Description

Technical Field

[0001] This utility model relates to the field of mold core technology, specifically to a mold core plate and a mold core plate assembly with parallel water flow. Background Technology

[0002] In existing mold core plate assemblies, the mold core plate typically uses an upper and lower cooling flow path for water flow, which has the following drawbacks:

[0003] 1. When cooling water flows in the upper cooling flow path, the mold core cooling pipe will block the cooling water: on the one hand, each blockage will reduce the cooling water flow rate, reduce cooling efficiency, and prolong cooling time; on the other hand, it will lead to uneven cooling, causing surface defects in the product and affecting product quality; furthermore, poor water flow can also easily form scale or cause corrosion, damaging the mold structure.

[0004] 2. The use of upper and lower cooling channels and the thicker mold core plate will directly lead to an increase in material costs, processing costs and processing difficulty, and will also result in a larger weight of the plate, increasing the difficulty of handling and installation, and to a certain extent increasing the burden on equipment and production consumption. At the same time, it may not be suitable for injection molding machines with a smaller maximum mold thickness. Utility Model Content

Detailed Implementation

[0032] The present invention will be further described in detail below with reference to specific embodiments.

[0033] Example 1:

[0034] like Figure 1-2 As shown, this embodiment provides a mold core plate, including: a mold core plate body 1, the mold core plate body 1 having a plurality of mold core component mounting positions 2 arranged in a rectangular array, the mold core component mounting positions 2 being used to mount mold core components 3; wherein, the mold core component mounting positions 2 include a mold core mounting position 21 and a mold core cooling pipe mounting position 22 arranged sequentially from the surface of the mold core plate body into the interior of the mold core plate body 1;

[0035] The mold core mounting position 21 is used to install the mold core 31, and the mold core cooling pipe mounting position 22 is used to install the mold core cooling pipe 32. Inside the mold core plate body 1, a set of cooling flow paths 4 is provided below each row of mold core assembly mounting positions 2. The set of cooling flow paths 4 includes a first cooling flow channel 41 and a second cooling flow channel 42 parallel to the distribution direction of the row of mold core assembly mounting positions 2. The first cooling flow channel 41 is connected to the mold core cooling pipe mounting position 22 through the connecting structure 5, and the second cooling flow channel 42 is connected to the mold core mounting position 21 through the connecting structure 5.

[0036] The connecting structure 5 includes a first water hole 51 and a second water hole 52 located inside the mold core plate body 1. The first water hole 51 connects the mold core cooling pipe mounting position 22 with the first cooling channel 41, and the second water hole 52 connects the mold core mounting position 21 with the second cooling channel 42.

[0037] The number of first water holes 51 is one, which extends from the middle of the bottom surface of the mold core cooling pipe mounting position 22 toward the bottom of the mold core plate body 1.

[0038] The number of second water holes 52 is one or more, extending from the bottom of the mold core mounting position 21 toward the bottom of the mold core plate body 1.

[0039] The downward-extending end of the first water hole 51 is connected to the side of the first cooling channel 41 near the second cooling channel 42; the downward-extending end of the second water hole 52 is connected to the side of the second cooling channel 42 near the first cooling channel 41.

[0040] There is a gap between the radial center axis of the first cooling channel 41 and the longitudinal center axis of the first water hole 51, and there is a gap between the radial center axis of the second cooling channel 42 and the longitudinal center axis of the second water hole 52, so that the first cooling channel 41 and the second cooling channel 42 are staggered and arranged side by side.

[0041] Specifically, both the core mounting position 21 and the core cooling pipe mounting position 22 have circular cross-sections. The radius of the core mounting position 21 is larger than that of the core cooling pipe mounting position 22. The core mounting position 21 and the core cooling pipe mounting position 22 are coaxially arranged, thus forming a stepped structure between them. The plane of the stepped structure is the bottom surface of the core mounting position 21. The second water hole 52 extends from the plane of the stepped structure toward the bottom of the core plate. In this embodiment, there are two second water holes 52. Through the two second water holes 52, the cooling water transported from the space between the core and the core cooling pipe can flow quickly to the second cooling channel 42, or can flow quickly from the second cooling channel 42 to the space between the core and the core cooling pipe.

