Description

Technical Field

[0001] This application relates to the field of mold technology, and in particular to a moving mold and an injection mold. Background Technology

[0002] In related technologies, some injection molds have a secondary demolding mechanism on the moving mold. The secondary demolding mechanism separates the molded product from the moving mold by pushing the molded product in two stages.

[0003] However, the secondary demolding mechanism in this technology has a complex structure, which may cause jamming during the secondary ejection process, and in severe cases, even breakage of related components. Furthermore, because the ejection stroke of this type of secondary demolding mechanism is relatively long, the thickness of the injection mold is also larger. Consequently, the injection molding machine used to install the mold also needs to be larger to meet the installation requirements, resulting in a relatively high overall cost for injection molding. Utility Model Content

[0004] In view of this, the embodiments of this application aim to provide a mold moving mold and an injection mold that have a simple structure and can reduce the thickness of the injection mold.

[0005] To achieve the above objectives, one embodiment of this application provides a moving mold, comprising:

[0006] Support plate;

[0007] A movable mold core is fixed to the support plate, and the movable mold core protrudes from a first side of the support plate along a first direction;

[0008] A secondary demolding mechanism is provided on the first side of the support plate. The secondary demolding mechanism includes a first push plate, a second push plate, and a pusher. The second push plate is located on the side of the first push plate away from the support plate along the first direction. The first push plate and the second push plate can be separated from each other and can both move along the first direction. The pusher is fixed to the first push plate and protrudes from the side of the second push plate away from the support plate along the first direction.

[0009] In this process, the first push plate and the second push plate move together to a first position in a direction away from the support plate under the action of the thrust, so that the ejector pushes the molded product retained on the moving mold core to the first ejection position under the drive of the first push plate. The second push plate separates from the first push plate at the first position and moves to a second position in a direction away from the first push plate under the action of the thrust, so as to push the molded product in the first ejection position to the demolding position.

[0010] In one embodiment, the first push plate and the second push plate are respectively sleeved on the moving mold core;

[0011] And / or, the pusher is a moving mold insert.

[0012] In one embodiment, the moving mold core has a first molding surface and a second molding surface for constructing the molded product. The first molding surface is located on the side of the moving mold core away from the support plate along the first direction, and the second molding surface is located on the outer periphery of the moving mold core. When the first push plate and the second push plate are in their initial positions, the first push plate and the second push plate are located between the support plate and the second molding surface, and on a projection plane perpendicular to the first direction, the projection of the second push plate at least partially coincides with the projection of the portion of the molded product constructed by the second molding surface.

[0013] The pusher pushes the molded product by moving in a direction protruding from the first molding surface. When the second pusher moves to the second position, the distance between the second pusher and the support plate along the first direction is greater than the distance between the second molding surface and the support plate along the first direction.

[0014] In one embodiment, the ejector is located on one side of the moving mold core along a second direction, which is perpendicular to the first direction; the ejector has a third forming surface on the side of the moving mold core away from the second direction for constructing the molded product; when the first push plate and the second push plate are in their initial positions, the first push plate and the second push plate are located between the support plate and the third forming surface, and on the projection plane, the projection of the second push plate at least partially coincides with the projection of the portion of the molded product constructed by the third forming surface.

[0015] In one embodiment, the moving mold includes a first limiting member and a second limiting member. The first limiting member has a first rod portion and a first limiting portion disposed at one end of the first rod portion. The second limiting member has a second rod portion and a second limiting portion disposed at one end of the second rod portion. The end of the first rod portion away from the first limiting portion and the end of the second rod portion away from the second limiting portion are respectively connected to the support plate. The distance between the first limiting portion and the support plate along the first direction is less than the distance between the second limiting portion and the support plate along the first direction.

[0016] When the first push plate and the second push plate move to the first position, the first limiting part abuts against the first push plate, and when the second push plate moves to the second position, the second limiting part abuts against the second push plate.

