The existing plasticizing unit is shown in figures 1 and 2 and mainly comprises a charging barrel 1 and a screw rod 2 which are mutually nested, a pressing block 3 is arranged above the charging barrel 1, the pressing block 3 is fixed with a charging barrel seat 7 through a screw I4, and the charging barrel 1 is limited between the pressing block 3 and the charging barrel seat 7; one end of the charging barrel 1 is provided with a charging barrel nut 5, the charging barrel nut 5 is limited at a charging barrel seat 7, and the charging barrel nut 5 is provided with a set screw 6.
Each part of current plastify unit is heavy, and traditional mounting means is clumsy, wastes time and energy, specifically is: firstly, a charging barrel 1 is adjusted into a charging barrel seat 7, a charging barrel nut 5 is screwed, a set screw 6 is screwed, a pressing block 3 is installed above the charging barrel 1, and the pressing block 3 is fixed on the charging barrel seat 7 through a first screw 4. In the alternation of pressure build-up and pressure release during injection, the charging barrel 1 is continuously stretched and rebounded, so that a large torsion force is needed when the charging barrel nut 5 is screwed in order to ensure that the charging barrel nut 5 is tightly attached to the charging barrel seat 7 and prevent the charging barrel 1 from moving back and forth on the charging barrel seat 7. The screwing tool wrench 8 of the cartridge nut 5 is very heavy, and the large tool can be sleeved on the cartridge nut 5 by two operators, and usually, the torsion F reaches hundreds of kilograms to several tons, the manpower can not be provided, and the assembly can be carried out by using the lifting force of a travelling crane. Also, it is time consuming and laborious to disassemble the plasticizing unit. Moreover, it is clear that both the mounting and the dismounting require a relatively large operating space.
The assembly mode of current plastify unit, no matter installation in earlier stage or subsequent maintenance dismantlement need three people to cooperate mutually at least, but also need use the driving cooperation installation, wastes time and energy, and the calibration is inconvenient, and torsion inaccuracy, the assembly precision is poor, certain potential safety hazard in addition.
Disclosure of Invention
The utility model discloses the technical problem that will solve is: how to reduce the installation of plastify unit and dismantle the degree of difficulty, simplify the installation, improve the assembly precision, reduce assemble duration and human cost, improve work efficiency to stop using the driving in the stage that compresses tightly, eliminate the potential safety hazard.
In order to solve the problems, the utility model provides an easy-to-install plasticizing unit, which comprises a material cylinder and a screw rod which are mutually nested, wherein the material cylinder is fixed on a material cylinder seat through a pressing block; the two sides of the part of the charging barrel seat, which is arranged between the pressing block and the charging barrel nut in the axial direction, are provided with gaps, and the part is fixed with a set screw, two ends of which respectively abut against the pressing block and the charging barrel nut.
Preferably, the number of the set screws is two, and the set screws are symmetrically arranged on two sides of the central shaft of the charging barrel.
Preferably, the tops of the charging barrel and the charging barrel seat are provided with depressions matched with the bottom surface of the pressing block.
Preferably, a loose nut is arranged on the set screw.
Compared with the prior art, the beneficial effects of the utility model reside in that:
1. the effect of the charging barrel nut is increased by adopting a smaller set screw, and the charging barrel nut is installed by using a torque wrench, so that the charging barrel nut is time-saving and labor-saving to assemble and disassemble, is convenient to measure, and improves the assembly precision;
2. the set screw need not huge torsion and can make feed cylinder nut compress tightly, need not to use the driving, eliminates the potential safety hazard, and single can accomplish swiftly to install and remove, has practiced thrift the human cost and has improved work efficiency.

Detailed Description
In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
Examples
As shown in fig. 3-5, an easily assembled plasticizing unit includes a material cylinder 1 and a screw rod 2 which are nested with each other, the material cylinder 1 is fixed on a material cylinder seat 7 through a pressing block 3, the pressing block 3 is connected and fixed with the material cylinder seat 7 through a first screw 4, a material cylinder nut 5 is arranged on one side of the material cylinder seat 7, the material cylinder nut 5 is limited at the position of the material cylinder seat 7, and the pressing block 3 is connected and fixed with the material cylinder 1 through a second screw 10; the charging barrel base 7 is provided with a gap on both sides of a part between the pressing block 3 and the charging barrel nut 5 in the axial direction, and the part is fixed with a set screw 6 of which both ends respectively abut against the pressing block 3 and the charging barrel nut 5. The number of the set screws 6 is two, and the set screws are symmetrically arranged on two sides of the central shaft of the charging barrel 1. The set screw 6 provides sufficient torque F' to fully tighten the cartridge nut 5 against the cartridge holder 7. The top surfaces of the charging barrel 1 and the charging barrel seat 7 are milled with a recess which is matched with the pressing block 3, so that most or all of the pressing block 3 is sunk into the recess.
The assembling process comprises the following steps: fixing a pressing block 3 on a charging barrel 1 by using a screw II 10, putting the charging barrel 1, a screw rod 2 and the pressing block 3 which are connected and fixed together into a charging barrel seat 7, manually screwing a charging barrel nut 5, propping the pressing block 3 by using a set screw 6 with a certain torque F', firmly pressing the charging barrel nut 5 on the charging barrel seat 7, screwing a loosening nut 9, and finally connecting and fixing the pressing block 3 with the charging barrel seat 7 by using a screw I4. The set screw 6 is much smaller than the charging barrel nut 5, the required torque is much smaller, and only a torque wrench needs to be screwed manually, so that time and labor are saved.
