Description

Technical Field

[0001] The present invention relates to the technical field of plastic fitting casting equipment, and more specifically, to a fitting casting mold for machining. Background Art

[0002] A casting mold refers to forming the structural shape of a part in advance with other materials that are easier to form, and then placing the mold in a sand mold. Thus, a cavity with the same structural dimensions as the part is formed in the sand mold, and a fluid with fluidity is poured into the cavity. After the liquid cools and solidifies, a part with exactly the same shape and structure as the mold can be formed. The casting mold is an important part of the casting process. The progress of casting mold technology will provide more precise, complex, and high-quality castings for pillar industries such as automobiles, electricity, ships, rail transit, and aerospace.

[0003] Currently, the commonly used fitting casting molds for machining consist of a moving mold and a fixed mold. Most of the fixed mold remains stationary, so during demolding, it mainly relies on the action of the release agent and the ejector pins in the moving mold. Once the release agent is used unreasonably, the ejector pins need to exert greater force to separate the fitting from the mold, and it is easy for the fitting to be difficult to fall off. At the same time, plastic fittings are relatively brittle, and once the force borne by the plastic fitting is too large, it is extremely easy to break. Summary of the Invention

[0004] The purpose of the present invention is to provide a fitting casting mold for machining to solve the problems raised in the above background art.

[0005] A fitting casting mold for machining includes a protection box. The upper end of the protection box is fixedly connected with a feed inlet. One side of the feed inlet is provided with a release agent storage box, which is fixedly connected with the protection box. One side of the release agent storage box is fixedly connected with a connecting pipe, and the end of the connecting pipe far from the release agent storage box is fixedly connected with the protection box. The center of the lower end of the protection box is provided with an output port, and the outside of the output port is fixedly connected with a water tank. One side of the water tank is fixedly connected with a water inlet; The protection box includes a box body fixedly connected with the output port. Inside the box body, there is a fixed plate. On the side of the fixed plate close to the feed inlet, there is a fixed plate one. On the side of the fixed plate one far from the fixed plate, there is a fixed plate two. Both the fixed plate one and the fixed plate two are fixedly connected with the box body. There is a demolding area between the fixed plate and the fixed plate one, a casting area between the fixed plate one and the fixed plate two, a preparation area between the fixed plate two and the box body, and a power area between the fixed plate and the box body. The power area includes a hydraulic rod fixedly connected with the box body.

[0006] Preferably, several support columns are fixedly connected to the lower end of the protection box, several observation windows are fixedly connected to both sides of the protection box, a liquid meter is fixedly connected to the outer side of the water tank, an injection port is fixedly connected to the upper end of the release agent storage box, a purification box is arranged on one side of the release agent storage box away from the feed port, the purification box is fixedly connected to the protection box, and a discharge port is fixedly connected to the upper end of the purification box.

[0007] Preferably, the demolding area includes a moving plate slidably connected to the box body. An infusion pipe is connected between the lower end of the moving plate and the water tank. A connecting plate is fixedly connected to one side of the moving plate close to the first fixing plate. Several ejector pins are fixedly connected to the side of the connecting plate away from the moving plate. Springs are arranged on the outer sides of each ejector pin. One end of the spring close to the moving plate is fixedly connected to the connecting plate, and the end of the spring away from the connecting plate is fixedly connected to a moving mold. The moving mold is slidably connected to the spring. By arranging the spring, when the connecting plate is fixed, the spring can be driven by the hydraulic rod to eject the surface of the moving mold, thereby completing the ejection work of the plastic fittings. At the same time, when the movement of the connecting plate is not restricted, the spring can be flush with the surface of the moving mold, without affecting the normal casting work.

[0008] Preferably, several limiting rods are fixedly connected to one side of the first fixing plate close to the second fixing plate. The limiting rods penetrate through the moving plate, the connecting plate and the first fixing plate, and the end of the limiting rod away from the fixing plate is fixedly connected to the second fixing plate. A moving die is fixedly connected to the outer side of the moving mold. An infusion pipe is connected between the lower end of the moving die and the water tank. Connecting plates one are fixedly connected to both the upper and lower ends of the moving die. A connecting rod is fixedly connected to one side of the connecting plate one close to the connecting plate. The connecting rod penetrates through the moving plate, and a connecting plate two is fixedly connected to the side of the connecting rod away from the connecting plate one. The connecting plate two away from the connecting rod is fixedly connected to the hydraulic rod.

