[0001] The present application relates to the field of injection molds, in particular to an injection mold with a composite side slider mechanism. BACKGROUND
[0002] A mold is a tool used in the manufacture of shapes and sizes under the action of external force. It is widely used in blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure forging, and compression molding or injection molding of engineering plastics, rubber, ceramic and other products.
[0003] In related technologies, the part constituting the cavity in the mold at least includes a front mold core, a rear mold core, and an insert. The front mold core and the rear mold core open and close along the vertical direction to serve as the upper side wall and the lower side wall of the cavity. A plurality of inserts surround the circumferential side wall of the cavity. The movement mode of the insert depends on the structure of the circumferential side wall of the workpiece. According to the different movement modes, the inserts are divided into half inserts and line inserts. However, due to the different movement modes, in order to reduce interference, the two types of inserts cannot exist in one mold at the same time, so multiple processes are required to form different regions of the workpiece, resulting in low production efficiency for complex workpieces. SUMMARY

[0012] By adopting the technical scheme, when the front template and the rear template start to separate, the delay slide base gradually approaches the limiting block under the gravity of the delay slide base and the resistance transmitted by the row insert through the row guide rod. In this process, the delay slide base moves relative to the front template, but does not move relative to the rear template, so that the delay demolding of the row insert is realized.

An adaptive seat is arranged between the unit mounting frame and the adaptive guide rail, which is slidably sleeved on the adaptive guide rail. The adaptive seat is threadedly provided with a locking bolt, which abuts against the outer wall of the adaptive guide rail to lock the adaptive seat.
[0014] By adopting the technical scheme, due to the different structures of the workpieces, the distribution modes of the half inserts and the row inserts are different, and even the space ranges occupied by each half insert or row insert are different. Therefore, the positions of the half working group and the row working group can be freely changed by means of the cooperation among the adaptive seat, the adaptive guide rail and the locking bolt, so that different processing requirements can be adapted at a lower cost.

[0017] Preferably, the row insert is slidably provided with a row insert pin, and the movement direction of the row insert pin intersects with the movement direction of the row insert. A cooperative driving assembly is arranged between the half insert and the row insert pin. The cooperative driving assembly has a connected state and a separated state.

DETAILED DESCRIPTION
[0029] The application will be further described below in conjunction with the accompanying drawings. Figures 1-4 The application will be further described below in conjunction with the accompanying drawings.
[0030] The application discloses an injection mold with a composite lateral slider mechanism.
[0031] Referring to Figure 1 The injection mold with the composite lateral slider mechanism comprises a back mold plate 1, a front mold plate 2, a half guide rod 3, a time-delay sliding seat 4, a line position insert 42 and a time-delay limiting assembly 5. The back mold plate 1 is generally in the shape of a cuboid, and is usually fixed on a machine table and used for setting a product. The front mold plate 2 is slidably connected with the back mold plate 1 through a cylindrical guide rod, and is located above the back mold plate 1 to realize the opening and closing of the front mold plate 2 and the back mold plate 1. The half guide rod 3 is generally in the shape of a cylinder, and the upper end of the half guide rod 3 is fixedly connected with the front mold plate 2. The half guide rod 3 is obliquely extended, and a half insert 31 is arranged on the end of the half guide rod 3 close to the back mold plate 1. The half insert 31 is slidably arranged between the half guide rod 3 and the half insert 31, and is slidably connected with the front mold plate 2 through a guide rail. The sliding direction of the half insert 31 is parallel to the length direction of the half guide rod 3. A half separation spring 32 is arranged between the half guide rod 3 and the half insert 31 to serve as a driving force for separating the half insert 31 from the product.
