Description

Technical Field

[0001] The invention relates to the technical field of insulator production equipment, and in particular to a vulcanization molding machine for an upper cylinder type support composite insulator. Background Art

[0002] Insulators are widely used in power systems. They are installed between conductors of different potentials or between conductors and grounded components. Their main function is to withstand voltage and mechanical stress to ensure the normal operation of the power system. Insulators include porcelain insulators, glass insulators, composite insulators, etc. Among them, composite insulators are preferred in related technologies due to their small size, light weight, high tensile strength, and excellent anti-pollution flashover performance.

[0003] The production process of composite insulators mainly includes processes such as mud preparation, forming, drying, firing and assembly. In the forming stage, a vulcanization molding machine is usually used to vulcanize the insulators.

[0004] A Chinese patent application document with application publication number CN116994841A discloses an insulator vulcanization molding equipment, which includes a clay feeding part, a hot pressing forming part and a loading and unloading transmission part. The hot pressing forming part includes an upper mold, a lower mold and a power mechanism for driving the two to separate the molds. A heating mechanism is integrated in the upper and lower molds. The loading and unloading transmission part includes two groups of support brackets distributed on both sides of the hot pressing forming part. The support brackets can slide horizontally and longitudinally, and can be lifted and lowered in the vertical direction. The clay feeding part is arranged at the upper side of the upstream end of the hot pressing forming part.

[0005] The above patent application adopts an automatic loading and unloading design to realize automatic laying of glue, automatic arrangement of core rods and automatic unloading, without the need for manual access to the mold, which improves efficiency and reduces the risk of burns. However, during the vulcanization process of the insulator, a layer of excess skirt will be generated on both sides. In the related technology, the skirt is usually torn off manually, which is time-consuming and labor-intensive, affecting production efficiency. In addition, the temperature of the insulator just after vulcanization is high, which is easy to burn the staff. Summary of the invention

[0035] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0036] like Figures 1 to 8 As shown, the upper cylinder type support composite insulator vulcanization molding machine of the present invention comprises: a base 1 and a lifting seat 2.

[0037] Specifically, Figure 1 and Figure 2 As shown, a lower mold 4 is provided on the base 1, and a heating device, a temperature sensor and a control board are provided inside the base 1. The heating device is an electric heater in conventional technology, and the temperature sensor is an electronic thermometer in conventional technology, which is electrically connected to the control board, and the control board is electrically connected to the heating device. The temperature sensor is used to detect the temperature of the insulator during vulcanization molding, and convert the temperature data into an electrical signal and transmit it to the control board. When the temperature of the insulator is lower than the set temperature, the control board starts the heating device, and when the temperature of the insulator reaches the set temperature, the control board turns off the heating device. The lifting seat 2 is located above the base 1, and the lifting seat 2 is provided with a hydraulic cylinder, which is used to drive the lifting seat 2 to move up and down, and the bottom of the lifting seat 2 is provided with an upper mold 3.

[0038] like Figures 2 to 4As shown, the lower mold 4 is slidably fitted on the base 1, and the lower mold 4 is elastically connected to the base 1 through a second elastic member, and the second elastic member is a spring. The lower mold 4 can move up and down, and a scraper 5 is also provided on the lower mold 4. There are two scrapers 5, and they are symmetrically distributed on both sides of the lower mold 4. Each scraper 5 is provided with a matching groove with the same contour as the insulator, and the side wall of the matching groove can fit with the insulator. The scraper 5 is connected to the base 1 through a first elastic member, and the first elastic member is a spring. The scraper 5 can move up and down, and a plurality of guide columns 10 are provided on the base 1. The guide column 10 is a telescopic structure. The first elastic member and the second elastic member are both located in the corresponding guide column 10, and the guide column 10 is used to prevent the lower mold 4 and the scraper 5 from deflecting when moving up and down.

