Description

Technical Field

[0001] The present invention relates to the technical field of casting molds, and particularly to a sizing mold with an arc-shaped slider structure. Background Art

[0002] A casting mold refers to a structure that is pre-made from other easily moldable materials to obtain the structural shape of a part. Then, the mold is placed in a sand mold, forming a cavity in the sand mold that is the same size and shape as the part. Next, a fluid with good fluidity is poured into the cavity. After the fluid cools and solidifies, a part with the same shape and structure as the mold is formed. After the part is formed, it needs to be removed from the casting mold.

[0003] The invention with the application number CN202311861823.9 discloses a hydrogen-eliminating casting mold, including a mold body, a rear template, and a front template. The rear template and the front template detachably fix the mold body between them. A mold core is arranged inside the mold body, and a feeding port is arranged at the bottom of the mold body. The feeding port penetrates to the outside of the front template. Exhaust holes are provided on all four sides of the mold body. A core-pulling oil cylinder is connected to each of the four sides of the mold body through an oil cylinder support frame. The core-pulling end of the core-pulling oil cylinder penetrates into the inside of the mold body. By setting the core-pulling oil cylinder, air and hydrogen can be effectively discharged, reducing the generation of bubbles and sand holes, improving the hardness and precision of the product, and thus reducing the risk of product deformation. Secondly, positioning holes and positioning screws are provided, making the fixation of the mold core and the mold body reliable and improving production stability. By precisely controlling the mold body, the shape and dimensional accuracy of the product are ensured.

[0004] When the existing casting mold is used to form a sleeve-like fitting with an arc-shaped structure, a moving structure with a linear movement is required to drive the arc-shaped rod to move closer to or away from the cavity to achieve mold closing and opening. Most of the moving structures with a linear movement are in a straight-line movement mode. Since the arc-shaped rod has a curvature and the forming groove of the cavity also has a curvature, when using a moving structure with a linear movement, moving structures with horizontal and vertical movements need to be set separately. This not only occupies a large amount of space but also has low precision after movement. For example, after being used multiple times, when the arc-shaped rod is located in the forming groove of the cavity, the distance between the arc-shaped rod and the groove wall of the forming groove is uneven, resulting in uneven thickness of the formed sleeve-like fitting. Summary of the Invention

[0005] The purpose of the present invention is to provide a sizing mold with an arc-shaped slider structure in view of the deficiencies of the prior art.

[0006] To achieve the above purpose, the technical solution of the present invention is as follows:

[0007] A sizing die with an arc-shaped slider structure, comprising an upper die module and a lower die module. A guiding structure is arranged between the upper die module and the lower die module. The guiding structure includes a guiding rod installed on the upper die module. The upper die module and the lower die module are respectively formed with die guiding holes that are slidably matched with the guiding rod;

[0008] The upper die module includes a moving module plate and a moving die core;

[0009] The lower die module includes a fixed module plate and a fixed die core;

[0010] The moving module plate is formed with a casting port for pouring molten metal, and the casting port is communicated with the moving die core; a sealing structure is arranged at the casting port. The sealing structure includes a sealing column installed at the casting port. The sealing column is formed with a hollow casting hole through which liquid can be poured. A plurality of arc-shaped side ring blocks are arranged at equal intervals in a ring shape on the outer ring part of the sealing column. An elastic structure for elastically ejecting the side ring blocks is arranged between the side ring blocks and the sealing column; a top block for blocking the casting hole is formed on the top of the side ring block;

[0011] The top surface of the moving die core is formed with an arc-shaped groove and a transverse groove for casting products. Demolding holes are formed at the bottoms of the arc-shaped groove and the transverse groove, and demolding rods that can slide axially are installed in the demolding holes;

[0012] The lower die module is provided with an arc-shaped moving structure, which includes an arc-shaped slider and moving guiding seats on both sides of the arc-shaped slider. The inner side walls of the moving guiding seats are longitudinally formed with protruding arc-shaped tracks, and the outer side walls of the arc-shaped slider are formed with arc-shaped chutes that are slidably matched with the arc-shaped tracks; an active support is arranged at the bottom of the arc-shaped slider. The active support includes a moving support seat. A moving swing block that can swing back and forth is installed on the top of the moving support seat. The top of the moving swing block is inclined and formed with an inclined track, and the bottom of the arc-shaped slider is inclined and formed with an inclined chute that is slidably matched with the inclined track;

[0013] An arc-shaped rod for forming sleeve-shaped products is installed on the front end surface of the arc-shaped slider, and the arc-shaped rod can extend into the arc-shaped groove. The bending diameters of the arc-shaped track, the arc-shaped chute, the arc-shaped rod, and the arc-shaped groove are the same.

