Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection molds, and in particular to a mold anti-overflow glue mechanism. Background Technology
[0002] Injection molds are widely used due to their high precision and high quality. However, during the injection of adhesive into the mold, structural gaps in the mold itself can cause adhesive overflow within the molding cavity. This overflow results in an incomplete product surface, requiring manual repair, which increases processing costs. Furthermore, it makes it impossible to ensure that the product surface smoothness and integrity meet requirements, reducing processing efficiency.
[0003] Therefore, based on the above reasons, how to design a structure that can effectively prevent mold overflow is one of the technical problems that need to be solved by those skilled in the art. Utility Model Content
[0004] To address the technical problems existing in the prior art, the purpose of this utility model is to provide an injection mold with an elastic inclined top.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A mold anti-overflow glue mechanism includes a cylinder, a threaded rod, a cylinder connecting rod, a sealing ring, and a plastic filling part, wherein:
[0007] The cylinder connecting rod has an inner hole, and a threaded rod is installed on the bottom surface of the inner hole. The threaded rod is hidden in the inner hole, and the sealing ring is fitted on the side wall of the inner hole.
[0008] The plastic filling part is fitted onto the outside of the cylinder connecting rod, forming a structure that clamps and seals the cylinder connecting rod.
[0009] A positioning hole is provided at one end of the cylinder;
[0010] The cylinder insert, which is driven to move, is inserted into the inner hole, and the threaded rod is inserted into the positioning hole. Due to the insertion of the cylinder insert, the sidewall of the inner hole expands radially, which drives the sealing ring to expand. The expanded sealing ring fits tightly with the filling plastic to form an anti-overflow mechanism.
[0011] A further preferred embodiment: the cylinder connecting rod has a plug-in end, and an inner concave hole is formed from the plug-in end along the axial direction of the cylinder connecting rod, the inner concave hole being the inner hole;
[0012] The cylinder connecting rod has a sealing ring at its insertion end for fitting the sealing ring.
[0013] A further preferred embodiment: the outer diameter of the cylinder connecting rod gradually decreases from the insertion end along its axial direction to the other end;
[0014] The insertion end of the cylinder connecting rod is the end with the maximum outer diameter of the cylinder connecting rod.
[0015] A further preferred embodiment: the outer surface of the insertion end of the cylinder connecting rod is in contact with the inner wall of the plastic filling part.
[0016] A further preferred embodiment: the filling plastic part is provided with a positioning ring, which is a thin-walled ring, and the positioning ring is provided corresponding to the sealing ring.
[0017] A further preferred embodiment: the bottom surface of the inner bore of the cylinder connecting rod is provided with a threaded hole along its axial direction for assembling the threaded rod.
[0018] A further preferred embodiment: the cylinder insert is driven by the cylinder to move along its axial direction to engage with the cylinder connecting rod.
[0019] A further preferred embodiment: the cylinder separator is connected to the cylinder via a connecting rod and operates in conjunction with it.
[0020] A further preferred embodiment: a sliding core is fitted onto the outer side of the cylinder housing;
[0021] The sealing ring is clamped between the sliding core, the plastic filling part, and the cylinder connecting rod.
[0022] By adopting the above technical solution, this utility model has the following advantages compared with the prior art:
[0023] The technical solution disclosed in this utility model utilizes the insertion of a cylinder core and a cylinder connecting rod, thereby expanding the sealing ring using the expanding cylinder connecting rod. Since the sealing ring is placed between the cylinder connecting rod and the plastic part being filled, the expanded sealing ring fits tightly with the plastic part being filled, thereby improving the sealing performance and preventing glue overflow from occurring in the product molding cavity during glue filling. This ensures that the product surface is smooth and intact, improves product quality, achieves the purpose of one-time injection molding, eliminates correction processes, and reduces costs.

