[0039] The patterns formed by corrosion on the mold surface are mainly due to corrosion phenomena caused by the influence of gas, molten metal, and chemicals on the mold during the die casting process. These corrosion phenomena include mold cavitation, erosion, and chemical corrosion, which cause different damages to the mold surface and form specific patterns, that is, create the uneven molding surface of the mold.
[0040] Chemical corrosion is a phenomenon where the chemical reaction between molten metal and the mold surface material leads to corrosion and damage to the mold surface. Chemical corrosion typically manifests as discoloration, pitting, and a decline in surface quality. It is primarily caused by the interaction between the molten metal and the mold material. However, when applying liquids that chemically react with the mold material to the mold surface, there is a lack of easy-to-use and clean brushes.
[0041] Based on the above-mentioned problems, in this embodiment, the assembled soft liquid reservoir, grip tube, and pen tip can be used to paint on the mold surface by squeezing the liquid reservoir, thereby creating the mold's uneven molding surface. The detachable liquid reservoir, grip tube, and pen tip facilitate the drawing of liquid into the correction pen and allow for cleaning of the interior and connections of these components when not in use, maintaining the cleanliness of the correction pen's interior. The detachable pen tip allows for easy replacement of different diameter dispensing holes to draw line segments of varying widths.
[0042] Figure 1 The diagram shows the overall structure of the mold pattern etching brush in this embodiment of the present disclosure. Figure 2 The following is an embodiment of this disclosure. Figure 1 A sectional view. In Figure 1 and Figure 2 In the example, the mold pattern etching pen includes a liquid reservoir 10 and a pen tip 30. The liquid reservoir 11 is configured to store corrosive liquid and is squeezeable. The pen tip 30 is detachably mounted to the liquid reservoir 10 to communicate with the liquid reservoir 11; the tip of the pen tip 30 forms an outlet hole 301 for corrosive liquid squeezed out from the liquid reservoir 11 to flow out.
[0043] For example, the detachable connection between the pen tip 30 and the liquid reservoir 10 allows the user to easily replace the pen tip 30 with different diameter liquid outlet holes 301 to draw line segments of different line widths.
[0044] The advantage of the above arrangement is that the combined soft liquid storage member 10 and the pen head 30 can be used to draw on the mold surface by squeezing the liquid storage member 10 to form the mold concave-convex forming surface. The detachable liquid storage member 10 and the pen head 30 can facilitate the absorption of liquid into the brush, and can clean the inside of the liquid storage member 10 and the pen head 30 and the connection part when not in use, keeping the inside of the brush clean. The detachable pen head 30 can facilitate the replacement of pen heads 30 with different liquid outlet hole 301 diameters to draw lines of different widths.
[0045] For example, the liquid storage member 10 includes a liquid storage bag 11 and a communication part 12 communicating with the opening of the liquid storage bag 11. The liquid storage bag 11 has a liquid storage cavity 1101. For example, the liquid storage bag 11 is made of soft material such as rubber or plastic, so that the user can squeeze the liquid storage bag 11 to make the liquid in the liquid storage cavity 1101 overflow from the liquid outlet hole 301 to the mold surface due to the increase of the internal pressure of the liquid storage cavity 1101. For example, the communication part 12 is made of hard material. It can be understood that the hard communication part 12 can facilitate the connection and communication with the pen head 30.
[0046] For example, the installation mode of the liquid storage member 10 and the pen head 30 is implemented by screwing. Further, the communication part 12 of the liquid storage member 10 is screwed into the interface 32 of the pen head 30. Those skilled in the art can understand that when the mold pattern etching brush is held, the liquid storage member 10 and the pen head 30 are arranged from top to bottom in sequence. Therefore, the above arrangement has the advantage that the gap between the liquid storage member 10 and the pen head 30 and the liquid access point are downward, so that the possibility of liquid leakage from the gap between the liquid storage member 10 and the pen head 30 is greatly reduced due to gravity, thereby further improving the sealing effect of the connection between the liquid storage member 10 and the pen head 30.
[0047] Further, a sealing member (not shown in the figure) such as a raw material belt or a rubber ring is arranged between the communication part 12 and the interface of the pen head 32.
