Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection molding equipment technology, and in particular to a fixed template for an injection molding machine. Background Technology
[0002] Injection molding machines are the main molding equipment used to produce castings of various shapes using molds. Commonly used injection molding machines include two-platen injection molding machines. In a two-platen injection molding machine, the fixed platen and the moving platen are connected by four tie rods, and the moving platen can move along the tie rods. The fixed platen is used to fix the stationary mold, and the moving platen is used to fix the moving mold.
[0003] During the compression molding process, the fixed mold plate remains stationary while the movable mold plate moves along the tie rod and presses against it, thus ensuring a tight fit between the moving and fixed molds. At this point, the moving and fixed molds press against each other, with the center of the fixed mold plate under pressure and the four corners under tension, causing significant deformation. Excessive deformation will affect the quality of the injection molded product, and greater deformation leads to greater stress. When the stress exceeds the allowable stress of the mold plate material, it can cause the mold plate to crack and fail, resulting in economic losses. Current technology typically uses thickened mold plates to strengthen them and reduce deformation and stress. However, this method increases the consumption of mold plate material, thereby increasing processing and transportation costs. Utility Model Content

The plurality of first reinforcing members are connected to the plurality of connecting members one by one, and the end of each first reinforcing member away from the connecting member is connected to the injection channel. A second reinforcing member is arranged between any two adjacent connecting members. The first reinforcing members, the second reinforcing members, and the outer wall of the injection channel form a first chamber.

[0022] The beneficial effects of this utility model are:
[0023] This invention provides a fixed mold for an injection molding machine, including a first panel, a second panel, a connector, an external reinforcing member, an internal reinforcing component, and a boss. The internal reinforcing component provides support for both the first and second panels and improves the overall strength of the fixed mold. The external reinforcing member, circumferentially surrounding the first and second panels, further enhances the rigidity of the fixed mold and improves its resistance to deformation. When the fixed mold is under stress, the stress distribution is more uniform, preventing stress concentration and increasing its load-bearing capacity. During compression molding, the moving mold and the fixed mold press against each other, causing the pressure exerted by the moving mold on the fixed mold to act on the fixed mold, leading to a tendency for deformation. The boss on the second panel increases the thickness of the fixed mold, thereby strengthening its bending resistance, reducing deformation, and preventing cracking and failure. Furthermore, the boss only surrounds the second injection hole circumferentially, increasing the mold thickness in the main pressure area, meeting bending resistance requirements while reducing material consumption and lowering processing costs.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0038] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0039] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0040] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0041] This embodiment provides a fixed template for an injection molding machine, such as... Figures 1 to 6 As shown, this can reduce the deformation of the fixed template, prevent the fixed template from cracking and failing, and also reduce material consumption and processing costs.
[0042] The fixed template of the injection molding machine includes a first panel 1, a second panel 2, connecting parts 3, external reinforcing parts 4, internal reinforcing components 5, and bosses 6. The first panel 1 has a first injection hole 11 and is configured to mount a fixed mold for the injection molded product. The fixed mold communicates with the first injection hole 11. When the injection molding machine opens and closes the mold, the moving mold mounted on the moving template squeezes the fixed mold, ensuring a tight fit between the moving and fixed molds to form an injection cavity. The second panel 2 is axially spaced from the first panel 1 along the first injection hole 11 and has a second injection hole 21 facing the first injection hole 11. An injection channel 22 is provided between the first panel 1 and the second panel 2, and the second injection hole 21 communicates with the first injection hole 11 through the injection channel 22. When the moving and fixed molds are tightly fitted, the material to be processed can be injected into the injection cavity through the second injection hole 21, the injection channel 22, and the first injection hole 11. Multiple connecting parts 3 are provided, spaced circumferentially along the injection channel 22. One end of the connector 3 is connected to the first panel 1, and the other end is connected to the second panel 2. The connector 3 has a mounting through hole 31, which extends axially along the first injection hole 11 and passes through the first panel 1 and the second panel 2. The mounting through hole 31 is used to mount the tie rod of the injection molding machine. An external reinforcing member 4 surrounds the first panel 1 and the second panel 2 circumferentially. An internal reinforcing component 5 is disposed between the first panel 1 and the second panel 2, and is connected to both the external reinforcing member 4 and the injection channel 22. A boss 6 is disposed on the second panel 2, protruding in a direction away from the second panel 2, and surrounds the second injection hole 21 circumferentially.
