Detailed Implementation

[0033] 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.

[0034] like Figure 1 and Figure 2 As shown, an optical fiber splitter box mold includes a front mold core 200, a rear mold core 300, and a cooling structure 400.

[0035] The front mold core 200 is used to form the outer wall of the part to be injection molded 500. The top of the front mold core 200 is provided with a flow channel 150. The rear mold core 300 is used to form the inner wall of the part to be injection molded 500. A mold cavity for forming the part to be injection molded 500 is provided between the front mold core 200 and the rear mold core 300.

[0036] The rear model core 300 has a cooling cavity 310 inside. The outer wall shape of the cooling structure 400 is the same as the inner wall shape of the cooling cavity 310. The cooling structure 400 is set inside the cooling cavity 310.

[0037] The cooling structure 400 has a coolant circulation channel 410, which is located close to the outer surface of the cooling structure 400.

[0038] In this embodiment, by embedding a cooling structure 400 with the same inner wall structure as the cooling cavity 310 in the cooling cavity 310 of the rear mold core 300, the cooling structure 400 is fitted to the rear mold core 300, and a coolant circulation channel 410 is provided on the outer surface of the cooling structure 400, efficient and uniform cooling of the inner wall of the injection molded part 500 is achieved, which can significantly improve cooling efficiency, help shorten the injection molding cycle, and reduce deformation and internal stress caused by uneven temperature, thereby improving product quality and production efficiency.

[0039] In one possible implementation, the coolant circulation channel 410 is at the same distance from the surface of the cooling structure 400, and the surface thickness of the rear model core 300 is the same.

[0040] In this embodiment, the distance between the coolant circulation channel 410 and the surface of the cooling structure 400 is set to be the same, and the surface thickness of the rear mold core 300 is ensured to be uniform, achieving a more uniform and efficient cooling effect. This ensures that the coolant maintains the same heat exchange efficiency as it flows through various areas, thereby avoiding local overheating or insufficient cooling, and contributing to improved product quality and production stability. Simultaneously, the uniformity of the surface thickness of the rear mold core 300 further ensures uniform material flow and shrinkage during molding, reducing defects and deformation caused by material inhomogeneity.

[0041] like Figure 2 , Figure 3 and Figure 4 As shown, in one possible implementation, the coolant circulation channel 410 may include an inlet channel 411 and an outlet channel 412.

[0042] The water inlet channel 411 can be located at the center of the cooling structure 400, and the water inlet channel 411 is distributed from the bottom of the cooling structure 400 to the top of the cooling structure 400.

[0043] The water outlet channel 412 can be distributed on the outer surface of the cooling structure 400. The water outlet channel 412 can be provided with one, two, three or more channels, and the water inlet channel 411 is connected to the water outlet channel 412.

[0044] In another possible embodiment, the water inlet channel 411 may be distributed on the outer surface of the cooling structure 400. The water outlet channel 412 may be located at the center of the cooling structure 400, and the water outlet channel 412 is distributed from the bottom to the top of the cooling structure 400, and the top of the water inlet channel 411 is connected to the top of the water outlet channel 412.

[0045] In this embodiment, by placing the water inlet channel 411 at the center of the cooling structure 400 and distributing it from bottom to top, while the water outlet channel 412 is distributed on the outer surface and communicates with the water inlet channel 411, the uniform introduction and dispersed discharge of coolant are effectively achieved. This ensures that the coolant can flow quickly and evenly through all areas of the cooling structure 400, thereby improving the cooling efficiency of the mold, reducing heat accumulation during the injection molding process, facilitating the control of the temperature distribution of the injection molded parts, preventing deformation and internal stress, and ultimately improving the quality and production efficiency of the injection molded parts.

[0046] In one possible implementation, the coolant circulation channel 410 further includes an inlet pipe 413 and an outlet pipe 414.

[0047] One end of the water inlet pipe 413 is connected to the water outlet of the cooling equipment, and the other end extends into the water inlet channel 411. By adjusting the cooling equipment, the coolant of the cooling equipment can be introduced into the water inlet channel 411, thereby allowing the water in the water inlet pipe to enter the water outlet pipe.

[0048] One end of the outlet pipe 414 is connected to the outlet channel 412, and the other end is connected to the inlet of the cooling equipment. Thus, the coolant passing through the outlet channel 412 can be introduced into the outlet pipe 414, and then the coolant can be discharged from the outlet channel 412, so that the coolant can flow back to the cooling equipment for cooling.

