[0001] The utility model relates to the technical field of automobile parts production equipment, in particular to a handle injection molding device for manufacturing automobile combination switches. Background Art

[0002] The combination switch handle of a car is a device used to control multiple functions of the vehicle. Usually, the combination switch handle of a car contains multiple function buttons and switches, which can be used to control multiple functions such as lights, wipers, turn signals, etc. These handles are usually installed near the steering wheel or on the vehicle dashboard, making it easy for the driver to operate various functions of the vehicle. The design and function of the combination switch handle will vary depending on the model and manufacturer;

[0003] Automotive combination switch handles are typically manufactured by injection molding, a common manufacturing process used to produce a variety of plastic parts, including automotive parts. When manufacturing automotive combination switch handles, injection molding ensures consistent, high-quality, and durable parts.

In addition, the injection molded parts lack targeted cooling facilities after the injection molding is completed. After taking out the materials, the injection molded parts are directly placed on the conveyor and cooled during the conveying process. However, the cooling effect is slow, resulting in deformation of the injection molded parts during the conveying to the processing process.

[0033] Embodiment 2

[0034] like Figure 1 and Figure 5 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0035] In this embodiment, the support assembly 51 includes a support plate 511 and a top plate 512 . The support plate 511 is fixedly mounted on the top of the base 1 , the top plate 512 is fixedly mounted on the top of the support plate 511 , and the drive assembly 52 is assembled on the top plate 512 .

[0039] Personnel can start the motor 521, and the output shaft of the motor 521 will drive the opposing screw rod 524 to rotate. Since the opposing screw rod 524 adopts a relative screw direction, the upper guide plate 522 and the lower guide plate 523 can drive the upper base plate 3 and the lower base plate 2 to move relative to each other, thereby completing the mold closing or separation operation.

[0040] Embodiment 3

[0041] like Figure 1-Figure 5 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0042] In this embodiment, the rotating component 71 includes a mounting base 711, a second cylinder 712, a tooth plate 713, a gear 714, and a rotating shaft 715. The bottom of the lower base plate 2 is fixedly installed with a penetrating rotating shaft 715, the bottom of the rotating shaft 715 is fixedly installed with a gear 714, the bottom of the lower base plate 2 is fixedly installed with a mounting base 711, the back of the mounting base 711 is fixedly installed with a second cylinder 712, and the output end of the second cylinder 712 is docked with a tooth plate 713, the tooth plate 713 and the gear 714 are meshed with each other, and the material picking component 72 is assembled on the top of the rotating shaft 715.

[0043] When the material taking component 72 has finished taking the material, the device can proceed to the second stage of operation by rotating the component 71;

[0044] The second cylinder 712 is started, and the output end of the second cylinder 712 pushes the tooth plate 713, and then the tooth plate 713 completes the transmission to the gear 714, and then the gear 714 can drive the rotating shaft 715 to rotate, and complete the driven rotation of the material taking component 72.

[0045] In this embodiment, the material picking assembly 72 includes a mounting frame 721, a mounting block 722, a first cylinder 723, and a clamping plate 724. The mounting frame 721 is fixedly mounted on the top of the rotating shaft 715, and the first cylinder 723 is fixedly mounted on the front and back sides of the mounting frame 721. The output end of the first cylinder 723 is docked with a mounting block 722 that docks with each other, and the same side of the mounting block 722 is fixedly mounted with a clamping plate 724 that is assembled with each other, and the clamping plate 724 is provided with a docking material picking port 7241.

[0046] During the operation, the first cylinder 723 is started, and the first cylinder 723 drives the clamping plates 724 to move relative to each other, so that the material taking opening 7241 between the clamping plates 724 completes the clamping and extraction of the injection molded parts;

[0047] By combining the above contents, the rotating shaft 715 drives the mounting frame 721 to rotate, and then the first cylinder 723 and the clamping plate 724 in the mounting frame 721 rotate synchronously, and the injection molded part clamped by the clamping plate 724 can be driven to rotate and rotate to the top of the cooling trough body 9.

[0048] In this embodiment, an injection molding mechanism 4 is fixedly mounted on the top of the upper base plate 3 , and an output end of the injection molding mechanism 4 is connected to the inside of the upper mold body 31 .

[0049] During this process, the raw material is injected into the upper mold body 31 through the injection molding mechanism 4 , and the injection molding is completed by utilizing the mold groove between the upper mold body 31 and the injection mold groove 211 .

[0050] In this embodiment, the lifting assembly 8 also includes a shaft seat 82 and a pin 84. Two sets of shaft seats 82 are fixedly installed at the bottom of the mesh plate 86 and the top of the guide base plate 83. Pins 84 assembled and connected to the shaft seats 82 are docked and installed at both ends of the support rod 85.

[0051] When the injection molded part has finished cooling, the personnel can start the third cylinder 81 to carry out the conduction operation. During this period, when the guide base plate 83 is moving, the support rod 85 can be pushed. Since the two ends will then be able to cooperate with each other through the shaft seat 82 and the pin shaft 84, the mesh plate 86 can be pushed, prompting it to complete the upgrading movement.

[0052] The working principle and use process of this utility model:

[0053] During this period, the raw material is injected into the upper mold body 31 through the injection molding mechanism 4, and the injection molding is completed by using the mold groove between the upper mold body 31 and the injection mold groove 211. When the molds need to be separated, the personnel can start the motor 521, and the output shaft of the motor 521 will drive the opposing screw rod 524 to rotate. Since the opposing screw rod 524 adopts a relative screw direction, the upper guide plate 522 and the lower guide plate 523 can drive the upper base plate 3 and the lower base plate 2 to move relative to each other, completing the separation operation;

[0054] During this period, the first cylinder 723 is started, and the first cylinder 723 drives the clamping plate 724 to move relative to each other, so that the material taking port 7241 between the clamping plates 724 completes the clamping and extraction of the injection molded parts. When the material taking component 72 finishes taking the materials, the device can perform the second operation through the rotating component 71, and start the second cylinder 712. The output end of the second cylinder 712 pushes the tooth plate 713, and then the tooth plate 713 completes the transmission to the gear 714. At that time, the gear 714 can drive the rotating shaft 715 to rotate, and the injection molded parts extracted by the material taking component 72 are moved to the top of the cooling tank body 9, and then the injection molded parts below are carried out, and then the injection molded parts fall into the cooling tank body 9 for cooling;

[0055] After cooling, start the third cylinder 81, which pushes the guide bottom plate 83. The horizontal movement of the guide bottom plate 83 is used to complete the action on the support rod 85, so that the support rod 85 can push the mesh plate 86. In this way, the injection molded parts on the mesh plate 86 can be lifted, and then the personnel can directly extract the injection molded parts.
