Description

Technical Field

[0001] This utility model relates to the technical field of molds, and in particular to a mold fitting structure for an injection molding machine ejector roller. Background Technology

[0002] In injection molding, the ejection mechanism of the mold (such as ejector plates, ejector rollers, etc.) is used to demold the molded product from the mold. The ejector roller holes on the mold are designed to shorten the ejection time and reduce the injection cycle. They are usually distributed individually on injection molding machines. If the ejector roller hole specifications are inconsistent on different machines, it will be impossible to perform trial molding. Utility Model Content

[0003] In order to overcome the above-mentioned technical defects, the present invention provides a mold fitting structure for an injection molding machine ejector roller, which aims to solve at least one of the problems in the background art.

[0004] This utility model is implemented according to the following technical solution:

[0021] To better illustrate this utility model, a further detailed description of this utility model is provided below with reference to the accompanying drawings.

[0022] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims. In the description of this application, it should be understood that the terms "first," "second," "third," etc., are used only to distinguish similar objects and are not necessarily used to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0024] See Figure 1 This utility model discloses a mold fitting structure for an injection molding machine ejector roller, comprising:

[0025] Ejector plate;

[0026] The rear template 200 is located below the ejector plate. The rear template 200 has a first ejector hole group 210 that matches the position of the ejector roller of the first injection molding machine and a second ejector hole group 220 that matches the position of the ejector roller of the second injection molding machine. Both the first ejector hole group 210 and the second ejector hole group 220 are composed of multiple through holes.

[0027] KO column 300 is disposed in each of the through holes and connected to the ejector plate.

[0028] Compared with the prior art, this utility model simultaneously sets a first ejector pin hole group 210 and a second ejector pin hole group 220 on the rear template 200 to adapt to different models of injection molding machines, so that the same mold can be compatible with the ejection mechanism of multiple injection molding machines and meet the needs of early trial use. This design solves the industry pain point of multi-model adaptation through standardized hole group layout, and significantly reduces mold modification costs and equipment changeover time.

[0029] In this embodiment, when the ejector roller positions of the first injection molding machine part and the second injection molding machine part coincide, the through holes corresponding to the first ejector roller hole group 210 and the second ejector roller hole group 220 coincide, sharing a single KO pillar 300. When the ejector roller positions coincide, sharing the KO pillar 300 avoids redundant through holes and KO pillars 300, reducing redundant components and lowering the complexity of the mold structure.

[0030] In this embodiment, when the ejector roller positions of the first injection molding machine section and the second injection molding machine section intersect and overlap, the through holes corresponding to the first ejector roller hole group 210 and the through holes corresponding to the second ejector roller hole group 220 overlap but do not coincide. The KO pillar 300 at the through hole corresponding to the first ejector roller hole group 210 abuts against the KO pillar 300 at the through hole corresponding to the second ejector roller hole group. Compared to the original single KO pillar 300 occupying one through hole, to avoid interference, the diameters of the two KO pillars 300 in the two intersecting and overlapping through holes are relatively smaller. When the two KO pillars 300 abut against each other, the diameter of the two KO pillars 300 is at its maximum, maximizing the contact area between the ejector roller and the KO pillar 300 and ensuring the stability of the ejection.

[0031] In this embodiment, the first ejector pin hole group 210 is arranged in a centrally symmetrical manner. The centrally symmetrical first ejector pin hole group 210 ensures uniform distribution of ejection force, reduces the risk of deformation during product ejection, and improves molding quality.

[0032] In this embodiment, the second ejector hole group 220 is arranged in a centrally symmetrical manner. The centrally symmetrical second ejector hole group 220 ensures uniform distribution of ejection force, reduces the risk of deformation during product ejection, and improves molding quality.

[0033] In this embodiment, the bottom surface of the KO column 300 does not protrude from the bottom surface of the rear template 200. The absence of a protruding bottom surface of the KO column 300 ensures close contact between the rear template 200 and the injection molding machine fixing plate, preventing installation tilting or uneven force distribution caused by localized protrusions, and ensuring mold positioning accuracy and fixing reliability.

[0034] In this embodiment, the KO post 300 has a countersunk hole, and a screw fastener 400 passes through the countersunk hole to fix it to the ejector plate. The nut of the screw fastener 400 is set lower than the countersunk hole to hide the nut. The hidden nut design avoids interference with the movement of the ejector roller, and at the same time enhances the connection stability of the KO post 300 and prevents loosening.

[0035] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
