[0018] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0019] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] See also Figure 1-3 As shown, a new type of special rubber molding machine includes an upper mold 1, a lower mold 2 and an injection molding machine 3. Fixed blocks 5 are installed on both sides of the front and rear end surfaces of the injection molding machine 3, and guide rods 6 are provided in the holes above the four fixed blocks 5. The front and rear ends of the connecting bar seats 7 on both sides of the top of the upper mold 1 are respectively fixedly connected to the bottom ends of the corresponding guide rods 6. A bottom plate 13 is installed at the bottom of the lower mold 2, and a lifting and core supporting mechanism is provided in the rectangular groove 202 on the lower mold 2. The two sides of the bottom of the bottom plate 13 are respectively in rolling contact with the corresponding groups of supporting wheels 11. The rear end surface of the lower mold 2 is connected to the cylinder 3 19 located in the middle of the U-shaped plate 10, and the bottom of the U-shaped plate 10 is fixedly connected to the top of the supporting plate 9.

[0021] The core lifting and supporting mechanism includes a cylinder 12, a bar 204, a connecting plate 17 and a cylinder 2 18. One side of the bar 204 is fixedly connected to one end of a plurality of equally distributed core rods 203, and the other side of the bar 204 is connected to two cylinders 2 18 located on the connecting plate 17. The bottoms of both ends of the connecting plate 17 are connected to the cylinder 12 connected to the bottom of the lower mold 2.

[0022] Guide columns 16 are installed between the four corners of the bottom of the injection molding machine 3 and the four corners of the top of the base 15, and the guide columns 16 are in sliding contact with the corresponding guide holes 901 on the support plate 9. The bottom of the support plate 9 is connected to the cylinder 14 on the base 15, and an intelligent control cabinet 8 is provided on one side of the base 15. The cylinder 14 is extended and retracted to stably lift and lower the support plate 9 along the four guide columns 16 to separate the upper mold 1 from the lower mold 2.

[0023] The bottom of the bar 204 is in sliding contact with the bottom of the rectangular groove 202, and the core rod 203 located on one side of the bar 204 extends into the molding cavity 201 by movement; a protective plate 4 is provided between the top of the upper mold 1 and the bottom of the injection molding machine 3, and the four corners of the protective plate 4 are connected to the corresponding fixed block 5 through a connecting structure; there are two groups of supporting wheels 11, and multiple supporting wheels 11 in each group are equidistantly installed on the corresponding side walls in the U-shaped plate 10.

[0024] When the utility model is in use, the oil cylinder 14 stretches to move the lower mold 2 connected to the bottom plate 9 upward, so that the lower mold 2 and the upper mold 1 are sealed together, and the injection molding machine 3 injects the rubber melt into the special rubber molding mold. After a period of time after the injection is completed, the oil cylinder 14 contracts to separate the lower mold 2 connected to the bottom plate 9 from the upper mold 1, and the characteristic rubber molding is placed on the lower mold 2. After the lower mold 2 drops to the set position, the cylinder 19 stretches to move the connected lower mold 2 from the rear end to the front end of the U-shaped plate 10 under the support of the bottom of the tugboat 11, and then runs. The cylinder 12 is in an operating state of first slowly retracting and then continuously extending, so that the connecting plate 17, the second cylinder 18, the strip 204 and the core rod 203 connected thereto are raised, so that the special rubber molded part is separated from the lower mold 2. Since the core rod 203 is placed in the molded part and can be withdrawn, the operating cylinder 2 18 is in a contracted state and drives the strip 204. At the same time, the operator holds the outer end of the special rubber molded part and separates the core rod 203 connected thereto from the inside of the special molded part, completing the entire process of mold closing, injection molding, demoulding and removing the special rubber molded part.

[0025] To sum up: the guide column is used to guide the lifting of the connected lower mold and the guide rod is used to position the connected upper mold. At the same time, the oil cylinder used for lifting is used to greatly improve the stability and accuracy of the separation and combination of the upper and lower molds. The lower mold can be pushed outward, which is convenient for workers to implement necessary operating procedures. The core lifting and supporting mechanism is adopted to solve the problem of inconvenience in demolding molded parts in existing special rubber molding machines, and the function of automatic and stable demolding is realized, which saves time and effort, reduces unnecessary operating contact for workers, and has a high production safety factor.
