Description

Technical Field

[0001] This utility model relates to the field of sprue removal technology, and in particular to a sprue removal mold. Background Technology

[0002] Most plastic products are made using injection molding. During the injection molding process, a gate needs to be opened on the mold. This gate is connected to the mold cavity and is used to inject molten injection material into the mold cavity. The plastic material enters the mold cavity to form the product. The corresponding gate on the product where the plastic material enters is called the sprue. In order to ensure the efficiency of injection molding, multiple cavities are usually set on the injection mold, and multiple gates are used. This results in multiple sprues being formed on the finished injection molded product.

[0003] In the existing technology, molds are usually used to cut off the sprue on the product. However, when the sprue is formed on the upper surface of the product, the sprue cut off by the cutter will fall onto the product. If the upper surface of the product has a groove or other structure, the cut-off sprue will easily fall into the groove, making it difficult to collect and thus affecting the production efficiency of the product. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides a sprue cutting mold, which avoids the problem that sprues fall into grooves and are difficult to collect when the product surface has grooves or other structures, thereby improving the production efficiency of the product.

[0005] The technical effect to be achieved by this utility model is realized through the following technical solution:

[0006] This utility model provides a sprue cutting mold, comprising:

[0007] Upper mold base assembly;

[0008] The cutting blade assembly is connected to the bottom surface of the upper mold base assembly and slides between a first position and a second position;

[0009] A lower mold base assembly, located below the cutter assembly and movably disposed relative to the upper mold base assembly, includes a lower template and a positioning seat. The positioning seat is disposed on the side of the lower template near the cutter assembly and has a placement area for placing products.

[0010] A receiving component is located at the first position;

[0011] When the upper mold base assembly and the lower mold base assembly are closed, the cutting blade assembly slides from the second position to the first position to cut off the sprue on the product and cause the sprue to fall into the receiving assembly.

[0012] In some implementations, the upper mold base assembly includes an upper template and a spring-loaded mechanism, the spring-loaded mechanism being elastically connected to the bottom surface of the upper template, and the cutter assembly being slidably connected to the bottom surface of the upper template.

[0013] In this implementation, when the upper mold plate is driven close to the lower mold base assembly, the spring-loaded mechanism abuts against the product to fix the product on the positioning seat, thereby avoiding the problem of the product shaking or shifting when the cutter assembly cuts off the sprue.

[0014] In some implementations, the spring-loaded mechanism includes a connecting column, a spring-loaded plate, and an elastic element. The first end of the connecting column is connected to the bottom surface of the upper template, the spring-loaded plate is connected to the second end of the connecting column, and the elastic element is sleeved on the connecting column with its opposite ends abutting against the upper template and the spring-loaded plate, respectively.

[0015] In this implementation, after the product is placed in the placement area of ​​the positioning seat, the spring plate flexibly abuts against the product under the action of the elastic element, thereby fixing the product in the placement area.

[0016] In some implementations, the spring plate has a clearance hole.

[0017] In some implementations, the cutter assembly includes a cutter fixing block and a sprue cutter, the sprue cutter being connected to the cutter fixing block, and the cutter fixing block being slidably connected to the upper template.

[0018] In some implementations, the sprue removal mold further includes a cutter drive unit, which is driven and connected to the cutter fixing block.

[0019] In this implementation, the cutter drive unit drives the cutter fixing block to slide, which in turn drives the sprue cutter to slide, so that the sprue cutter can slide repeatedly between the first position and the second position, thus ensuring the reliability of the cutter assembly.

[0020] In some implementations, the cutter assembly further includes a slide rail and a slider, the slide rail being connected to the upper template, and the slider being connected to the cutter fixing block and slidably connected to the slide rail.

[0021] In some implementations, the receiving assembly includes a receiving groove located downstream of the cutter assembly and connected to the upper mold base assembly.

[0022] In this implementation, when the cutter assembly slides from the second position to the first position, it cuts off the sprue on the product during the sliding process and causes the cut-off sprue to fall into the receiving groove. The receiving groove is connected to the upper mold base assembly, so that the receiving groove moves with the movement of the upper mold base assembly, thus eliminating the need for additional drive components and ensuring that the receiving groove does not mechanically interfere with other components.

