The utility model discloses, including following work step:
s1: the third power unit 18 drives the third moving plate 14 to move upward in the vertical direction, so as to drive the upper end of the positioning rod 16 to pass through the working table 1 and to be matched with and pass through the through hole of the positioning plate 11. The positioning rod 16 positions the lower mold 10 to ensure that the lower mold 10 is at a predetermined position.
S2: the first power component 6 drives the first moving plate 4 to move downwards and drives the guide pipe 9 to move downwards until the upper end of the positioning rod 16 is inserted into the guide pipe 9 in a matched mode, so that the upper die 8 is positioned;
s3: the second power part 7 drives the second moving plate 5 to move downwards so as to drive the upper die 8 to be buckled with the lower die 10; the guide pipe 9 has a good guiding function on the second moving plate 5;
the utility model discloses in, through mutually supporting of locating lever 16 and stand pipe 9, realize respectively to last mould 8 and the lower mould 10 between the location, guarantee to go up the sealed lock of mould 8 and lower mould 10, improve subsequent quality of building. The equipment is accurate in positioning, simple in structure and good in using effect.
In an alternative embodiment, the third power component 18 comprises a movable rod 19 and a power assembly for driving the movable rod 19 to ascend and descend;
the third moving plate 14 is provided with a through hole for the moving rod 19 to pass through; a plurality of springs 17 are arranged at the bottom of the third moving plate 14; the lower end of the spring 17 is connected with the base 2;
the moving rod 19 is provided with a limiting plate 15, and the limiting plate 15 is located above the third moving plate 14.
In an optional embodiment, the device further comprises an ejection mechanism;
the ejection mechanism comprises an ejector pin mounting plate 13 and a plurality of ejector pins 12; the plurality of thimbles 12 are uniformly distributed and vertically arranged on the thimble mounting plate 13; the thimble mounting plate 13 is arranged at the upper end of the movable rod 19; an ejector plate is arranged in the lower die 10, and a through hole for the ejector pin 12 to pass through is arranged at the bottom of the lower die 10.
In the work, the process that the movable rod 19 moves upwards is divided into two stages to realize two steps, namely a positioning step and an ejection step;
the specific process of the positioning step is as follows:
the power assembly is started and controls the moving rod 19 to move upwards; the moving rod 19 drives the limiting plate 15 to move upwards, and the limiting plate 15 stops pressing the third moving plate 14 downwards; the third moving plate 14 moves upward under the action of the spring 17;

the power assembly stops controlling the movement of the moving rod 19.
The moving rod 19 has a certain guiding function for the third moving plate 14, and prevents the third moving plate 14 from tilting due to unbalanced force.
The specific process of the ejection step is as follows:
after the injection molding process is finished, the injection molded part needs to be ejected, and at the moment, the upper mold 8 is removed;
the power assembly continues to move the moving rod 19 upwards to drive the thimble mounting plate 13 to move upwards, so that the thimble 12 is controlled to be inserted into the lower die 10 to extrude the ejector plate to move upwards; the ejector plate smoothly ejects the injection molding piece.
It should be noted that, after the spring 17 is restored to a certain length, an upward acting force is not generated on the third moving plate 14 (the gravity of the third moving plate 14 is equal to the supporting force of the spring 17), and a balance is achieved; at this time, the moving rod 19 moves upward without bringing the third moving plate 14, thereby ensuring the stability of the apparatus.
After the positioning step and the ejecting step are both finished, the power assembly moving rod 19 moves downwards to the initial position, at this time, the spring 17 is in a compressed state, the upper end of the positioning rod 16 is positioned below the workbench 1, and the upper end of the thimble 12 is positioned below the workbench 1.

The guide pipes 9 are distributed around the upper die 8, the number of the guide pipes 9 is not less than four, the premise that three points determine one plane is met, and the accuracy of equipment positioning is improved.
In an alternative embodiment, the lower end of the guide tube 9 is flared.
In an alternative embodiment, the upper end of the locating rod 16 is tapered with the tip upward.
It should be noted that the upper end of the positioning rod 16 is more easily inserted into the guide tube 9, so as to improve the positioning efficiency and accuracy.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
