That is, the terms "include", "including", "comprising", "including", "comprising" and / or "comprising" are used to indicate that the item so described is among the items so listed, but that other items are also possible.

[0034] These and other features and characteristics of the present disclosure, the manner of operation, and the functions of the related elements of structure and the combination of parts and economies of manufacture will become more apparent upon consideration of the following description and the appended claims with reference to the accompanying drawings. It is expressly understood that the drawings are only for purposes of illustration and are not intended to limit the scope of the disclosure. It should be understood that the drawings are not necessarily to scale.

[0035] Various structural diagrams are used in the present disclosure to illustrate various modifications according to embodiments of the present disclosure. It should be understood that the foregoing or the following structures are not intended to limit the present disclosure. The scope of protection of the present disclosure is subject to the claims.

[0036] The air bag type flexible clamp currently used on the market (as shown in particular in Figure 1 , a traditional air bag type outer support clamp structure) is bound by traditional mechanical processing and manufacturing and cannot directly process an entire machine containing all parts. Instead, individual parts need to be assembled and configured, so the volume of the product is limited by the size of the mounting hole, ultimately resulting in the inability to grasp very small and closely arranged objects. Moreover, the multiple influences of metal machining, assembly process, and traditional mold manufacturing process require more manpower and resources to control product consistency, resulting in high costs.

[0037] In order to overcome the shortcomings of the prior art described above, the present disclosure provides a manufacturing mold for an outer support type air bag type flexible clamp, as shown in Figures 2-9 , which at least includes:

[0038] An upper mold 1, a mold core 2, a lower mold 3 and a glue injection plug 4; the mold core 2 is formed by 3D printing; the upper mold 1 and the lower mold 3 are inserted into the mold core 2 from the top and the bottom respectively; the glue injection plug 4 is arranged on one side of the mold core 2.

[0039] A flow channel 10 is arranged in the upper mold 1, the mold core 2 and the lower mold 3; a glue outlet hole 5 connected with the flow channel 10 is arranged on the upper mold 1; a glue injection hole 6 connected with the flow channel 10 is arranged on the lower mold 3.

[0040] In some embodiments, the upper mold 1 and the mold core 2, and the lower mold 3 and the mold core 2 are fixed by using a latch.

[0041] In some embodiments, at least one mold cleaning hole 7 is arranged on the lower mold 3, which is locked by a screw during the glue injection operation.

[0042] In some embodiments, at least one glue overflow ring hole 8 is arranged on the upper mold 1, which is used to discharge the air bubbles in the mold core 2 during the glue injection operation.

[0043] In some embodiments, the glue outlet hole 5 is designed as a tapered hole, which can discharge the excess glue and adjust the pressure difference in time. During the glue injection operation, if the glue is discharged too fast, the glue may flow away from the top before flowing into the small parts of the clamp; if the glue is discharged too slowly, the pressure at the glue injection position is too large, and the glue injection head is easy to be pulled out, so it needs to be specially designed and adjusted.

[0044] In some embodiments, as shown in FIG. 1, in order to prevent the air bag from being inflated and pulled out during ventilation, one or more air bag sealing structures 9 are arranged in the mold core 2. Figure 9

[0045] In some embodiments, the flow channel 10 in the mold core 2 is formed by the grooves of the upper mold 1 and the lower mold 3 when the upper mold 1 and the lower mold 3 are successfully spliced.

[0046] In some embodiments, the glue injection plug 4 is connected with one side of the flow channel 10 in the mold core 2; the glue injection plug 4 is fixedly connected with the mold core 2 by a thread.

[0047] In some embodiments, the shape of the glue injection plug 4 can be changed to any form as long as it can temporarily block the position during the glue injection operation.

[0048] In some embodiments, as shown in FIG. 1, in order to prevent the air bag from being inflated and pulled out during ventilation, one or more air bag sealing structures 9 are arranged in the mold core 2. Figures 5-6 ​As shown, the upper mold 1 and the lower mold 3 are provided with a connecting part 11 on both sides of the groove; the upper mold 1 and the lower mold 3 are matched with each other through the respective connecting part 11, so that the upper mold 1 and the lower mold 3 are successfully spliced.

