Description

Technical Field

[0001] The present application relates to the field of injection molding technology, and in particular to a mold structure and injection molding equipment. Background Art

[0002] Currently, in order to meet the needs of users, many display products are developing in the direction of narrow borders. In order to meet the structural design requirements of narrow borders, the border structure of the display module is usually prepared by injection molding process.

[0003] However, the display module with narrow frame design has a thin frame thickness. When the frame is provided with an oblique pin hook structure, there may be a problem that the oblique pin hook structure is not easy to demould. Therefore, how to ensure that the frame provided with the oblique pin hook structure is smoothly demoulded from the mold has become an urgent problem to be solved. Utility Model Content

[0004] In view of this, the purpose of the present application is to provide a mold structure and an injection molding device.

[0005] Based on the above-mentioned purpose, the first aspect of the present application provides a mold structure, including: a first sliding member, including a first side wall, the first sliding member is provided with a first groove for forming a molding cavity at least on the first side wall; a stop module, slidably connected to the first sliding member, the stop module includes a first stop side wall, the first stop side wall is provided with a second groove for forming a molding cavity; the stop module has a mold closing state and an initial mold opening state; when the stop module is in the mold closing state, the first groove and the second groove are aligned, and the first side wall is aligned with the first stop side wall; when the stop module is in the initial mold opening state, the first groove and the second groove are misaligned, and the first side wall is misaligned with the first stop side wall.

[0006] Optionally, the first positioning member is connected with a guide pin, and the stop module is provided with a stop guide through hole, the stop guide through hole comprises a long hole extending along a first direction, and the stop module is mounted on the guide pin through the long hole; the first direction is a direction intersecting with the first side wall and away from the opening of the second groove.

[0007] Optionally, a accommodating cavity is provided inside the first sliding member, and the accommodating cavity passes through the first side wall to form an accommodating opening on the first side wall; the stop module is installed in the accommodating cavity, and part of the stop module can be moved out of the accommodating cavity through the accommodating opening to switch the stop module from the mold closing state to the initial mold opening state.

[0008] Optionally, the mold structure further includes a mold core. When the stop module is in the mold-closed state, the first slider is embedded in the mold core; the end of the first slider close to the first groove is defined as the top end of the first slider. When the top end of the first slider moves away from the mold core in the second direction, the stop module switches from the mold-closed state to the initial mold-opening state; wherein, the second direction intersects with the first direction.

[0009] Optionally, the mold core is provided with an embedding through-hole penetrating the mold core in the second direction, and the first slider can be embedded in the mold core through the embedding through-hole.

[0010] Optionally, a lifter rod is connected to the bottom end of the first slider, and the lifter rod is configured to drive the first slider to reciprocate in the second direction.

[0011] Optionally, a guiding structure is provided on the inner wall of the embedding through-hole far from the first side wall. The guiding structure is used to drive the first slider and the stop module to move in the reverse direction of the first direction when the first slider approaches the mold core in the second direction, so that the stop module switches to the mold-closed state.

[0012] Optionally, the guiding structure is a wedge-shaped structure with the tip facing the top end of the first slider.

[0013] Optionally, a chamfer structure is provided at the bottom of the stop module far from the first stop side wall; along the first direction, at least part of the chamfer structure protrudes from the side wall of the first slider; the stop module can cooperate with the guiding structure through the chamfer structure.

[0014] Optionally, the stop module further has a fully mold-opened state. When the stop module is in the fully mold-opened state, the first slider drives the stop module to move in the first direction.

[0015] Optionally, when the stop module is in the fully mold-opened state, the first groove and the second groove are misaligned in the first direction, and the misalignment distance is greater than 0.5 mm and less than 1.5 mm.

[0017] As can be seen from the above, for the mold structure and injection molding equipment provided in this application, by providing a stop module slidably connected to the first slider, during demolding, the first groove of the first slider and the second groove of the stop module can be misaligned, so that the stop module and the first slider are separated from the product successively. Since when one of the first slider and the stop module is just separated from the product, the other is still in contact with the product, on the one hand, the pulling force generated on the product when the mold structure is separated from the product can be reduced, which helps to prevent the product from being pulled and deformed by the mold structure; on the other hand, the part of the mold structure that is separated from the product later can also play a certain positioning and stabilizing role on the product, preventing the product from moving and preventing the product from sticking to the part of the mold structure that is separated from the product first, which helps to improve the molding quality of the product, reduce the number of mold repairs and trial molds, shorten the mold development cycle, and reduce the development costs of the mold and the product.

