Description

Technical Field

[0001] The present application relates to the technical field of palm-shaped bionic mold manufacturing, and in particular to a palm-shaped embryo shaping device. Background Art

[0002] In the prior art, in the production process of gloves such as latex, nitrile, PU or PVC, a palm-shaped bionic mold is usually required to perform processes such as dipping and shaping of the glove products. Among them, the quality of the palm-shaped bionic mold itself directly affects the quality of the corresponding glove products. At present, the palm-shaped bionic mold is mainly prepared by a welding process such as stir friction welding, argon arc welding, laser welding, two-protection welding or brazing after obtaining a palm-shaped blank through a die-casting process. However, the palm-shaped bionic mold prepared by this process has defects such as many pores, color difference, and a large amount of oxide impurities. Based on this, the inventors have found that the use of rotary friction welding to prepare the palm-shaped bionic mold can improve the defects of the palm-shaped bionic mold such as many pores, color difference, and a large amount of oxide impurities. However, in the traditional preparation process, the wrist opening of the palm-shaped blank after die-casting is usually elliptical, and rotary friction welding requires the wrist opening of the palm-shaped blank to be a perfect circle. At present, there is no related mold specifically used to shape the opening at the wrist of the palm-shaped blank into a perfect circle. Summary of the invention

[0003] The purpose of the present application is to provide a palm-shaped blank shaping device, which can shape the opening at the wrist of the palm-shaped blank into a perfect circle, so as to facilitate the subsequent welding process using rotary friction welding.

Specifically, the top of the lower mold and the bottom of the upper mold are respectively provided with corresponding first through grooves and second through grooves.

[0017] In some optional embodiments, a limit block is further protruding from the outer peripheral wall of the extrusion head, and on the movement path of the extrusion head, the side of the limit block facing away from the linear drive unit is used to abut against the end face of the wrist opening.

[0018] In the above technical solution, the outer peripheral wall of the extrusion head is also convexly provided with a limiting block that can abut against the end face of the wrist opening of the palm-shaped blank, which can achieve precise positioning during shaping, thereby improving the shaping effect.

Specifically, the arc segment is located at the end of the extrusion head, which facilitates the extrusion head to extend into the palm-shaped blank; the column segment is located in the area of ​​the limit block away from the linear drive unit, which facilitates shaping the wrist of the palm-shaped blank into a perfect circle. This specific form of extrusion head has the advantage of a more reasonable structure.

[0037] A palm-shaped embryo shaping device of the present application is described in detail below.

[0038] See also Figure 1 and Figure 2 An embodiment of the present application provides a palm-shaped embryo shaping device 10, including a base 100, a relatively distributed lower mold 200 and an upper mold 300, and a shaping unit 500. The lower mold 200 is installed on the top of the base 100, and a first through groove 210 is opened on the top of the lower mold 200, and a second through groove 310 corresponding to the first through groove 210 is opened on the bottom of the upper mold 300. After the lower mold 200 and the upper mold 300 are molded together, the first through groove 210 and the second through groove 310 are surrounded to form a shaping channel 400 for matching the palm-shaped embryo; the shaping unit 500 includes an extrusion head 510 and a linear drive unit 520, and the extrusion head 510 is connected to the power output end of the linear drive unit 520. The extrusion head 510 can enter the shaping channel 400 under the drive of the linear drive unit 520, and the extrusion head 510 is a rotating body; the extrusion head 510 is configured to enter the cavity of the palm-shaped embryo from the wrist opening of the palm-shaped embryo under the drive of the linear drive unit 520, and shape the surrounding wall at the wrist opening.

[0039] In the present application, the palm-shaped embryo shaping device 10 is composed of a base 100, a relatively distributed lower mold 200, an upper mold 300 and a shaping unit 500. Specifically, the top of the lower mold 200 and the bottom of the upper mold 300 are respectively provided with corresponding first through grooves 210 and second through grooves 310. The two through grooves are enclosed to form a shaping channel 400 for matching the palm-shaped embryo after the lower mold 200 and the upper mold 300 are molded together, so as to fix the palm-shaped embryo in the shaping channel 400; the shaping unit 500 In the figure, the extrusion head 510 is connected to the power output end of the linear drive unit 520 and can enter the shaping channel 400 under the drive of the linear drive unit 520. At the same time, the extrusion head 510 is a rotating body and is configured to enter the cavity of the palm-shaped embryo from the wrist opening of the palm-shaped embryo under the drive of the linear drive unit 520, thereby being able to shape the surrounding wall of the wrist opening of the palm-shaped embryo into a perfect circle, so that it can be welded by rotary friction welding later.

[0040] See also Figure 1As an example, the palm-shaped embryo shaping device 10 also includes a fastener 600. After the upper mold 300 and the lower mold 200 are molded together, one end of the fastener 600 is detachably connected to the side wall of the upper mold 300, and the other end of the fastener 600 is detachably connected to the corresponding side wall of the lower mold 200.

