Abstract
Description
Technical Field
[0001] This application belongs to the field of molds. More specifically, it relates to a demolding assembly and a mold. Background Art
[0002] A mold is a tool for producing plastic products and is also a tool for giving plastic products a complete structure and precise dimensions.

[0003] After the injection molding of an injection-molded product is completed, it is necessary to demold the slider inserts in each slider mechanism from the product. In the prior art, a driving mechanism needs to be installed for each slider mechanism respectively, and then the corresponding slider mechanism is driven to move by each driving mechanism to complete the mold opening and closing operations. Setting multiple driving mechanisms makes the overall mechanism of the mold complex and the cost too high. Summary of the Invention

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.
[0036] It should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.
[0037] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "a plurality" is two or more unless otherwise specifically defined.
[0038] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0039] Please refer to Figures 1 to 8 together, and now an ejection assembly provided by an embodiment of the present application will be described. The ejection assembly includes a first slider mechanism 10, a second slider mechanism 20, and a driving mechanism 30.
[0040] The driving mechanism 30 can reciprocate between a first position and a second position. The driving mechanism 30 includes a first diagonal support pin 31 and a second diagonal support pin 32. The first diagonal support pin 31 is slidably connected to the first slider mechanism 10, and the second diagonal support pin 32 is slidably connected to the second slider mechanism 20. Wherein, when the driving mechanism 30 moves from the first position to the second position, the first diagonal support pin 31 can drive the first slider mechanism 10 to move away from the molding station 60, and the second diagonal support pin 32 can drive the second slider mechanism 20 to move away from the molding station 60. When the driving mechanism 30 moves from the second position to the first position, the first diagonal support pin 31 can drive the first slider mechanism 10 to move towards the molding station 60, and the second diagonal support pin 32 can drive the second slider mechanism 20 to move towards the molding station 60.
[0041] For example, as Figures 1 to 8As shown, the first row positioning mechanism 10 and the second row positioning mechanism 20 are used to assist the product in completing the injection molding process. The driving mechanism 30 is mainly used to drive the first row positioning mechanism 10 and the second row positioning mechanism 20 to complete the mold closing and mold opening processes. The driving mechanism 30 can reciprocate between a first position and a second position. Among them, the first position is closer to the first row positioning mechanism 10 and the second row positioning mechanism 20 than the second position. The driving mechanism 30 includes a first diagonal support pin 31 and a second diagonal support pin 32. The first diagonal support pin 31 is slidably connected to the first row positioning mechanism 10, and the second diagonal support pin 32 is slidably connected to the second row positioning mechanism 20. Among them, when the driving mechanism 30 moves from the first position to the second position, the first diagonal support pin 31 can drive the first row positioning mechanism 10 to move away from the molding station 60, and the second diagonal support pin 32 can drive the second row positioning mechanism 20 to move away from the molding station 60, thereby completing the mold opening process. When the driving mechanism 30 moves from the second position to the first position, the first diagonal support pin 31 can drive the first row positioning mechanism 10 to move closer to the molding station 60, and the second diagonal support pin 32 can drive the second row positioning mechanism 20 to move closer to the molding station 60, thereby completing the mold closing process.
[0042] Specifically, the moving direction of the first row positioning mechanism 10 is perpendicular to the moving direction of the driving mechanism 30. For example, as Figure 6 and Figure 7 shown, the driving mechanism 30 can move in a first moving direction or a second moving direction. When the driving mechanism 30 moves in the first moving direction to a position where the first diagonal support pin 31 is disengaged from the first row positioning mechanism 10, it is denoted as the second position. When the driving mechanism 30 moves in the second moving direction to a position where the first diagonal support pin 31 drives the first row positioning mechanism 10 to reach the molding station 60, it is denoted as the first position. The first row positioning mechanism 10 can move in a third moving direction and a fourth moving direction.
[0043] Compared with the prior art, the demolding assembly provided in the present application simplifies the structure of the demolding assembly and reduces production costs by providing a first diagonal support pin 31 and a second diagonal support pin 32 in the driving mechanism 30, slidably connecting the first diagonal support pin 31 to the first row positioning mechanism 10, and slidably connecting the second diagonal support pin 32 to the second row positioning mechanism 20. During the reciprocating movement of the first diagonal support pin 31 and the second diagonal support pin 32 in the driving mechanism 30 between the first position and the second position, the first diagonal support pin 31 and the second diagonal support pin 32 respectively drive the first row positioning mechanism 10 and the second row positioning mechanism 20 to complete the mold closing and mold opening processes. The driving mechanism 30 can drive the first row positioning mechanism 10 and the second row positioning mechanism 20 to move respectively, without separately providing independent driving mechanisms 30 in the first row positioning mechanism 10 and the second row positioning mechanism 20.
