[0002] A rubber molding machine is a machine dedicated to the production of rubber products, which mainly includes the following stations: feeding station, molding station, demoulding station and sampling station. In existing rubber molding machines, the feeding station and sampling station are generally manually operated, while the molding station and demoulding station can only mold a batch of samples at a time, and then the mold can be demoulded and sampled before the next production cycle can be carried out, which makes the production efficiency low.

[0044] The first mold unit 1 and the second mold unit 2 are both composed of an upper mold and a lower mold. The first mold unit 1 and the second mold unit 2 can open or close the mold in the injection area; the lower mold can be transported to the first cleaning area 5 and the first material taking area in sequence, or can be transported to the second cleaning area 6 and the second material taking area in sequence; the lower mold cleaning mechanism 11 on the first cleaning area 5 and the second cleaning area 6 can clean the lower mold; the first material taking mechanism 9 and the second material taking mechanism 8 can take out the rubber product on the lower mold; when the injection area is working, at least one of the first mold unit 1 and the second mold unit 2 is in a closed mold state.

[0045] The working process of the above-mentioned fully automatic rubber molding machine is as follows: first, one of the first mold unit 1 and the second mold unit 2 is molded in the injection area, and then the rubber material is injected and molded in the first mold unit 1 and the second mold unit 2. Then, the first mold unit 1 or the second mold unit 2 is molded in the injection area (if the upper mold is connected to the upper and lower driving structures, the upper mold rises to achieve mold opening, which is the prior art), and the lower mold is transported to the material taking area (the first material taking area or the second material taking area) for material taking. After the material taking is completed, the lower mold is transported to the cleaning area (the first cleaning area 5 or the second cleaning area 6) for cleaning. After cleaning, the lower mold waits to enter the injection area to close the mold and realize the next molding;

[0046] After one of the first mold unit 1 and the second mold unit 2 is opened, the other of the first mold unit 1 and the second mold unit 2 is closed in the injection area, so that the work in the injection area is non-stop, thereby greatly improving the production efficiency. At the same time, through the above description, the cleaning of the lower mold in the cleaning area will not take up additional production time, thereby greatly improving the production efficiency; further, the rubber molding machine is fully automatic, which greatly reduces the occurrence of work-related injuries, thereby improving the safety of production.

[0047] In the present invention, the specific structure of the lower mold cleaning mechanism 11 can be selected within a wide range, but in order to further facilitate the cleaning of the lower mold, preferably, the lower mold cleaning mechanism 11 includes a fixed frame 18, a first ventilation pipe 16 is arranged on the fixed frame 18, and the first ventilation pipe 16 is connected to at least one first blowing port 17 for blowing air downwards, so as to be able to blow air to the top of the lower mold; the fixed frame 18 is arranged in the middle of the side walls on both sides of the first cleaning area 5 and the second cleaning area 6; the fixed frame 18 can reciprocate horizontally in the first cleaning area 5 or the second cleaning area 6. Therefore, as long as the lower mold is transported to the cleaning area (the first cleaning area or the second cleaning area) through the conveying mechanism, the fixed frame 18 drives the first ventilation pipe 16 to reciprocate in the cleaning area, so that the first blowing port 17 blows air to the lower mold, and the high-pressure air connected to the first ventilation pipe 16 can blow away the scraps on the lower mold, thereby achieving the cleaning of the lower mold; and the reciprocating motion can greatly improve the cleaning efficiency and effect.

[0048] In the present invention, the specific structures of the first material picking mechanism 9 and the second material picking mechanism 8 can be selected within a wide range, but in order to further improve the efficiency of material picking, preferably, the first material picking mechanism 9 and the second material picking mechanism 8 both include a base 12, at least one chuck 15 is arranged below the base 12, and a base driving unit 13 and a chuck driving unit 14 are respectively arranged on the base 12; the base 12 is arranged at the top of the first material picking area or the second material picking area, the base driving unit 13 can drive the base 12 to reciprocate in the horizontal direction, and the chuck driving unit 14 can drive the chuck 15 to open and close.