[0048] Figure 3 The cross-sectional view of the holding tube in the embodiment of the present disclosure is shown in FIG. 1B. Figure 4 The cross-sectional view of the holding tube in the embodiment of the present disclosure is shown in FIG. 1B. Figure 3 The enlarged view of A in FIG. 1C. In Figure 3 and Figure 4In an example, the mold pattern etching pen further comprises a holding tube 20. The holding tube 20 is detachably mounted between the liquid storage member 10 and the pen head 30 to connect the liquid storage member 10 and the pen head 20. A first port 201 of the holding tube 20 is detachably mounted to the connecting portion 12; and an interface 32 of the pen head 30 is detachably mounted to a second port 202 of the holding tube 20.
[0049] In an example, the holding tube 20 comprises a flow guide cavity 203 for connecting the first port 201 and the second port 202. The wall surface of the liquid storage cavity 1101 and the wall surface of the flow guide cavity 203 are respectively provided with an oil-repellent layer (not shown in the figure). As understood by those skilled in the art, the oil-repellent layer reduces the interfacial tension, so that there is a layer of separation barrier between the two interacting substances, thereby preventing the liquid from adhering and diffusing on the wall surface of the liquid storage cavity 1101 and the wall surface of the flow guide cavity 203, and protecting the wall surface of the liquid storage cavity 1101 and the wall surface of the flow guide cavity 203 from being contaminated. In addition, the oil-repellent layer also has the effects of antibacterial and antioxidant, which can prolong the service life of the liquid storage bag 11 and the holding tube 20.
[0050] In an example, the outer wall of the holding tube 20 is configured as a holding portion. In a further example, the surface of the holding portion is provided with an anti-slip layer (not shown in the figure). For example, the anti-slip layer is implemented as an abrasive layer. In this way, the provision of the anti-slip layer can increase the friction between the user's hand and the holding tube 20, and avoid the mold pattern etching pen from falling off the user's hand.
[0051] In an example, the mounting manner of the liquid storage member 10 and the holding tube 20 and the mounting manner of the holding tube 20 and the pen head 30 are both implemented as screwing or plugging. In the present embodiment, the screwing manner is adopted, i.e., one of the liquid storage member 10 and the holding tube 20 forms an internal thread, and the other forms an external thread matched with the internal thread; and one of the holding tube 20 and the pen head 30 forms an internal thread, and the other forms an external thread matched with the internal thread. The advantage of this arrangement is that the implementation of the internal thread and the external thread can further improve the sealing contact surface between the liquid storage member 10 and the holding tube 20, and between the holding tube 20 and the pen head 30, and further improve the sealing performance of the mold pattern etching pen.
[0052] In another embodiment, the mounting manner of the liquid storage member 10 and the holding tube 20 and the mounting connection manner of the holding tube 20 and the pen head 30 are both implemented as plugging.
[0053] Further exemplary, the connecting part 12 of the liquid storage member 10 is inserted into the first port 201 of the holding tube 20; the second port 202 of the holding tube 20 is inserted into the interface 32 of the pen head 30. Those skilled in the art can understand that, when the mold pattern etching pen is held, the liquid storage member 10, the holding tube 20 and the pen head 30 are sequentially arranged from top to bottom. Therefore, the gap between the liquid storage member 10 and the holding tube 20 and the point of contact of the liquid are downwardly arranged, so that the possibility of leakage of the liquid from the gap between the liquid storage member 10 and the holding tube 20 is greatly reduced due to the effect of gravity, thereby further improving the sealing effect of the connection between the liquid storage member 10 and the holding tube 20. The effect of the connection between the holding tube 20 and the pen head 30 is the same as that of the connection between the liquid storage member 10 and the holding tube 20, and therefore is not described here.
[0054] Exemplarily, the connection between the liquid storage member 10 and the holding tube 20 and the connection between the holding tube 20 and the pen head 30 are provided with sealing members (not shown in the figure). Further exemplary, the sealing members are implemented as raw material belts or sealing rings. For example, the raw material belts are wound around the external threads formed in the liquid storage member 10, the holding tube 20 and the pen head 30. It can be understood that, the sealing members can improve the sealing effect of the connection between the liquid storage member 10 and the holding tube 20 and the connection between the holding tube 20 and the pen head 30, thereby avoiding leakage of the liquid.
