Abstract
Description
Technical Field
[0001] This invention belongs to the field of preform injection molding technology, specifically relating to a semi-mold lip component with parallel cooling water channels. Background Technology
[0002] Existing cooling structures for semi-mold lip components mostly employ integral straight-through water channels or independent single-section cooling water channel structures. The overall cooling water channel structure is simple, often a single-layer cavity design, and each cooling area is typically independently located and not interconnected, providing only a basic cooling effect for the entire mold. However, this results in several shortcomings during actual use: Firstly, the heat load varies in different areas of the semi-molded lip forming cavity. The heat load is high and the heat dissipation demand is high in the area where the melt is concentrated, while the heat load in the edge area is relatively small. Traditional integral water channels cannot be used to adapt cooling to different heat load areas, which can easily cause large temperature differences and uneven temperature distribution in the overall cooling of the mold. Secondly, the cooling coverage of a single-layer water channel is limited, and the cooling effect on the deep area of the molding cavity is weak, with obvious cooling blind spots, and local heat accumulation cannot be dissipated quickly. Third, the independent layout of each cooling zone results in poor water flow and the inability of the cooling medium to circulate in an orderly manner. Some water channels have slow flow rates and severe stagnation, which not only leads to low cooling efficiency but also causes uneven heating and cooling of the mold and local stress concentration. Long-term use can easily lead to deformation and wear of the mold lip components, shortening the service life of the mold.
[0003] In summary, existing cooling channels for semi-mold lip components suffer from technical problems such as poor cooling targeting, incomplete coverage, weak circulation heat dissipation, and poor temperature uniformity. These issues make it difficult to meet the continuous molding production requirements of high-precision and high-efficiency plastic products. The industry urgently needs a semi-mold lip cooling channel structure that can achieve zoned differentiated cooling, multi-layer full-coverage heat dissipation, and orderly interconnected circulation of water channels to address the shortcomings of existing technologies. Summary of the Invention

At least one set of two adjacent cooling zones are connected in parallel, and at least one cooling zone includes multiple cooling segments.
[0006] Furthermore, the multi-layer cooling sections within the same cooling zone are connected in series or in parallel.
[0007] Furthermore, the interlayer spacing of the multi-layer cooling segments within the same cooling zone is the same.

[0009] Furthermore, the molding cavity includes a preform molding cavity for molding the preform body and a handle molding cavity for molding the preform handle, and the cooling channel includes a preform cooling zone for cooling the preform molding cavity and a handle cooling zone for cooling the handle molding cavity. The blank body cooling zone and the handle cooling zone are connected in parallel. The billet cooling zone includes multiple cooling sections connected in series; The handle cooling zone includes one or more cooling sections; When the handle cooling zone includes multiple cooling segments, the multiple cooling segments are connected in parallel, and the interlayer spacing of the handle cooling zone is smaller than the interlayer spacing of the billet cooling zone.
[0010] Furthermore, the forming cavity includes a preform mouth forming cavity for forming the preform mouth, a preform body forming cavity for forming a portion of the preform body, and a handle forming cavity for forming the preform handle. The cooling channel includes a preform mouth cooling zone for cooling the preform mouth forming cavity, a preform body cooling zone for cooling the preform body forming cavity, and a handle cooling zone for cooling the handle forming cavity. The blank body forming cavity, the blank opening forming cavity, and the handle forming cavity are connected in parallel in sequence. The billet cooling zone includes multiple cooling sections connected in series; The billet cooling zone includes multiple cooling sections connected in parallel. The interlayer spacing of the billet opening cooling zone is smaller than the interlayer spacing of the billet body cooling zone; The handle cooling zone includes one or more cooling sections; When the handle cooling zone includes multiple cooling segments, the multiple cooling segments are connected in parallel, and the interlayer spacing of the handle cooling zone is smaller than the interlayer spacing of the billet cooling zone.
