Description

Technical Field

[0001] The present disclosure relates to the technical field of mold manufacturing, and in particular to a mold core structure, a mold, and parts. Background Art

[0002] In modern mold manufacturing, the mold core is the core component of the mold, and its design and structure have a crucial impact on the overall performance and production efficiency of the mold. In traditional mold core designs, the mold core is usually provided with connecting parts in multiple directions to form an installation structure that connects to the slide mechanism. In traditional mold core designs, the mold core is provided with multiple circumferentially spaced connecting parts, each of which needs to be connected to the slide mechanism. Due to the inconsistent directions of the first engaging parts of the connecting parts, a large number of slides are required. This not only increases the complexity of the mold, but also leads to higher manufacturing costs and longer production cycles. Due to the large number of slides and complex structure, the installation process becomes very cumbersome. On-site staff need to spend a lot of time and energy to ensure the correct installation of each connecting part and slide mechanism, which not only increases labor intensity but also prolongs the assembly time of the mold. The coordination of multiple connecting parts and slide mechanisms easily leads to cumulative errors during the manufacturing and installation process, affecting the accuracy and consistency of the mold. This not only affects the quality of the product, but also shortens the service life of the mold. Summary of the Invention

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the context of this disclosure, "a group" means two or more, unless otherwise specifically defined.

[0038] In order to clearly describe the present disclosure, components not related to the description are omitted, and the same or similar components throughout the specification are denoted by the same reference numerals.

[0039] Throughout this specification, when a device is said to be "connected" to another device, this includes not only "direct connection" but also "indirect connection" with other elements interposed therebetween. Furthermore, when a device is said to "include" a certain component, unless otherwise stated, this does not exclude the inclusion of other components but rather implies that the device may include other components.

[0040] Although the terms first, second, etc. are used in this document to represent various elements in some examples, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, the first interface and the second interface, etc. are represented. Furthermore, as used in this document, the singular forms "one," "an," and "the" are intended to also include the plural forms, unless there is a contrary indication in the context. It should be further understood that the terms "comprise" and "include" indicate the presence of the described features, steps, operations, elements, modules, projects, types, and / or groups, but do not exclude the presence, occurrence, or addition of one or a group of other features, steps, operations, elements, modules, projects, types, and / or groups. The terms "or" and "and / or" used herein are interpreted as inclusive, or mean any one or any combination. Therefore, "A, B, or C" or "A, B, and / or C" means "any of the following: A; B; C; A and B; A and C; B and C; A, B, and C."

Terms defined in commonly used dictionaries are additionally interpreted as having meanings consistent with relevant technical literature and the current message. Unless otherwise defined, they should not be overly interpreted as ideal or highly formalized meanings.

[0043] In the prior art, the slide mechanism is connected to the connection portion of the mold core. Therefore, the connection direction and movement direction of the slide mechanism are restricted by the first engaging portions at both ends of the connection portion. In the prior art, the engaging portions at both ends of the connection portion are evenly oriented in eight directions, necessitating the installation of eight corresponding slide mechanisms. Excessive slide mechanisms not only result in less refined parts but also complicate the mold structure. The large number of slide mechanism components also complicates mold assembly.

[0044] In the embodiment of the present disclosure, mounting structures connected to the sliding mechanisms are formed at the four basic positions of the mold core, and the extension direction of the locking portion of the connecting portion in the same mounting structure is set to be straight, so that it is only necessary to set the sliding mechanisms along the number of mounting structures, thereby reducing the number of sliding mechanisms, making the structure of the mold simpler, the parts produced more refined, and reducing the processing time.

[0045] Figure 1 A schematic structural diagram from a first angle of a mold core structure in one embodiment of the present disclosure is shown.

[0046] A second angle structural schematic diagram of a mold core structure in one embodiment of the present disclosure is shown.

[0047] In one embodiment of the present disclosure, a mold core structure is provided, wherein Figure 1 In an embodiment, the mold core structure includes:

[0048] The first mold core 100 has a plurality of connecting portions 101 circumferentially spaced apart thereon to form mounting structures 103 for connecting with the sliding mechanism 200 in four basic directions; both ends of each of the connecting portions 101 are provided with first engaging portions 102 for engaging with the sliding mechanism 200, and the first engaging portions 102 of the connecting portions 101 in the same mounting structure 103 extend in parallel.

