Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, and in particular to a variable cavity injection mold. Background Technology

[0002] In injection molding, the mold is the core element, precisely defining the product's shape. During injection, high-temperature molten plastic is injected into the mold cavity, gradually solidifying after cooling to form the desired product. During this cooling stage, to accelerate plastic solidification, a cooling pipe is connected to a specific side of the mold. Various cooling media circulate inside the cooling pipe, efficiently absorbing the heat released during solidification and significantly accelerating the cooling rate. However, while screws can ensure a stable connection between the cooling pipe and the mold, their drawbacks become apparent during actual injection molding production when blockages or leaks require timely repair or replacement. Due to the nature of screw fixation, disassembly is extremely complex, often requiring technicians to spend considerable time removing numerous screws. This not only delays repairs and extends equipment downtime but can also severely disrupt the entire production schedule, impacting production efficiency and product delivery time.

[0028] Example 1

[0029] Reference Figures 2-6 This is the first embodiment of the present invention. This embodiment provides a variable cavity injection mold, which includes a clamping component 200, a limiting component 300, and a main body component 100. The three components work together to allow for quick assembly and disassembly of the cooling pipe.

[0030] The clamping assembly 200 includes a clamping member 201, which includes a clamping frame 201a, a movable block 201b, a drive frame 201c, a drive rod 201d, and a push rod 201e. The movable block 201b is fixed to one side of the clamping frame 201a, the drive frame 201c is hinged to one side of the movable block 201b, the drive rod 201d is fixed to one side of the drive frame 201c, and the push rod 201e is hinged to one end of the drive rod 201d.

[0031] Two sets of clamping components 201 are respectively set on both sides of the cooling pipe 103. When it is necessary to fix the cooling pipe 103, the push rod 201e is moved. The movement of the push rod 201e can drive the drive rod 201d to move. At this time, the movement of the drive rod 201d can drive the drive frame 201c to move. The drive frame 201c will drive the movable block 201b to move towards each other. The movement of the movable block 201b will drive the clamping frame 201a to move. The clamping frame 201a moves to contact both sides of the cooling pipe 103, thereby clamping the cooling pipe 103.

[0032] The limiting component 300 is disposed on one side of the clamping member 201 and includes the limiting member 301, which includes a limiting rod 301a, a limiting block 301b, a moving column 301c, and a support sleeve 301d. The limiting rod 301a is disposed on one side of the clamping member 201, the limiting block 301b is disposed on the top of the limiting rod 301a, the moving column 301c is fixed to the top of the limiting block 301b, and the support sleeve 301d is sleeved on the outside of the moving column 301c. The support sleeve 301d and the moving column 301c are movably connected.

[0033] A limiting groove corresponding to the limiting block 301b is provided on the limiting rod 301a. By engaging the limiting block 301b with the limiting groove, the push rod 201e can be limited, preventing the push rod 201e from moving on its own and causing the clamping to loosen. When it is necessary to release the limitation on the push rod 201e, the moving column 301c is moved. The moving column 301c can drive the limiting block 301b to separate from the limiting groove, thereby releasing the limitation on the push rod 201e. The support sleeve 301d is fixed to the top of the moving block 202d. The support sleeve 301d can support the moving column 301c and prevent the moving column 301c from shifting.

[0034] Example 2

[0035] Reference Figures 2-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] Specifically, the clamping assembly 200 also includes a support member 202, which is disposed on the drive rod 201d. A support bar 202a is inserted into one side of the drive rod 201d, and the support bar 202a and the drive rod 201d are rotatably connected by a pivot.

[0037] There are two support bars 202a, both of which are fixed to one side of the mounting frame 101. The support bars 202a can support the drive rod 201d and prevent the drive rod 201d from shifting.

[0038] Specifically, a slider 202b is fixed to the bottom of the push rod 201e, and a spring 202c is fixed to one side of the slider 202b.

[0039] There are two sliders 202b, both fixed to the bottom of the push rod 201e. A groove corresponding to the slider 202b is provided on the mounting frame 101. There are two springs 202c, both fixed to the inner wall of the groove. When the push rod 201e moves, it can drive the slider 202b to move. The movement of the slider 202b can apply a pulling force to the spring 202c. After the limit on the push rod 201e is released, the rebound force of the spring 202c can drive the push rod 201e back to its original position.

