Implementation

The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

Example

As shown in Figures 1 to 5, a multi-station injection mold comprises an injection mold bottom plate 1 and an injection mold top plate 2, a processing groove 3, a pressure plate 4, a glue injection box 5 and a guide tube 6. The injection mold top plate 2 is fixed on the upper surface of the injection mold bottom plate 1 and is symmetrically arranged. The upper surface of the injection mold bottom plate 1 is provided with at least four symmetrically arranged processing grooves 3, and the bottom surface of the injection mold top plate 2 is provided with a pressure plate 4 corresponding to the processing grooves 3. A glue injection box 5 is provided above the injection mold top plate 2, and the guide tube 6 is fixed below the glue injection box 5 and is connected. Mounting plates 7 are symmetrically arranged on both sides of the upper surface of the injection mold top plate 2, and the upper surface of the mounting plate 7 is fixedly connected to a support plate 8. The two support plates 8 are A threaded rod 9 is rotatably connected to the surface, a driving motor 10 is fixedly connected to the surface of a support plate 8 on one side, one end of the threaded rod 9 passes through the surface of the support plate 8 and is fixedly connected to the output shaft of the threaded rod 9, a connecting block 11 threadedly connected to the threaded rod 9 is fixed to the upper surface of the injection box 5, two symmetrically distributed guide rods 12 are fixed between the facing surfaces of the two support plates 8, the guide rods 12 are located on both sides below the threaded rod 9, and the guide rods 12 and the threaded rods 9 are distributed in a triangular shape, the contact surface between the guide rods 12 and the connecting block 11 is smooth and fitting, a receiving plate 13 connected to the pressure plate 4 is fixed to the upper surface of the injection molding top plate 2, and the receiving plate 13 is in the shape of a cone with a larger top and a smaller bottom.

The working principle of the above technical solution is as follows:

When it is necessary to perform glue injection processing and molding for multiple products, the drive motor 10 can be started and adjusted according to the amount of glue required to be injected. The drive motor 10 can then drive the threaded rod 9 to rotate when started, so that the threaded rod 9 can threadably drive the connecting block 11 to drive the glue injection box 5 to move. The guide rod 12 is set so that when the connecting block 11 and the threaded rod 9 move, the guide rod 12 is limited to prevent the connecting block 11 from flipping over when the threaded drive of the threaded rod 9 is applied. The glue injection box 5 can then be driven by the connecting block 11 to deliver the injection material through the outlet pipe 6. The receiving plate 13 set at this time can improve the feeding effect of the glue injection and prevent it from spilling, thereby achieving the effect of facilitating multiple workstations and preventing the injection mold base plate 1 from being processed individually when processing the product, thereby affecting work efficiency.

In another embodiment, as shown in Figures 2, 4 and 5, an operating groove 14 is opened in the injection mold base plate 1 and is located below the processing groove 3. At least three symmetrically arranged driving cylinders 15 are fixed to the bottom surface of the inner wall of the operating groove 14. A push plate 16 located below the processing groove 3 is fixed to the output end of the driving cylinder 15. A plurality of evenly distributed push rods 17 are fixed to the upper surface of the push plate 16. The top end of the push rod 17 passes through the processing groove 3. A push sleeve 18 is fixed to the top end of the push rod 17. The bottom end of the push sleeve 18 is in contact with the bottom surface of the inner wall of the processing groove 3.

When it is necessary to demould the mold for injection molding in the processing groove 3, the three driving cylinders 15 can be started first to synchronously push the push plate 16 upward, and then the push plate 16 can cause the push rod 17 to be pushed when moving upward, thereby driving the push sleeve 18 to move upward, so that the push sleeve 18 can evenly push the molded product upward, so that the product can be gradually moved out of the processing groove 3 by the pushing force, achieving the effect of facilitating demoulding and preventing the injection mold base plate 1 from being inconvenient to demould after the product processing is completed, resulting in poor overall work efficiency.

The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
