Description

Technical Field

[0001] This utility model relates to the field of mold technology, and more specifically to a 3D printed mold with conformal cooling water channels. Background Technology

[0002] 3D printing is typically achieved using digital material printers. It is commonly used in mold making and industrial design to create models, and is increasingly being applied to the direct manufacturing of some products. 3D printed molds are a method of manufacturing molds using 3D printing technology, offering advantages such as speed, flexibility, and cost-effectiveness, and are gradually changing the landscape of the traditional mold manufacturing industry.

[0003] As shown in the prior art published in CN217622033U, although this prior art uses 3D printing technology to integrally form the injection mold with the first and second cold water pipes located within the injection mold, and can make the first and second cold water pipes as close as possible to the cavity surface without affecting the normal use of the injection mold, and can set the first and second cold water pipes to be curved to adapt to the contour of the cavity surface to achieve the best cooling effect, this prior art does not have the effect of pre-filtering the water in the cold water pipes. This causes impurities in the water to adhere to the inside of the cold water pipe walls, and the accumulation of impurities will affect the heat absorption and cooling effect of the water. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides a 3D printed mold with a conformal cooling water channel. Impurities in the cooling water are filtered through two filters between the mounting pipe and the fixing pipe, preventing impurities from being transported into the condensation channel through the water inlet pipe. This avoids impurities adhering to the inside of the condensation channel and prevents excessive accumulation of impurities from affecting the heat absorption efficiency and cooling effect of the cooling water on the workpiece, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a 3D printed mold with conformal cooling water channels, comprising a mold component, wherein the bottom of the mold component is provided with a filter assembly for filtering impurities in the cooling water;

[0006] The filter assembly includes an installation tube and a fixing tube. A connecting ring is installed on the side of the installation tube near the fixing tube, and a connecting groove is opened on the outside of the end of the fixing tube near the installation tube. The end of the connecting ring away from the installation tube is threaded to the outside of the connecting groove.

[0007] The mounting tube and the fixing tube are provided with the same mounting ring, and both ends of the mounting ring are threaded with filter screens.

[0008] Both the mounting pipe and the fixing pipe are fixedly connected to a connecting pipe on the side that is far apart from each other.

[0009] In a preferred embodiment, the top of the mold component has a mold groove, the interior of the mold component has a condensation channel corresponding to the mold groove, and the bottom of both ends of the condensation channel are respectively provided with a water inlet and a water outlet opened at the bottom of the mold component.

[0010] In a preferred embodiment, a water inlet pipe is installed on the side of the bottom of the mold component corresponding to the water inlet, and a water outlet pipe is installed on the side of the mold component corresponding to the water outlet; the connecting pipe on the mounting pipe extends into the inside of the water inlet pipe, and a positioning ring is installed at the end of the mounting pipe near the water inlet pipe, the positioning ring is sleeved on the outside of the water inlet pipe, and the inner wall of the positioning ring is threaded to the outside of the water inlet pipe.

[0011] In a preferred embodiment, a fixing ring is installed on the side of the fixing pipe away from the mounting pipe, and a branch pipe is threaded inside the fixing ring. The branch pipe is sleeved on the outside of the connecting pipe located on the fixing pipe.

[0012] In a preferred embodiment, a plurality of spaced-apart first anti-slip strips are installed on the outside of the mounting tube.

[0013] In a preferred embodiment, a plurality of spaced-apart second anti-slip strips are installed on the outside of the fixing tube.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. Impurities in the cooling water are filtered through two filter screens between the installation pipe and the fixed pipe to prevent impurities from being transported into the condensation channel through the water inlet pipe. This prevents impurities from adhering to the inside of the condensation channel and avoids excessive accumulation of impurities, which would affect the heat absorption efficiency and cooling effect of the cooling water on the workpiece.

[0016] 2. By rotating the positioning ring and fixing ring that are threaded to the inlet pipe and branch pipe, the installation pipe and fixing pipe can be removed. Since the installation pipe and fixing pipe are connected by the connecting ring and connecting groove, the installation pipe and fixing pipe can be rotated to separate them, and the two filter screens that are threaded to the installation ring can be removed, thus achieving the effect of convenient maintenance of the filter screen.

