Description

Technical Field

[0001] The invention relates to the technical field of casting mold design, and in particular to a shaping mold with an arc-shaped sliding block structure. Background Art

[0002] A casting mold is a material that is made of other easily moldable materials in advance in order to obtain the structural shape of a part. The mold is then placed in a sand mold, forming a cavity with the same size as the part structure. A flowing liquid is then poured into the cavity. After the liquid cools and solidifies, a part with the same shape and structure as the mold can be formed. After the part is formed, it needs to be taken out of the casting mold.

[0003] The invention with application number CN202311861823.9 discloses a hydrogen-free casting mold, including a mold body, a rear template and a front template, wherein the rear template and the front template are detachably fixed to fix the mold body between the two, a mold core is arranged inside the mold body, a feed port is arranged at the bottom of the mold body, and the feed port penetrates to the outside of the front template, exhaust holes are arranged around the mold body, and a core-pulling cylinder is arranged on all four sides of the mold body through a cylinder support frame, and the core-pulling end of the core-pulling cylinder penetrates to the inside of the mold body. The present invention effectively discharges air and hydrogen by arranging a core-pulling cylinder, reduces the generation of bubbles and sand holes, improves the hardness and precision of the product, and thus reduces the risk of product deformation. Secondly, positioning holes and positioning screws are arranged to make the mold core and the mold body reliably fixed, improve production stability, and ensure the shape and dimensional accuracy of the product by precisely controlling the mold body.

[0004] When casting sleeve-type accessories with arc-shaped structures, the existing casting mold needs to use the movement of the sliding structure to drive the arc rod to move closer to or away from the cavity to achieve mold closing and opening. Most of the sliding structures are in a linear movement mode. Since the arc rod has an arc and the molding groove of the cavity also has an arc, the use of a linear movement sliding structure requires the provision of horizontal and vertical movement sliding structures respectively. Not only does it take up a large space, but the accuracy after movement is also low. For example, after being used many times, when the arc rod is located in the molding groove of the cavity, the distance between the arc rod and the groove wall of the molding groove is uneven, resulting in uneven thickness of the molded sleeve-type accessories. Summary of the invention

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

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

[0007] A shaping die with an arc-shaped slider structure comprises an upper die set and a lower die set, a guide structure is arranged between the upper die set and the lower die set, the guide structure comprises a guide rod installed on the upper die set, and the upper die set and the lower die set are respectively formed with a die guide hole that slides with the guide rod;

[0008] The upper mold assembly includes a movable mold assembly plate and a movable mold core;

[0009] The lower mold assembly includes a fixed mold assembly plate and a fixed mold core;

[0010] The movable mold plate is formed with a casting port for pouring molten metal, and the casting port is connected with the movable mold core; the casting port is provided with a sealing structure, and the sealing structure includes a sealing column installed at the casting port, and the sealing column penetrates a casting hole formed with a hollow structure, and the casting hole can be poured with liquid, and the outer ring part of the sealing column is annularly arranged with a plurality of side ring blocks of arc structure at equal intervals, and an elastic structure for elastically ejecting the side ring block is provided between the side ring block and the sealing column; a top stopper for shielding the casting hole is formed on the top of the side ring block;

[0011] The top surface of the dynamic mold core is formed with an arc groove and a transverse groove for casting products, and the bottom of the arc groove and the transverse groove are both formed with demoulding holes, and the demoulding holes are equipped with demoulding rods that can slide axially;

[0012] The lower mold module is provided with an arc-shaped slide structure, which includes an arc-shaped slider and a slide guide seat located on both sides of the arc-shaped slider, the inner side wall of the slide guide seat is longitudinally formed with a raised arc track, and the outer side wall of the arc-shaped slider is formed with an arc-shaped slide groove that slidably cooperates with the arc track; a movable support member is provided at the bottom of the arc-shaped slider, and the movable support member includes a slide support seat, and a slide swing block that can swing back and forth is installed on the top of the slide support seat, the top of the slide swing block is tilted and formed with an inclined track, and the bottom of the arc-shaped slider is tilted and formed with an inclined slide groove that slidably cooperates with the inclined track;

[0013] The front end surface of the arc-shaped slider is equipped with an arc-shaped rod for forming sleeve-type products, and the arc-shaped rod can extend into the arc-shaped groove. The bending diameters of the arc-shaped track, the arc-shaped slide groove, the arc-shaped rod and the arc-shaped groove are the same.

