Description

Technical Field

[0001] The utility model relates to the field of mold equipment, in particular to a mold for manufacturing a medical control liquid tube. Background Art

[0002] When a mold for manufacturing an existing medical control fluid tube is used to eject a workpiece, appearance problems such as slider joint lines are usually formed on the workpiece's exterior surface, which is detrimental to the appearance of the workpiece itself. Utility Model Content

[0003] The utility model aims to provide a mold for manufacturing a medical control liquid tube, which can improve the ejection effect of a workpiece and avoid a poor appearance of the workpiece.

[0004] In order to solve the above technical problems, the utility model provides a mold for manufacturing a medical control liquid tube, including a push plate and a module base movably placed inside the push plate, the injection molding position of the module base is parallel to the push plate, wherein the workpiece is placed in the injection molding position of the module base, and an ejection assembly is connected to one side of the push plate. When the ejection assembly pushes the push plate to move, the push plate moves away from the module base, so that the injection molding position of the module base moves from the inside of the push plate to the outside of the push plate.

[0005] Furthermore, it includes an inner needle of the sleeve, one end of which passes through the mold base and is arranged near the injection position, the workpiece is sleeved on the end of the inner needle of the sleeve, and the other end of the inner needle of the sleeve is connected to the bottom plate.

[0006] Furthermore, the sleeve is movably sleeved on the outer periphery of the inner needle of the sleeve, and one end of the sleeve is against the workpiece.

[0007] Furthermore, one side of the ejection assembly is connected to a pin plate, which has a limit groove. The end of the sleeve away from the workpiece has a protrusion, and the protrusion is buckled in the limit groove. When the ejection assembly pushes the push plate to move, the limit groove moves in the direction away from the protrusion.

[0008] Furthermore, a positioning plate is provided on one side of the push plate close to the bottom plate, a protective seat is provided on the side of the positioning plate, and the ejection assembly is movably arranged on the protective seat.

[0009] Furthermore, a sliding block is connected to one side of the push plate, and one end of the sliding block abuts against one end of the ejection assembly.

[0010] Furthermore, a guide slide seat is connected to one side of the push plate, the sliding block is movably arranged in the guide slide seat, and an elastic member is connected between the guide slide seat and the sliding block.

[0011] Furthermore, a toggle block is movably provided in the protection seat.

[0012] The beneficial effect of the present invention is that when the injection molding is completed and the workpiece needs to be ejected, the ejection assembly first pushes the push plate to move. At this time, due to the movable arrangement between the push plate and the module seat, the module seat remains stationary when the push plate moves, thereby ensuring that the position of the workpiece remains unchanged when the push plate moves. Subsequently, after the push plate is moved, the module seat moves relatively from the inside of the push plate to the outside of the push plate, so that the original wrapping limit of the push plate on the outer periphery of the module seat disappears, thereby reducing the constraint of the module seat on the workpiece in the injection molding position, so that when the workpiece is ejected for the second time, the workpiece can be more easily ejected from the module seat, thereby increasing the effect of the workpiece ejection process, and also avoiding the situation where the appearance of the workpiece is poor due to sliding and the like during the ejection process.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0018] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms cannot be understood as limiting the present invention.

[0019] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0020] like Figure 1-3 As described, the utility model provides a mold for manufacturing a medical control liquid tube, including a push plate 1, a module base 2 movably placed inside the push plate 1, the injection molding position of the module base 2 is parallel to the push plate 1, wherein the workpiece 3 is placed in the injection molding position of the module base 2, and an ejection component 4 is connected to one side of the push plate 1. When the ejection component 4 pushes the push plate 1 to move, the push plate 1 moves away from the module base 2, so that the injection molding position of the module base 2 moves from the inside of the push plate 1 to the outside of the push plate 1.

[0021] When the injection molding is completed and the workpiece needs to be ejected, the ejection assembly first pushes the push plate to move. At this time, due to the movable setting between the push plate and the module seat, the module seat remains stationary when the push plate moves, and thus the position of the workpiece remains unchanged when the push plate moves. Subsequently, after the push plate is moved, the module seat moves relatively from the inside of the push plate to the outside of the push plate, so that the original wrapping limit of the push plate on the outer periphery of the module seat disappears, thereby reducing the constraint of the module seat on the workpiece in the injection molding position, so that when the workpiece is ejected for the second time, the workpiece can be more easily ejected from the module seat, thereby increasing the effect of the workpiece ejection process and also avoiding the situation where the appearance of the workpiece is poor due to friction during the ejection process.

[0022] Among them, when the module seat is placed inside the push plate, the outer periphery of the module seat is constrained by the push plate itself, so that the module seat squeezes the workpiece in the injection molding position inward. After the push plate and the module seat move relative to each other, the outer periphery of the module seat loses the wrapping limit of the push plate, so that the module seat no longer squeezes the workpiece in the injection molding position, thereby reducing the constraint force between the module seat and the workpiece, so as to facilitate the subsequent ejection operation of the workpiece.

[0023] In one embodiment of the present solution, the ejection assembly is driven by an ejection mechanism of the injection molding machine, such as a cylinder or other components, so that the ejection assembly can push the push plate to move.

[0024] Preferably, it includes an inner needle 5 of the sleeve, one end of which passes through the mold base 2 and is arranged close to the injection position, the workpiece 3 is sleeved on the end of the inner needle 5 of the sleeve, and the other end of the inner needle 5 is connected to the bottom plate 6.

