Description

Technical Field

[0001] The invention relates to the technical field of injection molds, in particular to a transverse single-hole water channel and a water-isolating injection mold device. Background Art

[0002] The water cooling channels of injection molds are divided into double-hole channels and single-hole channels. The double-hole channels refer to through-hole channels with cooling water inlet and outlet. The single-hole channels refer to blind-hole channels that use a baffle to separate the blind hole into two half-channels, where the opening of one half-channel serves as the cooling water inlet and the opening of the other half-channel serves as the cooling water outlet.

[0003] Single-hole water channels are mostly set longitudinally, referred to as longitudinal single-hole water channels. For molds with a large longitudinal projection area of the core, the longitudinal single-hole water channel is point cooling, and the contact area between the point cooling and the core surface is small, resulting in low cooling efficiency of the core surface. In order to achieve sufficient cooling effect, it is necessary to set a large number of longitudinal single-hole water channels for point cooling in the core for cooling. Once the number of longitudinal single-hole water channels is large, it is bound to occupy the internal space of the mold and compete with the ejection and demolding mechanism of the mold for space, resulting in a complex mold structure and high manufacturing costs.

[0004] Some existing single-hole water channels are also arranged horizontally, but their cooling effect is not obvious enough, and the coverage area of the single-hole water channel is small, the heat dissipation is insufficient, and thus the overall cooling effect of the entire mold is affected. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a transverse single-hole water channel and a water-proof injection mold device to solve the problems raised in the above-mentioned background technology.

[0007] A transverse single-hole water channel and water-proof injection mold device, including a mold core, wherein the mold core is provided with a transverse single-hole water channel, a water-proof component and a branch water channel, the water-proof component includes a column, an isolation plate fixedly connected to the column and a partition part, the partition part divides the transverse single-hole water channel into a plurality of main water channels that are not connected to each other, the main water channel and the branch water channel are arranged at intervals, the isolation plate divides the main water channel into a first channel and a second channel, the first channel and the second channel are connected to each other, the second channel between two adjacent main water channels is connected to the first channel through the branch water channel, the partition part is fixed A short plate is fixed on the column, and the short plate is spaced apart from the isolation plate. The short plate divides the horizontal single-hole water channel into multiple main water channels that are not connected to each other, and baffles placed in the main water channel are fixed at both ends of the branch water channel. A second diversion port is provided at one end of the baffle, and the second channel and the first channel between two adjacent main water channels are connected to the branch water channel through the second diversion port and form a triangular flow water channel with the branch water channel; any main water channel is connected to a water inlet and a water outlet, and a first diversion port is provided at the end of the isolation plate away from the column, and the first channel and the second channel are connected through the first diversion port.

DETAILED DESCRIPTION

[0017] The following describes the embodiments of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless they conflict.

[0018] Example 1:

[0019] In the description of the present invention, it should be understood that the terms "up", "down", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0020] Please see the attached Figure 1 and attached Figure 2 As shown, a transverse single-hole water channel and water-proof injection mold device includes a mold core 1, in which a transverse single-hole water channel, a water-proof component 2 and a branch water channel 4 are provided. The water-proof component 2 includes a column 21, an isolation plate 22 fixedly connected to the column 21 and a partition part 23. The partition part 23 divides the transverse single-hole water channel into multiple main water channels 3 that are not connected to each other. The main water channels 3 and the branch water channels 4 are spaced apart. The isolation plate 22 divides the main water channel 3 into a first channel 31 and a second channel 32. The first channel 31 and the second channel 32 are connected to each other. The second channel 32 and the first channel 31 between two adjacent main water channels 3 are connected through the branch water channel 4. Any main water channel 3 is connected with a water inlet 8 and a water outlet 9.

