Description

Technical Field

[0001] The present invention relates to the technical field of casting molds, and particularly to a casting mold provided with a self-positioning mechanism. Background Art

[0002] Casting molds can be used for the production and processing of some metal parts with complex shapes and different sizes, so they are widely used in fields such as automobiles and mechanical manufacturing. By reasonably designing and manufacturing casting molds, rapid and efficient production of parts can be achieved, thereby reducing production and manufacturing costs.

[0003] In the prior art, the patent with the publication number "CN105081222A" and the patent name "A Casting Mold" discloses that third threaded holes are respectively provided at the left and right ends of a protrusion, fourth threaded holes are provided at positions corresponding to the third threaded holes on the mold cover, and the mold cover and the movable mold wall are fixedly connected by a second bolt passing through the third threaded holes and the fourth threaded holes, so that the protrusion is easily stuck in a groove and positioned at the same time to prevent the mold cover from moving. The protrusion and the mold cover are fixed by bolts to prevent displacement and affect the casting quality. Fifth threaded holes are respectively provided on the top surfaces of the two side walls of the base where no card slots are provided, sixth threaded holes are provided at positions corresponding to the fifth threaded holes on the mold cover, and the mold cover and the base are fixedly connected by a third bolt passing through the fifth threaded holes and the sixth threaded holes. The base and the mold cover are fixed by bolts to prevent displacement and affect the casting quality. In addition, in the prior art, the patent with the publication number "CN101842176B" and the patent name "Casting Mold Device" discloses that a casting mold device includes a fixed mold and a movable mold. A continuously integrated frame portion is formed around the mold mating surface of the fixed mold. Stopping portions for abutting against the back surfaces of sliding cores are provided at four positions on the inner peripheral surface of the frame portion. Positioning pins are installed at the four corners of the frame portion. Positioning holes for engaging the positioning pins are formed at the four corners of the movable mold. A positioning reference seat is provided at a portion closer to the center than the positioning holes. The positioning reference seat is integrally provided with the movable mold and has the same height as the convex portion of the sliding core.

[0004] When the above-mentioned casting molds in the prior art are used, when the movable mold and the fixed mold are used for mold closing, at this time, it is necessary for the staff to manually control and adjust the position of the movable mold in order to insert the positioning pin well into the positioning hole for positioning. Adjusting and calibrating manually in this way to achieve positioning not only takes time and effort, but also is prone to errors, resulting in damage to the mold core and quality problems of the product. Therefore, we propose a casting mold provided with a self-positioning mechanism to solve the problems raised above. Summary of the Invention

[0005] The object of the present invention is to provide a casting mold provided with a self - positioning mechanism, so as to solve the problems raised in the above - mentioned background technology.

The self - locking rod is slidably connected to the bottom plate. One end of the self - locking rod close to the upper guide post is inserted into the card slot. The other end of the self - locking rod away from the upper guide post is connected to the connecting spring and the connecting rope. The connecting spring is arranged below the connecting rope, and the other end of the connecting spring is connected to the inside of the bottom plate.

[0011] Preferably, an automatic control column is installed through a slot in the middle of the bottom surface of the bottom plate. The automatic control column is arranged in a "T" shape. A reset spring is nested and connected to the outer side of the lower end of the automatic control column. The lower surface of the upper end of the automatic control column is connected to the other end of the connecting rope. The connecting rope is arranged in an "L" shape through a guide wheel.

[0012] Preferably, the vibration demoulding assembly includes a vibration plate fittingly arranged on the upper surface of the cavity. The vibration plate is arranged in an inverted "U" shape. Both the left and right sides of the vibration plate are connected to the inside of the slot opened in the upper surface of the cavity through adjusting springs.

[0013] Preferably, sliding blocks in a "7" - shaped structure are installed around the upper part of the cavity. The sliding blocks are slidably connected to the slots opened in the inner side wall of the upper connecting seat. A cross bar is rotatably installed through the inside of the sliding block. A scroll spring is nested and connected to the outer side of the cross bar. One end of the scroll spring is connected to the inside of the sliding block. The cross bar is arranged above the vibration plate. On the outer side of the end of the cross bar close to the vibration plate, beating plates are symmetrically installed. The beating plates are arranged below the vibration plate. On the outer side of the end of the cross bar close to the sliding block, a transmission gear is key - connected. A vertical plate is installed in the slot opened in the inner side wall of the upper connecting seat. A row of rack assemblies are installed at equal intervals on the side surface of the vertical plate close to the transmission gear. The transmission gear is intermittently meshed with the rack assemblies.

[0014] Preferably, the beating plates are arranged in an inclined shape. The rotation angle of the beating plates is less than 90°. The length of the beating plates is greater than the shortest distance between the cross bar and the vibration plate.