[0014] Advantages of the present invention: When it is necessary to pour the casting liquid through the casting port, the sealing structure located at the casting port will work. The sealing column will pop out partially under the action of elasticity. At the same time, the side ring blocks on the outer ring part of the sealing column will radially spring open under the action of the elastic structure. The top stop block on the top of the side ring block cannot block the casting hole. At this time, the pouring head can be lowered and inserted into the casting hole to perform the operation of pouring the liquid. The liquid flows into the fixed mold core and the moving mold core through the sealing structure of the casting port. When it is necessary to let it stand and form the casting workpiece after the injection is completed, the pouring head is pulled out. The sealing structure will retract into the casting port under the action of elasticity. Its large elastic force can drive the side ring blocks to closely adhere to the sealing column. The top stop block located on the top of the side ring block exactly blocks the casting hole. At this time, the liquid cannot be poured, ensuring the sealing of the pouring port. Foreign objects from the outside cannot enter through the pouring port, thus ensuring the stability during the molding of the casting mold;

[0015] The arc-shaped slider is slidably matched with the arc-shaped track of the slide guide seat through the arc-shaped chute formed on the side. The arc-shaped slider realizes the movement of the arc-shaped trajectory; and the arc-shaped slider will not deviate, ensuring the stability of the movement. An arc-shaped rod for forming sleeve-like products is installed on the front end face of the arc-shaped slider. The curvature of the arc-shaped track is adapted to the curvature of the arc-shaped chute. The arc-shaped rod can extend into the arc-shaped chute. Since the bending diameters of the arc-shaped track, the arc-shaped chute, the arc-shaped rod, and the arc-shaped chute are the same and are all located on the same center of the circle, when the arc-shaped slider slides along the arc-shaped track through the arc-shaped chute, the arc-shaped rod installed on the arc-shaped slider moves in an arc-shaped trajectory, and during the movement, it is always coaxially aligned with the arc-shaped chute on the top surface of the moving mold core. After extending into the arc-shaped chute, the distance from the groove wall of the arc-shaped chute is appropriate, and the wall thickness of the formed sleeve-like product is relatively uniform, and the forming accuracy is relatively high; even if the arc-shaped rod is far from the arc-shaped chute, the arc-shaped rod and the arc-shaped chute can always maintain the trajectory on the same center of the circle.

[0061] The present invention will be described in detail below with reference to the accompanying drawings.

[0062] As Figures 1-11 shown, a sizing die with an arc-shaped slider structure includes an upper die module 1 and a lower die module 12. A guiding structure 112 is provided between the upper die module 1 and the lower die module 12. The guiding structure 112 includes a guiding rod 113 installed on the upper die module 1. The upper die module 1 and the lower die module 12 are respectively formed with die guiding holes 114 that are slidably matched with the guiding rod 113. The opening and closing of the die are realized through the sliding cooperation of the die guiding holes 114 and the guiding rod 113 between the upper die module 1 and the lower die module 12.

[0063] The upper die module 1 includes a movable module plate 11 and a movable die core 111; the lower die module 12 includes a fixed module plate 121 and a fixed die core 122.

