Specifically, the second lower mold 40 is provided with a second molding assembly. The second molding assembly includes two second molding blocks 33 arranged opposite to each other, and the two second molding blocks 33 can move towards and away from each other. The surfaces of the second molding blocks 33 that are close to each other are second molding surfaces. A second molding groove is provided on the second molding surface. After the two second molding blocks 33 are close to each other, the second molding grooves on the two second molding blocks 33 can cooperate to form a second molding cavity; the second runner 31 is connected to the second molding cavity.

[0029] Furthermore, the second upper mold 30 is provided with an inclined ejector block, and the inclined ejector block is used to press the second molding block 33 when the second upper mold 30 and the second lower mold 40 are closed.

[0030] On the basis of the above structure, when using the molding mold of the two-color liquid silicone accessories of the utility model, the first flow channel 11 of the first mold can be connected to the first group of liquid silicone pipelines on the silicone injection machine, and the second flow channel 31 of the second mold can be connected to the second group of liquid silicone pipelines on the silicone injection machine. In this way, the first flow channel 11 and the second flow channel 31 can respectively guide liquid silicone of different colors into the first upper mold 10 and the second upper mold 30.

[0031] In the above process, the first upper mold 10 and the first lower mold 20 are closed under the drive of the driving cylinder or the oil cylinder. At this time, the first upper mold 10 is pressed downward to drive the two first molding blocks on the first lower mold 20 to approach each other. In the process of approaching each other, the first molding grooves of the two first molding blocks cooperate to form a first molding cavity. The above-mentioned first runner 11 can enter the first molding cavity to realize accessory molding in the first molding cavity.

[0032] The second upper mold 30 and the second lower mold 40 are closed under the drive of the driving cylinder or the oil cylinder. At this time, the second upper mold 30 is pressed downward to drive the two second molding blocks 33 on the second lower mold 40 to approach each other.

The above-mentioned second runner 31 can enter the second molding cavity to realize accessory molding in the second molding cavity.

[0033] It should be noted that the above-mentioned first molding cavity and second molding cavity can be different accessories of the same product. Therefore, the first molding cavity of the first mold and the second molding cavity of the second mold are used to mold different accessory cavities of the same finished product, and the accessories are assembled after molding, which can effectively improve the molding efficiency.

[0036] When the first upper mold 10 moves downward toward the first lower mold 20, the first mold is in a mold closing state. During the mold closing process, the inclined ejector block 13 on the first upper mold 10 can press the first molding segment 141 downward, driving the two first molding segments 141 to move toward each other. The first molding segment 141 and the second molding segment 142 are connected by a structure such as a latch or a bolt, so that when the first molding segment 141 moves toward each other, the second molding segment 142 can be driven to move toward each other.

A heating wire is placed in each heating wire groove 51, and then the heating wire can be powered on for heating. In this way, the heating distribution is uniform. Through the setting of the heating plate 50, the liquid silicone in the first flow channel 11 of the first upper mold 10 can be kept in a liquid introduction state in a heating environment.

[0043] Furthermore, a cooling plate 60 is provided in the first upper mold 10 and the second upper mold 30, and a plurality of cooling channels 61 are provided in the cooling plate 60.