[0017] In one embodiment, the cross-sectional area of ​​the first limiting portion perpendicular to the first direction is greater than the cross-sectional area of ​​the first rod portion perpendicular to the first direction; the first push plate has a first mounting channel extending along the first direction; the second push plate has a clearance channel extending along the first direction and communicating with the first mounting channel; the cross-sectional area of ​​the clearance channel perpendicular to the first direction is greater than the cross-sectional area of ​​the first mounting channel perpendicular to the first direction; the first rod portion passes through the first mounting channel, and the clearance channel avoids the first limiting portion.

[0018] And / or, the first push plate has a second mounting channel extending along the first direction, the second push plate has a third mounting channel extending along the first direction and communicating with the second mounting channel, and the second rod portion passes through the second mounting channel and the third mounting channel.

[0019] In one embodiment, the first push plate further has a first limiting groove that communicates with the first mounting channel and the avoidance channel respectively. When the first push plate and the second push plate move to the first position, the first limiting part is located in the first limiting groove.

[0020] In one embodiment, the second push plate further has a second limiting groove communicating with the third mounting channel. The second limiting groove is located at one end of the third mounting channel away from the second mounting channel along the first direction. When the second push plate moves to the second position, the second limiting part is located in the second limiting groove.

[0021] In one embodiment, the moving mold includes a fastening assembly, which includes a movable part, an elastic reset part, a mating part, and a force-applying part. The movable part is movably disposed on one of the first push plate and the second push plate, the mating part is disposed on the other of the first push plate and the second push plate, the elastic reset part abuts against the movable part, and the force-applying part is fixed to the support plate.

[0022] During the process of the first push plate and the second push plate moving from the initial position to the first position, the movable member is connected to the mating member. When the first push plate and the second push plate move to the first position, the force-applying member abuts against the movable member, so that the movable member separates from the mating member by movement under the action of the force-applying member, and the elastic reset member generates an elastic deformation that resets the movable member.

[0023] In one embodiment, one of the first push plate and the second push plate has a mounting groove for accommodating the movable member. The mounting groove has an opening and a bottom wall on opposite sides. The movable member extends from the opening to the outside of the opening to connect with the mating member. The elastic reset member is telescopically disposed between the bottom wall and the movable member. Under the action of the force-applying member, the movable member moves toward the bottom wall to separate from the mating member.

[0024] Another embodiment of this application provides an injection mold, including:

[0025] Mold designation;

[0026] The aforementioned moving mold is detachably connected to the fixed mold, so that the moving mold, together with the fixed mold, at least through the moving mold core, constructs a cavity.

[0027] This application provides a moving mold and an injection mold. The secondary demolding mechanism of the moving mold includes a first push plate, a second push plate, and an ejector. The secondary demolding mechanism uses the combined movement of the first and second push plates and the individual movement of the second push plate to eject the molded product. Therefore, this secondary demolding mechanism not only has a simpler structure and fewer parts, but also almost no jamming during the ejection process. This not only reduces the failure rate of the moving mold and makes maintenance easier, but also improves the production stability of the molded product and shortens the molding cycle. Furthermore, the travel distances of the first and second push plates from their initial positions to the first position, and the travel distance of the second push plate from the first position to the second position, are relatively short in this type of secondary demolding mechanism. Therefore, the secondary demolding mechanism requires relatively little movement space in the first direction, which is also the thickness direction of the moving mold. Thus, by adopting the secondary demolding mechanism of this application embodiment, the thickness dimension of the moving mold can be reduced, thereby reducing the thickness dimension of the entire injection mold accordingly. This saves on the material used in the injection mold and allows the injection mold to be used with relatively small injection molding machines, thereby reducing both production energy consumption and the overall cost of injection molding.

Detailed Implementation

[0036] In the description of the embodiments in this application, it should be noted that the terms "first direction" and "second direction" are based on the appended... Figure 1 The orientation or positional relationship shown is merely for the convenience of describing the embodiments of this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application.

