Description

Technical Field

[0001] This utility model relates to the field of mold cooling, and in particular to an improved cooling mechanism for the molding of thermosetting thin-walled parts. Background Technology

[0002] Currently, after the thermosetting plastic thin-walled parts are molded and cooled, the embedded parts may experience delamination. This is because the embedded parts include a core rod and magnetic sheets, with multiple magnetic sheets arranged around the outer periphery of the core rod. The thermosetting plastic thin-walled parts are attached to these magnetic sheets, which are usually glued to the outer periphery of the core rod. However, because the adhesive is easily melted when heated, the magnetic sheets may fall off the core rod or their position on the core rod may change. As a result, the thermosetting plastic thin-walled parts and the numerous magnetic sheets cannot adhere well, and the production process does not meet the requirements. Utility Model Content

[0030] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] like Figure 1 and Figure 2 and Figure 3 As shown, an improved cooling mechanism for thermosetting thin-walled parts includes a central column 1 and a water collection block 2. The central column 1 is connected to the water collection block 2. The central column 1 is provided with a first threaded water passage 11 and a second threaded water passage 12. The first threaded water passage 11 and the second threaded water passage 12 are provided on the outer surface of the central column 1. The water collection block 2 is provided with an inlet pipe 21 and an outlet pipe 22. The inlet pipe 21 is connected to the first end of the first threaded water passage 11, and the outlet pipe 22 is connected to the first end of the second threaded water passage 12. Both the inlet pipe 21 and the outlet pipe 22 are connected to a cooling device (not shown in the figure).

[0032] The second end of the first threaded water passage 11 is connected to the second end of the second threaded water passage 12. The inlet pipe 21 and the outlet pipe 22 are used for circulating liquid. The central column 1 is used to fit the embedded part 9. The embedded part 9 includes a core rod 91 and a magnetic sheet 92. Multiple magnetic sheets 92 are fixed to the outer surface of the core rod 91 by adhesive.

[0033] The central column 1 is fitted inside the core rod 91, and the inner wall of the core rod 91 is in contact with the outer surface of the central column 1. In this way, the first threaded water passage 11 and the second threaded water passage 12 are sealed by the inner wall of the core rod 91. The outer surface of the magnetic sheet 92 is used to fit the injection-molded hollow plastic 8.

[0034] The coolant enters the first threaded water passage 11 from the inlet pipe 21, then enters the second threaded water passage 12, and finally returns to the cooling equipment from the outlet pipe 22. In this way, the coolant carries away the heat from the mandrel 91 during injection molding during the circulation process, so that the temperature of the mandrel 91 does not rise, the glue on the mandrel 91 will not melt, the magnetic sheet 92 will not fall off the mandrel 91, and the position of the magnetic sheet 92 on the mandrel 91 will not move.

[0035] A first pad 3 and a second pad 4 are respectively provided at both ends of the central column 1. The first pad 3 is located between the end of the central column 1 and the water collection block 2. The liquid inlet pipe 21 and the liquid outlet pipe 22 pass through the first pad 3. The second pad 4 is connected to the end of the central column 1 by a second screw 6. The second pad 4 and the central column 1 are fixed together by the second screw 6.

[0036] The first pad 3 has a first concave ring 31 and a first convex surface 32. The first concave ring 31 is arranged around the first convex surface 32. The first concave ring 31 is used to abut against the first end of the embedded part 9, that is, the first concave ring 31 is used to abut against the first end of the core rod 91. The core rod 91 is a hollow rod. The first convex surface 32 is used to press against the first end face of the central column 1. In this way, the first pad 3 can seal the first end face of the core rod 91 and the central column 1, and the coolant in the first threaded water channel 11 and the second threaded water channel 12 will not overflow from the first pad 3.

[0037] The first pad 3, the central column 1, and the water collecting block 2 are connected by a first screw 5. The water collecting block 2 is provided with a first guide rod 23 and a second guide rod 24. The first end of the central column 1 is provided with a first guide hole 13 and a second guide hole 14. The first guide rod 23 and the second guide rod 24 pass through the first pad 3. The first guide rod 23 is sleeved in the first guide hole 13, and the second guide rod 24 is sleeved in the second guide hole 14. This enables rapid positioning between the central column 1, the water collecting block 2, and the first pad 3.

[0038] The receiving groove 29 has a collar 20, and the first pad 3 is provided with a positioning groove 33. The collar 20 is sleeved in the positioning groove 33. When the first pad 3 is to be installed into the receiving groove 29, the positioning groove 33 should be sleeved on the collar 20. This further restricts the movement of the first pad 3 and makes the positioning groove 33 and the collar 20 more tightly fixed together.

[0039] like Figure 4 and Figure 5 and Figure 6 As shown, the inlet pipe 21 and the outlet pipe 22 pass through both ends of the water collection block 2. The outer port of the inlet pipe 21 is provided with a first flange joint 25, and the outer port of the outlet pipe 22 is provided with a second flange joint 26. The first flange joint 25 and the second flange joint 26 are connected to external cooling equipment to realize coolant circulation.

[0040] A ring groove 10 is provided on the central column 1. The second end of the first threaded water channel 11 and the second end of the second threaded water channel 12 are both connected to the ring groove 10. The first threaded water channel 11 and the second threaded water channel 12 are arranged around the outer surface of the central column 1.

[0041] The bottom of the water collection block 2 is provided with a first support rod 27 and a second support rod 28. The first support rod 27 is connected to the liquid inlet pipe 21 and provides support for the liquid inlet pipe 21. The second support rod 28 is connected to the liquid outlet pipe 22 and provides support for the liquid outlet pipe 22. The first support rod 27 and the second support rod 28 extend into the water collection block 2, so that the first support rod 27 and the second support rod 28 also provide support for the water collection block 2. The first support rod 27 and the second support rod 28 form an angle in the direction of extension.

[0042] like Figure 7 As shown, the water collection block 2 is provided with a receiving groove 29, and the first pad 3 is located in the receiving groove 29, so that the first pad 3 is not easy to move when it is fixed.

[0043] The second pad 4 has a second concave ring 41 and a second convex surface 42. The second concave ring 41 is arranged around the second convex surface 42. The second concave ring 41 is used to abut against the second end of the embedded part 9, that is, the second concave ring 41 abuts against the second end of the core rod 91. The second convex surface 42 is used to press against the second end face of the central column 1, so as to seal the second end face of the central column 1 and prevent coolant from overflowing.

[0044] like Figure 8 As shown, a base 7 is provided to cooperate with the first pad 3, the second pad 4 and the water collection block 2. The base 7 is provided with a groove 70, and the first pad 3, the second pad 4 and the water collection block 2 are placed in the groove 70.