[0023] In some implementations, the sprue removal mold further includes a guide rod assembly, which is movably disposed between the upper mold base assembly and the lower mold base assembly.

[0024] In this implementation, the upper mold base assembly is connected to the lower mold base assembly via a guide rod assembly, thereby ensuring that the upper mold base assembly can be aligned with the lower mold base assembly during mold closing, thus ensuring the reliability of the overall structure.

[0025] In some implementations, the guide rod assembly includes a first guide rod fixing sleeve, a second guide rod fixing sleeve, and a guide rod. The first guide rod fixing sleeve is connected to the upper mold base assembly, the second guide rod fixing sleeve is connected to the lower mold base assembly, and the first end of the guide rod passes through the first guide rod fixing sleeve and is connected to the upper mold base assembly, while the second end is movably passed through the second guide rod fixing sleeve.

[0026] In summary, this utility model has at least the following advantages:

[0027] The sprue cutting mold provided by this utility model has an upper mold base assembly and a lower mold base assembly that are movably arranged relative to each other. The cutting blade assembly is connected to the side of the upper mold base assembly near the lower mold base assembly and can slide between a first position and a second position. The receiving assembly is set at the first position, so that after the cutting blade assembly cuts off the sprue on the product, the sprue cut off by the cutting blade assembly can fall into the receiving assembly as the cutting blade assembly moves. This avoids the problem that the sprue is not easy to collect when it falls into the groove when there are grooves or other structures on the product surface, thereby improving the production efficiency of the product.

[0040] 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. The described embodiments are some, but not all, of the embodiments of this utility model.

[0041] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0042] Example 1:

[0043] Please see the appendix Figure 1 ~Appendix Figure 3 The sprue cutting mold of this utility model includes an upper mold base assembly 100, a cutter assembly 200, a lower mold base assembly 300, and a receiving assembly 400.

[0044] In this regard, please combine Figure 1 and Figure 2 , Figure 1 The diagram illustrates the structural relationship between the upper mold base assembly 100, the cutter assembly 200, the lower mold base assembly 300, and the receiving assembly 400 in this embodiment of the present invention. Figure 2The diagram illustrates the specific structure of the lower mold base assembly 300 in this embodiment of the present invention. Specifically, the cutter assembly 200 is connected to the bottom surface of the upper mold base assembly 100 and slides between a first position and a second position; the lower mold base assembly 300 is located below the cutter assembly 200 and is movably disposed relative to the upper mold base assembly 100. The lower mold base assembly 300 includes a lower template 310 and a positioning seat 320. The positioning seat 320 is disposed on the side of the lower template 310 near the cutter assembly 200 and has a placement area 321 for placing the product 700; the receiving assembly 400 is disposed at the first position. When the upper mold base assembly 100 and the lower mold base assembly 300 are closed, the cutter assembly 200 slides from the second position to the first position to cut off the sprue on the product 700 and cause the sprue to fall into the receiving assembly 400.

[0045] In this embodiment, the upper mold base assembly 100 and the lower mold base assembly 300 are movably arranged relative to each other, thereby realizing mold closing and mold opening. The cutter assembly 200 is connected to the bottom surface of the upper mold base assembly 100 and can slide repeatedly between a first position and a second position. The receiving assembly 400 is disposed at the first position, so that the sprue cut by the cutter assembly 200 can fall into the receiving assembly 400 as the cutter assembly 200 moves.

[0046] Specifically, when performing sprue removal on product 700, the upper mold base assembly 100 and the lower mold base assembly 300 are first driven to move away from each other to open the mold. Product 700 is placed in the placement area 321 on the positioning seat 320 by external equipment or manual operation to fix product 700 on the positioning seat 320. Then, the upper mold base assembly 100 and the lower mold base assembly 300 are driven to move closer to each other to close the mold. After the mold is closed, the cutter assembly 200 is driven to slide from the second position to the first position. During the process of the cutter assembly 200 sliding from the second position to the first position, the cutter assembly 200 removes the sprue from the upper surface of product 700. As the cutter assembly 200 moves, the removed sprue is carried into the receiving assembly 400, thereby realizing the automatic collection of the removed sprue.

