Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a slider core cooling structure and mold. Background Technology

[0002] like Figure 1 As shown, some injection molded products have a similar shell-pulling structure, mainly including a shell 29 and several thin-walled cavities 30 formed on the shell 29. In the actual production process, in addition to the mold cavity needing to form the outer surface of the shell 29, the thin-walled cavities 30 on the shell 29 also need to be formed by the core-pulling structure.

[0003] During the demolding process, the core-pulling structure needs to be removed from the product's cavity 30 first. However, because the slider core on the core-pulling structure reaches excessively high temperatures, and the product's cavity 30 is a thin-walled structure, directly removing the core can easily lead to product deformation and a decrease in yield. Waiting for the product and core to cool before removal would significantly reduce production efficiency, thus requiring further improvement. Utility Model Content

[0004] The primary objective of this invention is to provide a slider core cooling structure that accelerates the cooling of the slider core after product injection molding, enabling the slider core to be demolded quickly, thereby improving demolding efficiency and ensuring product quality.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A slider core cooling structure includes a slider seat slidably disposed on a moving template and a plurality of slider cores disposed on one side of the slider seat. Each slider core is provided with a cooling water channel. The plurality of cooling water channels are connected end to end in series to form a circulating water channel. The connecting water channel is disposed in the slider seat. Both ends of the circulating water channel extend to the side wall of the slider seat to form an inlet and an outlet for connecting to an external water source, respectively.

[0007] By employing the above-described scheme, the cooling speed of each slider core can be accelerated through the series-connected cooling water channels. During the process of the slider core being extracted from the product's inner cavity, this accelerates the product's cooling and solidification, thereby improving core extraction efficiency, preventing product damage, and ultimately ensuring a high product yield.

[0008] Preferably, the cooling water channel is U-shaped, with its plane parallel to the surface of the slider core and arranged along the length of the slider core.

[0009] By adopting the above solution, the cooling water channel can be evenly covered inside the slider core, thereby effectively improving cooling performance and efficiency.

[0010] Preferably, the working surface of the moving template is provided with a sliding groove for the sliding seat to slide and connect. The two opposite side walls inside the sliding groove are provided with sliding slots along their own length direction. The two sides of the sliding seat are provided with sliders that are respectively slidably engaged in the two sliding slots.

[0011] By adopting the above solution, the cooperation between the slider and the sliding slot can not only improve the stability and smoothness of the sliding seat during movement, but also prevent the sliding seat from detaching from the moving template.

[0012] Preferably, the working surface of the moving template is provided with a guide rail along the sliding direction of the sliding seat, and the bottom of the sliding seat is provided with a guide groove that slides and engages with the guide rail.

[0013] By adopting the above solution, the cooperation between the guide rail and the guide groove can effectively improve the stability and smoothness of the sliding seat's movement within the groove, further enhancing the sliding seat's accuracy and efficiency.

[0014] Preferably, the bottom of the guide groove is provided with a number of oil storage holes for storing grease along its length. A ball is rolled in the oil storage hole. A first oil outlet interval is maintained between the ball and the inner wall of the oil storage hole. An elastic element is provided between the end of the oil storage hole away from the guide rail and the ball to drive the ball to abut against the guide rail. An anti-detachment ring is provided around the end of the oil storage hole near the guide rail to prevent the ball from detaching from the oil storage hole. A second oil outlet interval is maintained between the anti-detachment ring and the ball, which is connected to the first oil outlet interval.

[0015] Using the above scheme, when the guide rail and guide groove move relative to each other, the balls can roll under the drive of the guide rail, so that the grease in the oil reservoir is sequentially coated onto the surface of the guide rail through the first and second oil outlet intervals, thereby completing the automatic lubrication of the guide rail. This makes the fit between the guide rail and the guide groove smoother and eliminates the trouble of frequently adding grease. The cooperation between the elastic element and the anti-slip ring allows the first and second oil outlet intervals to maintain a dynamic balance. When the balls wear, the elastic element can further push the balls so that the balls always remain in contact with the guide rail surface, thereby keeping the first and second oil outlet intervals within a preset range, preventing grease blockage or excessive consumption, and further improving lubrication performance.

[0016] Preferably, an anti-disengagement component is provided on the inner wall of the oil reservoir at a position away from the guide rail. The elastic component is a compression spring, with both ends of the compression spring pressing against the opposite surfaces of the anti-disengagement component and the ball bearing, respectively.

[0017] Using the above solution, the compression spring has a simple structure, is easy to install, and has low cost. Its end can be fitted into the spherical surface of the ball to provide stable and durable elastic support for the ball. The anti-disengagement component provides a fulcrum for the elastic element and prevents the elastic element and the ball from disengaging from the oil reservoir.

