Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass forming technology, and in particular to a demolding mechanism for glass forming. Background Technology
[0002] A glass hot bending machine is one type of glass forming equipment. It works by placing glass cut to a specified shape into a mold, then sequentially feeding the mold into a preheating station, a forming station, a slow cooling station, and a cooling station before finally demolding. At the forming station, the heated glass is shaped using the upper and lower molds.
[0003] In the actual molding process, the upper mold needs to be removed manually, the glass to be molded needs to be placed on the lower mold, and finally the upper mold is placed back on the lower mold with the glass, before being sent to the preheating station. This process requires manual removal of the upper mold from the lower mold, manual placement of the glass to be molded onto the lower mold, and manual replacement of the upper mold. This glass loading and unmolding action is entirely manual, which is labor-intensive. Moreover, since the glass needs to be aligned and positioned with the lower mold by hand, the removed upper mold needs to be put down, and after the glass is positioned on the lower mold, the upper mold needs to be picked up again and placed back on the lower mold with the glass. This requires quick coordination of both hands, making the operation cumbersome. Utility Model Content
[0004] The purpose of this invention is to provide a demolding mechanism for glass forming, addressing the shortcomings and deficiencies of existing technologies.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] The present invention discloses a demolding mechanism for glass forming, comprising a support frame, an upper mold clamping assembly, and a moving assembly for driving the upper mold clamping assembly to move; the upper mold clamping assembly includes a housing; at least one clamping element is provided inside the housing; the clamping element includes two clamping plates and two symmetrically arranged telescopic components; each of the housings has an opening slot at a position directly opposite the telescopic components; one end of each telescopic component is fixed inside the housing; the other ends of the two telescopic components extend from the opening slots to the outside of the housing and are fixedly connected to the two clamping plates.
[0007] Furthermore, the clamping plate is L-shaped; the clamping plate is fixed to the telescopic assembly; the two clamping plates on the same clamping element are arranged opposite each other at the ends away from the telescopic assembly.
[0008] Furthermore, the moving component includes a horizontal linear module and a vertical linear module; one end of the horizontal linear module is fixed to the upright support; the other end of the horizontal linear module is fixed to one end of the vertical linear module; and the other end of the vertical linear module is fixed to the housing.
[0009] Furthermore, the telescopic component is a cylinder.
[0010] Furthermore, the number of clamping elements is any one of two, three, or four; the clamping elements are distributed circumferentially on the housing.
[0011] With the above structure, the beneficial effects of this utility model are as follows: the moving component moves the housing to a position above the upper mold, so that the bottom end of the clamping plate is aligned with the upper mold. Then, the two telescopic components of the clamping element move synchronously, so that the two clamping plates are clamped. Then, the moving component lifts the housing, so that the upper mold separates from the lower mold and is transported to a position that is misaligned with the lower mold. After the cut lens is placed into the lower mold by the operator, the moving component moves the housing to cover the lower mold with the lens. After the mold is closed, it is transported to the next station by an external robot. In this structure, the demolding of the upper mold does not require manual operation during the lens feeding process, reducing labor intensity. Moreover, when the lens is fed, there is no need to put down the upper mold. Both hands only need to operate on the lens, making lens feeding more convenient. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings.
[0018] like Figures 1 to 2 As shown, the demolding mechanism for glass forming according to this utility model includes a support frame 1, an upper mold clamping assembly, and a moving assembly for driving the upper mold clamping assembly to move; the upper mold clamping assembly includes a housing 5; at least one clamping element is provided inside the housing 5; the clamping element includes two clamping plates 6 and two symmetrically arranged telescopic components 4; the housing 5 is provided with an opening slot 501 at the position directly opposite the telescopic components 4; one end of the telescopic component 4 is fixed inside the housing 5; the other ends of the two telescopic components 4 extend from the opening slot 501 to the outside of the housing 5 and are fixedly connected to the two clamping plates 6;
[0019] The movable component can drive the box 5 to move up and down and horizontally, and can lift the upper mold and move it to a position that is misaligned with the lower mold. The box 5 is made of heat insulation material. The heat insulation of the box 5 can make the temperature inside the box 5 more stable and the operation of the telescopic component 4 more stable. Each telescopic component 4 is connected to a clamping plate 6.
[0020] The moving component moves the housing 5 to a position above the upper mold 7, aligning the bottom of the clamping plate 6 with the upper mold 7. Then, the two telescopic components 4 holding the clamping element move synchronously, clamping the two clamping plates 6. The moving component then lifts the housing 5, separating the upper mold 7 from the lower mold 8 and transporting the upper mold 7 to a position misaligned with the lower mold 8. After the cut lens is manually placed into the lower mold 8, the moving component moves the housing 5 to cover the lower mold 8 with the lens, completing the mold closing. Afterward, the upper mold 7 is transported to the next station by an external robotic arm. In this structure, the demolding of the upper mold 8 does not require manual operation during the lens insertion process, reducing labor intensity. Moreover, when inserting the lens, there is no need to lower the upper mold; both hands only need to operate on the lens, making lens loading more convenient.
[0021] In a preferred embodiment of this utility model, the clamping plate 6 is L-shaped; the clamping plate 6 is fixed on the telescopic assembly 4; the two clamping plates 6 on the same clamping element are arranged opposite each other at the ends away from the telescopic assembly 4;
[0022] The L-shaped clamping plate 6 structure allows the end of the clamping plate 6 to extend into the bottom of the box 5, and can clamp the upper mold which is smaller than the width of the box 5.
[0023] In a preferred embodiment of this utility model, the moving component includes a horizontal linear module 2 and a vertical linear module 3; one end of the horizontal linear module 2 is fixed to the upright bracket 1; the other end of the horizontal linear module 2 is fixed to one end of the vertical linear module 3; and the other end of the vertical linear module 3 is fixed to the housing 5.
[0024] Both the horizontal linear module 2 and the vertical linear module 3 include a lead screw, a lead screw nut, a guide rail, a slider, and a motor. The lead screw nut is fixed to the slider, and the lead screw is threadedly connected to the lead screw nut. The motor drives the lead screw to rotate, which can push the lead screw nut to move along the length of the guide rail, realizing the horizontal or vertical linear motion. This is not fundamentally different from the existing technology, so it will not be described in detail. The horizontal linear module 2 can drive the vertical linear module 3 to perform translational motion on the support 1, while the vertical linear module 3 can drive the housing 5 to perform vertical motion, realizing the translational and vertical motion of the clamping element.
[0025] In a preferred embodiment of this utility model, the telescopic component 4 is a cylinder.
[0026] In a preferred embodiment of this utility model, the number of clamping elements is any one of two, three, or four; the clamping elements are distributed circumferentially on the housing 5; the number of clamping elements is set according to the shape and weight of the upper mold 7 to be clamped.
