When the mold is opened, only the first loose core 23 can be opened firstly under the action of the positioning block 12; and then, opening the movable die 22, driving the second loose core 24 to be demoulded through a linkage structure, and ejecting the bracket from the fixed die 21 through an ejection mechanism. After the first core back 23 is opened, the elastic member 27 will force the positioning column 25 to pop out to the outside of the first core back 23, and when feeding, as shown in fig. 4, the nut 13 is first positioned on the feeding table 100 by the positioning member 101, and then the clamping member 102 is controlled by a robot to clamp the nut 13 on the feeding table 100 onto the positioning column 25, so that the nut 13 is fixed on the positioning column 25 by the elastic clamping member 26, and automatic assembly is realized.

However, the existing window glass carrier mold has the following defects: (1) The mold structure is relatively complex, and in the process of extracting the first loose core 23 during mold opening, the elastic part 27 can force the outer end of the positioning column 25 to extrude the surface of the mounting seat 11, so that scratches are easily formed on the surface of the mounting seat 11, and the appearance of a product is affected; (2) In order to avoid that normal production cannot be performed due to the failure of the elastic piece 27 and the elastic clamping piece 26, the elastic piece 27 and the elastic clamping piece 26 need to be replaced regularly, but the elastic piece 27 and the elastic clamping piece 26 are arranged inside the first loose core 23, so that the first loose core 23 needs to be detached for replacement, and the replacement is troublesome; (3) The feeding operation is required to be performed after the bracket is ejected from the fixed mold 21, and other operations cannot be performed during feeding, thereby reducing the production efficiency; (4) In the feeding process, the clamping piece 102 is operated by a manipulator to move between the fixed die 21 and the movable die 22, the nut 13 is assembled on the positioning column 25 facing the fixed die 21, and the clamping piece 102 is generally of a cylinder clamping jaw structure and is long in size, namely the traditional feeding structure is large in size along the axial direction of the nut 13; therefore, in order to obtain enough space for the robot and the clamping member 102 to perform the loading operation, the movable mold 22 needs to move a long enough distance, i.e. a longer guide post needs to be arranged to limit the sliding of the movable mold 22, thereby increasing the volume of the mold and reducing the mold opening and closing efficiency of the movable mold 22.

In addition, the contact area of the pushing block and the nut is increased through the positioning groove, and the pushing block and the nut are guaranteed to be stressed uniformly.

Compared with the prior art, the beneficial effect of this application lies in: (1) Because the position of the movable die corresponding to the nut is provided with a fixed hole, the position of the first loose core corresponding to the fixed hole is provided with an accommodating hole, and one end of the positioning column is detachably arranged in the fixed hole; therefore, when the mold is closed, the first loose core is controlled firstly to complete mold closing, and then the movable mold is controlled to complete mold closing, so that one end of the positioning column, which is far away from the movable mold, can be inserted into the accommodating hole, and interference between the positioning column and the first loose core is prevented. When the die is opened, the movable die is controlled to complete the die opening, so that the movable die is separated from the bracket, and the positioning column and the elastic clamping piece are separated from the nut on the bracket respectively; in the process that the movable die completes die opening, the movable die drives the second loose core in a linkage mode to complete die opening, so that the second loose core is separated from the bracket body; and then, controlling the first loose core to complete die opening, so that the first loose core is separated from the positioning block, and ejecting the bracket through the ejector rod. Compared with the traditional mold structure, the vehicle window glass bracket mold does not need to be provided with an elastic piece, a boss and a corresponding matched structure, so that the mold structure is simpler, and the processing difficulty of the positioning column is reduced; in the die opening process, the outer end of the positioning column cannot contact the plastic part on the bracket, so that the product cannot be scratched.

(2) One end of the positioning column is detachably arranged in the fixing hole, namely the positioning column is detachably arranged on the movable die; therefore, when the elastic clamping piece needs to be replaced, the elastic clamping piece can be replaced only by disassembling the positioning column under the condition that the movable die is opened, and the replacement is more convenient.