[0014] The beneficial effects of the present invention are as follows: when it is necessary to pour casting liquid through the casting port, the sealing structure located at the casting port will work, and a portion of the sealing column will pop outward under the action of elasticity. At the same time, the side ring block on the outer ring of the sealing column will radially spring open under the action of the elastic structure, and the top 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 realize the operation of pouring liquid, and the liquid flows into the fixed model core and the movable model core through the sealing structure of the casting port. When the casting workpiece needs to be left to stand for molding after the liquid injection is completed, the pouring head is pulled out, and the sealing structure will retreat into the casting port under the action of elasticity. Its larger elastic force can drive the side ring block to be close to the sealing column, and the top block on the top of the side ring block just blocks the casting hole. At this time, liquid cannot be poured, ensuring the sealing of the pouring port, and external debris cannot enter through the pouring port, thereby ensuring the stability of the casting mold during molding;

[0015] The arc slider slides with the arc track of the guide seat through the arc slide groove formed on the side, and the arc slider realizes the movement of the arc track; and the arc slider will not be offset, ensuring the stability of movement. The front end of the arc slider is installed with an arc rod for forming sleeve products. The curvature of the arc track is adapted to the curvature of the arc slot, and the arc rod can be extended into the arc slot. Since the curvature diameters of the arc track, the arc slide groove, the arc rod and the arc slot are the same and are all located at the same center of the circle, when the arc slider slides along the arc track guide through the arc slide groove, the arc rod installed on the arc slider moves in an arc track, and when moving, it is always coaxially aligned with the arc slot on the top surface of the dynamic model core. After extending into the arc slot, it is adapted to the slot wall spacing of the arc slot, so that the wall thickness of the sleeve product formed is relatively uniform and the forming accuracy is high; even if the arc rod is far away from the arc slot, the arc rod and the arc slot can always remain on the same track of the center of the circle.

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

[0062] like Figure 1-11 As shown, a shaping mold with an arc-shaped slider structure includes an upper mold module 1 and a lower mold module 12, a guide structure 112 is arranged between the upper mold module 1 and the lower mold module 12, the guide structure 112 includes a guide rod 113 installed on the upper mold module 1, the upper mold module 1 and the lower mold module 12 are respectively formed with mold guide holes 114 that slide with the guide rod 113, and the upper mold module 1 and the lower mold module 12 are opened and closed by slidingly matching the mold guide holes 114 and the guide rod 113.

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

[0064] The movable mold assembly plate 11 is formed with a casting port 2 for pouring molten metal, and the casting port 2 is connected to the movable mold core 111; the casting port 2 is provided with a sealing structure 21, and the sealing structure 21 includes a sealing column 213 installed on the casting port 2, and the sealing column 213 penetrates a casting hole 214 formed with a hollow structure, and the casting hole 214 can be poured with liquid. The outer ring part of the sealing column 213 is annularly arranged with a plurality of side ring blocks 215 of arc structure at equal intervals, and an elastic structure for elastically popping out the side ring block 215 is provided between the side ring block 215 and the sealing column 213; the top of the side ring block 215 is formed with a casting hole 214 is blocked by the top stopper 218; when it is necessary to pour the casting liquid through the casting port 2, the sealing structure 21 located at the casting port 2 will work, and the sealing column 213 will pop out partially under the elastic action, and at the same time, the side ring block 215 on the outer ring part of the sealing column 213 will radially bounce open under the action of the elastic structure, and the top stopper 218 on 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, and the liquid flows into the fixed model core 122 and the movable model core 111 through the sealing structure 21 of the casting port 2. When the casting workpiece needs to be left to stand for forming after the injection is completed, the pouring head is pulled out, and the sealing structure 21 will retreat into the casting port 2 under the action of elasticity. Its larger elastic force can drive the side ring block 215 to fit tightly against the sealing column 213. The top stopper 218 located on the top of the side ring block 215 just blocks the casting hole 214. At this time, liquid cannot be poured, ensuring the sealing of the pouring port, and external debris cannot enter through the pouring port, thereby ensuring the stability of the casting mold during molding.