[0064] The movable module plate 11 is formed with a casting port 2 for pouring molten metal. The casting port 2 is communicated with the movable die core 111. The casting port 2 is provided with a sealing structure 21. The sealing structure 21 includes a sealing column 213 installed on the casting port 2. The sealing column 213 is formed with a hollow casting hole 214 through which liquid can be poured. A plurality of side ring blocks 215 with arc-shaped structures are arranged at equal intervals in a ring shape on the outer ring part of the sealing column 213. An elastic structure for elastically ejecting the side ring blocks 215 is provided between the side ring blocks 215 and the sealing column 213. A top block 218 for blocking the casting hole 214 is formed at the top of the side ring block 215. When it is necessary to pour casting liquid through the casting port 2, the sealing structure 21 located at the casting port 2 will work. The sealing column 213 will pop out partially under the elastic action. At the same time, the side ring blocks 215 on the outer ring part of the sealing column 213 will radially expand under the action of the elastic structure. The top block 218 at the top of the side ring block 215 cannot block the casting hole 214. At this time, the pouring head can be lowered and inserted into the casting hole 214 to realize the operation of pouring liquid. The liquid flows into the fixed die core 122 and the movable die core 111 through the sealing structure 21 of the casting port 2. When it is necessary to let it stand and form a casting workpiece after the liquid injection is completed, the pouring head is pulled out. The sealing structure 21 will retract into the casting port 2 under the elastic action. Its relatively large elastic force can drive the side ring blocks 215 to closely adhere to the sealing column 213. The top block 218 located at the top of the side ring block 215 exactly blocks the casting hole 214. At this time, liquid cannot be poured, ensuring the sealing performance of the pouring port. Foreign matters from the outside cannot enter through the pouring port, thus ensuring the stability of the casting die during molding.

[0065] Specifically, a connecting ring 216 is sleeved and formed in the middle region of the sealing column 213. The bottom of the side ring block 215 is rotationally connected to the connecting ring 216 through a shaft hole structure. A limiting port 212 is formed at the top of the casting port 2, and the outer diameter of the limiting port 212 matches the outer diameter of the side ring block 215. When a part of the sealing structure 21 is elastically lifted, the side ring block 215 on the upper half of the sealing column 213 will swing radially outward around the connecting ring 216 under the elastic action. At this time, the top stop block 218 at the top of the side ring block 215 will move away from the casting hole 214, allowing the pouring head to be inserted for pouring operations. Conversely, the sealing column 213 of the sealing structure 21 will retract. At the same time, under the elastic action, the side ring blocks 215 are squeezed to approach each other, and the included angle with the sealing column 213 gradually becomes smaller. After the sealing column 213 retracts in place, the side ring blocks 215 are located in the limiting port 212. At this time, the top stop blocks 218 at the tops of the multiple side ring blocks 215 just block the casting hole 214 to prevent other sundries from entering the casting port 2.

[0066] Furthermore, a flow groove 211 for the pouring liquid to flow is formed at the bottom of the casting port 2. The bottom of the sealing column 213 extends towards the flow groove 211, and a stop ring 219 is formed at the bottom of the sealing column 213. The stop ring 219 is in stop cooperation with the bottom of the casting port 2. When the sealing column 213 pops out under the elastic action, under the action of the stop ring 219, only a part will pop out, and the popped part is just enough for the side ring block 215 to pop out radially, and the top stop block 218 moves radially away from the pouring hole.

[0067] Furthermore, a hole structure 22 is formed on the periphery of the casting mouth 2 of the movable mold plate 11, and the hole structure 22 includes a first downward pressure hole 221 and a second downward pressure hole 222, and a U-shaped hole 223 is connected between the first downward pressure hole 221 and the second downward pressure hole 222, and a U-shaped connecting strip 226 is installed in the U-shaped hole 223, and a first movable rod 224 connected to the U-shaped connecting strip 226 is movably installed in the first downward pressure hole 221, and the top of the first movable rod 224 protrudes out of the hole, and a second movable block 225 connected to the U-shaped connecting strip 226 is movably installed in the second downward pressure hole 222, wherein the second downward pressure hole 222 is connected to the casting mouth 2, and the second movable block 225 is connected to the sealing column 213. Initially, the first movable rod 224 is raised under the action of elasticity, and the second movable block 225 located at the second downward pressure hole 222 is located near the bottom area of ​​the second downward pressure hole 222. At the same time, the sealing column 213 of the sealing structure 21 is tightly installed in the casting port 2, and the side ring block 215 is in contact with the sealing column 213, and the top ring block on the top of the side ring block 215 seals and blocks the casting port 2. On the contrary, when the first movable rod 224 is pressed down, the second movable block 225 located at the second downward pressure hole 222 will be axially raised under the action of the U-shaped connecting strip 226, thereby driving the sealing column 213 of the sealing structure 21 to rise, and the side ring block 215 located at the periphery of the sealing column 213 will be radially opened under the action of the elastic structure, and the top stopper 218 on the top of the side ring block 215 will not block the liquid extraction hole. At this time, the pouring head can be lowered and inserted into the pouring hole to realize the pouring operation.