[0037] This application provides an injection mold 100. Please refer to [link / reference]. Figure 1 The injection mold 100 includes a fixed mold (not shown) and a moving mold 10.

[0038] Please see Figure 1The moving mold 10 in this embodiment includes a support plate 11, a moving mold core 12, and a secondary demolding mechanism 13.

[0039] The support plate 11 has a first side and a second side opposite to each other along a first direction. The moving mold core 12 is fixed to the support plate 11 and protrudes from the first side of the support plate 11.

[0040] The moving mold 10 and the fixed mold can be separably connected so that the moving mold 10 and the fixed mold together construct a cavity at least through the moving mold core 12.

[0041] Molded products 200 can be manufactured by injecting injection molding raw materials into the cavity.

[0042] Depending on the different structures of the molded product 200, the cavity can be constructed by the moving mold core 12 and the fixed mold, or it can be constructed by the moving mold core 12, other molding components of the moving mold 10, and the fixed mold.

[0043] The moving mold 10 closes by docking with the fixed mold, and opens by separating from the fixed mold. After opening, the molded product 200 is formed. Figure 1 The image shown is retained on the moving mold core 12.

[0044] The secondary demolding mechanism 13 is used to remove the molded product 200 that remains on the moving mold core 12 after the mold is opened.

[0045] Please see Figure 1 The secondary demolding mechanism 13 is disposed on the first side of the support plate 11. The secondary demolding mechanism 13 includes a push plate assembly and a pusher 133. The push plate assembly includes a separable first push plate 131 and a second push plate 132. The second push plate 132 is located on the side of the first push plate 131 away from the support plate 11 along the first direction. Both the first push plate 131 and the second push plate 132 can move along the first direction. The pusher 133 is fixed to the first push plate 131 and protrudes from the side of the second push plate 132 away from the support plate 11 along the first direction.

[0046] Please see Figure 2 and Figure 4 The first push plate 131 and the second push plate 132 move together to the first position in the direction away from the support plate 11 under the action of the thrust, so that the pusher 133 pushes the molded product 200 retained on the moving mold core 12 to the first ejection position under the drive of the first push plate 131.

[0047] Please see Figure 6 The second push plate 132 separates from the first push plate 131 at the first position and moves to the second position in the direction away from the first push plate 131 under the action of the thrust, so as to push the molded product 200 in the first ejection position to the demolding position.

[0048] Specifically, both the first push plate 131 and the second push plate 132 are plate-shaped structures.

[0049] Figure 1 The first push plate 131 and the second push plate 132 shown are respectively sleeved on the moving mold core 12, so that the movement of the first push plate 131 and the second push plate 132 can be guided by the moving mold core 12, thereby ensuring that the first push plate 131 and the second push plate 132 can move smoothly.

[0050] In other embodiments, at least one of the first push plate 131 and the second push plate 132 may not be sleeved on the moving mold core 12. For example, at least one of the first push plate 131 and the second push plate 132 may be disposed on the periphery of the moving mold core 12.

[0051] Figure 1 The secondary demolding mechanism 13 shown relies on the ejection system of the injection molding machine to apply the thrust. In other embodiments, the injection mold 100 may also be provided with a corresponding drive mechanism, which applies the thrust to the secondary demolding mechanism 13.

[0052] The secondary demolding mechanism consists of 13 parts that push the product through two stages to form product 200. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 4 The secondary demolding mechanism 13 first pushes and forms the product 200 by causing the first push plate 131 and the second push plate 132 to move together from the initial position along the first direction away from the support plate 11 under the action of the pushing force. When the first push plate 131 and the second push plate 132 reach the first position (i.e. Figure 4 (The positions of the first push plate 131 and the second push plate 132 in the middle), the ejector 133, driven by the first push plate 131, pushes the molded product 200 retained on the moving mold core 12 to the first ejection position (i.e., Figure 4 (The position of the molded product 200 in the middle), at this time the molded product 200 is only partially separated from the moving mold core 12.