[0065] Specifically, a connecting ring 216 is sleeved and formed in the middle area of ​​the sealing column 213, and the bottom of the side ring block 215 is rotatably connected to the connecting ring 216 through an axial hole structure. A limiting opening 212 is formed at the top of the casting port 2, and the outer diameter of the limiting opening 212 matches the outer diameter of the side ring block 215. When a part of the sealing structure 21 is elastically lifted up, the side ring block 215 located at the upper half of the sealing column 213 will swing radially outward around the connecting ring 216 under the action of elasticity. At this time, the top stopper 218 located at the top of the side ring block 215 is away from the casting hole 214, allowing the pouring head to be inserted to realize the pouring operation; on the contrary, the sealing column 213 of the sealing structure 21 will retreat, and at the same time, under the action of elasticity, the side ring blocks 215 are squeezed close to each other, and the angle with the sealing column 213 gradually becomes smaller. After the sealing column 213 retracts into place, the side ring block 215 is located in the limit opening 212. At this time, the top stoppers 218 on the tops of multiple side ring blocks 215 just block the casting hole 214 to prevent other debris 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, and the bottom of the sealing column 213 extends toward the flow groove 211. A stop ring 219 is formed at the bottom of the sealing column 213, and the stop ring 219 cooperates with the stopper at the bottom of the casting port 2; when the sealing column 213 pops out under the action of elasticity, only a part of it will pop out under the action of the stop ring 219, and the popped-out part is just enough for the side ring block 215 to pop out radially, and the top stop block 218 is radially away from the casting 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 mold module 12 is provided with a hole-opening component 23 for driving the first movable rod 224 to move longitudinally. The hole-opening component 23 includes a longitudinal hole-opening column 231. The hole-opening column 231 is provided with a longitudinally arranged hydraulic cylinder 232 along the length direction. The driving end of the hydraulic cylinder 232 is provided with a lifting and lowering seat 233. The hole-opening column 231 is longitudinally provided with a guide track 234 for guiding the lifting and lowering seat 233 to move. The lifting and lowering seat 233 is longitudinally coaxially aligned with the first movable rod 224. When it is necessary to pour liquid, the hole-opening component 231 is provided with a longitudinal hole-opening column 231. The hole-opening column 231 is provided with a longitudinally arranged hydraulic cylinder 232 along the length direction. The driving end of the hydraulic cylinder 232 is provided with a lifting and lowering seat 233. The lifting and lowering seat 233 is longitudinally coaxially aligned with the first movable rod 224. When the component 23 works, the hydraulic cylinder 232 located at the opening column 231 works, and the lifting and pressing seat 233 at its driving end descends along the guide rail 234, contacts the top of the first movable rod 224, and continuously presses down, so that the first movable rod 224 is pressed down along the first downward pressure hole 221 as a whole. According to the above principle, the sealing structure 21 of the casting port 2 works, and a part of the whole will rise, and the casting hole 214 of the sealing column 213 will be opened, and the pouring head can be inserted into the casting hole 214 to perform the operation of pouring liquid. When the pouring is completed, the casting mold needs to be left still for the product to be formed, and the hydraulic cylinder 232 of the opening component 23 works, and the lifting and pressing seat 233 retreats. At this time, the first movable rod 224 rises under the action of the first compression spring 227; at the same time, the sealing column 213 of the sealing module is driven to retreat as a whole, and the side ring block 215 outside the sealing column 213 will be squeezed into the limit port 212, in a contracted and close state, and the top stopper 218 blocks the casting hole 214.

