Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold which can determine the starting position of a product screw thread. Background Art

[0002] At present, workers often use molds to make products to meet product production requirements, such as making screw threads on the surface of products. However, when the screw thread making parts in conventional molds rotate on the product surface to make screw threads, since most of the screw thread making parts are not limited to a predetermined rotation distance, the rotation distance of the screw thread making parts may be too large or too small, which may easily lead to the final screw thread starting position formed on the product surface being inconsistent with the predetermined screw thread starting position. As a result, the final forming length of the screw thread may be too long or too short, which does not meet the product production requirements.

[0003] In addition, even if the starting position of the screw thread on the product surface is consistent with the predetermined starting position of the screw thread, it cannot be determined that the number of screw thread layers formed on the product surface can meet the predetermined number of layers. When the number of screw thread layers formed on the product surface is lower than the predetermined number of layers, the tightness of the connection of the product may be affected. Similarly, when the number of screw thread layers formed on the product surface is higher than the predetermined number of layers, it means that the wear between the screw thread production component and the product will increase additionally, thereby shortening the service life of the screw thread production component.

[0028] refer to Figures 1 to 6 According to a preferred embodiment of the present invention, a mold capable of determining a starting position of a product thread will be described in detail below. The mold capable of determining a starting position of a product thread includes a mold body 10, a thread making component 20 and a limiting component 30.

[0029] The mold body 10 forms a molding cavity 101, and the molding cavity 101 is used to make at least one product 90. The screw thread making component 20 is disposed on the mold body 10, and is used to make screw threads on the surface of the product 90 in the molding cavity 101. The limiting component 30 is used to limit the starting position of the screw threads made by the screw thread making component 20 on the surface of the product 90.

[0030] Preferably, the screw thread making assembly 20 includes a driving unit 21, at least one screw thread forming member 22, and the same number of guide members 23 as the screw thread forming members 22, wherein the driving unit 21 is disposed on the mold body 10. Each of the screw thread forming members 22 is disposed in the forming cavity 101 of the mold body 10, and each of the screw thread forming members 22 is driven and rotatably mounted on the driving unit 21. In addition, each of the screw thread forming members 22 is provided with a screw thread forming portion 221 at one end thereof for forming screw threads on the surface of the product 90. Each of the guide members 23 is installed on the inner wall forming the forming cavity 101, and each of the guide members 23 is threadedly connected to a screw thread forming member 22, and each of the screw thread forming members 22 is driven by the driving unit 21 to move along the axial direction of the correspondingly connected guide member 23, so that the screw thread forming portion 221 of each screw thread forming member 22 can approach the product 90, so that the surface of the product 90 can be screw-threaded by the screw thread forming member 22.

[0031] It can be understood that when the mold capable of determining the starting position of the product screw thread needs to make screw threads on the surface of the product 90, the driving unit 21 is activated to drive the screw thread forming member 22 to rotate, so that the screw thread forming portion 221 of the screw thread forming member 22 is driven to move along the axial direction of the guide member 23 to approach the surface of the product 90, thereby making screw threads. Accordingly, after the screw thread forming member 22 has made screw threads on the surface of the product 90, the driving unit 21 is activated to drive the screw thread forming member 22 to move along the axial direction of the guide member 23, so that the screw thread forming portion 221 of the screw thread forming member 22 is away from the product 90.

[0032] Preferably, the driving unit 21 includes a driving member 211 and a transmission member 212, and preferably, the driving member 211 is installed on the mold body 10. The transmission member 212 includes a driving member 2121, a transmission member 2122, a passive member 2123 and a transmitted member 2124, wherein the driving member 2121 is driven and rotatably installed on the driving end of the driving member 211. The transmission member 2122 is rotatably engaged with the driving member 2121 and the passive member 2123, and the transmission member 2122 drives the passive member 2123 to rotate when the driving member 211 drives the driving member 2121 to rotate. The transmitted part 2124 is installed on the screw thread forming part 22, and the transmitted part 2124 is also meshed with the end of the passive part 2123 away from the transmission part 2122, and the transmitted part 2124 can be driven by the passive part 2123 to rotate when the transmission part 2122 drives the passive part 2123 to rotate. Therefore, when the driving member 211 drives the driving member 2121 to rotate, the transmission member 2122 is driven to drive the passive part 2123 to rotate, thereby causing the transmitted part 2124 to be driven to rotate, so that the screw thread forming part 22 on which the transmitted part 2124 is installed is driven to rotate, so that the screw thread forming portion 221 of the screw thread forming part 22 can produce screw threads on the surface of the product 90.