[0047] In the aforementioned sprue cutting mold, the upper mold base assembly 100 and the lower mold base assembly 300 are movably arranged relative to each other. The cutter assembly 200 is connected to the side of the upper mold base assembly 100 near the lower mold base assembly 300 and can slide between a first position and a second position. The receiving assembly 400 is arranged at the first position, so that after the cutter assembly 200 cuts the sprue on the product 700, the sprue cut by the cutter assembly 200 can fall into the receiving assembly 400 as the cutter assembly 200 moves. This avoids the problem that the sprue is difficult to collect when it falls into the groove when there are grooves or other structures on the surface of the product 700, thereby improving the production efficiency of the product 700.

[0048] In some preferred embodiments, please refer to Figure 3 , Figure 3 The diagram illustrates the structural relationship between the upper template 110 and the spring-loaded mechanism 120 in this embodiment of the invention. Specifically, the upper mold base assembly 100 includes the upper template 110 and the spring-loaded mechanism 120. The spring-loaded mechanism 120 is elastically connected to the bottom surface of the upper template 110, and the cutter assembly 200 is slidably connected to the bottom surface of the upper template 110. When the upper template 110 is driven close to the lower mold base assembly 300, the spring-loaded mechanism 120 abuts against the product 700 to fix the product 700 on the positioning seat 320, thereby preventing the product 700 from shaking or shifting when the cutter assembly 200 cuts off the sprue.

[0049] In some preferred embodiments, please continue to refer to Figure 3 , Figure 3 The diagram illustrates the structural relationship between the connecting column 121, the spring-loaded plate 122, and the elastic element 123 in this embodiment of the present invention. Specifically, the spring-loaded mechanism 120 includes a connecting column 121, a spring-loaded plate 122, and an elastic element 123. The first end of the connecting column 121 is connected to the bottom surface of the upper template 110, the spring-loaded plate 122 is connected to the second end of the connecting column 121, and the elastic element 123 is sleeved on the connecting column 121 with its opposite ends abutting against the upper template 110 and the spring-loaded plate 122, respectively. After the product 700 is placed in the placement area 321 of the positioning seat 320, the spring-loaded plate 122 flexibly abuts against the product 700 under the force of the elastic element 123, thereby fixing the product 700 in the placement area 321. The connecting column 121 ensures the direction of the force of the elastic element 123, ensuring that the force of the elastic element 123 is correctly applied to the spring-loaded plate 122, avoiding the problem of damage to the product 700 when the elastic plate rigidly abuts against it. Preferably, the elastic element 123 can be a spring.

[0050] In some preferred embodiments, the spring-loaded plate 122 has a clearance hole 1221. The clearance hole 1221 is used to avoid partially obstructing the structure on the product 700, thereby allowing the spring-loaded plate 122 to fit more closely and tightly onto the product 700, increasing the contact area between the spring-loaded plate 122 and the product 700, and thus enhancing the stability of the product 700. Furthermore, the clearance hole 1221 also serves as a limiting function, enabling the spring-loaded plate 122 to position the product 700, further ensuring that the cutter assembly 200 can accurately cut off the sprue on the product 700.

[0051] Example 2:

[0052] The difference between this embodiment and Embodiment 1 is that this embodiment further optimizes the structure of the sprue cutting mold of this utility model. Please refer to the appendix. Figure 3 , Figure 3The diagram illustrates the structural relationship between the cutter fixing block 210 and the sprue cutter 220 in this embodiment of the present invention.

[0053] The cutter assembly 200 includes a cutter fixing block 210 and a sprue cutter 220. The sprue cutter 220 is connected to the cutter fixing block 210, and the cutter fixing block 210 is slidably connected to the upper template 110.

[0054] In this embodiment, when the cutter fixing block 210 slides, it drives the sprue cutter 220 to slide, allowing the sprue cutter 220 to slide repeatedly between the first and second positions, thereby achieving the removal of the sprue from the product 700. The sprue cutter 220 is slidably connected to the upper template 110 via the cutter fixing block 210, which facilitates the maintenance and replacement of the sprue cutter 220 and makes the overall structure more reliable.