[0041] In this embodiment, the palm-shaped blank shaping device 10 is additionally provided with a fastener 600. Specifically, the two ends of the fastener 600 can be detachably connected to the side walls located on the same side of the upper mold 300 and the lower mold 200 after the upper mold 300 and the lower mold 200 are closed, so that the upper mold 300 and the lower mold 200 can be stably combined during shaping, so as to better shape the palm-shaped blank.

[0042] It should be noted that there is no limitation on the setting form of the fastener 600, as long as it can connect and fix the upper mold 300 and the lower mold 200 together after the mold is closed. For example, it can be in the form of a connecting plate. Specifically, one end of the connecting plate is connected to the side wall of the upper mold 300 by bolts, and the other end is also connected to the side wall of the lower mold 200 by bolts.

[0043] It should be noted that the number of fasteners 600 is not limited and can be adjusted according to actual needs. For example, a fastener 600 can be provided on two opposite sides of the mold.

[0044] It should be noted that the form of the linear drive unit 520 is not limited and can be set according to conventional choices in the field, as long as it can drive the extrusion head 510 to move linearly in and out of the palm-shaped blank, for example, it can be driven by a motor, a cylinder or an oil cylinder.

[0045] See also Figure 1 As an example, the linear drive unit 520 includes a bracket 521 and a cylinder 522, the bracket 521 is installed on the top of the base 100, the cylinder 522 is connected to the bracket 521, the power output end of the cylinder 522 is connected to the extrusion head 510, and the axis of the cylinder 522 passes through the shaping channel 400.

[0046] In this embodiment, the linear drive unit 520 is composed of a bracket 521 and a cylinder 522, and has the advantages of simple structure and high motion stability; in addition, the bracket 521 is also installed on the top of the base 100, so that the linear drive unit 520 and the mold are fixed on the same base 100, which facilitates the alignment of the linear drive unit 520 with the shaping channel 400 formed by the mold, and at the same time, it can also make the overall structure of the shaping device more compact.

[0047] As an example, the base 100 is a metal plate, and the thickness of the base 100 is 10-30 mm, for example but not limited to any one of 10 mm, 15 mm, 20 mm, 25 mm and 30 mm or a range between any two of the thicknesses.

[0048] In this embodiment, a metal plate is used as the base 100 and its thickness is limited to a specific range, so that the base 100 has relatively excellent strength and the overall structure of the shaping device can be relatively stable during shaping.

[0049] See also Figure 1 As an example, a plurality of concave and convex fittings are arranged in the circumferential direction of the mold joint of the upper mold 300 and the lower mold 200 .

[0050] In this embodiment, concave and convex fittings are arranged circumferentially at the mold-joining point of the upper mold 300 and the lower mold 200, which helps to improve the accuracy and convenience when the upper mold 300 and the lower mold 200 are joined.

[0051] It should be noted that the arrangement of the concave and convex fittings is not limited. For example, the lower mold 200 may be provided with a protrusion and the upper mold 300 may be provided with a groove; or the lower mold 200 may be provided with a groove and the upper mold 300 may be provided with a protrusion. The specific arrangement can be adjusted according to actual needs.

[0052] See also Figure 1 As an example, the top edge of the lower mold 200 is provided with a plurality of limiting protrusions 220 distributed at intervals along the circumference of the lower mold 200, and the bottom edge of the upper mold 300 is provided with a plurality of limiting grooves 320 corresponding to the plurality of limiting protrusions 220 one by one.

[0053] It should be noted that since the material of the palm-shaped blank is usually aluminum alloy, in order to more effectively assist in shaping, the shaping device can also be given a heating function so that the palm-shaped blank can be extruded and shaped after it softens.

[0054] See also Figure 2 As an example, the lower mold 200 is provided with a plurality of first heating channels 230 distributed at circumferential intervals along the first through groove 210 , and the upper mold 300 is provided with a plurality of second heating channels 330 distributed at circumferential intervals along the second through groove 310 .

[0055] In this embodiment, the upper mold 300 and the lower mold 200 are respectively provided with a plurality of first heating channels 230 and second heating channels 330 distributed at circumferential intervals along the first through grooves 210 and the second through grooves 310. By providing the heating channels, the wrist opening of the palm-shaped blank can be softened by high temperature before the shaping unit 500 is used to shape the palm-shaped blank, so that the elliptical wrist opening can be shaped into a perfect circle more easily and effectively.

[0056] See also Figure 2 As an example, taking the joining line of the upper mold 300 and the lower mold 200 as the symmetry axis, the plurality of first heating channels 230 and the plurality of second heating channels 330 are symmetrically distributed one by one.

[0057] In this embodiment, multiple first heating channels 230 and multiple second heating channels 330 are arranged in a symmetrical distribution about the mold line, which helps to improve the heating uniformity of the palm-shaped blank, thereby improving the shaping effect; in addition, it can also make the overall structure of the shaping device more regular.