[0033] Preferably, the driving member 211 is implemented as a hydraulic motor. The driving member 2121, the passive member 2123 and the transmitted member 2124 are all implemented as a gear. The transmission member 2122 is implemented as a chain. The guide member 23 is implemented as a threaded sleeve.

[0034] The limiting assembly 30 includes a first limiting member 31 and at least one second limiting member 32, wherein the first limiting member 31 is used to limit the moving distance of the end of the screw thread forming member 22 provided with the screw thread forming portion 221. The second limiting member 32 is used to limit the moving distance of the end of the screw thread forming member 22 not provided with the screw thread forming portion 221, so that the screw thread forming member 22 can move back and forth along the axial direction of the correspondingly connected guide member 23 for a predetermined distance and then stop.

[0035] The first limiting member 31 includes a first stopper 311 and a first limiting member 312, wherein the first stopper 311 and the first limiting member 312 are adjacently and spaced apart from each other in the molding cavity 101, and the first stopper 311 is installed on the screw thread forming member 22 and close to the end of the screw thread forming portion 221, and can approach and move away from the first limiting member 312 when the driving unit 21 drives the screw thread forming member 22. The first limiting member 312 is installed on the guide member 23, and the first limiting member 312 extends a predetermined length in a direction close to the first stopper 311 to form a first limiting portion 3121, and the first limiting portion 3121 can abut against the first stopper 311 when the screw thread forming member 22 drives the first stopper 311 to move over a predetermined distance, thereby stopping the rotation of the screw thread forming member 22.

[0036] Those skilled in the art can understand that, when the driving unit 21 drives the screw thread forming part 22 to rotate the screw thread forming part 22 along the axial direction of the guide member 23, the first stop block 311 installed on the screw thread forming part 22 is driven to move along the axial direction of the screw thread forming part 22 until the first stop block 311 can be located on the same radial surface of the screw thread forming part 22 as the first limiting portion 3121 of the first limiting member 312. At this time, the first stop block 311 is driven to abut against the first limiting portion 3121 of the first limiting member 312. Due to the limiting effect of the first limiting portion 3121, the first stop block 311 no longer continues to move along the axial direction of the screw thread forming part 22, thereby causing the screw thread forming portion 221 of the screw thread forming part 22 to stop forming screw threads.

[0037] In one embodiment, each of the thread forming members 22 integrally extends outward from the middle portion along the radial direction by a predetermined length to form a threaded portion 222 for threaded connection with the guide member 23. The first stopper 311 is installed on one side of the threaded portion 222 close to the thread forming portion 221.

[0038] Each of the second limiting members 32 includes a second stopper 321 and a second limiting part 322, wherein the second stopper 321 and the second limiting part 322 are adjacently and spaced apart from each other in the molding cavity 101, and the second stopper 321 is installed at the end of the screw thread forming part 22 and away from the screw thread forming portion 221, and can approach and move away from the second limiting part 322 when the driving unit 21 drives the screw thread forming part 22. The second limiting part 322 extends a predetermined length in a direction close to the second stopper 321 to form a second limiting part 3221, and the second limiting part 3221 can abut against the second stopper 321 when the screw thread forming part 22 drives the second stopper 321 to move a predetermined distance, thereby stopping the rotation of the screw thread forming part 22.

[0039] It can be understood that when the driving unit 21 drives the screw thread forming part 22 to rotate the screw thread forming part 22 along the axial direction of the guide member 23, the second stop block 321 installed on the screw thread forming part 22 is driven to move along the axial direction of the screw thread forming part 22 until the second stop block 321 can be located on the same radial surface of the screw thread forming part 22 as the second limiting portion 3221 of the second limiting member 322. At this time, the second stop block 321 is driven to abut against the second limiting portion 3221 of the second limiting member 322. Due to the limiting effect of the second limiting portion 3221, the second stop block 321 no longer continues to move along the axial direction of the screw thread forming part 22. In this way, the screw thread forming portion 221 of the screw thread forming part 22 is away from the product 90.

[0040] In one embodiment, the end of the screw thread forming member 22 away from the screw thread forming portion 221 is integrally recessed inwardly along the radial direction to form two steps and a tube portion arranged between the two steps. Correspondingly, the second limiting member 322 also has two locking portions 3222, and the two locking portions 3222 are arranged at intervals to form an opening, and the size of the opening is adapted to the size of the tube portion. In addition, when the driving unit 21 drives the screw thread forming member 22 to move, the tube portion moves between the two locking portions 3222, and the two locking portions 3222 can abut against one of the steps when the tube portion moves a predetermined distance, thereby preventing the screw thread forming member 22 from continuing to move, thereby limiting the distance that the screw thread forming member 22 moves along the axial direction of the guide member 23.