[0070] It should be noted that the first movable rod 224 is formed with radially arranged stop plates along the way, and the first downward pressure 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, and the top of the first compression spring 227 is installed on the bottom of the stop block 229. Under the elastic drive of the first compression spring 227, the first movable rod 224 will bounce upward until the top of the stop block 229 cooperates with the stop of the first downward pressure hole 221, which can prevent the first movable rod 224 from falling off from the first downward pressure hole 221 as a whole.

[0071] The top surface of the dynamic model core 111 is formed with an arc groove 115 for casting products, and the bottom of the arc groove 115 is formed with a demoulding hole 117, and the demoulding hole 117 is installed with a demoulding rod 126 that can slide axially. The lower mold module 12 is provided with an arc-shaped slide structure 3, which includes an arc-shaped slider 31 and a slider guide seat 311 located on both sides of the arc-shaped slider 31. The inner side wall of the slider guide seat 311 is longitudinally formed with a raised arc track 312, and the outer side wall of the arc-shaped slider 31 is formed with an arc-shaped slide groove 313 that slides with the arc track 312; the arc-shaped slider 31 slides with the arc track 312 of the slider guide seat 311 through the arc-shaped slide groove 313 formed on the side, and the arc-shaped slider 31 realizes the movement of the arc track; and the arc-shaped slider 31 will not be offset, ensuring the stability of movement. An arc rod 310 for forming sleeve products is installed on the front end face of the arc slider 31. The curvature of the arc track 312 is adapted to the curvature of the arc groove 115. The arc rod 310 can extend into the arc groove 115. Due to the arc groove 115 on the top surface of the dynamic model core 111, the movement of the arc track is achieved through the arc slider 31, so that the arc rod 310 can match the arc groove 115. When the mold is closed, the arc rod 310 can approach along the track direction of the arc groove 115 and always maintain a coaxial alignment with the arc groove 115, thereby ensuring that the wall thickness of the formed sleeve products is uniform and higher precision is ensured.

[0072] Furthermore, the curved track 312, the curved groove 313, the curved rod 310 and the curved slot 115 have the same bending diameter and are all located at the same center of a circle. Therefore, when the curved slider 31 slides along the curved track 312 through the curved groove 313, the curved rod 310 installed on the curved slider 31 moves in an arc track, and when moving, it is always coaxially aligned with the curved slot 115 on the top surface of the dynamic model core 111. After extending into the curved groove 115, it is adapted to the groove wall spacing of the curved groove 115, so that the wall thickness of the sleeve product formed is relatively uniform and the molding accuracy is relatively high; even if the curved rod 310 is away from the curved slot 115, the curved rod 310 and the curved slot 115 can remain on the same trajectory with the center of a circle.

[0073] The cam 314 is provided with a movable support member 314 at the bottom of the arc slider 31, and the movable support member 314 includes a slide support seat 328, and a slide swing block 315 capable of swinging back and forth is installed on the top of the slide support seat 328. The top of the slide swing block 315 is tilted and formed with an inclined track 316, and the bottom of the arc slider 31 is tilted and formed with an inclined slot 317 that slidably cooperates with the inclined track 316; the slide swing block 315 swings around the top of the slide support seat 328 through the shaft hole structure, and the height of the slide swing block 315 changes accordingly when it swings up and down. Therefore, the slide swing block 315 and the arc slider 31 will slide with each other through the inclined track 316 and the inclined slot 317, thereby driving the arc slider 31 to slide along the arc track 312 of the slide guide seat 311, and the arc rod 310 installed at the inner end of the arc slider 31 coaxially approaches or moves away from the arc groove 115 on the top surface of the dynamic model core 111 to realize mold closing and demolding.

