Description

Technical Field

[0001] This utility model relates to the field of plastic mold core pulling technology, and in particular to a composite multi-angle direction core pulling ejection mechanism. Background Technology

[0002] Existing plastic molds are a general term for a combination of plastic molds used for compression molding, extrusion molding, injection molding, blow molding, and low-foaming molding. All kinds of tools and products we use in our daily production and life, from the base and housing of machine tools to a small screw, button, and the housing of various household appliances, are closely related to molds. The shape of the mold determines the shape of these products, and the processing method and precision of the mold determine the quality of these products.

[0003] However, traditional demolding and core-pulling mechanisms are limited to a single direction or a fixed angle. For some plastic products with complex structures such as inclined oil channels and air channels, such as automotive parts, the mold cannot achieve multi-angle and compound-direction core-pulling, which affects the molding accuracy and demolding smoothness. Utility Model Content

[0004] The present invention proposes a composite multi-angle direction core pulling ejection mechanism, which solves the existing problems.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a composite multi-angle direction core-pulling ejection mechanism, comprising:

[0006] The first motion slider is used to perform a lateral core-pulling motion during the mold opening and closing process;

[0007] The second motion slider is connected below the first motion slider, and the second motion slider is used to perform a core-pulling motion obliquely along the mold opening and closing direction during the mold opening and closing process;

[0008] The fixing mechanism includes a first fixed slide, a second fixed slide, and a third fixed slide. A first moving slider is connected to one side of the first fixed slide, a second moving slider is connected to one side of the second fixed slide, and the first fixed slide is connected above the second fixed slide. The third fixed slide is connected below the first and second fixed slides, and the third fixed slide is used as a base for overall installation.

[0009] Preferably, the first moving slider is connected in parallel to the first fixed slide, and one end of the first moving slider is provided with a connecting protrusion, and the connecting protrusion is in contact with one side of the fixing mechanism.

[0010] Preferably, the fixing mechanism has raised steps on both sides of its lower end, the first fixing slide is in contact with the second fixing slide above, and a first slot is provided on one side of the fixing mechanism, which matches one end of the first moving slider.

[0011] Preferably, the second motion slider has a folded structure, a horizontal square groove is provided at the upper end of the second motion slider, and the first motion slider is engaged and connected inside the square groove, and a second fixed slide block is connected to one side of the second motion slider through a connecting block.

[0012] Preferably, square bars are connected to both sides of the upper end of the second fixed slide, and a first locking block is connected to one side of the lower end of the second fixed slide, and the first locking block is connected to the second moving slider.

[0013] Preferably, the third fixed slide has a groove inside, and a second fixed slide and a second fixed slide are connected in sequence above the groove, and the groove inside the third fixed slide has a trapezoidal inclined structure.

[0014] The beneficial effects of this utility model are as follows: The device mounts the first moving slider parallel to one side of the first fixed slide and the second moving slider to one side of the second fixed slide. The force is transmitted to the first fixed slide through the mold opening and closing mechanism, causing it to move parallel to the first fixed slide to a sufficient demolding stroke. Subsequently, the second fixed slide moves along the inclined direction under the drive of the inclined structure below the third fixed slide, and performs core pulling motion from multiple angles. This effectively solves the problem of inconvenient demolding of complex plastic products and significantly improves demolding efficiency and product quality. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-6 A composite multi-angle core-pulling ejection mechanism includes a first motion slider 1, which performs a lateral core-pulling motion during mold opening and closing; a second motion slider 2, which is connected below the first motion slider 1 and performs an oblique core-pulling motion along the mold opening and closing direction during mold opening and closing; and a fixing mechanism 3, which includes a first fixing slide 301, a second fixing slide 302, and a third fixing slide 303, with the first motion slider connected to one side of the first fixing slide 301. 1. A second fixed slide block 2 is connected to one side of the second fixed slide block 302, and a first fixed slide block 301 is connected above the second fixed slide block 302. A third fixed slide block 303 is connected below the first fixed slide block 301 and the second fixed slide block 302. The third fixed slide block 303 is used as the base for overall installation. The first moving slide block 1 in the horizontal direction and the second moving slide block 2 in the oblique direction perform core pulling movements according to the preset sequence and stroke when the mold is opened and closed through their respective fixed slide blocks, so as to realize the smooth demolding of plastic products.

[0024] Reference Figure 2 , Figure 4 The first moving slider 1 is connected in parallel to the first fixed slide 301, and a connecting protrusion is provided at one end of the first moving slider 1. The connecting protrusion is in contact with one side of the fixed mechanism 3. The lower end of the fixed mechanism 3 is provided with raised steps 304 on both sides. The upper part of the first fixed slide 301 is in contact with the second fixed slide 302. A first slot 305 is provided on one side of the fixed mechanism 3. The first slot 305 matches one end of the first moving slider 1. The first slot 305 and one end of the first moving slider 1 are connected by mutual cooperation. The raised steps 304 are engaged to block the lower side of the square bar 306 for easy assembly. The first moving slider 1 moves laterally. The direction of movement is usually perpendicular to or at a certain angle to the opening and closing direction of the mold, so as to smoothly extract the transverse holes, grooves or concave and convex shapes in the product.

[0025] Reference Figure 3 , Figure 4The second moving slider 2 has a folded structure. A horizontal square groove 201 is formed at the upper end of the second moving slider 2, and the first moving slider 1 is engaged inside the square groove 201. A second fixed slide block 302 is connected to one side of the second moving slider 2 via a connecting block. Square bars 306 are connected to both sides of the upper end of the second fixed slide block 302, and a first locking block 307 is connected to one side of the lower end of the second fixed slide block 302. The first locking block 307 is interconnected with the second moving slider 2. A groove is formed inside the third fixed slide block 303, and the second and third fixed slide blocks 302 are sequentially connected above the groove. The groove inside the third fixed slide block 303 has a trapezoidal inclined structure. (Refer to...) Figure 5 , Figure 6 The force is transmitted to the first fixed slide block 301 through the transmission mechanism, which drives the first horizontal movement slider 1 to move in parallel. After reaching the preset stroke, it drives the second fixed slide block 302 and the second oblique movement slider 2 to move obliquely along the third fixed slide block 303. The oblique core pulling action can ensure that plastic parts with inclined oil channels, air channels or other oblique features in the product can be demolded smoothly.

[0026] The mold material is made of high-strength alloy steel, and the mold material is heat-treated to improve its comprehensive mechanical properties. Through the heat treatment process, the hardness and wear resistance of the mold are improved, and the service life of the mold is extended to meet the requirements of long-term core pulling operation.

[0027] Working principle: First, the drive mechanism (not explicitly shown in the attached diagram, but part of a conventional mold structure) transmits force to the first fixed slide 301. The first fixed slide 301 then moves according to a preset sequence and precision, driving the first horizontal moving slider 1 to perform a core-pulling movement in the horizontal direction under the action of the mold opening and closing force. Subsequently, the second moving slider 2, driven by the second fixed slide 302, moves obliquely along the inclined structure at the bottom of the third fixed slide 303. Throughout the core-pulling process, high-precision processing equipment and assembly technology are used to ensure that the gap between the slider and the guide rail is controlled at approximately 0.02-0.05mm, and the oblique angle error does not exceed ±0.01°, thereby ensuring the smoothness and accuracy of core pulling.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