[0011] Furthermore, between two cooling zones connected in parallel, at least two cooling sections are connected separately.
[0012] Furthermore, a series connection of multiple cooling segments is adopted, with adjacent cooling segments connected end to end by a transition cooling segment; The multi-layer cooling sections are connected in parallel, and adjacent cooling sections are connected by multiple transition cooling sections.
[0013] Furthermore, the semi-molding lip component includes a large mold lip plate and a first flange and a second flange respectively disposed on both ends of the large mold lip plate; the semi-molding lip component also has an inlet channel and an outlet channel extending inward from the surface of the large mold lip plate; The water inlet channel is connected to one of the cooling sections of the first cooling zone, and the water outlet channel is connected to one of the cooling sections of the last cooling zone.
[0014] Furthermore, the molding cavity extends from the end face of the first flange to the end face of the second flange; Alternatively, the parting surface of the semi-molded lip component may also be provided with a mating cavity, and the mating cavity and the molding cavity may be arranged sequentially between the end faces of the first flange and the second flange.
[0015] The beneficial effects of this invention are as follows: This invention divides the cooling water channel into multiple independent and connected cooling zones, and configures the cooling zones according to the differences in heat load in different areas of the molding cavity, so as to achieve differentiated and precise cooling for each zone; adjacent cooling zones adopt a parallel connection structure, which can balance the medium flow rate and pressure of each water channel branch, avoid the problems of local medium stagnation, slow flow rate, and stagnant water accumulation, and ensure continuous, rapid, and uniform circulation of cooling medium for heat exchange, thus greatly improving the overall cooling efficiency; at the same time, each cooling zone is equipped with multi-layer cooling sections, and the same cooling zone can be connected in series or in parallel according to the working conditions, effectively expanding the cooling coverage area, improving the overall cooling efficiency of the mold, and shortening the preform cooling and shaping time.

If the specific posture changes, the directional indicators will also change accordingly.
[0019] Furthermore, unless otherwise explicitly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection using welding, a detachable connection using bolts, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0020] Furthermore, if the embodiments of the present invention involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.
[0021] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this invention. Example 1:
[0022] like Figure 1 and Figure 2 As shown, this embodiment discloses a semi-mold lip component with parallel cooling channels. The parting surface 1 of the semi-mold lip component is provided with a molding cavity 2 for product molding. The semi-mold lip component is embedded with a dedicated cooling channel 3 structure, which is used to precisely and uniformly cool the molding area of the molding cavity 2, so as to ensure the molding quality of the product and avoid problems such as molding warping, uneven shrinkage, and surface defects.
[0023] In this embodiment, the cooling water channel 3 includes two sequentially connected cooling zones 31 for cooling different locations within the molding cavity. To adapt to the cooling needs of different molding areas, adjacent cooling zones 31 are connected in parallel, effectively reducing the water flow resistance of a single channel and improving the overall cooling medium flow efficiency. Simultaneously, to further increase the cooling heat exchange area and improve cooling throughput, the cooling zone 31 is internally equipped with multiple cooling segments 311, which enhance the cooling effect in local areas through the multi-layered flow channel structure.
[0024] Specifically, in the two sets of cooling zones 31 connected in parallel, at least two corresponding cooling segments 311 are connected one-to-one to ensure uniform water flow in the parallel channels and avoid flow deviation or uneven flow. Within the same cooling zone 31, multiple cooling segments 311 are connected end-to-end in series, and the spacing between each cooling segment 311 within the same cooling zone 31 remains consistent, resulting in a regular flow channel arrangement and stable cooling medium flow. Multiple cooling segments 311 within the same cooling zone 31 are connected end-to-end through a single transition cooling segment 312, making the internal cooling water channel 3 structure simple and with good flow conductivity. Furthermore, the spacing between the multiple cooling segments 311 in different cooling zones 31 is also the same.