[0053] Please see Figure 6 The secondary demolding mechanism 13 pushes the product 200 a second time by causing the second push plate 132 to move in the first direction away from the first push plate 131 under the action of the pushing force. That is, the second push plate 132 separates from the first push plate 131 at the first position, and continues to move under the action of the pushing force, while the first push plate 131 remains at the first position. When the second push plate 132 reaches the second position (i.e.,...)... Figure 6 The second push plate 132 is located at the position of the molded product 200. The second push plate 132 pushes the molded product 200 from the first ejection position to the demolding position (i.e., the second ejection position is located at the first ejection position). Figure 6(The location of the molded product 200 in the middle).

[0054] After the molded product 200 is pushed to the demolding position, a transfer mechanism such as a robot can be used to remove the molded product 200 from the moving mold. Then, the first push plate 131 and the second push plate 132 are controlled to reset (that is, the first push plate 131 and the second push plate 132 are controlled to return to their initial positions before being pushed to the first position). After the first push plate 131 and the second push plate 132 are reset, the moving mold 10 and the fixed mold are closed, and the next round of injection molding can continue.

[0055] Since the secondary demolding mechanism 13 of this application embodiment uses the combined movement of the first push plate 131 and the second push plate 132, as well as the individual movement of the second push plate 132, to push the molded product 200, this secondary demolding mechanism 13 not only has a simpler structure and fewer parts, but also almost no jamming during the pushing process. This not only reduces the failure rate of the moving mold 10 and makes maintenance easier, but also improves the production stability of the molded product 200 and shortens the molding cycle. Furthermore, the travel distances of the first push plate 131 and the second push plate 132 from the initial position to the first position, and the travel distance of the second push plate 132 from the first position to the second position, of the secondary demolding mechanism 13 are relatively short. Therefore, the secondary demolding mechanism 13 requires relatively little movement space in the first direction. The first direction is also the thickness direction of the moving mold 10. Therefore, by adopting the secondary demolding mechanism 13 of this application embodiment, the thickness dimension of the moving mold 10 can be reduced, thereby reducing the thickness dimension of the entire injection mold 100 accordingly. This saves material for the injection mold 100 and allows the injection mold 100 to be used with relatively small injection molding machines, thereby reducing production energy consumption and the overall cost of injection molding.

[0056] In addition, some molded products 200 have structures such as deep cavities and narrow grooves that require inserts to form, for example, Figure 6 The groove 200b of the molded product 200 shown is a narrow groove. Therefore, for this type of molded product 200, the ejector 133 can be a moving mold insert. That is, in addition to ejecting the molded product 200, the ejector 133 can also be used as a moving mold insert, for example... Figure 1 The pusher 133 shown is also used to construct the groove 200b of the molded product 200. As a result, there is no need to set up an insert separately, which can reduce the number of parts of the moving mold 10 and save the production cost of the injection mold 100.

[0057] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 6The moving mold core 12 may have a first molding surface 12a and a second molding surface 12b for constructing the molded product 200. The first molding surface 12a is located on the side of the moving mold core 12 away from the support plate 11 along the first direction, and the second molding surface 12b is located on the outer periphery of the moving mold core 12. When the first push plate 131 and the second push plate 132 are in the initial position, the first push plate 131 and the second push plate 132 are located between the support plate 11 and the second molding surface 12b, and on the projection plane perpendicular to the first direction, the projection of the second push plate 132 at least partially coincides with the projection of the portion of the molded product 200 constructed by the second molding surface 12b.

[0058] Specifically, the first molding surface 12a and the second molding surface 12b of the moving mold core 12 are used to directly contact the molding material to construct the molded product 200. The first molding surface 12a and the second molding surface 12b are actually part of the inner wall surface of the cavity.

