[0002] Slippers are shoes without uppers on the back half, usually worn indoors. Usually refers to shoes that can be separated from the foot by movement of the shoe or foot, or three protrusions parallel to the sole of the foot, or the inner surface of the sole is located on a plane that is coplanar with the extension line of the calf axis without hurting the shoe or foot. Slippers have been widely used in people's daily lives. Slippers in today's era sometimes also include sandals worn outside in summer. Compared with slippers worn indoors, there are more styles and more exquisite. The materials are often quite light and soft leather, plastic, cloth, etc. Among them, the most common are waterproof plastic slippers produced and processed using plastics using injection molds.

[0003] Conventional injection molds use hydraulic devices to structurally connect the upper mold and the lower mold. If the hydraulic device fails during the process of lifting or pushing down the structure, it may cause the mold in an active state to fall, thereby causing structural damage.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an automatic demoulding mechanism and a slipper Labang injection mold are proposed. Utility Model Content

[0007] Furthermore, the device seat group includes a base, fixed piles and a coupling seat, the left and right sides of the base are equipped with fixed piles, and the left and right sides of the base are equipped with a coupling seat close to the Labang lower mold seat.

[0008] Furthermore, the bottom of the support column and the fixing pile are fixedly connected to each other, and the support columns are distributed at four diagonal positions of the base.

[0009] Furthermore, the driving frame assembly includes a stabilizing beam, a servo motor and a worm gear. The servo motors are installed at both the front and rear ends of the stabilizing beam, and the worm gear is installed at the power output end of the servo motor through a coupling.

[0010] Furthermore, the driving frame assembly also includes a threaded slider and a connecting frame. The threaded slider is threadedly mounted on the surface of the worm, and one side of the threaded slider is connected to the connecting frame.

[0011] Furthermore, the threaded sliders are symmetrically connected to the four diagonal portions of the connecting frame, and the threaded sliders and the connecting frame are welded to each other.

[0012] Furthermore, the bottom of the worm is rotatably connected to the top of the coupling seat, the Labang upper mold is fixedly installed at the bottom center of the connecting frame, and the Labang upper mold and the Labang lower mold base are arranged in a nested structure with each other.

[0014] The utility model provides an automatic demoulding mechanism and a slipper Labang injection mold, which have the following beneficial effects:

[0015] 1. The utility model has a demoulding assembly installed inside the Labang lower mold base, wherein the lower mold is installed on the top of the connecting base. When the Labang upper mold is driven by the driving frame group to perform structural docking with the Labang lower mold base and the lower mold inside, the hydraulic push rod at the bottom of the connecting base will push the connecting base with the lower mold installed on the top from bottom to top in the vertical direction, so that the lower mold and the Labang upper mold can be effectively and tightly docked. By using the above structure, on the one hand, the tightness of the structural docking between the lower mold and the Labang upper mold can be ensured to the greatest extent, and the overflow of the injection plastic between the two after docking can be avoided as much as possible. On the other hand, by using the nested structure of the Labang upper mold and the Labang lower mold base, it can be further avoided that the molten injection plastic may overflow after the lower mold and the Labang upper mold are docked, which may affect the operating personnel.

[0016] 2. The utility model, through the spring buffer columns installed around the Labang lower die base, enables the Labang upper die to be connected with the Labang lower die base from top to bottom in the vertical direction under the drive of the driving frame group, thereby playing a role of structural support and buffering, avoiding structural damage caused by the fall of the Labang upper die when the driving frame group fails. In addition, through the use of a worm, the threaded sliders at the four diagonal parts of the connecting frame are connected to the worm, so that when the servo motor drives the worm to rotate axially in the vertical direction, the connecting frame with the Labang upper die connected to the bottom can move up and down with the assistance of the threaded sliders, while having sufficient lifting stability, further avoiding the Labang upper die and the Labang lower die from slipping or falling during the process of structural docking or separation, so as to ensure the stability of the device structure operation.