[0025] Further refining the overall structure of the semi-molding lip component, this embodiment includes a large mold lip plate 4, and a first flange 5 and a second flange 6 respectively fixedly disposed on the end faces of the large mold lip plate 4. The first flange 5 and the second flange 6 are symmetrically arranged, and the molding cavity 2 extends from the end face of the first flange 5 to the end face of the second flange 6. The semi-molding lip component also has an inlet channel 7 and an outlet channel 8, both extending inward from the end face of the large mold lip plate 4. The inlet channel 7 is connected to one layer of cooling section 311 of the first cooling zone 31 for inputting a low-temperature cooling medium; the outlet channel 8 is connected to one layer of cooling section 311 of the last cooling zone 31 for outputting a high-temperature cooling medium after heat exchange, forming a complete cooling circulation loop.
[0026] This embodiment uses a water channel structure of "parallel connection in zones + multi-layer series connection within zones" to balance overall water flow efficiency and local cooling stability, resulting in low flow channel pressure loss and significantly improved overall cooling uniformity of the molding cavity 2. Example 2:
[0027] The specific implementation content of this embodiment is largely the same as that of Embodiment 1, the difference being: Figure 3 As shown, in this embodiment, the interlayer spacing between the cooling segments 311 within the same cooling zone 31 is different. The interlayer spacing of each cooling segment 311 can be adjusted specifically according to the differences in molding thickness, heat dissipation load, and molding temperature at different locations in the half-mold lip forming cavity 2. For areas with high molding temperatures and high heat dissipation requirements, the interlayer spacing of the cooling segments 311 is reduced, the cooling channels are densified, and the heat exchange frequency and cooling efficiency are increased. For areas with low molding temperatures and low heat dissipation requirements, the interlayer spacing of the cooling segments 311 is appropriately increased to simplify the channel structure, reduce the difficulty of mold processing, and avoid energy waste caused by over-cooling. Example 3:
[0028] The specific implementation content of this embodiment is largely the same as that of Embodiment 1, the difference being: Figure 4 As shown, in this embodiment, the connection form of the cooling segments 311 within a single cooling zone 31 is changed. The multi-layer cooling segments 311 within the same cooling zone 31 are connected in parallel instead of the series connection in Embodiment 1, which greatly improves the local cooling throughput.
[0029] Among them, the interlayer spacing between each cooling segment 311 within the same cooling zone 31 is uniformly set to the same size to ensure the regularity of the flow channel; at the same time, the multi-layer cooling segments 311 within the same cooling zone 31 are interconnected through multiple transition cooling segments 312. The multi-channel conduction structure can effectively disperse the medium flow velocity, reduce the flow channel resistance, avoid the problem of blockage and flow restriction in a single transition channel, and ensure the stable flow of cooling medium.
[0030] Furthermore, to address the issue of uneven water inflow and outflow in the multi-layer parallel water channels, this embodiment adds a transition water channel 9 structure inside the half-mold lip component. The inlet water channel 7 is connected to one of the cooling segments 311 of the first cooling zone 31 through the transition water channel 9, and the outlet water channel 8 is connected to one of the cooling segments 311 of the last cooling zone 31 through the transition water channel 9. The transition water channel 9 enables uniform distribution and convergence of the cooling medium, avoiding flow deviation in the multi-layer parallel cooling segments 311.
[0031] Specifically, the transition channel 9 includes a slow-flow channel 91 and at least two branch channels 92. The inlet channel 7 and the outlet channel 8 are respectively connected to the corresponding slow-flow channel 91. The slow-flow channel 91 can buffer and stabilize the cooling medium, eliminate the pulse pressure of the medium flow, and ensure smooth water flow. The slow-flow channel 91 is connected to the cooling section 311 through at least two branch channels 92. By distributing the flow evenly through multiple branch channels 92, the uniformity of water flow in each layer of the cooling section 311 is further improved, ensuring consistent cooling effect.