[0058] It should be noted that there is no limitation on the method of heating the palm-shaped blank by using the heating channel, for example, an electric heating tube may be installed in the heating channel.

[0059] It should be noted that the length dimension of the shaping channel 400 is not limited and can be adjusted according to actual needs. For example, the shaping channel 400 can be used only to accommodate and fix the palm-shaped blank during shaping, or it can be used to accommodate the palm-shaped blank and the extrusion head 510 at the same time during shaping.

[0060] See also Figure 3 As an example, on the movement path of the extrusion head 510, the shaping channel 400 has a first channel 410 and a second channel 420 that are connected, and the surrounding wall of the second channel 420 is used to fix the palm-shaped embryo. The extrusion head 510 moves in the first channel 410 and part of the extrusion head 510 can enter the palm-shaped embryo.

[0061] In this embodiment, on the movement path of the extrusion head 510, the shaping channel 400 is set to the form of cooperation between the first channel 410 and the second channel 420. Specifically, the peripheral wall of the second channel 420 is used to fix the palm-shaped embryo. The extrusion head 510 moves in the first channel 410 and part of the extrusion head 510 can enter the cavity of the palm-shaped embryo, so that the extrusion head 510 is basically completely wrapped during the shaping process, thereby being able to better protect the extrusion head 510; at the same time, it is also convenient for the extrusion head 510 to be more accurately connected and matched with the wrist opening of the palm-shaped embryo.

[0062] It should be noted that in order to prepare high-quality palm-shaped blanks, the outer wall of the palm-shaped blank at the wrist is usually provided with a protruding process edge. In order to effectively fix the palm-shaped blank during the shaping process and to improve the problem that it is easy to wrinkle and deform due to extrusion and easy to shift away from the extrusion head 510, the corresponding structure of the mold can be optimized according to the protruding process edge.

[0063] See also Figure 3 As an example, a gradient channel 430 is provided between the first channel 410 and the second channel 420, and the inner diameter of the gradient channel 430 at one end close to the first channel 410 is larger than the inner diameter at one end away from the first channel 410, and the surrounding wall of the gradient channel 430 is used to fix the wrist of the palm-shaped embryo.

[0064] In this embodiment, a gradient channel 430 for fixing the wrist of the palm-shaped embryo is added between the first channel 410 and the second channel 420, which can improve the fixation stability of the palm-shaped embryo during the plastic surgery process and improve the problem of wrinkles on the palm-shaped embryo during the plastic surgery process.

[0065] See also Figure 4 As an example, a limit block 511 is also protruding from the outer peripheral wall of the extrusion head 510. On the movement path of the extrusion head 510, the side of the limit block 511 away from the linear drive unit 520 is used to abut against the end surface of the wrist opening.

[0066] In this embodiment, the outer peripheral wall of the extrusion head 510 is also provided with a limit block 511 that can abut against the end face of the wrist opening of the palm-shaped blank, so as to achieve precise positioning during shaping, thereby improving the shaping effect.

[0067] It should be noted that the specific configuration of the extrusion head 510 is not limited and can be set according to conventional choices in the field, as long as it can enter the cavity of the palm-shaped embryo and shape its wrist opening under the drive of the linear drive unit 520.

[0068] See also Figure 4 As an example, the extrusion head 510 includes an arc segment 512 and a column segment 513 connected in sequence, the arc segment 512 is located at the end of the extrusion head 510 so as to be used to extend into the palm-shaped embryo; the column segment 513 is located in the area of ​​the limit block 511 away from the linear drive unit 520, and is used to shape the wrist of the palm-shaped embryo into a columnar shape (that is, the contour shape of the inner wall at the wrist opening is circular).

[0069] In this embodiment, the extrusion head 510 is configured to be a combination of an arc segment 512 and a column segment 513. Specifically, the arc segment 512 is located at the end of the extrusion head 510, which facilitates the extrusion head 510 to extend into the palm-shaped blank; the column segment 513 is located in the area of ​​the limit block 511 away from the linear drive unit 520, which facilitates shaping the wrist of the palm-shaped blank into a perfect circle. This particular form of the extrusion head 510 has the advantage of a more reasonable structure.

[0070] It should be noted that any structural or functional unit not specifically described or limited in the shaping device may be configured according to conventional selections in the art.

[0071] In order to better understand the technical solution, a schematic diagram of the structure of the palm-shaped embryo and the palm-shaped embryo shaping device after assembly is provided here for auxiliary explanation. For details, please refer to Figure 5The palm-shaped embryo 20 is fixed in the shaping channel 400 formed by the upper mold 300 and the lower mold 200. The extrusion head 510, driven by the linear drive unit 520, can enter the cavity of the palm-shaped embryo 20 from the wrist opening of the palm-shaped embryo 20 and shape the wrist opening of the palm-shaped embryo 20.
