Description

Technical Field

[0001] The utility model relates to the technical field of dispensing, in particular to a dispensing mold which is convenient for demolding. Background Art

[0002] Dispensing is a process in industrial production. It precisely drops, coats or infuses glue, liquid materials, etc. onto specific positions to achieve purposes such as bonding, sealing, filling, and coating. The application scope of dispensing is very wide. From large aircraft and ships to small items like clothes and toys in production, dispensing may be required. It can be said that wherever glue reaches, the dispensing process service is needed. During the process of repairing and replacing a mobile phone screen, it is necessary to reapply glue around the bracket and then bond it with the new screen. During the glue application process, a dispensing mold is required to control the flow and formation of the glue. The dispensing mold has a specific shape and structure, which can accurately guide the glue to the designated position according to the design requirements of the product and form the expected glue pattern, significantly improving the accuracy and consistency of dispensing, making the effect of each dispensing tend to be the same, thus ensuring the stability of product quality.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 to 5 , the present utility model provides a technical solution:

[0026] A dispensing mold convenient for mold removal includes a mold body 1. The mold body 1 is a rectangular frame structure. Placement grooves 2 are provided around the top of the mold body 1. It also includes a base 3. An installation groove 4 is provided at the top of the base 3. The installation groove 4 is slidably matched with the mold body 1. By setting the mold body 1 in cooperation with the base 3, it is convenient for the operator to select different mold bodies 1 according to different mobile phone models, improving the adaptation range of the device.

[0027] On both sides of the base 3, there are fastening members 5 threadedly connected for tightly pressing the mold body 1. The fastening member 5 includes a fastening plate 501. One side of the fastening plate 501 abuts against the side wall of the mold body 1, and the other side of the fastening plate 501 is fixedly connected to a threaded rod 502. The threaded rod 502 is threadedly connected to the base 3. One end of the threaded rod 502 is fixedly installed with a turntable 503. The turntable 503 is arranged outside the base 3. By setting the turntable 503, the threaded rod 502 can be driven to rotate, so that the threaded rod 502 pushes the fastening plate 501 to tightly press the mold body 1, improving the stability of the mold body 1, thereby improving the dispensing accuracy. At the same time, when demolding, a clamping force can be provided for the mold body 1, facilitating the lifting plate 6 to push the bracket and the screen upward to disengage from the placement groove 2.

[0028] It also includes a demolding assembly. The demolding assembly includes a lifting plate 6. The lifting plate 6 has a sliding clearance fit with the middle of the bottom of the base 3 and the middle of the mold body 1. The two sides of the bottom of the lifting plate 6 are set as inclined surfaces. The inclined surfaces of the lifting plate 6 abut against the inclined surfaces of the pushing plates 7. The pushing plates 7 are slidably installed on both sides of the bottom of the base 3. Connecting plates 8 are installed at the bottom sides of both sides of the lifting plate 6. The middles of the two groups of pushing plates 7 are respectively in threaded fit with two groups of threaded grooves with opposite directions opened on the surface of the bidirectional lead screw 14. One end of the bidirectional lead screw 14 is rotatably fitted with the inner wall of one side of the base 3, and the other end of the bidirectional lead screw 14 is rotatably fitted with the inner wall of the other side of the base 3 and penetrates through the base 3 and is fixedly installed with a rotating handle 15 outside the base 3. By setting the rotating handle 15, the bidirectional lead screw 14 can be driven to rotate, so that the two groups of pushing plates 7 move towards each other simultaneously, making the lifting plate 6 abutting against the inclined surfaces of the pushing plates 7 move horizontally upward, applying a uniform thrust to the bottom of the bracket and the screen for demolding. At the same time, it can prevent the bracket and the screen from being damaged due to uneven force; the connecting plate 8 is slidably fitted with a sliding column 9. The sliding column 9 is fixedly installed in a movable groove 10 opened on the base 3. A spring 11 is slidably sleeved on the surface of the sliding column 9. The bottom of the spring 11 abuts against the top surface of the connecting plate 8, and the top of the spring 11 is fixedly connected to the inner wall of the movable groove 10. By setting the spring 11, it can be compressed when the connecting plate 8 moves upward, thereby providing a downward force for the connecting plate 8. When the pushing plates 7 move outward, the spring 11 pushes the connecting plate 8 to drive the lifting plate 6 to move downward, moving the lifting plate 6 to the initial position, thus facilitating the next dispensing; sliders 12 are fixedly installed on both sides of the pushing plates 7, and sliding grooves 13 are opened on both sides of the inner wall of the base 3. The sliders 12 are slidably fitted with the sliding grooves 13. By setting the sliders 12 and the sliding grooves 13 to be used in cooperation, the stability of the pushing plates 7 can be improved.

[0029] During specific use, move this device to the designated position, select the corresponding mold body 1 according to the mobile phone model, place the mold body 1 in the installation groove 4, rotate the turntables 503 of the two sets of fastening members 5 in the forward direction, so that the turntables 503 drive the threaded rods 502 to rotate. The threaded rods 502 that are in threaded cooperation with the base 3 move towards the inside of the base 3. The threaded rods 502 push the fastening plates 501 to fasten both sides of the mold body 1, thereby fastening and fixing the mold body 1 in the installation groove 4. Place the bracket in the placement groove 2 of the mold body 1, and then use an external dispensing device to dispense glue along the peripheral wall of the placement groove 2 around the top surface of the bracket. Then place the screen in the placement groove 2 so that the screen is adhesively fixed to the bracket. After the glue hardens, rotate the rotating handle 15. The rotating handle 15 drives the bidirectional lead screw 14 to rotate, and the two sets of push plates 7 that are threadedly connected in the two sets of reverse threaded grooves start to move towards each other, so that the lifting plate 6 that abuts against the inclined surfaces of the push plates 7 moves horizontally upward, applying a uniform thrust to the bottom of the bracket and the screen, and pushing the bracket and the screen out of the placement groove 2, thereby realizing mold removal.

[0030] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