[0032] This embodiment adopts a "multi-layer parallel connection within a zone + transitional voltage stabilization and diversion" structure, which has a large cooling medium flow rate, high heat exchange efficiency, and strong flow channel stability, making it suitable for production conditions with high heat dissipation load and high-speed molding. Example 4:
[0033] The specific implementation content of this embodiment is largely the same as that of embodiments 1-3, the difference being: Figure 5 and Figure 6 As shown, in this embodiment, the forming cavity 2 includes a preform opening forming cavity 21 for forming the preform opening and a preform body forming cavity 22 for forming part of the preform body; the cooling channel 3 includes a preform opening cooling zone 32 for cooling the preform opening forming cavity 21 and a preform body cooling zone 33 for cooling the preform body forming cavity 22. The preform opening cooling zone 32 and the preform body cooling zone 33 are connected in parallel and each includes multiple cooling sections 311.
[0034] Specifically, since the billet cooling zone 32 corresponds to the billet forming area, which has a complex structure, high forming accuracy requirements, concentrated heat load, and narrow area, the layer spacing between the cooling segments 311 in the billet cooling zone 32 is the same, and the cooling segments 311 are connected in parallel. Furthermore, the small layer spacing is densely arranged, and the multi-layer water channels fully cover and wrap the billet forming area, with no cooling blind spots. The parallel flow distribution structure can achieve rapid temperature uniformity at the billet, ensuring the roundness, dimensional accuracy, and flatness of the bottle mouth.
[0035] The billet cooling zone 33 corresponds to the billet forming area, which has a large forming area, a large melt filling volume, a long solidification and heat dissipation time, and an overall heat load much higher than the billet opening area. Therefore, in the billet cooling zone 33, the multi-layer cooling segments 311 are connected in series, and the spacing between each cooling segment 311 is uniform. Moreover, the spacing between the layers of the billet opening cooling zone 32 is significantly smaller than that of the billet cooling zone 33, which is suitable for the different heat dissipation needs of the large and small areas. The series structure effectively extends the flow path of the cooling medium in the billet area, fully removes the heat of solidification of the large area of melt, and avoids defects such as local heat accumulation, forming shrinkage marks, and uneven wall thickness in the billet. Example 5:
[0036] The specific implementation content of this embodiment is largely the same as that of embodiment 4, the difference being: Figure 7 and Figure 8 As shown, in this embodiment, the molding cavity 2 includes a preform molding cavity 22 for molding the preform body and a handle molding cavity 24 for molding the preform handle. The handle molding cavity 24 is connected to the preform molding cavity 22. The cooling channel 3 includes a preform cooling section 33 for cooling the preform molding cavity 22 and a handle cooling section 35 for cooling the handle molding cavity 24. The preform cooling section 33 and the handle cooling section 35 are connected in parallel and both include multiple cooling sections 311.
[0037] Specifically, since the preform cooling zone 33 corresponds to the preform body forming area, the melt filling volume is large and the overall heat load is high, requiring continuous and stable heat dissipation to ensure the flatness of the main body forming, the interlayer spacing between the cooling segments 311 in the preform cooling zone 33 is the same, and the cooling segments 311 are connected in series; the interlayer spacing in the preform cooling zone 33 is uniform and the value is relatively large, achieving efficient heat dissipation of the main body area through long heat exchange stroke and large heat exchange capacity, avoiding overall deformation caused by large area heat accumulation.
