Technical Field

[0001] The utility model belongs to the technical field of feeder clamps, in particular to a bushing feeder clamp. Background Art

[0002] Rubber bushings have become an indispensable component in automobiles due to their good vibration isolation, good elasticity and attenuation properties. They are usually used in automobile suspension to ensure that the entire vehicle has good operating stability and smoothness.

[0003] After the half mold is closed, the rubber bushings cannot be placed into the mold cavity, and conventional feeders cannot be used to add material. During operation, workers pull the half mold apart and manually hang the rubber bushings on the mold cavity one by one before closing the mold for vulcanization. This process takes a long time, and wearing thin gloves can easily burn fingers. At the same time, the vibration generated when the half mold is closed can easily cause the rubber bushings to vibrate off the mold cavity. Utility Model Content

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] Example 1

[0019] like Figure 1 、 Figure 2 and Figure 3 As shown, the bushing feeder fixture includes a heat-resistant plate 1 and a slide bar 2. The heat-resistant plate 1 is made of any one of aliphatic nylon - PA46, polyether ketone, etc. There are at least four heat-resistant plates 1, and the two heat-resistant plates 1 located at the outermost edges are fixedly connected with handles 3. There are at least three slide bars 2. The two ends of the bushing are large and the middle is small, and the inner wall is provided with metal parts. The heat-resistant plate 1 is connected to the slide bar 2 through an adjustment mechanism. The adjustment mechanism can adjust the spacing between multiple heat-resistant plates 1 to adapt to Hough molds of different specifications. The heat-resistant plate 1 is installed with multiple positioning pins 5, and each positioning pin 5 is provided with a plurality of strong magnets 6 in a ring array. The strong magnets 6 are fixedly connected to the positioning pins 5 and are adsorbed and matched with the metal parts of the bushing.

[0020] It should be noted that aliphatic nylon - PA46 is an aliphatic polyamide formed by the condensation of butanediamine and adipic acid. Compared with PA6 and PA66, PA46 has more amides on each given chain length and a more symmetrical chain structure, which makes its crystallinity as high as 70% and gives it a very fast crystallization rate. The melting point of PA46 is 295℃, and the HDT (heat deformation temperature) of unreinforced PA46 is 160℃. After being reinforced with glass fiber, its HDT can be as high as 290℃, and the long-term use temperature is also 163℃; polyetherketone is abbreviated as PEK. Since the ratio of ether bonds and ketone groups in its molecular structure is lower than that of PEEK, its melting point and glass transition temperature are higher than PEEK, and its heat resistance is better than PEEK, with a continuous use temperature of 250℃.

[0021] Specifically, the position of the heat-resistant plate 1 is adjusted through the adjustment mechanism so that multiple positioning pins 5 can adapt to different specifications of half molds. Then the bushing is assembled onto the positioning pin 5. The strong magnet 6 is adsorbed and matched with the metal parts in the bushing to increase the stability of the bushing. Then the half mold can be opened, and the worker uses the handle 3 to carry multiple assembled bushings and place them in the cavity of the half mold. At this time, the half mold can be closed, and the handle 3 can be pulled to pull out the positioning pin 5, and the bushing can be vulcanized.

[0022] like Figure 2 and Figure 3 As shown, one end of the locating pin 5 is fixedly connected to a threaded rod 8, the threaded rod 8 is threadedly connected to a second hexagonal nut 9, the heat-resistant plate 1 is provided with a placement hole, the locating pin 5 is movably sleeved in the placement hole, and the side wall of the locating pin 5 is fixedly connected to a baffle, and the second hexagonal nut 9 and the baffle are respectively located on both sides of the heat-resistant plate 1.

[0023] It should be noted that the length of the baffle is greater than the diameter of the placement hole, so that the positioning pin 5 cannot completely pass through the placement hole. The positioning pin 5 can be removed from the heat-resistant plate 1 through the threaded cooperation between the threaded rod 8 and the second hexagonal nut 9.

[0024] like Figure 3 As shown, the end of the positioning pin 5 away from the threaded rod 8 is a conical boss, and the outer ring is provided with a non-slip rubber sleeve.

[0025] It should be noted that the bushing is conveniently put on the outer ring of the positioning pin 5 from the conical boss, and the friction can be increased by the anti-slip rubber sleeve to prevent the bushing from sliding off the outer ring of the positioning pin 5 due to its own gravity.

[0026] Example 2

[0027] like Figure 1 、 Figure 2 and Figure 3As shown, the bushing feeder fixture, compared with Example 1, the adjustment mechanism of this embodiment includes a slide rod 7, the slide rod 7 is "T"-shaped, and a first groove and a second groove are concentrically arranged on both sides of the heat-resistant plate 1. The first groove and the second groove are interconnected, and the combination of the first groove and the second groove is "T"-shaped. The big head of the slide rod 7 is located in the first groove, and the small head passes through the second groove, and is threadedly connected with a first hexagonal nut 4.

[0028] like Figure 3 As shown, the slide bar 2 is provided with a plurality of slide openings 21 , the small end of the slide rod 7 passes through the slide openings 21 , and the slide bar 2 is located between the heat-resistant plate 1 and the first hexagonal nut 4 .

[0029] Specifically, rotate the first hexagonal nut 4. When the first hexagonal nuts 4 on the same heat-resistant plate 1 are away from the sliding bar 2, the heat-resistant plate 1 can be pulled to slide on the sliding bar 2, so that the distance between the two heat-resistant plates 1 can be adjusted. When the position of the heat-resistant plate 1 is adjusted, rotate the first hexagonal nut 4 in the opposite direction so that it fits tightly with the sliding bar 2 to prevent the heat-resistant plate 1 from sliding.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
