Description

Technical Field

[0001] This utility model relates to the field of keyboard mold technology, specifically a keyboard mold that is easy to demold. Background Technology

[0002] A keyboard is a common computer input device that can input information such as numbers and text into the computer, operate various computer commands, and control games. The keyboard is an important tool for interaction between the computer and the computer user, enabling people to efficiently and accurately input information into the computer to complete various tasks. Keyboards are divided into mechanical keyboards, membrane keyboards, wireless keyboards, etc. Keyboard molds are one of the key tools for manufacturing keyboard shells, bringing convenience and speed to the manufacturing of complex keyboard shells, and enabling the mass production of irregular keyboard shells.

[0003] During the manufacturing process of keyboard casings, materials are injected into molds and cooled while waiting for the molds to solidify. Finally, the molds are opened to remove the cooled and manufactured keyboard casings. However, during the removal of the keyboard casings, some inevitably stick to the upper or lower molds as the molds are opened. These stuck keyboard casings are difficult to remove and are prone to deformation and damage after removal. Utility Model Content

[0004] The purpose of this invention is to provide a keyboard mold that is easy to demold, in order to solve the problem mentioned in the background art that the keyboard is easy to stick to the inside of the mold and is difficult to remove and is easily damaged during demolding.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a keyboard mold that is easy to demold, comprising a frame, a hydraulic cylinder fixedly installed on the outer surface of the frame, the hydraulic cylinder being located at the center of the frame, a lower mold fixedly installed on the outer surface of the frame, an upper mold inserted into the outer surface of the lower mold, and the upper mold being connected to the output end of the hydraulic cylinder.

[0006] Preferably, an elastic pushing mechanism is provided between the upper mold and the lower mold. The elastic pushing mechanism includes a threaded slider, which is slidably installed inside the lower mold and engaged with it. A second spring is provided between the threaded slider and the lower mold. An ejector rod is fixedly installed on the outer surface of one end of the threaded slider, and the outer surface of the ejector rod penetrates the outer surface of the lower mold. The lower mold and the ejector rod are slidably connected, and the ejector rod is located on the outer surface of the lower mold.

[0007] By adopting the above technical solution, when the upper mold separates from the lower mold, the threaded slider will be pushed by the second spring, causing the threaded slider to pop up with the ejector rod, so that the ejector rod pushes the injection-molded keyboard shell out of the lower mold, so that the keyboard shell will not get stuck inside the lower mold, reducing the chance of deformation and damage when the keyboard shell is removed.

[0008] Preferably, a guide rod is fixedly installed on the outer surface of the upper mold near the hydraulic cylinder, and the guide rod is located at the four corners of the upper mold. A sleeve is fixedly installed on the outer surface of the frame, and the outer surface of the sleeve is penetrated by the guide rod, and the guide rod and the sleeve are slidably connected.

[0009] By adopting the above technical solution, the guide rod can provide stability for the movement of the upper mold, enabling the upper mold to move vertically along the direction of the guide rod, reducing the distance error generated when the upper and lower molds open and close, reducing the probability of jamming between the upper and lower molds, and at the same time, the wear of the guide rod can be reduced by the sleeve, and it can be replaced in time when the upper mold moves and displacement occurs, eliminating the shaking generated when the upper mold moves.

[0010] Preferably, a contact ejection mechanism is provided between the upper mold and the frame, which allows the keyboard that is adhered to the upper mold to be ejected, reducing the difficulty of removing the keyboard when it is adhered.

[0011] By adopting the above technical solution, the difficulty of removing the keyboard shell from the upper mold can be reduced, and the material unloading speed can be increased.

[0012] Preferably, the contact ejection mechanism includes: an ejector rod, which is slidably installed inside the upper mold and engaged with the upper mold; a first spring is provided between the ejector rod and the upper mold; one end of the ejector rod is located outside the upper mold; and one end of the ejector rod is in contact with the outer surface of the frame.

[0013] Using the above technical solution, when the keyboard shell is adhered to the upper mold, the retraction of the hydraulic cylinder will cause the push rod to contact the frame, allowing the push rod to move as it contacts the frame and push out the keyboard shell stuck in the upper mold. This makes it easy to push the adhered keyboard shell out without prying it off, reducing the difficulty of removing the keyboard shell and the chance of damage when removing it.