[0059] by Figure 1 , Figure 2 , Figure 4 and Figure 6 Taking the molded product 200 as an example, the molded product 200 has a bottom wall 201 and a side wall 202. The bottom wall 201 and the side wall 202 enclose a receiving cavity 200a. The first molding surface 12a is used to construct the bottom wall 201, and the second molding surface 12b is used to construct the side wall 202. After the mold is opened, the molded product 200 is upside down on the moving mold core 12. The first molding surface 12a is in contact with the bottom wall 201, and the second molding surface 12b is in contact with the side wall 202.

[0060] Please see Figure 1 When the first push plate 131 and the second push plate 132 are in their initial positions (i.e. Figure 1 The first push plate 131 and the second push plate 132 are located between the support plate 11 and the second forming surface 12b. In other words, the first push plate 131 and the second push plate 132 will not block the second forming surface 12b, and the first push plate 131 and the second push plate 132 will not affect the forming of the side wall 202.

[0061] Meanwhile, on the projection plane perpendicular to the first direction, the projection of the second push plate 132 at least partially coincides with the projection of the part of the molded product 200 constructed by the second molding surface 12b. That is, at least a part of the second push plate 132 is toward the part of the molded product 200 constructed by the second molding surface 12b, i.e., at least a part of the second push plate 132 is toward the side wall 202.

[0062] Please see Figure 2 and Figure 4The pusher 133 pushes the molded product 200 by moving in a direction protruding from the first molding surface 12a. In other words, the pusher 133 pushes the molded product 200 to the first ejection position by pushing the bottom wall 201 of the molded product 200.

[0063] Please see Figure 6 When the second push plate 132 moves to the second position, the distance between the second push plate 132 and the support plate 11 along the first direction is greater than the distance between the second forming surface 12b and the support plate 11 along the first direction. In other words, the second push plate 132 pushes the side wall 202 of the forming product 200 to the demolding position by pushing the forming product 200.

[0064] Further, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 The ejector 133 can be located on one side of the moving mold core 12 along a second direction, which is perpendicular to the first direction. The ejector 133 can have a third molding surface 133a on the side of the moving mold core 12 along the second direction for constructing the molded product 200. When the first ejector plate 131 and the second ejector plate 132 are in their initial positions, the first ejector plate 131 and the second ejector plate 132 are located between the support plate 11 and the third molding surface 133a, and on the projection plane, the projection of the second ejector plate 132 at least partially coincides with the projection of the portion of the molded product 200 constructed by the third molding surface 133a.

[0065] Specifically, the third forming surface 133a of the pusher 133 is also used to directly contact the forming material to construct the formed product 200.

[0066] by Figure 1 , Figure 2 , Figure 4 and Figure 6 Taking the molded product 200 shown as an example, the second molding surface 12b of the moving mold core 12 in the figure forms part of the side wall 202 of the molded product 200, while the third molding surface 133a of the ejector 133 forms another part of the side wall 202 of the molded product 200. That is to say, the third molding surface 133a is actually also part of the inner wall surface of the cavity.

[0067] Please see Figure 1 When the first push plate 131 and the second push plate 132 are in their initial positions, the first push plate 131 and the second push plate 132 are also located between the support plate 11 and the third forming surface 133a, that is, the first push plate 131 and the second push plate 132 will not affect the forming of the side wall 202 where the third forming surface 133a is located.

[0068] Simultaneously, on the projection plane perpendicular to the first direction, the projection of the second pusher plate 132 can at least partially coincide with the projection of the portion of the molded product 200 constructed through the third molding surface 133a. That is, at least a portion of the second pusher plate 132 is directed towards the portion of the molded product 200 constructed through the third molding surface 133a, i.e., at least a portion of the second pusher plate 132 is directed towards the sidewall 202 located at the third molding surface 133a. Therefore, the second pusher plate 132 can simultaneously apply a pushing force (e.g., ...) to both the sidewall 202 of the molded product 200 located at the second molding surface 12b and the sidewall 202 located at the third molding surface 133a. Figure 6 As shown in the figure, this ensures that the molded product 200 can be pushed to the demolding position more stably.

