Description

Technical Field

[0001] This utility model relates to the field of injection mold demolding technology, specifically to an injection mold for mouse shells that allows for smooth demolding. Background Technology

[0002] A mouse is a commonly used computer input device, available in wired and wireless versions. It allows for cursor positioning on the screen and control of the screen via buttons and a scroll wheel. The mouse casing is made of plastic, and most mouse casings on the market are manufactured using injection molding, a process that combines injection and molding.

[0003] Chinese Patent Publication No. CN218985615U discloses a mouse shell injection mold, belonging to the field of mold technology. It includes a fixed mold and a movable mold, with a demolding mechanism installed between them. The demolding mechanism includes a demolding platen, with movable shafts installed at four corners near the movable mold end, all four shafts penetrating the movable mold. A wedge-shaped stop is installed at the bottom of the demolding platen. Multiple punches are evenly spaced near the fixed mold end of the movable mold. A base is installed at the bottom of both the fixed and movable molds, with a material discharge groove at the top of the base. The stop is located inside the material discharge groove. This demolding mechanism enables quick and convenient demolding of the mouse shell without the need for ejector pins. It effectively solves the problems of traditional molds where the protrusions on the ejector pins easily bend or break during demolding, resulting in a short service life of the injection mold. Furthermore, the high friction between the ejector pins and the injection cavity leads to significant resistance and unsmooth demolding.

[0004] The aforementioned device removes the punch from the slot of the ejector platen. At this point, the mouse shell outside the punch loses its supporting force, thus completing the demolding process. However, when the mouse shell injection molded part is first formed, it is easy to stick to the punch. The overall structural stability of the mouse shell injection molded part is relatively low. If the mouse shell injection molded part is directly removed from the outside of the punch, it is easy to damage the injection molded part, thereby affecting the quality of the mold. Utility Model Content

[0005] To address the aforementioned issues, a mouse shell injection mold that enables smooth demolding is provided. An external gas supply device transports gas through a gas supply pipe to the interior of a first annular tube. The first annular tube then transports the gas to the interior of an inlet pipe and a second annular tube. Multiple nozzles inside the second annular tube then spray the gas, gradually loosening the molded mouse shell using the air pressure. A hydraulic rod is then activated, moving a ring-shaped movable plate downwards. Simultaneously, the support block and punch at the top of the ring-shaped movable plate also move downwards. The loosened mouse shell, working in conjunction with a placement plate, facilitates the demolding of the mouse shell, resulting in a smoother demolding process.

[0006] To address the problems of existing technologies, this utility model provides a mouse shell injection mold that enables smooth demolding, including a demolding cylinder, a cover plate movably disposed on the top of the demolding cylinder, an annular support plate disposed inside the demolding cylinder, a plurality of injection cylinders for injection on the top of the annular support plate, a placement tray disposed inside the injection cylinder, a support block movably disposed inside the placement tray, a punch for injection molding the mouse shell disposed on the top of the support block, and a blowing component for blowing the injection mold disposed on the top of the placement tray.

[0007] Preferably, the blowing assembly includes a second annular tube disposed on the top of the placement tray, the interior of the second annular tube being connected to a plurality of nozzles for blowing the injection mold, and the interior of the second annular tube also being provided with an air inlet pipe for air intake.

[0008] Preferably, the demolding cylinder has a first annular pipe connected to the air inlet pipe inside, and the first annular pipe is also connected to an air supply pipe inside. One end of the air supply pipe extends to the outside of the demolding cylinder and is connected to the air supply equipment.

[0009] Preferably, the top of the cover plate is provided with an injection tube, the inside of which is connected to multiple material conveying pipes, and one end of the material conveying pipe is connected to an injection mold that works in conjunction with the punch.

[0010] Preferably, the demolding cylinder has an annular movable plate inside, and the top of the annular movable plate has a pull rod that matches the number of injection cylinders. The top of the pull rod is connected to the bottom of the support block.

[0011] Preferably, the demolding cylinder is provided with symmetrical hydraulic rods inside, and the telescopic ends of the hydraulic rods are connected to the bottom of the annular movable plate.

[0012] The advantages of this utility model compared to the prior art are:

[0013] Gas is transported through an external gas supply device to the inside of the first annular pipe via a gas supply pipe. The first annular pipe then transports the gas to the inside of the inlet pipe and the second annular pipe. The gas is then sprayed out by multiple nozzles inside the second annular pipe. The air pressure sprayed from the nozzles gradually blows the injection-molded mouse shell, causing the mouse shell to loosen slowly. Then, the hydraulic rod is activated to move the annular movable plate downwards. At the same time, the support block and punch at the top of the annular movable plate also move downwards. With the mouse shell loosened outside the punch working in conjunction with the placement plate, the mouse shell is demolded. The demolding of the mouse shell is smoother.

