Description

Technical Field

[0001] This utility model relates to the field of silicon metal casting, and more specifically, to a rapid prototyping mold for silicon metal casting. Background Technology

[0002] In the current silicon metal casting mold technology system, the mainstream cooling methods have certain limitations. Most existing molds choose to directly create cooling channels inside the mold. Once this cooling path is determined, it is difficult to change and lacks flexibility. Adjusting the cooling strategy for different shaped silicon metal products is almost impossible. While some designs use embedded cooling pipes, which optimize cooling to some extent, the cooling pipes are often fixed to the mold body by welding or casting, making the cooling pipes impossible to disassemble. When the cooling pipes become blocked or damaged, the entire mold must be repaired or replaced, which is costly, time-consuming, and labor-intensive. Furthermore, fixed cooling paths cannot be adaptively adjusted to the complex heat distribution during silicon metal casting, making it difficult to improve cooling efficiency and meet the process requirements of rapid silicon metal prototyping.

[0003] How to invent a rapid prototyping mold for silicon metal casting to improve these problems has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a rapid prototyping mold for silicon metal casting, which aims to improve the problem that the cooling path of existing casting molds is mostly fixed and cannot be changed or adjusted according to different casting requirements, resulting in relatively low cooling effect and slow molding.

[0005] This invention is implemented as follows: A rapid prototyping mold for silicon metal casting includes two mold bodies. Each mold body has a mold cavity on one side of its opposite side. A mold core is detachably installed in each mold cavity. A casting port communicating with the corresponding mold cavity is provided on the other side of one of the mold bodies. An installation groove is provided inside each of the two mold cavities. A detachable cooling mechanism is slidably connected in each installation groove. Each detachable cooling mechanism includes a sliding plate. A cooling pipe is embedded on the side of the sliding plate facing the corresponding mold cavity. The two ends of the cooling pipe are a water inlet and a water outlet, respectively. The water inlet and the water outlet extend from both sides of one end of the sliding plate to the outside of the sliding plate and are connected to an external water circulation cooling device.

[0006] In a preferred embodiment of this utility model, four rectangularly distributed positioning rods are fixedly installed on one of the mold bodies, and four positioning holes corresponding to the positioning rods are opened through one side surface of the other mold body, with each positioning rod slidably connected in the corresponding positioning hole.

[0007] In a preferred embodiment of this utility model, the opening of each mounting groove is provided on one end surface of the corresponding mold body, and a limiting mechanism for limiting the detachable cooling mechanism is provided at the opening of the mounting groove.

[0008] In a preferred embodiment of this utility model, the limiting mechanism includes a first connecting member and a second connecting part. The first connecting member is integrally disposed on one end surface of the mold body, and the second connecting part is integrally disposed on one end surface of the sliding disk. Threaded holes are provided on one side surface of both the first connecting member and the second connecting part, and the same limiting screw is threaded into the two threaded holes.

[0009] In a preferred embodiment of this utility model, the sliding disk has integrally formed extensions on both sides that are obliquely arranged to the sides of the corresponding mold cavity. The cross-sectional shape and size of the mounting groove are consistent with the cross-sectional shape and size of the sliding disk. Each cooling pipe extends on one side surface of the sliding disk to form a multi-dimensional cooling path.

[0010] In a preferred embodiment of this utility model, the multi-dimensional cooling path includes a main cooling path and a connecting path. The main cooling path is located between two extensions and covers one side surface of the sliding disk with the corresponding mold cavity as the center. The two connecting paths are the water inlet end and the water outlet end, which are connected to the main cooling path and are respectively arranged on the surface of the corresponding extension.

[0011] In a preferred embodiment of this utility model, the main cooling path is configured to correspond to the mold core and is simultaneously connected to the connecting paths on both sides.

[0012] In a preferred embodiment of this utility model, a filtration mechanism is provided at the water inlet end of the sliding disc. The filtration mechanism includes a sleeve, one end of which is detachably connected to the water inlet end. A filter screen is provided between the inner walls of the sleeve, and a connecting flange is provided at the other end of the sleeve.