[0042] In this embodiment, the mold core plate sets the cooling flow path as a first cooling channel 41 and a second cooling channel 42, and connects the first water hole 51 and the second water hole 52 to the mold core cooling pipe mounting position 22 and the mold core mounting position 21 respectively. This ensures that the coolant flows along the following path: first cooling channel 41 - first water hole 51 - internal space of the mold core cooling pipe - space between the mold core cooling pipe and the mold core tube - second water hole 52 - second cooling channel 42 - second water hole 52 of the next connecting structure 5 - space between the mold core cooling pipe and the mold core tube - internal space of the mold core cooling pipe - first water hole 51 - first cooling channel 41; or the reverse of the above flow path. With this setting, the cooling water will not be blocked by the mold core cooling pipe when flowing through the first cooling channel 41 and the second cooling channel 42, ensuring smooth water flow, improving cooling efficiency, and ensuring uniform cooling of the mold core assembly 3, thereby ensuring product quality and reducing the formation of scale or corrosion in the cooling flow path.

[0043] It should be noted that by setting the cooling flow paths to be distributed in parallel, the thickness of the mold core plate can be reduced, thereby reducing material costs, processing costs and processing difficulty, reducing the difficulty of handling and installation, reducing equipment burden and production consumption, and making it suitable for injection molding machines with small spacing.

[0044] Example 2:

[0045] like Figure 3 As shown in the figure, the mold core plate provided in this embodiment has a connecting structure 5 including a water-transporting component 6. The water-transporting component 6 is disposed at the bottom of the mold core assembly mounting position 2, wherein the mold core cooling pipe mounting position 22 is defined by the water-transporting component 6. The water-transporting component 6 includes a first water-transporting channel 61 and a second water-transporting channel 62. The first water-transporting channel 61 connects the mold core mounting position 21 and the first cooling channel 41, and the second water-transporting channel 62 connects the mold core cooling pipe mounting position 22 and the second cooling channel 42.

[0046] Specifically, to facilitate the processing of the mold core plate, an insert groove can be machined below the mold core mounting position 21. The insert groove is connected to the mold core mounting position 21 and also to the first cooling channel and the second cooling channel, respectively. That is, without the water-carrying component 6, the mold core mounting position 21, the first cooling channel, and the second cooling channel are in a connected state. The shape of the water-carrying component 6 is not specifically limited and can be set according to the shape of the insert groove. For example, the insert groove is a cylindrical groove structure, and the water-carrying component 6 is a cylindrical block. By machining the first cooling channel into the water-carrying component 6... The water channel 61, the second water channel 62, and the mold core cooling pipe mounting position 22 are provided. The first water channel 61 and the second water channel 62 can be through holes penetrating the water channel component 6. After the water channel component 6 is fixed in the inlay groove by the first fixing pin 64, the first water channel 61 connects the mold core cooling pipe mounting position 22 with the first cooling channel 41, and the second water channel 62 connects the mold core mounting position 21 with the second cooling channel 42. This achieves the function of the first water hole 51 and the second water hole 52 as in Embodiment 1, and also facilitates the processing of the mold core plate.

[0047] It should be noted that, in order to further ensure the sealing between the water-carrying component 6 and the mold core plate body, a sealing ring 63 is provided between the water-carrying component 6 and the mold core plate body. Parts not mentioned in this embodiment are the same as in Embodiment 1.

[0048] In some embodiments, Figure 4 A mold core plate including another embodiment of the water-carrying component is shown, with Figure 3 The difference shown is that the water transport component 6 does not include the first water transport channel 61, and the second water transport channel 62 is connected to the second cooling channel 42 through the second water hole 52.