[0009] Preferably, several threaded parts are arranged inside the moving die, the threaded parts correspond to the positions of the limiting rods, and the threaded parts are all threadedly connected to the limiting rods. A gear is rotatably connected to the center of the moving die. A belt is connected between the gear and the threaded parts for transmission. A bevel gear is fixedly connected to the side of the gear close to the moving mold. Several bevel gears one are meshed with the outer side of the bevel gear. A rotating rod is fixedly connected to the center of each of the bevel gear one and the gear one.

[0010] Preferably, several cams are arranged on the rotating rod. The angles between the cams are different from each other, but the maximum angle difference does not exceed 180 degrees. A connecting block is movably connected to the side of the cam away from the threaded part. A first spring is fixedly connected to the side of the connecting block away from the cam. One end of the first spring away from the connecting block is fixedly connected to the movable mold. A sliding rod is arranged inside the first spring. One end of the sliding rod is fixedly connected to the first spring, and the end of the sliding rod away from the first spring is slidably connected to the movable mold. Since the angles between the cams are different from each other but the maximum angle difference does not exceed 180 degrees, there will be a time point when all the sliding rods are at the same height, and the time when each sliding rod separates from the surface of the movable mold is different, which can greatly reduce the impact on the plastic fitting when the movable mold separates from the plastic fitting, and prevent the plastic fitting from being damaged due to the excessive force of the sliding rod separating.

[0011] Preferably, the casting area includes a moving plate fixedly connected to the box body. A sliding groove is arranged inside the moving plate, and the sliding groove is slidably connected to the connecting pipe. One end of the connecting pipe away from the release agent storage tank is fixedly connected to a fixed mold. The fixed mold is slidably connected to the box body. A fixed die is fixedly connected to the center of the fixed mold. A casting pipe is fixedly connected to the side of the fixed die away from the hydraulic rod. A spiral pipe is arranged inside the casting pipe. The internal structure of the fixed die is the same as that of the movable die.

[0012] Preferably, the support frame includes a limiting block fixedly connected to the box body. A first moving plate is slidably connected to the upper end of the limiting block. A support frame is fixedly connected to the end of the first moving plate away from the limiting block. The end of the support frame away from the first moving plate is fixedly connected to the casting pipe. Several heating pipes are arranged on the casting pipe. A rotating part is fixedly connected to the end of the casting pipe away from the first fixed plate. An inlet is fixedly connected to the upper end of the rotating part. A telescopic part is fixedly connected to the end of the rotating part away from the first fixed plate. An induction block is arranged on the side of the telescopic part away from the rotating part. The induction block is fixedly connected to the box body.

[0013] Compared with the prior art, the advantages of the present invention are as follows: 1. In the present invention, by setting a demolding area, when the fixed mold moves to contact the first fixed plate in the demolding area, the fixed mold stops moving under the action of the first fixed plate. If the acting force between the plastic fitting and the fixed die is large, the plastic fitting will stay on the fixed mold. At this time, since the contact end between the plastic fitting and the fixed die is small, the plastic fitting will fall through the output port under the action of gravity. If the acting force between the plastic fitting and the movable mold is large, the plastic fitting will continue to move with the movable mold. When the moving plate moves to contact the fixed plate, the ejector pin will eject the plastic fitting from the movable mold to prevent the plastic fitting from staying on the movable mold.

[0014] 2. In the present invention, by providing a moving mold, when the moving mold slides on the limiting rod, the threaded part will start to rotate under the action of the thread, so that the sliding rod can continuously make reciprocating motions synchronously, reducing the adhesion between the plastic fitting and the mold, enabling the plastic fitting to easily disengage from the mold. At the same time, the angles between the cams are different but the maximum angle difference does not exceed 180 degrees, so there will be a time point when all the sliding rods are at the same height, which will not affect the normal casting of the mold. At the same time, when each sliding rod disengages from the plastic fitting, the other sliding rods will still provide a supporting force for the plastic fitting, greatly reducing the force required for the plastic fitting to disengage, and thus effectively reducing the phenomenon that the plastic fitting is damaged due to excessive force.

Detailed implementation manners Embodiment

[0029] Please refer to Figure 1 and Figure 2 As shown in and, a casting mold for mechanical processing accessories includes a protection box 2. A feed inlet 6 is fixedly connected to the upper end of the protection box 2. A demolding agent storage tank 10 is arranged on one side of the feed inlet 6. The demolding agent storage tank 10 is fixedly connected to the protection box 2. A connecting pipe 13 is fixedly connected to one side of the demolding agent storage tank 10. The end of the connecting pipe 13 away from the demolding agent storage tank 10 is fixedly connected to the protection box 2 shown. An output port 4 is arranged at the center of the lower end of the protection box 2. A water tank 3 is fixedly connected to the outside of the output port 4. A water inlet 5 is fixedly connected to one side of the water tank 3.