[0049] In some embodiments, the upper end of the upper mold 1 is further provided with a glue overflow storage groove 12.

[0050] In some embodiments, the mold core 2 is 3D printed, which is generally a small volume shell, so it is very cost-saving, and the price can be several times or even dozens of times lower than that of a machined part.

[0051] The disclosure also discloses a manufacturing method of the external support type air bag type flexible clamp, as shown in the accompanying drawings, which specifically comprises the following steps. Figures 10-11 As shown, specifically comprising:

[0052] S101, glue is injected into the glue injection hole in the manufacturing mold, and the glue injection is stopped after no bubbles appear in the glue outlet hole and the glue overflow ring hole;

[0053] S102, after the glue in the manufacturing mold is completely cured, the upper mold and the lower mold are separated, and the mold core directly serves as the shell of the external support type air bag type flexible clamp;

[0054] S103, the glue injection plug is unscrewed, and the air pipe joint is screwed into the corresponding position to obtain the external support type air bag type flexible clamp.

[0055] In some embodiments, before S101 is performed, first, the upper mold 1 and the lower mold 3 are respectively inserted into the mold core (shell) 2 from the top and the bottom, and are limited by the corresponding fixed positions; then the glue injection head is screwed into the mold core 2, and then the mold cleaning hole 7 in the lower mold 3 is tightened with a screw of a corresponding size; finally, the glue injection head is inserted into the glue injection hole 6 and ensured to be completely inserted.

[0056] In some embodiments, the glue injection operation is generally performed by using a glue injection machine.

[0057] In some embodiments, after no bubbles appear in the glue outlet hole 5 and the glue overflow ring hole 8, the glue injection head is pulled out and a cylindrical pin is used to block the position, and the glue in the glue overflow storage groove 12 remains in the original state.

[0058] In some embodiments, the mold is placed in a high-temperature oven for curing of the silica gel, and after the glue is completely cured (the preset time period is about one hour), a separation tool (for example, a small knife) is used to cut along the connecting part of the upper mold 2, the lower mold 3 and the mold core (shell) 2, the glue is separated, and then the upper mold 2 and the lower mold 3 are gently pulled out.

[0059] In some embodiments, the mold can be multi-cavity, i.e., a set of upper mold 2 and lower mold 3, and multiple mold cores 2 can be arranged side by side in the middle for simultaneous glue injection and production, and then taken out simultaneously.

[0060] In the embodiments of the present disclosure, the air bag in the air bag type flexible clamp cannot be individually disassembled or replaced, and can only be removed when the air bag reaches the end of its service life or is damaged by human factors, and then a new silica gel air bag can be made on the mold core (shell) 2 to continue to use.

[0061] In the embodiments of the present disclosure, the size of the air bag type flexible clamp produced by the integral molding process is not limited by the mounting hole position and the air bag sealing structure.

[0062] It should be noted that the mold used in the integral molding process is not limited to the upper-middle-lower structure, but can also be a surrounding or semi-surrounding structure. In the embodiments of the present disclosure, the mold core 2 is directly used as the air bag type flexible clamp, and the integral molding of the whole machine and the mold is complementary, and no special provisions are made for the size, shape and material.

[0063] In summary, the present disclosure proposes a manufacturing mold for an air bag type flexible clamp and a manufacturing method thereof, which does not require the use of parts assembly, the mold core is directly used as the shell of the air bag type flexible clamp, and the glue is directly injected into the mold core for integral molding, which is compact in structure, saves time and effort; the mold core is 3D printed, which saves cost; at the same time, once the air bag is damaged, the entire air bag can be torn off and reused as a mold core for glue injection production, which saves resources and cost and is convenient and fast.

[0064] It should be understood that the above specific embodiments of the present disclosure are only used for illustrative or explanatory purposes of the principles of the present disclosure, and do not constitute a limitation on the present disclosure. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present disclosure shall be included in the protection scope of the present disclosure.