[0032] Referring to Figure 1 The time-delay sliding seat 4 is slidably connected with the front mold plate 2, and the sliding direction of the time-delay sliding seat 4 is the vertical direction. The time-delay sliding seat 4 is fixedly provided with a line position guide rod 41 which is also in the shape of a cylinder and is obliquely arranged. The line position insert 42 is slidably arranged on the upper side of the back mold plate 1, and the sliding direction of the line position insert 42 is the horizontal direction. The line position insert 42 is slidably penetrated by the line position guide rod 41 to realize the horizontal movement of the line position insert 42 through the vertical movement of the line position guide rod 41. The time-delay limiting assembly 5 is arranged on the front mold plate 2 and connected with the time-delay sliding seat 4. Before the time-delay sliding seat 4 slides a predetermined stroke relative to the front mold plate 2, the time-delay sliding seat 4 still slides relative to the front mold plate 2. After the time-delay sliding seat 4 slides the predetermined stroke relative to the front mold plate 2, the time-delay sliding seat 4 cannot slide relative to the front mold plate 2 any more, that is, the time-delay sliding seat 4 and the front mold plate 2 are relatively static.
[0033] Referring to Figure 1, the working principle is as follows, when the front template 2 is separated from the rear template 1, under the action of the half separation spring 32, the half insert 31 makes an inclined movement away from the front template 2, so that the half insert 31 is separated from the workpiece, in this process, the delay slide 4 moves relative to the front template 2, after the relative movement reaches a predetermined value, the row guide rod 41 will move up with the front template 2, so that the row insert 42 is separated from the workpiece, so as to realize the step-by-step separation of the half insert 31 and the row insert 42 from the workpiece, and by adopting this way, the interference between the half insert 31 and the row insert 42 can be avoided, and the half insert 31 and the row insert 42 can move normally, so the mold can be integrated with the half insert 31 and the row insert 42, so that the mold can be prepared for more complex workpieces.
[0034] Referring to Figure 1 , in order to realize the compatibility of the half insert 31 and the row insert 42, the key is to let the half insert 31 separate the workpiece first, and then let the row insert 42 separate the workpiece, by doing so, not only the problem of possible movement interference between the half insert 31 and the row insert 42 is considered, but also the problem of product stress release during demolding is considered, because the half block is separated, the overall stress of the product is released, at this time, the influence of the row core-pulling on the product is the smallest, which can avoid cracks or fractures caused by stress concentration, for example, the problem of demolding force distribution is also considered, for example, during separation, the half block bears the main demolding force, and the row core-pulling only needs to overcome the friction force of the local undercut, if the sequence is reversed, the row needs to bear greater demolding force, which may cause overload or damage of the driving mechanism.
[0035] Referring to Figure 1 and Figure 2 , considering that the half insert 31 separates the workpiece first, the demolding force required for separation is relatively large, therefore, in order to enable the half insert 31 to separate smoothly, the following settings are made, the upper side of the rear template 1 is fixedly installed with a driving pull block 11, the driving pull block 11 is L-shaped and bent, the bent inner side of the driving pull block 11 is away from the direction of the workpiece, and the side of the half insert 31 close to the rear template 1 is also installed with a driven pull block 33, the driven pull block 33 is also L-shaped and bent, the bent inner side of the driven pull block 33 faces the direction of the workpiece, and the driven pull block 33 is hooked and matched with the driving pull block 11, in this way, when the front template 2 is just separated from the rear template 1, a greater initial force can be applied between the driving pull block 11 and the driven pull block 33 through the rigid matching therebetween, so that the half insert 31 is separated from the workpiece, thereby improving the demolding smoothness of the half insert 31.
[0036] Referring to Figure 1 and Figure 3Because of the different shape configurations of the workpiece, the distribution between the half insert 31 and the row insert 42 is different, such as the number ratio between the half insert 31 and the row insert 42 is different, and such as the number of the half insert 31 and the row insert 42 in each of the four sides is different, in summary, the half insert 31 or the row insert 42 needs to be selected according to the shape configuration of different areas on the workpiece, so in order to facilitate the quick assembly of different molds to adapt to different working parameters, the following settings are correspondingly provided, the half separation spring 32 is sleeved on the half guide rod 3, one end of the half separation spring 32 is fixedly connected with the half guide rod 3, and the other end of the half separation spring 32 abuts against the half insert 31, so that the half separation spring 32 and the half guide rod 3 can be realized in one step during assembly, so that one half guide rod 3 and one half separation spring 32 form a half working group, and one delay slide 4, one row guide rod 41 and one delay limiting assembly 5 form a row working group, and the front template 2 is detachably provided with a unit mounting frame 21, one unit mounting frame 21 is provided for mounting and setting one half working group or one row working group, and in summary, according to the different shape configurations of the workpiece, the half working group or the row working group is installed at different positions of the front template 2, so that a mold with different requirements is made at a lower cost.
