Description

Technical Field

[0001] This invention relates to the field of injection mold technology, specifically to high-efficiency injection molds for resin lenses. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding are fast production speed, high efficiency, automated operation, a wide variety of colors and shapes, shapes ranging from simple to complex, sizes ranging from large to small, precise product dimensions, easy product updates and replacements, and the ability to produce complex-shaped parts. Injection molding is suitable for mass production and molding processing fields such as complex-shaped products.

[0003] Injection molds are used in many product molding fields, and resin lenses also utilize injection mold technology in their production process. While existing injection mold technology is quite comprehensive, it still has certain shortcomings in practice.

[0004] 1. In the existing injection mold production of resin lenses, due to the weight of the resin lenses, they will fall off by their own weight during the mold opening process. Therefore, manual handling is required to pick up the products during the mold opening process, which is time-consuming and labor-intensive, and greatly reduces the efficiency of mold opening.

[0005] 2. Existing injection molds require cooling after injection. The product in the mold can only be demolded after it has cooled and solidified. Existing liquid cooling technology for injection molds is widely used. However, existing liquid cooling technology has high power requirements for circulation pumps. In order to speed up the circulation rate, high-power circulation pumps are needed, which increases the cost of equipment use.

[0006] 3. Most existing injection molds use liquid cooling, which has a poor heat dissipation rate and a relatively simple heat dissipation method, reducing the heat dissipation efficiency of the equipment and thus reducing the production efficiency of the products. Summary of the Invention

The heat collection plate 604 is installed on the top of one side of the first mold 12 and the second mold 13.The mounting platform 1 is equipped with two fixed plates 3 symmetrically mounted on the other side of its top. Each fixed plate 3 has two mounting plates 4 mounted on its top. A first telescopic cylinder 5 and a second telescopic cylinder 7 are symmetrically mounted on the top of the four mounting plates 4. The output end of the first telescopic cylinder 5 is fixedly connected to a second mold 13, and the output end of the second telescopic cylinder 7 is fixedly connected to a first mold 12. The first mold 12 and the second mold 13 are fitted together on opposite sides, facilitating the opening and closing of the molds via the first telescopic cylinder 5 and the second telescopic cylinder 7.

This facilitates buffering of the material discharge through the material discharge buffer mechanism 2. Four support legs 10 are symmetrically installed at the four corners of the bottom of the mounting platform 1.

[0030] Working principle: During use, the first telescopic cylinder 5 and the second telescopic cylinder 7 are first opened, and their output ends extend, thereby driving the first mold 12 and the second mold 13 to move relative to each other and close the mold. After mold closing, resin is injected into the cavity between the first mold 12 and the second mold 13 using the injection nozzle. At this time, the circulating cooling mechanism 8 is opened, and the circulating water pump 805 in the circulating cooling mechanism 8 starts working, pumping the coolant in the water tank 802 through the water outlet pipe 803. The coolant is delivered to the split inlet hose 807, and then enters the cooling channels 806 inside the first mold 12 and the second mold 13 to absorb the heat generated during injection molding. The heat-absorbing coolant then enters the delivery hose 804, and subsequently falls from the delivery hose 804 into the transfer water tank 601. As the coolant falls into the transfer water tank 601, it drives the water drive spoon 610 to rotate, which in turn drives the connecting pin 609 to rotate, which in turn drives the second mounting head 608 to rotate, and then drives the rotating shaft 606 to rotate, which in turn drives the first... When the mounting head 603 rotates, it drives the heat dissipation blades 602 to rotate. The rotation of the heat dissipation blades 602 generates airflow, which carries away the heat from the heat collection plate 604 and the heat dissipation fins 605, achieving air cooling and improving heat dissipation efficiency. Furthermore, the circulating heat dissipation mechanism 8 is linked to the air cooling mechanism 6, eliminating the need for external power to drive the air cooling mechanism 6, thus improving the practicality of the equipment. The coolant in the transfer water tank 601 enters the diversion return water hose 809, then enters the circulating return water pipe 808, and then flows through the circulating return water pipe 80... 8. The coolant flows back into the water tank 802 to form a liquid cooling circulation for heat dissipation. Since the height of the water tank 802 is higher than that of the first mold 12 and the second mold 13, it makes full use of gravitational potential energy, reduces the dependence on the power of the circulating water pump 805, and reduces energy consumption. The feed hopper 801 is used for adding coolant. The base plate 9 is used to fix the water tank 802. The support leg 10 is used to fix the mounting platform 1. The fixing plate 3 is used to fix the mounting plate 4. The mounting plate 4 is used to fix the first telescopic cylinder 5 and the second telescopic cylinder 7. The fixing block 607 is used to fix the rotating shaft 606.