[0044] In an embodiment of the present application, please refer toFigures 2 to 8 , the first row positioning mechanism 10 includes a first row positioning seat 12. The first row positioning seat 12 is provided with a first connection hole 101. The first diagonal support pin 31 is inserted into the first connection hole 101. The hole wall of the first connection hole 101 has a first abutting side 102 and a second abutting side 103. The first abutting side 102 and the second abutting side 103 are sequentially distributed in a direction away from the forming station 60; the second row positioning mechanism 20 includes a second row positioning seat 22. The second row positioning seat 22 is provided with a second connection hole 201. The second diagonal support pin 32 is inserted into the second connection hole 201. The hole wall of the second connection hole 201 has a third abutting side 203 and a fourth abutting side 204. The third abutting side 203 and the fourth abutting side 204 are sequentially distributed in a direction away from the forming station 60; when the first diagonal support pin 31 abuts against the first abutting side 102 and the second diagonal support pin 32 abuts against the third abutting side 203, the distance between the second abutting side 103 and the first diagonal support pin 31 is greater than the distance between the fourth abutting side 204 and the second diagonal support pin 32.
[0045] Specifically, the extending direction of the first connection hole 101 is consistent with the extending direction of the first diagonal support pin 31. The first diagonal support pin 31 has a cylindrical structure. The outer peripheral wall of the first diagonal support pin 31 has a clearance fit with the hole wall of the first connection hole 101. When the first diagonal support pin 31 is in the first position, the first diagonal support pin 31 abuts against the first abutting side 102. When the first diagonal support pin 31 is in the second position, the first diagonal support pin 31 abuts against the second abutting side 103. Thus, during the process of the first diagonal support pin 31 moving from the first position to the second position, the first diagonal support pin 31 needs to move from the first abutting side 102 to the second abutting side 103. During this process, the first row positioning mechanism 10 does not displace. Only after the first diagonal support pin 31 abuts against the second abutting side 103 does it start to drive the first row positioning mechanism 10 to move towards the side away from the forming station 60. At the same time, there is also a clearance fit between the second diagonal support pin 32 and the second connection hole 201. The clearance between the second diagonal support pin 32 and the second connection hole 201 is only used for the second diagonal support pin 32 and the second row positioning seat 22 to be able to relatively slide in the natural state. Therefore, without considering friction, when the second diagonal support pin 32 moves from the first position to the second position, the outer peripheral wall of the second diagonal support pin 32 always abuts against the third abutting side 203 and the fourth abutting side 204. So during the actual operation of the demolding assembly, the second diagonal support pin 32 in the driving mechanism 30 will first drive the second row positioning mechanism 20 to move a certain distance in the direction away from the forming station 60, and then the first diagonal support pin 31 drives the first row positioning mechanism 10 to move in the direction away from the forming station 60, thereby controlling the movement sequence of the first row positioning mechanism 10 and the second row positioning mechanism 20 through a single driving mechanism 30 and avoiding movement interference between the first row positioning mechanism 10 and the second row positioning mechanism 20.
[0046] It can be understood that the staff can adjust the relative movement distance between the first row position mechanism 10 and the second row position mechanism 20 by changing the shape of the first connection hole 101 through the hole.
[0047] In an embodiment of the present application, please refer to Figure 2 and Figure 4 , the second row position seat 22 is slidably installed on the first row position seat 12; a first limiting portion 13 is provided on the first row position seat 12, a first limiting groove 221 is provided in the second row position seat 22, and the first limiting portion 13 is engaged in the first limiting groove 221; alternatively, a first limiting groove 221 is provided on the first row position seat 12, a first limiting portion 13 is provided on the second row position seat 22, and the first limiting portion 13 is engaged in the first limiting groove 221.
[0048] Specifically, the first limiting portion 13 protrudes from the side of the first row position seat 12 close to the second row position seat 22, and the first limiting groove 221 is opened on the side of the second row position seat 22 close to the first row position seat 12. When the second row position seat 22 slides to the position of the mold opening process, the first limiting portion 13 is engaged in the first limiting groove 221 to prevent the second row position seat 22 from sliding randomly on the first row position seat 12.
[0049] In an embodiment of the present application, please refer to Figure 2 , Figure 5 and Figure 8 , the demolding assembly further includes an elastic member 23, the elastic member 23 abuts between the first row position mechanism 10 and the second row position mechanism 20, and the elastic deformation direction of the elastic member 23 is parallel to the moving direction of the first row position mechanism 10.
[0050] Specifically, when the driving mechanism 30 is in the first position, the elastic member 23 is in a compressed state. At this time, since the first row position mechanism 10 abuts on the molding station 60 and cannot move further in the direction close to the molding station 60, the restoring elastic force of the elastic member 23 acts on the second row position mechanism 20. By providing the elastic member 23 between the first row position mechanism 10 and the second row position mechanism 20, it can cooperate with the second inclined strut pin 32 to drive the second row position mechanism 20 to move away from the molding station 60.