[0023] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 8 As shown, this utility model provides:

[0025] A mouse shell injection mold capable of smooth demolding includes a demolding cylinder 1, a cover plate 4 movably disposed on the top of the demolding cylinder 1, an annular support plate 7 disposed inside the demolding cylinder 1, a plurality of injection cylinders 6 for injection on the top of the annular support plate 7, a placement tray 14 disposed inside the injection cylinder 6, a support block 18 movably disposed inside the placement tray 14, a punch 17 for injection molding the mouse shell disposed on the top of the support block 18, and a blowing component for blowing the injection mold 13 disposed on the top of the placement tray 14.

[0026] By placing the cover plate 4 on the top of the demolding cylinder 1, the injection mold 13 is fitted above the punch 17, and a certain injection space is reserved between the injection mold 13 and the punch 17 to facilitate the injection molding of the mouse shell mold. Then, by using the blowing component, the injection-molded mouse shell can be blown, making the mouse shell smoother during the later demolding process.

[0027] like Figure 6 As shown, the blowing assembly includes a second annular tube 15 disposed on the top of the placement plate 14. The interior of the second annular tube 15 is connected to a plurality of nozzles 16 for blowing the injection mold 13. An air inlet pipe 10 for air intake is also disposed inside the second annular tube 15.

[0028] Gas is ejected from multiple nozzles 16 inside the second annular tube 15. The air pressure ejected from the nozzles 16 can gradually blow the injection-molded mouse shell, causing the mouse shell to loosen slowly, making it easier to demold later.

[0029] like Figure 5 As shown, the demolding cylinder 1 has a first annular pipe 11 inside which is connected to the air inlet pipe 10. The first annular pipe 11 is also connected to an air supply pipe 5 inside. One end of the air supply pipe 5 extends to the outside of the demolding cylinder 1 and is connected to the air supply equipment.

[0030] Gas is transported through an external gas delivery device to the inside of the first annular pipe 11 via the gas delivery pipe 5, and then the gas is transported by the first annular pipe 11 to the inside of the inlet pipe 10 and the second annular pipe 15.

[0031] like Figure 3 As shown, an injection tube 3 is provided on the top of the cover plate 4. Multiple material conveying tubes 2 are connected inside the injection tube 3. One end of the material conveying tube 2 is connected to an injection mold 13 that works in conjunction with the punch 17.

[0032] By feeding the injection material into the injection tube 3, the injection material will flow along the material delivery tube 2 to the injection mold 13 and the punch 17, thereby completing the injection work. After the injection is completed, the cover plate 4 and the injection mold 13 are removed.

[0033] like Figure 5 and Figure 6 As shown, an annular movable plate 8 is movably arranged inside the demolding cylinder 1. The top of the annular movable plate 8 is provided with pull rods 12, which are the same number as the number of injection cylinders 6. The top of the pull rods 12 is connected to the bottom of the support block 18.

[0034] The mouse shell, which is loose on the outside of the punch 17, works in conjunction with the placement plate 14 to demold the mouse shell, making the demolding process smoother.

[0035] like Figure 5 As shown, the demolding cylinder 1 is equipped with symmetrical hydraulic rods 9 inside, and the telescopic ends of the hydraulic rods 9 are connected to the bottom of the annular movable plate 8.

[0036] By activating the hydraulic rod 9, the annular movable plate 8 is moved downwards, and at the same time, the support block 18 and the punch 17 at the top of the annular movable plate 8 also move downwards.

[0037] Working principle: When injection molding a mouse shell is required, firstly, cover plate 4 is placed on top of the demolding cylinder 1. At this time, injection mold 13 is fitted above punch 17, and a certain injection space is reserved between injection mold 13 and punch 17. Then, injection material is fed into the injection tube 3. This injection material will flow along the material delivery pipe 2 to the space between injection mold 13 and punch 17, thus completing the injection molding process. After injection molding is completed, cover plate 4 and injection mold 13 are removed, while the injection-molded mouse shell remains outside punch 17. Then, the external gas delivery device is activated to transport gas through gas delivery pipe 5 to the first annular pipe. Inside the first annular pipe 11, the gas is transported to the air inlet pipe 10 and the second annular pipe 15. Then, multiple nozzles 16 inside the second annular pipe 15 spray out the gas. The air pressure sprayed from the nozzles 16 can gradually blow the injection-molded mouse shell, causing the mouse shell to loosen slowly. Then, the hydraulic rod 9 is activated to drive the annular movable plate 8 to move downward. At the same time, the support block 18 and the punch 17 on the top of the annular movable plate 8 will also move downward. With the mouse shell loosened outside the punch 17 working in conjunction with the placement plate 14, the mouse shell is demolded. At the same time, the demolding of the mouse shell is smoother.