[0014] Preferably, the lower mold has a uniform threaded mounting of a positioning screw sleeve on its outer surface, and the positioning screw sleeves are located at the four corners of the lower mold. The outer surface of the positioning screw sleeve has an installation hole, and the installation hole is located outside the lower mold. The positioning screw sleeve is inserted into the upper mold, and the upper mold is engaged with the positioning screw sleeve.

[0015] By adopting the above technical solution, the upper and lower molds can be positioned by the positioning screw sleeve, so that the upper and lower molds can be automatically and finely adjusted when they are closed. After the positioning screw sleeve is worn, it can be replaced by inserting a tool into the mounting hole and using force to unscrew the screw sleeve.

[0016] Preferably, the outer surface of the threaded slider is threaded with a threaded sleeve, and the outer surface of the threaded sleeve is provided with an installation hole. The threaded slider and the threaded sleeve are concentrically designed, and the threaded sleeve fits against the outer surface of the lower mold. Positioning blocks are fixedly installed on the outer surfaces of both ends of the threaded slider, and the positioning blocks engage with the lower mold. The lower mold and the positioning blocks are slidably connected.

[0017] Using the above technical solution, the threaded sleeve can be replaced through the mounting hole, and the positioning block makes the threaded slider more stable and convenient when replacing the threaded sleeve, so that the threaded sleeve can act as a push pin.

[0018] Preferably, the lower mold is provided with mounting feet around its perimeter, and the outer surface of the mounting feet is provided with an oblong hole, and a bolt is threaded between the oblong hole of the mounting foot and the frame.

[0019] Using the above technical solution, the position of the lower mold can be finely adjusted through the oblong holes on the outer surface of the mounting feet.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the keyboard mold that facilitates demolding:

[0021] 1. When the mold is opened, the upper mold and the lower mold will separate. As the upper mold and the lower mold separate, the threaded slider will be pushed out by the second spring, so that the ejector rod can slide and move out of the lower mold, so that the keyboard shell in the lower mold can be ejected, so that the keyboard shell will not be deformed or damaged during the removal process, reducing the difficulty of removing the keyboard shell and increasing the production speed.

[0022] 2. When the hydraulic cylinder retracts, it will drive the upper mold to move along the direction of the guide rod, so that the ejector rod can contact the outer surface of the frame. This allows the ejector rod to slide inside the frame and push the keyboard shell out of the upper mold through the ejector rod, preventing the keyboard shell from getting stuck inside the upper mold. This reduces the chance of the keyboard shell getting stuck in the upper mold during manufacturing and improves production efficiency.

[0023] 3. The threaded sleeve and locating sleeve provide fine positioning for the closing of the upper and lower molds, making the molds more accurate during closing. After long-term use, when the threaded sleeve and locating sleeve wear out, they can be removed through the mounting holes for easy replacement. This ensures that the upper and lower molds maintain accurate mold closing and reduces the chance of jamming during mold closing and opening. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6This utility model provides a technical solution: a keyboard mold that is easy to demold, including a frame 1, a hydraulic cylinder 2 fixedly installed on the outer surface of the frame 1, and the hydraulic cylinder 2 is located at the center of the frame 1. A lower mold 4 is fixedly installed on the outer surface of the frame 1, and an upper mold 3 is inserted and installed on the outer surface of the lower mold 4. The upper mold 3 is connected to the output end of the hydraulic cylinder 2. An elastic pushing mechanism is provided between the upper mold 3 and the lower mold 4. The elastic pushing mechanism includes a threaded slider 9, which is slidably installed inside the lower mold 4 and is engaged with the lower mold 4. A second spring 12 is provided between the threaded slider 9 and the lower mold 4. An ejector rod 11 is fixedly installed on the outer surface of one end of the threaded slider 9, and the outer surface of the ejector rod 11 penetrates the outer surface of the lower mold 4. The lower mold 4 and the ejector rod 11 are slidably connected, and the ejector rod 11 is located on the outer surface of the lower mold 4.

[0033] After injection molding is completed, the hydraulic cylinder 2 will drive the upper mold 3 to move, so that the upper mold 3 and the lower mold 4 are separated. The second spring 12 can push out the threaded slider 9, so that the ejector rod 11 can move along with it and extend out of the lower mold 4. The keyboard shell stuck in the lower mold 4 can be pushed out by the ejector rod 11, so that the keyboard shell will not be stuck inside the lower mold 4, reducing the difficulty of removing the keyboard shell from the lower mold 4, reducing the chance of damage and deformation when removing the keyboard shell, and improving the production efficiency of the keyboard shell.

