Description

Technical Field

[0001] This application relates to the technical field of blow molding machines, and in particular to a blow molding apparatus for automotive interiors. Background Technology

[0002] A blow molding machine is a plastic processing machine that sprays liquid plastic and then uses a mold to extrude it into a finished product of a certain shape. The plastic raw material enters the heating mechanism from the feed hopper, where it melts and is blown out through the blow nozzle, then extruded through the mold and cooled to form the final product.

[0003] Currently, during blow molding, some plastic material remains on the outside of the mold. After cooling, the left and right molds open, and the finished product falls from the mold. Users need to cut off the plastic residue and then polish it. The cutting process requires a dedicated person to collect the residue and cut it manually, which is labor-intensive and resource-intensive, and slows down production efficiency. Utility Model Content

[0004] In order to improve the production efficiency of blow-molded products, this application provides a blow molding equipment for automotive interiors.

[0005] The blow molding equipment for automotive interiors provided in this application adopts the following technical solution:

[0006] A blow molding machine for automotive interior parts includes a machine body, a feeding bin connected to the machine body, a heating mechanism connected to the feeding bin, a mold connected to the machine body, a drive mechanism located on both sides of the mold, and a cutting mechanism connected to the drive mechanism. The mold is located directly below the heating mechanism, and the drive mechanism drives the cutting mechanism to reciprocate between the mold and the heating mechanism.

[0007] By adopting the above technical solution, when users clean up the end waste of blow-molded products, the drive mechanism drives the cutting mechanism to reciprocate between the mold and the heating mechanism to remove the end waste of the blow-molded products. This eliminates the need for users to collect the blow-molded products separately for centralized processing, reduces the user's work steps, improves production efficiency, and facilitates the user's cutting of blow-molded product waste.

[0008] Optionally, the driving mechanism includes a base and a power component connected to the base. The cutting mechanism is mounted between the mold and the heating mechanism via the power component, and the power component drives the cutting mechanism to move along the base.

[0009] By adopting the above technical solution, the base provides an installation position for the power component and the cutting mechanism, and the power component provides power for the movement of the cutting mechanism.

[0010] Optionally, the power assembly includes a power motor fixedly connected to the base, a power screw rotatably connected to the base, a slider slidably connected to the base, and a guide rod fixedly connected to the base. The output end of the power motor is coaxially fixedly connected to one end of the power screw. The axial direction of the guide rod is parallel to the axial direction of the power screw. The power screw passes through and is threadedly connected to the slider. The guide rod passes through and is slidably connected to the slider. The cutting mechanism is connected to the slider.

[0011] By adopting the above technical solution, after the power motor starts, it drives the power screw to rotate, so that the slider drives the cutting mechanism to move under the constraint of the base. The guide rod strengthens the constraint on the slider, and both ends of the slider are subjected to force, making the movement of the slider more stable and realizing the cutting of waste material at the end of blow-molded products.

[0012] Optionally, the cutting mechanism includes a reciprocating assembly connected to the slider and a saw connected to the reciprocating assembly. The saw is slidably connected to the slider along the length direction of the slider, and the sliding direction of the saw is perpendicular to the axial direction of the power screw. The saw is mounted between the mold and the bottom end of the heating mechanism.

[0013] By adopting the above technical solution, the reciprocating component drives the saw to reciprocate along the length of the saw, thereby achieving the purpose of cutting off the waste material at the end of the blow-molded product.

[0014] Optionally, the reciprocating assembly includes a reciprocating motor fixedly connected to the slider, a drive rod fixedly connected to the output end of the reciprocating motor, and a connecting rod rotatably connected to the end of the drive rod. The two ends of the drive rod are respectively connected to the output end of the reciprocating motor and one end of the connecting rod, and the other end of the connecting rod is rotatably connected to the saw.

[0015] By adopting the above technical solution, after starting the reciprocating motor, it drives the drive rod to rotate, and through the linkage structure of the drive rod and the connecting rod, it drives the saw to reciprocate along the length of the slider.

[0016] Optionally, the base has two sliding grooves, the two ends of the power screw are rotatably connected to the inner walls of the two ends of the sliding groove, the two ends of the guide rod are fixedly connected to the inner walls of the two ends of the sliding groove, the length direction of the sliding groove is parallel to the length direction of the guide rod, and the slider is slidably connected to the inner wall of the sliding groove.

[0017] By adopting the above technical solution, the sliding groove limits and protects the power screw and guide rod, and limits the slider, making the movement of the slider more stable.

[0018] Optionally, a reciprocating groove is provided at the top of the slider, and the saw is slidably connected to the inner wall of the reciprocating groove.

