DETAILED DESCRIPTION

[0022] As shown in Figure 1 , Figure 2 and Figure 4 , the production equipment of the power composite insulator of the embodiment includes a core disc 1, the upper surface of the core disc 1 is provided with an umbrella head 101, the upper surface of the umbrella head 101 is provided with a notch, the middle part of the inner arc surface of the core disc 1 close to the notch is provided with an elastic pressing surface 102, the lower surface edge of the elastic pressing surface 102 is provided with a protruding part 103, the umbrella head 101 and the elastic pressing surface 102 are provided with an embedded groove, the embedded groove between the umbrella head 101 and the elastic pressing surface 102 is sleeved with a pot-type upper die body 2, the upper surface of the pot-type upper die body 2 is provided with a folded edge 201, the upper surface of the folded edge 201 is placed on the top of the notch, the upper surface of the pot-type upper die body 2 is sleeved with an arched support plate 3, the outer arc surface of the bottom of the arched support plate 3 is provided with a skirt, the surface of one side skirt of the arched support plate 3 is provided with a threaded hole 301, and the arched support plate 3 is fixedly connected with the core disc 1 through the threaded hole 301 at the top of the skirt.

[0023] The core disc 1 is the core bearing and positioning component of the entire production equipment of the power composite insulator, and the overall structure thereof provides a stable assembly basis for each component. Through cooperation with the pot-type upper die body 2, the arched support plate 3, the pot-type lower die body 4 and other components, a closed space required for forming of the insulator is jointly constructed. In the forming process, the core disc 1 can bear the forming pressure, ensure the relative position stability of each component, provide reliable rigid support for the forming of the insulator, guide the gas discharge and assist demolding by virtue of the structural design thereof, and effectively guarantee the forming quality.

[0024] The notch of the umbrella-shaped head 101 on the upper surface of the core disk 1 provides a placement space for the folded edge 201 of the basin-shaped upper mold body 2, realizing the initial axial positioning of the basin-shaped upper mold body 2, and the umbrella-shaped head 101 cooperates with the elastic pressing surface 102 to form an embedding groove, which radially constrains the basin-shaped upper mold body 2 to prevent it from shifting horizontally during assembly and operation, laying a solid foundation for the subsequent fixation of the arch support plate 3, thereby ensuring the structural stability of the upper mold part. Among them, when the elastic pressing surface 102 is assembled, the protrusion 103 of the lower surface edge of the elastic pressing surface 102 is clamped with the positioning groove 501 of the basin-shaped insulator cavity 5, and the basin-shaped insulator cavity 5 is pressed upward by the pre-tightening force generated by its own elasticity, realizing the basin-shaped insulator cavity 5. The rim cavity 5 is initially fixed to the core disk 1, and the protrusion 103 is an arc-shaped structure, and the concave-convex matching structure formed by adapting to the positioning groove 501 can limit the horizontal displacement of the basin-shaped insulator cavity 5, ensuring that it is aligned with the molding pressure cavity 104 of the core disk 1, avoiding errors in the insulator molding size due to positioning deviations. At the same time, under the elastic action of the elastic pressing surface 102, the protrusion 103 fits tightly with the positioning groove 501, thereby enhancing the stability of the overall structure. During the molding process, when pressure changes occur inside the cavity, the elastic pressing surface 102 can produce moderate deformation to buffer pressure shocks and avoid damage to components due to rigid contact, while maintaining stable pressure on the basin-shaped insulator cavity 5.

[0025] The molding pressure cavity 104 at the bottom of the inner arc surface of the core disk 1 has a shape that matches the top structure of the insulator, and cooperates with the top of the basin-shaped insulator cavity 5 to form a complete insulator molding space. During the molding process, after the raw material is injected into the space, the molding pressure cavity 104 serves as the upper molding surface, and together with the basin-shaped insulator cavity 5, it limits the flow and molding shape of the raw material, ensuring that the insulator can be molded according to the designed size and structure. It fits with the basin-shaped lower mold body 4 on the lower surface, bearing the weight of the core disk 1 and the upper components. At the same time, the outer arc surface of the load-bearing edge 105 fits on the inner side wall of the concave surface of the basin-shaped lower mold body 4, forming radial positioning, which limits the relative rotation between the core disk 1 and the basin-shaped lower mold body 4. In addition, the lower surface of the load-bearing edge 105 abuts against the top of the sealing ring 6, compressing the sealing ring 6 to cause it to deform, thereby enhancing the sealing of the molding space and preventing raw material leakage and gas entry.