[0037] Referring to Figure 1 and Figure 3 , considering that the matching configurations between different row inserts 42 and workpieces are different, the working intervals between different row inserts 42 and half inserts 31 are different, that is, the predetermined stroke of the delay slide 4 relative to the front template 2 is changed according to requirements, so the delay limiting assembly 5 includes a limiting block 51, a position adjusting magnet 52 and a balance spring 53, the limiting block 51 is slidably connected to the unit mounting frame 21, the sliding direction of the limiting block 51 is parallel to the sliding direction of the delay slide 4, and the limiting block 51 abuts against the side of the delay slide 4 close to the rear template 1; the position adjusting magnet 52 is fixedly installed on the unit mounting frame 21, the position adjusting magnet 52 is in the form of an electromagnet, the position adjusting magnet 52 drives the limiting block 51 through magnetic field absorption, the position adjusting magnet 52 is located above the limiting block 51, and the position adjusting magnet 52 attracts the limiting block 51 to move upward; the balance spring 53 is connected to the unit mounting frame 21 and the limiting block 51 respectively, so as to balance the magnetic field force applied to the limiting block 51 by the position adjusting magnet 52 through the spring itself, and in summary, the position of the limiting block 51 can be changed under the cooperation of the position adjusting magnet 52 and the balance spring 53, so as to change the maximum stroke of the delay slide 4 relative to the front template 2.
[0038] Referring to Figure 1 and Figure 3, according to the different structures of the workpiece, the distribution modes of the half inserts 31 and the line inserts 42 are also different. For example, for the sake of description, taking the structure of the workpiece having four sides as an example, the number of inserts is different, some are four, some are three, and some are five. Alternatively, the ratio between the half inserts 31 and the line inserts 42 is different, some are one to two, and some are one to three. In order to adapt to such changes, the following settings are correspondingly provided. The lower side of the front template 2 is provided with four adaptive guide rails 22, which are distributed in a rectangular shape around the mold cavity. Meanwhile, the adaptive seats 6 are arranged between the unit mounting frames 21 and the adaptive guide rails 22. Specifically, one unit mounting frame 21 is connected with one adaptive seat 6. The adaptive seat 6 and the adaptive guide rail 22 are in a T-shaped sliding seat sliding rail structure. That is, the adaptive seat 6 can be detached from the end of the length direction of the adaptive guide rail 22. The adaptive seat 6 is screw-mounted with a locking bolt 611. The rod portion of the locking bolt 611 is screw-threaded through the adaptive seat 6. The end surface of the rod portion of the locking bolt 611 also abuts against the side surface of the adaptive guide rail 22, so as to lock the adaptive seat 6 on the adaptive guide rail 22 by friction, thereby freely changing the positions of the half working group and the line working group to adapt to different processing requirements.
[0039] Referring to Figure 1 and Figure 3 , considering that the shape of the workpiece is not necessarily close to a standard cuboid, it may appear that a certain place is relatively thin. Here, thin refers to the width in the horizontal direction being relatively small. The smaller the width, the closer the distance between the line insert 42 and the other line insert 42 or the half insert 31. Therefore, in order to adapt to such changes, the following settings are correspondingly provided. Each adaptive seat 6 is divided into a first seat portion 61 and a second seat portion 62. The first seat portion 61 is slidingly sleeved on the adaptive guide rail 22. The second seat portion 62 is slidingly connected with the first seat portion 61 through a guide rail. The sliding direction of the second seat portion 62 is the horizontal direction. However, the movement direction of the second seat portion 62 is perpendicular to the length direction of the adaptive guide rail 22 to which the adaptive seat 6 is connected. In this way, the second seat portion 62 can move closer to or away from the mold cavity. The second seat portion 62 is also connected with the unit mounting frame 21. Meanwhile, the first seat portion 61 is screw-threaded with a positioning bolt 612. The rod portion of the positioning bolt 612 is rotatably threaded through the second seat portion 62 through a bearing. Therefore, rotating the positioning bolt 612 can change the length of the part of the positioning bolt 612 exposed outside the first seat portion 61 and close to one side of the second seat portion 62. The greater the length, the greater the distance between the second seat portion 62 and the first seat portion 61. Conversely, the smaller the length, the smaller the distance. Therefore, the relative position between the second seat portion 62 and the first seat portion 61 can be changed. In this way, the distance between the half working group or the line working group and the center of the workpiece can be changed, thereby improving the adaptability of the mold.
