DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0021] See also Figures 1 to 5 In the present embodiment, a demoulding device for LCD display production is provided, including a base 1 and an adjusting plate 2. A placement groove is symmetrically provided on the upper end surface of the base 1. A first lead screw 11 is rotatably installed on the rear end surface of the placement groove through a bearing. A handle 12 is installed on the front end surface of the first lead screw 11. An adjusting slider is symmetrically screwed on the outer wall of the first lead screw 11. An adjusting plate 2 is installed on the upper end surface of the adjusting slider. A fixing frame 13 is installed on the upper end surface of the base 1. An adjusting cylinder 14 is installed on the top of the fixing frame 13. A demoulding mechanism 15 is arranged on the output end of the adjusting cylinder 14. When working, the mold is placed on the base 1, and the adjusting cylinder 14 is started to drive the demoulding mechanism 15 to move downward to demould the mold. When demoulding LCD display screens of different specifications, the handle 12 is rotated to drive the first lead screw 11 to rotate. The threads of the first lead screw 11 are symmetrical in front and back and in opposite directions, thereby driving the adjusting plate 2 to move inward and outward. The adjusting plate 2 limits the mold to avoid displacement of the mold during the demoulding process.

[0022] A fixing groove is provided on the upper end surface of the base 1, and a second lead screw 16 is rotatably installed on the right end surface of the fixing groove through a bearing. A first slider is screwed on the outer wall of the second lead screw 16, and a placement table 18 is installed on the upper end surface of the first slider. A plurality of placement cavities are provided on the upper end surface of the placement table 18, and a first motor 17 is installed on the left end surface of the second lead screw 16. When working, a plurality of molds are placed in the corresponding placement cavities, and the first motor 17 is started to drive the second lead screw 16 to rotate, so that the placement table 18 moves, and drives the mold to move to the corresponding demolding mechanism 15 directly below, so that a plurality of molds can be demolded.

[0023] A plurality of fixed suction cups 19 are embedded in the bottom of the placement cavity. When working, the fixed suction cups 19 are activated to attract and fix the bottom of the mold, thereby improving the stability of the connection between the mold and the placement cavity and avoiding the mold from jumping during demoulding.

[0024] The output end of the regulating cylinder 14 is provided with a connecting sleeve 21 , and the bottom of the connecting sleeve 21 is provided with a demoulding mechanism 15 by means of threaded rotation. When working, the demoulding mechanism 15 is conveniently disassembled and replaced by adopting a threaded connection.

[0025] The front end surface of the base 1 is symmetrically provided with a card cavity 22, in which a handle 12 is arranged. When working, the card cavity 22 protects the handle 12 to prevent the handle 12 from rotating due to accidental contact from the outside, causing the adjustment plate 2 to deviate.

[0026] The front end face of the base 1 is provided with a front groove, and a third lead screw 23 is rotatably installed on the left end face of the front groove through a bearing. The third lead screw 23 is symmetrical on the left and right and the thread directions are opposite. The third lead screw 23 is symmetrically screwed with a second slider on the left and right, and a connecting frame 24 is installed on the front end face of the second slider. The other end of the connecting frame 24 is connected to the card cavity 22. When working, the third lead screw 23 is manually rotated to drive the card cavity 22 to move inward, so that the handle 12 can be rotated to adjust the position of the adjustment plate 2, which is convenient for operation.

[0027] During specific operation, multiple molds are placed in the corresponding placement cavity, the first motor 17 is started, driving the second screw 16 to rotate, so that the placement table 18 moves, driving the mold to move to the bottom of the corresponding demolding mechanism 15, and the adjusting cylinder 14 is started to drive the demolding mechanism 15 to move downward to demold the mold. When demolding LCD display screens of different specifications, the handle 12 is turned to drive the first screw 11 to rotate. The front and rear symmetrical threads of the first screw 11 are in opposite directions, thereby driving the adjustment plate 2 to move inward and outward. The adjustment plate 2 limits the mold to avoid the mold from shifting during the demolding process.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. Structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the field unless otherwise specified and limited.
