[0051] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0052] Combine the following Figures 1 to 7 , describing an embodiment of the utility model.
[0053] According to an embodiment of the present utility model, on the one hand, a fixture is provided, comprising:
[0054] Base 10;
[0055] The positioning base 20 is fixedly disposed on the base 10. The side of the positioning base 20 away from the base 10 in the height direction is suitable for positioning the product 50. The positioning base 20 is provided with a plurality of first through holes 201 and a plurality of second through holes 202 in the height direction.
[0056] The ejector assembly 30 is coaxially arranged with the first through hole 201, and the ejector assembly 30 is suitable for extending from the first through hole 201 and ejecting the product 50 from the positioning base 20;
[0057] The adsorption component 40 is coaxially arranged with the second through hole 202 , and is suitable for adsorbing the product 50 during the molding and pressing process and / or the process in which the ejection component 30 ejects the product from the positioning base 20 .
[0058] The jig provided in this embodiment is provided with an ejector assembly 30. When the hardware and the plastic middle frame are molded and pressed together on the positioning base 20, a plurality of ejector assemblies 30 are synchronously extended from the first through hole 201, thereby smoothly ejecting the product from the positioning base 20. Compared with the demoulding method of manually removing the product from the positioning base, it not only reduces the difficulty of operation, but also helps to reduce the incidence of three damages of the product; by providing an adsorption assembly 40, on the one hand, the plastic middle frame can be adsorbed by the adsorption assembly 40 before the hardware and the plastic middle frame are molded and pressed together. The plastic middle frame can be adsorbed (if the plastic middle frame is tilted or offset, negative pressure cannot be formed between the adsorption component 40 and the wall of the plastic middle frame due to the gap, resulting in failure to attract), so as to pre-position the plastic middle frame, which is beneficial to ensure the alignment of the hardware and the plastic middle frame. On the other hand, the adsorption component 40 can adsorb the product during the process of the ejection component 30 ejecting the product from the positioning base 20, so that the product maintains and / or tends to a balanced state, thereby preventing the product from being ejected out of control due to the ejection force after demoulding, and effectively avoiding product collision and causing three injuries.
[0059] In some embodiments, please combine Figure 2 and Figure 4 As shown, each ejection assembly 30 includes a push rod 31 and a cylinder 32; the push rod 31 is movably arranged in the first through hole 201, and one end of the push rod 31 in the height direction is suitable for abutting against the load-bearing bone position of the product; the cylinder 32 is fixedly arranged on the side of the positioning base 20 away from the product in the height direction, and the cylinder 32 is fixedly connected to the other end of the push rod 31 in the height direction, and the cylinder 32 is suitable for driving the push rod 31 to move in the first through hole 201 along the height direction; when the hardware and the plastic middle frame are completed on the positioning base 20. After the plastic pressing is completed, the cylinder 32 synchronously drives the push rod 31, so that the push rod 31 is synchronously extended in the first through hole 201 along the height direction and synchronously abuts against the load-bearing bone position of the product, so that the product is smoothly demolded from the positioning base 20, which is not only beneficial to reduce the incidence of three damages of the product, but also beneficial to reduce the difficulty of taking and placing this process, so as to facilitate the operation of the robot, thereby improving production efficiency.
[0060] It should be noted that the load-bearing bone position of the product refers to the place where the product bone strength is higher selected as the ejection point, and the ejection point is suitable for abutting against the ejector rod 31, wherein the load-bearing bone position is located on the plastic middle frame. After the hardware and the plastic middle frame are molded and pressed on the positioning base 20 to form the product, the product is ejected by the ejection assembly 30. Since the hardware and the plastic middle frame have not yet completely cooled and solidified, if the load-bearing bone position is determined on the hardware, it is easy to cause the plastic middle frame to separate from the hardware, causing the plastic middle frame to remain in the positioning base 20. Therefore, it is necessary to determine the load-bearing bone position on the plastic middle frame, so that the plastic middle frame can lift the load-bearing bone position of the plastic middle frame and carry the hardware to rise and demold together.
[0061] In some embodiments, see Figure 4 As shown, the cylinder 32 includes a cylinder barrel 321, a piston body 322 and a piston rod 323; the piston body 322 is movably arranged in the cylinder barrel 321; one end of the piston rod 323 in the height direction is fixedly connected to the piston body 322, and the other end is threadedly connected to the push rod 31; on the one hand, after the hardware and the plastic middle frame are molded and pressed on the positioning base 20, the piston rod 323, driven by the piston body 322, drives the push rod 31 to synchronously extend in the height direction in the first through hole 201 and synchronously push against the load-bearing bone position of the product, so that the product can be smoothly demolded from the positioning base 20. On the other hand, the piston rod 323 is threadedly connected to the push rod 31, so as to facilitate the adjustment of the lifting height of each push rod 31, so that the push force of the push rod 31 on the product is more uniform.
