Description

Technical Field

[0001] The present application relates to the technical field of casting equipment, and particularly relates to a mold facilitating the removal of a sprue. Background Art

[0002] During metal casting production, molten metal processing materials are usually injected into the molding cavity of a mold through a runner, and then cooled. The processing materials cool and solidify inside the molding cavity of the mold to obtain a formed workpiece, and finally the workpiece is demolded to complete the casting production.

[0003] During the above-mentioned casting production, sprue (commonly known as a sprue) will inevitably be generated in the runner of the mold. In subsequent processing, the sprue needs to be machined and cut separately, which increases the processes of workpiece production and causes inconvenience to metal production. Utility Model Content

[0004] In order to facilitate metal processing, the present application provides a mold facilitating the removal of a sprue.

[0005] A mold facilitating the removal of a sprue provided by the present application adopts the following technical solutions:

[0006] A mold facilitating the removal of a sprue includes a bracket, a lower mold, a first upper mold, a second upper mold, and a demolding mechanism; the lower mold is fixedly arranged on the bracket; the first upper mold and the second upper mold are both detachably arranged on the lower mold, and a molding cavity for workpiece forming is formed between the first upper mold and the lower mold; a runner is formed between the second upper mold and the lower mold; the demolding mechanism is arranged on the bracket and is used for demolding the workpiece and the sprue successively.

[0007] By adopting the above technical solutions, during casting production, an operator injects molten metal processing materials into the molding cavity through the runner, and then cools to obtain a formed workpiece and a sprue. Finally, the demolding assembly is used to demold the workpiece and the sprue successively, without the need to additionally increase processes to cut the sprue, optimizing the processing technology of casting production and improving the convenience of metal production.

[0008] Optionally, the demolding mechanism includes a first push block, a second push block, and a driving assembly; the first push block and the second push block are both slidably arranged on the bracket, and the first push block and the second push block are detachably connected; the driving assembly is arranged on the bracket and is used to drive the second push block to slide; a first transmission assembly is arranged on the first push block, and the first transmission assembly is used to transmit the sliding of the second push block to the workpiece and drive the workpiece to be demolded; a second transmission assembly is arranged on the second push block, and the second transmission assembly is used to transmit the sliding of the second push block to the sprue and drive the sprue to be demolded.

[0009] By adopting the above technical solution, after the material handle and the workpiece are cast and produced, the operator first disassembles the first upper mold, and then uses the driving component to drive the second push block to slide towards the lower mold. The first transmission component transmits the sliding of the second push block to the workpiece and drives the workpiece to slide relative to the material handle, and the two are separated, and the workpiece is demolded; then the operator disassembles the second upper mold and uses the driving component to drive the second push block to slide towards the lower mold again. The second transmission component transmits the sliding of the second push block to the material handle and drives the material handle to be demolded, thereby realizing the demolding of the workpiece and the material handle successively.

[0010] Optionally, a first counterbore is provided at one end of the first push block close to the second push block; the first transmission component includes a first support column and a first limit block; one end of the first support column is inserted into the lower mold and is located in the molding cavity; the first limit block is located in the first counterbore, and the end of the first support column away from the lower mold is inserted into the first push block and is fixedly connected to the first limit block.

[0011] By adopting the above technical solution, when the operator uses the driving component to drive the second push block to slide towards the lower mold, the second push block pushes the first limit block and the first support column to slide towards the lower mold. Under the action of the first support column, the demolding of the workpiece is completed. Since the second upper mold is fixed on the lower mold at this time, the material handle will not move, so that the workpiece slides relative to the material handle, and under the action of the shearing force, the workpiece is separated from the material handle and demolded first.

[0012] Optionally, a second counterbore is provided at one end of the first push block close to the second push block; the second transmission component includes a second support column, a second limit block, a third limit block, a third support column and a third push block; one end of the second support column is inserted into the lower mold and is located in the runner; the second limit block is located in the second counterbore, and the end of the second support column away from the lower mold is inserted into the first push block and is fixedly connected to the second limit block; a chute is provided on one side of the second push block close to the first push block, and the chute is disposed opposite to the second counterbore; the third limit block is slidably disposed in the chute and is connected to the second limit block; the third support column is inserted into the second push block and is fixedly connected to the third limit block; the third push block is located on the side of the second push block away from the first push block, and the third push block is detachably connected to the second push block; the end of the third support column away from the third limit block abuts against the third push block.

[0013] By adopting the above technical solution, after the workpiece is demoulded, the operator fixedly connects the third push block and the second push block, and then uses the driving component to drive the second push block to move again, thereby driving the third push block, the third support column, the third limit block, the second limit block and the second support column to slide towards the lower die, so that the stock bar moves away from the lower die for demoulding.

