AI Technical Summary
How to release the mold after the frame is formed is an urgent problem, because the hard rubber part of the frame is set up around the inner side of the frame, which makes it impossible to directly eject the product directly using a thimble.
A molding mold for a frame is designed, including a top-down panel, a pad plate, an up-moving mold, a down-setting mold, a thimble plate and a bottom plate. The upper mold core is embedded at the bottom of the upper moving die, and the lower mold core is embedded at the bottom fixed die. There are notches at both ends of the lower mold core along the length direction, and there are lower mold grooves and V-shaped grooves for forming the hard rubber part of the mirror frame between the two notches. Through the design of oblique top blocks and inserts, the mold release of the frame is achieved.
It realizes efficient mold release of the frame, avoids the problem of product being stuck during the molding process, and improves production efficiency.

[0032] Reference Figure 2-7 As shown, the utility model discloses a molding die for a mirror frame, comprising a panel 10, a pad 20, an upper movable mold 30, a lower fixed mold 40, a ejector plate 50 and a bottom plate 60 from top to bottom, an upper mold core 301 is embedded at the bottom of the upper movable mold 30, the upper mold core 301 is provided with an upper molding groove 3011 for molding the soft rubber part of the mirror frame 70, a lower mold core 401 is embedded in the lower fixed mold 40, the lower mold core 401 is provided with notches at both ends along the length direction, the lower mold core 401 is provided with a lower molding groove 4011 and a V-shaped groove 4012 for molding the hard rubber part of the mirror frame 70 between the two notches, when the molds are closed, the upper mold core 301 and the lower mold core 401 are closed, and the upper molding groove 3011, the lower molding groove 4011 and the V-shaped groove 4012 are closed to form the soft rubber part and the hard rubber part of the molded mirror frame 70. Furthermore, the lower fixed mold 40 is provided with side pull-out mechanisms on both sides of the lower mold core 401, and the side pull-out mechanisms include side forming blocks 402. Specifically, the upper movable mold 30 is provided with inclined guide blocks on both ends of the upper mold core 301 along the length direction, and the side forming blocks 402 are provided with inclined guide grooves. When the molds are closed, the side forming blocks 402 on both sides are pushed close to the lower mold core 401 through the cooperation of the guide blocks and the inclined guide grooves. The end surfaces of the side forming blocks 402 close to the lower mold core 401 are provided with protrusions, which are used to form fixing holes on both sides of the molding frame 70, and the fixing holes are used to install straps.
[0033] Reference Figure 2-7As shown, the lower mold core 401 has a detachable mounting insert 4013, and the edge of the insert 4013 extends out of the lower molding groove 4011 and the notch to form a first extension portion. The lower mold core 401 is provided with an inclined top block 4015, and the inclined top block 4015 extends into the V-shaped groove 4012 away from the side of the insert 4013 to form a second extension portion. Specifically, during mold closing and injection molding, the first extension portion of the insert 4013 is used to form the mounting groove 701 of the hard rubber part of the frame 70, and the second extension portion of the inclined top block 4015 is used to form the mounting groove 701 of the hard rubber part of the frame 70 at the nose pad position.
[0034] Reference Figure 2-7 As shown, the inclined ejector block 4015 can slide through the lower mold core 401, the lower fixed mold 40 is connected to the ejector plate 50, and the bottom of the insert 4013 is detachably installed with an ejector pin 4017, which can slide downward through the lower mold core 401 and is connected to the ejector plate 50. Specifically, a V-shaped slide groove is installed on the ejector plate 50, and the inclined ejector block 4015 includes two inclined ejector blocks, and the lower end of the inclined ejector block 4015 can be slidably installed in the slide groove. The lower ends of the two inclined ejector blocks 4015 can slide apart or close along the slide groove. When the ejector plate 50 pushes the inclined ejector block 4015 upward, the lower ends of the two inclined ejector blocks 4015 are separated along the slide groove and the upper end of the inclined ejector block 4015 is ejected from the lower mold core 401, and the second extension portion pushes the mirror frame 70 from The V-shaped groove 4012 of the lower mold core 401 is disengaged; at the same time, the ejector plate 50 pushes the ejector 4017 upward to push the insert 4013 out of the lower mold core 401, and the first extension portion pushes the frame 70 out of the lower molding groove 4011 of the lower mold core 401. Since the ejector 4017 and the insert 4013 are detachable, the product and the insert 4013 are taken out at the same time, and then the insert 4013 is removed from the product by the manipulator to realize the demoulding of the product. Furthermore, two positioning columns 4014 are provided on the insert 4013, and the positioning columns 4014 are used by the manipulator to remove the insert 4013 from the product and to facilitate the insert 4013 to be put back into the lower mold core 401.

When the mold is closed, the positioning grooves 3012 and the positioning protrusions 4016 cooperate to achieve precise closure of the upper mold core 301 and the lower mold core 401, avoiding the inability to form the product due to unsealed closure.
[0036] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
