The injection molding machine includes a melting system, a transmission system, a mold, etc. The transmission system includes a feeding pipe. The transmission system moves the melted raw materials into the mold through the feeding pipe, so that the melted raw materials solidify and become a plastic product of a specified shape.

[0003] For example, the utility model with patent number CN219133103U discloses an injection mold for processing a rubber frame, including a fixed mold and a movable mold matched with the fixed mold, and also includes a material reduction component, a nozzle for feeding glue, and an injection flow channel connected to the nozzle glue outlet; the material reduction component includes a material reduction plate and a fixed plate arranged above the material reduction plate, the material reduction plate is arranged in the A plate and located above the front mold core, and the fixed plate is arranged in the push plate; the injection flow channel is arranged in the front mold core and its outlet is connected to the cavity. When the existing injection molding machine is working, it needs to wait for a complete process to be completed before the transmission system will transfer the melted raw materials to the mold to manufacture the next group of plastic products. The transmission system of the injection molding machine will be in a stopped state for a period of time, resulting in low injection efficiency. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide an injection mold for the production of computer plastic frames to solve the technical problem that when the injection molding machine is working, it needs to wait for a complete process to be completed before the next group of plastic products can be manufactured, resulting in low injection molding efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an injection mold for producing computer plastic frames, comprising a feeding tube, a rotatable connecting sleeve is provided on the feeding tube, a second connecting column and a movable column are provided on the connecting sleeve, and a manufacturing mechanism for manufacturing plastic products is provided on the movable column; a fixed plate is provided on the injection molding machine, a first sliding frame, two groups of second sliding frames and a third sliding frame are provided on the fixed plate, the first sliding frame and the third sliding frame are both in an arc shape, the second sliding frame is inclined and are not located in the same horizontal plane, the two ends of the two groups of the second sliding frames are respectively connected to the two ends of the first sliding frame and the two ends of the third sliding frame, the first sliding frame, the two groups of the second sliding frames and the third sliding frame form a closed figure; the manufacturing mechanism comprises a fixed plate, a matching block is provided on the fixed plate, and the matching block is slidably mounted in the first sliding frame / the second sliding frame / the third sliding frame. When in use, the manufacturing mechanism is driven to move by the rotating mechanism. When the matching block is located in the first sliding frame, the corresponding manufacturing mechanism performs injection molding, solidification and cooling steps. When the matching block moves to the second sliding frame, the plastic product production is completed. When the matching block moves to the third sliding frame, the corresponding manufacturing mechanism demoulds the plastic product, and the staff takes the plastic product out of the injection molding machine and collects the plastic product. Several groups of mold bodies cooperate to ensure that the melted raw materials in the injection molding machine are continuously injected into the mold body, thereby improving the efficiency of injection molding.

[0006] Furthermore, the manufacturing mechanism includes a mold body, the mold body includes a fixed mold and a movable mold, the fixed mold is provided with a connecting pipe, the other end of the connecting pipe is connected to the connecting sleeve, the movable column is provided with a fixing frame, the fixing frame is fixedly connected to the fixed mold, the fixing plate is slidably connected to the movable column, and the fixing plate is fixedly connected to the movable mold. The matching block on the manufacturing mechanism cooperates with the first sliding frame / the second sliding frame / the third sliding frame, and is driven by the rotating mechanism, so that the manufacturing mechanism completes the specified process at the specified position, thereby ensuring that several groups of mold bodies can operate normally, and multiple groups of injection molded products are manufactured at the same time, thereby improving the efficiency of injection molding.

[0007] Furthermore, the matching block is hexagonal, and the inclination angle of the matching block is the same as the inclination angle of the second sliding frame, ensuring that the matching block always has two faces in contact with the first sliding frame / the second sliding frame / the third sliding frame. Through the shape of the matching block, the matching block can perfectly transition at the connection between the first sliding frame and the second sliding frame or the second sliding frame and the third sliding frame, so that the manufacturing mechanism can operate smoothly.

[0008] Furthermore, a limit block is provided on the movable column, and a limit slot is provided on the fixed plate, and the limit block is slidably mounted in the limit slot. The limit block cooperates with the limit slot so that the fixed plate can only slide up and down on the movable column, and cooperates with the matching block so that the manufacturing mechanism can move along a specified route, thereby ensuring the efficiency of injection molding.

[0009] Furthermore, a driving mechanism for driving the rotating mechanism is provided below the fixed frame, and the driving mechanism includes a driving motor, and the output shaft of the driving motor is connected to a worm, and the worm is meshed with a worm wheel, and the worm wheel is fixedly connected to a first connecting column, and the first connecting column is fixedly connected to the movable column. The driving mechanism is used to drive the movable column to rotate, so that the manufacturing mechanism can manufacture plastic products, and the driving mechanism keeps the movable column rotating at a constant speed. By adjusting the rotation speed of the driving mechanism and the number of manufacturing mechanisms, it is ensured that the melted raw materials can be continuously poured into a plurality of groups of mold bodies in sequence, thereby improving the efficiency of injection molding.

[0010] Furthermore, the fixed frame is provided with a support frame, the first connecting column is installed on the support frame, the support frame is provided with two groups of support seats, and the two ends of the worm are installed on the two groups of support seats respectively. The support frame and the support seat are used to support the movable column and the worm.