[0049] Specifically, in the above embodiment, a plurality of connecting portions 101 are evenly distributed on the periphery of the first mold core 100, and both ends of each connecting portion 101 are provided with a first engaging portion 102 for engaging with the slide mechanism 200. Figure 1 In this example, the first mold core 100 is a circular structure. Optionally, eight connecting portions 101 are arranged along the edge of the first mold core 100. The connecting portions 101 are evenly distributed on the outer periphery of the first mold core 100. Optionally, the inner circle of the first mold core 100 is raised to correspond to the shape of the inner circle of the part, and the connecting portions 101 are distributed along the periphery of the raised circle. The evenly distributed connecting portions 101 form mounting structures 103 in four basic directions, such as Figure 1 In this example, each mounting structure 103 includes four first engaging portions 102. The four first engaging portions 102 are oriented in the same direction and extend along the basic direction. For example, the four upper and four lower first engaging portions 102 extend vertically, while the four left and right first engaging portions 102 extend horizontally. Because the first engaging portions 102 in the same mounting structure 103 are oriented in the same direction, the corresponding sliding mechanism 200 only needs to move along the direction of the mounting structure 103, thereby reducing the number of sliding mechanisms 200.

[0050] Optionally, the structures of the mounting structures 103 in every two opposing basic directions are the same; and / or the structures of the mounting structures 103 in the four basic directions are the same.

[0051] Specifically, in some embodiments, in each of the four cardinal directions, the mounting structures 103 in each pair of opposing cardinal directions are identical. For example, the mounting structures 103 in the 0-degree and 180-degree directions are identical, as are the mounting structures 103 in the 90-degree and 270-degree directions. This symmetrical design not only simplifies the mold manufacturing process but also ensures that the mounting structures 103 in all directions have the same mechanical properties and stability.

[0052] Optionally, the mounting structures 103 in the four basic directions may be configured to have the same structure, which means that the mounting structures 103 in the directions of 0 degrees, 90 degrees, 180 degrees, and 270 degrees are consistent in size, shape, and function.

[0053] Optionally, the mold core structure further includes a second mold core 401 (see Figure 7 ), forming a cavity between the first mold core 100 and the second mold core 401. In some embodiments, the second mold core 401 can be provided on the first mold core 100 with a gap.

[0054] FIG2( a ) shows a schematic structural diagram of a mold at a first angle in an embodiment of the present disclosure.

[0055] FIG2( b ) shows a schematic diagram of the second angle structure of a mold in one embodiment of the present disclosure.

[0056] In another embodiment of the present disclosure, a mold is provided, wherein in the examples of FIG. 2 ( a ) and FIG. 2 ( b ), the mold comprises: the mold core structure described in the above embodiment;

[0057] The four sliding mechanisms 200 are respectively movably mounted on each of the mounting structures 103 along the four basic directions.

[0058] Specifically, in the example of Figure 2 (a), there are two mold core structures and four sliding mechanisms 200 corresponding to each mold core structure. The sliding mechanisms 200 in the corresponding directions are engaged with the first engaging portion 102 in the mounting structure 103. In the example of Figure 2 (b), the first mold core 100 is a protruding structure, and the sliding mechanism 200 can move relatively along the basic direction. The four sliding mechanisms 200 are in a "cross" structure, and the first mold core 100 is arranged in the middle position of the cross structure formed by the sliding mechanisms 200. In other examples, the first mold core 100 can also be set to other shapes, and the corresponding sliding mechanisms 200 can also be set to other shapes. The shape of the first mold core 100 is related to the parts to be manufactured, so the figure is only one example, and first mold cores 100 of other shapes should also be included in the protection scope of this disclosure.

[0059] 3 (a) shows a schematic structural diagram of a mold in an open mold state in one embodiment of the present disclosure.

[0060] FIG3( b ) shows a schematic structural diagram of a mold in a mold-closing state according to an embodiment of the present disclosure.

[0061] In the example of Figure 3 (a), taking the slide mechanism 200 on the opposite side as an example, when the mold needs to be opened, the slide mechanism 200 on the opposite side, due to the restriction of the corresponding mounting structure 103, can move relatively away from the direction of the first engaging portion 102 in the same mounting structure 103 to expose the parts manufactured on the mold core. It should be noted that in the examples of Figures 3 (a) and 3 (b), the mold core does not show the manufactured parts, but only indicates them with text. In the example of Figure 3 (b), when it is necessary to manufacture parts, the slide mechanism 200 on the opposite side is moved relatively closer to engage with the first engaging portion 102 in the corresponding mounting structure 103.

[0062] Figure 4 A schematic structural diagram of a mold in which the first mold core fixing plate 300 is removed is shown in one embodiment of the present disclosure.

[0063] Optionally, in FIG3(a), FIG3(b) and Figure 4 In this example, a single slide mechanism 200 includes: a core 201 on one side, a core fixing seat 202 and a pressing bar 203 .

[0064] FIG5( a ) shows a schematic structural diagram of a slide mechanism 200 in a mold without a mold core placed therein according to an embodiment of the present disclosure.

[0065] FIG5( b ) shows a schematic structural diagram of a mold for displaying the second engaging portion 2011 in one embodiment of the present disclosure.