[0039] Example
[0040] like Figure 1 and Figure 2As shown, this utility model discloses a mold anti-overflow glue mechanism, which utilizes a cylinder connector 130 and a cylinder connecting rod 150 for insertion. The expanding cylinder connecting rod 150 expands the sealing ring 200. Since the sealing ring 200 is placed between the cylinder connecting rod 150 and the plastic part being filled, the expanded sealing ring 200 fits tightly with the plastic part being filled, thereby improving the sealing performance and preventing glue overflow in the product molding cavity during glue filling. This ensures that the product surface is smooth and intact, improves product quality, achieves the purpose of one-time injection molding, eliminates correction processes, and reduces costs.
[0041] like Figure 1 , Figure 2 Right now Figure 3 As shown, the mold anti-overflow glue mechanism includes a cylinder insert 130, a cylinder connecting rod 150, a filling plastic 160, and a sealing ring 200. The cylinder insert 130 passes through the sliding core 140. The cylinder connecting rod 150 is fitted with the filling plastic 160 on its side wall and has an inner hole along its axial direction. The cylinder insert 130, driven to move in the direction of the cylinder connecting rod 150, is inserted into the inner hole of the cylinder connecting rod 150. At the same time, the threaded rod 170 fixed on the cylinder connecting rod 150 is inserted into the cylinder insert 130. Due to the insertion of the cylinder insert 130, the side wall of the inner hole of the cylinder connecting rod 150 expands outward along its radial direction to increase the outer diameter of the cylinder connecting rod 150 near the cylinder insert 130. A sealing ring 200 is fitted at the corresponding expansion part of the cylinder connecting rod 150, and the sealing ring 200 also expands outward synchronously, so that the filling plastic 160 fits tightly. It should be noted that: the sealing ring 200 is fitted on the outer side of the cylinder connecting rod 150 near the cylinder insert 130, the filling plastic part abuts against the outer side of the sealing ring 200, and the sealing ring 200, driven by the cylinder connecting rod 150 to expand outward, abuts against the filling plastic 160, so that the sealing ring 200 and the inner wall of the filling plastic 160 are firmly adhered, thereby achieving the purpose of preventing glue overflow.
[0042] like Figure 1 , Figure 2 Right now Figure 3As shown, the cylinder insert 130 is a thin rod with one end as a connecting end and the other end as a linkage end along its axial direction. The connecting end of the cylinder 110 is used to connect with the cylinder 110 to achieve displacement by driving the cylinder 110. The linkage end has an expansion hole. Preferably, in order to better achieve the purpose of expanding the outer diameter of the cylinder connecting rod 150, the outer diameter of the linkage end of the cylinder insert 130 gradually decreases. More specifically, the end of the linkage end that extends into the inner hole of the cylinder 110 linkage rod is an insertion section. The outer diameter of this insertion section gradually decreases from the connecting end side to the linkage end side. That is to say, the outer diameter of the linkage end is the minimum size. Thus, as the linkage end of the cylinder insert 130 is inserted into the inner hole of the cylinder connecting rod 150, it drives the sidewall of the inner hole to expand outward.
[0043] like Figure 1 , Figure 2 Right now Figure 3 As shown, the connecting end of the cylinder insert 130 is connected to the cylinder 110 via a connecting rod. Specifically, the connecting rod is a rod with a diameter larger than that of the cylinder insert 130. One end of the connecting rod is connected to and linked with the output end of the cylinder 110, and the other end has a connecting hole. The connecting end of the cylinder insert 130 is inserted into the connecting hole and engaged, thereby connecting and linking the cylinder insert 130 with the cylinder 110. The linkage end of the cylinder insert 130 has an expansion hole along its axial direction. The cylinder connecting rod 150 has the aforementioned inner hole at one end facing the cylinder insert 130, and the bottom surface of the inner hole has a threaded hole along its axial direction for connecting the threaded rod 170.