[0039] like Figure 2 , Figures 5 to 7 As shown, the scraper 5 is provided with a limit seat 6, and the limit seat 6 is provided with a first limit groove 61, and the lower die 4 is provided with a first limit rod 7, which is horizontally distributed, and the first limit rod 7 is slidably matched with the lower die 4 and can extend out of the lower die 4, and the first limit rod 7 is elastically connected to the lower die 4 through a first elastic member, and the first elastic member is a spring. A limit block 71 is provided at the end of the first limit rod 7, and the limit block 71 can extend into the first limit groove 61 and be engaged with the limit seat 6, so as to realize the engagement between the scraper 5 and the lower die 4, and the lower die 4 is slidably matched on the base 1, and the scraper 5 and the lower die 4 can move up and down synchronously. The limiting seat 6 is also provided with a first inclined surface block 62 and a second inclined surface block 63. The first inclined surface block 62 is located at the bottom of the limiting seat 6, and the second inclined surface block 63 is located below the first limiting groove 61. The first inclined surface block 62 and the second inclined surface block 63 can both stop against the first limiting rod 7, thereby pushing the first limiting rod 7 to move and gradually retract into the lower mold 4. A second limiting rod 9 is also provided on the base 1. The second limiting rod 9 is vertically distributed. A second limiting groove 91 is provided on the second limiting rod 9. A groove 72 is provided on the first limiting rod 7. The side wall of the groove 72 can stop against the side wall of the second limiting rod 9. When the first limiting rod 7 moves until the groove 72 is flush with the second limiting groove 91, the groove 72 is out of contact with the side wall of the second limiting groove 91. The first limiting rod 7 can extend out of the lower mold 4 under the push of the third elastic member 8, and the first limiting rod 7 extends into the second limiting groove 91, so that the second limiting rod 9 is engaged with the first limiting rod 7, thereby preventing the lower mold 4 from moving up and down.

[0040] Under the pressure of the upper mold 3 and the lifting seat 2, the bottom end of the lower mold 4 is tightly attached to the base 1, and the scraper 5 is tightly attached to the lower mold 4. At this time, the limit block 71 is located in the first limit groove 61, the scraper 5 is clamped with the lower mold 4, and the first elastic member and the second elastic member are both contracted. When the lifting seat 2 moves upward, the first elastic member and the second elastic member stretch and release the elastic force, and the first elastic member pushes the scraper 5 and the lower mold 4 to move upward synchronously. During this process, the first limiting rod 7 moves upward along the second limiting rod 9. When the groove 72 is flush with the second limiting groove 91, the first limiting rod 7 extends into the second limiting groove 91 under the push of the third elastic member 8, thereby engaging with the second limiting rod 9. The second limiting rod 9 prevents the lower mold 4 from moving upward. At the same time, the limiting block 71 extends out of the first limiting groove 61, thereby releasing the engagement between the scraper 5 and the lower mold 4. The scraper 5 continues to move upward under the elastic force of the first elastic member, and the lower mold 4 remains stationary due to the restriction of the second limiting rod 9. As the scraper 5 continues to move upward, the first inclined surface block 62 gradually approaches the first limiting rod 7 and engages with the second limiting rod 9. The first limiting rod 7 contacts, and the first inclined surface block 62 pushes the first limiting rod 7 into the lower mold 4, so that the groove 72 is aligned with the second limiting groove 91, and the second limiting rod 9 releases the clamping connection with the first limiting rod 7. At this time, the elastic force of the first elastic member and the gravity of the scraper 5 are in a horizontal state, and the scraper 5 remains stationary. The lower mold 4 moves upward under the action of the second elastic member, and the first limiting rod 7 moves upward relative to the limiting seat 6 and gradually approaches the second inclined surface block 63. When the first limiting rod 7 contacts the second limiting rod 9, the height of the first limiting rod 7 is higher than the top end of the second limiting rod 9. When the first limiting rod 7 passes over the second inclined surface block 63, the limiting block 71 on the first limiting rod 7 re-extends into the first limiting groove 61. At this time, the first limiting rod 7 is clamped with the limiting seat 6, and the lower mold 4 is fitted with the scraper 5.