[0013] The beneficial effects of this utility model are as follows: The rapid prototyping mold for silicon metal casting obtained by the above design improves the adaptability of the mold by setting a detachable mold core in the mold cavity on the opposite side of the two mold bodies. At the same time, in terms of cooling, a detachable cooling mechanism is adopted, and the sliding plate with corresponding cooling pipes can be replaced according to the mold core of different shapes and the corresponding heat distribution, so as to achieve efficient cooling and improve the molding speed of silicon metal casting.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments 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 scope of protection of this utility model.

[0021] Please see Figures 1 to 4This utility model provides a technical solution: a rapid prototyping mold for metal silicon casting, comprising two mold bodies 1, each mold body 1 having a mold cavity 101 on one opposite side surface, each mold cavity 101 having a mold core 102 detachably installed therein, and one of the mold bodies 1 having a casting port 103 communicating with the corresponding mold cavity 101 on the other side surface, each of the two mold cavities 101 having an installation groove 104 inside, and each installation groove 104 having a detachable cooling mechanism 2 slidably connected therein, each detachable cooling mechanism 2 including a sliding plate 201, the sliding plate 201 having a cooling pipe 202 embedded on the side surface facing the corresponding mold cavity 101, the two ends of the cooling pipe 202 being a water inlet and a water outlet respectively, the water inlet and the water outlet extending from both sides of one end surface of the sliding plate 201 to the outside of the sliding plate 201 and communicating with an external water circulation cooling device.

[0022] It should be noted that a connecting structure is provided between the interior of one of the mold cores 102 and the mold cavity 101. The connecting structure is also connected to the casting port 103. During casting, the liquid silicon enters the internal space formed by the two opposing mold cores 102 through the casting port 103 and the connecting structure. The connecting structure is a relatively mature existing technology, and its specific structure will not be described in detail here.

[0023] Please see Figure 2 One of the molds 1 has four rectangularly distributed positioning rods 105 fixedly installed on it, and the other mold 1 has four positioning holes 106 that correspond one-to-one with the positioning rods 105 through one side surface. Each positioning rod 105 is slidably connected in the corresponding positioning hole 106.

[0024] During mold closing, the positioning rod 105 is inserted into the positioning hole 106, serving as a guide and positioning element. This reduces deviations during mold closing, avoids problems such as flash and dimensional deviations caused by misalignment of the mold body 1, and improves product molding quality and yield.

[0025] Please see Figures 2 to 4 Each mounting slot 104 has an opening on one end surface of the corresponding mold body 1, and a limiting mechanism for limiting the detachable cooling mechanism 2 is provided at the opening of the mounting slot 104.

[0026] The opening of the mounting slot 104 is located on one end surface of the mold body 1, facilitating the installation and removal of the detachable cooling mechanism 2. The limiting mechanism improves the stability of the detachable cooling mechanism 2, ensuring that the cooling pipe 202 maintains good contact with the mold cavity 101 at all times, guaranteeing consistent cooling performance. Simultaneously, it prevents the cooling mechanism 2 from shifting or detaching when the mold vibrates or is subjected to external forces, avoiding damage to the mold and the cast product, and extending the mold's service life.

[0027] Furthermore, the limiting mechanism includes a first connecting member 107 and a second connecting part 204. The first connecting member 107 is integrally disposed on one end surface of the mold body 1, and the second connecting part 204 is integrally disposed on one end surface of the sliding disk 201. Threaded holes are provided through one side surface of the first connecting member 107 and the second connecting part 204, and the same limiting screw 108 is threaded into the two threaded holes.

[0028] The first connecting part 107 is integrally formed on one end surface of the mold body 1, and the second connecting part 204 is integrally formed on one end surface of the sliding disk 201. Both can be integrally formed with the mold body 1 and the sliding disk 201 through processes such as casting or forging. The threaded connection limiting mechanism has a simple structure, is easy to operate, and is convenient for disassembly and installation, which is beneficial for the maintenance and replacement of the cooling mechanism 2. It also has high connection strength and reliability, effectively preventing displacement of the cooling mechanism 2 during mold use and ensuring the normal operation of the cooling system.

[0029] Furthermore, the sliding disk 201 has integrally formed extensions 203 that are obliquely arranged on both sides of the corresponding mold cavity 101. The cross-sectional shape and size of the mounting groove 104 are consistent with the cross-sectional shape and size of the sliding disk 201. Each cooling pipe 202 extends on one side of the sliding disk 201 to form a multi-dimensional cooling path.