[0074] Furthermore, a fixed mold fixing plate 123 is arranged below the fixed mold assembly plate 121, and support vertical plates 129 are installed on the tops of both sides of the fixed mold fixing plate 123. The fixed mold fixing plate 123 is provided with a bottom mounting groove 128 for mounting a slide support seat 328; a guide lifting cylinder 318 is arranged in the slide support seat 328, and a longitudinal moving block 319 is installed at the driving end of the guide lifting cylinder 318. The top of the longitudinal moving block 319 is rotatably connected with the slide swing block 315 through the structure of the shaft hole, and the guide lifting cylinder 318 is provided with a guide lifting cylinder 318. 18 can drive the longitudinal moving block 319 to move up and down; when the longitudinal moving block 319 rises, the sliding block 315 and the arc-shaped slider 31 will slide together through the inclined track 316 and the inclined slot 317, and the top of the sliding block 315 will slide to the position close to the bottom of the inclined slot 317; when the arc-shaped slider 31 approaches the dynamic mold core 111, the angle between the sliding block 315 and the longitudinal moving block 319 increases, so as to realize the adaptive change of the position of the arc-shaped rod 310 and realize the mold closing operation. On the contrary, when the longitudinal moving block 319 descends, the sliding block 315 and the arc-shaped slider 31 will slide together through the inclined track 316 and the inclined slot 317, and the top of the sliding block 315 will slide to the position close to the top of the inclined slot 317; when the arc-shaped slider 31 moves away from the dynamic mold core 111, the angle between the sliding block 315 and the longitudinal moving block 319 decreases, so as to realize the adaptive change of the position of the arc-shaped rod 310 and realize the demoulding.

On the contrary, when demolding, the upper mold module 1 rises and moves away from the fixed mold module, the first position guide rod 45 slides and cooperates with the first inclined guide hole 44, and the first horizontal position slide block 41 moves away from the dynamic mold core 111 along the first linear guide groove 43 to realize demolding of the horizontal slot 116.

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

[0078] Specifically, the connection 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, the first locking groove 61 and the second locking groove 62 are both formed on the outer wall of the second forming rod 52 in an arc-shaped circumference, the first locking groove 61 and the second locking groove 62 are arranged at intervals, and the first locking groove 61 and the second locking groove 62 are arranged alternately in the axial direction of the second forming rod 52, the tail end of the first locking groove 61 is axially aligned with the front end of the second locking groove 62, the first locking groove 61 and the second locking groove 62 are connected with a third locking groove 63, 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 are connected to each other to form a zigzag structure similar to "Z". The third molding rod 53 is formed with a plug-in hole 65 with a central hole structure, the inner diameter of the plug-in hole 65 is adapted to the outer diameter of the second molding rod 52 and can be inserted into the second molding rod 52; the plug-in hole 65 is formed with radially arranged elastic grooves 67, and a locking block 66 is installed in the elastic groove 67 and radially pops out into the plug-in hole 65. The locking block 66 can slide along the first locking groove 61, the second locking groove 62 and the third locking groove 63. The end of the third locking groove 63 is formed with an upward or downward locking groove 64. When the locking block 66 slides to the locking groove 64, the locking block 66 cannot continue to move laterally, and the third molding rod 53 cannot be rotated at this time, thereby ensuring the connection between the first molding rod 51 and the second molding rod 52, and preventing loosening, thereby ensuring the accuracy of the spare parts after casting.

[0079] When installing the third forming rod 53, it is inserted into the second forming rod 52, and 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 and cooperate with the first locking groove 61, and continuously push and rotate, so that the locking block 66 slides along the path of the first locking groove 61, the second locking groove 62 and the third locking groove 63 in turn, and is installed in place. At this time, the third forming rod 53 will not fall off the second forming rod 52, and a locking connection is achieved.

[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 on the outer end of the second forming rod 52, and the outer end of the second forming rod 52 is located outside the lower mold core. When the third forming rod 53 is not used, the connecting structure 6 of the second forming rod 52 will not affect the hole forming of the casting. The third forming rod 53 can have a variety of sizes, and the size of its inner hole is a fixed value. The outer diameter can be processed according to the aperture requirements of the product. Multiple sets of different third forming rods 53 are used to cooperate with the second forming rod 52. There is no need to disassemble the fixed model core 122 and the slide assembly to complete the processing of different inclined hole sizes, which not only saves time but also greatly reduces costs.