[0068] Specifically, a first compression spring 227 sleeved on the first movable rod 224 is provided in the first pressing hole 221, and the first compression spring 227 can elastically drive the first movable rod 224 to rise, and the elastic structure is a second compression spring 217 connected between the side ring block 215 and the sealing column 213, wherein the elastic force of the first compression spring 227 is greater than the elastic force of the second compression spring 217, the side ring block 215 is arranged longitudinally, the bottom of the side ring block 215 is rotatably connected with the sealing column 213, and the second compression spring 217 can elastically drive the side ring block 215 to elastically pop outward around the bottom end of the sealing column 213. Initially, under the action of the first compression spring 227, the first movable rod 224 located in the first pressing hole 221 will rise a part, thereby driving the U-shaped connecting strip 226 to move along the U-shaped hole 223 close to the first pressing hole 221, and at the same time, the second movable block 225 located in the second pressing hole 222 can move downward to drive the sealing column 213 of the sealing structure 21 to retreat along the casting port 2. Since the elastic force of the first compression spring 227 is greater than the elastic force of the second compression spring 217, the side ring block 215 located outside the sealing column 213 will be squeezed into the limiting opening 212 and be in a contracted and closed state. The top stopper 218 blocks the casting hole 214 to prevent other debris from entering the casting opening 2.

[0069] In addition, the lower die module 12 is provided with an opening component 23 that drives the first movable rod 224 to move longitudinally. The opening component 23 includes a longitudinal opening column 231. Along the length direction of the opening column 231, a longitudinally arranged hydraulic cylinder 232 is installed. The driving end of the hydraulic cylinder 232 is installed with a lifting pressure seat 233. The opening column 231 is longitudinally provided with a guiding track 234 for the guiding movement of the lifting pressure seat 233. The lifting pressure seat 233 is longitudinally coaxially aligned with the first movable rod 224. When liquid needs to be poured, the opening component 23 works. The hydraulic cylinder 232 located on the opening column 231 works. The lifting pressure seat 233 at its driving end descends along the guiding track 234 and contacts the top of the first movable rod 224, continuously pressing down, so that the whole first movable rod 224 is axially pressed down along the first pressing hole 221. According to the above principle, the sealing structure 21 of the casting port 2 works, and the whole will rise up a part, and the casting hole 214 of the sealing column 213 will be opened. The pouring head can be inserted into the casting hole 214 to perform the operation of pouring liquid. When the pouring is completed and the casting mold needs to be static for the product to form, the hydraulic cylinder 232 of the opening component 23 works, and the lifting pressure seat 233 retracts. At this time, the first movable rod 224 rises under the action of the first compression spring 227; at the same time, it drives the whole sealing column 213 of the sealing module to retract. The side ring block 215 outside the sealing column 213 will be squeezed into the limiting port 212 and be in a state of shrinking and approaching, and the top stop block 218 blocks the casting hole 214.

[0070] It should be noted that the first movable rod 224 is formed with radially arranged stop pieces along the way. The first pressing hole 221 is formed with an inner movable hole 228 along the way. The inner movable hole 228 allows the stop block 229 to move axially. The first compression spring 227 is located in the inner movable hole 228. The top of the first compression spring 227 is installed at the bottom of the stop block 229. Under the elastic drive of the first compression spring 227, the first movable rod 224 will bounce up until the top of the stop block 229 is in stop cooperation with the first pressing hole 221, which can prevent the whole first movable rod 224 from falling off the first pressing hole 221.

[0071] The top surface of the moving mold core 111 is formed with an arc-shaped groove 115 for casting products. Demolding holes 117 are formed at the bottom of the arc-shaped groove 115, and demolding rods 126 capable of axial sliding are installed in the demolding holes 117. The lower mold module 12 is provided with an arc-shaped slider structure 3, which includes an arc-shaped slider 31 and slider guides 311 located on both sides of the arc-shaped slider 31. A convex arc-shaped track 312 is longitudinally formed on the inner side wall of the slider guide 311, and an arc-shaped chute 313 that slidably cooperates with the arc-shaped track 312 is formed on the outer side wall of the arc-shaped slider 31. The arc-shaped slider 31 slidably cooperates with the arc-shaped track 312 of the slider guide 311 through the arc-shaped chute 313 formed on the side, and the arc-shaped slider 31 realizes the movement of an arc-shaped trajectory; moreover, the arc-shaped slider 31 will not deviate, ensuring the stability of the movement. An arc-shaped rod 310 for forming sleeve-shaped products is installed on the front end face of the arc-shaped slider 31. The curvature of the arc-shaped track 312 is adapted to the curvature of the arc-shaped groove 115. The arc-shaped rod 310 can extend into the arc-shaped groove 115. Due to the arc-shaped groove 115 on the top surface of the moving mold core 111, the movement of the arc-shaped trajectory is realized through the arc-shaped slider 31, so that the arc-shaped rod 310 can match the arc-shaped groove 115. When the mold is closed, the arc-shaped rod 310 can approach along the trajectory direction of the arc-shaped groove 115 and always maintain a coaxially aligned state with the arc-shaped groove 115, ensuring that the wall thickness of the formed sleeve-shaped products is uniform and the accuracy is higher.