Detailed implementation manners

[0040] To make the objectives, technical solutions and advantages of the present application clearer and more understandable, the following further elaborates on the present application in detail with reference to specific embodiments and the accompanying drawings.

[0041] It should be noted that: Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components set forth in these embodiments do not limit the scope of the present application.

[0042] Meanwhile, it should be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships.

[0043] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way a limitation on the present application and its application or use.

[0044] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be of the ordinary meaning as understood by those of ordinary skill in the art to which the present application pertains. The "first", "second", and similar terms used in the embodiments of the present application do not denote any order, quantity, or importance, but are merely used to distinguish different components. The terms such as "including" or "comprising" mean that the elements or items appearing before the term cover the elements or items listed after the term and their equivalents, without excluding other elements or items. The terms such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms such as "upper", "lower", "left", "right", etc. are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0045] The angled pin hook structure 210 may include a conventional angled pin hook structure 11 and a stop angled pin hook structure 12. As Figure 1 , Figure 1 shows a sectional view of the frame 10 provided with the conventional angled pin hook structure 11, and the conventional angled pin hook structure 11 is directly provided on the side wall of the frame 10. As Figure 2 , Figure 2 shows a sectional view of the frame 10 provided with the stop angled pin hook structure 12, and the bottom of the stop angled pin hook structure 12 is connected to the frame 10. In order to ensure that the angled pin hook structure 210 can be smoothly separated from the injection mold, in some embodiments, a relatively large space needs to be reserved around the angled pin hook structure 210, and at the same time, the angled pin hook structure 210 needs to have a relatively large forming angle, and it is necessary to ensure that the setting base of the angled pin hook structure 210 (such as Figure 1 the side wall of the frame 10 in Figure 2 or the part where the lower part of the stop angled pin hook structure 12 in

[0046] is connected to the frame 10) has relatively high strength. Figure 1Taking the shown structure as an example, during demolding, the mold can move along the X direction in the figure. During the movement of the mold, the mold will generate a pulling force along the X direction on the side wall of the frame 10 and the conventional angled pin hook structure 11. In order to separate the mold from the conventional angled pin hook structure 11, it is necessary for the conventional angled pin hook structure 11 to remain in place without being driven by the pulling force to move along the X direction.

[0047] In order for the conventional angled pin hook structure 11 to remain stationary, one way is to make the side wall of the frame 10, which is the setting basis of the conventional angled pin hook structure 11, have a relatively high strength to prevent the side wall of the frame 10 from deforming under the action of the pulling force. When the side wall can maintain its original structure under the action of the pulling force, then the conventional angled pin hook structure 11 provided on the side wall will naturally not move either.

[0048] However, the applicant's research found that in order to make the side wall of the frame 10 have a relatively high strength, it is necessary to increase the thickness of the frame 10. However, if the thickness of the frame 10 increases, the design requirements of the narrow frame cannot be met.

[0049] In view of this, as Figure 3 、 Figure 4 、 Figure 5 ,the embodiment of the present application provides a mold structure 100, including: a first slider 110, including a first side wall 111, and the first slider 110 is provided with a first groove 112 for forming a molding cavity at least on the first side wall 111; a stop module 120, slidably connected to the first slider 110, and the stop module 120 includes a first stop side wall 122, and the first stop side wall 122 is provided with a second groove 121 for forming a molding cavity.

[0050] The stop module 120 has a mold closing state and an initial mold opening state; when the stop module 120 is in the mold closing state, as Figure 6 and Figure 7 ,the first groove 112 and the second groove 121 are aligned, and the first side wall 111 is aligned with the first stop side wall 122; when the stop module 120 is in the initial mold opening state, as Figure 8 and Figure 9 ,the first groove 112 and the second groove 121 are misaligned, and the first side wall 111 is misaligned with the first stop side wall 122.