[0030] Please refer to Figure 3 and Figure 4, the protection box 2 includes a box body 201 fixedly connected to the output port 4. Inside the box body 201, there is a fixed plate 207 fixedly connected. On one side of the fixed plate 207 close to the feed port 6, there is a first fixed plate 208. On the side of the first fixed plate 208 away from the fixed plate 207, there is a second fixed plate 224. Both the first fixed plate 208 and the second fixed plate 224 are fixedly connected to the box body 201. Between the fixed plate 207 and the first fixed plate 208, there is a demolding area 203. Between the first fixed plate 208 and the second fixed plate 224, there is a casting area 204. Between the second fixed plate 224 and the box body 201, there is a preparation area 205. Between the fixed plate 207 and the box body 201, there is a power area 202. The power area 202 includes a hydraulic rod 206 fixedly connected to the box body 201.

[0031] Please refer to Figure 1 and Figure 2 , several support columns 1 are fixedly connected to the lower end of the protection box 2. Several observation windows 12 are fixedly connected to both sides of the protection box 2. A liquid level gauge 11 is fixedly connected to the outside of the water tank 3. An injection port 7 is fixedly connected to the upper end of the release agent storage box 10. A purification box 9 is arranged on the side of the release agent storage box 10 away from the feed port 6. The purification box 9 is fixedly connected to the protection box 2. An exhaust port 8 is fixedly connected to the upper end of the purification box 9.

[0032] Please refer to Figure 5 and Figure 6 , the demolding area 203 includes a moving plate 209 slidably connected to the box body 201. There is an infusion pipe connecting the lower end of the moving plate 209 to the water tank 3. On one side of the moving plate 209 close to the first fixed plate 208, there is a connecting plate 213 fixedly connected. On the side of the connecting plate 213 away from the moving plate 209, several ejector pins 215 are fixedly connected. A spring 214 is arranged outside each ejector pin 215. One end of the spring 214 close to the moving plate 209 is fixedly connected to the connecting plate 213. The other end of the spring 214 away from the connecting plate 213 is fixedly connected to a moving die 216. The moving die 216 is slidably connected to the spring 214. By arranging the spring 214, when the connecting plate 213 is fixed, the spring 214 can be driven by the hydraulic rod 206 to push out the surface of the moving die 216, thereby completing the ejection work of the plastic fittings. At the same time, when the movement of the connecting plate 213 is not restricted, the spring 214 can be flush with the surface of the moving die 216, without affecting the normal casting work.

[0033] Please refer to Figure 7 and Figure 8, on the side of the fixed plate 207 close to the first fixed plate 208, several limiting rods 210 are fixedly connected. The limiting rods 210 penetrate through the moving plate 209, the connecting plate 213 and the first fixed plate 208, and the end of the limiting rod 210 far from the fixed plate 207 is fixedly connected to the second fixed plate 224. On the outer side of the moving die 216, a moving mold 211 is fixedly connected. Between the lower end of the moving mold 211 and the water tank 3, there is an infusion pipe connected. At both the upper and lower ends of the moving mold 211, connecting plates one 217 are fixedly connected. On the side of the connecting plate one 217 close to the connecting plate 213, a connecting rod 212 is fixedly connected. The connecting rod 212 penetrates through the moving plate 209, and on the side of the connecting rod 212 far from the connecting plate one 217, a connecting plate two 219 is fixedly connected. On the side of the connecting plate two 219 far from the connecting rod 212, it is fixedly connected to the hydraulic rod 206.

[0034] Specifically, during the mold closing process, the hydraulic rod 206 will push the connecting plate two 219 to move. The movement of the connecting plate two 219 will synchronously push the moving plate 209 to move. The movement of the moving plate 209 will drive the connecting plate 213 to move. When the moving plate 209 moves to contact the first fixed plate 208, the first fixed plate 208 will limit the movement of the moving plate 209. At this time, the hydraulic rod 206 will still continue to push until the telescopic member 229 contacts the induction block 228. When the moving plate 209 moves, it will also drive the moving mold 211 to move synchronously through the connecting rod 212, so that the moving mold 211 can contact the fixed mold 220 to complete the mold closing. At the same time, during the mold opening process, the hydraulic rod 206 will pull the connecting plate two 219 to move. At this time, the plastic fitting cannot be completely pushed away from the mold, and there is adhesiveness between the two molds. Therefore, the movement of the moving plate 209 can drive the two molds to move synchronously, and the mold opening work can be completed during the movement. At the same time, when the moving plate 209 moves to contact the fixed plate 207, the hydraulic rod 206 will still continue to move, making the moving plate 209 stationary but the distance between the moving plate 209 and the moving mold 211 gradually decrease. As a result, the ejector pin 215 will eject the plastic fitting from the moving die 216 to prevent the plastic fitting from remaining on the moving die 216.

