Description

Technical Field

[0001] The utility model relates to the field of epoxy resin injection molding, in particular to an epoxy resin molding machine with good heat dissipation effect. Background Technique

[0002] Epoxy resin is a kind of high molecular polymer, which refers to the general name of a class of polymers containing more than two epoxy groups in the molecule. The excellent physical and mechanical properties, electrical insulation properties, adhesion properties with various materials, and the flexibility of its use process of epoxy resin are not possessed by other thermosetting plastics. Therefore, it can be made into coatings, composite materials, casting materials, adhesives, molding materials and injection molding materials, and is widely used in various fields of the national economy.

[0003] Epoxy resin materials are also widely used in the injection molding process. An injection molding machine, also known as an injection molding machine or an injection machine, pushes the melted thermoplastic material such as epoxy resin into the mold cavity by means of a feeding screw rod. After the high-temperature epoxy resin cools, the mold can be opened to obtain the plastic product formed by injection molding.

[0004] When the epoxy resin molding machine is working, the hot-melt epoxy resin is injected into the mold cavity and needs to be cooled before the injection-molded product can be obtained. Usually, in order to improve the cooling effect of the mold, a water circulation pipe is added inside the mold, and then the mold can be quickly cooled through the circulation of cooling water. Water cooling is faster than the natural cooling of the mold, but the cooling system of the injection molding process can still be improved, so that the production efficiency can be further improved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0030] The embodiments of the present utility model will be described below according to its overall structure.

[0031] An epoxy resin molding machine with good heat dissipation effect, as Figure 1-7 shown, includes an equipment cabin 1, a fixed mold 15 and an injection machine 17. Two groups of first telescopic components 6 are installed on one side of the equipment cabin 1, and the ends of the two groups of first telescopic components 6 are rotatably connected to a water circulation pipe 4. Gears 5 are installed outside the two water circulation pipes 4. A moving mold 2 is installed between the two water circulation pipes 4, and injection slots 3 are opened on both sides of the moving mold 2. Two groups of second telescopic components 7 are arranged on the top of the equipment cabin 1, and racks 8 are installed on the tops of the second telescopic components 7. The racks 8 and the gears 5 are meshed with each other. By setting the gears 5 and the racks 8, and injection slots 3 are arranged on both sides of the moving mold 2, when the moving mold 2 moves to withdraw the mold, it can rotate 180°, so that the two injection slots 3 can switch positions and be used alternately. That is, when one injection slot 3 is injecting, the other injection slot 3 can be continuously cooled. By extending the cooling time of the injection slot 3, the waste heat of the injection slot 3 can be better dissipated, which is convenient for the injection slot 3 to carry out the next injection work.

[0032] Please refer to Figure 3 , a third telescopic component 9 is installed on the side of the equipment cabin 1, and a pressing plate 10 is installed at the end of the third telescopic component 9. By setting the third telescopic component 9 to push the pressing plate 10 to fit the side of the moving mold 2, it can play a limiting role in the movement of the moving mold 2 and prevent its angle from deflecting.

[0033] Please refer to Figure 1 , a first limiting frame 11 is installed below the fixed mold 15 at the top of the equipment cabin 1. The first limiting frame 11 can play a limiting role on the moving mold 2. By setting the first limiting frame 11, it can play a limiting role on the moving mold 2 so that the moving mold 2 and the fixed mold 15 can fit more precisely.

[0034] Please refer to Figure 4 , a cover plate 12 is installed on the top of the equipment cabin 1, and a second limiting frame 13 is installed at the bottom of the cover plate 12. The second limiting frame 13 can play a limiting role on the moving mold 2. By setting the second limiting frame 13, it can play a limiting role on the moving mold 2 so that the moving mold 2 and the fixed mold 15 can fit more precisely.

[0035] Please refer to Figure 1 and Figure 4 , the fixed mold 15 is installed on the top of the cover plate 12 through an installation frame 14, and an injection machine 17 is arranged on the side of the installation frame 14. The injection machine 17 is installed on the top of the equipment cabin 1. By setting the fixed mold 15 and the injection machine 17, the molten epoxy resin can be injected into the injection slot 3 between the moving mold 2 and the fixed mold 15 through the injection machine 17.

[0036] Please refer to Figure 1 and Figure 3 At the top of the equipment cabin 1, a material box 16 is installed below the moving mold 2. By setting the material box 16, when the moving mold 2 demolds and discharges materials, the injection molded product can directly fall into the material box 16.

[0037] The working principle of the present utility model is as follows: Start the third telescopic component 9 and the first telescopic component 6. The first telescopic component 6 pushes the moving mold 2 towards the fixed mold 15 and fits with the fixed mold 15. During the movement of the moving mold 2, the second telescopic component 7 works to drive the rack 8 to descend so that the rack 8 does not mesh with the gear 5. And during the process of the moving mold 2 gradually approaching the fixed mold 15, the second limit frame 13 and the first limit frame 11 play a limiting role on the moving mold 2, and the third telescopic component 9 pushing the pressing plate 10 to fit with the moving mold 2 also plays a limiting role on the moving mold 2.

[0038] After the moving mold 2 and the fixed mold 15 are fitted, start the injection machine 17. The injection machine 17 injects the molten epoxy resin into the fixed mold 15, and then the molten epoxy resin flows into the injection molding groove 3. At the same time, start the cooling system connected to the water circulation pipe 4. After a period of cooling, start the third telescopic component 9 again so that the third telescopic component 9 drives the pressing plate 10 to quickly retreat, and then start the third telescopic component 9 to drive the moving mold 2 to slowly retreat. At the same time, start the second telescopic component 7 to drive the rack 8 to rise. Then, during the movement of the moving mold 2, the gear 5 and the rack 8 mesh with each other to drive the moving mold 2 to rotate 180°. When the moving mold 2 rotates 90°, the feeding device of the injection molding machine starts to clamp and place the injection molded part into the material box 16. According to the above, when the moving mold 2 works next time, the injection molding grooves 3 on both sides of the moving mold 2 have switched positions, and the two groups of injection molding grooves 3 are used alternately.
