Description

Technical Field

[0001] The invention relates to the technical field of casting and forming, and in particular to a device and method for casting and forming electric power fittings. Background Art

[0002] Power fitting casting molding devices are equipment used to manufacture power fittings such as power towers, conductor clamps, joints, etc. These devices are usually used to melt metal and then cast it into shape to produce high-strength and durable power equipment components.

[0003] In the casting process of electrical fittings, the surface treatment of the mold is crucial. In order to ensure that the casting can be smoothly separated from the mold, the workers will evenly spray a layer of release agent inside the mold. This release agent is like a "protective film" for the mold. It can effectively prevent the molten metal from sticking to the mold during the casting process, thereby ensuring that the casting can be smoothly removed. When spraying, the workers carefully cover every corner of the mold with the release agent evenly to ensure that there is no missing place. After coating, they let the release agent dry naturally to form a thin protective layer. This not only improves the surface quality of the casting, but also reduces the wear of the mold, ensuring the smooth progress of production.

[0004] In most processes of spraying mold release agents, operators are required to hold a spray gun to spray the inside of the mold. The spraying effect of the handheld spray gun depends on the operator's skills and stability. Therefore, spray gun operation requires certain skills and experience. If the operation is improper, it may cause uneven spraying, inconsistent coating thickness, dripping or sagging, affecting the quality of the final product. Moreover, during the spraying process of the mold release agent, the mold release agent usually contains chemical components, and the mist generated by the spraying may pose a threat to the health of the operator. Therefore, it does not meet the existing needs. In this regard, we propose an electric hardware casting molding device and method. Summary of the invention

[0020] The present invention has the following beneficial effects:

[0021] 1.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1: This embodiment is intended to promote the solution of most processes of spraying mold release agents on molds. Operators are required to hold a spray gun to spray inside the mold. The spraying effect of the handheld spray gun depends on the operator's skills and stability. Therefore, spray gun operation requires certain skills and experience. If the operation is improper, it may cause uneven spraying, inconsistent coating thickness, dripping or sagging, affecting the quality of the final product. In addition, during the spraying of mold release agents, the mold release agent usually contains chemical components, and the mist generated by the spraying may pose a threat to the health of the operator. Please refer to Figure 1 - Fig.11 A device and method for casting electric hardware includes an operating platform 110 and a clamping seat 111 installed on the upper side of the operating platform 110 for clamping a mold. A spray gun 114 for spraying a release agent on the mold is installed on the upper side of the operating platform 110.

[0038] In this embodiment, the spray gun 114 is used to spray the release agent onto the mold surface. The spray gun 114 usually uses gas such as compressed air as a power source. There is a gas channel inside the spray gun 114. When the gas passes through the nozzle of the spray gun 114, a high-speed airflow is generated. This airflow pushes the release agent out of the nozzle and atomizes it into fine droplets to form a spray effect. Its specific model, working principle and usage are well known to those skilled in the art and will not be elaborated here.

[0039] The clamping seat 111 includes a first clamping block 112 and a second clamping block 113. A first support column 120 is installed on the upper side of the operating platform 110, and a second support column 121 is movably installed on the upper side of the operating platform 110. The first clamping block 112 is rotatably set on the side of the first support column 120, and the second clamping block 113 is rotatably set on the side of the second support column 121. A support plate 122 is installed on the upper side of the operating platform 110, and a driving motor 123 for controlling the movement of the clamping seat 111 is installed on the side of the support plate 122. A swing rod 130 for driving the clamping seat 111 to swing is installed on the side of the first support column 120.

[0040] See Figure 1A three-axis electric slide 124 for controlling the movement of the spray gun 114 is installed on the upper side of the operating platform 110. The three-axis electric slide 124 is an existing device for moving the spray gun 114. Its specific model, working principle and usage are well known to those skilled in the art, and they will not be elaborated here. A sliding groove 131 is opened on the upper side of the operating platform 110, and an electric slider 132 is installed on the bottom side of the second support column 121. The electric slider 132 is used to move the second support column 121 in this embodiment. The self-movement of the electric slider 132 first depends on its built-in motor. The motor serves as a power source and converts electrical energy into mechanical energy to provide the required power for the movement of the slider. The electric slider 132 is a prior art. Its specific model, working principle and usage are well known to those skilled in the art, and they will not be elaborated here. The electric slider 132 slides with the sliding groove 131.