Referring to fig. 5 to 9, an embodiment of the present application provides a vehicle window glass bracket mold including a fixed mold 21, a movable mold 22, a first core back 23, a second core back 24, a positioning column 25, and an elastic clamping member 26; a fixed hole 221 is formed in the movable die 22 at a position corresponding to the nut 13, an accommodating hole 231 is formed in the first loose core 23 at a position corresponding to the fixed hole 221, the inner diameter of the accommodating hole 231 is equal to or larger than the inner diameter of the nut 13, and the outer diameter of the accommodating hole 231 is smaller than the outer diameter of the nut 13 (the outer diameter of the nut 13 refers to the inner diameter of an inscribed circle of a regular polygon on the outer side of the nut 13, taking the nut 13 of a regular hexagon as an example, the outer diameter refers to the inner diameter of an inscribed circle of a regular hexagon, the same applies below); one end of the positioning column 25 is detachably disposed in the fixing hole 221, and the other end of the positioning column 25 is inserted into the accommodating hole 231; the outer diameter of the positioning column 25 is matched with the inner diameter of the nut 13, and the outer wall of the positioning column 25 is provided with a mounting groove 251; a spring clamp 26 is provided in the mounting groove 251, the spring clamp 26 being used to clamp the nut 13 to the locating post 25. The fixed die 21, the movable die 22, the first loose core 23, the second loose core 24 and the elastic clamping member 26, and the installation modes between the fixed die and the movable die are all the prior art, and are not described in detail herein.

As shown in fig. 10 and 11, when the mold is closed, the first core back 23 is controlled to complete the mold closing, and then the movable mold 22 is controlled to complete the mold closing, so that one end of the positioning post 25 away from the movable mold 22 can be inserted into the accommodating hole 231, and interference between the positioning post 25 and the first core back 23 is prevented. When the mold is opened, as shown in fig. 12 and 13, the movable mold 22 is controlled to complete the mold opening, so that the movable mold 22 is separated from the bracket, and the positioning column 25 and the elastic clamping piece 26 are separated from the nut 13 on the bracket respectively; in the process that the movable die 22 completes die opening, the movable die 22 drives the second loose core 24 to complete die opening through the existing linkage mode, so that the second loose core 24 is separated from the bracket body 10; next, as shown in fig. 14 and 15, the first loose core 23 is controlled to complete mold opening, so that the first loose core 23 is separated from the positioning block 12, and then the carrier can be ejected by the ejector rod. Compared with the traditional mold structure, the vehicle window glass bracket mold does not need to be provided with the elastic piece 27, the boss 28 and a corresponding matched structure, so that the mold structure is simpler, and the processing difficulty of the positioning column 25 is reduced; in the mold opening process, the outer end of the positioning column 25 cannot contact the plastic part on the bracket, so that the product cannot be scratched.

In addition, one end of the positioning column 25 is detachably arranged on the fixing hole 221, that is, the positioning column 25 is detachably arranged on the movable mold 22; therefore, when the elastic clamping member 26 needs to be replaced, the elastic clamping member 26 can be replaced only by detaching the positioning column 25 under the condition that the movable die 22 is opened, and the replacement is more convenient.

