Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotational molding technology, and more specifically, to an adjustable rotational molding positioning device. Background Technology
[0002] Rotational molding molds are used to make plastic container products. They are usually divided into upper molds and lower molds. The plastic products are processed and manufactured by closing the upper and lower molds.
[0003] However, when the existing upper mold is closed with the lower mold, it is directly lowered without any limiting or positioning structure. This makes it easy for deviations to occur when the upper mold is lowered, resulting in the upper and lower molds not fitting together tightly. Utility Model Content
[0004] The purpose of this invention is to provide an adjustable rotational molding die positioning device, which solves the problem that when the upper die of a rotational molding die is lowered, errors and misalignments are easily generated at the fitting point, which affects the molding process.
[0005] This utility model is achieved through the following technical solution:
[0006] This utility model provides an adjustable rotational molding die positioning device, including a die, an upper die connected to the top of the die, a base connected to the bottom of the die, a connecting groove provided at the top of the base, sliding grooves provided on both sides of the middle of the connecting groove, a positioning rod connected to the middle of the connecting groove, sliding rods provided on both sides of one end of the positioning rod, an interlocking groove provided at the bottom of the connecting groove, a limit component connected to one end of the interlocking groove, and the limit component moving along the interlocking groove.
[0007] Preferably, the sliding groove is matched with the sliding rod.
[0008] Preferably, the positioning rod also includes a contact surface, which is disposed on one side of one end of the positioning rod and is a parallel surface to one side of the arc end of the positioning rod.
[0009] Preferably, the fitting groove is a groove at the bottom of the middle part of the sliding groove.
[0010] Preferably, the limiting component includes a displacement screw and a limiting block, with the displacement screw connected to the middle of the fitting groove and the limiting block connected to one end of the fitting groove.
[0011] Preferably, one end of the displacement screw is connected through the limiting block.
[0012] Preferably, the top of the limiting block is also provided with a protrusion that mates with the connecting groove, and the inner wall of the through hole of the limiting block matches the thread of the displacement screw.
[0013] The technical solution of this utility model has at least the following advantages and beneficial effects:
[0014] 1. The positioning rod in this device can be displaced according to the size of different molds, and then deflected and erected by applying force, thereby forming a guide rod that fits against the side wall of the mold to limit and position the lowering of the upper mold, so as to facilitate better mold closing. At the same time, the deflection setting of the positioning rod can also facilitate the replacement of the lower mold.
[0015] 2. The device is also equipped with a limiting component. When the positioning rod deflects and abuts against the side wall of the mold, the limiting component can be controlled to move and then fit against one side of the positioning rod to limit the positioning rod and prevent the positioning rod from deflecting on its own.

[0020] The following is combined Figures 1 to 3 This utility model will be described in detail.
[0021] An adjustable rotational molding die positioning device includes a die 1, an upper die 2 connected to the top of the die 1, a base 3 connected to the bottom of the die 1, a connecting groove 301 provided on the top of the base 3, sliding grooves 3011 provided on both sides of the middle of the connecting groove 301, a positioning rod 302 connected to the middle of the connecting groove 301, sliding rods 3021 provided on both sides of one end of the positioning rod 302, and a fitting groove 3012 provided at the bottom of the connecting groove 301. A limiting component is connected to one end of the fitting groove 3012, and the limiting component moves along the fitting groove 3012.
[0022] First, mold 1 is placed on base 3, and then the material between upper mold 2 and mold 1 is formed by closing upper mold 2 and mold 1.
[0023] Furthermore, the sliding groove 3011 cooperates with the sliding rod 3021, and the positioning rod 302 also includes an abutment surface 3022. The abutment surface 3022 is disposed on one side of one end of the positioning rod 302, and the abutment surface 3022 is a parallel surface on one side of the arc end of the positioning rod 302.
[0024] After the mold 1 is placed on the base 3, the positioning rod 302 is pulled to move along the fitting groove 3012. When it moves to the edge of the mold 1, the positioning rod 302 is forced to deflect and stand upright along the sliding groove 3011 via the sliding rod 3021 at one end, so that it stands upright against the side wall of the mold 1, thereby forming a positioning rod to facilitate the lowering of the upper mold 2.
[0025] Furthermore, the fitting groove 3012 is a groove at the bottom of the middle part of the sliding groove 3011. The limiting component includes a displacement screw 3013 and a limiting block 303. The displacement screw 3013 is connected to the middle part of the fitting groove 3012, and the limiting block 303 is connected to one end of the fitting groove 3012. One end of the displacement screw 3013 passes through the limiting block 303 for connection. The top of the limiting block 303 is also provided with a protrusion that cooperates with the connecting groove 301, and the inner wall of the through hole of the limiting block 303 is threadedly matched with the displacement screw 3013.
[0026] Then, after the positioning rod 302 is moved to the appropriate position and erected, the displacement screw 3013 is rotated to allow the limiting block 303 to move along the fitting groove 3012, thereby causing the protrusion of the top mating connecting groove 301 to also move until it moves to one side of the positioning rod 302 and abuts against it, thereby limiting the positioning rod 302 and preventing it from deflecting and resetting. At the same time, the abutting surface 3022 of the arc end face of the positioning rod 302 can prevent the positioning rod 302 from deflecting to the other side after it is erected. In this way, through cooperation with the limiting block 303, the positioning rod 302 can maintain its upright state and fit against the side wall of the mold 1. Then, the part protruding from the top of the mold 1 will form a guide rod that limits and positions the upper mold 2, which facilitates mold closing.
[0027] The following is a detailed implementation process of this utility model: First, mold 1 is placed on base 3. Then, the upper mold 2 and mold 1 are closed to allow the raw material between them to be formed. After mold 1 is placed on base 3, the positioning rod 302 is pulled to move along the fitting groove 3012. When it moves to the edge of mold 1, force is applied to the positioning rod 302, causing it to deflect and stand upright along the sliding groove 3011 via the sliding rod 3021 at one end, so that it stands upright against the side wall of mold 1, thus forming a positioning rod to facilitate the lowering of the upper mold 2. After the positioning rod 302 moves to the appropriate position and stands upright, it is controlled by... The displacement screw 3013 rotates to move the limiting block 303 along the fitting groove 3012, thereby moving the protrusion of the top mating connecting groove 301 until it moves to one side of the positioning rod 302 and abuts against it, thus limiting the positioning rod 302 and preventing it from deflecting and returning to its original position. At the same time, the abutting surface 3022 of the arc end face of the positioning rod 302 can prevent the positioning rod 302 from deflecting to the other side after it is erected. In this way, through cooperation with the limiting block 303, the positioning rod 302 can be kept in an upright state and fit against the side wall of the mold 1. Then, the part protruding from the top of the mold 1 will form a guide rod for limiting and positioning the upper mold 2, which facilitates mold closing.
