[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 1. The present invention uses two vertical multi-color injection molding machine components to synchronously perform injection molding production work, and this method effectively improves production operation efficiency.

[0037] 2. The present invention sets a dislocation groove so that the dislocation groove can protrude during the rotation of the output end of the locking swing arm structure and come into extrusion contact with the injection molding platform, which is the main measure to achieve the upward adjustment of the injection molding platform and control the contact between the mold and the injection molding output end of the vertical multi-color injection molding machine assembly.

[0038] 3. The present invention drives the screw to rotate through a servo drive motor so that the adjustment frame and the slider can be linearly raised and lowered along the slide rail.

At the same time, the power source is one to reduce the situation of multiple power sources required in similar multiple operating modes, thereby reducing the preparation cost.

[0039] 4. The present invention realizes staggered contact of the two power input ends of the locking swing arm structure by rotating the engagement bolts in contact with the spiral groove and the linear groove, so that the engagement bolts are rotated and adjusted 180 degrees along the spiral groove, so as to cause the lifting drive shaft to produce rotational adjustment, so as to form staggered lifting drive for the two independent small mold carrying platforms. In this way, the continuous injection molding of small and medium-sized injection molded parts is effectively improved. In this staggered manner, the injection molding waste and residual materials are removed by mechanical injection molding and manual unloading operations at the same time during the operation. In this way, the amount of waste and residual materials recycled and reused each time is effectively controlled, and the waste and residual materials are recycled and put into the hopper in small quantities and multiple times, which reduces the waste and residual materials that are put into use too much at one time. The material and residual material cause insufficient solubility; and the inclined one-way protrusion sliding end is connected to one of the starting ends of the spiral groove, and the height difference between the one-way protrusion sliding end and the starting end of the spiral groove is used to form a barrier, so that the rotating engagement bolt maintains a stable one-way sliding state, thereby improving the stability of the 180-degree rotation operation; and the rotating engagement bolt is manually adjusted to engage with the force sleeve thread, and the linear engagement bolt is manually rotated and adjusted to make the end of the linear engagement bolt contact with the limiting straight groove. In this way, the lifting drive shaft is prevented from rotating, so that the lifting drive shaft only makes a lifting movement to contact one of the power input ends of the locking swing arm structure, so that the integrated large mold carrying platform installed for the production of large injection molded parts can perform conventional lifting and lowering adjustments.

[0040] 5. The present invention can tighten and adjust the telescopic arm through the bolt D, and cooperate with manual adjustment of the extension distance of the telescopic arm to form an equidistant state and a long and short state for the two output ends of the swing arm body. When the two output ends of the swing arm body are in an equidistant state, the rotating engagement bolt is in contact and engaged with the spiral groove and the linear groove, so that the input arm is lifted and squeezed under the staggered lifting state of the pushing structure, forming an operation of staggered lifting and lowering of two independent small mold carrying platforms, and cooperates with the swing rod to synchronously drive the linkage articulated seat to rotate and deflect, and the limit connecting shaft slides along the compensation groove to compress the spring D. When the linkage articulated seat continues to rotate and deflect, the swing limit shaft as a whole is also rotated and adjusted. The force direction is from the opposite side to the linkage articulated seat and the central axis of the swing limit shaft, and then the force direction is from the opposite side to the other side. At this time, the elastic force of the spring D causes the end of the swing limit shaft to slide to one end of the limit groove, and through The elastic force of spring D is used to apply elastic force to the linkage hinge seat, so that the swing arm body as a whole remains stable, and this method is adapted to the advantages of light weight of the required small and medium-sized molds; and when the two output ends of the swing arm body are in a state of one long and one short, the rotating engagement bolt is engaged with the threaded engagement state of the force-bearing sleeve, and the end of the swing limit shaft is controlled to slide along the limit groove by manually plugging and installing the pin part, and the output force arm is rotated and raised by pushing the structure to perform a linear jacking state, so as to perform an upward movement of the integrated large mold carrying platform. At the same time, based on the size of the mounted mold, the lifting distance of the independent small mold carrying platform is short, so that the swing limit shaft is rotated and adjusted as a whole, and the force direction is linked to the hinge seat and the central axis of the swing limit shaft from the opposite side position, so that the large mold can contact the injection nozzle of the vertical multi-color injection molding machine assembly, and at the same time, the two vertical multi-color injection molding machine assemblies are set to effectively improve the injection molding effect and accelerate the production preparation efficiency.

[0041] 6. The present invention maintains the stability of the extrusion and lifting operation when the output force arm, the telescopic arm and the two input arms are in contact with the injection molding platform and the pushing structure respectively through the arc structure arranged at the ends of the output force arm, the telescopic arm and the two input arms.