[0041] See Figure 1 In this embodiment, the first clamping block 112 and the second clamping block 113 are used to clamp the mold to fix the position of the mold. The first clamping block 112 and the second clamping block 113 are set as pneumatic clamps in this embodiment. The pneumatic clamp uses compressed air to drive the cylinder, and the piston movement of the cylinder is used to open and close the clamping components such as claws to achieve clamping and fixation of the workpiece. The compressed air enters one side of the cylinder and pushes the piston to move, thereby driving the clamp to clamp or release the mold. The setting of the first clamping block 112 and the second clamping block 113 can clamp both sides of the mold. At the same time, the first clamping block 112 and the second clamping block 113 can also be set as suction cups, hydraulic clamps, etc. Since the pneumatic clamp is a prior art, its specific model, working principle and usage are well known to those skilled in the art, and will not be elaborated here.

[0042] See Figure 1 In the specific implementation, the operator uses the cooperation of the first clamping block 112 and the second clamping block 113 to make the mold located on the upper side of the operating platform 110. At the same time, the spray gun 114 uses the cooperation of the three-axis electric slide 124 to move to the top of the mold and spray the release agent into the mold, thereby realizing the automatic spraying of the release agent on the mold. Not only that, it reduces the contact between the operator and the chemicals and improves the operating safety.

[0043] This solution also proposes an optional method for casting electric hardware, which includes the following steps:

[0044] S1. The raw materials of the electrical fittings are melted and put into the existing melting furnace for melting treatment;

[0045] S2. In the process of melting the raw materials of the electrical fittings, a release agent is sprayed inside the mold using a spray gun 114;

[0046] S3. Casting the molten raw materials of the electrical fittings into the mold;

[0047] S4. After the raw material melt of the electrical hardware is cooled and formed inside the mold, the mold and the electrical hardware are demolded.

[0048] In this embodiment: the mold is clamped on the upper side of the operating platform 110 by utilizing the cooperation of the first clamping block 112 and the second clamping block 113, and then the spray gun 114 is moved to the upper side of the mold by utilizing the three-axis electric slide 124, and the release agent is sprayed into the inside of the mold. The first clamping block 112 and the second clamping block 113 cooperate with the three-axis electric slide 124 to automatically spray the release agent on the mold. Through automated spraying, the operator's contact with chemicals is reduced, thereby reducing the risk of inhaling harmful gases and chemicals and improving operational safety.

[0049] Embodiment 2: This embodiment is intended to solve the problem that in the process of spraying the mold release agent on the mold surface with the spray gun 114, the mold release agent may gather at the bottom of the mold due to its certain fluidity, resulting in uneven texture or defects on the bottom surface of the casting. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1 - Fig.11 A rotating rod 140 is rotatably installed on the side of the support plate 122, and the end of the rotating rod 140 is rotatably matched with the first support column 120. A pulley group 141 for transmission is installed between the rotating rod 140 and the output end of the driving motor 123. A first gear 142 is rotatably installed on the side of the first support column 120. A second gear 143 is coaxially installed on the surface of the rotating rod 140, and the second gear 143 is meshed with the first gear 142. A connecting rod 144 is coaxially installed on the side of the first gear 142, and a rotating disk 145 is installed on the end of the connecting rod 144.

[0050] The pulley assembly 141 drives the belt to rotate through the driving wheel, thereby transmitting power to the driven wheel. The power transmission in the mechanical system is realized through the cooperation of the pulley and the belt. In this embodiment, the pulley assembly 141 is used to drive the transmission between the motor 123 and the rotating rod 140.

[0051] See Figure 1 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 The swing rod 130 is rotatably mounted on the side of the first support column 120, a swing block 150 is coaxially mounted on the surface of the swing rod 130, a vertical groove 151 is opened inside the swing block 150, a connecting column 152 is eccentrically mounted on the side of the rotating disk 145, the connecting column 152 is slidably matched with the vertical groove 151, and the first clamping block 112 is mounted on the end of the swing rod.

