As shown in FIG. 1, the present invention discloses an injection molding production apparatus 10, comprising: an injection mechanism 20, a mold molding mechanism 30, and a material-taking robot 40.

The mold forming mechanism 30 includes a mold protection cabinet 50 and a mold assembly 60 accommodated in the mold protection cabinet 50. The mold protection cabinet 50 is used for protecting the mold assembly 60 therein, and the mold protection cabinet 50 also plays a role of isolating the mold assembly 60 with high temperature during the injection molding production process.

Specifically, as shown in fig. 2 and 3, the mold protection cabinet 50 has a sliding door 51 and a door frame 52 engaged with the sliding door 51, the sliding door 51 is provided with a locking device 100, and the door frame 52 is provided with a lock device 200 engaged with the locking device 100.

As shown in fig. 4 and 5, the lock body device 200 includes: a driving assembly 210, an intermediate link 220, and a latch hook assembly 230.

As shown in fig. 5, the driving assembly 210 includes a rotating wheel handle 211 and a rotating cam plate 212. The rotating wheel handle 211 and the rotating cam plate 212 are respectively located at two sides of the door frame 52, the rotating wheel handle 211 and the rotating cam plate 212 are connected through a transmission shaft 213, the door frame 52 is provided with a lifting guide groove 521, and the transmission shaft 213 penetrates through the lifting guide groove 521. Thus, the turning wheel handle 211 and the turning cam plate 212 can be rotated and lifted on the door frame 52 by the engagement of the transmission shaft 213 with the lifting guide groove 521.

As shown in fig. 6, the intermediate connector 220 includes a lifting rod 221 and an anti-falling stopper 222 disposed on the lifting rod 221. The lifting rod 221 is provided with a first movable pin 223, and correspondingly, the plate surface of the rotating cam plate 212 is provided with a bolt hole 214, and the first movable pin 223 is rotatably inserted into the bolt hole 214. The door frame 52 is provided with an anti-deviation limiting block 522, the anti-deviation limiting block 522 is provided with an anti-deviation limiting groove 523, and the lifting rod 221 is limited in the anti-deviation limiting groove 523. Thus, the lifting rod 221 is limited by the anti-deviation limiting block 522, and cannot move horizontally but can only do vertical lifting movement.

It should be noted that the central axis of the transmission shaft 213 is aligned with the central axis of the first movable pin 223, so that the position of the first movable pin 223 of the lift lever 221 is not changed when the turning wheel handle 211 and the turning cam plate 212 are turned.

As shown in fig. 6, the latch hook assembly 230 includes a sliding rod 231 and a latch hook body 232. Specifically, the elevating rod 221 has an elevating guide groove 224, and the sliding rod 231 is movably received in the elevating guide groove 224. Meanwhile, the sliding rod 231 is provided with a second movable pin 233, and correspondingly, the plate surface of the rotating cam plate 212 is provided with an arc-shaped guide slot 215 (as shown in fig. 5), and the second movable pin 233 is movably inserted into the arc-shaped guide slot 215.

It should be noted that the arc-shaped guide slot 215 has a locking end 2151 and an unlocking end 2152 (shown in fig. 5), the distance between the locking end 2151 and the latch hole 214 is L1, and the distance between the unlocking end 2152 and the latch hole 214 is L2, where L1< L2. When the rotating cam plate 212 rotates, the second movable pin 233 inserted into the arc-shaped guide slot 215 is moved back between the upper locking end 2151 and the lower unlocking end 2152, and the relative position between the slide bar 231 and the lift bar 221 is changed due to the difference in length between the distances L1 and L2, which will be described later.

As shown in fig. 7 and 8, the locking device 100 includes a locking stationary member 110 and a locking movable member 120. The locking fixing member 110 is fixed to a door panel of the sliding door 51, and the locking moving member 120 is elastically and movably disposed on the locking fixing member 110 by the return elastic member 130. The latch hook body 232 is provided with a latch slot 234, a slot wall of the latch slot 234 is provided with a first plane locking surface 2341 (as shown in fig. 6), the latch movable member 120 is provided with a second plane locking surface 121 matched with the first plane locking surface 2341, and the first plane locking surface 2341 is matched with the second plane locking surface 121 to realize the one-stage locking of the latch device 100 and the latch device 200, which will be explained below. In addition, the locking moving member 120 further has a locking guide surface 122, so that the locking process can be more smooth.

The operation of the locking device 100 and the lock body device 200 will be explained as follows:

before locking, the locking device 100 and the lock body device 200 are positioned as shown in fig. 3, wherein the second movable pin 233 is located at the unlocking terminal end 2152 of the arc-shaped guide slot 215.

The locking process can be divided into two stages, and the specific process is as follows:

in the primary locking, the sliding door 51 is moved toward the door frame 52, and the locking device 100 and the lock device 200 are engaged with each other. Specifically, first, the locking moving element 120 touches the locking hook body 232 and is pressed by the locking hook body 232, the elastic restoring element 130 on the locking moving element 120 is compressed, and the locking moving element 120 moves toward the locking fixing element 110 to avoid a position for the locking hook body 232. When locking hook body 232 passes over locking moveable member 120 along locking guide surface 122 on locking moveable member 120, locking device 100 is fully inserted into locking slot 234, and at this time, locking moveable member 120 is no longer pressed by locking hook body 232, and locking moveable member 120 is reset under the restoring force of the elastic reset member. At this time, the first planar locking surface 2341 on the slot wall of the locking slot 234 is clamped on the second planar locking surface 121 on the locking moving member 120, and the locking device 100 and the lock body device 200 complete the first-stage locking;