In addition, since one end of the positioning column 25 is detachably disposed in the fixing hole 221 (i.e., the movable mold 22), the outer diameter of the positioning column 25 is adapted to the inner diameter of the nut 13, and the outer wall of the positioning column 25 is provided with a mounting groove 251; since the elastic clamping piece 26 is arranged in the mounting groove 251, the elastic clamping piece 26 is used for clamping the nut 13 on the positioning column 25; therefore, after the movable die 22 completes die opening and before the bracket is ejected, the nut 13 is automatically assembled on the positioning column 25 through the feeding device, the positioning column 25 limits the nut 13 to generate radial displacement, and the elastic clamping piece 26 limits the nut 13 to generate axial displacement, so that the nut 13 is locked on the positioning column 25 (namely on the movable die 22), and after the bracket is ejected completely, the first core pulling 23 and the movable die 22 (the second core pulling 24) can be controlled to be matched, so that the time for waiting for feeding is saved, and the production efficiency is further improved. It should be noted that, the opening and closing stroke of the first loose core 23 is smaller than the opening and closing stroke of the movable die 22, so that even when the first loose core 23 and the movable die 22 start to be closed simultaneously, the first loose core 23 can be ensured to be closed first; when the movable die 22 is clamped, the second loose core 24 is reversely acted on by the existing linkage mode, so that the second loose core 24 and the movable die 22 are clamped simultaneously. The manner of ejecting the tray is not limited, and the tray may be ejected by an ejector (as shown in fig. 15), or may be removed by another conventional structure. In addition, the automatic feeding of nut 13 both can adopt current material loading structure, also can adopt the automatic feeding device that this application newly provided, but the latter is less at the whole size of nut 13 axis direction to can realize automatic feeding under the condition of littleer operating space, not only be favorable to reducing the whole volume of mould, can avoid again that material loading operation and other operations (such as the operation of ejecting bracket) produce the interference between, thereby guarantee the normal operation of mould.

Referring to fig. 9, 11, 13 and 15, in this embodiment, an open slot 232 is formed in the first loose core 23 at a position corresponding to the end of the mounting seat 11, and an abdicating slot 222 is formed in the movable die 22 at a position corresponding to the open slot 232; the mold further comprises a forming block 29 for forming the end portion of the mounting seat 11, one end of the forming block 29 is fixed to the open groove 232, and the other end of the forming block 29 is inserted into the avoiding groove 222. When the movable die 22 is opened, the second loose core 24 is still inside the bracket body 10, that is, the second loose core 24 can urge the bracket body 10 and the movable die 22, so that the bracket body 10 cannot move along with the movable die 22; meanwhile, the first loose core 23 is pressed on the positioning block 12, so that the positioning block 12 is prevented from being separated from the fixed die 21, namely, the part between the bracket body 10 and the mounting seat 11 is prevented from moving along with the movable die 22; meanwhile, the forming block 29 is pressed on the end of the mounting seat 11 (i.e. the end of the mounting seat 11 far away from the bracket body 10), so as to ensure that the end of the mounting seat 11 does not move along with the movable mold 22. In addition, the receding groove 222 can be matched with the forming block 29 on one hand, so that the forming block 29 and the movable die 22 are not interfered with each other, and the complete sealing performance of the forming cavity is ensured; on the other hand, the relief groove 222 is used for accommodating and mating the sealing assembly 32, thereby realizing automatic feeding of the nut 13.

Referring to fig. 7 and 21, in the present embodiment, the fixing hole 221 includes a circular hole 2211 and an internal threaded hole 2212 that are coaxially disposed; one end of the positioning column 25 close to the fixing hole 221 is coaxially provided with a cylindrical rod 252 and a threaded rod 253, the cylindrical rod 252 is slidably and rotatably arranged in the circular hole 2211, and the threaded rod 253 is in threaded connection with the internal threaded hole 2212. The threaded rod 253 is matched with the internal threaded hole 2212 through threads, so that the positioning column 25 can be detachably mounted; the sliding fit between the cylindrical rod 252 and the circular hole 2211 improves the assembly accuracy of the positioning column 25. In addition, it will be appreciated that the positions of the cylindrical rod 252 and the threaded rod 253 may be interchanged, i.e., when the cylindrical rod 252 is between the threaded rod 253 and the positioning post 25, the outer diameter of the cylindrical rod 252 (i.e., the inner diameter of the circular hole 2211) should be greater than or equal to the outer diameter of the threaded rod 253 (i.e., the inner diameter of the internally threaded hole 2212); conversely, when the threaded rod 253 is between the cylindrical rod 252 and the positioning post 25, the outer diameter of the cylindrical rod 252 (i.e., the inner diameter of the circular hole 2211) should be less than or equal to the outer diameter of the threaded rod 253 (i.e., the inner diameter of the internally threaded hole 2212). In addition, the positioning column 25 can be detachably connected to the fixing hole 221 by other detachable mounting methods, such as direct screw connection, snap connection, and the like.

