Abstract
Description
Technical Field
[0001] The invention belongs to the field of mold clamping equipment manufacturing, and in particular relates to a material clamping device. Background Art
[0002] In the prior art, when the mold is forming the raw materials, the clamping mechanism on the mold is required to clamp the raw materials. The traditional clamping mechanism can only grab the raw materials outside the mold core and cannot properly stretch the materials. This requires that the raw materials must protrude from the mold core before they can be clamped by the clamping mechanism. This protruding part invisibly increases the raw material cost of the merchant, which is not conducive to the long-term development of the enterprise. Summary of the invention
[0003] In view of the defects existing in the prior art, the present invention aims to provide a material clamping device, which can extend into the interior of the mold to clamp the raw material, and can appropriately stretch the raw material after grabbing it, so as to facilitate the mold to perform molding operations on the raw material.
[0004] The technical solution provided by the present invention is: a material clamping device, including a base, a bracket plate located on the base, a clamping mechanism and a positioning device, the front end of the bracket plate is movably connected to the base through a spring, the rear end of the bracket plate is fixedly connected to the base, the clamping mechanism is located above the bracket plate and fixedly connected to the rear side of the bracket plate, the positioning device is located below the clamping mechanism and fixedly connected to the front side of the bracket plate; it also includes a stretching device for stretching materials, one end of the stretching device is fixedly connected to the bracket plate, and the other end is hinged to the base.
[0005] The above scheme is further improved and optimized: the bracket plate includes a mounting plate, a horizontal plate and a vertical plate, the mounting plate is fixedly connected to the base and is arranged in pairs on both sides of the horizontal plate, a mounting hole is opened on the mounting plate, a rotating shaft is fixed in the mounting hole, the horizontal plate is mounted on the rotating shaft and abuts against the rotating shaft, one end of the horizontal plate parallel to the rotating shaft is fixedly connected to the base by a bolt, and the other end of the horizontal plate parallel to the rotating shaft is fixedly connected to the base by a spring, a positioning bolt is inserted into the spring, the upper part of the positioning bolt is fixedly connected to the horizontal plate, and the lower part of the positioning bolt is spaced from the base; the vertical plate is vertically fixed to the horizontal plate; an oblique reinforcing rib plate is also fixed between the vertical plate and the horizontal plate.
[0006] The above scheme is further improved and optimized: the clamping mechanism includes an upper clamping plate, a lower clamping plate and a flipping device for driving the upper clamping plate to rotate, a connecting block is fixed at the middle position of the tail end of the upper clamping plate, a rotating block is fixed to the tail end of the lower clamping plate, the upper end of the rotating block is hinged to the connecting block, and the lower end of the rotating block is hinged to the flipping device through a U-shaped connecting plate. Specifically, the upper end of the U-shaped connecting plate is hinged to the lower end of the rotating block, and the lower end of the U-shaped connecting plate is fixedly connected to the top of the flipping device; a vertical mounting plate is fixed to the side of the lower end surface of the lower clamping plate close to the connecting block, and both sides of the vertical mounting plate are fixedly connected to the vertical plate through a bolt structure.
[0007] The above scheme is further improved and optimized: a buffer horizontal plate is fixed to one side of the vertical plate, one end of the buffer horizontal plate is fixedly connected to the vertical plate, and the other end is overlapped on the L-shaped support column, and the L-shaped support column is fixedly connected to the base. When the stretching device is in the initial state, the buffer horizontal plate overlaps the L-shaped support column. When the stretching device is in the return process, the vertical plate will rebound in the direction of the stretching device due to the reaction of the spring. The buffer horizontal plate limits its rebound movement and also plays a buffering role to avoid excessive rebound and damage to the raw materials.
[0008] The above scheme is further improved and optimized: the flipping device is a flipping cylinder, the upper end of the flipping cylinder is fixedly connected to the bottom end of the U-shaped connecting plate, and the lower end of the flipping cylinder is fixedly connected to the lower part of the vertical mounting plate. The flipping device is used to drive the flipping of the upper clamping plate, so as to achieve the effect of sealing and separation with the lower clamping plate. In the sealed state, the raw material is clamped and stretched under the action of the stretching device.
[0009] The above scheme is further improved and optimized: a plurality of short cone pins are fixed on the side of the upper clamping plate close to the lower clamping plate, and a pin hole corresponding to the short cone pins is opened on the lower clamping plate; a plurality of upper clamping blocks are fixed on the upper edge side of the upper clamping plate, and a gap is left between the upper clamping blocks; a plurality of lower clamping blocks are fixed on the side of the lower clamping plate close to the upper clamping plate, and a gap is left between the lower clamping blocks, and the upper clamping blocks and the lower clamping blocks are clamped in a copper drum interval. Specifically, the upper clamping blocks are filled in the gaps of the lower clamping blocks, and the lower clamping blocks are filled in the gaps of the upper clamping blocks to achieve a close fit.
[0010] The above scheme is further improved and optimized: the positioning devices are arranged in pairs on both sides of the lower clamping plate, and are fixedly connected to the lower end face of the lower clamping plate through the vertical side plate, and the side of the vertical side plate close to the positioning device is provided with an upper protrusion and a lower protrusion; the positioning device includes a long cone positioning pin and a lifting cylinder driving the long cone positioning pin to move up and down, the lifting cylinder and the long cone positioning pin are fixedly connected through a pin block, the pin block overlaps the upper protrusion, and the upper and lower ends of the lifting cylinder are respectively fixedly connected to the front end face of the upper protrusion and the front end face of the lower protrusion through an L-shaped connecting plate; the lower clamping plate is provided with a pin hole corresponding to the long cone positioning pin; an oblique reinforcing plate is also fixed between the vertical side plate and the lower clamping plate. The long cone positioning pin in the positioning device is used to pass through the raw material and position the raw material, so that the upper clamping plate and the lower clamping plate can clamp the raw material.
[0011] The above scheme is further improved and optimized: the stretching device is a stretching cylinder, which is fixedly connected to the vertical plate through a horizontal fixing plate, and the horizontal fixing plates are arranged in pairs on both sides of the vertical plate. A circular through hole is opened on the end of the horizontal fixing plate close to the stretching cylinder, and a fixed shaft passes through the circular through holes. The top of the stretching cylinder is fixedly connected to the fixed shaft, and the bottom of the stretching cylinder is hinged to the fixing seat through the lower U-shaped connecting plate, and the fixing seat is fixedly connected to the base. The stretching device allows the clamping mechanism and the positioning device to enter the mold core to clamp the raw materials, and stretch the raw materials until the outside of the mold core, so that the mold can perform molding operations on the raw materials.
[0012] Compared with the prior art, the beneficial effects brought by the present invention are as follows: the traditional clamping mechanism can only clamp the raw materials, and clamp them outside the mold core, so it is necessary to increase the clamping area on the molded raw materials, which invisibly increases the raw material costs of the merchants. The present invention adds a stretching device, which can penetrate into the mold core to stretch the raw materials, thus avoiding the original increased clamping area, saving the raw material costs of the merchants and improving production efficiency.