[0044] like Figure 1 , Figure 2 Right now Figure 3 As shown, the outer diameter of the threaded rod 170 is smaller than that of the cylinder connector 130. It is threadedly connected to the threaded hole of the cylinder connecting rod 150. In the injection mold structure, the cylinder connecting rod 150 is fixedly installed. Therefore, the threaded rod 170, which is threadedly connected to the cylinder connecting rod 150, is also fixedly installed. That is, when the cylinder 110 drives the cylinder insert 130 to move toward the cylinder connecting rod 150 via the connecting rod, the linkage end of the cylinder insert 130 is inserted into the inner hole of the cylinder connecting rod 150. At the same time, the threaded rod 170, which is fixed in the inner cavity of the inner hole, is inserted into the expansion hole of the cylinder insert 130. The threaded rod 170 is inserted into the expansion hole of the cylinder insert 130, causing the side wall of the expansion hole to expand outward. The side wall of the expansion hole fits against the side wall of the inner hole of the cylinder connecting rod 150 and simultaneously abuts against the side wall of the inner hole, and simultaneously drives the side wall of the inner hole to expand outward along its radial direction.
[0045] like Figure 1 , Figure 2 Right now Figure 3 As shown, the threaded rod 170 can expand the sidewall of the inner hole, and can also achieve precise insertion while the cylinder insert 130 is driven to move. At the same time, the cooperation between the threaded rod 170 and the expansion hole can also achieve precise positioning of the cylinder insert 130.
[0046] Specifically: such as Figure 1 , Figure 2 Right now Figure 3 As shown, the cylinder connecting rod 150 is a short rod with one end being a plug-in end, which is the end that mates with the cylinder insert 130. An inner recessed hole is formed along the axial direction of the cylinder connecting rod 150 from the end face of the plug-in end; this inner recessed hole is the inner bore. The outer diameter of the cylinder connecting rod 150 gradually decreases from its plug-in end along its axial direction to the other end. It should be noted that the plug-in end of the cylinder connecting rod 150 has a sealing ring 200. The sealing ring 200 is an annular thin wall formed by the axial extension of the plug-in end of the cylinder connecting rod 150 along the inner side of the inner bore. Obviously, its thickness is small. When the cylinder insert 130 is plugged into the cylinder connecting rod 150, the sealing ring 200 can adhere to the outer surface of the cylinder insert 130. Simultaneously, the aforementioned sealing ring 200 is also assembled at the location of the sealing ring 200. It should be noted that: the sealing ring 200 is fitted onto the cylinder connecting rod 150, and the thickness of the sealing ring 200 is different from that of the cylinder connecting rod 150, resulting in a stepped groove between the sealing ring 200 and the cylinder connecting rod 150. The sealing ring 200 is fitted onto the cylinder connecting rod 150 and is locked in the groove.
[0047] like Figure 1 , Figure 2 Right now Figure 3As shown, the filled plastic 160 is a cylindrical component, hollow and through, fitted onto the outside of the cylinder connecting rod 150. Because the outer diameter of the cylinder connecting rod 150 varies along its axial direction, the gap between the inner wall of the filled plastic 160 and the outer wall of the cylinder connecting rod 150 also varies accordingly. Specifically, one end of the filled plastic 160 facing the cylinder 110 is the first end, and the other end is the second end; the gap gradually decreases from the first end to the second end. It should be noted that the inner diameter of the filled plastic 160 does not change; that is, the inner diameter of the filled plastic 160 is consistent. The first end of the filled plastic abuts against the sealing ring 200, and a structure is formed between one end of the filled plastic 160 and the sealing ring 200 of the cylinder connecting rod 150 to clamp the sealing ring 200. Based on the above structure, when the cylinder insert 130 is driven by the cylinder 110 to be inserted into the inner hole of the cylinder connecting rod 150, the cylinder connecting rod 150 is driven to expand, which in turn drives the sealing ring 200 to expand. The expanded sealing ring 200 can fit tightly against the surface of the filling plastic 160, thereby improving the sealing effect and effectively preventing glue overflow.
[0048] It should be noted that: such as Figure 1 , Figure 2 Right now Figure 3 As shown, a positioning ring is provided at the first end of the filling plastic 160, and a positioning groove is provided on the outer surface of the positioning ring. The positioning groove can be inserted into other parts of the mold to position the filling plastic part. The positioning ring and the sealing ring 200 of the cylinder connecting rod 150 clamp the sealing ring 200.
