[0035] Figure 1 Schematic diagram of the structure of the mold of the embodiment of the present disclosure. Figure 1 The mold of the embodiment of the present disclosure includes a first mold assembly 10 and a second mold assembly 20 .
[0036] Figure 2 2 is a schematic diagram of the structure of the second mold assembly 20 according to an embodiment of the present disclosure. Figure 1 and Figure 2The second mold assembly 20 includes a first sub-mold 21 and a second sub-mold 22. The first sub-mold 21 is spaced apart from and arranged opposite to the first mold assembly 10, and the first sub-mold 21 is positioned and connected with a driving part 23.
[0037] The second sub-mold 22 is disposed between the first sub-mold 21 and the first mold assembly 10, and the first sub-mold 21, the second sub-mold 22 and the first mold assembly 10 cooperate to form a moldable product 900 (see Figure 3 ) molding cavity. However, it is understandable that the product 900 that can be molded by the present disclosure includes but is not limited to this, and this is only a simple example made to facilitate those skilled in the art to understand the present disclosure.
[0038] In other words, the molding cavity of the first mold assembly 10 and the second mold assembly 20 is formed by the first mold assembly 10 and the first sub-mold 21 and the second sub-mold 22, thereby, when the material in a fluid state is filled into the molding cavity and cooled and solidified, the product 900 having a predetermined shape in the molding cavity is molded, thereby, the product 900 is molded between the first sub-mold 21, the second sub-mold 22 and the first mold assembly 10, and after molding, the first sub-mold 21, the second sub-mold 22 and the first mold assembly 10 are combined with the surface of the product 900.
[0039] When the second mold assembly 20 moves away from the first mold assembly 10, the first sub-mold 21 is separated from the second sub-mold 22 and drives the driving part 23 to move to a position combined with the second sub-mold 22, so as to drive the second sub-mold 22 to be separated from the product 900 during the moving away.
[0040] Therefore, when the second mold assembly 20 opens and moves away from the first mold assembly 10 to demold the product 900 molded in the molding cavity, the first sub-mold 21 first moves in a direction away from the first mold assembly 10, thereby, the part of the first sub-mold 21 combined with the product 900 will first separate from the product 900. At this time, the second sub-mold 22 still remains stationary and remains in a state of being combined with the product 900.
[0041] At the same time, the movement of the first sub-mold 21 will also drive the driving part 23 to move, until the driving part 23 reaches the position combined with the second sub-mold 22 and combines with the second sub-mold 22. At this point, when the first sub-mold 21 continues to move in the direction away from the first mold assembly 10, the driving part 23 will pull the second sub-mold 22 to move in the direction away from the first mold assembly 10, so that the part of the second sub-mold 22 combined with the product 900 will be separated from the product 900.
[0042] Optionally, the second sub-mold 22 includes a first mold part 221 and a second mold part 222. The second mold part 222 is disposed on a side of the first mold part 221 facing the first mold assembly 10.
[0043] The driving part 23 includes a first driving member 231 and a second driving member 232. When the second mold assembly 20 moves away from the first mold assembly 10, the first sub-mold 21 drives the first driving member 231 to move to a position combined with the first mold 221, and the first sub-mold 21 drives the second driving member 232 to move to a position combined with the second mold 222, so that the first mold 221 and the second mold 222 are separated from the product 900 one after another.
[0044] Therefore, when the second mold assembly 20 opens and moves away from the first mold assembly 10 to demold the product 900 molded in the molding cavity, the first sub-mold 21 first moves in a direction away from the first mold assembly 10, thereby, the part of the first sub-mold 21 combined with the product 900 will first separate from the product 900, and at this time, the first module 221 and the second module 222 still remain stationary and remain in a state of being combined with the product 900.
[0045] When the first sub-mold 21 drives the first driving member 231 to move to a position where it can be combined with the first module 221, the first driving member 231 pulls the first module 221 to move away from the first module assembly 10, so that the part of the first module 221 combined with the product 900 will be separated from the product 900. At this stage, the first sub-mold 21 and the first module 221 maintain synchronous movement, and the second module 222 remains stationary and remains in a state of being combined with the product 900.
[0046] When the first sub-mold 21 drives the second driving member 232 to move to a position where it can be combined with the second module 222, the second driving member 232 pulls the second module 222 to move away from the first mold assembly 10, so that the part of the second module 222 combined with the product 900 will be separated from the product 900 later. At this stage, the first sub-mold 21, the second module 222 and the first module 221 maintain synchronous movement, and the mold opening between the first mold assembly 10 and the second mold assembly 20 has been completed.