[0072] Furthermore, the bending diameters of the arc-shaped track 312, the arc-shaped chute 313, the arc-shaped rod 310, and the arc-shaped groove 115 are the same and are all located at the same center of the circle. Therefore, when the arc-shaped slider 31 slides along the arc-shaped track 312 through the arc-shaped chute 313, the arc-shaped rod 310 installed on the arc-shaped slider 31 moves along an arc-shaped trajectory, and during the movement, it is always coaxially aligned with the arc-shaped groove 115 on the top surface of the moving mold core 111. After extending into the arc-shaped groove 115, it is adapted to the distance from the groove wall of the arc-shaped groove 115, and the wall thickness of the formed sleeve-shaped products is relatively uniform, and the forming accuracy is higher; even when the arc-shaped rod 310 is far away from the arc-shaped groove 115, the arc-shaped rod 310 and the arc-shaped groove 115 can still maintain a trajectory at the same center of the circle.

[0073] Further, an active support member 314 is provided at the bottom of the arc-shaped slider 31. The active support member 314 includes a slider support base 328. A slider swing block 315 capable of swinging back and forth is installed on the top of the slider support base 328. The top of the slider swing block 315 is arranged obliquely and formed with an inclined track 316. The bottom of the arc-shaped slider 31 is arranged obliquely and formed with an inclined chute 317 that is slidably engaged with the inclined track 316. The slider swing block 315 swings around the top of the slider support base 328 through a shaft-hole structure. When the slider swing block 315 swings up and down, its height will change accordingly. Therefore, the slider swing block 315 and the arc-shaped slider 31 will be slidably engaged through the inclined track 316 and the inclined chute 317, thereby driving the arc-shaped slider 31 to slide along the arc track 312 of the slider guide base 311. The arc-shaped rod 310 installed at the inner end of the arc-shaped slider 31 coaxially approaches or moves away from the arc groove 115 on the top surface of the moving mold core 111, realizing mold clamping and demolding.

[0074] Further, a fixed mold fixing plate 123 is provided below the fixed mold template 121. Support vertical plates 129 are installed at the tops of both sides of the fixed mold fixing plate 123. The fixed mold fixing plate 123 is provided with a bottom installation groove 128 for installing the slider support base 328. A guiding lifting cylinder 318 is arranged inside the slider support base 328. A longitudinal moving block 319 is installed at the driving end of the guiding lifting cylinder 318. The top of the longitudinal moving block 319 is rotatably connected to the slider swing block 315 through a shaft-hole structure. The guiding lifting cylinder 318 can drive the longitudinal moving block 319 to move up and down. When the longitudinal moving block 319 rises, the slider swing block 315 and the arc-shaped slider 31 will be slidably engaged through the inclined track 316 and the inclined chute 317, and the top of the slider swing block 315 will slide to a position near the bottom of the inclined chute 317. The arc-shaped slider 31 approaches the moving mold core 111, and the included angle between the slider swing block 315 and the longitudinal moving block 319 increases, realizing the adaptive change of the position of the arc-shaped rod 310 and realizing the mold clamping operation. On the contrary, when the longitudinal moving block 319 descends, the slider swing block 315 and the arc-shaped slider 31 will be slidably engaged through the inclined track 316 and the inclined chute 317, and the top of the slider swing block 315 will slide to a position near the top of the inclined chute 317. The arc-shaped slider 31 moves away from the moving mold core 111, and the included angle between the slider swing block 315 and the longitudinal moving block 319 becomes smaller, realizing the adaptive change of the position of the arc-shaped rod 310 and realizing the demolding.

