Description

Technical Field

[0001] The utility model relates to a hollow deep-cavity storage basket mould with a built-in core-pulling mechanism, and belongs to the field of injection moulds. Background Art

[0002] The deep cavity plastic storage basket is processed and formed by injection molding. The processing mold generally includes a cavity frame with a deep cavity and a core insert corresponding to the deep cavity. The core insert is inserted into the deep cavity of the cavity frame and forms a storage basket mold cavity with it. According to the product appearance and structural analysis, a handle hole is also provided on the mouth of the storage basket. Therefore, a corresponding handle hole core pulling mechanism is also provided on the processing mold, and the handle hole core pulling mechanism usually adopts an outer sliding core pulling structure. However, in actual production, the applicant has designed a deep cavity storage basket with a hollowed-out wall of the basket body. During processing, as the product structure changes, the hollowing on the wall of the basket body requires a molding and demoulding structure. At the same time, the hollow demoulding structure interferes with the handle hole core pulling mechanism, and the handle hole core pulling mechanism needs to be separately involved. Therefore, the corresponding molding and demoulding structure needs to be reflected on the processing mold. Therefore, the applicant has designed a hollow deep cavity storage basket mold with a built-in core pulling mechanism. Summary of the invention

[0003] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a hollow deep cavity storage basket mold with a built-in core pulling mechanism that adopts a multi-slide linkage four-open demoulding and a built-in oil cylinder core pulling structure to achieve hollow demoulding and handle hole core pulling.

[0004] The technical scheme of the hollow deep cavity storage basket mold with a built-in core pulling mechanism of the utility model is as follows: it comprises a cavity plate and a core plate, a cavity frame is arranged under the cavity plate, a core block is arranged on the core plate, the core block extends into the cavity frame, a hollow forming insert is arranged in each of the four inner walls of the cavity frame, and each hollow forming insert is connected to the cavity frame by an inclined sliding mechanism, and at the same time, a mold cavity with a hollow deep cavity storage basket is formed between each hollow forming insert and the core block, a hollow deep cavity storage basket with a handle is injection molded in the mold cavity, each hollow forming insert is driven to slide by a linkage driving mechanism through an inclined sliding mechanism, the hollow deep cavity storage basket is demolded, an inner pulling mechanism is arranged in the core plate and the core block, and the inner pulling mechanism pulls the core of the handle hole of the hollow deep cavity storage basket.

[0005] The utility model discloses a hollow deep cavity storage basket mold with a built-in core pulling mechanism, wherein the mold cavity is composed of four hollow molding inserts and a core block, and a hollow deep cavity storage basket with a handle is injection molded in the mold cavity, that is, a hollow is formed on the peripheral wall of the storage basket, and a handle hole is formed on the mouth of the storage basket. When the product is demolded, the hollow and the handle hole need to be demolded first before being taken out from the core block. Therefore, after the product is injection molded, the power of the injection molding machine first drives the mold cavity plate to separate from the mold cavity frame, so that the bottom of the storage basket is ejected (the storage basket is inverted on the core block during molding), and then the linkage drive mechanism drives the hollow molding insert to slide outward and downward (four openings) through the inclined sliding mechanism, so that the hollow molding insert is demolded from the hollow on the peripheral wall of the storage basket. At the same time, the internal pulling mechanism core pulls the handle hole of the storage basket to demold the handle hole. Finally, the storage basket is taken out from the core block by a robot, and the injection molding and demolding of the product are completed. This solution uses multiple sliders (hollow molding inserts) to form a mold cavity, and then links the four-opening outer sliding demoulding. At the same time, a core pulling mechanism is built in, which has a very beneficial and positive effect on the smooth molding and demoulding of the hollow deep cavity storage basket with handles.

[0006] The utility model discloses a hollow deep cavity storage basket mold with a built-in core pulling mechanism, wherein the oblique sliding mechanism includes oblique I-shaped guide grooves provided on the four inner walls of the cavity frame, and corresponding oblique I-shaped guide bars provided on the outer walls of each hollow molding insert, and the oblique I-shaped guide bars cooperate with the oblique I-shaped guide grooves. When demolding, the hollow molding insert is driven by the linkage driving mechanism, and slides outward and downward (four openings) under the cooperation of the oblique I-shaped guide bars and the oblique I-shaped guide grooves, so that the hollow molding insert is demolded from the hollow on the peripheral wall of the deep cavity storage basket, and the demolding is smooth. The linkage driving mechanism includes a linkage limiting plate provided between the adjacent outer walls of each hollow molding insert, a demolding frame is sleeved on the linkage limiting plate, and a driving oil cylinder is provided on the outer walls on both sides of the cavity frame, and the cylinder rod of the driving oil cylinder is connected to the demolding frame. When demolding, the driving oil cylinder pushes the demolding frame downward, and the demolding frame drives each hollow molding insert to slide through the linkage limiting plate, and the action is stable and reliable. The inner pulling mechanism includes a horizontal handle hole core pulling block and a vertical core pulling slider arranged in the core block corresponding to the handle hole. The handle hole core pulling block and the core pulling slider are connected by an inclined groove. The core pulling slider is connected to a core pulling rod, and the core pulling rod is connected to a core pulling cylinder. The core pulling cylinder is fixed to the bottom of the core plate. When pulling the core, the core pulling cylinder drives the vertical core pulling slider to move downward, and then drives the handle hole core pulling block to pull the core horizontally through the inclined groove, so that the handle hole is demoulded with smooth movement.
