiting overlap 207, and the other end of the flow-limiting overlap 207 is connected to a conformal gating system connected to an ingate 208. One side of the gating system 209 is connected to a riser connected to an ingate 204. The gating system 209 has an arc-shaped structure, and the riser connecting the ingate 204 is located inside the gating system 209. The arc-shaped gating system and the arc-shaped conformal gating system connecting the ingate can distribute the amount of molten iron at the riser connecting the ingate 204, thereby effectively relieving the heat at the riser connecting the ingate 204 and avoiding shrinkage cavities caused by heat concentration. The riser connecting the ingate 204 is located at the thickness of the casting wall. The riser connecting the ingate 204 is set to provide feeding, thereby avoiding shrinkage cavities during pouring.

[0032] The filter assembly 202 includes a housing and a filter screen installed inside the housing. The filter screen is a foam ceramic filter screen. One end of the housing has an inlet and the other end has an outlet. During casting, the molten iron is injected from the direct pouring channel 201, passes through the filter screen in the filter assembly 202, and then enters the distribution channel 209 through the flow-limiting overlap 203, thereby filtering and intercepting impurities in the molten iron.

[0033] A gate separation block 205 is fixed to the bottom of the outer periphery of the riser connecting the inner sprue 204. The separation block 205 is used to support the separation of the product and the gating system.

[0034] In this embodiment, the functions of flow rate limiting overlap 1 203 and flow rate limiting overlap 207 are both to control the flow rate of molten iron (liquid) and prevent it from flowing out too quickly, thereby ensuring that the surface of the casting is clean and free of defects.

[0035] The implementation principle of this embodiment is as follows: During casting, molten iron is injected from the sprue 201, and then the molten iron enters two casting mechanisms to spread the molten iron evenly. The molten iron entering the casting mechanism first passes through the filter assembly 202, so that impurities in the molten iron are intercepted by the filter screen. Then the molten iron enters the sprue 209 through the flow rate limiting overlap 203, then enters the horizontal sprue 206 through the sprue 209, then enters the conformal sprue connecting the inner sprue 208 through the flow rate limiting overlap 207, and finally enters the casting.

[0036] Example 2:

[0037] Combination Figure 1 , Figure 2 and Figure 4 The further improvement of this embodiment based on embodiment 1 is that: chills 3 are provided at both ends of the casting 1, and the chills 3 are located at the thick wall of the casting 1. The two chills 3 are respectively set at the thick wall positions at both ends of the casting, thereby accelerating the cooling speed of the molten iron and avoiding the formation of shrinkage cavities.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
