Sliding block resetting mechanism

Abstract

The utility model relates to the technical field of injection molds, and particularly discloses a sliding block resetting mechanism which comprises a mold and a mold frame used for installing the mold, a jacking mechanism is arranged between the mold frame and the mold, an insert is installed on the mold, and a connecting assembly is arranged between the mold and a workpiece. The connecting assembly comprises a sliding block connected to the mold in a sliding mode, and the insert is installed on the sliding block through an installation unit. The sliding block drives the insert to slide in the mold through the mounting unit in the sliding stroke, so that the insert is far away from the station where the insert is located, and at the moment, when the outside touches a power switch of the jacking mechanism by mistake to enable the jacking mechanism to slide upwards, the jacking mechanism cannot abut against the insert, so that the insert cannot be damaged, and the service life of the insert is prolonged. The influence on the use of the whole injection mold caused by damage of the insert is avoided, so that the practicability of the whole injection mold can be improved, and the use effect is better.

Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to a slider resetting mechanism. Background Art

[0002] Connectors are generally used to connect wiring harnesses and wiring harnesses, and wiring harnesses and electrical components. Automobile wiring harness connectors are important components that connect various electrical and electronic equipment in the car. In order to prevent the connectors from being disengaged while the car is driving, all connectors are equipped with locking devices.

[0003] As is known, wiring harness terminals are typically produced using injection molding, a process used in the mass production of complex-shaped components. Specifically, a heated, molten material is injected into a mold cavity under high pressure, and then cooled and solidified to produce a molded product.

[0004] During operation, an injection mold consists of two parts: a movable mold and a fixed mold. The movable mold is mounted on the movable platen of the injection molding machine, while the fixed mold is mounted on the fixed platen of the injection molding machine. During injection molding, the movable and fixed molds are closed to form the gating system and the mold cavity. When the mold is opened, the movable and fixed molds separate to facilitate the removal of the plastic product.

[0005] It is well known that after injection molding is completed, an ejector mechanism is typically used to eject the workpiece from the molding cavity. However, in the prior art, this ejector mechanism is typically operated by a separate drive source and is used to unload the workpiece after the movable and fixed molds are separated. During this process, when the movable and fixed molds are separated, linkage components such as inclined guide posts are used to drive the sliders outward to avoid interfering with the workpiece unloading. After unloading the workpiece, if the ejector mechanism is used again to lift the workpiece, it can damage the inserts inside the mold, resulting in certain drawbacks. Utility Model Content

[0006] The purpose of the present invention is to provide a slider resetting mechanism to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a slider resetting mechanism, comprising a mold and a mold frame for installing the mold, a lifting mechanism is arranged between the mold frame and the mold, an insert is installed on the mold, and a connecting assembly is arranged between the mold and the workpiece, the connecting assembly comprises a slider slidably connected to the mold, and the insert is installed on the slider through an installation unit.

[0008] Furthermore, a limit member is provided between the slider and the mold to improve the stability of the slider when sliding on the mold.

[0009] Furthermore, the limiting component includes a limiting block installed on the mold, an extension bar is fixedly connected to the sliding block, a limiting groove is provided on the limiting block, and the extension bar is slidably connected in the limiting groove.

[0010] Furthermore, the slider is provided with a power groove and also includes an inclined guide column adapted to the power groove. During the mold opening stroke, the inclined guide column slides in the power groove and drives the slider to slide through the power groove.

[0011] Furthermore, the sliding block is fixedly connected to the inner side of the power slot, and the inclined guide column is provided with an inclined slot, and the protrusion is slidably connected in the inclined slot.

[0012] Furthermore, the lifting mechanism includes an ejector plate slidably connected to the mold frame, and multiple groups of ejector workpieces are fixedly connected to the ejector plate.

[0013] Furthermore, a power unit is provided between the mold frame and the ejector plate.

[0014] Furthermore, the installation unit includes a connecting block clamped on the slider, and the insert is installed on the connecting block.

[0015] Furthermore, a fastening plate is fixedly connected to the mold, and a through slot is provided on the fastening plate, and the connecting block slides on the fastening plate through the through slot.

[0016] Furthermore, a support member is provided on the bottom of the mold frame.

[0017] Compared with the prior art, the beneficial effect of the present invention is that the slider reset mechanism cooperates with the mold, the lifting structure, the insert, the connecting component and the slider, so during use, when the mold is opened, the slider is driven to slide outward, and the slider drives the insert to slide inside the mold through the installation unit during the sliding stroke, so that the insert is away from its work station. At this moment, when the power switch of the lifting mechanism is accidentally touched by the outside world to make the lifting mechanism slide upward, the lifting mechanism will not abut against the insert, so it will not cause damage to the insert, thereby avoiding damage to the insert affecting the use of the entire injection mold, thereby improving the practicality of the entire injection mold and achieving better use effect.