[0051] Exemplarily, as Figure 3 and Figure 4, the mold structure 100 may include a male mold fixing plate 130. On one side of the male mold fixing plate 130, there are two spaced mold feet 140. On the side of the two mold feet 140 away from the male mold fixing plate 130, there is a male mold plate 150, and the male mold plate 150 is connected to both mold feet 140 at the same time. The male mold plate 150 is connected with a mold core 160. Exemplarily, on the surface of the male mold plate 150 away from the male mold fixing plate 130, there is an installation groove, and at least part of the mold core 160 is installed in the male mold plate 150 through the installation groove. The exposed surface of the mold core 160 is provided with a groove for forming a molding cavity. During injection molding, the flowing raw material is injected into the molding cavity, and after the raw material is cured, the product 200 (such as the frame 10) can be formed.

[0052] Exemplarily, such as Figure 3 , between the male mold plate 150 and the male mold fixing plate 130, there is a thimble fixing plate 180 and a thimble plate 170. The thimble plate fixing plate and the thimble plate 170 are located between the two mold feet 140, and the thimble plate 170 is closer to the male mold fixing plate 130 than the thimble fixing plate 180. Exemplarily, driven by an injection molding machine, the thimble fixing plate 180 and the thimble plate 170 can move closer to or away from the male mold plate 150 along the thickness direction of the mold core 160 (such as Figure 3 the Z1 direction in). Exemplarily, a return spring is also arranged between the thimble fixing plate 180 and the male mold plate 150, and the elastic force provided by the return spring can drive the thimble fixing plate 180 and the thimble plate 170 to move away from the male mold plate 150 to a preset return position (i.e., the position close to the male mold fixing plate 130).

[0053] Exemplarily, the thimble fixing plate 180 can be installed with thimbles and tie rods, and the thimbles and tie rods can pass through the mold core 160. When the thimble plate 170 and the thimble fixing plate 180 move closer to the male mold plate 150 along the thickness direction of the mold core 160, the thimbles can abut against the cured product 200 to eject the product 200 from the groove of the mold core 160 to realize demolding. One end of the tie rod away from the thimble fixing plate 180 can be connected with a lifter, and the lifter can be provided with a groove for cooperating with the groove on the mold core 160 to form a molding cavity. The groove on the lifter is used to form a local structure on the product 200 (such as the angled pin hook structure 210), and the tie rod can drive the lifter to move along a preset inclined direction (relative to the thickness direction of the mold core 160) to realize the lifter can be demolded from the product 200.

[0054] Exemplarily, the stop module 120 can be arranged inside the first lifter 110, or connected to the side wall of the first lifter 110 adjacent to the first side wall 111.

[0055] Exemplarily, the mold core 160 may also be provided with a structure for driving the first slide member 110 to move when the stop module 120 is switched from the mold-closed state to the initial mold-opening state. For example, a guide rod or a spring, etc.

[0056] Exemplarily, the wall area of the first groove 112 (i.e., the direct contact area between the first slide member 110 and the product 200) is larger than the wall area of the second groove 121 (i.e., the direct contact area between the stop module 120 and the product 200); alternatively, the wall area of the first groove 112 is equal to the wall area of the second groove 121; alternatively, the wall area of the first groove 112 is smaller than the wall area of the second groove 121.

[0057] As Figure 6 , when the stop module 120 is in the mold-closed state, the ejector plate 170 and the ejector retainer plate 180 are located at the reset position close to the male mold fixing plate 130. As Figure 7 , at this time, the first groove 112 and the second groove 121 are aligned to jointly form a part of the molding cavity, preparing the mold for injection molding. Then, a flowing material for forming the product 200 can be injected into the first groove 112 and the second groove 121. After the flowing material is solidified, a partial structure of the product 200 can be formed. It should be noted that at this time, the wall of the first groove 112 and the wall of the second groove 121 are both in direct contact with the product 200.

[0058] Exemplarily, the material in the first groove 112 and the second groove 121 can be solidified to form an angled pin hook structure 210 on the product 200.