[0047] Therefore, during the demolding process of the product 900, the demolding between the second mold assembly 20 and the product 900 is completed in steps. Therefore, during the entire mold opening process, the parts of the product 900 that are in contact with the second mold assembly 20 are gradually exposed. For example, the part of the product 900 that is in contact with the first sub-mold 21 is exposed first, and the part of the product 900 that is in contact with the second sub-mold 22 is exposed later. Therefore, the demolding force (i.e., the interaction force between the second mold assembly 20 and the product 900) that the product 900 is subjected to when it is separated from the second mold assembly is small, the product 900 is easy to demold and is not easy to be damaged, thereby ensuring the quality of the product 900.
[0048] Optionally, see Figure 1 and Figure 3 , the first sub-mold 21 is arranged above the second sub-mold 22. It is worth mentioning that the gas in the molding cavity tends to float up and accumulate at the top of the product 900, for example, at the port 921 of the first barrel 92 of the product, causing air to be trapped at the port 921, resulting in surface defects such as bubbles at the port 921. The present disclosure first separates the first sub-mold 21 located at the top, i.e., combined with the top of the product 900, from the product 900, thereby avoiding the phenomenon that the product 900 has surface defects such as bubbles at the port 921 due to trapped air, and the quality of the molded product is high.
[0049] Optionally, see 1 and Figure 2 The first driving member 231 includes a first guide rod 2311 and a first pulling portion 2312. The first guide rod 2311 is positioned and connected to the first sub-mold 21 and passes through the first mold 221. The first pulling portion 2312 is provided at the passing portion of the first guide rod 2311 and extends radially outwardly therefrom, and is used to pull the first mold 221.
[0050] The second driving member 232 includes a second guide rod 2321 and a second pulling portion 2322. The second guide rod 2321 is positioned and connected to the first sub-mold 21 and passes through the second mold 222, and the length of the second guide rod 2321 is greater than that of the first guide rod 2311. The second pulling portion 2322 is provided at the passing portion of the second guide rod 2321 and extends radially outwardly therefrom, and is used to pull the second mold 222.
[0051] Specifically, in the process of the second mold assembly 20 opening the mold away from the first mold assembly 10 to demold the product 900 molded in the molding cavity, the first sub-mold 21 first drives the first pulling portion 2311 to pass through the second mold 222 and move to a position against the first mold 221, thereby, the first pulling portion 2311 will pull the first mold 221 to move away from the first mold assembly 10, so that the part of the first mold 221 combined with the product 900 will first separate from the product 900.
[0052] When the first sub-mold 21 continues to move, the first sub-mold 21 drives the second pulling portion 2321 to move to a position against the second module 222, thereby, the second pulling portion 2321 will pull the second module 222 to move away from the first mold assembly 10, so that the part of the second module 222 combined with the product 900 will be separated from the product 900.
[0053] Optionally, a countersunk hole 22201 capable of cooperating with the first pulling portion 2311 or the second pulling portion 2321 may be further provided on the surface of the first module 221 or the second module 222 facing the first module assembly 10. During the process of the first module 221 and the second module 222 being driven, the first pulling portion 2311 and the second pulling portion 2321 can be firmly retained in the countersunk hole 22201 and are unlikely to move relative to each other, thereby ensuring that the first module 221 and the second module 222 can be pulled stably and smoothly along a predetermined direction.
[0054] Figure 4 yes Figure 2 A magnified schematic diagram of part A in Figure 2. Figure 1 , Figure 2 and Figure 4 The second sub-mold 22 includes a first mold 221 and a second mold 222. The first mold 221 and the second mold 222 cooperate to form a concave hole 2201 and a first through hole 22101 located in the concave hole 2201, and the end of the first through hole 22101 is closed by the first sub-mold 21. The second mold 222 is arranged on a side of the first mold 221 facing the first mold assembly 10.
[0055] The first mold assembly 10 includes a third sub-mold 11 and an inner insert component 12. The third sub-mold 11 is arranged opposite to the second mold 222 to cooperate with the concave hole 2201 to form the chassis 91 of the product 900, and the inner insert component 12 passes through the third sub-mold 11 and the concave hole 2201 and is inserted into the first through hole 22101 with a gap, so as to form a first gap between the outer wall of the inner insert component 12 and the inner wall of the first through hole 22101 to form the first barrel 92 of the product.