[0025] Specifically, during the injection molding process, the workpiece is shaped by the injection molding position and the end of the needle in the sleeve, so that the workpiece after injection molding is placed in the injection molding position and is sleeved on the end of the needle in the sleeve. In the process of moving the push plate and ejecting the workpiece, the workpiece can be supported and positioned by the end of the needle in the sleeve to avoid problems such as shaking of the workpiece.

[0026] Preferably, a sleeve 7 is movably sleeved on the outer periphery of the sleeve inner needle 5 , and one end of the sleeve 7 is against the workpiece 3 .

[0027] Specifically, after the push plate moves, the sleeve is driven to move toward the workpiece, so that the sleeve is ejected for the second time, and then the workpiece is ejected. Since the restraint force of the module base on the workpiece is reduced at this time, the sleeve can eject the workpiece more easily.

[0028] Among them, since the sleeve is sleeved on the outer periphery of the sleeve inner needle, the sleeve can be guided by the sleeve inner needle during the process of ejecting the workpiece, thereby increasing the accuracy of ejection.

[0029] In one embodiment of this solution, the ejector sleeve can be driven by a driving member such as a pneumatic cylinder or a hydraulic cylinder to facilitate ejecting the workpiece.

[0030] Preferably, one side of the ejection assembly 4 is connected to a pin plate 8, which has a limiting groove 9. The end of the sleeve 7 away from the workpiece 3 has a protrusion 10, and the protrusion 10 is buckled in the limiting groove 9. When the ejection assembly 4 pushes the push plate 1 to move, the limiting groove 9 moves in the direction away from the protrusion 10.

[0031] Specifically, the limiting groove on the ejector plate cooperates with the limiting portion of the protrusion, so that the ejector plate limits the ejector sleeve. When the ejection assembly pushes the push plate to move, the ejection assembly simultaneously pushes the ejector plate to move, thereby causing the limiting groove to move away from the protrusion, so that a certain distance is formed between the limiting groove and the protrusion, so as to leave room for the subsequent ejection of the workpiece by the ejector sleeve.

[0032] In one embodiment of this solution, a groove is provided on one side of the ejector plate, and a protrusion is provided on one side of the ejector assembly. The protrusion is buckled in the groove, so that when the ejector assembly moves, the ejector plate is driven to move as well.

[0033] It is worth mentioning that there is an activity space above the ejector plate, and there are multiple guide pillars in the activity space. One end of the guide pillar passes through the ejector plate. When the ejector plate moves, the ejector plate moves toward the activity space, and at the same time, it is guided and limited by the guide pillars to ensure the stability of the ejector plate during movement.

[0034] Preferably, the push plate 1 has a positioning plate 11 on one side close to the bottom plate 6 , and a protective seat 12 is provided on the side of the positioning plate 11 , and the ejection assembly 4 is movably disposed on the protective seat 12 .

[0035] Specifically, the protective seat limits the moving direction of the ejector assembly, thereby ensuring the accuracy of the movement of the ejector assembly and further ensuring the accuracy of the movement of the push plate and the ejector plate.

[0036] In particular, the protective seat is a "C"-shaped structure protruding from the side of the positioning plate, so that the side of the positioning plate and the protective seat form a hollow limiting cavity, and the ejection assembly is movably placed in the limiting cavity, so that the ejection assembly can move relative to the protective seat, and the moving direction of the ejection assembly can be limited by the limiting cavity.

[0037] In addition, the positioning plate is located between the push plate and the bottom plate, and the positioning plate is supported and limited on all sides by other components of the mold, so that the position of the positioning plate itself is fixed relative to the mold.

[0038] In one embodiment of this solution, one side of the module base is connected to the positioning plate by bolts, buckles and other components to ensure that when the push plate moves, the module base will not move with the push plate.

[0039] Preferably, a sliding block 13 is connected to one side of the push plate 1, and one end of the sliding block 13 abuts against one end of the ejection assembly 4, so that when the ejection assembly moves, the ejection assembly pushes one end of the sliding block to drive the push plate to move.

[0040] Specifically, the sliding block has a protruding structure on one side away from the push plate, and the protruding structure pushes out the end of the ejection assembly, so that when the ejection assembly moves, the protruding structure pushes the sliding block, and then the push plate moves up through the sliding block.

[0041] Preferably, a guide slide seat 14 is connected to one side of the push plate 1 , the sliding block 13 is movably disposed in the guide slide seat 14 , and an elastic member 15 is connected between the guide slide seat 14 and the sliding block 13 .

[0042] Specifically, under the action of the elastic member, the sliding block pops outward, so that one end of the sliding block is against one end of the ejection assembly. When the ejection assembly needs to be installed or removed, the sliding block can be pushed inward along the guide slide seat to make the elastic member contract and ensure that the sliding block is placed inside the guide slide seat. At this time, the sliding block will not affect the ejection assembly.

[0043] In one embodiment of this solution, the elastic member is a spring.

[0044] Preferably, a toggle block 16 is movably provided in the protective seat 12, so that when the sliding block needs to be pushed inward along the guide slide seat, the sliding block can be pushed by moving the toggle block, thereby increasing the convenience of moving the sliding block.

[0045] Specifically, the toggle block is movably placed in the limiting cavity formed between the protective seat and the positioning plate, and one end of the toggle block is against the protruding structure position of the sliding block. When the toggle block moves relative to the protective seat, the toggle block pushes the protruding structure position of the sliding block, thereby driving the sliding block to shrink and slide inward along the guide slide seat, so that the protruding structure of the sliding block avoids the end of the ejection assembly, so that the sliding block and the ejection assembly no longer resist each other.

[0046] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that is the same or similar to that of the present application falls within the scope of protection of the present invention.