[0059] As Figure 8 , the ejector plate 170 and the ejector retainer plate 180 synchronously move from the reset position towards the male mold plate 150 along the thickness direction of the mold core 160 (such as Figure 8 the Z1 direction in Figure 9 ), and the stop module 120 is switched from the mold-closed state to the initial mold-opening state. Taking the structure shown in Figure 9 as an example for illustration, at this time, the first slide member 110 moves relative to the stop module 120 along a first direction (such as Figure 9 the X1 direction in Figure 9 , that is, the first direction is the direction intersecting the first side wall 111 and departing from the opening of the second groove 121). At this time, it can be that the stop module 120 remains stationary and the first slide member 110 moves along the first direction. Since the movements of the first slide member 110 and the stop module 120 are not synchronous, the first groove 112 and the second groove 121 are misaligned. As Figure 9It can be seen that when the stop module 120 is in the initial mold opening state, the first stop side wall 122 and the first side wall 111 are misaligned. It is understandable that the groove wall of the first groove 112 of the first slider 110 will separate from the product 200 prior to the stop module 120. In other words, when the first slider 110 just separates from the product 200, the stop module 120 still remains in contact with the product 200. The stop module 120 can position the product 200 to a certain extent, helping the product 200 to stay in the current position and preventing the product 200 from moving along the first direction with the first slider 110.

[0060] For the mold structure 100 provided by the embodiments of the present application, by arranging the slidably connected stop module 120 on the first slider 110, during demolding, the first groove 112 of the first slider 110 and the second groove 121 of the stop module 120 can be misaligned, so that the stop module 120 and the first slider 110 separate from the product 200 successively. Since when one of the first slider 110 and the stop module 120 just separates from the product 200, the other still remains in contact with the product 200, on the one hand, the pulling force generated on the product 200 when the mold structure 100 separates from the product 200 can be reduced, which helps to prevent the product 200 from being pulled and deformed by the mold structure 100; on the other hand, the part of the mold structure 100 that separates from the product 200 later can also position and stabilize the product 200 to a certain extent, prevent the product 200 from moving, and prevent the product 200 from sticking to the part of the mold structure 100 that separates from the product 200 first, which helps to improve the molding quality of the product 200, reduce the number of mold repairs and trial molds, shorten the mold development cycle, and reduce the development costs of the mold and the product 200.

[0061] As Figure 12 、 Figure 13 and Figure 14 shown, in some embodiments, an accommodation cavity 113 is provided inside the first slider 110, and the accommodation cavity 113 penetrates through to the first side wall 111 to form an accommodation opening 114 on the first side wall 111; the stop module 120 is installed in the accommodation cavity 113, and a part of the stop module 120 can move out of the accommodation cavity 113 through the accommodation opening 114, so that the stop module 120 is switched from the mold closing state to the initial mold opening state.

[0062] Exemplarily, the stop module 120 can be a plate-like structure or a block-like structure. When the stop module 120 is a plate-like structure, the first stop side wall 122 is the circumferential side wall of the plate-like structure.

[0063] Exemplarily, the cross-sectional shape of the accommodation opening 114 matches the cross-sectional shape of the first stop side wall 122.

[0064] Exemplarily, along the extension direction of the angle pin hook structure 210 (such asFigure 14 in the Y1 direction), the stop module 120 corresponds to the middle of the angled pin hook structure 210, so that the acting force provided by the stop module 120 on the angled pin hook structure 210 can act on the angled pin hook structure 210 more evenly.

[0065] Exemplarily, the accommodation cavity 113 also penetrates through to the opposite side wall of the first side wall 111 to form another opening of the accommodation cavity 113, that is, the accommodation cavity 113 penetrates through the first slider 110 along the first direction.

[0066] When the stop module 120 is in the mold closing state, the first stop side wall 122 can be flush with the first side wall 111 through the accommodation opening 114, so that the first groove 112 and the second groove 121 are aligned. When the stop module 120 is switched from the mold closing state to the initial mold opening state, the stop module 120 lags behind in movement relative to the first slider 110, and the first stop side wall 122 of the stop module 120 then moves out of the accommodation cavity 113 through the accommodation opening 114. At this time, the first stop side wall 122 and the first side wall 111 are misaligned. Correspondingly, the first groove 112 and the second groove 121 are misaligned, so that while the product 200 remains in contact with the groove wall of the second groove 121, it is separated from the groove wall of the first groove 112.

[0067] Installing the stop module 120 inside the first slider 110 can, while ensuring that the stop module 120 can achieve the above functions, also avoid the stop module 120 additionally occupying the internal space of the mold structure 100, which helps to make the overall structure of the mold structure 100 compact, with a simple appearance, convenient assembly, stable and reliable operation, and can achieve the structural function requirements with high quality. At the same time, since the stop module 120 is arranged inside the first slider 110, the stop module 120 will not have a great impact on the external shape structure of the first slider 110. Therefore, the first slider 110 and the stop module 120 of this embodiment have a wide range of applications, can be used to prepare products 200 of different sizes, meet the requirements of narrow borders and thin and light housings for display modules, and enable the structurally compact product 200 to be formed by an injection molding process.