[0038] The handle forming cavity 24 is an irregularly shaped thin-walled structure with uneven wall thickness, complex structure, and significant stress concentration. It is highly susceptible to cracking, deformation, and thickness deviation due to uneven cooling. Therefore, the handle cooling zone 35 and its multiple cooling segments 311 are connected in parallel, with uniform and densely spaced layers. The layer spacing of the handle cooling zone 35 is significantly smaller than that of the blank body cooling zone 33. This parallel dense-layer structure enables synchronous and rapid cooling of the entire irregularly shaped handle, uniformly releasing the internal stress during forming, and completely solving the industry pain points of uneven cooling and low yield of irregularly shaped thin-walled structures. Example 6:
[0039] The specific implementation content of this embodiment is largely the same as that of embodiment 5, the difference being: Figure 9 and Figure 10As shown, in this embodiment, the forming cavity 2 includes a preform mouth forming cavity 21 for forming the preform mouth, a preform body forming cavity 22 for forming part of the preform body, and a handle forming cavity 24 for forming the preform handle. The handle forming cavity 24 is connected to the preform body forming cavity 22. The cooling channel 3 includes a preform mouth cooling zone 32 for cooling the preform mouth forming cavity 21, a preform body cooling zone 33 for cooling the preform body forming cavity 22, and a handle cooling zone 35 for cooling the handle forming cavity 24. The preform mouth cooling zone 32, the preform body cooling zone 33, and the handle cooling zone 35 are connected in parallel in sequence, and each includes multiple cooling segments 311 to achieve differentiated cooling across the entire domain.
[0040] Specifically, in the billet cooling zone 32 and the handle cooling zone 35, the cooling segments 311 within each cooling zone 31 are connected in parallel, and the layer spacing between the cooling segments 311 is the same. In the billet body cooling zone 33, the layer spacing between the cooling segments 311 is the same, and the cooling segments 311 are connected in series. The layer spacing of the multi-layer cooling segments 311 in the billet cooling zone 32 and the handle cooling zone 35 is smaller than the layer spacing of the multi-layer cooling segments 311 in the billet body cooling zone 33. By independently configuring the connection form and layer spacing of the cooling segments 311 in the billet cooling zone 32, the billet body cooling zone 33, and the handle cooling zone 35, each cooling zone 31 can perform adaptive cooling for different parts of different molding cavities 2, ensuring the molding quality of the molded product. Example 7:
[0041] The specific implementation content of this embodiment is largely the same as that of embodiments 5 and 6, the difference being: Figure 11 As shown, in this embodiment, the handle cooling partition 35 includes a cooling segment 311, which conforms to the handle forming cavity 24 to adapt to the structure of the handle forming cavity 24 and provide uniform and sufficient cooling for the handle forming cavity 24. Example 8:
[0042] The specific implementation content of this embodiment is roughly the same as that of embodiments 1-3. The difference is that, in this embodiment, according to the differences in the molding structure at different positions of the molding cavity 2, the cooling segments 311 of different cooling zones 31 are set with different layer spacings to adapt to different cooling requirements. Example 9:
[0043] The specific implementation content of this embodiment is largely the same as that of embodiments 1-8, the difference being: Figure 12 As shown, in this embodiment, the inlet channel 7 and the outlet channel 8 extend inward from both sides of the mold lip plate 4 to accommodate the requirement that the injection mold is configured with connecting water channels on the side of the mold lip plate 4. Example 10:
[0044] The specific implementation content of this embodiment is largely the same as that of embodiments 1-8, the difference being: Figure 13 As shown, in this embodiment, the parting surface of the half mold lip component is also provided with a mating cavity 11. The mating cavity 11 and the molding cavity 2 are arranged sequentially between the end faces of the first flange 5 and the second flange 6. The mating cavity 11 is used to mate with the mold core part (mold core or mold core sleeve) in the molding assembly to meet different molding assembly configurations. Example 11:
[0045] The specific implementation content of this embodiment is roughly the same as that of embodiments 1-10. The difference is that in this embodiment, the water inlet channel 7 and the water outlet channel 8 of the above embodiments are interchanged, that is, the water inlet channel 7 is used as the water outlet channel 8, and the water outlet channel 8 is used as the water inlet channel 7, and the corresponding flow direction of the cooling medium is opposite.
[0046] The above description is only a preferred embodiment of the present invention. Any technical solution that achieves the purpose of the present invention by essentially the same means is within the protection scope of the present invention.