[0034] A guide rod 5 is fixedly installed on the outer surface of the upper mold 3 near the hydraulic cylinder 2, and the guide rod 5 is located at the four corners of the upper mold 3. A sleeve 6 is fixedly installed on the outer surface of the frame 1, and the outer surface of the sleeve 6 is penetrated by the guide rod 5, and the guide rod 5 and the sleeve 6 are slidably connected.

[0035] The guide rod 5 allows the upper mold 3 to move vertically and stably along the direction of the guide rod 5 when moving within the frame 1. This makes the upper mold 3 and lower mold 4 more stable when closing and opening, reducing the chance of jamming when they are opening and closing. At the same time, the sleeve 6 can also protect the frame 1, preventing the guide rod 5 from needing to be replaced due to wear on the frame 1, thus reducing the cost of use. It also ensures that the upper mold 3 will not shake during movement, which could cause the upper mold 3 and lower mold 4 to jam when opening and closing.

[0036] A contact ejection mechanism is provided between the upper mold 3 and the frame 1. The keyboard that is adhered to the upper mold 3 can be ejected by the contact ejection mechanism, reducing the difficulty of removing the keyboard when it is adhered. The contact ejection mechanism includes: an ejector rod 7, which is slidably installed inside the upper mold 3 and the upper mold 3 is engaged with the ejector rod 7. A first spring 8 is provided between the ejector rod 7 and the upper mold 3. One end of the ejector rod 7 is located outside the upper mold 3 and the other end of the ejector rod 7 is in contact with the outer surface of the frame 1.

[0037] After injection molding is completed, hydraulic cylinder 2 will drive upper mold 3 to move, so that upper mold 3 can move along the direction of guide rod 5, so that ejector rod 7 contacts the outer surface of frame 1, so that keyboard shell inside upper mold 3 can be ejected, reducing the deformation and damage caused by removing keyboard shell from upper mold 3. After upper mold 3 and lower mold 4 are closed, first spring 8 will push ejector rod 7 to automatically reset.

[0038] The lower mold 4 has a uniform threaded mounting of a positioning screw sleeve 14 on its outer surface, and the positioning screw sleeve 14 is located at the four corners of the lower mold 4. The outer surface of the positioning screw sleeve 14 has a mounting hole 15, and the mounting hole 15 is located outside the lower mold 4. The positioning screw sleeve 14 is inserted into the upper mold 3, and the upper mold 3 is engaged with the positioning screw sleeve 14.

[0039] The upper mold 3 can be positioned by the positioning screw sleeves 14 at the four corners of the lower mold 4, so that the upper mold 3 and the lower mold 4 can be accurately closed, making it easier to close the upper mold 3 and the lower mold 4.

[0040] The threaded slider 9 has a threaded sleeve 13 threaded on its outer surface, and the threaded sleeve 13 has a mounting hole 15 on its outer surface. The threaded slider 9 and the threaded sleeve 13 are concentrically designed, and the threaded sleeve 13 fits against the outer surface of the lower mold 4. Positioning blocks 10 are fixedly installed on the outer surfaces of both ends of the threaded slider 9, and the positioning blocks 10 are engaged with the lower mold 4. The lower mold 4 and the positioning blocks 10 are slidably connected.

[0041] The threaded sleeve 13 allows the threaded slider 9 and ejector rod 11 to retract into the lower mold 4 after the upper mold 3 and lower mold 4 are closed. After long-term use, the threaded sleeve 13 and the positioning screw sleeve 14 will inevitably wear. At this time, the threaded sleeve 13 and the positioning screw sleeve 14 can be removed from the lower mold 4 by inserting a tool into the mounting hole 15. The positioning block 10 can enhance the strength of the threaded sleeve 13.

[0042] The lower mold 4 is provided with mounting feet 16 around its perimeter, and the outer surface of the mounting feet 16 is provided with a waist-shaped hole. Bolts are threaded between the waist-shaped hole of the mounting feet 16 and the frame 1.

[0043] The position of the lower mold 4 can be finely adjusted through the oblong holes of the mounting feet 16, making it convenient to adjust the position of the lower mold 4 on the frame 1.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