[0015] Preferably, a groove is opened in the inner part of the bottom surface of the upper connecting seat. The groove is arranged outside the cavity. A water storage frame is installed in a slot opened in the upper surface of the lower connecting seat in an embedded manner. The water storage frame is arranged outside the core. The highest point of the water storage frame is higher than the highest point of the lower connecting seat. The inside of the copper - made water storage frame is hollow. The upper part of the water storage frame is inserted into the groove. The water storage frame and the groove are arranged in a "mouth" - shaped structure with an opening on the right side. A water inlet pipe is connected through the front right side of the lower connecting seat. The rear end of the water inlet pipe is inserted into the inner part of the front side surface of the water storage frame. A drain pipe is connected through the rear left side of the lower connecting seat. The front end of the drain pipe is inserted into the inner part of the rear side surface of the water storage frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This casting mold provided with a self - positioning mechanism can enable the upper guide post to automatically insert into the corresponding lower guide sleeve to achieve self - positioning, with convenient operation, which can improve the accuracy of mold closing and avoid damage to the mold core caused by mold misalignment. The specific content is as follows:

[0017] By fitting the arc-shaped self-positioning groove with the anti-displacement mechanism and moving downward, the descent of the upper mounting plate and the upper connecting seat can be self-positioned. In the later stage, there is no need to repeatedly adjust the position of the upper connecting seat, and the upper guide post can be automatically inserted into the corresponding lower guide sleeve for self-positioning. The operation is convenient, so the positioning operation can be completed in a short time. This not only improves the accuracy of mold closing, avoids defects such as dimensional deviation, flash or burrs in the casting and damage to the mold core caused by mold misalignment, but also reduces the manual operation time and labor intensity, improves production efficiency, and greatly shortens the production cycle.

[0018] When the entire casting mold is turned over for pouring, the reset spring automatically drives the automatic control column to move outward and reset by its stored energy, so that the automatic control column loses the pulling force on the connecting rope, and then the self-locking rod automatically moves outward under the action of the stored energy of the connecting spring. By inserting the self-locking rod into the corresponding card slot, the upper connecting seat and the lower connecting seat can be stably closed without manual operation.

[0019] Furthermore, when the casting mold is reversed and reset later, by squeezing the automatic control column, the automatic control column moves upward to pull the connecting rope, so that the self-locking rod is separated from the card slot, and thus the locking of the upper connecting seat and the lower connecting seat can be automatically released, facilitating mold opening later.

[0020] When the upper connecting seat moves upward to open the mold, the cavity moves downward under its own gravity, and then drives the drive gear to intermittently engage with the rack assembly, so that the flapper intermittently drives the vibrating plate to knock and beat the cavity, applying a vibration effect to the cavity and assisting the cavity to demold.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1-13 , the present invention provides the following technical solutions:

[0037] Embodiment 1: The casting mold provided with a self-positioning mechanism in this embodiment can automatically perform positioning during the mold closing process, thereby ensuring the accuracy of mold closing, avoiding damage to the mold core, and being convenient to operate. The specific structure refers to the attached Figures 1-8As shown in the figure, it includes an upper mounting plate 1 and an upper connecting seat 5 mounted on the lower surface of the upper mounting plate 1. A cavity 12 is installed inside the upper connecting seat 5. Self-positioning grooves 2 are symmetrically opened on both left and right sides of the upper mounting plate 1. Upper guide posts 3 are installed at the four corners of the lower surface of the upper mounting plate 1. A lower connecting seat 6 is attached to the bottom surface of the upper connecting seat 5. A bottom plate 7 is fixed to the bottom surface of the lower connecting seat 6. An anti-misalignment mechanism 8 is fixed above the left side of the bottom plate 7. A core 13 is installed inside the upper part of the lower connecting seat 6. The anti-misalignment mechanism 8 is in close contact with the left self-positioning groove 2. Lower guide sleeves 4 are fixed at the four corners of the upper surface of the bottom plate 7. The lower ends of the upper guide posts 3 penetrate through the lower guide sleeves 4 and are inserted into the grooves inside the bottom plate 7. A locking assembly for fixing the upper guide posts 3 is installed inside the bottom plate 7. A vibration demoulding assembly for assisting demoulding is installed on the upper surface of the cavity 12. Both the self-positioning groove 2 and the anti-misalignment mechanism 8 are arc-shaped.