[0069] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 The moving mold 10 may include a first limiting member 14 and a second limiting member 15. The first limiting member 14 has a first rod portion 141 and a first limiting portion 142 disposed at one end of the first rod portion 141. The second limiting member 15 has a second rod portion 151 and a second limiting portion 152 disposed at one end of the second rod portion 151. The end of the first rod portion 141 away from the first limiting portion 142 and the end of the second rod portion 151 away from the second limiting portion 152 are respectively connected to the support plate 11. The distance between the first limiting portion 142 and the support plate 11 along the first direction is smaller than the distance between the second limiting portion 152 and the support plate 11 along the first direction.

[0070] Please see Figure 4 When the first push plate 131 and the second push plate 132 move to the first position, the first limiting part 142 abuts against the first push plate 131. Please refer to Figure 6 When the second push plate 132 moves to the second position, the second limiting part 152 abuts against the second push plate 132.

[0071] Specifically, the first rod portion 141 is used to support the first limiting portion 142, and the cross-sectional area of ​​the first limiting portion 142 perpendicular to the first direction is greater than the cross-sectional area of ​​the first rod portion 141 perpendicular to the first direction. In other words, the first limiting portion 142 protrudes from the side wall surface of the first rod portion 141, so that the first limiting portion 142 can abut against the first push plate 131.

[0072] Similarly, the second rod portion 151 is used to support the second limiting portion 152, and the cross-sectional area of ​​the second limiting portion 152 perpendicular to the first direction is greater than the cross-sectional area of ​​the second rod portion 151 perpendicular to the first direction. In other words, the second limiting portion 152 protrudes from the side wall surface of the second rod portion 151, so that the second limiting portion 152 can abut against the second push plate 132.

[0073] By setting the first limiting member 14 and the second limiting member 15, it is possible to better ensure that the first push plate 131 and the second push plate 132 reach the first position when the secondary demolding mechanism 13 pushes the molded product 200 for the first time, and to better ensure that the second push plate 132 reaches the second position when the secondary demolding mechanism 13 pushes the molded product 200 for the second time. Thus, it is possible to ensure that the molded product 200 can be pushed to the demolding position in a relatively simple way.

[0074] Further, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 In some embodiments, the first push plate 131 may have a first mounting channel 131a extending along a first direction, and the second push plate 132 may have a clearance channel 132a extending along the first direction and communicating with the first mounting channel 131a. The cross-sectional area of ​​the clearance channel 132a perpendicular to the first direction is larger than the cross-sectional area of ​​the first mounting channel 131a perpendicular to the first direction. The first rod portion 141 passes through the first mounting channel 131a, and the clearance channel 132a avoids the first limiting portion 142.

[0075] Please see Figure 1 , Figure 2 , Figure 4 and Figure 6 The first rod 141 passes through the first mounting channel 131a and can also be used to guide the movement of the first push plate 131 and the second push plate 132 to ensure that the first push plate 131 and the second push plate 132 can move smoothly. The avoidance channel 132a avoids the first limiting part 142, so that the first limiting part 142 will not obstruct the movement of the second push plate 132 from the first position to the second position.

[0076] for Figure 1 , Figure 2 , Figure 4 and Figure 6In the moving mold 10 shown, since the stroke of the first push plate 131 and the second push plate 132 from the initial position to the first position is relatively short, the first limiting part 142 is located in the clearance channel 132a when the first push plate 131 and the second push plate 132 are in the initial position. It can be understood that in other embodiments, if the stroke of the first push plate 131 and the second push plate 132 from the initial position to the first position is relatively long, then when the first push plate 131 and the second push plate 132 are in the initial position, the first limiting part 142 may also extend to the end of the clearance channel 132a away from the first mounting channel 131a, and the first limiting part 142 re-enters the clearance channel 132a during the process of the first push plate 131 and the second push plate 132 moving from the initial position to the first position.

