[0047] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present invention and are not limited to the scope of the present invention. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the unspecified implementation conditions are usually the conditions in routine experiments.

[0048] See also Figure 2 and Figure 3 , is a structural schematic diagram of the present invention, which provides a connecting part and a spraying mechanism for being installed on a mold with a horizontal opening direction of the mold. The mold includes a base 1, a fixed mold 2 fixed on the base 1, a movable mold 3 arranged opposite to the fixed mold 2, and a driving component 4 that drives the movable mold 3 to move horizontally relative to the fixed mold 2. After the mold is opened, the workpiece 12 located in the fixed mold 2 is ejected and falls from the mold. It is impossible to remove the workpiece by mechanical equipment, and there are safety risks in manual removal.

[0049] The above-mentioned connecting parts and spraying mechanism include a base 5 fixed on the base 1, a connecting rod 6 rotatably arranged on the base 5, a supporting component 7 rotatably arranged on the connecting rod 6 close to the first end of the fixed mold 2, and a linkage plate assembly transmission-connected to the driving component 4. The linkage plate assembly is slidably matched with the base 1, and the second end of the connecting rod 6 away from the fixed mold 2 is slidably matched with the linkage plate assembly. A guide groove 8-1 cooperating with the connecting rod 6 is provided on the linkage plate assembly. When the linkage plate assembly moves in a horizontal direction driven by the driving component 4, the connecting rod 6 rotates driven by the guide groove 8-1 to realize the lifting and lowering of the supporting component 7.

[0050] A hook is provided at the lower end of the support component 7 for hooking the workpiece, and a nozzle component can also be integrated at the lower end of the support component 7 for spraying and cleaning the mold.

[0051] like Figure 4As shown, the guide groove 8-1 includes a first groove segment 8-1a, a second groove segment 8-1b, a third groove segment 8-1c, a fourth groove segment 8-1d and a fifth groove segment 8-1e which are arranged in sequence from the movable mold 3 to the fixed mold 2. The first groove segment 8-1a and the fifth groove segment 8-1e extend in the horizontal direction and are located on the same horizontal plane below the hinge axis of the connecting rod and the base 5. The third groove segment 8-1c extends in the horizontal direction and is located on the same horizontal plane as the hinge axis. The second groove segment 8-1b extends obliquely upward from the first groove segment 8-1a to the third groove segment 8-1c. The fourth groove segment 8-1d extends obliquely downward from the third groove segment 8-1c to the fifth groove segment 8-1e.

[0052] When the mold is opened, the driving component 4 drives the movable mold 3 away from the fixed mold 2, and the linkage plate assembly moves in the horizontal direction away from the fixed mold 2. The connecting rod 6 passes through the first slot section 8-1a, the second slot section 8-1b, the third slot section 8-1c, the fourth slot section 8-1d and the fifth slot section 8-1e in sequence, driving the supporting component 7 to first descend and then ascend to complete the removal of the workpiece 12. When the mold is closed, the connecting rod 6 passes through the fifth slot section 8-1e, the fourth slot section 8-1d, the third slot section 8-1c, the second slot section 8-1b, and the first slot section 8-1a in sequence, completing the action of first descending and then ascending. After the supporting component 7 descends to between the fixed mold 2 and the movable mold 3, the mold can be sprayed and cleaned.

[0053] In order to improve the stability of the structure, Figure 5 As shown, the linkage plate assembly includes two linkage plates 8 arranged at both ends of the base 5 and arranged in the vertical direction, and the above-mentioned guide groove 8-1 is respectively provided on each linkage plate 8.

[0054] In order to facilitate the sliding cooperation between the connecting rod 6 and the linkage plate assembly, a sliding pin 6 - 1 is fixed to the second end of the connecting rod 6 , and the two ends of the sliding pin 6 - 1 are respectively slidably arranged in the two guide grooves 8 - 1 of the two linkage plates 8 .

[0055] In order to improve the continuity of the lifting and lowering action of the connecting rod 6 and reduce the wear between the connecting rod and the linkage plate 8 during the sliding process, the second groove segment 8-1b and the first groove segment 8-1a and the third groove segment 8-1c are chamfered, and the fourth groove segment 8-1d and the third groove segment 8-1c and the fifth groove segment 8-1e are chamfered.

[0056] The linkage plate assembly is fixedly connected to the power output end of the driving component 4 via the connecting plate 9. Preferably, the driving component 4 can adopt an oil cylinder or a pneumatic cylinder. A transition plate 10 is provided at the power output end of the driving component 4. The connecting plate 9 is fixedly connected to the upper end of the transition plate 10 via screws or locating pins. The side of the transition plate 19 is fixedly connected to the movable mold 3 via the guide rod assembly 11.

[0057] The working principle of the present invention is:

[0058] like Figure 6(a) to Figure 6(e) As shown, when the mold is opened, the driving component 4 drives the movable mold 3 away from the fixed mold 2, and the linkage plate assembly moves in the horizontal direction away from the fixed mold 2. When the connecting rod 6 is located in the first groove section 8-1a, the angle between the connecting rod 6 and the horizontal plane remains unchanged, that is, the height of the supporting component 7 remains unchanged. When the connecting rod 6 is located in the second groove section 8-1b, the connecting rod 6 rotates, and the supporting component 7 gradually descends. When the connecting rod 7 is located in the third groove section 8-1c, under the joint action of the second end of the connecting rod 6 and the base 5, the connecting rod 6 is in a horizontal position. At this time, the supporting component 7 descends to the gap between the fixed mold 2 and the movable mold 3 to hook the workpiece 12. When the connecting rod 6 is located in the fourth groove section 8-1d, the connecting rod 6 is gradually lifted to drive the supporting component 7 to rise and take out the workpiece 12. When the connecting rod 6 is located in the fifth groove section 8-1e, the supporting component 7 is stably located above the fixed mold 2.

[0059] like Figure 7(a) to Figure 7(e) As shown, when the mold is closed, when the connecting rod 6 passes through the fifth groove section 8-1e, the angle between the connecting rod 6 and the horizontal plane remains unchanged. At this time, the supporting component 7 is located above the fixed mold 2 and the movable mold 3. When the connecting rod 6 passes through the fourth groove section 8-1d, the connecting rod 6 drives the supporting component 7 to gradually descend. When the connecting rod 6 passes through the third groove section 8-1c, it is in a horizontal position. The supporting component 7 descends to the gap between the fixed mold 2 and the movable mold 3, and the mold can be sprayed and blown clean. When the connecting rod 6 passes through the second groove section 8-1b, the connecting rod 6 drives the supporting component 7 to gradually rise. When the connecting rod 6 is located at the starting end of the first groove section 8-1a, it returns to the initial position.

[0060] In summary, the connector and spraying mechanism can complete the removal of workpieces and the spraying and cleaning of the mold during the mold opening and closing processes, thereby improving production efficiency and reducing labor intensity.