[0049] like Figure 1 , Figure 2 Right now Figure 3 As shown, a sliding core 140 is also provided on the outside of the cylinder mediator 130. The sliding core 140 is a cylindrical part. The cylinder mediator 130 passes through the sliding core 140. One end of the sliding core 140 abuts against one side of the sealing ring 200. Along the axial direction of the cylinder mediator 130, a structure is formed in which the sealing ring 200 is clamped between the sliding core 140 and the cylinder connecting rod 150. Along the axial direction perpendicular to the cylinder mediator 130, the sealing ring 200 is clamped between the sealing ring 200 of the cylinder connecting rod 150 and the plastic filling part.
[0050] like Figure 1 , Figure 2 Right now Figure 3 As shown, based on the above structure, the working principle of the mold anti-overflow glue mechanism is as follows:
[0051] The cylinder 110 is displaced by connecting to the driving cylinder 130. The driven cylinder 130 moves within the sliding core 140. The linkage end of the cylinder 130 is inserted into the inner hole of the cylinder connecting rod 150. The threaded rod 170, which is placed in the inner hole, is inserted into the linkage end of the cylinder 130. After completing the above actions, the inner hole sidewall of the cylinder connecting rod 150 is expanded. The expanded inner hole sidewall (i.e., the sidewall of the cylinder connecting rod 150) drives the sealing ring 200 to expand outward through the sealing ring 200. That is, the sealing ring 200, which is set between the sliding core 140, the cylinder connecting rod 150, and the plastic filling part, is clamped. The expanded sealing ring 200 is tightly fitted with the inner wall of the plastic filling part 160, thereby improving the sealing effect and effectively preventing glue overflow.
[0052] Combination Figure 4 and Figure 5 As shown, this is a processing method. Figure 6 Product A shown here is an injection mold anti-overflow mechanism applied to an injection mold. The injection mold includes a mold frame, a mold core, and the anti-overflow mechanism. Both the mold core and the anti-overflow mechanism are assembled within the mold frame.
[0053] Combination Figure 4 and Figure 5 As shown, the mold frame includes a fixed mold assembly and a moving mold assembly. The fixed mold assembly includes a fixed mold top plate 410, a fixed mold pad plate 420, and a fixed mold plate 430 arranged and connected in sequence. The fixed mold plate 430 has a mold setting groove facing the moving mold assembly. The moving mold assembly includes a moving mold base plate 510, square irons 520, a moving mold plate 530, and an ejection mechanism. The two square irons 520 are symmetrically distributed and fixed on the base plate. The moving mold plate 530 is fixed on the two square irons 520. The two square irons 520, the moving mold plate 530, and the moving mold base plate 510 enclose an ejection cavity. The ejection plate assembly 540 is placed in the ejection cavity. The ejection mechanism includes the ejection plate assembly 540 and an ejector pin. The ejector pin is fixed on the ejection plate assembly 540. The moving mold plate 530 has a moving mold groove facing the fixed mold assembly.
[0054] Combination Figure 4 and Figure 5 As shown, the mold core includes a fixed mold core 310 and a movable mold core 320. The fixed mold core 310 is fixed in the fixed mold groove of the fixed top mold plate, and the movable mold core 320 is fixed in the movable mold groove of the movable top mold plate. The movable mold core 320 and the fixed mold core 310 form a cylindrical cavity that is adapted to the shape structure of product A. The fixed mold core 310 and the movable mold core 320 are respectively equipped with inserts.
[0055] like Figure 4 As shown, the fixed mold assembly is also equipped with a glue injection nozzle, which passes through the fixed mold assembly and the fixed mold core 310 and communicates with the cylinder cavity to inject glue into the cylinder cavity.
