Description

Technical Field

[0001] The utility model belongs to the technical field of optical lenses, and in particular relates to a molding device for optical plastic lenses. Background Art

[0002] After lenses are formed using conventional compression molds, their outer diameter cannot be effectively controlled. Therefore, after the lenses are formed, they need to undergo an edging process to adjust the outer diameter of the lenses and process them to within the specifications of the drawings. However, the additional edging process can easily lead to defects such as chipping around the lens, surface pinching, and outer diameter fluctuations, which increases the product defect rate, greatly affects the production quality of the products, increases the processing cost of the lenses, and greatly delays the lens production process.

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.

[0015] The utility model provides Figure 1-2 The molding device for an optical plastic lens shown in the figure includes an upper mold core 100 and a lower mold core 300 arranged in correspondence with each other. An outer mold sleeve 200 is provided on the outer periphery of the upper mold core 100 and the lower mold core 300. The left and right sides of the outer mold sleeve 200 are provided with mounting channel 1 210 and mounting channel 220 from top to bottom. The lower end of the upper mold core 100 is provided with an upper molding surface 110, and the upper end of the lower mold core 300 is connected to the mold core 310. The upper end of the mold core 310 is provided with a lower molding surface 320. The upper mold core 100, the lower mold core 300, the outer mold sleeve 200 and the mold core 310 are all cylindrical. A circular ring 1 400 and a circular ring 2 410 are provided between the mold core 310 and the outer mold sleeve 200.

[0016] Among them, the mold core 310 is fixedly connected to the upper end of the lower mold core 300, and the thickness of the lower end of the ring 2 410 matches the distance between the mold core 310 and the outer mold sleeve 200, thereby preliminarily limiting the position of the ring 2 410. The diameter of the lower end of the upper mold core 100 matches the inner diameter of the outer mold sleeve to prevent it from shaking and improve the accuracy of the molding.

[0017] In some specific embodiments of the present invention, the left and right sides of the lower mold core 300 are provided with mounting channels 220 corresponding to the outer mold sleeve 200, and the left and right sides of the rings 1 400 and 2 410 are provided with mounting channels 1 210 corresponding to the outer mold sleeve 200.

[0019] In some specific embodiments of the present invention, the first installation hole 210 passes through the outer mold sleeve 200 and the first ring 400 but does not pass through the second ring 410 , and the second installation hole 220 passes through the outer mold sleeve 200 but does not pass through the lower mold core 300 .

[0020] In some specific embodiments of the present invention, threads are provided on the inner walls of the first mounting hole 210 and the second mounting hole 220 .

[0021] By setting the threads, the corresponding screw rods can be used to respectively install or remove the ring 1 400, the ring 2 410 and the lower mold core 300.

[0022] When in use, the lower mold core 300 and the mold core 310 are fixed in the outer mold sleeve 200 using the screw corresponding to the mounting channel 220, and then the ring 1 400 is placed on the mold core 310. According to the outer diameter of the lens to be molded, a suitable ring 2 410 is selected and placed on the mold core 310, and the screw corresponding to the mounting channel 1 210 is used to fix the ring 1 400 and the ring 2 410, and then the molding is carried out.
