Description

Technical Field

[0001] The present invention relates to the technical field of plastic injection molding, and in particular to an extrusion device for processing a battery box and a mold assembly method thereof. Background Art

[0002] In the production of battery boxes, the injection molding extruder conveys molten plastic into the injection mold, and then the plastic is shaped. Different types of molds can be replaced to produce battery boxes of different shapes. When the injection mold is replaced and installed, there is a problem that the discharge port of the plastic extruder barrel and the feed port of the mold do not align. Then, the plastic will leak at the joint during delivery, affecting the injection molding of the plastic. There are many reasons for the misalignment, such as the unreasonable design of the mold itself, the incorrect position of the feed port on the mold itself, and the offset feed port is not directly opposite the discharge port of the extruder barrel; when the mold is assembled at one end of the extruder barrel, the mold accidentally collides with the external mold bracket, causing slight deformation of the mold bracket. In this way, the mold is installed on the offset mold bracket, and the feed port on the mold has deviated from the specified position; the external bracket that fixes the mold itself has a design problem, resulting in any model of mold installed having the problem of incorrect mold feed port position. Redesigning and modifying the mold or mold frame is not enough to meet production needs. Based on the mold assembly process, the mold feed port and the extruder barrel discharge port automatically adapt to the docking requirements, so that the port docking has a certain fault tolerance rate.

The fixed shaft 51 is also movably sleeved in a through hole opened in the middle of the Y-shaped plate 52, and the outer ring gear 50 is engaged with the second rack 44 for transmission connection.

[0043] A method for assembling a mold of an extrusion device for processing a battery box, comprising the following steps: Step 1: A worker controls the machine to select and extract a target mold 3 from different types of molds 3, controls the target mold 3 to be transported to a position on one side of the mold mounting seat 4, and then pushes the mold 3 horizontally into the mold mounting seat 4; Step 2: After the mold 3 is translated into position, a row of feed pipes 10 on the mold 3 are automatically adapted and plugged into a portion of the adaptor assemblies 8 in a row of adaptor assemblies 8, and the plastic conveying channels in the converters 6 corresponding to the adaptor assemblies 8 are automatically opened; Step 3: The plastic delivery channels in the converters 6 corresponding to the remaining adapter integrators 8 in a row of adapter integrators 8 are automatically closed, and the flushing water supply channel is opened at the same time; Step 4: Tighten the fastening screws on the mold mounting base 4 to tighten the contact connection between the mold 3 and the mold mounting base 4, and the mold 3 and the mold mounting base 4 are closed.

[0044] The die 3 is moved closer to the extruder barrel 1, and the feed pipe 10 on the die 3 is inserted into the follower barrel 33. Before the insertion, the positioning of the coarse ring plate 35 is first released. Specifically, the pressure plate 30 presses the second rack 44, which then causes the second rack 44 to move in parallel. Figure 13, which is the state where the second rack 44 has translated to the right to the end. Before the translation, the protrusion of the second rack 44 is engaged with the arc groove at the left end of the leveling column 45, and the engagement corresponds to the positioning of the thick ring plate 35. When the second rack 44 translates, the leveling column 45 is supported and moves. Figure 13 The horizontal control column 45 in the middle descends and presses the swing control column 48. The swing control column 48 swings to drive the worm 40 to rotate. Then the main shaft 41 drives the two sub-shafts 38. The rotation of the sub-shafts 38 causes the push-pull plate 37 to move, and then the two push-pull plates 37 and the limit ring plate 31 move synchronously. Figure 10 The limiting ring plate 31 in the middle drives the sealing ring gasket 32 to move to the right. The sealing ring gasket 32 no longer presses the edge of the coarse ring plate 35. The coarse ring plate 35 can move in the circular hole of the disc box 29. Then the feed pipe 10 is gradually inserted into the follower cylinder 33. If the feed pipe 10 is not facing the middle of the follower cylinder 33, the follower cylinder 33 will be supported and offset during the insertion of the feed pipe 10. The feed pipe 10 is finally fully connected with the discharge cylinder 34. At this time, the second rack 44 has been completely translated to the end, that is, Figure 13 In the state shown in the figure, the protrusion of the second rack 44 is engaged with the arc groove at the right end of the horizontal control column 45, and the J-shaped spring piece 43 rebounds to make the swing control column 48 reset and swing, and then push the horizontal control column 45 back. After the horizontal control column 45 rises, it is engaged with the second rack 44. The reset swing of the swing control column 48 brings about subsequent transmission, and finally the limiting ring plate 31 re-covers the annular hole between the coarse ring plate 35 and the disc box 29, and the sealing ring gasket 32 presses the coarse ring plate 35 to reposition the coarse ring plate 35, and then the plastic can be transported in the disc box 29.

[0045] The process of inserting the feed pipe 10 into the follower cylinder 33 is accompanied by the conversion of the channel in the converter 6. Specifically, the pressure plate 30 presses the second rack 44. The translation of the second rack 44 also drives the folding column frame 9, which in turn causes the first rack 16 to translate. Next, the shaft 11 is introduced to drive the adjustment rod 15. The rotation of the adjustment rod 15 causes the integrated cylinder 17 to move, and then the cone 18 moves axially and separates from the sealing cylinder 19. The melted plastic in the extruder barrel 1 is injected into the diverter cap 5, and then passes through the unobstructed diverter tube 20, and then is injected into the disc box 29 through the hard tube 7, and then is injected into the feed pipe 10 through the discharge tube 34, and then injected into the mold 3 for final shaping. The remaining adapter integrators 8 that are not connected to the feed pipe 10 are drained to the outside, that is, in the corresponding converter 6, the sealing cylinder 19 and the cone 18 are in contact and sealed, the branch pipe cavity 22 port is exposed, and the water inlet pipe 14 is externally connected to the water supply mechanism in the prior art. The water flow is transported to the C-type plate cavity 21 through the water inlet pipe 14, and then injected into the inner cavity of the diversion tube 20 through the branch pipe cavity 22, and then flows along the plastic fluid channel mentioned above, except that the water flow is directly discharged at the adapter integrator 8 because there is no feed pipe 10 connected to the drainage adapter integrator 8. The plastic retained in the previous channel plastic transportation is flushed out through continuous drainage.

[0046] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