[0049] In this embodiment, by introducing an inlet pipe 413 and an outlet pipe 414, a complete circulation of coolant is achieved from the cooling equipment to the coolant circulation channel 410 and back to the cooling equipment. This ensures a continuous and stable supply of coolant to the coolant circulation channel 410, improves cooling efficiency, and facilitates monitoring and adjustment of the cooling process, thereby further optimizing the injection molding process and improving product quality and production efficiency.

[0050] In one possible implementation, the cooling structure 400 can be made of a metallic material, for example, the material of the cooling structure 400 can be aluminum or beryllium copper.

[0051] In one possible implementation, a base 100 is also provided at the bottom of the rear model core 300 and the cooling structure 400, the rear model core 300 and the base 100 forming a cooling cavity 310.

[0052] A first sealing ring 110 is provided between the rear model core 300 and the base 100. The first sealing ring 110 is used to seal the cooling cavity 310.

[0053] In one possible implementation, a rear molding plate 120 is also provided between the front mold core 200 and the base 100, and the rear molding plate 120 can be fixed to the base 100 by means of bolts.

[0054] The rear mold plate 120 is disposed on the periphery of the rear mold core 300, and the rear mold plate 120 is provided with a limiting edge 121 near the bottom of the rear mold core 300. The limiting edge 121 and the rear mold plate 120 can be fixed by an integral connection or by a detachable connection by bolts. By adjusting the rear mold plate 120, the rear mold plate 120 can press the rear mold core 300 through the limiting edge 121 to fix the rear mold core 300 on the base 100.

[0055] In this embodiment, a rear molding plate 120 is provided between the front mold core 200 and the base 100, and a limiting edge 121 is provided on the rear molding plate 120 near the bottom of the rear mold core 300 to press the rear mold core 300 tightly, which can significantly enhance the stability and positioning accuracy of the rear mold core 300. The limiting edge 121 can effectively prevent the rear mold core 300 from shifting during the molding process, ensuring the consistency and high quality of the injection molded part 500, while improving production efficiency and stability.

[0056] In one possible implementation, a front mold plate 140 is also provided on the rear mold plate 120, and the front mold plate 140 can be fixed to the rear mold plate 120 by means of bolt connection.

[0057] A molding cavity 141 is formed between the front molding plate 140 and the rear molding plate 120, and the shape and size of the molding cavity 141 match the front mold core 200.

[0058] By adjusting the front mold platen 140, the front mold platen 140 is pressed onto the front mold core 200, so that the front mold core 200 is located in the molding cavity 141, thereby completing the molding process of the front mold core 200.

[0059] In this embodiment, a customizable molding cavity 141 is constructed by setting a front molding plate 140 on the rear molding plate 120, allowing the mold to flexibly adapt to front mold cores 200 of different shapes and sizes. This design increases the versatility and reusability of the mold, and reduces the cost and time of designing molds individually for each type of front mold core 200.

[0060] Furthermore, since the shape and size of the molding cavity 141 are precisely matched with the front mold core 200, the material can be accurately filled to the predetermined position during the molding process, reducing dimensional deviations and shape distortions caused by mold mismatch, thereby improving molding accuracy.

[0061] In one possible implementation, a seal is provided between the rear mold core 300 and the limiting edge 121, the seal including a second sealing ring 130 for sealing the mold cavity.

[0062] In one possible implementation, the number of the second sealing rings 130 is set to two or more; in this embodiment, the number of the second sealing rings 130 is two.

[0063] In this embodiment, by providing two or more second sealing rings 130 between the rear mold core 300 and the limiting edge 121, the combined use of multiple sealing elements can enhance the sealing effect of the mold cavity and further improve safety.

[0064] In this embodiment, the materials of the first sealing ring 110 and the second sealing ring 130 can be set as silicone or fluorosilicone and other materials resistant to high and low temperatures.

[0065] The working principle of this utility model embodiment is as follows:

[0066] During the injection molding process, molten plastic is injected into the mold cavity through the runner 150, and coolant is introduced into the coolant circulation channel 410 in the cooling structure 400 through the water inlet pipe 413.

[0067] As the cooling process proceeds, the coolant circulates within the coolant circulation channel 410. After absorbing heat, the coolant, whose temperature rises, returns to the cooling equipment through the outlet pipe 414 for further cooling, thereby achieving the cooling treatment of the part to be injected 500 and completing the injection molding process.

[0068] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