Referring to fig. 21, in the present embodiment, the inner diameter of the circular hole 2211 and the inner diameter of the screw hole are both smaller than the outer diameter of the nut 13. When both the inner diameter of the circular hole 2211 and the inner diameter of the threaded hole are smaller than the outer diameter of the nut 13, the joint between the cylindrical rod 252 and the circular hole 2211 (or the joint between the threaded rod 253 and the internally threaded hole 2212) is pressed only against the nut 13 and not against the mount 11, so that no flash is formed on the mount 11.

Referring to fig. 7, in the present embodiment, a rotating portion 254 is disposed at an end of the positioning pillar 25 away from the fixing hole 221. The rotating part 254 is convenient for rotating the positioning column 25, so that the threaded rod 253 is connected with and detached from the internal threaded hole 2212.

Referring to fig. 16 to 19, the present application further provides an automatic feeding device, which includes a robot, a feeding rail 31, a sealing assembly 32, a pushing assembly 33, and a stopping assembly 34; the rear end of the feeding rail 31 is arranged on the manipulator, one side of the feeding rail 31 is of an open structure, the distance between the open structure and the opposite side of the feeding rail 31 is adaptive to the thickness of the nut 13, and one side, far away from the open structure, of the front end of the feeding rail 31 is provided with a yielding hole 311 in a penetrating mode; the sealing assembly 32 is arranged on the feeding rail 31 in a front-back sliding manner, so that the nut 13 is limited from falling off from the open structure; the pushing assembly 33 is arranged at the rear end of the feeding rail 31, and the pushing assembly 33 is used for pushing the nut 13 in the feeding rail 31 to move forwards; the stop component 34 is arranged at the front end of the feeding rail 31, and the stop component 34 is used for limiting the nut 13 in the feeding rail 31 to move forwards continuously; after the movable die 22 is opened, the manipulator is used for driving the feeding rail 31 to move forwards until the nut 13 at the front end of the feeding rail 31 is aligned with the positioning column 25 on the movable die 22, the manipulator is used for driving the feeding rail 31 to move towards the direction of the positioning column 25 until the opening structure is contacted with the movable die 22, the corresponding nut 13 is automatically assembled on the positioning column 25, one end, far away from the movable die 22, of the positioning column 25 is inserted into the abdicating hole 311, and the sealing assembly 32 is accommodated in the abdicating groove 222; the positioning posts 25 are used to force the corresponding nuts 13 apart from the feeding rail 31 when the stop assemblies 34 are unlocked and the robot is used to drive the feeding rail 31 rearward.

The automatic feeding process of the automatic feeding device comprises the following steps: as shown in fig. 20 to 24, after the movable mold 22 is opened, the feeding rail 31 is driven by the robot to move forward, so that the nut 13 at the front end of the feeding rail 31 is aligned with the positioning post 25 on the movable mold 22; then, the feeding rail 31 is driven by the manipulator to move towards the positioning column 25, before the positioning column 25 is inserted into the corresponding nut 13, the sealing assembly 32 needs to be driven to slide backwards to the position corresponding to the abdicating groove 222, so as to open the open structure, so that the positioning column 25 can be inserted into the corresponding nut 13, and the open structure can be contacted with the movable mold 22; when the open structure is contacted with the movable mold 22, the corresponding nut 13 is automatically assembled on the positioning column 25, meanwhile, one end of the positioning column 25, which is far away from the movable mold 22, is inserted into the abdicating hole 311, so that interference between the positioning column 25 and the feeding rail 31 is prevented, and the sealing assembly 32 is accommodated in the abdicating groove 222, so that interference between the sealing assembly 32 and the movable mold 22 is prevented; finally, the feeding rail 31 is driven to move backwards through the manipulator, the stopping component 34 is opened, the nut 13 sleeved on the positioning column 25 can be separated from the feeding rail 31 under the action of the positioning column 25, and the nut 13 is clamped on the positioning column 25 by the elastic clamping component 26, so that the automatic feeding of the nut 13 can be completed; after the feeding is completed, the pushing assembly 33 pushes the nuts 13 inside the feeding rail 31 to move forward by a distance of one nut 13, and the stopping assembly 34 is restarted to stop the nuts 13 inside the feeding rail 31 from moving forward continuously, and slide the sealing assembly 32 forward again to seal the open structure, so that the nuts 13 inside the feeding rail 31 are prevented from falling off from the open structure. Compared with the traditional feeding structure, the automatic feeding device has smaller size along the axial direction of the nut 13, namely, the required operation space is smaller, so that the feeding operation is realized under the condition that the movable die 22 is opened for a shorter distance, and the size of the die is reduced, and the die opening and closing efficiency of the movable die 22 is improved.

