Description

Technical Field

[0001] This utility model relates to the field of injection mold switching technology, specifically a synchronous switching mechanism for a two-color injection mold for plastic products. Background Technology

[0002] In two-color injection molds, a synchronous shifting mechanism refers to a mechanical device that ensures that the moving parts of the mold can rotate precisely, synchronously, and repeatedly from one position to another during the mold opening stroke of the injection molding machine.

[0003] A search of Chinese patent CN206416381U reveals a mold rotation and repositioning platform device, comprising a support plate, a rotating plate, a mold frame, and a mold clamp. The support plate is connected to the rotating plate, and their axes are aligned. The mold frame is arranged on the rotating plate, and the mold clamp is arranged on the mold frame. The rotating plate drives the mold frame to rotate. The support plate is placed on a mold trolley, which pushes the mold into the machine tool working position. The mold rotation and repositioning platform device provided by this patent can provide a changing structure to support the conversion of two or more molds for different molds. This utility model uses a universal mold clamping device that can load most processing molds.

[0004] Based on the above search and existing technology, it was found that the above patent has certain defects. The existing mechanism does not have a dedicated cooling mechanism that can effectively cover the mold cavity, resulting in low cooling efficiency and uneven cooling, which affects production efficiency and product quality. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a synchronous shifting mechanism for two-color injection molds of plastic products.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: An embodiment of this utility model provides a synchronous shifting mechanism for a two-color injection mold for plastic products, including a machine body, a turntable fixedly installed on the machine body, a blowing mechanism on the machine body, and a spraying mechanism on the blowing mechanism. The air blowing mechanism includes a frame plate fixedly installed on the machine body, a fan is provided on the frame plate, a flexible hose is connected to the output end of the fan, a fan housing is fixedly installed on the flexible hose, and a rotating component is provided between the frame plate and the fan housing.

[0007] Furthermore, two lower molds are fixedly installed on the turntable.

[0008] Furthermore, the rotating assembly includes two symmetrically fixed brackets mounted on the frame plate, and a drive motor is provided between the two brackets.

[0009] Furthermore, a fixing block is fixedly installed on the output end of the drive motor.

[0010] Furthermore, a sleeve is fixedly installed on the fixing block, a spring is connected to the inner wall of the sleeve, and a telescopic rod is connected to the end of the spring, with the telescopic rod slidably connected to the sleeve.

[0011] Furthermore, a collar is fixedly installed at the end of the telescopic rod, and a connecting rod is fixedly installed on the fan casing, with the collar and the connecting rod being rotatably connected.

[0012] Furthermore, the spraying mechanism includes a connecting pipe fixedly mounted on the frame plate, and a spray shell is fixedly mounted on the connecting pipe.

[0013] The above-described solution of this utility model has at least the following beneficial effects: 1. In this utility model, by controlling the operation of the fan, the fan generates wind power and delivers it to the inside of the fan housing through a hose. The wind is then sprayed out from the fan housing. The drive motor is controlled to operate, and the output end of the drive motor drives the housing to swing through the fixed block. The housing, through the spring, telescopic rod, collar, and connecting rod, drives the spray shell to swing, so that the wind force sprayed out by the fan housing can evenly cool the plastic product in the lower mold.

[0014] 2. In this utility model, the release agent is delivered to the inside of the spray shell through a connecting pipe by controlling the external delivery equipment. The release agent is then sprayed out by the spray shell onto the lower mold passing through the bottom of the spray shell, thereby facilitating the subsequent demolding process.

[0017] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0018] like Figures 1 to 5 As shown, an embodiment of this utility model provides a synchronous shifting mechanism for a two-color injection mold for plastic products, including a machine body 1, a turntable 2 fixedly mounted on the machine body 1, a blowing mechanism on the machine body 1, and a spraying mechanism on the blowing mechanism. The blowing mechanism includes a frame plate 4 fixedly mounted on the machine body 1, a fan 5 fixedly mounted on the frame plate 4, a flexible hose 6 connected to the output end of the fan 5, a fan housing 7 fixedly mounted on the flexible hose 6, and a rotating assembly shared between the frame plate 4 and the fan housing 7. Two lower molds 3 are fixedly mounted on the turntable 2. The moving component includes two symmetrically fixed brackets 8 mounted on the frame plate 4. A drive motor 9 is fixedly mounted between the two brackets 8. A fixing block 10 is fixedly mounted on the output end of the drive motor 9. A housing 11 is fixedly mounted on the fixing block 10. A spring 12 is connected to the inner wall of the housing 11. A telescopic rod 13 is connected to the end of the spring 12. The telescopic rod 13 is slidably connected to the housing 11. A collar 14 is fixedly mounted on the end of the telescopic rod 13. A connecting rod 15 is fixedly mounted on the fan shell 7. The collar 14 and the connecting rod 15 are rotatably connected.

[0019] In this embodiment of the utility model, the machine body 1 is equipped with a drive device for rotating the turntable 2. In the two-color injection molding of plastic products, the operator controls the machine body 1 to drive the turntable 2 to rotate, thereby facilitating the synchronous repositioning of the lower mold 3. By controlling the operation of the fan 5, the fan 5 generates air force, which is delivered to the inside of the air shell 7 through the hose 6 and sprayed out by the air shell 7. The drive motor 9 is controlled to operate, so that the output end of the drive motor 9 drives the sleeve 11 to swing through the fixed block 10. The sleeve 11 drives the spray shell 17 to swing through the spring 12, telescopic rod 13, collar 14 and connecting rod 15, so that the air force sprayed out by the air shell 7 can evenly cool the plastic products in the lower mold 3 that pass through the bottom of the air shell 7, thereby facilitating the demolding of the plastic products in the lower mold 3 by the operator.

[0020] Figures 1 to 5 As shown, the spraying mechanism includes a connecting pipe 16 fixedly installed on the frame plate 4, and a spray shell 17 is fixedly installed on the connecting pipe 16.

[0021] In this embodiment of the utility model, the connecting pipe 16 is connected to an external mold release agent delivery device. The operator controls the external mold release agent delivery device to deliver the mold release agent through the connecting pipe 16 to the inside of the spray shell 17. The spray shell 17 sprays the mold release agent onto the lower mold 3 at the bottom of the spray shell 17, thereby facilitating the subsequent demolding work.

[0022] Working Principle: In the two-color injection molding of plastic products, the operator controls the machine body 1 to drive the turntable 2 to rotate, thereby facilitating the synchronous repositioning of the lower mold 3. By controlling the operation of the blower 5, the blower 5 generates airflow, which is delivered to the inside of the blower housing 7 through the hose 6 and sprayed out from the blower housing 7. The drive motor 9 is controlled to operate, and the output end of the drive motor 9 drives the sleeve 11 to swing through the fixed block 10. The sleeve 11 drives the spray shell 17 to swing through the spring 12, telescopic rod 13, collar 14 and connecting rod 15. This allows the airflow from the blower housing 7 to evenly cool the plastic product in the lower mold 3 that passes through the bottom of the blower housing 7, facilitating the demolding of the plastic product in the lower mold 3. The operator controls the external delivery of release agent equipment to deliver the release agent to the inside of the spray shell 17 through the connecting pipe 16, and the spray shell 17 sprays the release agent onto the lower mold 3 that passes through the bottom of the spray shell 17.

[0023] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