[0052] See Figure 1 , Figure 6 , Figure 5 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 In a specific implementation, when the driving motor 123 is started, the rotating rod 140 is rotated by the transmission of the pulley set 141. Since the end of the rotating rod 140 is rotatably mounted on the side of the first supporting column 120, the first gear 142 and the second gear 143 are used to drive the rotating rod 140 to rotate while the first gear 142 is rotated. By coaxially arranging the rotating disk 145 on the side of the first gear 142, the rotating disk 145 is rotated by the transmission of the first gear 142 when the second gear 143 is rotating.

[0053] By eccentrically installing the connecting column 152 on the side of the rotating disk 145 and sliding the connecting column 152 inside the vertical slot 151, the connecting column 152 cooperates with the vertical slot 151 in the moving state to make the rocking block 150 swing back and forth. At the same time, the rocking block 150 is coaxially arranged with the rocking rod 130, so the rocking rod 130 swings following the rocking block 150. Since the first clamping block 112 is installed at the end of the rocking rod, the first clamping block 112 will swing following the rocking block 150. Therefore, the mold clamped on the first clamping block 112 will swing following the first clamping block 112, so that the release agent gathered at the bottom flows to the inner wall of the mold as the mold swings, thereby reducing the possibility of too much release agent gathering at the bottom of the mold, further enhancing the uniformity of the sprayed release agent, and at the same time helping to reduce surface flaws and defects of the casting.

[0054] In this embodiment: the rotation of the rotating rod 140 is achieved by the transmission between the driving motor 123, the pulley group 141 and the rotating rod 140, and the rotating rod 140 uses the transmission of the first gear 142 and the second gear 143 to rotate the rotating disk 145, and the connecting column 152 and the vertical groove 151 are used to drive the swing block 150 to swing when the rotating disk 145 rotates. During the swinging of the swing block 150, its coaxially installed swing rod 130 follows the swing block 150 to swing. Since the first clamping block 112 is installed at the end of the swing rod 130, the first clamping block 112 follows the swinging of the swing block 150. Therefore, the mold clamped on the first clamping block 112 will follow the swing, so that the release agent gathered at the bottom flows to the inner wall of the mold as the mold swings, reducing the possibility of excessive release agent gathering at the bottom of the mold, further enhancing the uniformity of the sprayed release agent, and at the same time helping to reduce surface flaws and defects of the casting.

[0055] Embodiment 3: This embodiment aims to promote the solution of the problem that the release agent gathered on the bottom side of the mold can flow to the inner wall of the mold during the swinging process through the cooperation between the swing block and the swing rod. However, a single swing can only achieve uniform spraying of the release agent on the front and rear inner walls of the mold, resulting in less release agent on both sides of the mold. This embodiment is an improvement made on the basis of Embodiment 2. For details, please refer to Figure 1 - Fig.11 A rotating cylinder 160 is installed at the end of the driving motor 123, a disc 161 is installed at the end of the rotating cylinder 160, a support frame 162 is installed on the side of the support plate 122, a first extending rod 170 is movably installed on the inner wall of the support frame 162, a movable rod 171 is rotatably installed inside the support frame 162, a first sliding column 172 is installed on the side of the first extending rod 170, a connecting rod 173 is coaxially installed on the end of the movable rod 171, and a second sliding column 174 is installed on the end of the connecting rod 173.

[0056] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig.11 A first track groove 180 is provided on the surface of the rotating cylinder 160, a second track groove 181 is provided on the side of the disc 161, the first sliding column 172 is slidably matched with the first track groove 180, the second sliding column 174 is slidably matched with the second track groove 181, a second extension rod 182 is installed inside the movable rod 171, a connecting plate 230 is installed at the end of the first extension rod 170, the connecting plate 230 is rotatably matched with the second extension rod 182, an air outlet plate 183 is installed at the end of the second extension rod 182, an air outlet pipe 184 is installed on the bottom side of the air outlet plate 183, a plurality of convex strips 185 are provided on the surface of the movable rod 171, and the plurality of convex strips 185 are installed on the surface of the movable rod 171 in a circular array, a plurality of slide grooves 190 are provided on the surface of the second extension rod 182, and the convex strips 185 are slidably matched with the slide grooves 190.

