Description

Injection molding machine with rotatable injection assembly Technical Field The utility model relates to the technical field of injection molding machines, in particular to an injection molding machine with a rotatable injection assembly. Background The injection molding machine includes an injection assembly that melts plastic particles and then inputs the melted plastic into a mold plate for molding. The injection assembly comprises a plasticizing assembly, a motor-driven screw is arranged in the plasticizing assembly, plastic particles are conveyed to the direction of the fixed template through the screw, and the plastic particles are melted into a liquid state under the action of the heating assembly. When the type and the requirement of moulding plastics need change, need change different screws, and because the screw rod during operation is hidden in the casing of plasticizing component, even after injection subassembly kept away from the fixed template, still do not have sufficient space and carry out the screw rod dismouting, consequently can dismantle whole injection subassembly earlier, then carry out the dismouting of screw rod, so work load is great, and efficiency is too low. Disclosure of utility model In order to solve the technical problems in the background art, the utility model discloses an injection molding machine with a rotatable injection assembly. The utility model provides an injection molding machine with a rotatable injection assembly, which comprises the injection assembly, wherein a front support and a rear support are respectively arranged on two sides of the lower end of the injection assembly, and a sliding block is arranged at the upper end of the front support and is in rolling connection with the front support through a rolling bearing, so that the sliding block can horizontally move, and the moving direction of the sliding block is vertical to the moving direction of the injection assembly; the sliding block and the rear support are provided with a rotating bearing; The front rotating shaft and the rear rotating shaft are respectively arranged at the front end and the rear end of the lower side of the injection assembly and are inserted into the rotating bearing; a plasticizing assembly is arranged at one end of the injection assembly, which is close to the fixed template, and a motor-driven screw is arranged in the plasticizing assembly; the screw is deviated from the fixed die plate by horizontally moving and rotating one end of the injection assembly close to the fixed die plate. When the screw rod in the plasticizing assembly needs to be replaced, the injection assembly is moved to be separated from and far away from the fixed template, and then the outlet part of the injection assembly is rotated, and when the injection assembly is rotated, the sliding block moves along with the injection assembly, so that the outlet end of the injection assembly is deviated from the fixed template and points to the outer area of the fixed template, and the screw rod is not blocked by the fixed template when being pulled out of the plasticizing assembly. Therefore, when the screw rod is replaced, the process of disassembling and assembling the injection assembly is not needed, and the screw rod has enough operation space and is simple and convenient to operate. The front rotating shaft and the rear rotating shaft are generally fixed on the injection assembly and then are inserted into the rotating bearing to realize rotating connection, and the arrangement is more complex in structure and difficult to operate, and based on the arrangement, the further improvement is that the front rotating shaft and the rear rotating shaft are half-tooth bolts and upwards penetrate through the rotating bearing; the light columns of the front rotating shaft and the rear rotating shaft are inserted into the rotating bearing in an interference fit mode, and the threaded columns are fixedly connected with the injection assembly. In order to improve the moving stability of the sliding plate and avoid falling off from the front support, the sliding plate is further improved in that the top of the front support is provided with a sliding plate which is horizontally arranged, U-shaped grooves are arranged on two opposite sides of the sliding block, the openings of the U-shaped grooves face horizontally and are oppositely arranged, and the U-shaped grooves are clamped with the side parts of the sliding plate. The position structure of the rolling bearing directly influences the movement stability of the sliding block, and based on the position structure, the further improvement is that a connecting shaft which is vertically arranged is led out downwards from the upper groove wall of the U-shaped groove, and the rolling bearing is arranged on the connecting shaft and is in rolling connection with the side surface of the sliding plate. The sliding block slides on the upper end face of the sliding plate, and the