[0056] like Figure 4 As shown, it also includes a core-pulling mechanism, which is disposed between the moving mold plate 530 and the fixed mold plate 430 and extends into the mold core. The core-pulling mechanism includes a core-pulling cylinder, a core-pulling slider, and a sliding core 140. The sliding core 140 passes through the cylindrical cavity, so that the moving mold core 320, the fixed mold core 310, and the sliding core 140 form a connection with product A (see product A). Figure 6 The product molding cavity is adapted to the shown; the sliding core 140 is connected to the core-pulling slider, and the core-pulling slider is connected to the core-pulling cylinder. The core-pulling cylinder drives the sliding core 140 to slide away from the product molding cavity by driving the core-pulling slider, thereby realizing the core-pulling molding of product A.
[0057] Combination Figure 4 and Figure 5 As shown, the mold anti-overflow glue mechanism is located between the moving mold assembly and the fixed mold assembly, and extends into the mold core. Specifically: the mold anti-overflow glue mechanism is located between the fixed mold plate 430 and the moving mold plate 530. The cylinder connecting rod 150 is assembled on the moving mold plate 530, the insertion end of the cylinder connecting rod 150 extends into the mold core and is positioned on one side of the product molding cavity, the sealing ring 200 of the cylinder connecting rod 150 faces the product molding cavity, and a sealing ring 200 is fitted at the sealing ring 200; the cylinder 110 is fixed outside the mold frame by the fixing frame 120, the connecting rod is placed inside the fixing frame 120, the output end of the cylinder 110 passes through the fixing frame 120 and connects to the connecting rod, the connecting rod is connected to the cylinder separator 130, and the cylinder separator 110... The cylinder insert 130 extends into the mold core through the moving template 530. The linkage end of the cylinder insert 130 passes through the sliding core 140, which is installed inside the mold core. One end of the sliding core 140 facing the cylinder connecting rod 150 presses against the sealing ring 200. The sealing ring 200 is clamped between the sliding core 140 and the cylinder connecting rod 150. A filling plastic part is fitted on the cylinder connecting rod 150. The insert installed on the mold core is inserted into the positioning groove of the positioning ring in the filling plastic part to position the filling plastic 160.
[0058] Combination Figures 1 to 5 As shown, the working principle of the above injection mold is as follows:
[0059] Injection: After the injection mold is installed in place, it is connected to the injection machine, and the glue in the injection machine is injected into the product molding cavity through the injection nozzle on the injection mold. It should be noted that during the glue injection stage of Product A, cylinder 110 is activated and connected to cylinder mediator 130 via a connecting rod, driving cylinder mediator 130 to move in the direction connected to cylinder 110. The driven cylinder mediator 130 moves into the sliding core 140, and the linkage end of cylinder mediator 130 is inserted into the inner hole of cylinder connecting rod 150. The threaded rod 170 placed in the inner hole is inserted into the linkage end of cylinder mediator 130. After completing the above actions, the inner hole sidewall of cylinder connecting rod 150 is expanded. The expanded inner hole sidewall (i.e., the sidewall of cylinder connecting rod 150) drives the sealing ring 200 to expand outward through the sealing ring 200. That is, the sealing ring 200, which is set between the sliding core 140, cylinder connecting rod 150 and the plastic filling part, is clamped. The expanded sealing ring 200 is tightly fitted with the inner wall of the plastic filling 160, thereby improving the sealing effect and effectively preventing glue overflow.
[0060] It should be noted that after the adhesive is injected and cooled to solidify, cylinder 110 is closed, and cylinder mediator 130 is driven to move away from cylinder connecting rod 150 to achieve a reset effect.
[0061] Mold opening: The moving module drives the moving mold core 320, the mold anti-overflow glue mechanism and the core pulling mechanism to move away from the stationary mold group to open the mold, thereby realizing the mold opening.
[0062] Core pulling: The core pulling cylinder drives the sliding core 140 to move by the core pulling slider, thereby completing the core pulling and forming.
[0063] Demolding: The driven ejector plate assembly 540 drives the ejector pin, which ejects product A from the driven mold core 320, thus completing the demolding of product A.
[0064] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