In order to improve the production efficiency, a plurality of molding cavities are generally provided in the mold, so that a plurality of carriers are injection molded at one time. It can be understood that each molding cavity needs to provide a positioning column 25 (i.e. an automatic feeding device), and in order to reduce the occupied space and cost of the manipulator, the automatic feeding devices (excluding the manipulator) associated with the molding cavities on the same side of the mold are mounted on the same manipulator through the same mounting plate 35 (as shown in fig. 16), so that the automatic feeding operation of a plurality of nuts 13 can be realized by one manipulator.

It can be understood that, in the feeding process, after the nut 13 is separated from the feeding track 31, if the abdicating groove 222 does not penetrate through the outer side surface of the movable mold 22, the feeding track 31 is driven by the manipulator to move a distance in the direction away from the movable mold 22, and then the abdicating groove 222 can be withdrawn backwards, otherwise, interference is generated between the abdicating groove 222 and the pushing plate 322 and the sliding cover 321; however, when the receding groove 222 penetrates the outer side surface of the movable mold 22 (as shown in fig. 5 and 20), the receding groove 222, the push plate 322 and the sliding cover 321 do not interfere with each other, and the loading rail 31 can be directly retracted by the robot.

Referring to fig. 17 to 19, in the embodiment, the sealing assembly 32 includes a sliding cover 321, a pushing plate 322 and a first elastic member 323, the sliding cover 321 is connected to the feeding rail 31 in a front-back sliding manner; the first elastic member 323 is disposed between the sliding cover 321 and the feeding track 31, and the first elastic member 323 is used for forcing the sliding cover 321 to slide forward; the push plate 322 is disposed at the front end of the sliding cover 321, and when the manipulator drives the feeding rail 31 to move forward, the inner sidewall of the receding groove 222 forces the sealing assembly 32 to slide backward through the push plate 322. In the process that the manipulator drives the feeding track 31 to move forward until the baffle is in contact with the inner side wall of the abdicating groove 222, the inner side wall of the abdicating groove 222 can limit the baffle (i.e. the sliding cover 321) to continue moving forward along with the feeding track 31, i.e. the sliding cover 321 slides backward relative to the feeding track 31, so that the front end of the open structure can be gradually opened (as shown in fig. 21); when the nut 13 at the front end of the feeding track 31 is aligned with the positioning column 25, the manipulator drives the feeding track 31 to move towards the direction of the positioning column 25, and at this time, the baffle plate slides along the inner side wall of the abdicating groove 222, so that the baffle plate and the sliding cover 321 are accommodated in the abdicating groove 222 (as shown in fig. 22), and the contact between the open structure and the movable mold 22 is not limited, and the nut 13 can be completely assembled in place; when the manipulator drives the feeding rail 31 to move backward, the sliding cover 321 moves forward relative to the feeding rail 31 under the elastic force of the first elastic member 323, thereby automatically sealing the open structure. As can be seen from the above, the sealing assembly 32 with this structure can stably operate without separately providing a power device for driving, and is simpler to control and lower in cost.