[0026] like Figure 3 and Figure 5 As shown, a forming pressure cavity 104 is provided at the bottom of the inner arc surface of the core disc 1 , and a bearing edge 105 is provided at the outer arc surface of the core disc 1 close to the forming pressure cavity 104 , and the lower surface of the bearing edge 105 is fittedly connected to the basin-shaped lower mold body 4 .

[0027] The basin-shaped upper mold body 2 is sleeved in the embedding groove between the umbrella-shaped head 101 and the elastic pressing surface 102, and is matched with the umbrella skirt structure of the upper part of the insulator, and is used as a forming mold of the upper part of the insulator. The preliminary positioning is realized by the cooperation of the folding edge 201 and the gap of the umbrella-shaped head 101. The basin-shaped upper mold body 2 is tightly attached to the core disc 1 under the fixing action of the arched supporting plate 3, and a stable upper mold forming structure is formed. The folding edge 201 is located on the upper surface of the basin-shaped upper mold body 2 and is placed on the top of the gap of the umbrella-shaped head 101. On the one hand, the folding edge 201 provides axial support for the basin-shaped upper mold body 2 and determines the installation height of the basin-shaped upper mold body 2 on the core disc 1. On the other hand, the cooperation with the gap limits the horizontal displacement of the basin-shaped upper mold body 2, preventing it from deviating during work. At the same time, the folding edge 201 is clamped between the umbrella-shaped head 101 and the arched supporting plate 3, which enhances the installation stability of the basin-shaped upper mold body 2. During the forming process, the basin-shaped upper mold body 2 bears the pressure of the raw material, ensuring the forming precision of the umbrella skirt structure of the upper part of the insulator, and cooperating with other parts to form a closed forming space.

[0028] The arched supporting plate 3 is sleeved on the top of the upper surface of the basin-shaped upper mold body 2 and is fixedly connected with the core disc 1 through the threaded hole 301 of the skirt edge cooperating with the bolt. The arched structure can disperse the pressure generated during fixing, so that the basin-shaped upper mold body 2 is uniformly stressed, ensuring that the basin-shaped upper mold body 2 is tightly attached to the core disc 1, avoiding the leakage of raw materials caused by gaps. At the same time, the arched supporting plate 3 has an axial pressing effect on the basin-shaped upper mold body 2, preventing the basin-shaped upper mold body 2 from moving upward under the action of forming pressure, and ensuring the structural stability of the upper mold part. The threaded hole 301 is arranged on the surface of the skirt edge of the arched supporting plate 3, and cooperates with the bolt to realize the detachable connection of the arched supporting plate 3 and the core disc 1. By tightening the bolt, the axial pre-tightening force is generated by the self-locking property of the thread, so that the arched supporting plate 3, the basin-shaped upper mold body 2 and the core disc 1 are firmly connected together, ensuring that the parts will not be separated due to pressure during the forming process. The threaded connection facilitates the disassembly and maintenance of the equipment, and different specifications of the basin-shaped upper mold body 2 can be replaced according to production needs.

[0029] As Figure 6 and Figure 7As shown, the middle part of the upper surface of the basin-shaped insulator cavity 5 is provided with a positioning groove 501, the inner bottom wall of the positioning groove 501 is matched and clamped with the protruding part 103 of the lower surface of the elastic pressing surface 102, the middle part of the basin-shaped lower mold body 4 is provided with a lower concave surface, the basin-shaped insulator cavity 5 is placed in the lower concave surface of the basin-shaped lower mold body 4, the lower surface of the core disc 1 is placed on the top of the basin-shaped insulator cavity 5 and is in a vertical plane, the outer arc surface of the bearing edge 105 is attached to the inner side wall of the concave surface of the basin-shaped lower mold body 4, the lower surface of the bearing edge 105 abuts against the top of the sealing ring 6, the inner arc surface of the basin-shaped lower mold body 4 is provided with an annular air passage 402 near the sealing ring 6, one side of the annular air passage 402 near the lower concave surface is provided with an exhaust hole A7, the exhaust hole A7 is matched with the cavity in the basin-shaped lower mold body 4, the annular air passage 402 is provided with an air inlet hole B8 near the lower surface of the basin-shaped lower mold body 4, and the air inlet hole B8 is placed on the bottom surface of the basin-shaped insulator cavity 5.