[0055] In Figure 3 and Figure 4 Exemplarily, the connecting part 12 of the liquid storage member 10 is inserted into the first port 201 of the holding tube 20; the end surface of the second port 202 is provided with an annular sealing groove 204 parallel to the extending direction of the second port 202, and the interface 32 of the pen head 30 is screwed into the annular sealing groove 204. Further exemplary, at least one of the bottom wall of the annular sealing groove 204 and the end surface of the interface 32 is provided with a sealing ring 40 to form a seal when the end surface of the interface 32 of the pen head 30 abuts against the bottom wall of the annular sealing groove 204. In this embodiment, the sealing ring 40 is arranged on the end surface of the interface 32. In another embodiment, the sealing ring 40 is arranged on the bottom wall of the annular sealing groove 204, or both the bottom wall of the annular sealing groove 204 and the end surface of the interface 32 are provided with the sealing ring 40. Those skilled in the art can understand that, by arranging the sealing ring 40 on both the bottom wall of the annular sealing groove 204 and the end surface of the interface 32, the sealing performance between the pen head 30 and the holding tube 20 can be further improved.
[0056] Figure 5 Another embodiment of the connection between the pen head and the holding tube is shown in the cross-sectional view of the interface between the pen head and the holding tube. Figure 5In an example, the end face of the second port 202 is provided with an annular sealing groove 204 parallel to the extension direction thereof, and the interface 32 of the pen head 30 is screwed into the annular sealing groove 204. In a further example, the two annular walls of the annular sealing groove 204 form inner threads with the same hand and the same starting angle, and the inner and outer walls of the interface 32 of the pen head 30 form outer threads with the same hand, the same starting angle and screwed with the inner threads. It can be understood by those skilled in the art that the implementation of double-layer threads can further improve the contact surface between the holding tube 20 and the pen head 30 to form a seal, thereby further improving the sealing performance of the mold pattern etching pen. Figure 4 In an example, the sealing ring 40 is provided in the same way as Figure 3 In an example, the sealing ring 40 is provided in the same way as
[0057] Figure 6 FIG. 1 shows the overall structure of a mold pattern etching pen with a cap according to an embodiment of the present disclosure. In Figure 3 , Figure 4 and Figure 6 In an example, the mold pattern etching pen further comprises a cap 50. The cap 50 is detachably sleeved on the second port 202 of the holding tube 20 to cover the pen head 30. In an example, the cap 50 and the holding tube 20 are detachable in the form of plug-in. It can be understood that, after the cap 50 is sleeved on the holding tube 20, the pen head 30 can be prevented from being damaged due to contact with other objects. In a further example, the cap 50 is made of hard material.
[0058] In summary, the mold pattern etching pen according to an embodiment of the present disclosure comprises a liquid storage member, a holding tube and a pen head. The liquid storage member comprises a liquid storage bag and a communication part communicating with the opening of the liquid storage bag. The first port of the holding tube is detachably connected to the communication part; the pen head is detachably connected to the second port of the holding tube; and the end of the pen head away from the holding tube is provided with a liquid outlet hole for the liquid storage bag to communicate with the outside. When the liquid storage bag is squeezed, the liquid inside the liquid storage bag flows out through the liquid outlet hole. The above arrangement has the advantage that the soft liquid storage member and the pen head after combination can be squeezed to draw on the mold surface. The detachable liquid storage member and pen head can not only facilitate the absorption of liquid into the pen, but also can clean the inside of the liquid storage member and the pen head and the connection part when not in use, so as to keep the inside of the pen clean. The detachable pen head can facilitate the replacement of pen heads with different liquid outlet hole diameters to draw lines with different line widths.
[0059] The above embodiments are only illustrative of the principles of the present disclosure and its effects, and are not intended to limit the present disclosure. Any modification or change made by any person skilled in the art without departing from the spirit and scope of the present disclosure shall be covered by the protection scope of the present disclosure.
