Description

Technical Field

[0001] The utility model relates to the field of centering adjustment devices, in particular to a centering adjustment device for an injection platform of an injection molding machine. Background Art

[0002] The injection molding machine mainly melts the plastic raw material into liquid, then sprays it into the mold through an injection nozzle, and uses the mold to cool and shape to obtain the desired product appearance. The injection molding machine is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. The mold is generally placed on an injection table, and the injection hole on the mold needs to be centered and adjusted so that it is aligned with the injection nozzle.

[0003] For example, an injection molding machine injection table centering adjustment device disclosed in the authorization announcement number CN219381368U can control the left and right groups of first centering components to move synchronously and approach each other by controlling the rotation of the threaded rod with reverse threaded structure at the left and right ends, thereby ensuring that the displacement of the two groups of first centering components is equal, and accurate centering of the mold can be achieved; by rotating the adjustment rod, the extrusion plate threadedly connected to it is controlled to move downward, and the extrusion plate with an inclined guide groove inside can move downward to squeeze the fixed column, so that the two fixed columns respectively drive the two clamps to move toward the mold direction, and the displacement of the two clamps is equal, so the front and rear centering of the mold can be achieved.

[0004] During the above-mentioned centering adjustment, the mold is centered by rotating the threaded rod. The adjustment requires continuous twisting of the threaded rod to move the mold. The mold cannot move quickly and the overall adjustment is slow. At the same time, for some molds such as the injection hole that is not in the middle of the mold but is on the left or right side of the mold, it is difficult to achieve centering adjustment. For this reason, we propose a centering adjustment device for the injection table of an injection molding machine. Utility Model Content

[0005] The utility model aims to provide a centering adjustment device for an injection molding machine injection table. By setting a centering adjustment component, it is convenient to use a sliding component to move along a fixed track, so as to change the position of the centering component, thereby realizing rapid centering adjustment of the mold, and then using an extrusion component to extrude the positioning component so that the positioning component contacts the fixed track, thereby realizing the fixation of the centering component and its mold.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an injection molding machine injection table centering adjustment device, comprising an injection table body, a bottom plate located on the injection table body, a slide groove provided on the outer surface of the bottom plate, and a centering component located on the top of the bottom plate, wherein the bottom plate is provided with a centering adjustment component, and the centering adjustment component comprises:

[0009] An extrusion assembly, wherein the extrusion assembly is threadedly connected to the top end of the sliding assembly;

[0010] The positioning component is arranged in the middle of the sliding component, and the positioning component can move horizontally. After the extrusion component moves downward, it will squeeze the positioning component, and the positioning component can lock the position of the sliding component.

[0011] Preferably, both ends of the fixed track are configured in a U-shape, and the middle portion of the fixed track is configured in a U-shape.

[0012] Preferably, the sliding assembly includes an upper slide fixedly connected to one side of the centering assembly, two connecting plates fixedly connected to the bottom end of the upper slide, and a lower slide fixedly connected to the bottom ends of the two connecting plates.

[0013] Preferably, the extrusion assembly includes a lifting threaded rod threadedly connected to the middle part of the upper slide plate, a conical block fixedly connected to the bottom end of the lifting threaded rod, and a rotating round block fixedly connected to the top end of the lifting threaded rod.

Extrusion positioning component 8, the positioning component 8 can lock the position of the sliding component 6; when the injection hole of the mold is located on the left or right side of the mold, and then the centering adjustment is performed, the mold is placed on the bottom plate 2, and the two sliding components 6 are close to the mold, and then the centering component 4 of the prior art is used for preliminary rapid centering, and then a sliding component 6 is pushed, so that the sliding component 6 drives the mold and its other sliding component 6 to move. After the adjustment is completed, the extrusion component 7 is rotated to move the extrusion component 7 downward, so that the extrusion component 7 pushes the positioning component 8, so that the positioning component 8 fixes the position of the sliding component 6 and its mold. This design facilitates the rapid adjustment and positioning of the mold with the injection hole biased to the left or right, thereby improving the adjustment efficiency.

[0026] Even when adjusting the mold whose injection hole is located in the middle of the mold, in addition to visually aligning the injection nozzle with the injection hole, a vertically placed column can be inserted into the injection hole, the mold is placed on the bottom plate 2, and the two sliding components 6 are close to the mold, and then the centering component 4 of the prior art is used for preliminary rapid centering, and then the sliding component 6 is used to drive the mold to move until the column is aligned with the injection nozzle, and then the extrusion component 7 and the positioning component 8 are used to fix the mold, and the overall adjustment speed is also fast.