[0057] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig.11During the specific implementation, by starting the driving motor 123, the driving motor 123 drives the rotating cylinder 160 and the rotating disk 145 to rotate in the same direction. During the rotation, the first extending rod 170 slides to the front end of the first track groove 180 by the first sliding column 172, and the first extending rod 170 extends. At the same time, the first extending rod 170 drives the second extending rod 182 to extend from the inside of the movable rod 171 through the connecting plate 230, so that the air outlet plate 183 installed at the end of the second extending rod 182 is located on the upper side of the mold. At the same time, the second sliding column 174 installed at the end of the movable rod 171 cooperates with the second track groove 181. When the second sliding column 174 slides to the inflection point of the second track groove 181, the movable rod 171 swings by the cooperation of the connecting plate 230 and the second sliding column 174, so that the air outlet plate 183 swings to the upper side of the mold.

[0058] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Fig.11 An air storage tank 210 is provided inside the first support column 120, a piston plate 211 is installed at the end of the swing rod 130, and the end of the piston plate 211 is rotatably matched with the air storage tank 210. A one-way valve 212 is symmetrically installed on the side of the first support column 120, and the one-way valve 212 is communicated with the inside of the air storage tank 210. A connecting pipe 220 is symmetrically installed on the side of the first support column 120, and two connecting pipes 220 are communicated with the inside of the air storage tank 210. A delivery pipe 221 is connected to the side of the connecting pipe 220, and the delivery pipe 221 is connected to the air outlet plate 183. A check valve is installed at the connection between the connecting pipe 220 and the air storage tank 210 to minimize gas reflux.

[0059] A check valve is a common valve body and a device used to prevent the backflow of gas or liquid. It is widely used in pipeline systems. The check valve is a common technical means, so it will not be described in detail in this implementation.

[0060] In specific implementation, when the swing arm 130 rotates, the piston plate 211 installed at the end of the swing arm 130 will push the gas inside the gas storage tank 210 during the swinging process, so that the gas reaches the inside of the air outlet plate 183 through the delivery pipe 221 and the connecting pipe 220, and blows the release agent on the bottom surface of the mold through the air outlet pipe 184. At the same time, the release agent on the bottom side of the mold is blown to both sides by the cooperation of the air outlet plate 183, the rotating cylinder 160 and the disc 161, so that the release agent is attached to the inner wall of the mold by the blowing of the gas, thereby further realizing the uniformity of the spraying of the release agent.

[0061] It should be noted that during the rotation of the piston plate 211, the piston plate 211 will reciprocate inside the air storage tank 210, so two cavities are formed inside the air storage tank 210 with the piston plate 211 as the boundary. During the movement of the piston plate 211, the piston plate 211 will squeeze the gas contained in one of the cavities, and the gas will flow out through the connecting pipe 220. At the same time, during the movement of the piston plate 211, a negative pressure is formed in the other cavity. When the negative pressure is formed, the one-way valve 212 is used to communicate with the outside world, and the outside air is absorbed to achieve automatic air supply.

[0062] In this embodiment: through the cooperation of the swing rod 130, the piston plate 211 and the gas storage tank 210, the swing rod 130 pushes the gas inside the gas storage tank 210 during the swinging process, so that the gas reaches the inside of the gas outlet plate 183 through the delivery pipe 221 and the connecting pipe 220, and blows the release agent on the bottom surface of the mold through the gas outlet pipe 184; at the same time, the driving motor 123 drives the rotating cylinder 160 and the rotating disk 145 to rotate in the same direction, and the first extension rod 170 uses the cooperation of the first sliding column 172 installed on its side and the first track groove 180 to realize the action of extending the first extension rod 170, and at the same time, the first extension rod 170 The rod 170 drives the second extending rod 182 to extend out from the inside of the movable rod 171 through the connecting plate 230, so that the air outlet plate 183 installed at the end of the second extending rod 182 is located on the upper side of the mold. At this time, the second sliding column 174 installed at the end of the movable rod 171 cooperates with the second track groove 181, so that the air outlet plate 183 can blow air to the mold surface while swinging, which not only realizes the blowing of the gas to the release agent on the bottom side of the mold, but also allows the gas to blow to both sides of the bottom side of the mold at the same time, further blowing the release agent gathered at the bottom to both sides, further improving the uniformity of spraying the release agent, and improving the forming effect of the electrical hardware.