[0068] Exemplarily, in order to enable the first row of components 110 to drive the stop module 120 to move after moving a certain distance, a groove extending in the first direction may be provided on one of the first row of components 110 and the stop module 120, and a convex structure extending into the groove may be provided on the other. When the convex structure slides in the groove, the first row of components 110 and the stop module 120 can move relative to each other. When the convex structure abuts against one end wall of the groove, the first row of components 110 drives the stop module 120 to move synchronously. Alternatively, the first row of components 110 and the stop module 120 are each provided with a convex structure, and the two convex structures can be spaced apart from each other. When the two convex structures move towards each other and do not contact, the first row of components 110 and the stop module 120 can move relative to each other. When the two convex structures contact, the first row of components 110 drives the stop module 120 to move synchronously.

[0069] For example Figure 13 、 Figure 15 、 Figure 16 、 Figure 17 and Figure 18 In some embodiments, a guide pin 115 is connected to the first row of components 110. The guide pin 115 is at least partially located in the receiving cavity 113, and the axis of the guide pin 115 is perpendicular to the first direction. The stop module 120 is provided with a stop guide through hole 123, and the stop guide through hole 123 includes a long hole extending in the first direction. The stop module 120 is sleeved on the guide pin 115 through the long hole of the stop guide through hole 123. When the first row of components 110 moves relative to the stop module 120 in the first direction until the guide pin 115 abuts against the side wall of the stop guide through hole 123 away from the second groove 121, the stop module 120 is switched from the initial mold opening state to the fully open mold state.

[0070] Exemplarily, for example Figure 15 the stop module 120 is a plate-like structure.

[0071] Exemplarily, for example Figure 16 the guide pin 115 can be a cylindrical structure with a uniform diameter, and the diameter of the guide pin 115 can be 3 mm.

[0072] Exemplarily, the guide pin 115 can be inserted into the receiving cavity 113 from the outside of the first row of components 110, and the end of the guide pin 115 does not protrude from the outer wall of the first row of components 110.

[0073] Exemplarily, when the stop module 120 is in the mold closing state, the guide pin 115 can abut against the side wall of the stop guide through hole 123 close to the second groove 121; alternatively, the guide pin 115 can be spaced from the side wall of the stop guide through hole 123 close to the second groove 121.

[0074] When the stop module 120 is in the mold closing state, the guide pin 115 is close to one end of the stop guiding through hole 123 near the second groove 121. When the stop module 120 is switched from the mold closing state to the initial mold opening state, the guide pin 115 moves along the extending direction of the stop guiding through hole 123 towards the other end of the stop guiding through hole 123, that is, the first slider 110 moves relative to the stop module 120 in the first direction.

[0075] The stop module 120 is switched from the mold closing state to the initial mold opening state by the guide pin 115 and the stop guiding through hole 123, which not only has a simple structure but also has a relatively low assembly difficulty, helping to further reduce the overall cost of the mold structure 100.

[0076] Such as Figure 10 and Figure 11 , in some embodiments, the stop module 120 further has a fully open mold state. When the stop module 120 is in the fully open mold state, the first slider 110 drives the stop module 120 to move in the first direction.

[0077] Such as Figure 10 , the ejector plate 170 and the ejector retainer plate 180 synchronously move closer to the male mold plate 150 along the thickness direction of the male mold plate 150 (such as the Z1 direction in Figure 10 ), and the stop module 120 is switched from the initial mold opening state to the fully open mold state. Such as Figure 11 , at this time, the first slider 110 continues to move in the first direction (such as the X1 direction in Figure 10 ), and when the first slider 110 moves a preset distance relative to the stop module 120, it will drive the stop module 120 to move synchronously, so that the stop module 120 is also separated from the product 200 after the first slider 110, so that the product 200 is demolded.

[0078] Such as Figure 13 , when the guide pin 115 moves to abut against the side wall of the end of the stop guiding through hole 123 far from the second groove 121, the first slider 110 will drive the stop module 120 to move synchronously through the guide pin 115, that is, the stop module 120 is switched from the initial mold opening state to the fully open mold state.