[0055] In some preferred embodiments, the sprue removal mold further includes a cutter drive 500, which is driven and connected to the cutter fixing block 210. The cutter drive 500 drives the cutter fixing block 210 to slide, thereby driving the sprue cutter 220 to slide, so that the sprue cutter 220 can slide repeatedly between a first position and a second position, ensuring the reliability of the cutter assembly 200.

[0056] In some more preferred embodiments, the cutter assembly 200 further includes a slide rail 230 and a slider 240. The slide rail 230 is connected to the upper template 110, and the slider 240 is connected to the cutter fixing block 210 and slidably connected to the slide rail 230. The slider 240 is slidably connected to the slide rail 230 so that the cutter fixing block 210 can be smoothly slidably connected to the upper template 110, thereby improving the stability of the cutter fixing block 210 during sliding and further ensuring the stability of the sprue cutter 220, resulting in a smoother surface on the product 700 after the sprue is removed.

[0057] Example 3:

[0058] The difference between this embodiment and Embodiment 2 is that this embodiment further optimizes the structure of the sprue cutting mold of this utility model. Please refer to the appendix. Figure 4 , Figure 4 The diagram illustrates the structural relationship between the receiving groove 401 and the cutting blade assembly 200 in this embodiment of the present invention.

[0059] The receiving assembly 400 includes a receiving groove 401, which is located downstream of the cutter assembly 200 and connected to the upper mold base assembly 100.

[0060] In this embodiment, when the cutter assembly 200 slides from the second position to the first position, it cuts off the sprue on the product 700 during the sliding process, causing the cut-off sprue to fall into the receiving groove 401. The receiving groove 401 is connected to the upper mold base assembly 100, so that the receiving groove 401 moves with the movement of the upper mold base assembly 100, thereby eliminating the need for additional drive components and ensuring that the receiving groove 401 does not mechanically interfere with other components.

[0061] In some preferred embodiments, please continue to refer to Figure 4 , Figure 4 The diagram illustrates the structural relationship between the guide rod assembly 600, the upper mold base assembly 100, and the lower mold base assembly 300 in this embodiment of the invention. Specifically, the sprue removal mold further includes the guide rod assembly 600, which is movably disposed between the upper mold base assembly 100 and the lower mold base assembly 300. The upper mold base assembly 100 is connected to the lower mold base assembly 300 via the guide rod assembly 600, thereby ensuring that the upper mold base assembly 100 can be aligned with the lower mold base assembly 300 during mold closing, thus ensuring the reliability of the overall structure.

[0062] In some more preferred embodiments, the guide rod assembly 600 includes a first guide rod fixing sleeve 610, a second guide rod fixing sleeve 620, and a guide rod 630. The first guide rod fixing sleeve 610 is connected to the upper mold base assembly 100, and the second guide rod fixing sleeve 620 is connected to the lower mold base assembly 300. The first end of the guide rod 630 passes through the first guide rod fixing sleeve 610 and is connected to the upper mold base assembly 100, while the second end is movably inserted through the second guide rod fixing sleeve 620. When the mold is closed, the upper mold base assembly 100 and the lower mold base assembly 300 move closer to each other, and the second end of the guide rod 630 passes through the second guide rod fixing sleeve 620, thereby achieving mold closure. When the mold is opened, the upper mold base assembly 100 and the lower mold base assembly 300 move further apart, and the second end of the guide rod 630 exits from the second guide rod fixing sleeve 620, thereby achieving mold opening.

[0063] In this utility model, the sprue cutting mold has an upper mold base assembly 100 and a lower mold base assembly 300 that are movably arranged relative to each other. The cutter assembly 200 is connected to the side of the upper mold base assembly 100 near the lower mold base assembly 300 and can slide between a first position and a second position. The receiving assembly 400 is set at the first position, so that after the cutter assembly 200 cuts the sprue on the product 700, the sprue cut by the cutter assembly 200 can fall into the receiving assembly 400 as the cutter assembly 200 moves. This avoids the problem that the sprue is not easy to collect when it falls into the groove when there are grooves or other structures on the surface of the product 700, thereby improving the production efficiency of the product 700.