[0018] Preferably, the sliding seat has an oil filling groove for filling grease. The oil filling groove is located on the side of the oil reservoir hole away from the guide rail and is arranged along the direction of the arrangement of the oil reservoir holes. The oil reservoir holes are all connected to the oil filling groove, and threaded plugs are provided at both ends of the oil filling groove.

[0019] Using the above method, when the grease in the oil reservoir is depleted, the operator can add grease to the oil reservoir through the oil filling groove to extend the service life of the lubrication mechanism.

[0020] Preferably, a limiting block is provided at the bottom of the slide groove on the side away from the slider core to prevent the sliding seat from dislodging from the slide groove.

[0021] Using the above solution, the limiting block has a blocking function, which can effectively prevent the sliding seat from dislodging from the slide groove, thereby improving the connection stability between the slider core and the moving template.

[0022] Preferably, a drive mechanism for driving the sliding seat to slide is provided on the side of the sliding seat away from the slider core.

[0023] The above solution enables the sliding seat and slider core to operate efficiently on the moving template.

[0024] The second objective of this invention is to provide a mold that can accelerate the cooling of the slider core during product demolding, thereby improving demolding efficiency and ensuring product yield.

[0025] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0026] A mold with a slider core cooling structure includes a fixed template that cooperates with a moving template. The working surface of the moving template is provided with a cavity for molding products. A sliding seat is located on one side of the cavity, and the slider core is located on the side of the sliding seat near the cavity.

[0027] Using the above solution, during injection molding, the slider core can be pushed into the cavity to shape the outer surface and thin-walled recesses of the product. During demolding, the cooling structure accelerates the cooling of the slider core, allowing it to be withdrawn from the product's cavity more quickly and reducing the probability of product damage. This improves both production efficiency and yield.

[0028] This utility model, by adopting the above technical solution, has significant technical effects:

[0029] 1. The series-connected cooling water circuits can accelerate the cooling speed of each slider core. During the process of the slider core being pulled out of the product cavity, this accelerates the cooling and solidification of the product, thereby improving core-pulling efficiency, preventing product damage, and ensuring a high product yield.

[0030] 2. During injection molding, the slider core is pushed into the mold cavity to shape the outer surface and thin-walled recesses of the product. When the product is demolded, the cooling structure accelerates the cooling of the slider core, allowing it to be withdrawn from the product's cavity more quickly and reducing the probability of product damage. This improves both production efficiency and yield. Attached Figure Description

[0042] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Example 1

[0043] like Figures 2 to 10 As shown, this embodiment discloses a slider core cooling structure, including a sliding seat 1 slidably disposed on the working surface of the moving template 28 and a plurality of slider cores 2 fixedly disposed on one side of the sliding seat 1. The number of slider cores 2 can be determined according to the number of thin-walled cavities 30 in the injection molded product, and is not limited here. The slider core 2 has a long strip-shaped plate structure, and each slider core 2 is provided with a cooling water channel 3. The cooling water channel 3 is U-shaped, and its plane is parallel to the plate surface of the slider core 2 and is arranged along the length direction of the slider core 2. The plurality of cooling water channels 3 are connected end to end by connecting water channels 4 to form a complete circulating water channel 5. The connecting water channels 4 are disposed inside the sliding seat 1, and both ends of the circulating water channel 5 extend to the side wall of the sliding seat 1 to form an inlet 7 and an outlet 8 for connecting an external water source, respectively. The water source includes a water tank (not shown) and a water pump (not shown). After the water pump is started, it can transfer the cooling water in the water tank to the circulating water path 5 through the water inlet 7, and then circulate it back to the water tank through the water outlet 8 to accelerate the cooling of the slider core 2.

[0044] To prevent the sliding seat 1 from detaching from the moving template 28, the working surface of the moving template 28 is provided with a sliding groove 9 for the sliding seat 1 to slide and connect. The two opposite side walls of the sliding groove 9 are provided with sliding slots 10 along their own length direction. The two sides of the sliding seat 1 are provided with sliders 11 that are respectively slidably engaged in the two sliding slots 10.

[0045] In order to improve the stability and smoothness of the sliding seat 1 during operation, the working surface of the moving template 28 is fixedly provided with a guide rail 12 along the sliding direction of the sliding seat 1, and the bottom of the sliding seat 1 is provided with a guide groove 13 that slides and cooperates with the guide rail 12.