[0077] Additionally, please see Figure 1 , Figure 2 , Figure 4 and Figure 6 In some embodiments, the first push plate 131 may also have a first limiting groove 131c that communicates with the first mounting channel 131a and the avoidance channel 132a respectively. When the first push plate 131 and the second push plate 132 move to the first position, the first limiting part 142 is located in the first limiting groove 131c. That is, the first limiting part 142 can be limited by setting the first limiting groove 131c on the first push plate 131, so as to better ensure that the first push plate 131 is not tilted when the first limiting part 142 abuts against the first push plate 131.

[0078] Please see Figure 1 , Figure 2 , Figure 4 and Figure 6 In some embodiments, the first push plate 131 may also have a second mounting channel 131b extending along the first direction, and the second push plate 132 may have a third mounting channel 132b extending along the first direction and communicating with the second mounting channel 131b. The second rod portion 151 passes through the second mounting channel 131b and the third mounting channel 132b. That is, the second rod portion 151 may also be used to guide the movement of the first push plate 131 and the second push plate 132 to ensure that the first push plate 131 and the second push plate 132 can move smoothly.

[0079] Similarly, please see Figure 1 , Figure 2 , Figure 4 and Figure 6In some embodiments, the second push plate 132 may also have a second limiting groove 132c communicating with the third mounting channel 132b. The second limiting groove 132c is located at one end of the third mounting channel 132b away from the second mounting channel 131b in the first direction. When the second push plate 132 moves to the second position, the second limiting part 152 is located in the second limiting groove 132c. That is, the second limiting part 152 can also be limited by setting the second limiting groove 132c on the second push plate 132, so as to better ensure that the second push plate 132 is not tilted when the second limiting part 152 abuts against the second push plate 132.

[0080] In some embodiments, please refer to Figures 1 to 6 The moving mold 10 may include a fastening assembly 16, which includes a movable part 161, an elastic reset part 162, a mating part 163, and a force-applying part 164. Figures 1 to 6 The movable part 161 is movably disposed on the first push plate 131, and the mating part 163 is disposed on the second push plate 132. In other embodiments, the movable part 161 may be movably disposed on the second push plate 132, and the mating part 163 may be disposed on the first push plate 131.

[0081] Movable component 161 is a component that can move. Figures 1 to 6 The mating member 163 is a fixed component that cannot move. In other embodiments, the mating member 163 may also be a movable component.

[0082] Please see Figure 3 and Figure 5 The elastic reset member 162 abuts against the movable member 161, and the force-applying member 164 is fixed to the support plate 11. The elastic reset member 162 is an elastic member such as a spring or elastic silicone that can produce elastic deformation, while the force-applying member 164 is used to apply force to the movable member 161.

[0083] Please see Figure 2 and Figure 3 During the process of the first push plate 131 and the second push plate 132 moving from the initial position to the first position, the movable part 161 is connected to the mating part 163. That is to say, the movable part 161 is connected to the mating part 163, so that the first push plate 131 and the second push plate 132 can be connected as a whole and move together.

[0084] Figure 2 and Figure 3 The mating part 163 shown is connected to the movable part 161 by abutting against it. In other embodiments, the mating part 163 is also connected to the movable part 161 by means of hooking, snapping, or other methods.

[0085] Please see Figure 3 and Figure 6 The mating component 163 has a mating portion 163a that connects with the movable component 161. When the first push plate 131 and the second push plate 132 in the figure are in their initial positions, the mating component 163 is not connected to the movable component 161. That is, the mating portion 163a is in a position separated from the movable component 161. The thrust is actually applied to the second push plate 132. That is, the second push plate 132 moves a certain distance away from the first push plate 131 under the action of the thrust before the mating portion 163a connects with the movable component 161. It can be understood that in some other embodiments, when the first push plate 131 and the second push plate 132 are in their initial positions, the mating component 163 can also connect with the movable component 161. In this case, the thrust can also be applied to the first push plate 131.

