Description

Technical Field

[0001] This utility model relates to the field of building material preparation technology, specifically a silicon block mold that is easy to demold. Background Technology

[0002] Industrial silicon, also known as metallic silicon, is produced by drying and smelting silica sludge. Specifically, wet silica sludge is dried in a special oven and then transferred to a medium-frequency furnace for smelting and impurity removal. Silica sludge is a low-temperature antioxidant, typically soft, with a fine texture, light weight, high porosity, and strong water absorption. Dried silica exposed to air easily generates dust, while industrial silicon produced by medium-frequency furnace smelting is hard and brittle. Given the different characteristics of silicon materials at different stages of industrial silicon production, many problems remain to be solved in the drying, transfer, smelting, and crushing processes.

[0003] In the silicon smelting stage, molten silicon is injected into a mold and solidified to form a silicon block. Chinese patent "CN 221209816 U" discloses an ingot mold for industrial silicon casting. This patent solves the problem of burn risk caused by manual removal. However, the silicon block is prone to sticking to the bottom and side walls during the cooling and solidification process, which hinders the demolding of the silicon block. Utility Model Content

[0004] The purpose of this invention is to provide a silicon block mold that is easy to demold, so as to solve the problems mentioned above.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a silicon block mold that is easy to demold, comprising a mold body, an injection platform, and a side baffle plate. The mold body is a square open tray assembled sequentially from a head unit, a body unit, and a tail unit. An injection platform is provided at one end of the outer side of the tail unit. A side baffle plate is also provided between the tail unit and the injection platform. A first base is provided at the bottom of the mold body, and a second base is provided at the bottom of the injection platform.

[0006] Preferably, the head unit, body unit, and tail unit are all surrounded by multiple unit sides and unit bottoms, and there are no unit sides in the connection between the head unit and the body unit, or between the body unit and the tail unit.

[0007] Preferably, the two ends of the sides of the head unit, body unit, and tail unit are all connected by mortise and tenon joints, and fastening plates are provided between the head unit and the body unit, and between the body unit and the tail unit.

[0008] Preferably, the fastening plate has holes at both ends that are adapted to the shape and size of the protrusion, and the protrusion passes through the holes.

[0009] Preferably, the height of the injection platform is higher than the overall height of the mold body, and the inner side of the injection platform is provided with a certain tilt angle.

[0010] Preferably, the side baffle is secured with a steel cable, with one end of the steel cable fixed to one side of the tail unit and the other end fixed to one side of the injection platform.

[0011] Preferably, the width of the first base is shorter than the width of the mold body, and the width of the first base is longer than the total length of the body unit.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by setting up a quick-release head unit, body unit, and tail unit, the silicon block is prevented from sticking to the side wall during the cooling and forming process, thus avoiding obstruction of demolding. The head unit and tail unit are removed before demolding. During the demolding process, a forklift is used to lift the entire silicon block from the bottom of the mold, and it is naturally demolded under the influence of gravity. This avoids product defects or damage caused by improper demolding, and the product can be demolded smoothly. The process on the production line will be smoother, thereby improving the overall production efficiency.

[0014] 2. In this utility model, a side liquid baffle is provided between the injection platform and the mold body. When the high-temperature molten silicon liquid is poured from the injection platform, some of the silicon liquid will inevitably splash. At this time, the side liquid baffle can block the splashed high-temperature silicon liquid and ensure production safety. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-3 In this embodiment of the invention, an easy-to-demold silicon block mold includes a mold body 1, an injection platform 2, and a side baffle 3. The mold body 1 is a square open tray assembled sequentially from a head unit 11, a body unit 12, and a tail unit 13. The injection platform 2 is located at one outer end of the tail unit 13, and the side baffle 3 is also provided between the tail unit 13 and the injection platform 2. A first base 5 is provided at the bottom of the mold body 1, and a second base 6 is provided at the bottom of the injection platform 2. The side baffle 3 can block the high-temperature molten silicon splashed from the injection platform 2, ensuring production safety.

[0021] The head unit 11, the body unit 12, and the tail unit 13 are all surrounded by multiple unit sides and unit bottoms. The connection between the head unit 11 and the body unit 12, and between the body unit 12 and the tail unit 13, has no unit sides.

[0022] The head unit 11, the body unit 12, and the tail unit 13 are all connected by tenons and mortise at both ends on their sides. Fastening pieces 15 are provided between the head unit 11 and the body unit 12, and between the body unit 12 and the tail unit 13. The head unit 11, the body unit 12, and the tail unit 13 contain protrusions 14.

[0023] The fastening plate 15 has holes at both ends that are adapted to the shape and size of the protrusion 14, through which the protrusion 14 passes. The fastening plate 15 has a relatively simple structure, is easy to assemble and quick to disassemble, and has reliable connection performance, which can ensure the relative position stability between parts and prevent displacement or loosening during operation.

[0024] The height of the injection platform 2 is higher than the overall height of the mold body 1, and the inner side of the injection platform 2 is provided with a certain tilt angle. The tilt angle at the front end of the injection platform 2 can guide the molten silicon into the mold body, which can reduce the splashing caused when directly pouring molten silicon to a certain extent and avoid material waste.

[0025] The side baffle plate 3 is secured with a steel cable 4 on its outer side. One end of the steel cable 4 is fixed to one side of the tail unit 13, and the other end of the steel cable 4 is fixed to one side of the injection platform 2.

[0026] The width of the first base 5 is shorter than the width of the mold body 1, and the width of the first base 5 is longer than the total length of the body unit 12. The first base 5 raises the mold body 1 as a whole, and the portions of the mold body 1 on both sides that are longer than the first base 5 form a certain space with the ground, which facilitates subsequent demolding.

[0027] The working principle of this utility model is as follows: molten high-temperature silicon liquid is poured from the injection platform 2 and flows into the mold body 1 along the inclination angle of the injection platform 2. After the silicon liquid cools and solidifies, the fastening plates 15 are removed in sequence, and then the head unit 11 and the tail unit 13 are removed. At this time, since the first base 5 raises the mold as a whole, there is a large space between the silicon block where the head unit 11 and the tail unit 13 were originally located and the ground. Then, a forklift is used to lift the suspended part of the silicon block from the bottom. Since the mold body 1 has a large self-weight, the mold and the silicon block naturally separate during the process of lifting the silicon block, and demolding is performed.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
