Description

Technical Field

[0001] This utility model belongs to the field of plastic injection molding technology, specifically relating to an improved inclined ejector mechanism for injection molding of automotive plastic parts. Background Technology

[0002] In injection molding, mold design changes and mold failure repairs are unavoidable. The ejector mechanism is a high-frequency moving component in an injection mold; typically, the ejection system in a single mold operates over 500,000 times. During production, problems such as ejector jamming and poor guide sliding frequently occur. Occasionally, customers may change the product structure design, requiring reprocessing of the ejector. Whether due to production abnormalities or customer design changes, machining the ejector-related parts necessitates removing them from the mold. Traditionally, the ejector and ejector guide are connected, with the guide fixed to the lower ejector plate using screws. When the ejector or guide malfunctions or requires repair due to design changes, all mold plates and parts must be dismantled before the ejector and guide can be removed, followed by machining related to the design change. This process is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an improved mechanism for injection molding inclined ejector of automotive plastic parts, which addresses the current state of the technology. By modifying the structure of this type of inclined ejector mechanism, parts such as the inclined ejector and the inclined ejector guide slide can be quickly removed without removing the template and other components, thus achieving efficient maintenance and efficient design and processing.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an improved inclined ejector mechanism for injection molding of automotive plastic parts, including a mold core, a template, an inclined ejector, an upper ejector plate, a lower ejector plate, and a lower fixing plate. The inclined ejector is characterized by an inclined ejector guide slide installed between the inclined ejector and the upper ejector plate, the inclined ejector passing through the mold core and the template and being movably connected to the inclined ejector guide slide, a clearance groove being opened on the template, a fixing block being provided on the lower ejector plate, the inclined ejector guide slide being installed on the fixing block, and mounting grooves being opened on the upper ejector plate, the lower ejector plate, and the lower fixing plate.

[0005] In the aforementioned improved inclined ejector mechanism for injection molding of automotive plastic parts, the inclined ejector guide slide is provided with a first screw and a second screw. The inclined ejector guide slide is fixed to the fixing block by the first screw, and the fixing block is fixed to the lower ejector plate by the second screw.

[0006] In the above-mentioned improved inclined ejector mechanism for injection molding of automotive plastic parts, the mounting groove of the upper ejector plate is a first mounting groove, the mounting groove of the lower ejector plate is a second mounting groove, and the first mounting groove and the second mounting groove are interconnected.

[0007] In the above-mentioned improved mechanism for injection molding of automotive plastic parts, the mounting groove of the lower fixing plate is a third mounting groove, which is connected to the bottom of the lower ejector plate, and the width of the third mounting groove is greater than the width of the fixing block.

[0008] Compared with the prior art, the advantages of this utility model are that by innovating the structure of this type of inclined ejector mechanism, mounting slots that facilitate installation and disassembly are designed on the ejector plate and fixing block of the mold, and the inclined ejector guide slide is fixed by screws using an independent fixing block, making the inclined ejector related components more flexible in installation and disassembly. This allows the inclined ejector, inclined ejector guide slide and other parts to be quickly removed without removing the template and other components, achieving efficient maintenance, efficient design and processing, saving production and manufacturing costs, and shortening the development and manufacturing cycle. Attached Figure Description

[0009] Figure 1 This is a schematic diagram of an improved inclined ejector mechanism used in the injection molding of automotive plastic parts. Detailed Implementation

[0010] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0011] In the figure, mold core 100; template 200; angled ejector 300; upper ejector plate 400; lower ejector plate 500; lower fixing plate 600; clearance groove 700; fixing block 800; first screw 900; second screw 1000; first mounting groove 1001; second mounting groove 1002; third mounting groove 1003.

[0012] like Figure 1As shown, this improved inclined ejector mechanism for injection molding of automotive plastic parts includes a mold core 100, a mold plate 200, an inclined ejector 300, an upper ejector plate 400, a lower ejector plate 500, and a lower fixed plate 600. An inclined ejector guide slide is installed between the inclined ejector 300 and the upper ejector plate 400. The inclined ejector 300 passes through the mold core 100 and the mold plate 200 and is movably connected to the inclined ejector guide slide. A clearance groove 700 is opened on the mold plate 200, with a depth of S1, serving as the movement space for the inclined ejector guide slide to move upward. 1. The ejection stroke must be greater than the ejection stroke S to avoid interference between the inclined ejector guide and the template 200 during ejection. A fixing block 800 is provided on the lower ejector plate 500. The inclined ejector guide is installed on the fixing block 800. Mounting grooves are provided on the upper ejector plate 400, the lower ejector plate 500 and the lower fixing plate 600. A first screw 900 and a second screw 1000 are provided on the inclined ejector guide. The inclined ejector guide is fixed to the fixing block 800 by the first screw 900. The fixing block 800 is fixed to the lower ejector plate 500 by the second screw 1000.

[0013] As an optimization, the mounting groove of the upper ejector plate 400 is the first mounting groove 1001, and the mounting groove of the lower ejector plate 500 is the second mounting groove 1002. The first mounting groove 1001 and the second mounting groove 1002 are interconnected. The groove width is the width of the inclined ejector guide seat + 2mm, and the groove length is the length of the inclined ejector guide seat in the direction of movement + X1. X1 is the movable clearance of the mounting groove of the first mounting groove 1001, which should be selected so that the inclined ejector guide seat can be connected and installed with the end bracket of the inclined ejector after it extends into the upper and lower ejector plates 500 (X1 is greater than X). The mounting groove of the lower fixing plate 600 is the third mounting groove 1003. The third mounting groove 1003 is connected to the bottom of the lower ejector plate 500, and the width of the third mounting groove 1003 is greater than the width of the fixing block 800. X3 is usually taken as the length or width of the fixing block 800 + 4mm, that is, the mounting through hole is 4mm away to facilitate the installation of the inclined ejector guide and the fixing block 800. Due to the existence of the first mounting groove 1001, the second mounting groove 1002 and the third mounting groove 1003, the installation or disassembly can be carried out by extending into the mold from the bottom.

[0014] During installation, the first step is to insert the angled ejector into the mold from the front (top of the diagram). The second step is to extend the angled ejector guide slide from the third mounting slot 1003 at the bottom of the view into the mold and connect it with the T-shaped mounting platform of the angled ejector. The third step is to insert the fixing block 800 from the third mounting slot 1003, use the first screw 900 to lock the angled ejector seat and the fixing block 800 together, and use the second screw 1000 to fix the fixing block 800 to the lower ejector plate 500. The installation is then complete.

[0015] During disassembly, insert the first screw 900 and the second screw 1000 into the third mounting slot 1003, remove the fixing block 800, and then use the mounting gap X1 of the first mounting slot 1001 to move the inclined top guide slide to the right until the inclined top guide slide comes off the T-shaped bracket of the inclined top. Then it can be removed from the third mounting slot 1003 at the bottom of the view. At this time, the inclined top is no longer restricted by the connection and can be removed from the front of the mold to complete the disassembly.

[0016] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications to the described specific embodiments or adopt similar methods to replace them, but without departing from the scope defined by the spirit of this utility model.
