DETAILED DESCRIPTION

[0015] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the embodiment described below is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0017] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships 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.

[0018] See also Figure 1-3As shown, a convenient demoulding mold for special rubber products includes a lower mold 1 and an upper mold 3. The lower mold 1 is installed on the top surface of a download plate 2, and the download plate 2 is fixedly installed between two fixed plates 9. A cylinder 10 is installed in the middle of the two fixed plates 9, and the push rod end of the cylinder 10 is fixedly connected to the middle position of the bottom of a supporting plate 7. Two limiting grooves 701 are symmetrically provided on one side of the top of the supporting plate 7. The upper mold 3 is installed on the bottom surface of an upper loading plate 4, and two short columns 5 are symmetrically installed on both sides of the upper loading plate 4, and the short columns 5 are in sliding contact with the corresponding limiting grooves 701. The main columnar protrusion 401 located at the rear end of the upper loading plate 4 is in sliding contact with the engaging groove 601 located on the rear limiting block 6 through movement.

[0019] Furthermore, two ends of the supporting plate 7 are fixedly connected to one end of two guide rods 8 respectively.

[0020] Furthermore, two guide holes 901 are symmetrically formed on the fixing plate 9 , and the guide holes 901 are in sliding contact with the guide rods 8 .

[0021] Furthermore, the inner wall of the limiting groove 701 is a semi-cylindrical wall, and one end of the limiting groove 701 is connected to the side wall of the supporting plate 7 .

[0022] Furthermore, one side of the rear limit block 6 is fixedly connected to a corresponding portion on the external injection molding equipment.

[0023] When the utility model is in use, when the fixing chamber between the lower mold 1 and the upper mold 3 is released, since the short columns 5 on both sides of the upper loading plate 4 are in contact with the corresponding limiting grooves 701 on the supporting plate 7, the supporting plate 7 is pushed upward by the oil cylinder 10 extending upward, thereby driving the upper loading plate 4 and the upper mold 3 connected by the limiting grooves 701 and the short columns 5 to move upward, and complete the separation from the lower mold 1. In the process of continuous upward movement, the cylindrical protrusion 401 at the rear end of the upper loading plate 4 contacts the inside of the bite groove 601 on the rear limiting block 6, and at the same time, the short column 5 at the rear end becomes a fulcrum for side rotation, and the short column 5 at the front end is separated from the corresponding limiting groove 701, so that the upper loading plate 4 and the upper mold 3 are turned sideways upward, so as to expose the mold surface on the upper mold 3 laterally, which provides convenience for cleaning the mold surface;

[0024] In summary: the demoulding method of first splitting the mold and then turning the upper mold outward and sideways is adopted to achieve the function of convenient demoulding and solve the problem of inconvenient cleaning of the mold surface position of the upper mold.