[0079] Such as Figure 3 and Figure 4 , in some embodiments, the mold structure 100 further includes a core 160. Such as Figure 6 and Figure 7 , when the first slider 110 is embedded in the core 160, the stop module 120 is in the mold closing state. Such as Figure 8 , Figure 9 , Figure 10 and Figure 11, the end of the first row member 110 near the first groove 112 is defined as the top end of the first row member 110. When the top end of the first row member 110 moves away from the mold core 160 along the second direction (such as Figure 8 and Figure 10 the Z1 direction in

[0080] ), the stop module 120 is sequentially switched from the mold-closed state to the initial mold-opening state and the fully open mold state; wherein, the second direction intersects with the first direction.

[0081] Exemplarily, the end of the stop module 120 near the second groove 121 is defined as the top end of the stop module 120.

[0082] Exemplarily, the second direction is perpendicular to the first direction. Figure 7 As

[0083] shown in Figure 20 , when the stop module 120 is in the mold-closed state, the first groove 112 and the second groove 121 are aligned and define a molding cavity with the mold core 160. Figure 20 The direction in Figure 8 and Figure 9 corresponds to the direction shown in Figure 20 . The first row member 110 (indicated by the black arrow in Figure 9 ) moves upward (i.e., moves away from the mold core 160 along the second direction, such as Figure 8 and Figure 9 the Z1 direction in Figure 20 ) while moving to the left (i.e., along the first direction, Figure 21 the X1 direction in Figure 21 ). The movements in the two directions are superimposed. Relative to the stationary mold core 160, the first row member 110 actually moves in a direction inclined upward to the left. And the stop module 120 (indicated by the center line arrow in

[0084] ) moves upward with the first row member 110 and remains stationary along the first direction, that is, the stop module 120 actually only moves upward relative to the stationary mold core 160. As Figure 11 shown in

[0085] , the line arrow in represents the relative movement between the stop module 120 and the first row member 110, and the stop module 120 moves to the right relative to the first row member 110.

[0084] As Figure 11 shown in

[0085] , in some embodiments, the mold core 160 is provided with an embedded through hole 161 penetrating along the second direction, and the first row member 110 can be embedded in the mold core 160 through the embedded through hole 161.

[0086] As Figure 6 , Figure 7 , Figure 8 , Figure 10 and Figure 11 , in some embodiments, a lifter pull rod 190 is connected to the bottom end of the first lifter 110, and the lifter pull rod 190 is configured to drive the first lifter 110 to reciprocate in a second direction (such as the Z1 direction in Figure 6 , Figure 7 , Figure 8 , Figure 10 and Figure 11 ).

[0087] Exemplarily, as Figure 17 and Figure 18 , a T-shaped groove 116 penetrating along a first direction is provided at the bottom of the first lifter 110, and a protruding structure 191 matching the T-shaped groove 116 is provided at the top of the lifter pull rod 190. After the protruding structure 191 is inserted into the T-shaped groove 116, the lifter pull rod 190 can drive the first lifter 110 to reciprocate in the second direction. At the same time, the first lifter 110 can also slide relative to the lifter pull rod 190 in the first direction.

[0088] Exemplarily, the bottom of the lifter pull rod 190 is connected to the ejector retainer plate 180 and / or the ejector plate 170, and the injection molding machine can drive the lifter pull rod 190 to move in the second direction through the ejector retainer plate 180 and the ejector plate 170.

[0089] Since the embedding through hole 161 penetrates the mold core 160 in the second direction, the lifter pull rod 190 can extend into the embedding through hole 161 from below the mold core 160 to push the first lifter 110 upward in the second direction, so that the first lifter 110 moves away from the mold core 160, and the stop module 120 is sequentially switched from the mold closing state to the initial mold opening state and the fully open mold state; or, the lifter pull rod 190 can pull the first lifter 110 downward from below the mold core 160, so that the first lifter 110 moves closer to the mold core 160, and the stop module 120 is sequentially switched from the fully open mold state to the initial mold opening state and the mold closing state.

[0090] As Figure 7 , Figure 8 and Figure 11 shown, in some embodiments, a guiding structure 162 is provided on the inner wall of the embedding through hole 161 far from the first side wall 111. When the first lifter 110 approaches the mold core 160 in the second direction, the guiding structure 162 is configured to drive the first lifter 110 and the stop module 120 to move in the reverse direction of the first direction, so that the stop module 120 is switched to the mold closing state.

