Description

Technical Field

[0001] This utility model specifically relates to a mold limiting device. Background Technology

[0002] Glass molding lens technology has an extremely broad and bright future, with wide applications in fields such as micro-optics and integrated optics, biomedical imaging and sensing, small aircraft lidar, and advanced lighting. When compressing different molds, due to the varying diameters of the molds, it is necessary to replace the heating coils with matching ones for different mold models. Existing heating coils typically employ a modular structure, using bolts and other connectors to limit and fix the heating coil. However, this installation method leads to problems when changing to different mold models, such as the inability to install the heating coil or ensuring that the heating coil remains horizontal with the mold. This not only affects the heating effect but also increases the difficulty of disassembly. Utility Model Content

A mold adapter 22 is detachably installed on the top of the mold mounting part 21. A plurality of limiting holes 23 are circumferentially arrayed on the side wall of the mold adapter 22. In this embodiment, four sets of limiting holes 23 are used. The top of the adapter 22 is inserted into the mold body 24. The mold body 24 is limited to the top of the mold adapter 22 by the cooperation of the limiting hole 23 and the connector. A heating element is sleeved on the outside of the mold body 24. The heating element includes a heating coil 25, which is sleeved on the outer wall of the mold. The axis of the heating coil 25 is parallel to the axis of the mold. A coil terminal 26 is installed at the end of the heating coil 25, and the axis of the coil terminal 26 is parallel to the axis of the heating coil 25. Vertically, the coil terminal 26 passes through the clamping part. An adjusting bracket 3 is vertically mounted on one end face of the base 1. A clamping limiting component 4 is mounted on the side of the adjusting bracket 3. The clamping limiting component 4 moves longitudinally along the adjusting bracket 3 according to the height of the coil terminal 26 in the mold heating assembly 2, making the clamping part of the clamping limiting component 4 flush with a portion of the mold heating assembly 2. The portion of the mold heating assembly 2 is vertically inserted into the clamping part of the clamping limiting component 4, forming a limiting fixation. This is achieved by adjusting the clamping part of the base 1. The mold heating component 2 is mounted on the surface of the base 1. An adjusting bracket 3 and a clamping and limiting component 4 are mounted on the side of the base 1. By adjusting the bracket 3 and the clamping and limiting component 4, the position of the clamping and limiting component 4 clamping the mold heating component 2 can be adjusted to match mold heating components 2 of different heights. This can achieve clamping and limiting of heating coils 25 of different models of molds. Secondly, by using the adjustment block 41 and the clamping part to adjust the size of the placement slot, different heating coils 25 can be fixed, which facilitates the installation and removal of heating coils 25.

[0015] In a further embodiment, the adjusting bracket 3 includes a mounting plate 31, which is detachably mounted on the end of the base 1. Adjusting plates 32 are respectively mounted on both ends of the mounting plate 31. The adjusting plates 32 are integrally formed with the mounting plate 31 and are perpendicular to each other. Each set of adjusting plates 32 has a keyway 33 along its length direction, which penetrates the adjusting plate 32. The clamping and limiting component 4 is placed on the side of the adjusting plate 32 and connected to the adjusting plate 32 through the cooperation of the connector and the keyway 33. By adjusting the position of the clamping and limiting component 4 in the keyway 33, the height of the clamping and limiting component 4 can be adjusted so that the height of the clamping and limiting component 4 is adapted to the height of the mold heating coil 25.

[0016] In a further embodiment, the clamping and limiting assembly 4 includes an adjusting block 41. The lower end of the adjusting block 41 has a mounting hole 42 near the side wall of the adjusting bracket 3.

The clamping part includes a T-slider 45, which is divided into a mounting end and a sliding end. The sliding end of the T-slider 45 slides laterally into the adjusting bracket 3. Within the T-slot 43, the end of the T-shaped slider 45, together with the V-slot 44 and the T-slot 43, forms an adjustable placement groove. Connecting posts 46 are respectively installed on both sides of the mounting end of the T-shaped slider 45. Mounting posts 47 are respectively installed on the two sides of the adjusting block 41 away from the T-shaped slider 45. The mounting posts 47 and the connecting posts 46 are opposite each other. A limit spring 48 is installed between the mounting posts 47 and the connecting posts 46. The limit spring 48 is made of stainless steel. The elastic force of the limit spring 48 compensates for the normal force of the mold heating assembly 2 within the placement groove, meaning that when the mold needs to be changed: First, disassemble the mold body 24, then apply external force to the T-shaped slider 45 to stretch the limiting spring 48, so that the mold heating component 2 can be taken out from the placement slot. Then, install the replacement mold heating component 2 in the placement slot, and use the limiting spring 48 in conjunction with the T-shaped slider 45 to limit the mold heating component 2 in the placement slot. Then, install the mold body 24, so that the replacement of different models of mold bodies 24 can be realized.
