[0039] Embodiment 2

[0040] Based on Example 1, please refer to Figure 1 , Figure 6 and Figure 7As shown, the specific improvements are as follows: the demolding assembly includes two cylinders 15 fixed on the top of the base 1, and are respectively located on the front and rear sides of the lower die base 3. A cavity 16 is provided inside the lower die base 3. The middle die 5 is composed of a first arc module 51 and a second arc module 52. The bottoms of the first arc module 51 and the second arc module 52 are fixedly connected with a fixing plate 17, and the bottom of the fixing plate 17 is slidably connected to the bottom of the inner wall of the cavity 16.

[0042] Through the setting of the above structure, the cylinder 15 drives the first arc module 51 and the second arc module 52 to move in opposite directions, first demolding the edge of the rubber ring, and then moving the anti-stripping rubber ring upward through the ejection mechanism 19, thereby reducing the difficulty of demolding, avoiding damage to the anti-stripping rubber ring, and improving the quality of the product after molding.

[0043] Embodiment 3

[0044] In conjunction with Example 1 and Example 2, please refer to Figure 1 and Figure 8 As shown, the specific improvements are as follows: a cooling cavity 25 is provided inside the first arc module 51 and the second arc module 52, and a heat-conducting layer 26 is provided on the inner wall of the middle mold 5. The heat-conducting layer 26 is made of graphite material, which has good thermal conductivity and improves the cooling efficiency. The surfaces of the first arc module 51 and the second arc module 52 are provided with multiple water inlet connectors 27, which are connected to the external water supply mechanism. A water outlet pipe is also provided on one side of the surface of the middle mold 5 to facilitate water circulation.

[0045] Through the arrangement of the above structure, the heat-conducting layer 26 conducts heat to the cooling cavity, and simultaneously supplies water to the cooling cavity 25 of the middle mold 5 through multiple water inlet connectors 27, so that the cooling temperatures of various areas are close, the product can be cooled evenly and quickly, and the two materials can be firmly combined together, thereby improving work efficiency and quality after molding.

[0046] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment compatible with the equipment can be used.

[0047] When in use, multiple anti-slip tooth boxes 7 are respectively installed on the edges of the boss 4, and then the fixed pressure cover 8 is placed on the anti-slip tooth box 7. After limiting the anti-slip tooth box 7, the worker places the soft glue on the inner side of the middle mold 5, presses the soft glue molding mold 21 on the top of the lower mold base 3, drives the upper mold base 2 to move downward through the external driving mechanism, and presses the soft glue through the soft glue molding mold 21. After the pressing is completed, the upper mold base 2 and the soft glue molding mold 21 are moved away from the lower mold base 3, and the second motor 11 is started to drive the screw rod 12 to move forward. The cleaning assembly 9 is driven to move to the top of the middle mold 5 under the sliding guidance of the movable block 13. The midpoint of the first motor 94 is consistent with the midpoint of the boss 4. Then the first motor 94 drives the support plate 96 to rotate through the rotating shaft 95. The support plate 96 drives the outer blade 97 and the inner blade 98 to rotate to cut the overflowed rubber and the rubber ring body. Then, during the rotation process, the scraper 99 removes the excess rubber from the fixed gland 8 and the middle mold 5. The excess rubber is automatically removed, saving time and effort.

[0048] After the soft glue is cleaned, the cleaning component 9 is restored to its original position, and then the hard glue strip is rolled on the top of the soft glue, and the hard glue molding mold 22 is pressed on the top of the lower mold base 3. Similarly, the upper mold base 2 moves downward to composite the hard glue and the soft glue. After molding, the same operation is performed. After the overflowed glue is processed, the cylinder 15 is started to drive the first arc module 51 and the second arc module 52 to separate. The edge of the anti-stripping rubber ring is demolded first, and then the electric push rod 191 is started to drive the annular plate 193 to move upward. The annular plate 193 drives the ejector rod 194 to move upward, and the anti-stripping rubber ring after the edge is demolded is ejected upward to reduce the difficulty of demolding;

[0049] During the composite molding process of the hard rubber and the soft rubber, the external water supply mechanism is connected to multiple water inlet connectors 27 to simultaneously deliver cooling water to the cooling cavity 25 in different areas, thereby avoiding uneven cooling temperature due to the order in which the cooling water passes through a single water inlet. The heat conductive layer 26 accelerates the conduction of heat to the cooling cavity 25, and then the cooling water can quickly and evenly cool the product, so that the two materials can be firmly combined together.

[0050] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
