Technical Field

[0001] The utility model relates to the technical field of LED lamp cup production, in particular to an LED lamp cup injection mold. Background Art

[0002] The name of the lamp cup comes from the fact that it imitates the shape of the entire lamp body like a funnel. This design allows the lamp body to be tightly connected to the bottom of the lamp head, while also protecting the wick and playing a role in focusing light. With the advancement of technology, we gradually find that lamp cups made of plastic have been used more and more widely because of their lightness and durability. In the process of making lamp cups, injection molds play a vital role.

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.

[0030] See also Figure 1-4 An LED lamp cup injection mold includes a base plate 100, a compressor 200, a cooling box 300, a lower mold 400 and a bottom support plate 500.

[0031] Support plates 101 are fixedly connected to both ends of the lower surface of the bottom plate 100. The compressor 200 is arranged on the lower surface of the bottom plate 100. The connection port of the compressor 200 is fixedly connected to an S-shaped condenser tube 201. The cooling box 300 is arranged on the upper surface of the bottom plate 100. The S-shaped condenser tube 201 is arranged inside the cooling box 300. The lower mold 400 is arranged on the upper surface of the bottom plate 100. A spiral groove 401 is opened in the side wall of the lower mold 400, and the spiral groove 401 is connected to the S-shaped condenser tube 201.

[0032] The bottom support plate 500 is arranged at the bottom of the lower mold 400. The lower surface of the bottom support plate 500 is fixedly connected with a sliding rod 501. The sliding rod 501 is slidably plugged into the bottom end of the lower mold 400, and the sliding rod 501 passes through the surface of the bottom plate 100.

[0033] After the lower mold 400 is fixedly installed on the upper surface of the base plate 100, the S-shaped condenser 201 will be connected to the spiral groove 401 opened around the side wall of the lower mold 400, and the coolant circulation is realized between the S-shaped condenser 201 and the spiral groove 401 through the compressor 200. When the coolant brings the heat in the lower mold 400 to the S-shaped condenser 201, the S-shaped condenser 201 can be quickly cooled inside the nozzle 303, so that when the coolant in the S-shaped condenser 201 re-enters the spiral groove 401, heat exchange is realized on the lower mold 400, so that the LED lamp cup inside the lower mold 400 is quickly cooled and shaped.

[0034] After the LED lamp cup inside the lower mold 400 is cooled and formed, the movable bottom support plate 500 can push the LED lamp cup out from the interior of the lower mold 400, making it convenient to collect the finished LED lamp cup.

[0035] For further preference, see Figure 1 、 Figure 2 Two limiting frames 102 are fixedly connected to the upper surface of the base plate 100. The two limiting frames 102 are located on either side of the lower mold 400. Fastening bolts 103 are threadedly connected to the surfaces of the limiting frames 102. The ends of the fastening bolts 103 are in contact with the surface of the lower mold 400. The lower mold 400 can be placed between the two limiting frames 102 and the fastening bolts 103 are tightened to fix the lower mold 400 in place.

[0036] For further preference, see Figure 1 、 Figure 2 and Figure 4 The end of the S-shaped condenser tube 201 is fixedly connected to 202. The side wall of the lower mold 400 is provided with an interface 402. The spiral groove 401 is connected to the interface 402. The interface 402 corresponds to the position of 202. The coolant in the S-shaped condenser tube 201 can be passed into the interior of the spiral groove 401 through the interface 402, realizing water circulation.

[0037] For further preference, see Figure 2 、 Figure 3 A nozzle 303 is fixedly connected to the top wall of the cooling box 300. A water pipe 304 is fixedly connected to the connection port of the nozzle 303. The bottom end of the water pipe 304 is fixedly connected to a water pump 305. The water pump 305 is located at the bottom end of the cooling box 300. The water pump 305 can extract water from the bottom of the cooling box 300 and spray it onto the surface of the S-shaped condenser tube 201 through the nozzle 303.

[0038] For further preference, see Figure 1 、 Figure 2 A breathable and waterproof curtain 301 is fixedly connected to one side of the cooling box 300, and a cooling unit 302 is fixedly connected to the other side of the cooling box 300. The breathable and waterproof curtain 301 and the cooling unit 302 form convection within the cooling box 300, cooling the S-shaped condenser tube 201. At the same time, the water on the surface of the S-shaped condenser tube 201 can increase the cooling rate of the S-shaped condenser tube 201.

[0039] For further preference, see Figure 2 、 Figure 3 and Figure 4 The bottom end of the base plate 100 is fixedly connected to an electric telescopic rod 600, which is also fixedly connected to an adjustment plate 601. The bottom end of the slide rod 501 is fixedly connected to the adjustment plate 601 via screws 502. The electric telescopic rod 600 drives the adjustment plate 601 to move, which in turn drives the bottom support plate 500 to move inside the lower mold 400, thereby conveniently ejecting the LED lamp cup formed and fixed inside the lower mold 400.