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figures 1 to 3As shown, an automatic demoulding mechanism and a slipper Labang injection mold include a device seat group 1 and a demoulding component 7. Support columns 2 are vertically installed on the left and right sides of the device seat group 1, and a driving frame group 3 is installed on the top of the support column 2. The center of the bottom of the driving frame group 3 is connected to a Labang upper mold 4, and a Labang lower mold seat 5 is arranged directly below the Labang upper mold 4. At the same time, spring buffer columns 6 are installed around the Labang lower mold seat 5. The demoulding component 7 is installed at the inner bottom end of the Labang lower mold seat 5. The demoulding component 7 includes a connecting seat 701, a lower mold 702, a hydraulic push rod 703 and a fixing frame 704. The lower mold 702 is installed on the top surface of the connecting seat 701, and the hydraulic push rods 703 are symmetrically installed on the bottom of the connecting seat 701, and the fixing frame 704 is installed on the bottom of the hydraulic push rod 703. The device seat group 1 includes a base 10 1. Fixed piles 102 and coupling seats 103. Fixed piles 102 are installed on both sides of the base 101, and coupling seats 103 are installed on one side of the left and right sides of the base 101 close to the Labang lower mold base 5. The bottom of the support column 2 is fixedly connected to the fixed piles 102, and the support columns 2 are distributed at the four diagonal positions of the base 101. A demolding assembly 7 is installed inside the Labang lower mold base 5, wherein the lower mold 702 is installed on the top of the connecting seat 701. When the Labang upper mold 4 is driven by the driving frame group 3 to structurally dock with the Labang lower mold base 5 and the lower mold 702 inside, the hydraulic push rod 703 at the bottom of the connecting seat 701 will push the connecting seat 701 with the lower mold 702 installed on the top from bottom to top in the vertical direction, so that the lower mold 702 and the Labang upper mold 4 are effectively and tightly docked.

[0023] like Figures 1 to 3As shown, the driving frame group 3 includes a stabilizing beam 301, a servo motor 302 and a worm 303. The servo motor 302 is installed at both the front and rear ends of the stabilizing beam 301, and the worm 303 is installed at the power output end of the servo motor 302 through a coupling. The driving frame group 3 also includes a threaded slider 304 and a connecting frame 305. The threaded slider 304 is threadedly installed on the surface of the worm 303, and one side of the threaded slider 304 is connected to the connecting frame 305. The threaded slider 304 is symmetrically connected to the diagonal parts of the connecting frame 305, and the threaded slider 304 and the connecting frame 305 are welded to each other. The bottom of the worm 303 is rotatably connected to the top of the coupling seat 103, and the Labang upper mold 4 is fixedly installed on the connecting frame 305. The Labang upper mold 4 and the Labang lower mold base 5 are arranged in a nested structure with each other. Through the spring buffer columns 6 installed around the Labang lower mold base 5, the Labang upper mold 4 is driven by the driving frame group 3 to connect with the Labang lower mold base 5 from top to bottom in the vertical direction, thereby playing a role of structural support and buffering. In addition, through the use of the worm 303, the threaded sliders 304 at the four diagonal parts of the connecting frame 305 are threadedly connected to the worm 303, so that when the servo motor 302 drives the worm 303 to rotate axially in the vertical direction, the connecting frame 305 with the Labang upper mold 4 connected to the bottom can be translated up and down with the assistance of the threaded slider 304, while having sufficient lifting stability.

[0024] In summary, if Figures 1 to 3 As shown, when the automatic demoulding mechanism and the slipper Labang injection mold are used, the driving frame group 3 installed at the upper end of the support column 2 is first started. Under the operation of the servo motors 302 at both ends of the stabilizing beam 301, the worm 303 structurally connected thereto is axially rotated in the vertical direction under the structural support of the coupling seat 103. As the worm 303 rotates, the connecting frame 305 with the Labang upper mold 4 installed in the center of the bottom will translate from top to bottom in the vertical direction along the surface of the worm 303 through the threaded slider 304;

[0025] As the Labang upper mold 4 and the Labang lower mold base 5 below are nested and docked, the demoulding assembly 7 inside the Labang lower mold base 5 also operates at the same time. The hydraulic push rod 703 vertically installed inside the Labang lower mold base 5 by the fixed frame 704 will be telescopically adjusted in the vertical direction, so that the lower mold 702 connected to it through the connecting seat 701 at the top is structurally lifted from bottom to top in the vertical direction until the lower mold 702 is tightly docked with the Labang lower mold base 5. In this process, as the Labang lower mold base 5 and the Labang upper mold 4 are docked, the Labang upper mold 4 will compress the spring buffer column 6 installed around the Labang lower mold base 5. The spring buffer column 6 will cooperate with the drive of the driving frame group 3 due to its own structural resilience, so that the Labang upper mold 4 can maintain a stable state to the greatest extent;

[0026] After that, the injection plastic is injected between the Labang upper mold 4 and the lower mold 702. When the injection molding is completed and the injection molded part is solidified, during the reverse operation of the driving frame assembly 3, the Labang upper mold 4 will be structurally separated from the Labang lower mold base 5 and the lower mold 702. At the same time, under the structural extension and contraction of the hydraulic push rod 703, the lower mold 702 on the top of the connecting seat 701 will be further pushed out from the inside of the Labang lower mold base 5, so that the operator can quickly take out the injection molded part in the lower mold 702.

[0027] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