[0021] Specifically, the branch water channel 4 can increase the coverage area of the cooling water channel on the mold core 1 and improve the cooling effect. The cooling water enters from the water inlet 8, passes through the first channel 31 and the second channel 32 of the main water channel 3 in turn, and then flows through the branch water channel 4 to enter the next main water channel 3 for circulating cooling, and finally the cold water is discharged through the water outlet 9.

[0022] In the above embodiment, preferably, a first guide port 5 is provided at the end of the isolation plate 22 away from the column 21, and the first channel 31 and the second channel 32 are connected via the first guide port 5. Specifically, the main water channel 3 is divided into two interconnected first and second channels 31 and 32, primarily to allow the cooling water to turn around from the first channel 31 and enter the second channel 32 through the first guide port 5 in the direction of the arrow in the figure, thereby increasing the heat dissipation path of the cooling water and improving the heat dissipation effect.

[0023] In the above embodiment, preferably, the partition portion 23 is a protrusion 231 fixed to one end of the isolation plate 22, as shown in the attached Figure 2 As shown, the protrusion 231 separates the horizontal single-hole water channel into multiple main water channels 3 that are not connected to each other, so that the cooling water can only flow in the direction of the attached water channel. Figure 1 The direction of the middle arrow passes through the first channel 31, the second channel 32 and the branch water channel 4 in sequence, and then enters the next main water channel 3 for circulating cooling.

[0024] In the above embodiment, preferably, a baffle 6 placed in the main water channel 3 is fixed at one end of the branch water channel 4, and a second guide port 7 is provided at one end of the baffle 6. The second channel 32 is connected to the branch water channel 4 through the second guide port 7 on the baffle 6. Figure 1 It can be seen that the first guide port 5 and the second guide port 7 are respectively located at the two ends of the main water channel 3. The cooling water first passes through the first channel 31 and then turns around through the first guide hole on the isolation plate 22 to flow through the second channel 32. The cooling water in the second channel 32 passes through the second guide port 7 on the baffle 6 and then turns around again to enter the branch water channel 4, thereby increasing the heat dissipation path of the cooling water through the baffle 6.

[0025] In the above embodiment, preferably, the first guide port 5 and the second guide port 7 are both elliptical holes or arc-shaped notches, so that the coolant flows in one direction, making it more uniform and having higher cooling efficiency.

[0026] In the above embodiment, preferably, the main water channel 3 is an X-shaped water channel. Specifically, the number of the main water channels 3 can be increased according to actual conditions.

[0027] Example 2:

[0028] Please see the attached Figure 3 and attached Figure 4 As shown, the water-blocking assembly 2 in the mold core 1 of the present embodiment is different from the first embodiment in that:

[0029] The partition part 23 is a short plate 232 fixed on the column 21. The short plate 232 is spaced apart from the isolation plate 22. The short plate 232 divides the horizontal single-hole water channel into multiple main water channels 3 that are not connected to each other, so that the cooling water can only flow in the direction of the attached water channel. Figure 3The direction of the middle arrow passes through the first channel 31, the second channel 32 and the branch water channel 4 in sequence, and then enters the next main water channel 3 for circulating cooling.

[0030] In this embodiment, the difference from the first embodiment is that both ends of the branch water channel 4 are fixed with baffles 6 placed in the main water channel 3, one end of the baffle 6 is provided with a second guide port 7, and the second channel 32 and the first channel 31 between the two adjacent main water channels 3 are connected to the branch water channel 4 through the second guide port 7 and form a triangular flow water channel with the branch water channel 4. The triangular water channel can expand the heat dissipation area and cover the area not covered by the main water channel for heat dissipation, as shown in the attached figure. Figure 3 As shown, the baffles 6 on both sides of the main water channel 3 allow the cooling water to flow in any main water channel 3 in a one-way manner with multiple U-turns, thereby further increasing the heat dissipation path of the cooling water, expanding the heat dissipation area, and improving the heat dissipation effect. The overall structure of the horizontal single-hole water channel is simple and evenly distributed, and will not affect the distribution of the main structure inside the mold.

[0031] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