[0066] In the example shown in Figure 5(a), the side core 201, on the end facing the mold core, is shaped to mate with the outer edge of the mold core structure and is provided with at least one second engaging portion 2011 that engages with the first engaging portion 102. Specifically, to connect the slide mechanism 200 to the connecting portion 101, a second engaging portion 2011 is provided on the side of the side core 201 in the slide mechanism 200 that connects to the connecting portion 101, engaging with the first engaging portion 102. The second engaging portion 2011 is recessed inward to correspond to the convex first engaging portion 102. In other examples, the first engaging portion 102 may be recessed, while the second engaging portion 2011 is convex and engages with the first engaging portion 102. The shapes of the first engaging portion 102 and the second engaging portion 2011 are not limited. Furthermore, to connect with the mold core, the inner sidewall of the end facing the mold core is shaped to mate with the outer edge of the mold core, ensuring a tight fit between the side core 201 and the mold core. In the example of FIG5(b), three second engaging portions 2011 corresponding to the first engaging portions 102 are provided on the inner side wall of the side core 201, wherein the second engaging portions 2011 on the same side core 201 are oriented in the same direction as the corresponding first engaging portions 102.

[0067] In Figure 3(a), Figure 3(b) and Figure 4 In this example, the core fixing seat 202 is provided corresponding to the side core 201 and is provided below the side core 201 .

[0068] Furthermore, the pressing strips 203 are provided on two opposite sides of the core fixing seat 202 to press and fix the side core 201 on the core fixing seat 202 .

[0069] Specifically, the core holder 202 supports and secures the side core 201, ensuring its stability during mold operation and preventing displacement or damage due to vibration or external forces. The hold-down strip 203 provides additional pressure, ensuring close contact between the side core 201 and the mold core, and preventing product defects caused by uneven pressure during the injection molding process.

[0070] Figure 6 A schematic structural diagram of the first mold core fixing plate 300 in one embodiment of the present disclosure is shown.

[0071] Optional, in Figure 6 In the example, the mold further includes:

[0072] The first mold core fixing plate 300 is provided with a mold core fixing area 301 for setting the first mold core 100 and the sliding mechanism 200 .

[0073] The first mold core fixing plate 300 provides a stable platform for installing and fixing the first mold core 100 and the slide mechanism 200. The design of the mold core fixing area 301 ensures the precise positioning and stable installation of the first mold core 100 and the slide mechanism 200, thereby improving the overall stability and reliability of the mold. Figure 6 Furthermore, in this example, the reduction in the number of slides 200 increases the free space between the first mold core 100 and the first mold core fixing plate 300, improving the structural strength and stability of the mold and reducing the risk of deformation and damage. This increased free space enhances the structural strength of the first mold core fixing plate 300, allowing it to better withstand prolonged, intensive use. The appropriately increased size of each slide 200 enhances its structural strength, extending the mold's service life and reducing the frequency of repair and replacement.

[0074] Figure 7 A schematic structural diagram of the second mold core fixing plate 400 in one embodiment of the present disclosure is shown.

[0075] Optional, in Figure 7 In the example, the mold further includes:

[0076] A second mold core fixing plate 400 , on which a shovel base 204 setting area is further provided corresponding to the core fixing seat 202 ;

[0077] The sliding mechanism 200 further includes a shovel base 204 , which is fixed to the shovel base 204 setting area and fixedly connected to the core fixing seat 202 .

[0078] Specifically, in Figure 7 In this example, the shape of the second mold core fixing plate 400 matches that of the first mold core fixing plate 300. A shovel base 204 mounting area is provided on the second mold core fixing plate 400, corresponding to the slide mechanism 200, for securing the shovel base 204. Notably, in Figure 5(b), the shovel base 204 is positioned above the side core 201. A through-hole is provided at a position corresponding to the side core 201 and the shovel base 204. Although not shown in Figure 5(b), this through-hole is actually present. A slide drive guide post 402 is provided on the second mold core fixing plate 400, corresponding to the through-hole. The slide drive guide post 402 passes through the through-holes of the side core 201 and the through-holes of the shovel base 204, securing the shovel base 204 to the side core 201 and then to the core fixing seat 202.

[0079] Optional, in Figure 7 In this example, the mold core structure further includes: a second mold core 401 forming a mold cavity with the first mold core 100. Optionally, the second mold core 401 is fixed to the second mold core fixing plate 400 and is located in the center of the shovel base 204.

[0080] Specifically, since the first mold core 100 is a convex structure, in order to cooperate with the first mold core 100, the second mold core 401 is a concave structure to form a cavity, thereby ensuring the precise molding and high quality of the product.

[0081] In yet another embodiment of the present disclosure, a part is provided, wherein the part is obtained by material injection molding using the mold described in any of the above embodiments.

[0082] The above embodiments are merely illustrative of the principles and effects of this disclosure and are not intended to limit this disclosure. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, any equivalent modifications or alterations made by a person skilled in the art without departing from the spirit and technical concepts disclosed herein shall be encompassed by the scope of protection of this disclosure.