[0056] Optionally, the first module 221 and the second module 222 also form a second through hole 22102 located in the recessed hole 2201, and the inner insert component 12 is also inserted into the second through hole 22102 with a gap to form a second gap between the outer wall of the inner insert component 12 and the inner wall of the second through hole 22102 that can form the second barrel 93 of the molded product.
[0057] Optionally, the second mold 222 forms a through molding gap 2202 to mold the protrusion 911 on the upper surface of the chassis of the product 900, and the first mold 221 closes the side opening of the molding gap 2202 close to the first sub-mold 21. Therefore, when the first mold 221 and the second mold 222 are separated from the product 900, the first mold 221 can be separated from the upper surface of the protrusion 911 first, and the second mold 222 can be separated from the side of the protrusion 911. During the demolding process, the interaction between the second mold assembly 20 and the product 900 is small, so that the product 900 will not move with the second mold assembly 20.
[0058] Figure 5 is a schematic diagram of the structure of the first mold assembly 10 according to an embodiment of the present disclosure. Figure 4 and Figure 5 The inner insert component 12 includes a first insert 121, a second insert 122 and a third insert 123. The first insert 121 is inserted into the concave cavity 2201 through the third sub-mold 11. The second insert 122 is arranged on the first insert 121 and inserted into the first through hole 22101 with a gap to form a first gap that can form the first barrel portion 92 of the product. The third insert 123 is arranged on the first insert 121 and inserted into the second through hole 22102 with a gap to form a second gap that can form the second barrel portion 93 of the product.
[0059] Optionally, the inner insert component 12 can be floatably disposed on the third sub-mold 11 in a direction far from or near the second mold assembly 20 .
[0060] Therefore, when the first mold assembly 10 and the second mold assembly 20 are opened, by driving the inner embedded component 12 to float, the product 900 can be moved, so that the product 900 can be demolded from the third sub-mold 11, and finally the product 900 can be pulled out from the inner embedded component 12, so as to facilitate the complete removal of the product 900.
[0061] Optionally, the first mold assembly 10 further includes a mounting seat 13, a floating seat 14, a guide connector 15 and a floating elastic member 16. The mounting seat 13 forms a floating space 1301. The floating seat 14 is arranged in a floating manner in the floating space 1301, and the inner insert component 12 is connected to the floating seat 14. One end of the guide connector 15 is connected to the third sub-mold 11, and the other end passes through the floating seat 14, and the end forms an anti-detachment portion 151 that can prevent the floating seat 14 from detaching from the guide connector 15. The floating elastic member 16 is arranged between the third sub-mold 11 and the floating seat 14. As a result, the inner insert component 12 is floatable, and after the driving force driving the inner insert component 12 to float disappears, the inner insert component 12 can automatically reset.
[0062] Optionally, the mounting seat 13 includes a mounting plate 131 and two supports 132. The two supports 132 are arranged on the mounting plate 131 at an interval to form the floating space 1301 between the two supports 132.
[0063] Figure 6 FIG. 2 is a schematic diagram of a partially exploded structure of the second mold assembly 20 of the embodiment of the present disclosure. Figure 6 , the second mold assembly 20 further includes an elastic component 24, which is disposed between the first sub-mold 21 and the second sub-mold 22. Thus, when the first sub-mold 21 is opened and away from the second sub-mold 22, the elastic component 24 can drive the first sub-mold 21 and the second sub-mold 22 to separate quickly, and when the first sub-mold 21 is closed and close to the second sub-mold 22, the elastic component 24 can play a buffering role between the first sub-mold 21 and the second sub-mold 22 to prevent the two from being damaged by collision.
[0064] Optionally, the elastic component 24 further includes a first elastic member 241. The first elastic member 241 is disposed between the first sub-mold 21 and the first mold 221. Thus, when the first sub-mold 21 is opened and away from the first mold 221, the first elastic member 241 can drive the first sub-mold 21 and the first mold 221 to separate quickly, and when the first sub-mold 21 is closed and close to the first mold 221, the first elastic member 241 can play a buffering role between the first sub-mold 21 and the first mold 221.
[0065] The elastic assembly 24 further includes a second elastic member 242. The second elastic member 242 is disposed between the second mold 222 and the first mold 221. Thus, when the first mold 221 is opened and away from the second mold 222, the second elastic member 242 can drive the first mold 221 and the second mold 222 to separate quickly, and when the first mold 221 is closed and close to the second mold 222, the second elastic member 242 can play a buffering role between the first mold 221 and the second mold 222.
