Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a one-outlet and two-fine-water-inlet structure of a lower shell of a router. Background Art

[0002] A one-out-two mold is a mold designed so that when the mold is closed and the plastic melt is injected, the mold design can produce two products of different shapes based on the mold structure after the melt solidifies. Generally, a one-out-two mold is mostly composed of multiple molds. These molds can be opened with fine sprues for injecting coolant so that the coolant can cool the mold and the product inside the mold. However, the mold cavity of a router is generally more regular, and the design specifications of the mold water channel are generally limited. The cooling area of ​​the mold and the product is small, which is more inconvenient. In addition, when injecting coolant into the fine sprue, the coolant generally flows from the inlet through the water channel for heat exchange. After flowing out of the mold outlet, the coolant at the outlet may be higher than the liquid flow temperature at the inlet due to the continuous heat exchange, resulting in uneven coolant temperature in the fine sprue, which may cause uneven cooling of the product, which is more inconvenient.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 4 In the embodiment of the present invention, the router lower shell has a two-outlet structure, including a mold body 100, the mold body 100 includes a cooling mechanism 200 inside, and the cooling mechanism 200 is equipped with two heat exchange mechanisms 400;

[0022] The cooling mechanism 200 includes two conduits 210, and both conduits 210 are rectangular. A fixed tube 220 is fixedly connected between the two conduits 210, and the interior of the fixed tube 220 is connected to the interiors of the two conduits 210. L-shaped tubes 230 are fixedly connected to both ends of the two conduits 210, and the interiors of the four L-shaped tubes 230 are connected to the interiors of adjacent conduits 210. The two heat exchange mechanisms 400 on the same cooling mechanism 200 are respectively located inside the two conduits 210.

[0023] Specifically, multiple cooling mechanisms 200 are provided at different positions on the mold body 100, and the cooling mechanisms 200 are used to cool the mold body 100 and the product therein, thereby cooling the product in the one-out-two mold. The two conduits 210 are both rectangular, but the two ends of the same conduit 210 are not connected and do not touch. The user injects coolant into the cooling mechanism 200, and injects the coolant from the L-shaped tube 230 at the adjacent ends of the two conduits 210, so that the coolant flows through the two conduits 210 and then flows out from the L-shaped tube 230 at the opposite ends of the two conduits 210, thereby cooling the mold body 100 and the product therein. When flowing through the two conduits 210, the coolant can be converged through the connecting tube 300, and the connecting tube 300 is used to cool the mold portion between the two conduits 210, thereby increasing the cooling area of ​​the mold and the product therein, and improving the cooling effect of the mold and the product.

[0024] Example 1

[0025] like Figure 2-3As shown, in this embodiment, the outer walls of the two conduits 210 are fixedly sleeved with cooling pipes 211, the interior of the cooling pipes 211 is connected to the interior of the adjacent conduits 210, the inner diameter of the cooling pipes 211 is larger than the inner diameter of the conduits 210, and a connecting pipe 300 is fixedly connected between the two conduits 210, and the interior of the connecting pipe 300 is connected to the two conduits 210, and the inner diameter of the connecting pipe 300 is larger than the inner diameter of the conduits 210.

[0026] In this embodiment, no matter where the cooling pipe 211 is installed on the conduit 210, the cooling pipe 211 is in a perpendicular state to the conduit 210 to which it is connected. Since the flow direction of the coolant in the conduit 210 is fixed, the coolant can flow through the cooling pipe 211 to cool the product and the mold. The cooling pipe 211 is used to cool the rectangular peripheral area and the rectangular internal area formed by the conduit 210, thereby improving the cooling effect on the mold and the product. In addition, the two conduits 210 on the same cooling mechanism 200 can be connected through the connecting pipe 300 with a larger inner diameter, thereby improving the cooling effect of the area between the two conduits 210. During production, multiple cooling mechanisms 200 can be arranged on the mold according to actual needs, and different numbers of cooling pipes 211 and connecting pipes 300 can be added to each cooling mechanism 200 according to actual needs.

[0027] like Figure 3-4 As shown, in this embodiment, the heat exchange mechanism 400 includes a heat exchange tube 410, and the heat exchange tube 410 is located inside the adjacent guide tube 210, and both ends of the heat exchange tube 410 are fixedly connected to a hose 420, and the two hoses 420 are respectively located inside two adjacent L-shaped tubes 230, and the interior of the heat exchange tube 410 is connected to the interior of the two adjacent hoses 420, and a fixed cylinder 430 is provided at one end of the four L-shaped tubes 230, and the four fixed cylinders 430 are all open structures at both ends, the inner diameter of the opening at one end of the four fixed cylinders 430 is larger than the inner diameter of the opening at the other end, and the opening at one end of the four fixed cylinders 430 is fixedly connected to one end of the adjacent L-shaped tube 230, and the inner side wall of the other end opening is fixedly sleeved with the outer wall of the adjacent hose 420, the outer wall of the four fixed cylinders 430 is fixedly connected to the water injection cylinder 431, and the interior of the four water injection cylinders 431 is connected to the interior of the adjacent fixed cylinder 430.

[0028] In a specific implementation, when injecting coolant into the same cooling mechanism 200, the coolant is injected into the two L-shaped tubes 230 at the adjacent ends of the two conduits 210 using the water injection cylinder 431. Then, after the coolant flows along the adjacent conduits 210 through the fixed tube 220, the cooling tube 211 and the connecting tube 300, the coolant flows out from the L-shaped tube 230 at the opposite ends of the two conduits 210 through the adjacent water injection cylinder 431, thereby using the coolant to perform heat exchange between the mold and the product. At the same time, coolant is injected into the hose 420 at the opposite ends of the two conduits 210 so that the coolant enters the adjacent heat exchange tube 410. Then, the two heat exchange tubes 410 The internal coolant exchanges heat with the coolant inside the adjacent conduit 210, reducing the temperature of the coolant inside the conduit 210. The coolant in the two heat exchange tubes 410 then flows out from the two hoses 420 at the adjacent ends of the two conduits 210. Since the coolant in the two conduits 210 flows through a long area, when the liquid flows into the opposite ends of the two conduits 210, the temperature of the liquid there may be high after a long period of heat exchange. By injecting new coolant from the hoses 420 at the opposite ends of the two conduits 210, the new coolant cools the coolant in the conduits 210 with an excessively high temperature, thereby making the temperature of the liquid flow inside the conduits 210 more uniform.

[0029] Example 2

[0030] On the basis of the first embodiment, the rubber ring 440 is provided to ensure that the distance between the inner wall of the conduit 210 and the outer wall of the adjacent heat exchange tube 410 is equal.

[0031] like Figure 3-4 As shown, in this embodiment, multiple rubber rings 440 are movably sleeved on the outer wall of the heat exchange tube 410, and multiple abutment plates 441 are fixedly connected to the inner walls of the multiple rubber rings 440. One end of the multiple abutment plates 441 on the same rubber ring 440 is in contact with the outer wall of the adjacent heat exchange tube 410.

[0032] During specific implementation, the outer wall diameter of the rubber ring 440 is equal to the inner diameter of the conduit 210, so that the rubber ring 440 can be stuck inside the conduit 210, and multiple abutment plates 441 are used to support the heat exchange tube 410, so that the distance between the inner wall of the conduit 210 and the outer wall of the heat exchange tube 410 remains unchanged, so that the heat exchange tube 410 is always located in the center of the conduit 210, thereby improving the heat exchange efficiency between the liquid flow inside the heat exchange tube 410 and the liquid flow inside the conduit 210, and the liquid flow in the conduit 210 can flow out from the gap between the abutment plates 441.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
