Description

Technical Field

[0001] The utility model relates to the technical field of heart rate lens production, in particular to a core-pulling structure of a double-color mold heart rate lens for a watch. Background Art

[0002] Currently, the heart rate detection devices on the market emit infrared rays through the heart rate detection lens to the human body's blood vessels. The infrared rays are reflected on the blood vessels and the blood flow signal is returned to the heart rate detection device through the heart rate detection lens. The heart rate detection device processes the signal to obtain the real-time heart rate value of the human body.

[0003] The lens and the shell are processed simultaneously by mold injection molding. During the processing, the movement of the mold at the link where the lens and the shell are fixed can easily cause the two to be misaligned. At the same time, the internal structure of the mold is relatively complex and there are many auxiliary components. While these auxiliary components ensure the processing accuracy, they also complicate the fixation of the lens and the shell during the processing, affecting the processing stability and reducing the processing speed.

[0020] The embodiment of the present application provides a core-pulling structure for the heart rate lens of a two-color mold for a watch, which effectively solves the problem that the internal structure of the mold is relatively complex and there are many auxiliary components. While ensuring the processing accuracy, these auxiliary components also make the fixation of the lens and the shell during the processing process complicated, affecting the processing stability and reducing the processing speed. First, the second slider is driven to move in the opposite direction inside the connecting plate, and the second slider drives the inclined plate to move in the opposite direction inside the groove to reduce the friction on the lifting module. The lifting module drives the lens to slide downward and then squeezes it toward one side of the sleeve column through the second slider. The end of the lifting module rubs against the inclined plate, and the inclined plate generates an upward thrust on the lifting module. The lifting module slides upward inside the sleeve column, and the lifting module drives the lens to move upward. During the first injection molding, the lifting module sinks first, and during the second injection molding, the lifting module drives the lens to rise, gradually plasticizing, making the connection of components more convenient and stable, thereby speeding up the production speed.

[0021] Example

[0022] like Figure 1 - Figure 5 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the internal structure of the mold is relatively complex and there are many auxiliary components. While these auxiliary components ensure the processing accuracy, they also make the fixation of the lens and the shell during the processing complicated, affect the processing stability, and reduce the processing speed. The overall idea is as follows:

[0023] In view of the problems existing in the prior art, the utility model provides a core-pulling structure for a double-color mold heart rate lens of a watch, comprising an upper mold 11, a lower mold 12 and a base 13. An injection mold core is fixedly installed on the top of the lower mold 12. The injection mold core comprises a support frame 16, a lifting module 23 and a sleeve column 25. A fixing rod 24 is fixedly installed on the bottom end of the lifting module 23. The lower mold 12 is fixedly connected to the base 13. At the same time, a hydraulic drive mechanism is installed on the top of the upper mold 11. A pouring system is installed inside the upper mold 11 to introduce plastic melt into the mold cavity. The lens is first installed on the top of the lifting module 23 through the upper mold 11. Three different types of lenses can be installed on the top of the lifting module 23. A groove 26 is provided at the bottom end of the sleeve column 25. A connecting plate 19 is fixedly installed inside the lower mold 12. A second slider 18 is slidably installed on the top of the connecting plate 19. A first slider 15 is slidably installed on the top of the second slider 18.

[0024] A push rod 14 is fixedly installed on the top of the first slider 15, an inclined plate 22 is fixedly installed on the side end of the second slider 18, a reset rod 21 is fixedly installed inside the connecting plate 19, and a support frame 16 is fixedly installed on the top of the lower mold 12, so that the push rod 14 applies downward pressure to the first slider 15, and the first slider 15 moves downward. The end of the first slider 15 is an arc-shaped design, and the interior of the second slider 18 is a downwardly concave conical design. The end of the first slider 15 slides downward inside the second slider 18 and rubs against the interior of the second slider 18, generating a horizontal thrust on the second slider 18, so that the second slider 18 slides on the top of the connecting plate 19. The top of the supporting frame 16 is movably installed with a shell 17, the second slider 18 and the connecting plate 19 are split designs, the interior of the connecting plate 19 is a hollow design, the second slider 18 is a T-shaped design, the interior of the second slider 18 is a downwardly concave conical design, and rubs against the end of the first slider 15, and the inclined plate 22 is obliquely installed on the side end of the second slider 18.

[0025] Working principle:

[0026] In the first step, the lower mold 12 is fixedly connected to the base 13, and a hydraulic drive mechanism is installed on the top of the upper mold 11. A pouring system is installed inside the upper mold 11 to introduce plastic melt into the cavity. The lens is first installed on the top of the lifting module 23 through the upper mold 11. Three different types of lenses can be installed on the top of the lifting module 23. The upper mold 11 is driven to move downward, and the upper mold 11 moves downward to extrude the push rod 14, so that the push rod 14 applies downward pressure to the first slider 15, and the first slider 15 moves downward. The end of the first slider 15 is an arc-shaped design, and the interior of the second slider 18 is a downwardly concave conical design. The end of the first slider 15 slides downward inside the second slider 18 and rubs against the interior of the second slider 18, generating a horizontal thrust on the second slider 18, allowing the second slider 18 to slide on the top of the connecting plate 19.

[0027] In the second step, the second slider 18 slides on the top end of the connecting plate 19, and the second slider 18 drives the inclined plate 22 to slide inside the groove 26. At the same time, the second slider 18 slides inside the connecting plate 19 to squeeze the reset rod 21, and the reset rod 21 is compressed by the force. At the same time, the top end of the reset rod 21 applies a reverse thrust to the second slider 18, and the inclined plate 22 slides inside the groove 26. Since the inclined plate 22 is obliquely installed at the side end of the second slider 18, the end of the lifting module 23 rubs against the inclined plate 22, and the inclined plate 22 pushes the lifting module 23 upward. The lifting module 23 slides upward inside the sleeve column 25, and the lifting module 23 drives the lens to move upward and flush with the top of the support frame 16. The upper mold 11 and the lower mold 12 are fitted to complete the plasticity of the shell 17, and the lens is assembled and installed with the support frame 16. By driving the second slider 18 to move in the opposite direction inside the connecting plate 19, the second slider 18 drives the inclined plate 22 to move in the opposite direction inside the groove 26, thereby reducing the friction on the lifting module 23. The lifting module 23 slides downward on the top of the sleeve column 25, and the lifting module 23 drives the lens to slide downward.

[0028] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
