Technical Field

[0001] The present application relates to the technical field of injection molding equipment, and in particular to a vacuum pumping mechanism of an injection molding equipment for processing a mouse shell. Background Art

[0002] A mouse is an input device for a computer, which usually consists of a top cover, a bottom cover, a left mouse button, a right mouse button, and a scroll wheel button. According to ergonomics, the mouse shell is designed to be streamlined to improve the user's comfort. When producing the mouse shell, the injection mold is placed on the injection molding machine. For example, the Chinese utility model patent is named a mouse shell injection mold (application number CN202223322036.0), which includes a fixed mold and a movable mold. A mold ejection mechanism is installed between the fixed mold and the movable mold. The mold ejection mechanism includes a mold ejection plate. The mold ejection plate is equipped with movable shafts at the four corners of one end of the movable mold. The four movable shafts pass through the movable mold. A stopper with a wedge structure is installed at the bottom, and a plurality of punches are arranged at equal distances on the movable mold near one end of the fixed mold, and a plurality of slots for the punches to pass through are arranged at equal distances on the withdrawing mold plate. A concave mold groove that is compatible with the withdrawing mold plate, the stopper and the plurality of punches is provided on one side of the fixed mold near the movable mold. A base seat is installed at the bottom of the fixed mold and the movable mold, and a feed trough is provided on the top of the base seat, and the stopper is located inside the feed trough. The defect of the above-mentioned prior art is that the raw material is injected into the injection mold through the injection port of the injection molding machine, but because the plastic mold is in contact with the outside world and the mouse shell is streamlined, bubbles will appear on the product when the mouse shell is molded, thereby reducing the qualified rate of the mouse shell. Utility Model Content

[0003] The purpose of the utility model is to provide a vacuum pumping mechanism for an injection molding device used for processing a mouse shell in view of the defects and shortcomings of the prior art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] It includes a fixed template and a movable template, an isolation component is arranged between the fixed template and the movable template, the isolation component includes an isolation ring and a corrugated ring, one end of the isolation ring is arranged on one side of the fixed template, and one end of the corrugated ring is arranged at the end of the isolation ring away from the fixed template, and a vacuum pump is arranged on the outside of the isolation ring.

[0006] Preferably, the outer end of the isolation ring is provided with a storage ring groove for the corrugated ring to be inserted and placed.

[0007] Preferably, four guide rods are evenly arranged on the circumference of the outer circumference of the outer end of the corrugated ring, and a guide ring for the guide rods to be slidably inserted is arranged on the circumference of the outer circumference of the isolation ring.

[0008] Preferably, a compression spring is provided on the circumference of the guide rod, and the compression spring drives the corrugated ring and the isolation ring to move away from each other.

[0009] Preferably, a limiting nut is provided at one end of the guide rod close to the fixed template.

[0010] Preferably, a first magnetic ring is provided at the outer end of the corrugated ring, and a second magnetic ring is provided on one side of the movable template, and the first magnetic ring and the second magnetic ring attract each other.

[0011] Preferably, a placement ring groove for placing the second magnetic ring is opened on one side of the movable template, and the placement ring groove can allow the outer end of the corrugated ring to be inserted.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] 1. After the movable template approaches the fixed template, since there is a cavity between the fixed template and the movable template, injection molding is then performed in the cavity. In the process of the movable template approaching the fixed template, one side of the movable template abuts against one end of the corrugated ring, thereby compressing the corrugated ring. The corrugated ring is tightened in the storage ring groove, so that the isolation component separates the space between the fixed template and the movable template from the outside world. Then, the vacuum pump is started to extract the air in the isolation component, so that the air in the cavity is extracted. As a result, no bubbles appear on the surface of the produced mouse shell, thereby improving the qualified rate of the produced mouse shell;

[0014] 2. When the moving template contracts the corrugated ring, the compression spring is compressed at the same time. Then, during the injection molding process, the compression spring pushes the corrugated ring so that one end of the corrugated ring always contacts the side wall of the moving template, thereby improving the sealing between the isolation component and the moving template.

[0015] 3. When the movable template and the corrugated ring approach each other, the first magnetic ring and the second magnetic ring attract each other, so that one end of the corrugated ring is fixed to one side of the movable template. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] The embodiment of the present application discloses a vacuum pumping mechanism of an injection molding device for processing a mouse shell.

[0021] Reference Figure 1 and Figure 2 , including a base 1, a fixed template 2, a movable template 3 and an isolation component 4. The lower side of the fixed template 2 is fixed to the base 1 by bolts, the movable template 3 slides horizontally on one side of the fixed template 2, and the isolation component 4 is located between the fixed template 2 and the movable template 3.

[0022] The isolation assembly 4 includes an isolation ring 5 and a bellows ring 6. One end of the isolation ring 5 is mounted and fixed to one side of the fixed template 2. The isolation ring 5 has a storage ring groove 7 at the end away from the fixed template 2. One end of the bellows ring 6 is mounted and fixed to the bottom of the storage ring groove 7, and the other end of the bellows ring 6 protrudes out of the storage ring groove 7. A ring piece 8 is fixed to the outer end of the bellows ring 6. A vacuum pump 9 is fixed to the outside of the isolation ring 5 by bolts, and the suction pipe of the vacuum pump 9 passes through the side wall of the isolation ring 5. There is a cavity between the fixed template 2 and the movable template 3. When the injection molding machine is injecting into the cavity, as the movable template 3 approaches the fixed template 2, one side of the movable template 3 abuts against one end of the bellows ring 6, thereby compressing the bellows ring 6. The bellows ring 6 is tightened in the storage ring groove 7, so that the isolation assembly 4 separates the space between the fixed template 2 and the movable template 3 from the outside world. The vacuum pump 9 is then started to extract the air in the isolation assembly 4, thereby extracting the air in the cavity.

[0023] Four guide rods 10 are evenly fixed around the circumference of the ring segment 8 on the side close to the corrugated ring 6. Four guide rings 11 are evenly welded and fixed around the outer circumference of the outer end of the isolation ring 5. One end of the guide rod 10 is inserted and slidably inserted into the guide ring 11. The outer end of the guide rod 10 is threadedly connected to a limit nut 12, one side of which abuts the side of the guide ring 11 away from the ring segment 8. Under the action of the limit nut 12, the extension length of the corrugated ring 6 can be limited.

[0024] A compression spring 13 is sheathed around the guide rod 10. One end of the compression spring 13 abuts the side wall of the ring piece 8, and the other end of the compression spring 13 abuts the side wall of the guide ring 11. When the movable platen 3 contracts the corrugated ring 6, the compression spring 13 is simultaneously compressed. Subsequently, during the injection molding process, the corrugated ring 6 is pushed by the compression spring 13, so that one end of the corrugated ring 6 always abuts the side wall of the movable platen 3.

[0025] A first magnetic ring 14 is fixedly attached to the outer side of the ring plate 8. A placement ring groove 16 is circumferentially formed on the side of the movable plate 3 near the fixed plate 2. A second magnetic ring 15 is fixedly attached to the bottom of the placement ring groove 16. The placement ring groove 16 allows one end of the corrugated ring 6 to be inserted. When the movable plate 3 and the corrugated ring 6 approach each other, the first magnetic ring 14 and the second magnetic ring 15 attract each other, allowing one end of the corrugated ring 6 to be fixed to the side of the movable plate 3.

[0026] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