[0035] Please refer to Figure 9 and Figure 10 , inside the moving mold 211, several threaded members 233 are arranged. The threaded members 233 correspond to the positions of the limiting rods 210, and the threaded members 233 are all threadedly connected to the limiting rods 210. At the center of the moving mold 211, a gear 234 is rotatably connected. Between the gear 234 and the threaded members 233, a belt is connected for transmission. On the side of the gear 234 close to the moving die 216, a bevel gear 235 is fixedly connected. On the outer side of the bevel gear 235, several first bevel gears 236 are meshed. On the side of each first bevel gear 236 far from the bevel gear 235, a first gear 237 is meshed. At the centers of the first gear 237 and the first bevel gear 236, rotating rods 241 are fixedly connected.

[0036] Please refer to Figure 9 and Figure 10 On the rotating rod 241, several cams 238 are provided. The angles between the cams 238 are different from each other, but the maximum angle difference does not exceed 180 degrees. On the side of the cam 238 away from the threaded part 233, a connecting block 239 is movably connected. On the side of the connecting block 239 away from the cam 238, a first spring 218 is fixedly connected. One end of the first spring 218 away from the connecting block 239 is fixedly connected to the moving die 216. Inside the first spring 218, a sliding rod 240 is provided. One end of the sliding rod 240 is fixedly connected to the first spring 218, and the end of the sliding rod 240 away from the first spring 218 is slidably connected to the moving die 216. Since the angles between the cams 238 are different from each other but the maximum angle difference does not exceed 180 degrees, there will be a time point when all the sliding rods 240 are at the same height, and the time when each sliding rod 240 separates from the surface of the moving die 216 is different, which can greatly reduce the impact on the plastic fitting when the moving die 216 separates from the plastic fitting, and prevent the plastic fitting from being damaged due to the excessive force when the sliding rod 240 separates.

[0037] Specifically, when the moving die 211 slides on the limiting rod 210, the threaded part 233 will start to rotate under the action of the thread. The rotation of the threaded part 233 will drive the gear 234 to rotate through the belt. The rotation of the gear 234 will drive the bevel gear 235 to rotate synchronously. The rotation of the bevel gear 235 will cause the first bevel gear 236 to rotate, and then cause the first gear 237 to rotate synchronously. The rotation of the first bevel gear 236 and the first gear 237 will drive several cams 238 to rotate synchronously through the rotating rod 241, so that the connecting block 239 can continuously move up and down, so that the sliding rod 240 can continuously move back and forth synchronously, thereby reducing the adhesion between the plastic fitting and the mold, and enabling the plastic fitting to easily separate from the mold.

[0038] Please refer to Figure 11 and Figure 12 As shown in FIG. and FIG., the casting area 204 includes a moving plate 209 fixedly connected to the box body 201. Inside the moving plate 209, a sliding groove is provided. The sliding groove is slidably connected to the connecting pipe 13. One end of the connecting pipe 13 away from the release agent storage tank 10 is fixedly connected to a fixed die 220. The fixed die 220 is slidably connected to the box body 201. At the center of the fixed die 220, a fixed mold 221 is fixedly connected. On the side of the fixed mold 221 away from the hydraulic rod 206, a casting pipe 222 is fixedly connected. Inside the casting pipe 222, a spiral pipe is provided. The internal structure of the fixed mold 221 is the same as that of the moving die 211.

[0039] Specifically, during the mold closing process, when the moving mold 211 moves to contact the fixed mold 220 under the action of the hydraulic rod 206, the fixed mold 220 will move synchronously driven by the moving mold 211 until the fixed mold 220 contacts the second fixed plate 224, at which point the mold closing is completed. And when the fixed mold 220 leaves the first fixed plate 208, during the demolding process, due to the adhesion of the plastic fittings, the fixed mold 221 will move synchronously with the moving mold 211, and the demolding of the plastic fittings is completed during the movement. When the fixed mold 220 moves to contact the first fixed plate 208, the first fixed plate 208 will limit the movement of the fixed mold 220, enabling the plastic fittings to be removed through the output port 4. At the same time, when the fixed mold 220 contacts the first fixed plate 208, a certain amount of mold release agent in the mold release agent storage tank 10 will be poured into the fixed mold 221 through the connecting pipe 13.