[0075] Preferably, the lower die module 12 is provided with a guiding lateral sliding structure 32. The guiding lateral sliding structure 32 includes a guiding lateral sliding block 321. A guiding mounting seat 322 is installed on the guiding lateral sliding block 321. A positioning linear guiding groove 323 for the guiding lateral sliding block 321 to linearly approach or move away from the fixed die core 122 is formed at the top of the fixed die module plate 121. A positioning seat 324 capable of abutting against the arc-shaped sliding block 31 is installed at the inner end of the guiding mounting seat 322. The positioning seat 324 is arranged horizontally. An inclined guiding inclined hole 325 is formed on the guiding lateral sliding block 321. A guiding sliding rod 326 slidably engaged with the guiding inclined hole 325 is installed at the bottom of the moving die core 111. A right-angle groove 327 for a part of the positioning seat 324 to be embedded is formed on the back of the arc-shaped sliding block 31. In this embodiment, during mold closing, driven by the guiding lifting air cylinder 318, the arc-shaped sliding block 31 approaches the moving die core 111, and the included angle between the sliding block swing block 315 and the longitudinal moving block 319 increases. The arc-shaped rod 310 coaxially approaches or moves away from the arc-shaped groove 115 on the top surface of the moving die core 111 to realize the mold closing operation. At the same time, the upper die module 1 descends and approaches the fixed die module. The guiding sliding rod 326 installed on the moving die core 111 is slidably engaged with the guiding inclined hole 325 of the guiding lateral sliding block 321 to drive the guiding lateral sliding block 321 to approach the moving die core 111 along the positioning linear guiding groove 323. When the upper die module 1 is in contact with the fixed die module, the mold closing is completed. After mold closing, the positioning seat 324 at the inner end of the guiding mounting seat 322 just abuts against the right-angle groove 327 on the back of the arc-shaped sliding block 31 to clamp the arc-shaped sliding block 31 and prevent the arc-shaped sliding block 31 from shifting. The arc-shaped rod 310 installed on the arc-shaped sliding block 31 remains coaxially located in the arc-shaped groove 115, which helps to improve the forming accuracy of sleeve-like products.

[0076] The top surface of the moving mold core 111 is formed with transverse slots 116 for casting products. Demolding holes 117 are formed at the bottoms of the transverse slots 116, and demolding rods 126 capable of axial sliding are installed in the demolding holes 117. The lower mold module 12 is provided with a first transverse moving structure 4. The first transverse moving structure 4 includes a first transverse moving slider 41. A first mounting seat 42 is installed on the first transverse moving slider 41. A transverse moving rod 5 for forming hole positions is installed at the inner end of the first mounting seat 42. A first linear guiding slot 43 for the first transverse moving slider 41 to linearly approach or move away from the fixed mold core 122 is formed at the top of the fixed mold plate 121. An inclined first inclined guiding hole 44 is formed through the first transverse moving slider 41. A first moving guiding rod 45 slidably engaged with the first inclined guiding hole 44 is installed at the bottom of the moving mold core 111. When the mold is closed, the upper mold module 1 descends and approaches the fixed mold module. The first moving guiding rod 45 installed on the moving mold core 111 is slidably engaged with the first inclined guiding hole 44 of the transverse moving slider to drive the first transverse moving slider 41 to approach the moving mold core 111 along the first linear guiding slot 43. The transverse moving rod 5 installed on the first mounting seat 42 can continuously approach the transverse slot 116. When the upper mold module 1 is in contact with the fixed mold module, the mold closing is completed. On the contrary, when demolding, the upper mold module 1 ascends and moves away from the fixed mold module. The first moving guiding rod 45 is slidably engaged with the first inclined guiding hole 44, and the first transverse moving slider 41 moves away from the moving mold core 111 along the first linear guiding slot 43 to realize the demolding of the transverse slot 116.

[0077] In addition, when processing hole positions with different outer diameters for the same product, it is usually necessary to re - design and mold the moving rod. In this regard, the present invention has a different idea. The transverse moving rod 5 includes a first forming rod 51 formed on the first mounting seat 42 and a second forming rod 52 inserted into the transverse slot 116. A third forming rod 53 is detachably sleeved on the second forming rod 52. A connecting structure 6 is provided between the third forming rod 53 and the second forming rod 52. Through the connecting structure 6, the third forming rod 53 and the second forming rod 52 are detachably connected. According to the requirements of the product, the third forming rod 53 can be sleeved or not sleeved on the second forming rod 52 to be used for forming different hole diameters.