[0086] Please continue reading. Figure 4 and Figure 5 When the first push plate 131 and the second push plate 132 move to the first position, the force-applying member 164 abuts against the movable member 161, so that the movable member 161 separates from the mating member 163 under the action of the force-applying member 164, and the elastic reset member 162 generates an elastic deformation that resets the movable member 161. In other words, during the movement of the first push plate 131 and the second push plate 132 from the initial position to the first position, the force-applying member 164 does not apply force to the movable member 161, thus allowing the movable member 161 to remain connected with the mating member 163. However, when the first push plate 131 and the second push plate 132 move to the first position, the force-applying member 164 can abut against the movable member 161 to apply force to the movable member 161, thereby allowing the movable member 161 to separate from the mating member 163. After the movable member 161 separates from the mating member 163, the second push plate 132 also separates from the first push plate 131 accordingly, allowing the second push plate 132 to move towards the second position. In addition, the movement of the movable member 161 also causes the elastic reset member 162 to undergo corresponding elastic deformation. After the force-applying member 164 separates from the movable member 161, the movable member 161 can reset under the elastic force of the elastic reset member 162.

[0087] Furthermore, with Figures 1 to 6Taking the moving mold 10 shown as an example, the first push plate 131 in the figure has a mounting groove 131d for accommodating the movable part 161. The mounting groove 131d has an opening 131d1 and a bottom wall 131d2 on opposite sides. The movable part 161 extends from the opening 131d1 to connect with the mating part 163. An elastic reset member 162 is telescopically disposed between the bottom wall 131d2 and the movable part 161. Under the action of the force-applying member 164, the movable part 161 moves towards the bottom wall 131d2 to separate from the mating part 163. In other words, the force-applying member 164 can push the movable part 161, causing it to retract into the mounting groove 131d. After the movable part 161 retracts into place, it can separate from the mating part 163. In addition, during the retraction of the movable part 161, the elastic reset part 162 is compressed. After the force-applying part 164 separates from the movable part 161, the elastic reset part 162 extends to push the movable part 161 in a direction away from the bottom wall 131d2, thereby allowing the movable part 161 to reset.

[0088] It is understood that if the movable part 161 is disposed on the second push plate 132, then the second push plate 132 has a mounting groove 131d for accommodating the movable part 161. The movement mode of the movable part 161 and the deformation mode of the elastic reset part 162 are the same as those in the above embodiment, and will not be described again here.

[0089] Additionally, it should be noted that the fastening assembly 16 is not limited to the structural form described in the above embodiments. For example, in some other embodiments, the movable member 161 may be rotatably disposed on one of the first push plate 131 and the second push plate 132, and the elastic reset member 162 may be an elastic member capable of torsional deformation, such as a torsion spring. Under the action of the force-applying member 164, the movable member 161 rotates in a direction away from the mating member 163 to separate from the mating member 163. At the same time, during the rotation of the movable member 161, the elastic reset member 162 generates a restoring torque opposite to its torsional direction. After the force-applying member 164 separates from the movable member 161, the movable member 161 is reset under the action of the restoring torque of the elastic reset member 162.

[0090] In other embodiments, the moving mold 10 may not have the latching assembly 16. For example, when the first push plate 131 and the second push plate 132 are in their initial positions, the second push plate 132 can be stacked on top of the first push plate 131. A pushing force is applied to the first push plate 131 to push the first push plate 131 and the second push plate 132 together toward the first position. When the first push plate 131 and the second push plate 132 are in the first position, only the second push plate 132 needs to be pushed individually to separate the second push plate 132 from the first push plate 131.