[0040] Referring to Figure 1 andFigure 4 If the outer wall of some products has a bevel or a bevel hole, a row needle 43 is needed. The row needle 43 is slidably connected to the row insert 42. The movement direction of the row needle 43 is in the same plane as the movement direction of the row insert 42 but intersects. The sliding of the row needle 43 is not completely free of resistance, but has resistance, that is, the row insert 42 will not slide randomly without external force. At the same time, the cooperative driving assembly 7 is arranged between the half insert 31 and the row needle 43. The half insert 31 is preferably the one closest to the row insert 42 where the row needle 43 is located. The cooperative driving assembly 7 has two states. In the connected state, the moving half insert 31 can drive the row needle 43. In the separated state, the half insert 31 and the row needle 43 are not connected. Here, the connection-free includes no direct rigid connection and indirect connection, such as connection through magnetic field or airflow. In summary, the half insert 31 can drive the row needle 43 to separate from the product, and after separation, the front template 2 and the rear template 1 can be normally separated to facilitate the staff to normally take out the product.
[0041] Referring to Figure 1 and Figure 4 Due to different structures of the bevel or bevel hole, the inclination angle of the matched row needle 43 is different, or the demolding stroke of the row needle 43 is different, so in order to adapt to such changes, the cooperative driving assembly 7 includes a supplementary rod 71, a booster spring 72, a transmission piece 73, a horizontal moving plate 74, a transmission magnet 75, a distance adjusting plate 76, a guide magnet 77 and a guide piece 78. The supplementary rod 71 is slidably connected with the half insert 31. The supplementary rod 71 is inclined to slide, and the lower end of the supplementary rod 71 is exposed outside the lower surface of the half insert 31. The booster spring 72 is connected with the half insert 31 and the supplementary rod 71 respectively. The elastic force of the booster spring 72 drives the supplementary rod 71 to move relative to the half insert 31 towards the rear template 1. The transmission piece 73 is fixedly connected to the lower end of the supplementary rod 71. Specifically, the transmission piece 73 can be made of iron, and the transmission piece 73 is connected to the lower end of the supplementary rod 71 in a wrapping manner. The horizontal moving plate 74 is slidably arranged on the rear template 1. The movement direction of the horizontal moving plate 74 is parallel to the movement direction of the row insert 42. In other embodiments, if the movement stroke of the row insert 42 is relatively long, the horizontal moving plate 74 can be embedded and installed on the rear template 1, so that the horizontal moving plate 74 does not protrude from the upper surface of the rear template 1, to avoid movement interference between the horizontal moving plate 74 and the row insert 42.
[0042] Referring to Figure 1 and Figure 4The transmission magnet 75 is arranged on the horizontal moving plate 74, and the transmission magnet 75 is magnetically connected with the transmission sheet 73. Specifically, the transmission magnet 75 and the transmission sheet 73 abut together. The distance adjusting plate 76 is hingedly connected with the horizontal moving plate 74. Specifically, a damping rotating shaft is used to realize the connection. Then, the distance adjusting plate 76 can be rotated to change the distance between the upper end of the distance adjusting plate 76 and the row position insert pin 43, so as to adapt to the row position insert pin 43 in different installation positions. The guide magnet 77 is fixedly arranged on the upper end of the distance adjusting plate 76. The guide sheet 78 is connected on the lower side of the row position insert pin 43. The guide sheet 78 is gap-magnetically connected with the guide magnet 77, that is, the guide magnet 77 and the guide sheet 78 do not abut together. At the same time, the magnetic attraction force of the guide magnet 77 to the guide sheet 78 can overcome the damping force between the row position insert pin 43 and the row position insert piece 42. In this way, the purpose of moving the row position insert pin 43 by the horizontal moving plate 74 without direct connection is realized.