during secondary locking, an operator rotates the rotating wheel handle 211 on the door frame 52, the rotating wheel handle 211 drives the rotating cam plate 212 to rotate together, the arc-shaped guide groove 215 on the rotating cam plate 212 also rotates, at the moment, the relative position of the arc-shaped guide groove 215 and the second movable pin 233 accommodated in the arc-shaped guide groove 215 changes, the unlocking terminal 2152 starts to be far away from the second movable pin 233, and the opposite locking terminal 2151 starts to be close to the second movable pin 233; in this process, since the distance L1< L2 is that the pin hole 214 is continuously close to the second movable pin 233, and since the first movable pin 223 of the lifter 221 is inserted into the pin hole 214, the lifter 221 is continuously lifted up along the sliding rod 231 toward the latch hook body 232, and the anti-falling stopper 222 provided on the lifter 221 is also continuously close to the latch groove 234; finally, when the second movable pin 233 is located at the locking end 2151, the anti-slip stopper 222 completely closes the opening of the locking groove 234, i.e., the locking device 100 is completely wrapped in the locking groove 234, and the locking device 100 and the lock body device 200 complete the secondary locking;

correspondingly, the unlocking operation is also divided into two stages, and the specific process is as follows:

during primary unlocking, the rotating wheel handle 211 is rotated reversely, the rotating wheel handle 211 drives the rotating cam plate 212 and the arc-shaped guide slot 215 to rotate together, at the moment, the relative positions of the arc-shaped guide slot 215 and the second movable pin 233 change, the locking end point 2151 starts to be far away from the second movable pin 233, and the unlocking end point 2152 starts to be close to the second movable pin 233; in the process, due to the distance L1< L2, the pin hole 214 is continuously far away from the second movable pin 233, the lifting rod 221 is continuously slid along the sliding rod 231 in the direction far away from the locking hook body 232, the anti-falling baffle 222 arranged on the lifting rod 221 is also continuously far away from the locking groove 234, and finally, when the second movable pin 233 is at the unlocking terminal end 2152, the anti-falling baffle 222 is completely separated from the locking groove 234, the notch of the locking groove 234 is reopened, and the locking device 100 and the lock body device 200 complete the primary unlocking;

during secondary unlocking, since the first planar locking surface 2341 on the groove wall of the locking groove 234 is clamped on the second planar locking surface 121 on the locking moving member 120, the locking hook body 232 needs to be lifted for a certain distance, so that the locking device 100 can be separated from the open notch of the locking groove 234. An operator needs to lift the rotating wheel handle 211 with one hand, and the rotating wheel handle 211 drives the rotating cam plate 212 and the lifting rod 221 to lift together, and it is noted that since the rotating cam plate 212 does not rotate, the distance between the latch hole 214 and the second movable pin 233 does not change, and therefore, the lifting of the rotating cam plate 212 also drives the lifting of the latch hook assembly 230; the latch hook body 232 is also lifted for a certain distance, at this time, the first planar locking surface 2341 and the second planar locking surface 121 are no longer mutually clamped, and the operator pulls the sliding door 51 by another hand, so that the locking device 100 is separated from the latch device 200, and secondary unlocking is completed.

The design principles of the locking device 100 and the lock body device 200 are explained as follows:

referring to fig. 5, in the present embodiment, the door frame 52 is formed with a lifting guide slot 521, and the lifting guide slot 521 provides a support for locking and unlocking the locking device 100 and the lock body device 200. Specifically, in the secondary locking process, the lifting rod 221 lifts to drive the driving assembly 210 to lift together, and the lifting guide slot 521 provides a structural condition basis for lifting the driving assembly 210; during secondary unlocking, the lock body device 200 needs to be lifted for a certain distance, and the lifting guide groove 521 provides a structural condition basis for lifting the lock body device 200.

In this embodiment, the door frame 52 is provided with an anti-deviation limiting block 522, the anti-deviation limiting block 522 has an anti-deviation limiting groove 523, and the lifting rod 221 is limited in the anti-deviation limiting groove 523, so that the lifting rod 221 is not deflected by the contact of the locking device 100 during the primary locking process, and can still be kept in the vertical position.

Referring to fig. 8, in the present embodiment, the locking fixing member 110 is provided with an accommodating groove 111, the return elastic member 130 is completely accommodated in the accommodating groove 111, and the locking moving member 120 is partially accommodated in the accommodating groove 111, so that the locking moving member 120 can move up and down more firmly along the wall of the accommodating groove 111 during the primary locking process, thereby achieving avoidance.

In this embodiment, the elastic return element 130 is a spring structure, so that the elastic return element 130 can rapidly convert the compression potential energy into the elastic return force during the first-stage locking.

In this embodiment, the door panel of the sliding door 51 is provided with a sliding handle, so that the operator can operate the sliding door 51 more conveniently in the locking and unlocking processes.

In the present embodiment, the material taking robot 40 includes: a translation module 41, a lifting module 42 and a mechanical gripper 43. The translation module 41 drives the mechanical clamping jaw 43 to reciprocate along the horizontal direction, and the lifting module 42 drives the mechanical clamping jaw 43 to reciprocate along the vertical direction. The translation module 41 is a motor-screw driving structure, and the lifting module 42 is a motor-screw driving structure, so that a series of actions of taking out a product from the mold forming mechanism 22 by the mechanical clamping jaw 233 and placing the product on the transmission mechanism 30 can be realized.

In summary, the injection molding production apparatus 10 disclosed in the present invention has a locking function and requires specific unlocking operation, so as to effectively protect the mold assembly 60 in the mold protection cabinet 50 and also protect the personal safety of the operator.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
