[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this utility model or its application or use. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] To further understand the content of this utility model, the technical solution will be further described below in conjunction with specific embodiments.

[0025] Example 1: As Figs. 1-4 As shown, this embodiment provides a special pressing fixture for fabric-reinforced plastic bowls, which solves the problem of fabric wrinkling and deformation that occurs during the vulcanization molding of fabric-reinforced plastic bowls. Specifically, it includes an upper plate 1, a lower plate 2, and a pressing ring 3. The lower surface of the upper plate 1 is machined with a groove 10 that matches the fabric-reinforced plastic bowl product, and the upper surface of the lower plate 2 is machined with a protrusion 20 that matches the groove 10. When the fabric 4 is placed on the lower plate 2 and the upper plate 1 is pressed onto the lower plate 2, the protrusion 20 extends into the groove 10, and the protrusion 20 and the groove 10 cooperate to fix the fabric 4 and press out the shape of the fabric-reinforced plastic bowl. Furthermore, the upper surface of the lower plate 2 is also provided with a receiving groove 21, located outside the protrusion 20, and the pressing ring 3 is located within the receiving groove 21.

[0026] As a specific implementation of this embodiment, the inner wall of the receiving groove 21 near the protrusion 20 is inclined toward the direction of the protrusion cavity, and the inner side of the pressing ring 3 has a slope and the same inclination angle and inclination direction as the inner wall of the receiving groove 21. That is to say, the inner side of the pressing ring 3 is in contact with the inner wall of the receiving groove 21 near the protrusion 20. The inclined surface of the receiving groove 21 in the direction of the protrusion cavity can better realize the function of stretching or pressing the cloth, and also play a role in positioning the pressing ring 3.

[0027] To facilitate the removal of the pressure ring 3, the pressure ring 3 has four screw holes 30, which are through holes. The lower plate 2 has four lifting grooves 22, the bottom of which is lower than the bottom of the receiving groove 21. The screw holes 30 are positioned corresponding to the lifting grooves 22, and are located above the lifting grooves 22. When the pressure ring 3 is difficult to remove, a workpiece with a hook can be passed through the screw hole 30, and the lifting groove 22 will make way, allowing the pressure ring 3 to be easily hooked out. Alternatively, a screw can be passed through the screw hole 30, with the screw pressing against the bottom of the lifting groove 22, and the pressure ring 3 can be slowly lifted by rotating the screw; or the screw can be screwed into the screw hole 30, and the pressure ring 3 can be pulled up by pulling the screw.

[0028] In order to carry out the mold work, the upper plate 1 and the lower plate 2 are provided with screw holes 5 connected with the vulcanization equipment to drive the upper plate 1 and the lower plate 2 to move.

[0029] In the embodiment, the upper plate 1 is provided with four positioning holes 11, and the lower plate 2 is provided with positioning pins 23 which are inserted into the positioning holes 11 to guide and position the upper plate 1 and the lower plate 2, so as to ensure that the upper plate 1 and the lower plate 2 are perfectly matched.

[0030] The utility model discloses simple structure, practical, through the cooperation of convex block 20 and recess 10, effectively fixed cloth clamp 4 and will cloth clamp 4 press out the shape of required product, on this basis, introduce cloth ring 3 and the accommodation groove 21 cooperation and both bevel inclination angle and direction same, realize cloth and press cloth's function, solved the cloth clamp 4 wrinkle problem when appearing in the vulcanization forming of cloth clamp rubber bowl, improved product yield, improved production efficiency.

[0031] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the utility model, and not to limit them; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it still can modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