[0091] Exemplarily, the guiding structure 162 is connected to the hole wall of the embedded through hole 161 that is away from the first side wall 111.

[0092] When the first row positioning member 110 approaches the mold core 160 along the second direction, the stop module 120 switches from the fully open mold state to the mold closing state.

[0093] As Figure 19 shown in the movement schematic diagram of the first row positioning member 110 and the stop module 120 switching from the fully open mold state to the mold closing state, Figure 19 the direction corresponds to Figure 11 the direction shown in Figure 19 . The first row positioning member 110 (indicated by the black arrow in Figure 19 ) moves downward (i.e., approaches the mold core 160 along the second direction) and moves to the right (i.e., in the reverse direction of the first direction) at the same time. The movements in the two directions are superimposed. Relative to the stationary mold core 160, the first row positioning member 110 actually moves in a direction inclined downward to the right. And the stop module 120 (indicated by the center line arrow in

[0094] As Figure 11 shown, in some embodiments, the guiding structure 162 is a wedge-shaped structure with the tip facing the top of the first row positioning member 110.

[0095] Taking Figure 11 the structure and direction shown as an example, along the first direction (such as the X1 direction in Figure 11 ), the size of the guiding structure 162 gradually increases from top to bottom. When the first row positioning member 110 drives the stop module 120 to move close to the mold core 160 along the second direction (i.e., in the reverse direction of the Z1 direction in Figure 11 , moving from top to bottom), the guiding structure 162 will continuously squeeze the first row positioning member 110 and the stop module 120 to drive the first row positioning member 110 and the stop module 120 to move in the reverse direction of the first direction until the first groove 112 of the first row positioning member 110 and the second groove 121 of the stop module 120 are aligned and redefine the molding cavity with the mold core 160.

[0096] As Figure 7 , Figure 11 , Figure 12 and Figure 13 shown, in some embodiments, a chamfer structure 124 is provided at the bottom of the stop module 120 that is away from the first stop side wall 122; along the first direction, at least part of the chamfer structure 124 protrudes from the side wall of the first row positioning member 110; the stop module 120 can cooperate with the guiding structure 162 through the chamfer structure 124.

[0097] Exemplarily, the chamfer structure 124 can be a round chamfer structure or an inclined chamfer structure.

[0098] During the process that the first row component 110 drives the stop module 120 to approach the mold core 160 along the second direction, after the chamfer structure 124 contacts the guiding structure 162, the guiding structure 162 will push the chamfer structure 124 in the reverse direction of the first direction to drive the stop module 120 to move in the reverse direction of the first direction until the second groove 121 of the stop module 120 is aligned with the first groove 112 of the first row component 110, and a molding cavity is jointly defined with the mold core 160, that is, the stop module 120 switches to the mold closing state.

[0099] By arranging the chamfer structure 124 at the bottom of the stop module 120, the driving of the stop module 120 by the guiding structure 162 can be made smoother, and the situation of jamming between the stop module 120 and the guiding structure 162 can be effectively avoided when the first row component 110 moves close to the mold core 160.

[0100] As Figure 13 shown, in some embodiments, when the stop module 120 is in the fully open mold state, the first groove 112 and the second groove 121 are offset along the first direction, and the offset distance is greater than 0.5 mm and less than 1.5 mm. In other words, when the stop module 120 switches from the mold closing state to the fully open mold state, the moving distance L of the first row component 110 relative to the stop module 120 along the first direction is greater than 0.5 mm and less than 1.5 mm.

[0101] Exemplarily, the moving distance L of the first row component 110 relative to the stop module 120 along the first direction can be 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm or 1.3 mm.

[0102] In order to realize the separation of the first row component 110 and the stop module 120 from the product 200 successively, it is necessary to ensure that the moving distance of the first row component 110 relative to the stop module 120 is appropriate during the process that the stop module 120 switches from the mold closing state to the fully open mold state. If the moving distance of the first row component 110 relative to the stop module 120 is too small, then when the stop module 120 switches to the fully open mold state (that is, when the stop module 120 moves with the first row component 110), there may be a situation where the first row component 110 is not completely separated from the product 200. If the moving distance of the first row component 110 relative to the stop module 120 is too large, then there may be a situation where when the first row component 110 stops moving along the first direction, the stop module 120 is still not completely separated from the product 200.