[0041] It is worth noting that the number of the second limiting members 32 corresponds to the number of the screw thread forming members 22. Therefore, in one embodiment, the number of the screw thread forming members 22 is set to two, and correspondingly, the number of the second limiting members 32 is set to two.

[0042] Preferably, the second stopper 322 is recessed from the middle portion along the axial direction of the screw thread forming member 22 by a predetermined distance to form a groove 32201, the size of the groove 32201 is adapted to the size of the screw thread forming member 22, and the second stopper 3221 is formed in the groove 32201, so that when the driving unit 21 drives the screw thread forming member 22, the second stopper 321 can be driven by the screw thread forming member 22 and abut against the second stopper 3221 in the groove 32201, thereby increasing the moving distance of the screw thread forming member 22. In other words, after the screw thread forming portion 221 of the screw thread forming member 22 forms the screw thread of the product 90, it can be farther away from the product 90, so that the product 90 can be removed more conveniently.

[0043] Preferably, the second stopper 322 further forms a plurality of connection holes 32202, each of which is evenly arranged on the same side of the second stopper 322, for connecting a fixing component, so that the second stopper 322 is fixedly connected to the inner wall forming the molding cavity 101. Preferably, each of the connection holes 32202 is implemented as a threaded hole to facilitate disassembly and connection.

[0044] In this way, when the driving unit 21 is started to drive the screw thread forming part 22 to move, the first limiting member 31 and the second limiting member 32 can respectively prevent the screw thread forming part 22 from continuing to move when the screw thread forming part 22 moves a predetermined distance, so that the two ends of the screw thread forming part 22 can move to the predetermined position and then stop, thereby making the starting position of the screw thread on the surface of the product 90 unique.

[0045] Preferably, the mold body 10 includes a first body 11 and a second body 12, wherein the first body 11 and the second body 12 are arranged opposite to each other, and the first body 11 is detachably connected to the second body 12 to form the mold body 10, and the first body 11 has a first cavity, and correspondingly, the second body 12 has a second cavity, and the first cavity and the second cavity can form the molding cavity 101 when the first body 11 and the second body 12 are connected, for molding the screw thread of the product 90.

One end of the passive member 2123 is arranged in the channel of the second body 12, and the other end of the passive member 2123 is arranged in the second cavity of the second body 12. The transmitted member 2124, the screw thread forming member 22 and the guide member 23 are all arranged in the second cavity of the second body 12, wherein the guide member 23 is fixedly installed on the inner wall forming the second cavity.

[0048] Correspondingly, the first stopper 311 and the first stopper 312 of the first stopper member 31 and the second stopper 321 and the second stopper 322 of the second stopper member 32 are all arranged in the second cavity of the second body 12, wherein the second stopper 322 is fixedly connected to the inner wall forming the second cavity.

[0049] Preferably, the mold that can determine the starting position of the product thread also includes a plurality of guide components 40, and the guide components 40 are used to determine the movement direction of the first body 11 and the second body 12 to separate and connect, so that the first body 11 and the second body 12 can extrude the product 90 when the first body 11 and the second body 12 move relative to each other.

[0050] Preferably, each of the guide components 40 includes a first positioning member 41, a second positioning member 42 and a guide member 43, wherein the guide member 43 extends from one end to the other end to form a first guide slot 4301 and a second guide slot 4302, respectively, and the first guide slot 4301 and the second guide slot 4302 are arranged in parallel in the axial direction of the guide member 43 to respectively limit the movement of the first positioning member 41 and the second positioning member 42. The first positioning member 41 is installed on the first body 11 in a manner of passing through the first guide slot 4301, and the end of the first positioning member 41 away from the first body 11 extends outwardly in a radial direction by a predetermined length to form a first step 411, the cross-sectional inner diameter of the first step 411 is larger than the slot size of the first guide slot 4301, and the first step 411 acts on the outer wall of the first guide slot 4301. The second positioning member 42 is installed on the second body 12 in a manner of passing through the second guide slot 4302, and the end of the second positioning member 42 away from the second body 12 extends outward in a radial direction by a predetermined length to form a second step 421, the cross-sectional inner diameter of the second step 421 is larger than the slot size of the second guide slot 4302, and the second step 421 acts on the outer wall of the second guide slot 4302.