[0046] To improve the lubrication between the guide rail 12 and the guide groove 13, the bottom of the guide groove 13 is provided with several oil storage holes 14 along its length for storing grease. A ball bearing 15 is rolled within the oil storage hole 14 near the guide rail 12. A first oil outlet interval 16 is maintained between the ball bearing 15 and the inner wall of the oil storage hole 14. An elastic element 17 is provided between the end of the oil storage hole 14 away from the guide rail 12 and the ball bearing 15 to drive the ball bearing 15 to abut against the guide rail 12. An anti-detachment element 20 is provided on the inner wall of the oil storage hole 14 at a position away from the guide rail 12. The elastic element 17 is a compression spring, with its two ends pressing against the anti-detachment element 20 and the opposing surfaces of the ball bearing 15, respectively. An anti-detachment ring 18 is provided around the oil storage hole 14 near the guide rail 12 to prevent the ball bearing 15 from detaching from the oil storage hole 14. The inner curvature of the anti-detachment ring 18 is adapted to the spherical surface of the ball bearing 15. The anti-detachment ring 18 and the ball 15 are connected by a second oil outlet interval 19 connected to the first oil outlet interval 16, so that the grease in the oil reservoir 14 can be smoothly carried out by the ball 15 to the surface of the guide rail 12.

[0047] To facilitate the addition of grease to the oil reservoir, the sliding seat 1 is provided with an oil filling groove 21 for filling grease. The oil filling groove 21 is located on the side of the oil reservoir 14 away from the guide rail 12 and is arranged along the direction of the arrangement of the oil reservoir 14. All the oil reservoir 14 are connected to the oil filling groove 21. Threaded plugs 22 are provided at both ends of the oil filling groove 21. The outer end face of each threaded plug 22 is provided with a cross groove 25 to facilitate the installation and removal of the threaded plug 22 by the operator using a cross screwdriver.

[0048] To prevent the sliding seat 1 from detaching from the slide groove 9, a limiting block 23 is fixedly provided at the bottom of the slide groove 9 on the side away from the slider core 2 to prevent the sliding seat 1 from detaching from the slide groove 9. A drive mechanism for driving the sliding seat 1 to slide is provided on the side of the sliding seat 1 away from the slider core 2. In this embodiment, the drive mechanism includes a drive rod 26 fixed to the rear side of the sliding seat 1 and an output shaft (not shown) fixed to the mounting hole 31 of the drive rod 26 to drive the drive rod 26 and the sliding seat 1 to move forward and backward. The hydraulic cylinder is mounted on the moving template 28. Its specific structure and installation method are common knowledge in the art and do not involve the improvement of this solution, so they will not be described in detail. Example 2

[0049] Based on Embodiment 1, this embodiment discloses a mold including the above-mentioned slider core cooling structure, including a fixed template (not shown) that cooperates with the moving template 28. The working surface of the moving template 28 is provided with a cavity 24 for molding the product. The sliding seat 1 is located on one side of the cavity 24, and the slider core 2 is located on the side of the sliding seat 1 close to the cavity 24, so as to facilitate the slider core 2 to mold the concave cavity 30 in the product.

[0050] The principle of the slider core cooling structure and mold is now explained in conjunction with Embodiment 1 and Embodiment 2:

[0051] During injection molding, with the mold open, the sliding seat 1 is pushed towards the cavity 24 on the moving platen 28 by the drive mechanism, causing the slider core 2 to enter the cavity 24. Then, the mold closes. The injection head (not shown), which is connected to the fixed platen (not shown), injects molten plastic into the cavity 24 to shape the outer surface of the product, while simultaneously shaping the recess 30 of the product through the slider core 2. After injection molding is completed, the water pump is started to run the circulating water circuit 5, thereby rapidly cooling the slider core 2. When the temperature drops to the specified temperature, the mold can be opened, and the slider core 2 is pulled out of the recess 30 of the product. The product is then demolded through the ejector mechanism (not shown), thus completing the product production.

[0052] During operation, the elastic element 17 can drive the ball 15 in the oil storage hole 14 to abut against the surface of the guide rail 12 and roll under the friction of the guide rail 12, so as to carry the grease in the oil storage hole 14 through the first oil outlet interval 16 and the second oil outlet interval 19 to the surface of the guide rail 12, thereby lubricating the guide rail 12 and improving the lubrication between the guide rail 12 and the guide groove 13, making the operation of the sliding seat 1 more stable and smooth.

[0053] Once the grease in the oil reservoir 14 is depleted, remove the threaded plug 22 using a screwdriver (not shown). Then, inject grease into the oil filling channel using a grease gun (not shown) to fill the oil reservoir 14 with grease. After filling, reinstall the threaded plug 22.