[0019] By adopting the above technical solution, a limit is provided for the saw, enabling the saw to reciprocate along a straight line, thereby cutting the end waste of blow-molded products.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] The drive mechanism and cutting mechanism in this application work together to cut off the waste material residue of blow-molded products above the mold through the reciprocating motion of the saw, thereby improving the user's production efficiency. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail.

[0026] Currently, in order to improve the production efficiency of blow-molded products, this application proposes a blow molding equipment for automotive interiors.

[0027] This application discloses a blow molding apparatus for automotive interior components. (Refer to...) Figure 1 A blow molding device for automotive interiors includes a machine body 1, a feeding bin 2 connected to the machine body 1, a heating mechanism 3 connected to the feeding bin 2, a mold 4 connected to the machine body 1, a drive mechanism 5 located on both sides of the mold 4, and a cutting mechanism 6 connected to the drive mechanism 5. The mold 4 is located directly below the heating mechanism 3, and the drive mechanism 5 drives the cutting mechanism 6 to reciprocate between the mold 4 and the heating mechanism 3.

[0028] When users clean up the end waste of blow-molded products, the drive mechanism 5 drives the cutting mechanism 6 to reciprocate between the mold 4 and the heating mechanism 3 to remove the end waste of the blow-molded products. This eliminates the need for users to collect the blow-molded products separately for centralized processing, reduces user work steps, improves production efficiency, and makes it easier for users to cut the waste of blow-molded products.

[0029] Reference Figure 1 and Figure 2 The drive mechanism 5 includes a base 51 fixedly connected to the machine body 1 and a power assembly 52 connected to the base 51. The base 51 provides an installation position for the power assembly 52 and the cutting mechanism 6. The power assembly 52 provides power for the movement of the cutting mechanism 6. The power assembly 52 includes a power motor 521 fixedly connected to the base 51, a power screw 522 rotatably connected to the base 51, a slider 523 slidably connected to the base 51, and a guide rod 524 fixedly connected to the base 51. The output end of the power motor 521 is coaxially fixedly connected to the power screw 524. One end of rod 522, the axis of guide rod 524 is parallel to the axis of power screw 522, and two sliding grooves 511 are opened on both sides of the top of base 51. The length of sliding groove 511 is parallel to the length of guide rod 524. Slider 523 is slidably connected to the inner wall of sliding groove 511. The two ends of power screw 522 are rotatably connected to the inner walls of the two ends of sliding groove 511. The two ends of guide rod 524 are fixedly connected to the inner walls of the two ends of sliding groove 511. Sliding groove 511 limits and protects power screw 522 and guide rod 524.

[0030] Furthermore, the power screw 522 passes through and is threadedly connected to the slider 523, the guide rod 524 passes through and is slidably connected to the slider 523, and the sliding groove 511 limits the slider 523, making the movement of the slider 523 more stable. At the same time, the cutting mechanism 6 is connected to the slider 523, realizing the purpose of the cutting mechanism 6 being mounted between the mold 4 and the heating mechanism 3 through the power component 52.

[0031] After the power motor 521 starts, it drives the power screw 522 to rotate, so that the slider 523 drives the cutting mechanism 6 to move under the constraint of the base 51. The guide rod 524 strengthens the constraint on the slider 523. Both ends of the slider 523 are subjected to force, making the movement of the slider 523 more stable. The power component 52 drives the cutting mechanism 6 to move along the base 51 to realize the cutting of the waste material at the end of the blow-molded product.

[0032] Reference Figure 1 and Figure 2The cutting mechanism 6 includes a reciprocating assembly 61 connected to the slider 523 and a saw 62 connected to the reciprocating assembly 61. The sliding direction of the saw 62 is perpendicular to the axial direction of the power screw 522. The reciprocating assembly 61 includes a reciprocating motor 611 fixedly connected to the slider 523, a drive rod 612 fixedly connected to the output end of the reciprocating motor 611, and a connecting rod 613 rotatably connected to the end of the drive rod 612. The two ends of the drive rod 612 are respectively connected to the output end of the reciprocating motor 611 and one end of the connecting rod 613. The other end of the connecting rod 613 is rotatably connected to the saw 62. After the reciprocating motor 611 is started, it drives the drive rod 612 to rotate. Through the linkage structure of the drive rod 612 and the connecting rod 613, the saw 62 is driven to reciprocate along the length direction of the slider 523. A reciprocating groove 5231 is provided on the top of the slider 523. The saw 62 is slidably connected to the inner wall of the reciprocating groove 5231, so that the saw 62 can slide along the length direction of the slider 523 and be connected to the slider 523. This provides a limit for the saw 62 and enables the saw 62 to be mounted between the bottom of the mold 4 and the heating mechanism 3, so that the saw 62 can reciprocate along a straight line to cut the end waste of the blow-molded product.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
