Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mold cooling technology and relates to a novel auxiliary cooling device. Background Technology
[0002] During the production process, molds need to be cooled. Some high-precision molds that cannot be fitted with internal cooling pipes require auxiliary cooling devices, typically water cooling. Traditional auxiliary cooling tanks have a fixed inlet pipe at one end and a fixed drain pipe at the other. An external water pump pumps cooling water into the cooling tank through the inlet pipe. During cooling, temperature exchange occurs between the mold and the cooling water, and the heat exchange between the water flow and the heat source can create a temperature gradient. In addition, with the inlet pipe fixed, the cooling water tends to flow directly from the inlet pipe to the drain pipe, resulting in a faster water flow rate in that path and a slower flow rate in other areas. This uneven flow rate can lead to uneven heat transfer, with faster flow rates in some areas and slower flow rates in others, resulting in uneven heating and poor cooling performance.
[0003] Therefore, this utility model provides a novel auxiliary cooling device to solve the above problems. Utility Model Content
[0004] In view of the problems existing in the prior art, this utility model discloses a novel auxiliary cooling device. The technical solution adopted is as follows: a rectangular cooling tank with support columns at the four corners of the bottom; an L-shaped drain pipe with an electromagnetic valve is opened at the center of the bottom lower surface of the rectangular cooling tank; rectangular grooves are opened outward on the left and right side walls of the rectangular cooling tank; fixed columns are fixedly installed at the four corners of the upper surface of the bottom of the rectangular cooling tank; a mold placement groove is fixedly connected to the upper end of the fixed columns; a screw rod is rotatably sealed and installed in the bottom opening of the rectangular groove; rectangular lifting blocks are movably mounted on the left and right screw rods; the opposite ends of the left and right rectangular lifting blocks are fixedly connected to the left and right ends of a rectangular ring pipe by pipe clamps; several water spray pipes are evenly opened on the inner wall of the rectangular ring pipe; U-shaped water inlet pipes are fixedly connected upward at the left rear and right front two diagonals of the rectangular ring pipe; the other end of the U-shaped water inlet pipe is located on the outside of the rectangular cooling tank; the left and right screw rods are driven by a driving mechanism at the lower part of the rectangular cooling tank.
[0005] As a preferred embodiment of this utility model, the opposite ends of the left and right rectangular lifting blocks are respectively slidably inserted into the left and right rectangular grooves; this design ensures that the left and right rectangular lifting blocks can move up and down along the left and right rectangular grooves.
[0006] As a preferred embodiment of this utility model, water-permeable holes are respectively provided at the bottom and side walls of the mold placement groove.
[0007] As a preferred embodiment of this utility model, the rectangular annular tube is disposed in the gap between the inner wall of the rectangular cooling tank and the outer wall of the mold placement slot; this design avoids interference between the rectangular annular tube and the mold placement slot when the rectangular annular tube moves up and down along the inner wall of the rectangular cooling tank.
[0008] As a preferred embodiment of this utility model, the upper ends of the left and right lead screws are respectively rotatably inserted with rectangular fixing ears, and the left and right rectangular fixing ears are respectively fixedly installed in the left and right rectangular grooves.
[0009] As a preferred embodiment of this utility model, the driving mechanism includes sprockets that are fixedly connected to the left and right lead screws respectively. The left and right sprockets are connected by a set chain. The lower end of the left lead screw is fixedly connected to a motor. The motor body is fixedly mounted on a fixed plate. The front and rear sides of the fixed plate are fixedly mounted on the front and rear support columns.
[0010] The beneficial effects of this utility model are as follows: The motor drives the left lead screw to rotate, and the left lead screw drives the right lead screw to rotate synchronously through the lower sprocket and chain transmission. This enables the left and right rectangular lifting blocks to move up and down synchronously, which in turn drives the rectangular ring tube to move up and down along the inner wall of the rectangular cooling tank. With the help of the U-shaped water inlet pipe of the external water pump, cooling water is pumped into the rectangular ring tube and discharged at high speed through the water spray pipe in the inner ring of the rectangular ring tube. This makes the water in the rectangular cooling tank evenly cooled, avoiding the problem of uneven cooling caused by the large temperature gradient between the mold and the water inlet pipe in the traditional fixed water inlet pipe method. At the same time, the up and down moving rectangular ring tube further intensifies the tumbling flow of water in the rectangular cooling tank, thereby improving the temperature uniformity and cooling efficiency.