[0064] It is worth noting that the locking swing arm structure 8 includes a swing arm body 801, a linkage articulated seat 802 and a swing limit shaft 803; the swing arm body 801 is hinged in the operation adjustment cavity through a swing rod 8011; wherein the swing arm body 801 includes an output force arm 8012, an output connecting arm 8013, a telescopic arm 8014 and two input arms 8015; wherein the swing arm body 801 is an "X" structure; wherein the telescopic arm 8014 and the output connecting arm 8013 are a multi-stage telescopic structure; and the telescopic arm 8014 is fastened to the output connecting arm 8013 by a bolt D; the linkage articulated seat 802 is fixedly arranged at one end of the swing rod 8011 relatively close to the swing brake block 105; and the linkage articulated seat 802 is fixedly arranged at one end of the swing rod 8011 relatively close to the swing brake block 105; and A limit connecting shaft 8021 is provided on the receiving seat 802; the swing limit shaft 803 is movably arranged on the limit connecting shaft 8021, and a compensation groove 8032 which is slidably matched with the limit connecting shaft 8021 is provided on the surface of the swing limit shaft 803, wherein the limit connecting shaft 8021 is elastically connected to the swing limit shaft 803 through a spring D; wherein the end of the swing limit shaft 803 is an arc structure; and a hinged plug-in groove 8031 ​​is provided at the end of the swing limit shaft 803, and the swing limit shaft 803 is installed and connected to the operating platform 1 through the hinged plug-in groove 8031 ​​and the latch member 9, and the swing limit shaft 803 is hingedly connected to the operating platform 1 through the latch member 9 and the hinged plug-in groove 8031. The present invention can tighten and adjust the telescopic arm 8014 through the bolt D, and cooperate with manual adjustment of the extension distance of the telescopic arm 8014 as shown in FIG. Figure 4 and Fig. 9As shown, the two output ends of the swing arm body 801 are in an equidistant state and a long and short state. When the two output ends of the swing arm body 801 are in an equidistant state, the rotating engagement bolt 602 is in a contact and engaged state with the spiral groove 7011 and the linear groove 7012, so that the input arm 8015 is lifted and squeezed under the staggered lifting state of the pushing structure 7, so that the two independent small mold carrying platforms are staggered and lifted. The swing rod 8011 synchronously drives the linkage articulated seat 802 to rotate and deflect, and the limit connecting shaft 8021 slides along the compensation groove 8032 to compress the spring D. When the linkage articulated seat 802 continues to rotate and deflect, the swing limit shaft 803 is also as a whole. When rotation adjustment occurs, the force direction is from the opposite side to the linkage hinge seat 802, and then the force direction is from the opposite side to the other side after the central axis of the swing limit shaft 803. At this time, the elastic force of the spring D causes the end of the swing limit shaft 803 to slide to one end of the limit groove 106, and the elastic force of the spring D is used to apply elastic force to the linkage hinge seat 802, so that the swing arm body 801 remains stable as a whole, and this method is adapted to the advantages of light weight of the required small and medium-sized molds; and when the two output ends of the swing arm body 801 are in a state of one long and one short, the rotating engagement bolt 602 is in threaded engagement with the force sleeve 601, and the end of the swing limit shaft 803 is controlled to slide along the limit groove 106 by manually plugging and installing the latch member 9, as shown in the following example. Fig. 9 The pushing structure 7 shown is in a linear lifting state, causing the output force arm 8012 to rotate and rise, so as to lift the integrated large-scale mold carrying platform. At the same time, based on the size of the carried mold and the short lifting distance of the independent small-scale mold carrying platform, the swing limit shaft 803 is rotated and adjusted as a whole. The force direction is linked to the hinge seat 802 and the central axis of the swing limit shaft 803 from the opposite side position, so that the large mold can contact the injection nozzle of the vertical multi-color injection molding machine assembly 2. At the same time, the two vertical multi-color injection molding machine assemblies 2 are set to effectively improve the injection molding effect and accelerate the production and preparation efficiency.

[0065] It is worth mentioning that the ends of the output arm 8012, the telescopic arm 8014 and the two input arms 8015 are all arc-shaped structures. The present invention maintains the stability of the extrusion and lifting operation when the output arm 8012, the telescopic arm 8014 and the two input arms 8015 are in contact with the injection molding platform 3 and the pushing structure 7 respectively through the arc-shaped structures arranged at the ends of the output arm 8012, the telescopic arm 8014 and the two input arms 8015.