[0043] With reference to Figure 1 and Figure 4 , the working process is as follows. When the front mold plate 2 and the rear mold plate 1 are separated, the half insert piece 31 moves relative to the front mold plate 2 to approach the rear mold plate 1. At this time, the half insert piece 31 also abuts against the rear mold plate 1. At the same time, the half insert piece 31 is away from the workpiece. Then, the transmission sheet 73 moves away from the workpiece, so that the horizontal moving plate 74 slides away from the workpiece. In this process, the guide magnet 77 on the distance adjusting plate 76 gap-magnetically attracts the guide sheet 78 to make the row position insert pin 43 out of the workpiece. After the half insert piece 31 and the rear mold plate 1 are separated, the movement of the half insert piece 31 relative to the front mold plate 2 is completed. However, the supplemental rod 71 can continue to move outward under the action of the assisting spring 72, so as to adapt to the row position insert pin 43 with different demolding strokes.
[0044] In addition, considering that the demolding strokes of different row position insert pins 43 are different, the part of the row position insert pin 43 penetrating through the row position insert piece 42 is in a stepped shaft structure, and the part of the row position insert piece 42 matched with the stepped shaft structure is in a stepped hole structure. Through the cooperation between the stepped shaft structure and the stepped hole structure, the movement of the row position insert pin 43 which first reaches the demolding stroke in the direction away from the workpiece is limited. The advantage is that the cooperation between the guide magnet 77 and the guide sheet 78 only provides power for the movement of the row position insert pin 43, and the row position insert pin 43 will not move too far.
[0045] With reference to Figure 1 and Figure 4Since the demolding strokes of the different row-position insert pins 43 are different, in order to separate the front mold plate 2 and the rear mold plate 1 by a predetermined distance, all the row-position insert pins 43 need to be separated, which requires corresponding changes in the inclination angle of the supplementary rod 71 matched with the row-position insert pins 43. Meanwhile, if the demolding strokes of the multiple row-position insert pins 43 are the same, but if the multiple row-position insert pins 42 need to be separated in sequence, the inclination angle of the supplementary rod 71 matched with the row-position insert pins 42 also needs to be changed. Based on the above, the connecting rotating seat 8 and the connecting guide pipe 81 are arranged between the supplementary rod 71 and the half insert 31. The connecting rotating seat 8 is rotationally connected with the half insert 31. Specifically, a damping rotating shaft can be used to realize the rotational connection, or a bolt rotating shaft or other structures can be selected, as long as the connecting rotating seat 8 can rotate and stop in different postures. The connecting guide pipe 81 is used for the sliding connection of the supplementary rod 71, so that the inclination angle of the supplementary rod 71 can be changed through the connecting rotating seat 8.
[0046] The implementation principle of the injection mold with the composite lateral slider mechanism in the embodiment of the present application is as follows: when the front mold plate 2 and the rear mold plate 1 are separated, the half insert 31 makes an inclined movement away from the front mold plate 2 under the action of the half separation spring 32, so that the half insert 31 is separated from the product. In this process, the delay sliding seat 4 moves relative to the front mold plate 2. When the relative movement stroke reaches a predetermined value, the row-position guide rod 41 moves upward with the front mold plate 2, so that the row-position insert pin 42 is separated from the product. In summary, the delay separation is adopted, which can avoid the interference between the half insert 31 and the row-position insert pin 42, and make the half insert 31 and the row-position insert pin 42 move smoothly. Therefore, the mold can be integrated with the half insert 31 and the row-position insert pin 42, so that the mold can be used to prepare more complex products.
[0047] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape, and principle of the present application should be covered by the protection scope of the present application.