[0041] like Figure 2 and Figure 8As shown, a cleaning mechanism 11 is also provided on the base 1, and the cleaning mechanism 11 includes a mounting frame 111, a driving member 112 and a cleaning rod 114. The mounting frame 111 is slidably fitted on the base 1, and the driving member 112 is a motor, which is fixedly connected to the base 1. A driving gear 113 is provided at the output end of the driving member 112, and a driving tooth groove is provided on the mounting frame 111, which meshes with the driving gear 113. The driving member 112 can drive the mounting frame 111 to approach or move away from the scraper 5. The cleaning rod 114 is slidably fitted on the mounting frame 111 and can move up and down relative to the mounting frame 111. The driving mechanism includes a blocking rod 117 and a fourth elastic member 115. The fourth elastic member 115 is a spring, and its two ends are respectively fixedly connected to the mounting frame 111 and the cleaning rod 114. The blocking rod 117 is fixedly connected to the base 1, and has a first end and a second end. The first end of the blocking rod 117 has an upward inclined surface, and the second end of the blocking rod 117 has a downward inclined surface. The bottom end of the cleaning rod 114 is provided with a slider 116, which can stop with the blocking rod 117 and slide along the blocking rod 117.

[0042] When the driving member 112 drives the mounting frame 111 to move inward and approach the scraper 5 through the driving gear 113, the sliding block 116 gradually approaches the blocking rod 117 and stops at the first end of the blocking rod 117. The sliding block 116 moves along the inclined surface of the first end to above the blocking rod 117, thereby causing the cleaning rod 114 to move upward. At this time, the fourth elastic member 115 is compressed, and there is a gap between the cleaning rod 114 and the scraper 5. When the mounting frame 111 continues to move to the inner side of the scraper 5, the sliding block 116 disengages from the blocking rod 117, and the fourth elastic member 115 releases the elastic force, thereby pushing the cleaning rod 114 to move downward until the sliding block 116 is at the same height as the blocking rod 117. At this time, the driving member 112 drives the mounting frame 111 to move outward through the driving gear 113, and the sliding block 116 gradually approaches the blocking rod 117 and stops at the second end of the blocking rod 117. The sliding block 116 moves downward along the inclined surface of the second end, so that the cleaning rod 114 moves downward, and the fourth elastic member 115 is stretched. At this time, the bottom end of the cleaning rod 114 stops and slides with the scraper 5. In the process of the mounting frame 111 moving outward, the cleaning rod 114 can push the cut skirt on the scraper 5 to move outward and push the cut skirt away from the scraper 5 to ensure the cleanliness of the scraper 5.

[0043] According to the upper cylinder type support composite insulator vulcanization molding machine of the embodiment of the present invention, the insulator to be vulcanized is placed in the lower mold 4, at which time the scraper 5 is fitted with the lower mold 4, and then the lifting seat 2 moves downward. During the process, the upper mold 3 gradually approaches the scraper 5 and stops with the scraper 5, and pushes the scraper 5 and the lower mold 4 to move downward, the first elastic member and the second elastic member shrink until the lower mold 4 is fitted with the base 1, the heating device is started, and the insulator is vulcanized. After the vulcanization molding is completed, the lifting seat 2 moves upward, the first elastic member and the second elastic member release the elastic force and stretch, which push the lower mold 4 and the scraper 5 to move upward synchronously, the lower mold 4 is separated from the base 1, and the bottom of the lower mold 4 is exposed to the air, which accelerates the cooling of the insulator. When the first limiting rod 7 extends into the second limiting groove 91, the lower mold 4 remains stationary, the insulator is located in the lower mold 4, and the skirt on the side of the insulator is located on the scraper 5. At this time, the scraper 5 continues to move upward, thereby cutting off the skirt on the side of the insulator. When the scraper 5 moves to the uppermost end, the first inclined block 62 gradually approaches the first limiting rod 7 and contacts the first limiting rod 7. The first inclined block 62 pushes the first limiting rod 7 into the lower mold 4. The lower mold 4 moves upward under the push of the second elastic member and finally fits with the scraper 5. At this time, the insulator is taken out. After the insulator is taken out, the skirt cut off on the scraper 5 is removed by the cleaning mechanism 11.