[0038] A core 13 is arranged directly below the cavity 12. An upper casting diversion plate 121 is embedded and installed inside the lower right surface of the cavity 12. The lowest point of the cavity 12 and the lowest point of the upper casting diversion plate 121 are on the same horizontal plane. A lower casting diversion plate 131 is embedded and fixed inside the upper right surface of the core 13. The highest point of the right side of the core 13 and the highest point of the lower casting diversion plate 131 are on the same horizontal plane. The upper casting diversion plate 121 is in close contact with the upper part of the lower casting diversion plate 131. The upper casting diversion plate 121 and the lower casting diversion plate 131 form an annular structure. The space inside the upper casting diversion plate 121 is connected to the space inside the cavity 12. The space inside the lower casting diversion plate 131 is connected to the space inside the core 13. A card slot 301 is opened inside the lower end of the upper guide post 3. The inside of the lower guide sleeve 4 is hollow. The locking assembly includes a self-locking rod 15, a connecting spring 151 and a connecting rope 152 installed in the groove opened inside the bottom plate 7. The self-locking rod 15 is slidably connected to the bottom plate 7. One end of the self-locking rod 15 close to the upper guide post 3 is inserted into the card slot 301. A connecting spring 151 and a connecting rope 152 are connected to the other end of the self-locking rod 15 far from the upper guide post 3. The connecting rope 152 is arranged below the connecting spring 151. The other end of the connecting spring 151 is connected to the inside of the bottom plate 7. An automatic control column 11 is installed through the groove opened in the middle of the bottom surface of the bottom plate 7. The automatic control column 11 is arranged in a "T" shape structure. A return spring 111 is nested and connected to the outer side of the lower end of the automatic control column 11. The lower surface of the upper end of the automatic control column 11 is connected to the other end of the connecting rope 152. The connecting rope 152 is arranged in an "L" shape through a guide wheel.

[0039] First, move the entire casting mold into the working area. After reaching the working area, the staff manually lift the upper mounting plate 1, and make the self-aligning groove 2 on the left side of the upper mounting plate 1 fit and contact with the right side of the anti-misalignment mechanism 8. At this time, the upper connecting seat 5 below the upper mounting plate 1 can be self-positioned with the lower connecting seat 6. Then, keep the self-aligning groove 2 on the left side of the upper mounting plate 1 in contact with the anti-misalignment mechanism 8 and move downward. When the upper mounting plate 1 descends to a certain position, the lower end of the upper guide post 3 just inserts into the corresponding lower guide sleeve 4, so as to achieve self-positioning. There is no need for the staff to repeatedly adjust the placement position of the upper mounting plate 1 for positioning adjustment, and the operation is convenient. At this time, the upper connecting seat 5 and the lower connecting seat 6 are closely fitted, and the upper pouring guide plate 121 and the lower pouring guide plate 131, both of which are arc-shaped structures, are closely fitted. The upper pouring guide plate 121 and the lower pouring guide plate 131 form a complete circular ring structure.

[0040] Then continue to apply a downward pressure on the upper mounting plate 1, and then turn the entire casting mold upward by 90°. As shown in the attachment Figure 13 At this time, the reset spring 111 automatically drives the automatic control column 11 to move outward by its stored energy. At this time, the automatic control column 11 does not generate a certain pulling force on the connecting rope 152. Then, the connecting spring 151 drives the self-locking rod 15 to move outward automatically by its stored energy. At this time, one end of the self-locking rod 15 inserts into the corresponding card slot 301, so that the lower end of the upper guide post 3 is stably connected to the bottom plate 7, thereby improving the stability of the casting mold during mold closing, and there is no need to manually lock the casting mold after mold closing.

[0041] Then the openings of the upper pouring guide plate 121 and the lower pouring guide plate 131 face upward, and then the liquid can be poured into the cavity 12 and the core 13 through the upper pouring guide plate 121 and the lower pouring guide plate 131. After a period of time, the castings in the cavity 12 and the core 13 are formed. At this time, in the same way as described above, rotate the entire casting mold reversely by 90° again, so that the casting mold is placed as shown in the attachment Figure 1 At this time, the bottom plate 7 contacts the ground of the working area, and the ground will squeeze the automatic control column 11 inside the bottom surface of the bottom plate 7 to move upward, so that the automatic control column 11 completely enters the bottom plate 7, and the reset spring 111 stores energy. At this time, the upper end of the automatic control column 11 will simultaneously pull one end of the four groups of connecting ropes 152, the other end of the connecting rope 152 pulls the self-locking rod 15, and the connecting spring 151 stores energy, so that the self-locking rod 15 is separated from the card slot 301, and then the locking work of the locking component can be automatically released without manual operation.

[0042] Then move the upper mounting plate 1 upward. At this time, the upper mounting plate 1 drives the cavity 12 to move upward together for demolding operation. At the same time, the upper guide post 3 is separated from the lower guide sleeve 4, thus completing the entire casting operation.