[0017] 3. By 3D printing the condensation channel, the condensation channel can fit the mold cavity more closely, thereby enabling more effective cooling and heat dissipation of the workpiece. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Refer to the instruction manual appendix Figure 1-5 This utility model provides a 3D printed mold with a conformal cooling water channel, including a mold part 1, wherein the bottom of the mold part 1 is provided with a filter component for filtering impurities in the cooling water;

[0026] like Figure 2-5 As shown, the filter assembly includes an installation tube 2 and a fixing tube 3. A connecting ring 4 is installed on the side of the installation tube 2 near the fixing tube 3, and a connecting groove 5 is opened on the outside of the end of the fixing tube 3 near the installation tube 2. The end of the connecting ring 4 away from the installation tube 2 is threaded to the outside of the connecting groove 5. The same installation ring 6 is provided inside the installation tube 2 and the fixing tube 3. Filter screens 7 are threaded to both ends of the installation ring 6. A connecting tube 8 is fixedly connected to the side of the installation tube 2 and the fixing tube 3 that is away from each other.

[0027] like Figure 1 , 2As shown in Figure 4, the top of the mold component 1 is provided with a mold groove 9, and the interior of the mold component 1 is machined with a condensation channel 10 corresponding to the mold groove 9. The bottom ends of the condensation channel 10 are respectively provided with a water inlet 11 and a water outlet 12 located at the bottom of the mold component 1. The workpiece in the mold groove 9 is cooled through the condensation channel 10. The water inlet 11 and water outlet 12 ensure the flow of cooling water. A water inlet pipe 13 is installed on the side of the bottom of the mold component 1 corresponding to the water inlet 11, and a water outlet pipe 13 is installed on the side of the bottom of the mold component 1 corresponding to the water outlet 12. An outlet pipe 14 is installed; the connecting pipe 8 on the installation pipe 2 extends into the inlet pipe 13, and a positioning ring 15 is installed at one end of the installation pipe 2 near the inlet pipe 13. The positioning ring 15 is sleeved on the outside of the inlet pipe 13, and the inner wall of the positioning ring 15 is threaded to the outside of the inlet pipe 13. The threaded connection between the positioning ring 15 and the inlet pipe 13 can enhance the stability and tightness of the connection between the installation pipe 2 and the inlet pipe 13, prevent loosening, and also facilitate the disassembly of the installation pipe 2 by the staff.

[0028] like Figure 3 and 5 As shown, a fixing ring 16 is installed on the side of the fixed pipe 3 away from the mounting pipe 2. A branch pipe 17 is threaded inside the fixing ring 16. The branch pipe 17 is sleeved on the outside of the connecting pipe 8 located on the fixed pipe 3. Through the nested connection between the branch pipe 17 and the connecting pipe 8, cooling water can be transported to the mounting pipe 2 and the interior of the fixed pipe 3 via the branch pipe 17.

[0029] like Figure 3 As shown, the installation tube 2 is equipped with multiple spaced first anti-slip strips 18 on its exterior. The multiple first anti-slip strips 18 can enhance the friction between the worker's hand and the installation tube 2, thereby ensuring the stability of the worker's operation of the installation tube 2. The fixing tube 3 is equipped with multiple spaced second anti-slip strips 19 on its exterior. The connection between the second anti-slip strips 19 and the fixing tube 3 can enhance the stability of the worker's operation of the fixing tube 3 and prevent loosening.

[0030] Workers deliver cooling water to the installation pipe 2 and the fixed pipe 3 through the branch pipe 17, and use two filters 7 in the installation ring 6 to block impurities in the cooling water, preventing impurities in the cooling water from being delivered to the condenser channel 10 through the water inlet pipe 13. This can prevent impurities from adhering to the inside of the condenser channel 10, and prevent excessive accumulation of impurities from affecting the heat absorption efficiency and cooling effect of the cooling water on the workpiece.

[0031] After filtration, the cooling water is transported to the condenser channel 10 through the inlet pipe 13. The condenser channel 10 is made by 3D printing, which allows the condenser channel 10 to fit the mold groove 9 more closely, thereby enabling more effective cooling of the workpiece. The cooling water after absorbing heat is discharged through the outlet pipe 14, thus achieving the cooling effect on the workpiece.

[0032] After prolonged use, the operator can rotate the positioning ring 15 and the fixing ring 16, which are threadedly connected to the inlet pipe 13 and the branch pipe 17, to remove the installation pipe 2 and the fixing pipe 3. Since the installation pipe 2 and the fixing pipe 3 are connected by the connecting ring 4 and the connecting groove 5, the operator can rotate the installation pipe 2 to separate it from the fixing pipe 3 and remove the two filter screens 7, which are threadedly connected to the installation ring 6, thus facilitating the cleaning and maintenance of the filter screens 7.

[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
