After mold clamping and feeding and plasticizing, the molten plastic is injected into the cavity and cooled to form by the cooling system. Therefore, the wedge block 13 must be provided so that the core 11 does not produce displacement, thereby ensuring the accuracy of the plastic parts and the service life of the inclined guide column. At the same time, the side core slider 14 is driven by the inclined guide post 12 to gradually pull out the core 11 to both sides. The inclined guide column is made of 45 steel, heat treatment requires hardness ≥55HRC, surface roughness R0. The structure of the slider is integrated with the side core, or it can be made into a combined slider. When the mold is closed, the ejection mechanism first returns to the position before ejection under the action of the reset lever 5 and the return spring 3 (reset of the ejection mechanism), and the side core slide 14 is driven by the inclined guide post 12 to gradually return the core 11 To the position at the time of molding (reset of the side core), at this point, one molding cycle is completed and the next injection can be prepared.The connection between the side core and the slider is shown in Figure 5. In the injection molding process of plastic parts, the side core is subjected to a large thrust of the plastic melt in the direction of core pulling. In addition to the position of the oblique guide column hole on the parting surface of the slider, the projection of the oblique guide column hole should be perpendicular to the axis of the slider core pulling direction.8μm, and the inclined guide column and the fixed plate adopt a transition fit of H7/k6. In order to ensure that the side core is pulled out and reset reliably, and to ensure that the slider is stable during the movement, there is no up-and-down movement and jamming, the slider and the chute must cooperate well and guide the slide, and the slider and the chute generally cooperate It is . Injection mould The slider is an important part in the core-pulling mechanism of the inclined guide column. When the mold is opened, the moving part of the mold starts to move under the action of the injection molding machine, so that the mold is divided along the main parting surface.The mold is a pipe clamp injection mold using a side-pulling mechanism with inclined guide columns. This force is transmitted to the oblique guide column 12 through the slider 14, and the oblique guide column is an elongated rod, which is easily deformed by the force. The combined type can save high-quality steel. Installed in the guide chute of the mold, and processed together after the dynamic and fixed molds are closed. The integral type is mostly used in the case of small core and simple shape. The general core steel has higher requirements than the slider steel.. The plastic parts (pipe clamps) are formed by the cavity and the side core. When moved to the proper position, the ejection mechanism of the injection molding machine pushes the push plate 19, so that the push rod 18 pushes out the plastic parts left in the moving model cavity. The plastic part and the aggregate are moved together with the follower die under the action of the Z-shaped pulling rod 20