[0051] Specifically, the elastic member 23 can be a spring, a rubber elastic block or other elastic components.
[0052] In an embodiment of the present application, please refer to Figure 2 , Figure 4 , Figure 6 and Figure 8, the first row positioning mechanism 10 further includes a first row positioning insert 11, the first row positioning insert 11 is connected to the first row positioning seat 12, the second row positioning mechanism 20 further includes a second row positioning insert 21, the first row positioning insert 11 is provided with a mounting hole 111, the second row positioning insert 21 is disposed in the mounting hole 111, the second row positioning insert 21 can slide along the extending direction of the mounting hole 111, a sliding groove 122 communicating with the mounting hole 111 is provided in the first row positioning insert 11, the second row positioning seat 22 is slidably mounted in the sliding groove 122, the second row positioning seat 22 can reciprocally slide along the extending direction of the sliding groove 122, and the second row positioning seat 22 abuts against the second row positioning insert 21 to drive the second row positioning insert 21 to approach or move away from the molding station 60 along the extending direction of the mounting hole 111.
[0053] Specifically, the second row positioning mechanism 20 is disposed on the first row positioning mechanism 10, the second inclined strut pin 32 can drive the second row positioning mechanism 20 to move relative to the first row positioning mechanism 10 in the first row positioning mechanism 10. In this embodiment, the second row positioning insert 21 can slide in the mounting hole 111 to a position close to or away from the molding station 60, and the second row positioning seat 22 can slide along the extending direction of the sliding groove 122 to a position close to or away from the molding station 60. When the second row positioning mechanism 20 performs the mold closing process, the second row positioning seat 22 moves in the direction close to the molding station 60 driven by the driving mechanism 30, and then the second row positioning seat 22 drives the second row positioning insert 21 to move to the molding station 60 along the extending direction of the mounting hole 111 to complete the mold closing process. When the second row positioning mechanism 20 performs the mold opening process, the second row positioning seat 22 moves in the direction away from the molding station 60 driven by the driving mechanism 30, and then the second row positioning seat 22 drives the second row positioning insert 21 to move away from the molding station 60 along the extending direction of the mounting hole 111 to complete the mold opening process. By disposing the second row positioning mechanism 20 on the first row positioning mechanism 10, the volume of the entire demolding assembly can be significantly reduced, and the space occupied by the entire structure can be decreased.
[0054] Specifically, the staff can change the angle of the second row positioning insert 21 in the molding station 60 by changing the extending direction of the mounting hole 111 according to the actual outer shape requirements of different products. In this embodiment, the sliding direction of the first row positioning insert 11 is different from the sliding direction of the second row positioning insert 21, so that the injection-molded product has structural features in two different directions.
[0055] In an embodiment of the present application, a transmission inclined surface is provided on one side of the second row positioning seat 22 close to the second row positioning insert 21, and the second row positioning insert 21 abuts against the transmission inclined surface.
[0056] Specifically, the transmission inclined surface is inclined toward the side of the mounting hole 111. The sliding direction of the second slide insert 21 in the mounting hole 111 is different from the sliding direction of the second slide base 22 in the sliding groove 122. By providing the transmission inclined surface in the mounting hole 111, when the second slide base 22 slides to a position close to the molding station 60, the second slide insert 21 slides along the transmission inclined surface, so as to drive the second slide insert 21 to slide along the extension direction of the mounting hole 111 to a position close to the molding station 60.
[0057] Specifically, the second slide base 22 includes a base body and a connecting member. The base body and the connecting member are connected together by a fastener. The second inclined strut pin 32 is slidably connected to the base body. A dovetail groove structure is adopted between the connecting member and the second slide insert 21 for sliding connection. By setting the sliding connection structure between the second slide insert 21 and the second slide base 22 as a dovetail groove structure, the second slide insert 21 and the second slide base 22 can not only maintain the sliding connection state but also maintain the mutual connection relationship, avoiding their separation from each other and ensuring the stability of the second slide insert 21 during the mold closing and mold opening processes.
[0058] In an embodiment of the present application, please refer to Figure 4 together. An introduction groove 202 is recessed on the inner wall surface at one end of the second connection hole 201 facing away from the first slide base 12.
[0059] Specifically, the extension direction of the second connection hole 201 is the same as the extension direction of the second inclined strut pin 32. The introduction groove 202 is provided on the side of the second connection hole 201 facing away from the first slide base 12, and the introduction groove 202 is recessed on the inner wall surface at one end of the second connection hole 201 close to the second slide insert 21. By providing the introduction groove 202 in the second connection hole 201, during the process of the driving mechanism 30 moving from the second position to the first position, the second inclined strut pin 32 can be inserted into the second connection hole 201 along the introduction groove 202, avoiding interference between the second inclined strut pin 32 and the second slide base 22 and ensuring that the second inclined strut pin 32 cannot be smoothly inserted into the second connection hole 201.