[0040] Specifically, a movable block 202d is fixed on one side of the push rod 201e. The movable block 202d is sleeved on the outside of the limiting rod 301a, and the movable block 202d and the limiting rod 301a are movably connected.

[0041] When it is necessary to move the push rod 201e, the moving block 202d is moved. The movement of the moving block 202d can drive the push rod 201e to move. The moving column 301c is inserted into the top of the moving block 202d, and the moving column 301c is movably connected to the moving block 202d.

[0042] Specifically, the limiting component 300 also includes a movable part 302, which is disposed on the limiting rod 301a, and a positioning plate 302a is fixed at one end of the limiting rod 301a.

[0043] There are two positioning plates 302a, both of which are fixed to the top of the mounting frame 101. The positioning plates 302a can support the limiting rod 301a and prevent the limiting rod 301a from shifting.

[0044] Specifically, a rack 302b is fixed to the top of the movable column 301c, and a gear 302c is provided on one side of the rack 302b, with the rack 302b and the gear 302c meshing.

[0045] When it is necessary to move the movable column 301c, the gear 302c is rotated. The rotation of the gear 302c can drive the rack 302b to move, and the movement of the rack 302b can drive the movable column 301c to move.

[0046] A torsion spring is fixed on one side of gear 302c. One end of the torsion spring is fixed to the inner wall of support sleeve 301d. When gear 302c is rotated, a torsional force can be applied to the torsion spring. When gear 302c is released, the force of the torsion spring can drive gear 302c to rotate back to its original position.

[0047] Specifically, a positioning pin 302d is inserted into one side of the gear 302c, and the positioning pin 302d and the gear 302c are rotatably connected by a rotating shaft.

[0048] The positioning pin 302d is fixed to the inner wall of the support sleeve 301d. The positioning pin 302d can support the gear 302c and prevent the gear 302c from shifting.

[0049] Example 3

[0050] Reference Figures 1-6 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0051] Specifically, a movable rod 302e is fixed to one side of the gear 302c, and a lever 302f is fixed to one end of the movable rod 302e.

[0052] When it is necessary to rotate the gear 302c, the gear 302c can be rotated by moving the moving rod 302e. The setting of the dial 302f makes it convenient for the user to move the moving rod 302e.

[0053] Specifically, it also includes a main component 100, which is located on one side of the clamping frame 201a, including a mounting frame 101 and a mold 102. The mounting frame 101 is located on one side of the clamping frame 201a, and the mold 102 is fixed to one side of the mounting frame 101.

[0054] As a core element in the injection molding process, the mold 102 precisely defines the molding outline of the product. When the injection molding operation is performed, the high-temperature plastic melt is injected into the cavity of the mold 102, and after the cooling process, it gradually solidifies, finally shaping the product into the predetermined shape. The installation frame 101 facilitates the installation of the cooling pipe 103.

[0055] Specifically, a cooling pipe 103 is provided on one side of the clamping frame 201a.

[0056] Various cooling media typically circulate inside the cooling pipe 103. These media can efficiently absorb the heat released by the plastic during the solidification process, thereby significantly accelerating the cooling rate of the plastic.

[0057] When it is necessary to fix the cooling pipe 103, first release the limit on the push rod 201e, and move the dial plate 302f. The dial plate 302f drives the moving rod 302e to move. At this time, the movement of the moving rod 302e will drive the gear 302c to rotate. When the gear 302c rotates, it can apply a torsional force to the torsion spring. Then the rotation of the gear 302c will drive the rack 302b to move. The movement of the rack 302b can drive the moving column 301c to move. The moving column 301c can drive the limiting block 301b to separate from the limiting groove, thereby releasing the limit on the push rod 201e. Then the moving block 202d can be moved. The movement of the moving block 202d can drive the push rod 201e to move.

[0058] The movement of push rod 201e can drive drive rod 201d to move. At this time, the movement of drive rod 201d can drive drive frame 201c to move. Drive frame 201c will drive movable block 201b to move towards each other. The movement of movable block 201b will drive clamping frame 201a to move. Clamping frame 201a moves to contact both sides of cooling pipe 103, thereby clamping cooling pipe 103. Then, release the lever 302f. At this time, the force of the torsion spring rotation can drive gear 302c to rotate. Then, limit block 301b can engage with limit groove, thereby limiting push rod 201e and preventing push rod 201e from moving on its own and causing clamping to loosen.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
