Description

Technical Field

[0001] This utility model relates to the field of casting, specifically to a casting system that facilitates slag collection and breakage. Background Technology

[0002] Automated casting production lines offer high efficiency and stable quality, but they are limited by the size of the sand box and have certain requirements for mold weight and individual casting weight. In order to obtain intact castings, a channel is often needed to allow the molten metal to fill the cavity smoothly and quickly within a certain time. This channel also needs to filter slag. In the casting industry, we call this channel the gating system.

[0003] Current casting systems include straight pouring channels and multiple horizontal pouring channels. One end of the horizontal pouring channel is connected to the straight pouring channel, and the other end is connected to the casting cavity. To prevent impurities from entering the casting cavity, filter blocks and slag collection bags are designed on the horizontal pouring channel. However, the problem with traditional casting systems is that it is not easy to disconnect the horizontal pouring channel later, and the subsequent processing of the casting system is quite difficult.

[0004] See the prior patent, patent number: ZL202011537582.9, patent name: Tide Sand Casting System. In this casting system, the filter block is located between the upper slag collection bag and the lower slow flow zone. The entire filter block is sandwiched in the middle. After the casting is completed, the horizontal runner needs to be broken. In the past, the metal part of the horizontal runner could only be cut by hydraulic shears. This operation is very damaging to workers and hydraulic shears, often exceeding the working intensity of the hydraulic shears and shortening their service life. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a casting system that is easy to collect slag and break, thus solving the technical problem that it is inconvenient to disconnect the casting system at the horizontal runner position in the past.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A casting system that facilitates slag collection and breakage is provided, including a straight pouring channel and at least one horizontal pouring channel, wherein the horizontal pouring channel is connected to the lower end of the straight pouring channel; the horizontal pouring channel includes a front-end horizontal pouring channel and a rear-end horizontal pouring channel, wherein the front-end horizontal pouring channel is connected to the straight pouring channel, and the rear-end horizontal pouring channel is connected to the casting cavity; a filter block, wherein the front-end horizontal pouring channel and the rear-end horizontal pouring channel are respectively connected to the left and right sides of the filter block; a rear slag collection bag is provided at the upper end of the rear-end horizontal pouring channel near the filter block, and a front slag collection bag is provided at the upper end of the front-end horizontal pouring channel near the filter block, wherein a clamping joint is formed between the rear slag collection bag, the upper surface of the filter block, and the front slag collection bag.

[0007] Furthermore, the filter block is a foam ceramic filter.

[0008] Furthermore, the filter block has a cuboid structure.

[0009] Furthermore, the lower end of the rear horizontal sprue near the filter block and the lower end of the front horizontal sprue near the filter block both form flared structures.

[0010] Furthermore, the lower end of the direct sprue is provided with a sprue socket, and the front end of the filter sprue is connected above the sprue socket.

[0011] The beneficial effects of this utility model are as follows: The casting system of this utility model combines slag filtering and breaking functions, reducing the amount of molten slag entering the casting cavity, significantly improving the quality of castings, and making it easier to obtain intact castings. Secondly, it is more user-friendly for the post-processing of the casting system. The horizontal runner is broken at the clamping point formed at the position of the filter block, which is the weakest area on the horizontal runner. This ensures that it can be clamped within the working strength range of the hydraulic clamp, extending the service life of the equipment. Attached Figure Description

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] This application provides a casting system that facilitates slag collection and breakage, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0016] To address the technical problem of inconvenient disconnection at the runner location in existing casting systems, one embodiment of this application provides a casting system that facilitates slag collection and breakage. This is described in detail below.

[0017] like Figure 1As shown, a casting system for easy slag collection and breakage includes a straight pouring channel 1 and at least one horizontal pouring channel, the horizontal pouring channel being connected to the lower end of the straight pouring channel 1; the horizontal pouring channel includes a front-end horizontal pouring channel 2 and a rear-end horizontal pouring channel 3, the front-end horizontal pouring channel 2 being connected to the straight pouring channel 1, and the rear-end horizontal pouring channel 3 being connected to the casting cavity; a filter block 4, the front-end horizontal pouring channel 2 and the rear-end horizontal pouring channel 3 being connected to the left and right sides of the filter block 4 respectively; the upper end of the rear-end horizontal pouring channel 3 near the filter block 4 is provided with a rear slag collection bag 31, the upper end of the front-end horizontal pouring channel 2 near the filter block 4 is provided with a front slag collection bag 21, and a clamping joint is formed between the rear slag collection bag 31, the upper surface of the filter block 4, and the front slag collection bag 21.

[0018] Specifically, as an optional implementation in this embodiment, the filter block 4 is a foam ceramic filter. Foam ceramic filters are existing, mature products that can be purchased directly from the market.

[0019] The filter block 4 can be cylindrical or cuboid. In this embodiment, the filter block 4 is preferably cuboid in shape.

[0020] Specifically, as an optional implementation method in this embodiment, such as Figure 1 As shown, the lower end of the rear horizontal gating channel 3 near the filter block 4 and the lower end of the front horizontal gating channel 2 near the filter block 4 both form flared structures.

[0021] The flared structure can make the most of the filter block 4, which is beneficial for the molten metal to be fully filtered in the filter block 4.

[0022] Specifically, as an optional implementation method in this embodiment, such as Figure 1 As shown, the lower end of the direct sprue 1 is provided with a sprue socket 11, and the front end of the filter sprue 2 is connected above the sprue socket 11.

[0023] The casting system of this invention is suitable for assembly line production, and has two horizontal casting channels.

[0024] The casting system of this invention is formed inside the sand mold. The molten metal enters from the sprue 1, then flows slowly through the bottom gate socket 11 before entering the runner. When the molten metal enters the rear runner 3 from the front runner 2, it is filtered by the filter block 4. The slag at the inlet of the filter block 4 floats into the front slag collection bag 21, and the slag at the outlet of the filter block 4 floats into the rear slag collection bag 31. The slag is effectively removed through the two collection bags. Finally, the molten metal flowing out from the rear runner 3 enters the casting cavity for casting. After the mold has solidified, the casting system is removed. At this time, the filter block 4 is cut off by hydraulic clamps. The filter block 4 is the weakest point in the runner, where the metal content is the lowest, making it easier to break.
