Description

Technical Field

[0001] The utility model relates to the technical field of glass magnesium plate production, in particular to a demoulding device for glass magnesium plate blanks. Background Art

[0002] Glass magnesium board is made of magnesium oxide, magnesium chloride and other materials as the main materials, reinforced with glass fiber mesh cloth, and mixed with water, perlite, wood chips and several other chemical additives into slurry and rolled into boards. When glass magnesium board is produced, it will be cast using a forming mold. After the raw materials are cooled and solidified, the glass magnesium board blank is formed. After demolding, the glass magnesium board can be obtained after the film is cleaned. The common demolding method of glass magnesium board is to first open the mold cover of the forming mold, put it upside down on the top press, fix the mold, and finally use the top press to punch the top, so that the blank is separated from the bottom plate of the mold, and the blank is demolded. However, the applicant believes that this common type of demolding method has the following shortcomings:

[0003] Since the top press has great force and a small contact area with the glass-magnesium board blank, the glass-magnesium board blank is easily damaged during the top press demoulding process. Utility Model Content

[0006] Preferably, slide rails are fixedly provided on both sides of the inner wall of the demoulding frame, and the demoulding pressing plate is slidably provided on the slide rails, so that the sliding demoulding is smooth.

[0007] Preferably, the blank plate mold includes a forming mold frame and a bottom mold plate snap-fitted at the bottom of the forming mold frame, and a demoulding hanging ring is fixedly provided on the forming mold frame. The demoulding hanging ring and the hook assembly are arranged one by one, with a simple structure and easy use.

[0008] Preferably, locking screws are rotatably provided on both sides of the bottom template, and locking screw plates are threadedly connected to the locking screws. Fixed sockets are fixedly provided on both sides of the forming mold frame. The locking screws and the fixed sockets are arranged one by one opposite to each other, so that the forming mold frame and the bottom template can be quickly spliced, which is convenient for the assembly and use of the blank mold.

[0020] When in use, the demoulding spring 12 and the demoulding push rod 7 are used to push the blank at multiple points at the same time to realize the separation of the glass magnesium board blank from the mold. The contact area with the glass magnesium board during the demoulding process is larger, thereby reducing the probability of damage to the glass magnesium board during the demoulding process, and the demoulding efficiency is high, saving time and effort.

[0021] See also Figure 1 , Figure 2 and Figure 4 Furthermore, the blank mold 3 includes a molding mold frame 31 and a bottom mold plate 32 which is clamped at the bottom of the molding mold frame 31. A demoulding ring 33 is fixedly provided on the molding mold frame 31. The demoulding ring 33 is arranged opposite to the hook assembly 10 one by one. Locking screws 35 are rotatably provided on both sides of the bottom mold plate 32. Locking screw plates 37 are threadedly connected to the locking screws 35. Fixed bases 36 are fixedly provided on both sides of the molding mold frame 31. The locking screws 35 and the fixed bases 36 are arranged opposite to each other one by one. Carrying handles 34 are fixedly provided at both ends of the molding mold frame 31.

[0022] When in use, rotate the locking screw disk 37 in sequence to make it away from the fixed base 36, then rotate the locking screw 35 to make it detach from the fixed base 36, and hang the hook assembly 10 on the demoulding hanging ring 33. During the lifting process, the hook assembly 10 pulls the forming mold frame 31 upward. At this time, since the bottom of the blank mold 3 has no support, under the elastic force of the demoulding spring 12, the pressing plate 9 will push the glass magnesium board to move downward in the forming mold frame 31, thereby separating from the forming mold frame 31 together with the bottom mold plate 32, and completing the demoulding of the glass magnesium board blank.

[0023] See also Figure 1 Furthermore, a switch plate 8 is fixedly provided on one side of the demolding frame 2, a lifting switch is fixedly installed on the surface of the switch plate 8, the electric-controlled hydraulic cylinder 6 is electrically connected to the external power supply through the lifting switch, and anti-slip foot pads 13 are fixedly provided on the four corners of the bottom end of the demolding base 1.

[0025] When the embodiment of the present application is used: after the glass magnesium board blank is cast and formed, the blank board mold 3 is placed on the demoulding base 1 by holding the carrying handle 34 so that it is directly opposite to the demoulding pressing plate 5, and then the locking screw disc 37 is rotated in sequence to make it away from the fixed clamping seat 36, and then the locking screw 35 is rotated to make it disengage from the fixed clamping seat 36, and then the lifting switch is pressed. At this time, the electric hydraulic cylinder 6 will push the demoulding pressing plate 5 to slide downward along the slide rail 4 and close to the blank board mold 3, and then the hook assembly 10 is hung on the demoulding hanging ring 33. During the process, the blank pressing plate 9 is in uniform contact with the top of the glass magnesium board, and squeezes the demoulding spring 12 to contract. At the same time, the demoulding push rod 7 slides upward, and then the electric hydraulic cylinder 6 contracts and resets. During the contraction and reset of the electric hydraulic cylinder 6, the forming mold frame 31 will be pulled upward through the hook assembly 10. At this time, since the bottom of the blank mold 3 has no support, under the elastic force of the demoulding spring 12, the blank pressing plate 9 will push the glass magnesium board to move downward in the forming mold frame 31, thereby separating from the forming mold frame 31 together with the bottom mold plate 32, and completing the demoulding of the glass magnesium board blank.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