[0062] In some embodiments, please combine Figure 3 and Figure 5 As shown, the adsorption component 40 includes a suction cup 41 and a vacuum tube 42; the suction cup 41 is built into the second through hole 202, and the suction cup 41 is suitable for adsorbing the side wall of the product; the vacuum tube 42 is fixedly arranged at one end of the suction cup 41 away from the product in the height direction; the vacuum tube 42 is connected to the suction cup 41, and the vacuum tube 42 is suitable for vacuuming the suction cup 41 so that the suction cup 41 adsorbs the product; in the molding and pressing process, the suction cup 41 is vacuumed by the vacuum tube 42, so that the suction cup 41 adsorbs the product, thereby positioning the product, which is beneficial to ensure the alignment of the hardware and the plastic middle frame; in the process of the ejection component 30 ejecting the product from the positioning base 20, the suction cup 41 is vacuumed by the vacuum tube 42, so that the suction cup 41 adsorbs the product, thereby preventing the product from being ejected out of control due to the ejection force after demolding, and effectively avoiding the collision of the product and causing three injuries.
[0063] Furthermore, one end of the vacuum tube 42 away from the suction cup 41 may be connected to an external vacuum system.

[0065] A spring 44 is provided at one end of each vacuum tube 42 away from the suction cup 41 in the height direction. The spring 44 is coaxially arranged with the vacuum tube 42. One end of the spring 44 in the height direction is connected to the vacuum tube 42, and the other end is in contact with the base 10. The spring 44 is suitable for resetting the suction cup 41 after the suction cup 41 is separated from the product.
[0066] By providing the sleeve 43, the vacuum tube 42 can slide back and forth in the height direction relative to the sleeve 43; by providing the spring 44, in the process of the ejection assembly 30 ejecting the product from the positioning base 20, the tension of the spring 44 and the adsorption force of the suction cup 41 can reach a balanced state with the resisting force of the ejection assembly 30, thereby preventing the product from being ejected out of control due to the ejection force after demoulding, and effectively avoiding the three injuries caused by product collision; when the product is demoulded, the suction cup 41 can be reset by the elastic restoring force of the spring 44.
[0067] In some embodiments, see Figure 5 As shown, a first limiting portion 421 is provided at one end of the vacuum tube 42 close to the suction cup 41 in the height direction, and the first limiting portion 421 is built in the second through hole 202, and the first limiting portion 421 is suitable for abutting against the sleeve 43; when the product is demolded, the suction cup 41 and the vacuum tube 42 shrink in the height direction in the second through hole 202 under the action of the elastic restoring force of the spring 44, and abut against the shoulder of the sleeve 43 through the first limiting portion 421, so that the suction cup 41 and the vacuum tube 42 remain in the initial state.
[0068] In some embodiments, see Figure 5 As shown, an adapter 45 is provided at one end of the vacuum tube 42 away from the suction cup 41 in the height direction, and the adapter 45 is threadedly connected to the vacuum tube 42, and the adapter 45 is suitable for connecting the vacuum tube 42 with an external vacuum system; a second limiting portion 451 is provided on the adapter 45, and the second limiting portion 451 is suitable for abutting against the spring 44; by setting the second limiting portion 451, during the process of threaded connection between the adapter 45 and the vacuum tube 42, the spring 44 is limited and / or pre-compressed, and then the suction cup 41 is reset by the spring 44.
[0069] In some embodiments, please combine Figure 6 and Figure 7As shown, a plurality of ejection assemblies 30 are symmetrically arranged on the positioning base 20, and one end of each ejection assembly 30 in the height direction abuts against the load-bearing bone of the product, so that the product is evenly stressed during the ejection process, preventing the film from being pulled at a certain point of the product and causing poor flatness of the product.
[0070] For further information, see Figure 7 As shown, the large side of the product can be divided into six equal areas, and the places with higher bone strength of the product can be found in each of the six areas and selected as the ejection points, so that the product is evenly stressed during the ejection process, preventing the film from being pulled at a certain point of the product, resulting in poor flatness of the product.

This can prevent the film from being pulled at a certain point of the product and resulting in poor flatness of the product, and can also prevent the product from being ejected out of control due to the ejection force after demolding, effectively avoiding three injuries caused by product collision.
[0072] For further information, see Figure 7 As shown, the large side of the product can be equally divided into four areas, and an adsorption component 40 is respectively arranged in each of the four areas.
