Detailed Description
The advantages of the invention are further illustrated in the following description of specific embodiments in conjunction with the accompanying drawings.
Referring to fig. 1 and 2, schematic structural diagrams of an injection molding system according to a preferred embodiment of the present invention in different states are shown. The mold injection system is used for injection molding of a mold to be injected, the mold to be injected is provided with a thinner side wall part, the part is supported by a support assembly, specifically, the mold to be injected is fixed on the support assembly, the position of the support assembly can be changed, and the mold to be injected moves synchronously along with the movement of the support assembly.
In this embodiment, the support assembly includes:
supporting the slide 1
The support is provided with a supporting slide block 1 outside the injection mold, the supporting slide block supports the injection mold from bottom to top, and when the injection mold is used for injection molding, the position of the injection mold is limited by the supporting slide block 1 and is stable. And the supporting slider 1 provides supporting force for supporting the to-be-injected mold, and the influence on the surface shape of the to-be-injected mold is avoided. Furthermore, for the injection molding part with thin wall shape, each part is stressed in the stable injection molding process to avoid the generation of welding line.
It will be understood that the support slider 1 can be fixed to the injection mold after sliding in a limited position. For example, one side of the supporting slider 1 is connected to the mold to be injection molded and can be unfolded or folded in a hinge-like manner, and when the supporting slider is in the unfolded position, the supporting slider is not injection molded, and when the supporting slider is in the folded position, the supporting slider is attached to the mold to be injection molded.
-a cylinder 2
An oil cylinder 2 is arranged below the supporting slide block 1 or at the movable stroke position of the supporting slide block 1, the oil cylinder 2 is fixed on a working plane, the position of the oil cylinder is not movable, the oil cylinder is connected with the supporting slide block 1, and the supporting slide block 1 is supported and simultaneously provides movable driving force for the supporting slide block 1. For example, the oil cylinder 2 can drive the supporting slide block 1 to move up and down, left and right, or in any direction. The movable position of the support slide 1 is determined by the cylinder 2, i.e. the cylinder 2 will define the position of the mold to be injected by the support slide 1.
Signal triggering lever 4
The signal trigger rod 4 is fixed on the supporting slide block 1, and when the oil cylinder 2 drives the supporting slide block 1 to move, the signal trigger rod 4 moves synchronously. Therefore, the movement process of the mold to be injected can be converted into the movement of the signal trigger rod 4 through the supporting slide block 1. The signal trigger lever 4 may be formed in a long lever shape, a short lever shape, or a switch shape, and may have various shapes for contacting with an external switch to trigger the switch operation.
-travel switch assembly
The travel switch assembly is a component which is matched with the signal trigger rod 4 and sends out different switch signals. The automatic control device specifically comprises a first travel switch 5-1 and a second travel switch 5-2 which are respectively positioned on the travel of a signal trigger rod 4 and are in contact with the signal trigger rod 4 to generate signals.
The signal trigger rod 4 moves along with the support slide block 1 to be located at two positions, in the first position, the signal trigger rod 4 is in contact with the first travel switch 5-1, when the signal trigger rod 4 is in contact with the first travel switch 5-1, the signal trigger rod 4 is in electrical contact with the first travel switch 5-1, so that a first mold closing signal is generated and transmitted to a mold injection system, and the injection system receives the signal and starts first injection molding; similarly, when the signal trigger rod 4 moves to a second position along with the support slide block 1 and contacts with the second travel switch 5-2, a second mold closing signal is generated, so that the injection molding system is triggered to start second injection molding.
It will be appreciated that when the signal trigger lever 4 is moved again after being triggered by the first and second travel switches 5-1 and 5-2, respectively, the trigger is released and the first and second injection shots are stopped.
And because the injection molding process is carried out for many times, the supporting slide block 1 is driven by the oil cylinder 2 to carry out reciprocating motion and can move between the first travel switch 5-1 and the second travel switch 5-2 in a reciprocating way. Therefore, according to the characteristics, the supporting slide block 1 can be folded to the position of the mold to be injection molded when the signal trigger rod 4 is located at the first position and the second position, and can be unfolded to the outside of the mold to be injection molded when the signal trigger rod 4 is located between the first position and the second position.
The supporting slide block 1 is provided with a side wall supporting slide block aiming at the side wall of the injection mold to be injected, and when the injection mold is injected, the side wall of the injection mold is clamped and coated so as to stabilize the injection position. For example, the sidewall support slider is similar to a two-clip type, and clamps the sidewall portion to be injection-molded in the middle, so as to uniformly distribute the clamping force and reduce the concentrated force on the sidewall at a certain point.
And hydro-cylinder 2 is including actuating lever 8 and connecting block 3, and actuating lever 8 stretches out in the hydro-cylinder 2 to can vertically reciprocate, and connecting block 3 is connected with lateral wall support slider, as the switching medium, and is connected with actuating lever 8, and when 8 above-mentioned movements of actuating lever are pushed to hydro-cylinder 2, actuating lever 8 and then propelling movement connecting block 3, and connecting block 3 finally conducts the propelling movement to lateral wall support slider department, thereby accomplishes the reciprocating motion that supports slider 1.
The bottom of the oil cylinder 2 is provided with a fixing part 6 for fixing the oil cylinder 2 on a working plane. For example, the fixing portion 6 is provided with a fixing component, which completely adheres to the working plane and is fixedly connected, and when the driving rod 8 moves, the fixing portion 6 is fixed at the installation position.
With continued reference to fig. 1 and 2, the signal triggering rod 4 extends perpendicularly to the supporting slider 1, and the travel switch assembly is disposed parallel to the supporting slider 1 and the oil cylinder 2. For example, the driving rod 8 in the oil cylinder 2 moves along the vertical direction, the signal trigger rod 4 also moves along the vertical direction, but the extending direction of the signal trigger rod is positioned at the horizontal position, so that the travel switch assembly can be arranged not to be too close to the supporting slide block 1, and the false triggering is prevented. Under the configuration, the first travel switch 5-1 and the second travel switch 5-2 are arranged along the vertical direction, the first travel switch 5-1 is arranged at the upper part, the second travel switch 5-2 is arranged at the lower part, and when the signal trigger rod 4 is positioned at the highest position, the signal trigger rod is contacted with the first travel switch 5-1, and vice versa. Through the arrangement, the signal trigger rod 4 is in surface contact with the travel switch assembly, so that the accuracy of correct triggering is improved.
At the top of mould injection system, still be equipped with a stopper 7, it can set up directly over supporting slider 1 stroke direction, and when supporting slider 1 received the drive of actuating lever 8 drive upward movement, stopper 7 will support supporting slider 1, and its further motion is restricted, realizes anticollision function.