[0043] Example 2: The casting mold with a self-positioning mechanism in this example, for its specific structure, refer to the attached Figures 9-13 As shown in the figure, the vibration demolding assembly includes a vibration plate 16 fittingly arranged on the upper surface of the cavity 12. The vibration plate 16 is arranged in an inverted "U" shape structure. Both lower sides of the left and right sides of the vibration plate 16 are connected to the inside of the groove opened inside the upper surface of the cavity 12 through adjusting springs 161. Sliding blocks 17 in a "7" - shaped structure are installed around the upper part of the cavity 12. The sliding blocks 17 are slidably connected to the grooves opened on the inner side walls of the upper connecting seat 5. A cross bar 18 is rotatably installed through the inside of the sliding block 17. A scroll spring 183 is nested and connected to the outer side of the cross bar 18. One end of the scroll spring 183 is connected to the inside of the sliding block 17. The cross bar 18 is arranged above the vibration plate 16. Flapping plates 182 are symmetrically installed on the outer side of one end of the cross bar 18 close to the vibration plate 16. The flapping plates 182 are arranged below the vibration plate 16. A transmission gear 181 is key - connected to the outer side of one end of the cross bar 18 close to the sliding block 17. A vertical plate 19 is installed in the groove opened on the inner side wall of the upper connecting seat 5. A row of rack assemblies 191 are equidistantly installed on one side surface of the vertical plate 19 close to the transmission gear 181. The transmission gear 181 is intermittently meshed with the rack assemblies 191. The flapping plates 182 are arranged in an inclined shape, the rotation angle of the flapping plates 182 is less than 90°, and the length of the flapping plates 182 is greater than the shortest distance between the cross bar 18 and the vibration plate 16.

[0044] On the basis of Example 1, a knocking vibration force can be applied to the cavity 12 through the vibration demolding assembly, enabling the cavity 12 to quickly perform demolding operations. When the upper connecting seat 5 drives the cavity 12 to move upward for demolding, at this time, the cavity 12 will move downward due to its own gravity. At this time, the sliding blocks 17 around the upper part of the cavity 12 slide in the grooves opened on the inner wall of the upper connecting seat 5. At this time, the sliding blocks 17 drive the cross bar 18 to move together. When the transmission gear 181 on the outer side of the cross bar 18 moves to the position where it meshes with the multiple groups of rack assemblies 191 equidistantly installed on the outer side of the vertical plate 19, it drives the transmission gear 181 and the cross bar 18 to automatically rotate. At this time, the scroll spring 183 stores energy. The cross bar 18 drives the two flapping plates 182 to rotate, so that one of the flapping plates 182 applies a downward pressure to the vibration plate 16. At this time, the adjusting spring 161 stores energy, and then the vibration plate 16 applies a knocking vibration force to the cavity 12. When the transmission gear 181 moves to the position where it is not meshed with the rack assemblies 191, through the energy stored in the scroll spring 183, it drives the cross bar 18 to rotate in the reverse direction and reset. By operating in this way repeatedly, the cross bar 18 rotates forward and backward reciprocally, so that the vibration plate 16 reciprocally applies a knocking vibration force to the cavity 12, facilitating the quick demolding operation of the cavity 12.

[0045] Example 3: The casting mold with a self - positioning mechanism in this example, for its specific structure, refer to the attachedFigures 3-4 As shown, a groove 51 is formed inside the bottom surface of the upper connecting seat 5. The groove 51 is arranged outside the cavity 12. A water storage frame 14 is installed in a groove formed inside the upper surface of the lower connecting seat 6. The water storage frame 14 is arranged outside the core 13. The highest point of the water storage frame 14 is higher than the highest point of the lower connecting seat 6. The inside of the copper water storage frame 14 is hollow. The upper part of the water storage frame 14 is inserted into the groove 51. The water storage frame 14 and the groove 51 are arranged in a "mouth" - shaped structure with an opening on the right side. A water inlet pipe 9 is connected through the front right side of the lower connecting seat 6. The rear end of the water inlet pipe 9 is inserted into the front side surface inside the water storage frame 14. A drain pipe 10 is connected through the rear left side of the lower connecting seat 6. The front end of the drain pipe 10 is inserted into the rear side surface inside the water storage frame 14. On the basis of Embodiment 1, it is convenient to preheat and cool - form the cavity 12 and the core 13 in the casting mold. When preheating the casting mold is required in the early stage to increase the temperature of the mold and prevent defects in the casting caused by the metal liquid cooling too fast during pouring, or when cooling and solidifying the casting mold is required after pouring, when the upper connecting seat 5 and the lower connecting seat 6 are closely attached, at this time, the upper end of the water storage frame 14 is inserted into the groove 51. Then, heating liquid or cooling liquid can be injected into the hollow - structured water storage frame 14 from the water inlet pipe 9, so that the heating liquid or cooling liquid in the water storage frame 14 can heat or cool the cavity 12 and the core 13 well. Later, the heating liquid or cooling liquid in the water storage frame 14 can be discharged from the drain pipe 10 for replacement.