[0043] By setting the internal reinforcing component 5, support can be provided for the first panel 1 and the second panel 2, and the overall strength of the fixed template can be improved. The external reinforcing component 4 surrounding the first panel 1 and the second panel 2 further enhances the overall rigidity of the fixed template, improves its resistance to deformation, and ensures uniform stress distribution when the fixed template is under stress, avoiding stress concentration and improving its load-bearing capacity. During the pressing process, the moving mold and the fixed mold press against each other, causing the pressure generated by the moving mold on the fixed mold to act on the fixed template, making it prone to deformation. By setting the boss 6 on the second panel 2, the thickness of the fixed template can be increased, thereby enhancing its bending resistance, reducing deformation, and preventing cracking failure. Furthermore, the boss 6 is only surrounding the second injection hole 21, increasing the template thickness in the main pressure area, which meets bending resistance requirements, reduces material consumption, and lowers processing costs.
[0044] In this embodiment, four connectors 3 are provided. In other embodiments, two, three, or more than four connectors 3 may be provided as needed, and no limitation is made here.
[0045] Optionally, such as Figure 1 As shown, the second injection hole 21 is an oblong hole. Compared with a circular hole, opening an oblong hole on the second panel 2 can reduce the diameter of the oblong hole in the short axis direction, thereby reducing the opening area of the second panel 2, improving the bending resistance of the oblong hole in the long axis direction, and thus improving the overall strength of the fixed template.
[0046] Optionally, such as Figure 1 , Figure 3 and Figure 5 As shown, the internal reinforcing component 5 includes multiple first reinforcing members 51 and multiple second reinforcing members 52. The multiple first reinforcing members 51 are spaced apart circumferentially along the injection channel 22, and each of the multiple first reinforcing members 51 is connected to a corresponding number of connecting members 3. The end of each first reinforcing member 51 furthest from the connecting member 3 is connected to the injection channel 22. A second reinforcing member 52 is provided between any two adjacent connecting members 3. By providing the first reinforcing members 51 and the second reinforcing members 52, the connection strength between the first panel 1 and the second panel 2 can be strengthened, the overall rigidity of the fixed template can be improved, and the deformation of the fixed template can be reduced.
[0047] For example, four first reinforcing members 51 and four second reinforcing members 52 are provided. In other embodiments, two, three, or four or more first reinforcing members 51 and second reinforcing members 52 may be provided as needed, and no limitation is made here.
[0048] like Figure 5 As shown, the first reinforcing member 51, the second reinforcing member 52, and the outer wall of the injection channel 22 form a first chamber 511, and the second reinforcing member 52 and the outer reinforcing member 4 form a second chamber 521. The first reinforcing member 51 has a first process hole 512, and two adjacent first chambers 511 are connected through the first process hole 512. The second reinforcing member 52 has a second process hole 522, and the outer reinforcing member 4 has a third process hole 41, which is connected to the first chamber 511 through the second chamber 521 and the second process hole 522. When casting the fixed template, the first process hole 512, the second process hole 522, and the third process hole 41 ensure that its interior is a hollow structure. The first process hole 512 and the second process hole 522 can serve as positioning holes for the internal reinforcing components 5, ensuring that the internal reinforcing components 5 can be formed correctly. When casting the fixed template, sand cores need to be filled, and the third process hole 41 can be used to discharge the internal sand cores, avoiding structural defects in the fixed template. In addition, by setting the first process hole 512, the second process hole 522 and the third process hole 41, the gas generated during the casting process can be discharged, avoiding defects such as porosity in the fixed template.
[0049] Optionally, such as Figure 5As shown, the third process hole 41 is directly opposite the second process hole 522, and the diameter of the third process hole 41 is larger than the diameter of the second process hole 522. This ensures that the fixed template for casting has a better casting process and facilitates the discharge of sand cores from the first chamber 511 and the second chamber 521.
[0050] Optionally, the second reinforcing member 52 includes an arc-shaped reinforcing member. The convex surface of the arc-shaped reinforcing member is tangent to the connecting member 3. When the mold is pressed, the fixed template is under pressure, and the arc-shaped reinforcing member can provide support for the fixed template, reducing its deformation. At the same time, the arc-shaped reinforcing member can disperse the pressure on the fixed template, making the stress distribution on the fixed template uniform, avoiding stress concentration, and preventing damage to the fixed template.
[0051] like Figure 1 , Figure 3 and Figure 5 As shown, the internal reinforcing component 5 also includes a third reinforcing member 53. The third reinforcing member 53 is disposed between the injection channel 22 and the second reinforcing member 52 to divide the first chamber 511 into a first cavity 5111 and a second cavity 5112. The third reinforcing member 53 has a fourth process hole 531, through which the first cavity 5111 and the second cavity 5112 communicate. By providing the third reinforcing member 53 to connect the injection channel 22 and the second reinforcing member 52, the connection strength between the first panel 1 and the second panel 2 can be further strengthened, improving the overall rigidity of the fixed template and ensuring that the fixed template has good bending resistance.
