Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of glue injection treatment, and particularly relates to a glue injection mold rubber plug pulling device. Background Technique
[0002] Glue injection is a conventional processing technology for glue material products. It is to inject fluid glue into a glue injection mold, and a product is formed after the glue solidifies; for example, many plastic products and rubber products (sealing rings, rubber rings, etc.). Also, for example, many current electronic products (the back side of the screen) need to be provided with a sealing rubber ring. The traditional process of setting the rubber ring on the back side of the display screen is to use a dispensing machine to dispense glue on the back side of the product. However, due to the dispensing process, there will be an interface, which affects the overall quality. Therefore, currently, the glue injection method is used to form a rubber ring on the back side of the product. Specifically, the product is positioned in the glue injection mold, and the glue is squeezed into the glue injection mold by a glue injection machine, so as to form a rubber ring on the product. After curing, the whole product can be taken out.
[0003] For example, a glue injection and curing process disclosed in the Chinese patent document with the publication number CN117038524A includes the following steps: S1: Clamp the screen assembly between the upper mold core and the lower mold core of the glue injection mold, so that the bent part of the screen assembly is hermetically arranged in the glue injection groove of the glue injection mold, and close the mold; S2: Inject glue into the glue injection mold to simultaneously fill the glue material on the inner and outer sides of the outer side wall of the bent part; S3: Cure the colloid to form a glue sealing structure on the inner and outer sides of the outer side wall of the bent part; S4: Release the mold closing, and demold the cured colloid and the screen assembly.
[0004] Since the glue will have problems such as deformation when curing after glue injection, in order to overcome the above technical defects. After glue injection, it is necessary to use a rubber plug to block the glue injection port. After blocking, the glue will be fixed to the rubber plug as a whole. Therefore, when demolding, it is necessary to take out the rubber plug from the glue injection mold and then complete the demolding of the screen assembly. Currently, to take out the rubber plug, it is generally done manually. The manual workload is large, and the force for pulling out the rubber plug cannot be controlled, which easily causes the problem of damaging the glue on the screen assembly. Content of the Utility Model
[0005] The purpose of the utility model is to provide a glue injection mold rubber plug pulling device, which solves the problems of large workload and inability to ensure the force for pulling out the rubber plug in the existing manual rubber plug pulling, resulting in damage to the glue on the screen.

[0014] The apparatus for removing a rubber plug from a glue injection mold of the present utility model has the following beneficial effects:

In addition, the clamping position of the clamping mechanism always remains consistent, and the rotating mechanism drives the clamping mechanism to rotate repeatedly, so as to ensure that the rubber plug is detached from the connection position between the rubber plug and the glue, thereby improving the quality of the injection of the screen assembly after the rubber plug is pulled out.