[0078] Specifically, the connecting structure 6 includes a first locking groove 61 and a second locking groove 62 provided at the outer end of the second forming rod 52. Both the first locking groove 61 and the second locking groove 62 are formed with an arc-shaped periphery on the outer wall of the second forming rod 52. The first locking groove 61 and the second locking groove 62 are arranged at intervals, and are axially staggered on the second forming rod 52 between the first locking groove 61 and the second locking groove 62. The end of the first locking groove 61 is axially aligned with the front end of the second locking groove 62. A third locking groove 63 is communicated between the first locking groove 61 and the second locking groove 62, and the third locking groove 63 is arranged along the length direction of the second forming rod 52. The first locking groove 61, the second locking groove 62 and the third locking groove 63 communicate with each other to form a structure similar to a "zigzag" shape. The third forming rod 53 is formed with a plugging hole 65 having a through-hole structure. The inner diameter of the plugging hole 65 is adapted to the outer diameter of the second forming rod 52 and can be inserted by the second forming rod 52. A radially arranged elastic groove 67 is formed in the plugging hole 65, and a locking block 66 that pops radially into the plugging hole 65 is installed in the elastic groove 67. The locking block 66 can slide along the first locking groove 61, the second locking groove 62 and the third locking groove 63. An upward or downward locking groove 64 is formed at the end of the third locking groove 63. When the locking block 66 slides to the locking groove 64, the locking block 66 cannot continue to move laterally. At this time, the third forming rod 53 cannot be rotated, thus ensuring the connection between the first forming rod 51 and the second forming rod 52, preventing loosening, and ensuring the accuracy of the parts after casting.

[0079] When installing the third forming rod 53, it is inserted into the second forming rod 52. The locking block 66 can retract under the elastic action of the elastic groove 67 until the locking block 66 is aligned with the first locking groove 61. At this time, the locking block 66 can pop out under the elastic action to cooperate with the first locking groove 61. By continuously pushing and rotating, the locking block 66 slides along the paths of the first locking groove 61, the second locking groove 62 and the third locking groove 63 in sequence, achieving the installation in place. At this time, the third forming rod 53 will not fall off from the second forming rod 52, realizing the locking connection.

[0080] It should be noted that the first locking groove 61, the second locking groove 62 and the third locking groove 63 are all formed at the outer end portion of the second forming rod 52. The outer end portion of the second forming rod 52 is located outside the lower die insert. When the third forming rod 53 is not used, the connecting structure 6 of the second forming rod 52 will not affect the hole position forming of the casting. The size of the third forming rod 53 can be various. The size of its inner hole is a fixed value, and the outer diameter can be processed into multiple sets of different third forming rods 53 according to the hole diameter requirements of the product for cooperation with the second forming rod 52. Without disassembling the fixed mold core 122 and the slider assembly, the processing of different inclined hole sizes can be completed, which not only saves time but also greatly reduces the cost.

[0081] A fixed mold template 121 is provided with a fixed mold fixing plate 123 below. A thimble plate 124 is installed at the bottom of the fixed mold fixing plate 123. And the fixed mold fixing plate 123 is provided with a bottom guiding hole 125 for a demolding rod 126 to pass through. The bottom of the demolding rod 126 is installed on the thimble plate 124. A bottom support seat 118 is installed at the bottom of the fixed mold fixing plate 123, so that there is a gap between the fixed mold fixing plate 123 and the ground. A demolding lifting cylinder 127 is installed at the bottom of the fixed mold fixing plate 123. The demolding lifting cylinder 127 is connected to the thimble plate 124. During demolding, the thimble plate 124 is driven to rise by the demolding lifting cylinder 127. After the demolding rod 126 of the thimble plate 124 passes through the bottom guiding hole 125 of the fixed mold fixing plate 123 and the demolding hole 117 of the fixed mold core 122, the product located in the arc groove 115 and the transverse groove 116 of the fixed mold core 122 is ejected to achieve demolding.

[0082] In summary, it can be seen that the present invention has the excellent characteristics described above, so that it can enhance the effectiveness never before achieved in the prior art during use and has practicality, becoming a product with extremely high practical value.

[0083] The above content is only a preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