[0015] By adopting the above technical solution, the hydraulic cylinder is used to drive the connecting block to slide, thereby realizing driving the second push block to slide.

[0016] Optionally, a first threaded hole is formed on one side of the first push block close to the second push block; a third counterbore is formed on the second push block, and the third counterbore is arranged opposite to the first threaded hole.

[0017] By adopting the above technical solution, the detachable connection between the first push block and the second push block is realized by using bolts inserted into the first threaded hole and the third counterbore, and the first limit block is clamped between the first push block and the second push block. Compared with fixing the first limit block and the first support column on the second push block, if the first support column is worn out during use, the first limit block and the first support column can be conveniently replaced, thus facilitating metal processing.

[0018] Optionally, a second threaded hole is formed on one side of the second push block close to the third push block; a fourth counterbore is formed on the third push block, and the fourth counterbore is arranged opposite to the second threaded hole.

[0019] By adopting the above technical solution, the detachable connection between the second push block and the third push block is realized by using bolts inserted into the second threaded hole and the fourth counterbore, which can facilitate the installation of the third push block during stock bar demoulding, with simple operation, thus facilitating metal processing, and cooperating with the first threaded hole and the third counterbore, so that any component of the whole device can be conveniently disassembled and replaced in case of damage.

[0035] The following will further elaborate on this application in conjunction with the attached Figures 1-4 drawings.

[0036] An embodiment of this application discloses a mold facilitating the removal of the sprue. Referring to Figure 1 , the mold facilitating the removal of the sprue includes a bracket 1, a lower mold 11, a first upper mold 12, a second upper mold 13, and a stripping mechanism 2. The bracket 1 consists of a horizontally placed bottom plate and a vertical plate fixedly mounted on the bottom plate.

[0037] Referring to Figure 1 and Figure 2 , the lower mold 11 is fixedly arranged on the bracket 1, and both the first upper mold 12 and the second upper mold 13 are detachably connected to the lower mold 11 by bolts. A forming cavity 111 for workpiece forming is formed between the first upper mold 12 and the lower mold 11. A runner 112 is formed between the second upper mold 13 and the lower mold 11, and the runner 112 is located at the top of the forming cavity 111 and is in communication with the forming cavity 111. The stripping mechanism 2 is arranged on the bracket 1 and is used for stripping the workpiece and the sprue successively.

[0038] During casting production, the operator injects the molten metal processing material into the forming cavity 111 through the runner 112, then cools it to obtain the formed workpiece and sprue, and finally uses the stripping assembly to strip the workpiece and the sprue successively, and the casting production is completed.

[0039] The stripping mechanism 2 includes a first push block 21, a second push block 22, a third push block 255, a driving assembly 23, a first transmission assembly 24, and a second transmission assembly 25.

[0040] Referring to Figure 2 and Figure 3 , the first push block 21, the second push block 22, and the third push block 255 are all slidably arranged on the bracket 1, and the sliding direction is along the direction of approaching or departing from the lower mold 11. The first push block 21 is located on the side of the second push block 22 closer to the lower mold 11. Two first threaded holes 213 are formed on the side of the first push block 21 closer to the second push block 22. Two third counterbored holes 222 are formed on the second push block 22, and the third counterbored holes 222 correspond to the first threaded holes 213 one by one and are arranged opposite to the first threaded holes 213. The first push block 21 and the second push block 22 are detachably connected by bolts passing through the third counterbored holes 222 and the first threaded holes 213.

[0041] The third pushing block 255 is located on the side of the second pushing block 22 away from the first pushing block 21. Two second threaded holes 223 are formed on the side of the second pushing block 22 close to the third pushing block 255. Two fourth counterbores 2551 are formed on the third pushing block 255. The fourth counterbores 2551 correspond to the second threaded holes 223 one by one, and the fourth counterbores 2551 are arranged opposite to the second threaded holes 223. The second pushing block 22 and the third pushing block 255 are detachably connected by bolts passing through the fourth counterbores 2551 and the second threaded holes 223.

[0042] Referring to Figure 1 , the driving assembly 23 is arranged on the bracket 1. There are two sets of driving assemblies 23, which are respectively located on both sides of the second pushing block 22. The driving assembly 23 includes a hydraulic cylinder 231 and a connecting block 232. The fixed end of the hydraulic cylinder 231 is fixedly arranged on the bracket 1. The connecting block 232 is fixedly arranged on the movable end of the hydraulic cylinder 231, and the connecting block 232 is fixedly connected to the second pushing block 22.