[0052] For example, four third reinforcing members 53 are provided. In other embodiments, two, three, or more than four third reinforcing members 53 may be provided as needed, and no limitation is made here.
[0053] Optionally, such as Figure 1 , Figure 3 and Figure 5As shown, the internal reinforcing component 5 also includes a fourth reinforcing member 54. The fourth reinforcing member 54 is disposed between the second reinforcing member 52 and the external reinforcing member 4 to divide the second chamber 521 into a third cavity 5211 and a fourth cavity 5212. The fourth reinforcing member 54 has a fifth process hole 541, through which the third cavity 5211 and the fourth cavity 5212 communicate. By providing the fourth reinforcing member 54, the internal reinforcing component 5 and the external reinforcing member 4 can be connected, allowing the external reinforcing member 4 to cooperate with the internal reinforcing component 5 to ensure the connection strength of the first panel 1 and the second panel 2, improve the overall rigidity of the fixed template, and reduce the deformation of the fixed template. As can be seen from the above, the first process hole 512, the second process hole 522, the third process hole 41, the fourth process hole 531 and the fifth process hole 541 are interconnected, which can ensure that the sand core filled during casting remains stable and facilitate the discharge of the sand core inside the fixed template. Therefore, it is not necessary to open the sand core outlet hole on the second panel 2, avoid stress concentration at the sand core outlet hole, and improve the crack resistance safety factor of the fixed template.
[0054] For example, four fourth reinforcing members 54 are provided. In other embodiments, two, three, or more than four fourth reinforcing members 54 may be provided as needed, and no limitation is made here.
[0055] It should be noted that the number of connectors 3, the number of first reinforcing members 51, the number of second reinforcing members 52, the number of third reinforcing members 53, and the number of fourth reinforcing members 54 are the same.
[0056] Optionally, the thicknesses of the first reinforcing member 51, the second reinforcing member 52, the third reinforcing member 53, and the fourth reinforcing member 54 decrease sequentially. The thickness of the outer reinforcing member 4 is greater than or equal to the thickness of the fourth reinforcing member 54. When the mold is pressed, the main pressure-bearing area of the fixed template is the injection channel 22. By controlling the thickness of each reinforcing member to decrease sequentially, the weight of the fixed template can be reduced, material consumption can be reduced, and costs can be lowered. Furthermore, the pressure distribution on the fixed template can be made more uniform, ensuring that the overall stress of the fixed template is smaller, and the fixed template also has better bending strength, reducing its deformation.
[0057] In this embodiment, the thickness of the second reinforcing member 52 is 0.4 to 0.6 times the thickness of the first reinforcing member 51, the thickness of the third reinforcing member 53 is 0.35 to 0.4 times the thickness of the first reinforcing member 51, and the thickness of the fourth reinforcing member 54 is 0.25 to 0.3 times the thickness of the first reinforcing member 51.
[0058] Optionally, along the direction away from the second panel 2, the thickness of the protrusion 6 is greater than or equal to the thickness of the second panel 2. By increasing the thickness of the pressure-bearing area of the second panel 2, the bending resistance of the fixed template can be improved, ensuring that the bending resistance requirements of the fixed template are met, reducing the deformation of the fixed template, and preventing the fixed template from cracking and failing.
[0059] For example, the protrusion thickness of the boss 6 is equal to the thickness of the second panel 2.
[0060] Optionally, such as Figure 2 and Figure 4 As shown, the boss 6 includes a tapered boss 6. The thickness of the tapered boss 6 gradually decreases along the direction away from the second injection hole 21. By setting the tapered boss 6, stress concentration can be avoided, the pressure distribution on the second panel 2 can be made uniform, and damage to the second template due to excessive local pressure can be prevented.
[0061] Optionally, such as Figure 1 , Figure 3 and Figure 6 As shown, the mounting through hole 31 includes a first hole segment 311, a second hole segment 312, and a third hole segment 313 connected in sequence. The end of the first hole segment 311 away from the second hole segment 312 passes through the first panel 1, and the end of the third hole segment 313 away from the second hole segment 312 passes through the second panel 2. The second hole segment 312 is provided with a stress-relieving surface 3121. By providing the stress-relieving surface 3121, stress concentration can be avoided, preventing the fixed template from breaking due to excessive local tension.
[0062] In this embodiment, the unloading surface 3121 is conical with a cone angle of 10°.
[0063] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