Referring to fig. 17 to 19, in the present embodiment, a notch 312 is formed at a side of the front end of the feeding rail 31 adjacent to the open structure; the stopping assembly 34 includes a stopping frame 341, a stopping block 342 and a second elastic member 343, the stopping frame 341 is disposed in the notch 312; the stop block 342 is slidably disposed on the stop frame 341, and the outer end of the stop block 342 is provided with a first inclined surface 3421 for fitting the outer side surface of the nut 13; the second elastic member 343 is disposed on the stopping frame 341, and the second elastic member 343 is configured to force the stopping block 342 to slide to the inside of the feeding track 31, so as to limit the forward movement of the nut 13 in the feeding track 31; when the manipulator drives the feeding rail 31 to move backward, the outer side surface of the corresponding nut 13 forces the stopper 342 to slide to the outside of the feeding rail 31 through the first inclined surface 3421, thereby separating the corresponding nut 13 from the feeding rail 31. As shown in fig. 23, when the manipulator drives the feeding rail 31 to move backward, the outer side surface of the corresponding nut 13 forces the stop block 342 to slide to the outside of the feeding rail 31 through the first inclined surface 3421, so as to release the limit effect of the stop block 342 on the nut 13, and thus the corresponding nut 13 can be normally separated from the feeding rail 31 to complete the feeding operation; after the corresponding nut 13 is separated from the stop block 342, the stop block 342 slides to the inside of the feeding rail 31 again under the action of the second elastic member 343, so as to limit the nut 13 in the feeding rail 31 from sliding out forwards. As can be seen from the above, the stop assembly 34 with this structure can stably operate without separately providing a power device for driving, and is simpler to control and lower in cost.

Referring to fig. 17 to 19, in the present embodiment, the outer end of the stopper 342 is provided with a second inclined surface 3422 for adapting to the outer side surface of the nut 13, and when the nut 13 is replenished into the charging rail 31 from the front end of the charging rail 31, the corresponding nut 13 forces the stopper 342 to slide to the outside of the charging rail 31 by the second inclined surface 3422 to fit the corresponding nut 13 into the charging rail 31. Under the action of the second inclined surface 3422, as shown in fig. 17, on one hand, the nut 13 can be supplemented to the interior of the feeding rail 31 from the front end of the feeding rail 31, that is, the nut 13 is forcibly pushed into the interior of the feeding rail 31, at this time, the outer side surface of the nut 13 is squeezed on the second inclined surface 3422, so that the stop block 342 is forced to slide to the exterior of the feeding rail 31, and the nut 13 can be supplemented to the interior of the feeding rail 31, thereby realizing the filling operation; as shown in fig. 23, on the other hand, during the feeding process, when the nuts 13 are disengaged from the feeding rail 31, the second inclined surface 3422 can separate the stop block 342 from the corresponding nut 13 earlier, and the stop block 342 can slide into the feeding rail 31 earlier under the action of the second elastic member 343, so as to prevent the other nuts 13 in the feeding rail 31 from falling off from the front end of the feeding rail 31. It is understood that, in addition to the above-mentioned filling operation by means of the second inclined surface 3422, the filling operation can also be realized by opening the sealing assembly 32 (i.e. the sliding cover 321), and the filling operation can also be realized by means of forcing the stopper 342 to slide by external force.

Referring to fig. 18, 19 and 24, in the present embodiment, the pushing assembly 33 includes a pushing block 331 and a third elastic member 332; the pushing block 331 is slidably disposed on the feeding rail 31 in a front-back direction, a positioning groove 3311 for fitting the nut 13 is disposed at a front end of the pushing block 331, and a rear end of the pushing block 331 is connected to a rear end of the feeding rail 31 through a third elastic member 332. After each feeding is finished, under the action of the third elastic member 332, the pushing block 331 pushes other nuts 13 in the feeding rail 31 to move forward by the distance of one nut 13, so that the sustainability of automatic feeding is ensured. In addition, the positioning slot 3311 can increase the contact area between the pushing block 331 and the nut 13, thereby ensuring uniform stress between the pushing block 331 and the nut 13.
