[0002] As a common personal care product in daily life, the design of the handle of a manual razor must consider not only the comfort of holding it but also its aesthetic appeal. Among these factors, the curvature of the handle is one of the key factors affecting both the grip and the appearance.

[0003] In existing injection molding processes for manual razor handles, injection molds designed for the curved surfaces of the handles have significant drawbacks. The molds lack efficient demolding mechanisms, requiring manual removal of the molded part after molding. This operation is not only cumbersome and inconvenient, but also, due to the inefficiency and instability of manual operation, greatly reduces the production pace and severely impacts the overall production efficiency of razor cover injection molding.

[0004] Therefore, it is necessary to provide an injection molding mold for the curved surface of a manual razor handle to solve the above-mentioned technical problems. Utility Model Content

[0027] Please see Figures 1-4 The embodiments provided by this utility model are as follows:

[0028] A manual razor handle curved surface injection molding mold, comprising:

[0029] The base 1 has support frames 2 fixedly installed on both sides of the bottom of the base 1. The fixed mold 3 is fixedly installed on the top of the base 1. The bottom of the base 1 has a through groove 17. The fixed plate 16 is fixedly installed between the two support frames 2. The fixed mold 3 has a mold cavity 5 inside. The fixed mold 4 is set above the top of the fixed mold 3. The bottom of the inner wall of the mold cavity 5 has a number of sliding holes 22 evenly and at equal intervals, and the sliding holes 22 are connected to the inside of the through groove 17.

[0030] A push rod 19 is slidably inserted into the sliding hole 22. A top plate 15 is fixedly installed at the bottom end of the push rod 19. A spring 20 is sleeved on the outer wall of the push rod 19 between the top plate 15 and the bottom of the fixed mold 3. A second electric telescopic rod 14 is fixedly installed on the top of the fixed plate 16. An injection tube 8 is provided on the top of the moving mold 4.

[0031] A through hole 12 is provided on the rear side of the top of the base 1. A mounting bracket 13 corresponding to the position of the through hole 12 is fixedly installed on the rear side of the bottom of the base 1. A first electric telescopic rod 11 is fixedly installed on the top of the mounting bracket 13. A positioning block 9 is fixedly installed on the back of the moving mold 4. The positioning block 9 is fixedly connected to the drive end of the first electric telescopic rod 11 by bolts. The opening and closing action of the moving mold 4 is driven by the first electric telescopic rod 11. The degree of automation is high, avoiding the tediousness and inefficiency of manual operation, and achieving the effect of saving time and effort.

[0032] In one embodiment, symmetrically distributed guide rods 10 are fixedly installed on both sides of the top of the base 1, and symmetrically distributed connecting rods 7 are fixedly installed on both sides of the moving mold 4. A sliding sleeve 6 is fixedly installed at the end of the connecting rod 7 away from the moving mold 4, and the sliding sleeve 6 is slidably sleeved on the outer wall of the guide rod 10. The guide rod 10 plays a limiting role in the movement path of the moving mold 4, which can effectively ensure the positional accuracy and movement accuracy of the moving mold 4 during the opening and closing process.

[0033] In one preferred embodiment, the front and rear sides of the inner wall of the through groove 17 are provided with sliding grooves 18, and the front and back sides of the top plate 15 are fixedly installed with sliders 21, and the sliders 21 are slidably installed on the corresponding sliding grooves 18 to limit the movement path of the top plate 15 and ensure that the top plate 15 and the top rod 19 on its top are accurately reset.

[0034] In one embodiment, the top end of the ejector pin 19 is curved, and the curvature of the top end of the ejector pin 19 matches the curvature of the bottom of the inner wall of the mold cavity 5, without changing the original curvature structure of the mold cavity 5, thus ensuring the forming quality of the tool holder.

[0035] In one preferred embodiment, a sealing sliding sleeve 23 is fixedly installed at the bottom opening of the sliding hole 22 at the bottom of the fixed mold 3, and the sealing sliding sleeve 23 is slidably connected to the ejector rod 19, which can prevent the injection molding material from leaking from the sliding hole 22, ensure the sealing of the mold cavity 5, and improve the molding quality.

[0036] The working principle of this utility model is as follows: All electrical components mentioned are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer for control, and existing publicly available power connection technologies are not elaborated here. Parts not mentioned in this device are the same as or can be implemented using existing technologies. In use, the moving mold 4 is closed on top of the fixed mold 3, making the mold cavity 5 a sealed molding space. Injection material is injected into the mold cavity 5 through the injection tube 8. After the tool holder cools and solidifies in the mold cavity 5, the moving mold 4 is driven to move upwards, leaving the tool holder in the mold cavity 5. Then, the second electric telescopic rod 14 is activated, its driving end extending to contact the bottom of the top plate 15 and pushing it upwards. The movement of the top plate 15 causes the slider 21 to slide along the slide groove 18, simultaneously driving the ejector rod 19 to slide upwards within the slide hole 22. During this process, the top plate 15 moves upwards, compressing the spring 20. As the ejector pin 19 moves upward, it gradually extends into the mold cavity 5, pushing the molding shank out of the mold cavity 5 and completing the demolding operation. After demolding, the drive end of the second electric telescopic rod 14 is reset, and the top plate 15 is reset under the elastic force of the spring 20, which in turn drives the ejector pin 19 to reset, so as to carry out subsequent shank injection molding operations. During the operation of this mold, the ejector pin 19 is moved by the second electric telescopic rod 14, which can automatically complete the demolding of the molding shank in the mold cavity 5 without manual intervention. The structure is simple and the operation is convenient, effectively solving the problem of low production efficiency caused by manual demolding in the injection molding production of razor shank shanks.

[0037] When controlling the opening and closing operation of the moving mold 4 and the fixed mold 3, the first electric telescopic rod 11 can be activated. The driving end of the first electric telescopic rod 11 drives the moving mold 4 to make vertical displacement through the positioning block 9. During the movement of the moving mold 4, the sliding sleeve 6 is driven to slide on the outer wall of the guide rod 10 through the connecting rod 7. The guide rod 10 plays a limiting role in the movement path of the moving mold 4, which can effectively ensure the positional accuracy and movement accuracy of the moving mold 4 during the opening and closing process. In addition, the opening and closing action of the moving mold 4 is completed by the first electric telescopic rod 11, which has a high degree of automation, avoids the tediousness and inefficiency of manual operation, and achieves the effect of saving time and effort, thereby further improving the production efficiency of the tool holder.