Detailed Implementation
[0016] Example 1
[0017] like Figures 1 to 4 As shown, the novel auxiliary cooling device of this utility model adopts the following technical solution: It includes a rectangular cooling tank 1 with support columns at its four corners. An L-shaped drain pipe 11 with an electromagnetic valve is opened at the center of the lower surface of the bottom of the rectangular cooling tank 1. Rectangular grooves 12 are respectively opened outwards on the left and right side walls of the rectangular cooling tank 1. Fixing columns 13 are fixedly installed at the four corners of the upper surface of the bottom of the rectangular cooling tank 1. A mold placement groove 2 is fixedly connected to the upper end of the fixing columns 13. Water permeable holes 21 are respectively opened at the bottom and side walls of the mold placement groove 2. A screw rod 14 is rotatably and sealingly installed at the bottom opening of the rectangular groove 12. Rectangular lifting blocks 15 are movably mounted on the left and right screw rods 14 respectively. The opposite ends of the left and right rectangular lifting blocks 15 slide and engage with the left and right rectangular grooves 12 respectively. The opposite ends of the left and right rectangular lifting blocks 15 are respectively fixedly connected to the left and right ends of a rectangular ring pipe 16 by pipe clamps. A plurality of water spray pipes 161 are evenly opened on the inner wall of the annular pipe 16. The left rear and right front two diagonals of the rectangular annular pipe 16 are respectively fixedly connected to U-shaped water inlet pipes 17. The other end of the U-shaped water inlet pipe 17 is set on the outside of the rectangular cooling tank 1. The upper ends of the left and right lead screws 14 are respectively rotatably inserted into rectangular fixing ears 18. The left and right rectangular fixing ears 18 are respectively fixedly installed in the left and right rectangular grooves 12. The left and right lead screws 14 are driven by a drive mechanism 3 at the lower end of the rectangular cooling tank 1. The drive mechanism 3 is installed in the lower part of the rectangular cooling tank 1. The drive mechanism 3 includes sprockets 31 fixedly connected to the left and right lead screws 14 respectively. The left and right sprockets 31 are connected by a sleeve chain 32. The lower end of the left lead screw 14 is fixedly connected to a motor 33. The body of the motor 33 is fixedly installed on a fixing plate 34. The front and rear sides of the fixing plate 34 are fixedly fitted on the front and rear support columns.
[0018] The working principle of this utility model is as follows: In use, the mold that needs to be cooled is placed on the mold placement slot 2 inside the rectangular cooling tank 1 by a hoisting machine, so that it is submerged in the cooling water inside the rectangular cooling tank 1. Then, the external water pump is connected to the left and right U-shaped water inlet pipes 17, and the motor 33 is controlled to rotate. The motor 33 drives the left lead screw 14 to rotate. The left lead screw 14 drives the right lead screw 14 to rotate synchronously through the lower sprocket 32 and chain 33, thereby realizing the synchronous up and down movement of the left and right rectangular lifting blocks 15. This drives the rectangular ring pipe 16 to move up and down along the inner wall of the rectangular cooling tank 1. With the help of the U-shaped water inlet pipe 17 of the external water pump, the cooling water is pumped into the rectangular ring pipe 16 and discharged at high speed through the spray pipe 161 of the inner ring of the rectangular ring pipe 16. At the same time, the electromagnetic valve of the L-shaped drain pipe 11 is controlled so that the cooling water heated by the heat source is gradually discharged, thereby making the water in the rectangular cooling tank 1 uniformly cooled and improving the uniformity of mold cooling.