[0049] Example 3:

[0050] like Figure 5-6 As shown, the mold core plate provided in this embodiment also includes a flow guiding component 7. The flow guiding component 7 is disposed at the bottom of the mold core mounting position. The flow guiding component 7 has a central hole 72 through which the mold core cooling pipe passes and a flow guiding channel 71 disposed on one side of the central hole 72. The flow guiding channel 71 connects the mold core mounting position with the second water hole 52 or the second water channel 62.

[0051] In implementation, the end face of the flow guiding component 7 facing the mold core is inclined towards the flow guiding channel 71. The cross-section of this end face in the plane passing through the axis of the mold core cooling pipe and the axis of the flow guiding channel is a straight line segment or a curved segment, that is, the end face is a plane or a curved surface, such as a parabola. By setting such a flow guiding component 7, the cooling water located radially farther from the flow guiding channel 71 is guided to flow faster into the flow guiding channel 71, balancing the flow of cooling water in and out of the space between the mold core and the mold core cooling pipe, so that the cooling water flows evenly in the space between the mold core and the mold core cooling pipe, thereby providing uniform cooling for the mold core.

[0052] like Figure 5 As shown, in some embodiments, the flow guiding component 7 is inserted into the bottom of the mold core mounting position and fixed to the mold core mounting position by fixing screws 74. The flow guiding channel 71 connects the mold core mounting position 21 and the second water hole 52. By setting such a flow guiding component 7, it is convenient to guide the cooling water into and out of the space between the mold core and the mold core cooling pipe, ensuring smooth water flow, improving cooling efficiency, and ensuring uniform cooling of the mold core assembly 3, thereby ensuring product quality and reducing the formation of scale or corrosion in the cooling flow path.

[0053] like Figure 6 As shown, in some embodiments, the flow guiding component 7 is inserted into the bottom of the mold core mounting position and, if necessary, fixed to the water transport component 6 by a second fixing pin (not shown in the figure). The flow guiding channel 71 connects the mold core mounting position and the second water transport channel 62. By setting such a flow guiding component 7, it is convenient to guide the cooling water into and out of the space between the mold core and the mold core cooling pipe, ensuring smooth water flow, improving cooling efficiency, and ensuring uniform cooling of the mold core assembly 3, thereby ensuring product quality and reducing the formation of scale or corrosion in the cooling flow path.

[0054] The parts not mentioned in this embodiment are the same as in Embodiment 2.

[0055] Example 4:

[0056] like Figure 7 As shown, this embodiment provides a parallel water-flow mold core plate assembly, including a mold core assembly 3 and a mold core plate. The number of mold core assemblies 3 corresponds to the mold core assembly mounting positions 2, and each mold core assembly mounting position 2 corresponds to the installation of one mold core assembly 3. The mold core assembly 3 includes a mold core 31 and a mold core cooling pipe 32 coaxially mounted inside the mold core.

[0057] The mold core 31 is installed in the mold core mounting position 21, and the mold core cooling pipe passes through the mold core mounting position 21 and is installed in the mold core cooling pipe mounting position 22;

[0058] The first cooling channel 41 can be connected to the internal space of the mold core cooling pipe through the connecting structure 5, and the second cooling channel 42 can be connected to the space between the mold core 31 and the mold core cooling pipe through the connecting structure 5.

[0059] The parallel cooling core plate assembly of this embodiment reduces the thickness of the core plate by setting parallel first cooling channels 41 and second cooling channels 42, while improving cooling efficiency and ensuring uniform cooling of the core plate assembly 3, thereby ensuring product quality.

[0060] The parts not mentioned in this embodiment are the same as in Embodiment 1.

[0061] Example 5:

[0062] The mold core is installed in the mold core mounting position. The mold core cooling pipe passes through the center hole of the mold core mounting position and the flow guide component and is installed in the mold core cooling pipe mounting position. The second cooling channel can be connected to the space between the mold core and the mold core cooling pipe through the flow guide channel of the connecting structure and the flow guide component.

[0063] The parts not mentioned in this embodiment are the same as in Embodiment 3.

[0064] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