[0023] The following detailed embodiments will be further described in conjunction with the above drawings.
[0024] In the following text, a variety of specific details are elaborated to provide a thorough understanding of the concepts underlying the described embodiments. However, for those skilled in the art, it is obvious that the described embodiments can be practiced without some or all of these specific details. In other cases, well-known processing steps are not specifically described.
[0025] In an embodiment of the glue plug pulling device for the injection mold of the present utility model, please refer to Figures 1 to 3 ; The glue plug pulling device for the injection mold can automatically pull out the glue plugs on the injection mold, improving efficiency. Moreover, it can ensure that the breaking positions of each glue plug are consistent, improving the product quality. Specifically, the glue plug pulling device for the injection mold includes a machine table 100, a conveying line 200, a moving mechanism 300, and a positioning mechanism 400.
[0026] Among them, referring to 1 to Figure 3 , the conveying line 200 and the moving mechanism 300 are arranged on the machine table 100, and the moving mechanism 300 includes a moving end 301 located above the conveying line 200. The conveying line 200 is used to convey the injection mold 500 with molded plastic parts. The positioning mechanism 400 is arranged on one side of the conveying line 200 for positioning the injection mold 500 on the conveying line 200. The moving end 301 is provided with a rotating mechanism 600, and the rotating end of the rotating mechanism 600 is provided with a clamping mechanism 700. The clamping mechanism 700 is used for the glue plugs on the injection mold 500. The rotating mechanism 600 drives the clamping mechanism 700 to rotate, so that the clamping mechanism 700 can break the connection position between the glue plug and the injection by rotating, realizing the pulling out of the glue plug, and the pulled-out glue plug is held on the clamping mechanism 700. Specifically, the injection mold 500 after injection can be placed on the conveying line 200. The conveying line 200 conveys the injection mold 500 to the bottom end of the moving mechanism 300, and the positioning mechanism 400 positions the injection mold 500. The moving mechanism 500 drives the clamping mechanism 700 to descend, so that the clamping mechanism 700 can clamp the glue plug on the top side of the injection mold 500. Then, the rotating mechanism 600 drives the clamping mechanism 700 to rotate repeatedly, so as to break the glue plug from the connected position. Therefore, it replaces the problem of manually pulling out the glue plug, realizes automation, and improves production efficiency. In addition, the clamping position of the clamping mechanism 700 always remains consistent, and the rotating mechanism 600 drives the clamping mechanism 700 to rotate repeatedly, so as to ensure that the glue plug is separated from the position where the glue plug is connected to the glue, thereby improving the quality of the injection of the screen assembly after the glue plug is pulled out.
[0027] Preferably, a blanking port 101 is further arranged on the top side of the machine table 100, and the blanking port 101 is located on the moving track of the moving end 301. A waste channel 102 is arranged at the bottom side of the blanking port 101 for receiving the pulled-out glue plugs. Specifically, after the clamping mechanism 700 pulls out the glue plug, the clamping mechanism 700 still holds the glue plug, and under the action of the moving mechanism 300, it drives the clamping mechanism 700 to move above the blanking port 101, so that the clamping mechanism 700 can drop the pulled-out glue plug into the blanking port 101, and then the waste channel 102 collects the waste glue plugs.
[0028] Preferably, please refer to Figure 1 and Figure 2, the moving mechanism 300 includes a first translation mechanism 310, a second translation mechanism 320, and a lifting mechanism 330. The first translation mechanism 310 is provided on the machine table 100, the second translation mechanism 320 is connected to the first translation mechanism 310, and the lifting mechanism 330 is connected to the lifting mechanism 330. An installation seat 331 is provided at the lifting end of the lifting mechanism 330, and the rotating mechanism 600 is provided on the installation seat 331. Specifically, the first translation mechanism 310, the second translation mechanism 320, and the lifting mechanism 330 are all electric linear die bases. Thus, it can drive the clamping mechanism 700 to translate and lift at any position.
[0029] More preferably, referring to Figure 4 , the rotating mechanism 600 is a reduction motor provided on the installation seat 331. The reduction motor drives the clamping mechanism 700 to rotate, with stable rotation, and can control the rotation speed, enabling the clamping mechanism 700 to better break the nozzle.
[0030] Preferably, referring to Figure 4 and Figure 5 , the clamping mechanism 700 is a parallel clamp 701 provided at the rotating end of the rotating mechanism 600. Claw jaws 702 are provided on the two clamping blocks of the parallel clamp 701, and a clamping opening 703 is provided at the free end of the claw jaws 702. When the two claw jaws 702 clamp the glue injection port, the two clamping openings 703 form a clamping position, thereby realizing clamping the rubber plug. Further, the center position of the clamping position coincides with the rotation axis of the rotating mechanism 600, avoiding the problem of eccentric rotation of the clamping mechanism 700 and the problem of the clamping mechanism 700 pulling the rubber plug, resulting in an uneven fracture position at the end.
[0031] Preferably, referring to Figure 5 , a wear-resistant block 704 is further provided at the free end of the claw jaw 702, and the clamping opening 703 extends to the top of the wear-resistant block 704. Thereby increasing the wear resistance of the claw jaw 702.
[0032] Preferably, the conveyor line 200 includes two parallel circulating conveying surfaces 201, and the positioning mechanism 400 is provided between the two circulating conveying surfaces 201. When the positioning mechanism 400 positions one group of glue injection molds 500, it does not affect the normal conveying of other glue injection molds 500.
[0033] Preferably, referring to Figure 6, the positioning mechanism 400 includes a lifting mechanism 410 and a positioning lifting plate 420. The lifting mechanism 410 is arranged between the two circulating conveying surfaces 201, and the positioning lifting plate 420 is arranged at the lifting end of the lifting mechanism 410. A positioning pin 421 is arranged on the positioning lifting plate 420 for positioning the injection mold 500. When the injection mold 500 is conveyed to the top side of the positioning mechanism 400, the lifting mechanism 410 lifts the positioning lifting plate 420 upward, and the positioning pin 421 on the positioning lifting plate 420 is positioned in the positioning hole on the bottom side of the injection mold 500, so as to realize the positioning of the injection mold 500. At the same time, the injection mold 500 is lifted upward, which is convenient for the clamping mechanism 700 to clamp the rubber plug on the injection mold 500.
[0034] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