[0011] The working principle and beneficial effects of this solution are:

[0012] When in use, the driving mechanism drives the movable mold, the fixed mold and the fixed plate to rotate, and the fixed plate drives the matching block to move in the third sliding frame. At this time, the fixed mold is separated from the movable mold and moves from the third sliding frame to one of the second sliding frames, driving the corresponding fixed plate and the movable mold to rise, reducing the distance between the movable mold and the fixed mold. When the matching block moves to the first sliding frame, the movable mold and the fixed mold are fitted, and the melted raw material flows into the mold body through the connecting pipe. The mold body is filled with raw materials and stops. When the matching block slides in the first sliding frame, the mold body goes through the stages of injection, solidification and cooling. When cooling is completed, the matching block is located at the connection between the first sliding frame and the second sliding frame. The matching block slides in the second sliding frame, driving the movable mold and the plastic product to move downward. When the matching block moves to the third sliding frame, the plastic product is demolded by the demolding device in the movable mold, and the staff can remove the plastic product.

[0013] When several groups of manufacturing mechanisms are in use, several groups of mold bodies are located at different stages respectively. By controlling the number of mold bodies and the rotation speed of the rotating mechanism, it is ensured that there is always only one group of connecting tubes to transport the melted raw materials to the corresponding mold bodies. When one group of mold bodies is filled with raw materials, the connection between the current connecting tube and the corresponding mold body is disconnected, and at the same time, another group of connecting tubes is connected to another group of mold bodies to inject the melted raw materials into the corresponding mold bodies, ensuring that there is always melted raw materials poured into the mold bodies, thereby improving the efficiency of injection molding.

[0024] When implementing

[0025] When in use, the injection molding machine is started, and the melted raw material moves through the feeding tube 1 to several groups of connecting tubes 3, and then moves from the connecting tubes 3 to the corresponding mold body 6. When the movable mold 5 is fitted with the fixed mold 4, the melted raw material will enter the mold body 6 from the connecting tube 3. When the movable mold 5 is not fitted with the fixed mold 4, the melted raw material will not flow out of the connecting tube 3; the mold body 6 cooperates with the driving mechanism and the manufacturing mechanism to move several groups of mold bodies 6; the matching block 12 located in the third sliding frame 10 first moves to the connection between the third sliding frame 10 and one group of the second sliding frames 9. At this time, one group of inclined surfaces of the matching block 12 is fitted with one side of the second sliding frame 9, and the second sliding frame 9 cooperates with the matching block 12 to drive the corresponding fixed plate 11 to rise, and drive the movable mold 5 to rise. When the fixed plate 11 rises, the limit block 23 slides in the limit groove 24. When the matching When the matching block 12 moves to the connection between the first sliding frame 8 and the second sliding frame 9, the movable mold 5 is tightly fitted with the fixed mold 4. At this time, the connecting pipe 3 is connected to the mold body 6, and the melted raw material flows into the mold body 6 until the mold body 6 is filled with the raw material and stops. At the same time, the mold body 6 rotates around the movable column 14, and the matching block 12 slides in the first sliding frame 8. The plastic product goes through the solidification and cooling stages. When the cooling is completed, the matching block 12 moves to the connection between the first sliding frame 8 and the second sliding frame 9. An inclined surface of the matching block 12 contacts the second sliding frame 9, and the second sliding frame 9 cooperates with the matching block 12 to drive the movable mold 5 to move downward. At this time, the plastic product is located in the movable mold 5, so that the matching block 12 moves to the third sliding frame 10. At this time, the plastic product is separated from the movable mold 5 through the demolding device in the movable mold 5, and the staff picks the plastic product out of the movable mold 5.

[0026] When the driving mechanism drives the rotating mechanism to move, the driving motor 15 is started, and the driving motor 15 drives the worm 16 to rotate through the connector, and the worm 16 rotates on the two sets of support seats 21, and the worm 16 drives the worm wheel 17 to rotate, and the worm wheel 17 drives the first connecting rod 18 and the movable column 14 to rotate, and the first connecting rod 18 rotates in the support frame 19, and the movable column 14 drives several sets of fixed plates 11 and fixed frames 13 to rotate, and the fixed frame 13 and the fixed plate 11 respectively drive the fixed mold 4 and the movable mold 5 to rotate around the movable column 14, and the matching block 12 on the movable mold 5 slides in the first sliding frame 8 / the second sliding frame 9 / the third sliding frame 10. Since the first sliding frame 8, the second sliding frame 9 and the third sliding frame 10 form a closed figure and are circular when viewed from above, it is ensured that the matching block 12 is always located in the first sliding frame 8 / the second sliding frame 9 / the third sliding frame 10. The driving mechanism always drives the movable column 14 to rotate at a constant speed, thereby improving the automation of the machine.

[0027] When several groups of mold bodies 6 are in use, they are respectively located at different stages, and only one group of movable molds 5 is always separated from the fixed mold 4. At the same time, only one group of connecting pipes 3 transports the melted raw materials to the mold bodies 6. By controlling the number of mold bodies 6 and the rotation speed of the rotating mechanism, it is ensured that after the previous group of mold bodies 6 is filled with raw materials, another group of connecting pipes 3 is connected with another group of mold bodies 6 to pour the other group of mold bodies 6, ensuring that the transmission system is always in operation and that melted raw materials are always poured into the mold bodies 6, thereby improving the efficiency of injection molding; the stages of plastic products in several groups of mold bodies 6 are staggered, and time is used reasonably, thereby ensuring that more plastic products can be manufactured in the same time, thereby improving the efficiency of injection molding.

It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the utility model.