[0030] The basin-shaped lower mold body 4 is designed as a whole in a basin shape to provide a mounting platform for the basin-shaped insulator cavity 5, the lower concave surface in the middle part is matched with the shape of the basin-shaped insulator cavity 5, which can ensure the stable position of the cavity during the molding process, and cooperates with the bearing edge 105 of the core disc 1 to form a closed molding environment, when the core disc 1 is pressed down, the pressure of the upper structure is supported by the bearing edge 105, and when the core disc 1 is lifted for demolding, the structure provides a channel for air to enter, and the demolding operation is completed in cooperation, the positioning hole 401 is arranged on the upper surface of the basin-shaped lower mold body 4 and is in the same vertical plane as the bearing edge 105, during assembly, the positioning pin passes through the positioning hole 401 and is inserted into the corresponding hole position of the bearing edge 105, so as to limit the relative displacement of the two in the horizontal direction, ensure that the molding cavity 104 of the core disc 1 is completely aligned with the top of the basin-shaped insulator cavity 5, avoid the size error of the insulator caused by assembly deviation, and enhance the structural stability of the equipment during stress process.

[0031] The basin-shaped insulator cavity 5 is a direct space for molding the insulator body, the inner wall shape is matched with the structure of the umbrella skirt and the core rod of the insulator, during the molding stage, cooperates with the molding cavity 104 of the core disc 1 to form a closed cavity to constrain the flow and solidification form of the raw material, the conical structure of the outer arc surface is attached to the lower concave surface of the basin-shaped lower mold body 4 to ensure that the cavity does not deform under pressure, in addition, the positioning groove 501 in the middle part of the upper surface of the cavity and the protruding part 103 of the lower surface of the elastic pressing surface 102 form a concave-convex cooperation, on the one hand, the cavity is limited in the horizontal direction by mechanical clamping to ensure that the cavity is accurately aligned with the molding cavity 104 of the core disc 1, on the other hand, under the elastic pre-tightening force of the elastic pressing surface 102, the groove is tightly attached to the protruding part 103 to enhance the stability of the cavity under the molding pressure and avoid the cavity from deviating due to vibration or pressure fluctuation.

[0032] The inner arc surface of the basin-shaped lower mold body 4 is provided with an annular air passage 402 near the sealing ring 6, which is a core passage for air pressure adjustment. The annular structure can ensure uniform circulation of air around the cavity. During the pressing process of the core disc 1, the air in the cavity flows into the annular air passage 402 through the exhaust hole A7, and then is discharged outside the equipment through a pre-set path, avoiding air bubbles caused by air residues. When the core disc 1 is lifted, external air enters the annular air passage 402 through the air inlet hole B8, and then is dispersed to the gap between the cavity and the insulator, providing uniform air pressure assistance for demolding. The annular design ensures the symmetry of air flow, preventing local air pressure imbalance from affecting molding or demolding effect.

[0033] The sealing ring 6 is arranged at the outer arc surface bottom of the basin-shaped insulator cavity 5 and is made of high-temperature-resistant elastic material. Based on elastic deformation, the sealing ring 6 realizes sealing. When the core disc 1 is pressed down, the lower surface of the bearing edge 105 abuts against the top of the sealing ring 6, forcing the sealing ring 6 to compress and deform, tightly filling the gap between the bearing edge 105 and the basin-shaped lower mold body 4, preventing leakage of molding raw materials or uncontrolled entry of external air into the cavity. During the demolding stage, the elastic reset of the sealing ring 6 can assist in restoring the sealing surface state, ensuring the sealing performance in the next molding, reducing the rigid friction between parts, and prolonging the service life of the equipment.

[0034] At the same time, the exhaust hole A7 connects the annular air passage 402 and the cavity of the basin-shaped lower mold body 4, and is a path for discharging internal air during the pressing process of the core disc 1. When the core disc 1 is pressed down, the air in the cavity is extruded and enters the annular air passage 402 through the exhaust hole A7, and is finally discharged outside the equipment, avoiding air bubbles caused by air residues affecting the insulation performance of the insulator. The diameter and distribution of the exhaust hole A7 are designed to control the exhaust speed, ensure that the air is completely discharged during the raw material filling process, and prevent the raw material from overflowing due to excessive exhaust speed.

[0035] The air inlet hole B8 is arranged at a position close to the lower surface of the basin-shaped lower mold body 4 in the annular air passage 402, and corresponds to the bottom surface of the basin-shaped insulator cavity 5. The air inlet hole B8 is used to introduce external air to assist demolding when the core disc 1 is lifted. When the core disc 1 moves upward, a negative pressure is formed in the cavity. Under the action of the pressure difference, external air enters the annular air passage 402 through the air inlet hole B8, and then diffuses to the gap between the cavity and the insulator through the exhaust hole A7, forming air pressure support and reducing the adhesion between the insulator and the inner wall of the cavity, making the demolding process smoother and reducing the risk of product damage caused by forced demolding, improving production efficiency.