[0040] Please refer to Figure 13 , the support frame 225 includes a limit block 231 fixedly connected to the box body 201. A first moving plate 226 is slidably connected to the upper end of the limit block 231. A support frame 225 is fixedly connected to one end of the first moving plate 226 away from the limit block 231. A casting pipe 222 is fixedly connected to one end of the support frame 225 away from the first moving plate 226. Several heating pipes 223 are arranged on the casting pipe 222. A rotating member 230 is fixedly connected to one end of the casting pipe 222 away from the first fixed plate 208. An inlet 227 is fixedly connected to the upper end of the rotating member 230. A telescopic member 229 is fixedly connected to one end of the rotating member 230 away from the first fixed plate 208. An induction block 228 is arranged on one side of the telescopic member 229 away from the rotating member 230, and the induction block 228 is fixedly connected to the box body 201.

[0041] Specifically, the plastic particles fall into the rotating member 230 from the feed port 6 through the inlet 227. Under the action of the spiral tube rotation in the casting pipe 222, the plastic particles will move towards the direction of the second fixed plate 224. At the same time, the plastic particles will be heated when passing through the heating pipes 223, enabling the plastic particles to reach the casting temperature. After a certain period of time, the telescopic member 229 controls the spiral tube in the casting pipe 222 to start moving, so that the output end of the spiral tube can contact the fixed mold 221 to complete the casting. When the casting is completed, the telescopic member 229 will control the spiral tube to reset. At the same time, the casting pipe 222 will move synchronously with the movement of the fixed mold 220, and the support frame 225 and the first moving plate 226 connected to the casting pipe 222 will move synchronously, making the state of the inlet 227 stable and not offset.

[0042] Working principle of the present invention: During the casting process, the hydraulic rod 206 pushes the second connecting plate 219 towards the first fixing plate 208. At the same time, after the second connecting plate 219 contacts the moving plate 209, it will drive the moving plate 209 to move synchronously. And the movement of the second connecting plate 219 will drive the moving die 211 to move synchronously through the connecting rod 212. When the moving plate 209 moves to contact the first fixing plate 208, at this time, the moving die 216 on the moving die 211 fits with the fixed die 221, and the telescopic member 229 also contacts the sensing block 228. At this time, the hydraulic rod 206 will stop moving. And the plastic particles fall from the feeding port 6 through the filling port 227 into the rotating member 230. Under the action of the rotation of the spiral tube in the casting tube 222, the plastic particles will move towards the second fixing plate 224. At the same time, the plastic particles will be heated when passing through the heating tube 223, so that the plastic particles can reach the casting temperature. After a certain time, the telescopic member 229 controls the spiral tube in the casting tube 222 to start moving, so that the output end of the spiral tube can contact the fixed die 221 to complete the casting; During the demoulding process, when the casting is completed, the telescopic member 229 will control the spiral tube to reset. At the same time, the hydraulic rod 206 drives the second connecting plate 219 to reset. During the movement of the second connecting plate 219, the moving die 211 will slide on the limiting rod 210. At this time, the threaded member 233 will start to rotate under the action of the thread. The rotation of the threaded member 233 will drive the gear 234 to rotate through the belt. The rotation of the gear 234 will drive the bevel gear 235 to rotate synchronously. The rotation of the bevel gear 235 will cause the first bevel gear 236 to rotate, and then the first gear 237 will rotate synchronously. The rotation of the first bevel gear 236 and the first gear 237 will drive several cams 238 to rotate synchronously through the rotating rod 241, so that the connecting block 239 can continuously move up and down reciprocally, so that the sliding rod 240 can continuously move reciprocally synchronously, thereby reducing the adhesion between the plastic fitting and the mold, making the plastic fitting and the mold loose. When the fixed die 220 moves to contact the first fixing plate 208, under the action of the first fixing plate 208, the fixed die 220 stops moving. If the acting force between the plastic fitting and the fixed die 221 is large, it will stay on the fixed die 220. At this time, because the contact end between the plastic fitting and the fixed die 221 is small, under the action of gravity, the plastic fitting will fall through the output port 4. If the acting force between the plastic fitting and the moving die 216 is large, the plastic fitting will continue to move with the moving die 216. When the moving plate 209 moves to contact the fixing plate 207, the hydraulic rod 206 will still continue to move. At this time, the moving plate 209 is fixed under the action of the fixing plate 207, but under the action of the hydraulic rod 206, the distance between the moving plate 209 and the moving die 211 gradually decreases, so that the ejector pin 215 will eject the plastic fitting from the moving die 216, preventing the plastic fitting from staying on the moving die 216. At this time, the demoulding work of the plastic fitting is completed.