[0030] The extensions 203 are integrally formed on both sides of the sliding disk 201, obliquely arranged towards the corresponding mold cavities 101. Their shape and angle are correspondingly set according to the structure of the mold cavities 101 to achieve better enclosure of the mold cavities 101. The cross-sectional shape and size of the mounting groove 104 are consistent with the sliding disk 201, ensuring that the sliding disk 201 can be smoothly installed in the mounting groove 104. The setting of the extensions 203 allows the cooling pipes 202 to be closer to the edges and corners of the mold cavities 101, increasing the cooling area, improving the uniformity and efficiency of cooling, reducing the cooling time of the metal silicon products, and improving production efficiency. The multi-dimensional cooling path design can be optimized according to the shape and heat distribution of the mold cavities 101, further improving the cooling effect and ensuring the quality and performance of the products.

[0031] Furthermore, the multi-dimensional cooling path includes a main cooling path and a connecting path. The main cooling path is located between the two extensions 203 and covers one side surface of the sliding disk 201 with the corresponding mold cavity 101 as the center. The two connecting paths are the water inlet end and the water outlet end, which are connected to the main cooling path and are respectively set on the surface of the corresponding extension 203.

[0032] The main cooling path is located between the two extensions 203, covering one side of the sliding disk 201 with the corresponding mold cavity 101 as the center. It can adopt various shapes such as spiral or Z-shaped, depending on the shape and heat distribution of the mold core 102. The two connecting paths are the inlet and outlet ends connecting to the main cooling path and are respectively located on the surface of the corresponding extensions 203. The main cooling path and connecting paths allow for more orderly flow of coolant, improving cooling efficiency and uniformity, reducing temperature differences within the mold cavity 101, thereby improving the quality and performance of the cast product. This facilitates adjustment and optimization of the cooling path according to different mold core 102 shapes and cooling requirements, enhancing the mold's adaptability and flexibility.

[0033] Furthermore, the structural shape of the main cooling path corresponds to that of the mold core 102 and is simultaneously connected to the connecting paths on both sides.

[0034] The extension direction of the main cooling path is set according to the structural shape of the mold core 102. For example, the heat distribution inside the mold cavity 101 is not uniform for mold cores 102 of different sizes. The main cooling path extends in a meandering manner according to the specific heat distribution generated by the corresponding mold core 102 and connects to the connecting paths on both sides to avoid the main cooling path having an extra extension part that does not conform to the actual heat distribution, thus reducing the cooling efficiency.

[0035] Furthermore, a filter mechanism is provided at the water inlet end of the sliding disc 201. The filter mechanism includes a sleeve 205, one end of which is detachably connected to the water inlet end. A filter screen 206 is provided between the inner walls of the sleeve 205, and a connecting flange 207 is provided at the other end of the sleeve 205.

[0036] One end of the sleeve 205 is detachably connected to the water inlet, using threaded or clamp connections for easy installation and removal of the filter mechanism. The other end of the sleeve 205 is equipped with a connecting flange 207, which connects to an external coolant supply pipeline to ensure a normal coolant supply. The filter mechanism effectively prevents impurities in the coolant from entering the cooling pipe 202, avoiding blockage and damage, and extending the service life of the cooling system. It also reduces the impact of impurities on cooling performance, further improving cooling efficiency.

[0037] Working Principle: A detachable cooling mechanism 2 is installed in the mounting groove 104 within the mold cavity 101. The sliding disc 201 of this cooling mechanism 2 has extensions 203 on both sides, and cooling pipes 202 embedded in its surface form a multi-dimensional cooling path, including a main cooling path corresponding to the shape of the mold core 102 and a connecting path in the extensions 203. This optimizes coolant flow according to the heat distribution in the mold cavity 101, improving cooling efficiency and uniformity. The positioning rod 105 cooperates with the positioning hole 106 to ensure mold closing accuracy and reduce product deviation. The limiting mechanism at the opening of the mounting groove 104 ensures the stability of the cooling mechanism 2 through the first connecting piece 107, the second connecting part 204, and the limiting screw 108. The filter mechanism at the water inlet of the sliding disc 201 prevents impurities from clogging the cooling pipes 202. This efficient, convenient, and detachable cooling mechanism 2 effectively controls the temperature of the mold cavity 101, accelerates the cooling speed of the silicon metal, and thus achieves rapid molding of the silicon metal casting.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
