Description

Technical Field

[0001] This utility model relates to the field of mold technology for manufacturing the inner shell of a hair growth device, and in particular to a mold for manufacturing the inner shell of a hair growth device. Background Technology

[0002] Hair loss has become a common concern in daily life. Common causes include emotional stress, genetic factors, and localized lesions. Any factor affecting hair follicle development can lead to hair loss. The mechanism is as follows: hair follicles receive nutrition and oxygen from capillaries, but this is regulated by the nervous system. When a person is under mental stress, the sympathetic nervous system is excited, capillaries constrict, and blood supply to the hair follicles is impaired. Malnutrition of the hair can then cause hair loss. Currently, treatment for these conditions relies on medication, injections, and hair regrowth devices.

[0003] Existing hair regrowth devices are generally laser hair regrowth devices. They increase the activity of adenosine triphosphate (ATP) in subcutaneous tissue, promote tissue metabolism, help improve blood circulation, and deliver oxygen and nutrients to hair follicles to prevent hair loss. They also effectively stimulate hair follicles, regulate sebum secretion to accelerate hair growth, and strengthen the hair itself, including its density and elasticity. Scientific research and clinical data have proven that laser treatment can increase hair density by 40-60% and achieve a success rate of stopping hair loss of up to 85%. Laser hair regrowth devices are painless, non-invasive, require no consumables, and are simple and efficient to use.

[0004] Most existing hair growth devices have a helmet-like structure, which generally includes an inner shell and an outer shell. However, in the existing molds used to make the inner shell, it is often necessary to manually separate the molded parts in the recessed areas of the inner shell after molding, which greatly reduces processing efficiency.

[0005] Therefore, in this utility model patent application, the applicant has carefully researched a mold for making the inner shell of a hair growth device to solve the above problems. Utility Model Content

[0006] This utility model addresses the shortcomings of the existing technology mentioned above. Its main purpose is to provide a mold for manufacturing the inner shell of a hair growth device. It can automatically separate the recessed molded part from the recessed part on the side of the inner shell of the hair growth device during demolding. It has a high degree of automation and does not require separate separation of the recessed molded part, which greatly saves processing efficiency.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A mold for manufacturing the inner shell of a hair growth device includes an upper mold plate and a lower mold plate; the lower end face of the upper mold plate is provided with an inclined guide rod, which is inclined downwards; an upper mold core is provided on the upper mold plate, and a forming block protrudes downwards from the lower end face of the upper mold core.

[0009] The lower template is provided with a lower mold core. The upper end face of the lower mold core is recessed to the bottom, and the upper end face of the lower template is recessed to the bottom, with a sliding groove. A slider that can move closer to or further away from the lower mold core is slidably installed in the sliding groove. The lower mold core has a through hole. The through hole and the sliding groove are located on the same axial direction. The two ends of the through hole are respectively connected to the cavity and the sliding groove. A recessed forming part for forming the recessed side of the inner shell of the hair growth device is slidably installed in the through hole. The outer end of the recessed forming part is connected to the slider. The slider is provided with an inclined groove adapted to the inclined guide rod.

[0010] The upper and lower templates are connected, the upper and lower mold cores are connected, the forming block is adapted to the cavity, and the outer surface of the forming block and the inner wall of the forming cavity form a forming cavity for forming the inner shell of the hair growth device. The inclined guide rod is adapted to the inclined groove from top to bottom. At the same time, the slider slides towards the lower mold core until the bottom end of the inclined guide rod abuts against the inner bottom wall of the inclined groove. At this time, the inner end of the recessed forming part extends into the cavity.

[0011] The upper and lower templates separate, the upper and lower mold cores separate, the forming block disengages from the cavity, and the inclined guide rod disengages from the inclined groove from bottom to top. At the same time, the slider slides away from the lower mold core until the bottom end of the inclined guide rod completely disengages from the inclined groove. At this time, the inner end of the recessed forming part retracts into the through hole.

[0012] As a preferred embodiment, the lower template is provided with a groove at each of the four corners of the lower mold core, and a slider is provided in each groove;

[0013] The lower mold core is provided with a through hole at each of its four corners, and a recessed forming part is provided in each through hole. Each recessed forming part is connected to a corresponding slider.

[0014] As a preferred embodiment, the lower template is provided with a sliding groove on each of the front and rear sides corresponding to the lower mold core, and a sliding block is provided in each sliding groove;

[0015] The lower mold core is provided with a through hole on each of its front and rear sides, and a recessed forming part is provided in each through hole. Each recessed forming part is connected to a corresponding slider.

[0016] As a preferred embodiment, the outer end of the recessed molding part is detachably connected to a slider.

[0017] As a preferred embodiment, a limiting block for preventing the slider from moving up and down is detachably connected inside the slide groove. A limiting sliding groove is formed between the lower end face of the limiting block and the slide groove. The slider has a limiting step portion, which abuts against the lower part of the limiting block and reciprocates within the limiting sliding groove.

[0018] As a preferred embodiment, the slide groove is provided with a stop to limit the displacement stroke of the slider.

[0019] As a preferred embodiment, the lower end face of the upper template is recessed upward to provide a clearance groove for the displacement of the slider, and the inclined guide rod is located inside the clearance groove and extends out of the upper template.

[0020] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, it mainly achieves automatic separation of the concave molded part from the concave side of the inner shell of the hair growth device during demolding by cooperating with the inclined guide rod, inclined groove, slider and concave molding part. It has a high degree of automation and does not require separate separation of the concave molding part, which greatly saves processing efficiency.

[0021] Secondly, the stopper prevents the slider from moving outward, and the limit block prevents the slider from moving up and down during the displacement process, thereby ensuring the stability and reliability of the slider during the displacement process.
