The thimble 207 is T-shaped, the tip of the thimble upwards penetrates through the movable block 206, the lower part of the thimble 207 is tightly attached to the movable block 206, the spring 205 is arranged at the lower part of the thimble, and the thimble 207 and the movable block 206 are simultaneously jacked up by the spring 205. Thimble 207 top sets up to the button head, and the pushing down of thimble when making things convenient for stripper 107 to push down, and the design of button head can be better bear stripper 107 and push down the impact that comes, and the movable block plays the direction to the thimble and holds up the effect in material area, makes things convenient for the material to take the removal.
The spring 205 is to be ensured to simultaneously jack up the movable block 206 and the thimble 207, the spring 205 is arranged inside the cavity plate 108 of the mold, and the spring 205 can be arranged in the cavity plate 108 by arranging holes, so as to limit and accommodate the spring 205.
The bearing comprises a bearing A202 and a bearing B203, wherein the right side of the bearing A202 exceeds the left end of the groove of the pull rod 204, and the left side of the bearing B203 exceeds the right end of the groove of the pull rod 204. Due to the design, the pull rod 204 can be prevented from directly contacting the surface of the sliding block 201 during the up-and-down movement, the friction force is reduced, and meanwhile, the sliding distance of the sliding block 201 is inaccurate due to the fact that the sliding block 201 and the pull rod 204 are prevented from being abraded due to mutual friction, and finally the feeding distance is influenced.
The mounting height of the bearing A202 on the sliding block 201 is higher than that of the bearing B203, and the bearing A202 is lower than the upper surface of the sliding block 201, so that the design ensures that the bearing A202 is firstly contacted with the inclined surface of the pull rod 204 when being pressed down, the sliding block 201 can be more smoothly pushed to the right, and the feeding function is realized.
The right side of the lower end of the pull rod 204 is provided with a bulge, and two side surfaces of the pull rod are provided with inclined surfaces, and the principle is that the two sides of the pull rod 204 are provided with bulges at different positions, so that the slide block 201 is pushed to slide along with the up-and-down movement of the die casting machine; the left side of the upper end of the pull rod 204 is also provided with an inclined surface, and the inclined surface arranged on the pull rod 204 can ensure that the pull rod 204 runs more smoothly in the pull rod 204 groove in the sliding block 201.
The upper part of the pull rod 204 is fixed on the upper backing plate 104 of the die, and the middle part passes through the fixing plate 105, the limiting plate 106 and the discharging plate 107. The lower portion of the pull rod 204 is located between the lower bolster 109 and the lower die base 110 when the pull rod 204 is pressed down, so that corresponding holes are provided in the lower bolster 109 and the lower die base 110 for receiving the lower portion of the pull rod 204.
The depth of the recess in which the movable block 206 is disposed is greater than the height of the movable block 206, so that the movable block 206 can be completely recessed into the recess when the discharge plate 107 is depressed, and the thimble 207 also needs to be located completely below the upper surface of the slider 201.
The portion of the left side of the movable block 206 beyond the cavity plate 108 is set to be an inclined surface, which facilitates the forward movement of the material. The middle position of the die is a stamping station 7 of the die.
As shown in fig. 4, two feeding mechanisms 2 are generally arranged in the mold, and the material belt 3 is located between the two feeding mechanisms 2, that is, the material belt 3 is located on the center line of a group of automatic feeding mechanisms 2, and the material belt 3 is moved by the automatic feeding mechanisms. The material belt holes 301 are located on two sides of the material belt 3, and the two feeding mechanisms 2 are matched to realize a feeding function.
One side of the automatic feeding mechanism, which is provided with the ejector pin, is arranged close to the central line of the die-casting die. Four automatic feeding mechanisms are arranged in the die, the two automatic feeding mechanisms form a group of feeding mechanisms, and a group of feeding mechanisms are respectively arranged at an inlet and an outlet in the die. One group at the inlet plays a feeding role, the other group at the outlet plays a discharging role, and the feeding mechanism can stably and accurately ensure the movement of the material belt, so that automatic feeding is realized.
The material belt is positioned on the central line of one group of automatic feeding mechanisms, and the central lines of the two groups of automatic feeding mechanisms are superposed. The ejector pin of the automatic feeding mechanism corresponds to the material belt hole of the material belt. The material area is fixed the shield cover in the intermediate position, and even interval is arranged on the material area, controls the material loading that realizes the shield cover through advancing of feeding mechanism to the material area, improves machining efficiency, and this feed mechanism compares in traditional shield cover feed mechanism, fish tail between the shield cover when having avoided material loading, conveying. Due to the existence of the material belt, oil stain residue caused by adhesion of the shielding cover in cleaning and the influence on subsequent processing are avoided; meanwhile, the material belt avoids mutual scratch between the shielding cases in the processing and cleaning processes. The yield is greatly improved, and the yield is improved to more than 90% from the original 80%.
A group of side guide plates 4 are respectively arranged at an inlet and an outlet in the die, and the arrangement of the side guide plates 4 can reduce the swing amplitude of the strip to an acceptable range because the strip can swing in the stamping process.
The material lifting nail 5 is arranged in the die, the material lifting nail 5 is used for lifting the strip material to a certain height in the feeding process, friction with the concave die plate does not occur, feeding is facilitated, the principle of the material lifting nail 5 is consistent with that of the ejector pin, and only the material lifting nail 5 is used for lifting the strip material away from the concave die plate.
The working principle is as follows: the left and right movement of the sliding block is realized by utilizing the bulges at different positions on two sides of the pull rod, the spring is matched with the movable block and the ejector pin, the ejector pin and the movable block are both pressed down when the stripper plate is pressed down, the ejector pin is separated from a material belt hole on the material belt at the moment, and the ejector pin is also bounced when the stripper plate moves up to enter the material belt hole on the material belt. The pull rod is fixed on the top plate and moves in accordance with the upper die sleeve plate, so that the pull rod moves upwards, the ejector pin is ejected, the protrusion on the right side of the lower part of the pull rod enables the sliding block to move rightwards, and the ejector pin drives the material belt to move rightwards, so that feeding is completed; the pull rod moves downwards, the ejector pins are separated, punching is conducted at the moment, meanwhile, the left side protrusion (combined with the pull rod to form an integral structure) on the upper portion of the pull rod drives the sliding block to move left, the ejector pins are separated from the material belt at the moment, the material belt is fixed in the die by the pressure of punching, the position of the material belt is unchanged, the ejector pins move to the position of the next material belt hole, punching is completed, the pull rod moves upwards, the ejector pins pop out the process of repeated feeding, and the feeding function is completed in such a circulating mode.
