Description

Technical Field

[0001] The present application relates to the field of fluororubber watch strap processing, and in particular, to a fluororubber watch strap molding die. Background Art

[0002] Fluororubber watch straps are made of synthetic rubber containing fluorine atoms. They have excellent heat resistance, oxidation resistance, oil resistance and chemical resistance. They are denser than ordinary silicone wristbands on the market, feel better and softer, and can be bent at will, so they will better fit the curve of the wrist when worn, and are more skin-friendly and comfortable. Fluororubber watch straps need to be processed and shaped using molds.

[0003] Announcement No. CN 215040190 U discloses a rapid prototyping mold for processing fluororubber watch straps. The fluororubber watch straps are stamped and formed by setting a stamping plate to adjust the stamping mold to the optimal position, thereby reducing the number of stamping times and reducing the production cost of the fluororubber watch straps. A demolding box and an ejector are set to eject from the bottom of the molding groove to avoid manual demolding, saving time and effort and improving the production efficiency of the fluororubber watch straps.

[0004] However, there are some defects in the above scheme: in the above scheme, a second servo motor is set to drive the screw to push the ejector plate to eject the material. The added second servo motor is not only costly, but also increases the operation steps, affecting the processing efficiency. In addition, the fixed base with a fixed height is difficult to adapt to the comfortable and convenient use of workers of different heights. Utility Model Content

[0032] See also Figure 1 , 2 , 3 and 4, the molding die assembly 100 includes a fixed seat 110, a lower die 120, a fixed frame 130, a hydraulic cylinder 150, an upper die 160, an ejector frame 170 and an elastic member 180, the lower die 120 is arranged in the fixed seat 110, the fixed frame 130 is arranged at the top of the fixed seat 110, the hydraulic cylinder 150 is arranged at the top of the fixed frame 130, the upper die 160 is installed at the bottom of the hydraulic cylinder 150, the ejector frame 170 slides through the fixed seat 110, and the ejector frame 170 extends into the lower die 120.

[0033] Among them, the ejector frame 170 includes a sliding rod 171 and an ejector rod 172. The sliding rod 171 slides through the fixed seat 110, and the ejector rod 172 slides through the lower mold 120. The ejector rod 172 is fixedly connected to the sliding rod 171. By setting the sliding rod 171 and the ejector rod 172, the sliding rod 171 can drive the ejector rod 172 to move when it slides, and the ejector rod 172 is used to fix the fluororubber strap.

[0034] In a specific implementation scheme, a top plate 1721 is provided on the top of the ejection rod 172, and a sink 122 is opened in the lower mold 120. The top plate 1721 and the sink 122 are adapted to each other. By providing the top plate 1721 and the sink 122, the top plate 1721 can increase the contact area with the product, making it easier to eject and reduce damage. At the same time, the sink 122 is used to accommodate the top plate 1721 during the stamping process.

[0035] Specifically, the elastic member 180 includes a spring 181 and a limit plate 182. The limit plate 182 is fixedly connected to the top of the sliding rod 171. The spring 181 is sleeved on the surface of the sliding rod 171. By setting the spring 181 and the limit plate 182, the elastic recovery effect of the spring 181 is used to push the limit plate 182, and the limit plate 182 pushes the sliding rod 171, so that the sliding rod 171 drives the ejection rod 172 and the top plate 1721 to move and eject the product.

[0036] In this embodiment, a groove 113 is opened on the top of the fixing seat 110, and the spring 181 abuts between the inner wall of the groove 113 and the limiting plate 182. The groove 113 and the limiting plate 182 are adapted to each other. The groove 113 is provided to accommodate the squeezed spring 181 and the limiting plate 182, thereby ensuring normal stamping and forming.

[0037] In a specific embodiment, a guide rod 161 is slidably sleeved on the end of the upper mold 160, and the guide rod 161 is fixedly connected to the fixing seat 110 and the fixing frame 130. The guide rod 161 is provided to guide the upper mold 160 to move stably and linearly along the guide rod 161.

[0038] See also Figure 1 and 4 The support assembly 200 includes a base plate 210 , an electric push rod 220 and a locking member 240 . The electric push rod 220 is disposed on the top of the base plate 210 , and the locking member 240 is disposed between the base plate 210 and the fixing seat 110 .

[0039] Among them, the locking member 240 includes a fixed sleeve 241, a sliding support plate 242 and a clamping rod 243. The fixed sleeve 241 is fixedly connected to the base plate 210, one end of the sliding support plate 242 is slidably set in the fixed sleeve 241, and the clamping rod 243 passes through the fixed sleeve 241 and the sliding support plate 242. By setting the fixed sleeve 241, the sliding support plate 242 and the clamping rod 243, the sliding support plate 242 can slide up and down in the fixed sleeve 241, and then be locked with the clamping rod 243 to fix the height.

[0040] In a specific implementation scheme, the sliding support plate 242 is provided with a plurality of positioning holes 2421, and the clamping rod 243 slides through the positioning holes 2421. By setting the positioning holes 2421, the clamping rod 243 can pass through the positioning holes 2421 to make the positioning locking more stable, and the height distance adjusted each time by the electric push rod 220 is the same as the spacing between the upper and lower positioning holes 2421.

[0041] The working principle of the fluororubber strap forming mold is as follows: during use, the fluororubber to be processed is placed in the forming groove of the lower mold 120, and the hydraulic cylinder 150 is started. The hydraulic cylinder 150 drives the upper mold 160 to move downward for stamping. At the same time, the upper mold 160 squeezes the limit plate 182, and the limit plate 182 squeezes the spring 181 into the groove 113. At the same time, the limit plate 182 pushes the sliding rod 171, and the sliding rod 171 drives the ejector rod 172 and the top plate 1721 to move downward, and the top plate 1721 enters the sink 122. After the stamping is completed, the upper mold 160 rises, and the upper mold 160 is used. The elastic recovery effect of the spring 181 pushes the limit plate 182, and the limit plate 182 pushes the sliding rod 171, so that the sliding rod 171 drives the ejection rod 172 and the top plate 1721 to move and fix the product, which is convenient for taking materials without unnecessary operations and reduces costs. Furthermore, when used by people of different heights, first start the electric push rod 220 to remove the clamping rod 243, and the electric push rod 220 drives the fixed seat 110 to move and adjust the height, and then the clamping rod 243 is passed through the fixed sleeve 241 and the positioning hole 2421 to achieve stable support and improve practicality.

[0042] It should be noted that the specific model specifications of the hydraulic cylinder 150 and the electric push rod 220 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.