[0043] Referring to Figure 4 , two first counterbores 211 are formed at one end of the first pushing block 21 close to the second pushing block 22. The first transmission assembly 24 corresponds to the first counterbores 211 one by one. The first transmission assembly 24 includes a first support column 241 and a first limiting block 242. The first support column 241 passes through the bracket 1, and one end of the first support column 241 passes through the first pushing block 21, and the other end passes through the lower mold 11 and is located in the molding cavity 111. The first limiting block 242 is located in the first counterbore 211 and is fixedly connected to the first support column 241 coaxially.

[0044] Referring to Figure 2 and Figure 3 , two second counterbores 212 are formed on one side wall of the first pushing block 21 close to the second pushing block 22. The second transmission assembly 25 corresponds to the second counterbores 212 one by one. The second transmission assembly 25 includes a second support column 251, a second limiting block 252, a third support column 254 and a third limiting block 253. The second support column 251 passes through the bracket 1, and one end of the second support column 251 passes through the first pushing block 21, and the other end passes through the lower mold 11 and is located in the runner 112. The second limiting block 252 is located in the second counterbore 212 and is fixedly connected to the second support column 251 coaxially.

[0045] On one side wall of the second pushing block 22 close to the first pushing block 21, two sliding grooves 221 are formed. The sliding grooves 221 correspond to the second counterbores 212 one by one, and the sliding grooves 221 are arranged opposite to the second counterbores 212. The third support column 254 is inserted through the second pushing block 22, and one end of the third support column 254 abuts against the second pushing block 22. The third limiting block 253 is slidably arranged in the sliding groove 221, and the third limiting block 253 is fixedly connected to one end of the third support column 254 away from the third pushing block 255. A fixing pin 2531 is coaxially and fixedly arranged on the third limiting block 253, and an external thread is arranged on the fixing pin 2531. A pin hole 2521 is coaxially formed in the second limiting block 252, an internal thread is arranged in the pin hole 2521, and the internal thread in the pin hole 2521 is adapted to the external thread on the fixing pin 2531. The third limiting block 253 and the second limiting block 252 are detachably connected through the fixing pin 2531 and the pin hole 2521.

[0046] The implementation principle of a mold for facilitating the removal of a handle in an embodiment of the present application is as follows:

[0047] When demolding the workpiece and the handle after casting is completed, the operator first disassembles the first upper mold 12 through bolts, then fixes the second limiting block 252 and the third limiting block 253 by using the fixing pin 2531 and the pin hole 2521, and then fixes the first pushing block 21 and the second pushing block 22 by using bolts. Then the operator starts the hydraulic cylinder 231 to contract. The hydraulic cylinder 231 drives the second pushing block 22 to move towards the lower mold 11 through the connecting block 232. Since the first pushing block 21 and the second pushing block 22 are fixed at this time, and the first limiting block 242 abuts against the second pushing block 22, when the second pushing block 22 moves, it drives the first pushing block 21, the first limiting block 242 and the first support column 241 to slide towards the lower mold 11. Under the action of the first support column 241, the workpiece moves away from the lower mold 11 to be demolded. Since the second upper mold 13 is fixed on the lower mold 11 at this time, the handle will not move, so that the workpiece and the handle generate relative sliding. Under the action of the shearing force, the workpiece is separated from the handle and demolded first.

[0048] During the demolding process of the workpiece, since the third limiting block 253 is located in the sliding groove 221, when the second pushing block 22 slides towards the lower mold 11, there is an idle stroke in the sliding groove 221, so the second support column 251 will not be driven to slide.

[0049] After the workpiece is demolded, the operator drives the hydraulic cylinder 231 to extend and reset, thereby driving the first push block 21 and the second push block 22 to slide away from the lower mold 11. At this time, the end of the second push block 22 close to the third push block 255 is flush with the end of the third support column 254 close to the third push block 255. Then the operator fixes the second push block 22 and the third push block 255 with bolts. The operator then disassembles the second upper mold 13 with bolts and starts the hydraulic cylinder 231. The hydraulic cylinder 231 drives the second push block 22, the first push block 21 and the third push block 255 to slide together towards the lower mold 11. At this time, the third push block 255 abuts against the third support column 254. The third push block 255 drives the third support column 254, the third limit block 253, the second limit block 252, and the second support column 251 to slide towards the lower mold 11. Under the action of the second support column 251, the sprue moves away from the lower mold 11 to be demolded, completing the demolding of the sprue, and subsequent casting production can be carried out.

[0050] The above are all the preferred embodiments of this application. Without limiting the protection scope of this application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