[0060] In an embodiment of the present application, please refer to Figure 2 and Figures 4 to 8 together. The demolding assembly further includes a bottom plate 40. The first slide mechanism 10 is slidably mounted on the bottom plate 40. A second limiting portion 41 is provided on one side of the bottom plate 40 close to the first slide mechanism 10. A second limiting groove 121 is provided on the bottom surface of the first slide base 12, and the second limiting portion 41 is engaged in the second limiting groove 121; alternatively, the bottom plate 40 is provided with a second limiting groove 121, and the bottom surface of the first slide base 12 is provided with a second limiting portion 41, and the second limiting portion 41 is engaged in the second limiting groove 121.
[0061] Specifically, two second limit grooves 121 are provided on the bottom surface of the first slide mechanism 10, and the two second limit grooves 121 are arranged in sequence along the sliding direction of the first slide seat 12. When the first slide seat 12 moves to the mold closing position, the second limit portion 41 is engaged with the second limit groove 121 away from the molding station 60. When the first slide seat 12 moves to the mold opening position, the second limit portion 41 is engaged with the second limit groove 121 close to the molding station 60.
[0062] Specifically, a mounting groove is provided on the bottom plate 40, and the second limiting portion 41 is arranged in the mounting groove. A spring is also provided in the mounting groove, and one end of the spring abuts against the groove bottom of the mounting groove, and the other end of the spring abuts against the second limiting portion 41. During the sliding process of the first row seat 12, the second limiting portion 41 will be inserted into the corresponding first limiting groove 221 only when the first row seat 12 moves to the mold closing position and the mold opening position. When the first row seat 12 slides between the mold closing position and the mold opening position, the second limiting portion 41 will be compressed back into the mounting groove to ensure that the first row seat 12 slides smoothly on the bottom plate 40.
[0063] In one embodiment of the present application, please refer to Figure 2 , Figures 4 to 8 The driving mechanism 30 also includes a first shovel base 33 and a second shovel base 34. The first shovel base 33 is used to abut against the side of the first slide mechanism 10 away from the forming station 60, and the second shovel base 34 is used to abut against the side of the second slide mechanism 20 away from the forming station 60.
[0064] Specifically, after the mold closing process of the demolding assembly is completed, the first row insert 11 and the second row insert 21 are both located in the molding station 60. At this time, the first shovel base 33 abuts against the side of the first row seat 12 that is away from the molding station 60, and the second shovel base 34 abuts against the side of the second row seat 22 that is away from the molding station 60. Therefore, during the product molding process, the first shovel base 33 and the second shovel base 34 can withstand the pressure generated by the injection molding on the first row insert 11 and the second row insert 21, thereby preventing the pressure of the injection molding from forcing the first row mechanism 10 and the second row mechanism 20 to move in a direction away from the molding station 60, thereby ensuring the stability of the molding process.
[0065] Specifically, Figure 4 and Figure 6As shown, the second shovel base 34 is provided with a first avoidance groove 341, and the second row seat 22 is provided with a second avoidance groove 222. The first avoidance groove 341 and the second avoidance groove 222 are adapted to each other. When the driving mechanism 30 moves from the second position to the first position, there is a risk that the end of the second shovel base 34 close to the second row seat 22 will collide with the second row seat 22. By providing the first avoidance groove 341 on the second shovel base 34 and the second avoidance groove 222 on the second row seat 22, it is possible to avoid collision between the two due to errors in the process of the second shovel base 34 approaching the second row seat 22.
[0066] Specifically, the demolding assembly also includes a backhoe 50, which is fixedly arranged in the demolding assembly. When the driving mechanism 30 is located in the first position, the side of the first shovel base 33 facing away from the second shovel base 34 abuts against the backhoe 50, thereby preventing the first sliding mechanism 10 and the second sliding mechanism 20 from continuing to move in the direction away from the molding station 60.
[0067] The present application also provides a mold, which includes the demoulding component in any one of the above embodiments, and thus has at least all the beneficial effects of the demoulding component in the above embodiments, which will not be described one by one here.
[0068] The mold provided in the present application adopts the demolding assembly in the above-mentioned embodiment to greatly reduce the size of the mold. At the same time, no external signal is required to control the movement sequence of the first sliding mechanism 10 and the second sliding mechanism 20, thereby avoiding the risk of movement interference between the first sliding mechanism 10 and the second sliding mechanism 20.
[0069] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for explaining the principles of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementations of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
