Description

Technical Field

[0001] This utility model relates to the field of two-color injection molding technology, and in particular to a backpack two-color injection structure. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are often called "pig injection machines" in many factories, and injection-molded products are called "pig injection parts." They are the main molding equipment used to create various shapes of plastic products from thermoplastic or thermosetting materials using plastic molds. Injection molding machines can be classified into vertical, horizontal, and vertical-horizontal combined types according to the arrangement of the injection unit and mold clamping unit.

[0003] Two-shot injection molding, as a unique injection molding method, can produce special-purpose products that require different colors or material combinations, meeting specific needs and creating a wider variety of appearances, so that molded products are no longer limited to a single look. Traditional two-color injection molding machines are mostly set up as parallel two-injection units on the same horizontal plane. Because they use two injection units, the overall footprint is large. If the two injection units are set up as a vertically stacked structure, the space occupied between the two injection units will result in a large center distance between the two material tubes, leading to a large center distance between the two nozzles at the injection ends of the two material tubes, making it difficult to meet the user's processing requirements.

[0004] Therefore, a new technology needs to be developed to solve the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a backpack-type dual-color injection structure, which can effectively reduce the overall footprint and reduce the center distance between the two nozzles at the injection ends of the two material tubes, thereby meeting the processing needs of users.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A backpack-type dual-color injection molding structure includes a first injection mechanism and a second injection mechanism; the second injection mechanism is mounted on a support frame, the support frame is arranged horizontally above the first injection mechanism, the upper end of the support frame is an inclined mounting surface, the second injection mechanism is mounted on the mounting surface, and the included angle between the second injection mechanism and the first injection mechanism is an acute angle;

[0008] The first injection mechanism includes a first feed tube and a first nozzle connected to the injection end of the first feed tube. The second injection mechanism includes a second feed tube and a second nozzle connected to the injection end of the second feed tube. The included angle between the second feed tube and the first feed tube is the same as the included angle between the second injection mechanism and the first injection mechanism. The second nozzle and the first nozzle are parallel to each other.

[0009] As a preferred embodiment, the support frame can be arranged transversely above the first material tube, moving back and forth along its length.

[0010] As a preferred embodiment, the support frame includes a support platform and a movable frame with a U-shaped structure. The movable frame surrounds the first material pipe. The support platform extends obliquely and is installed on the upper end of the movable frame. The oblique mounting surface is formed on the upper end of the support platform. The movable frame is connected to a drive mechanism, which drives the movable frame to move back and forth along the length direction of the first material pipe.

[0011] As a preferred embodiment, the movable frame includes a first vertical plate, a second vertical plate, a first horizontal plate, and a second horizontal plate. The first horizontal plate and the second horizontal plate are respectively arranged on the upper and lower sides of the first material tube. The first vertical plate and the second vertical plate are symmetrically arranged on both sides of the first material tube. The first horizontal plate, the first vertical plate, the second horizontal plate, and the second vertical plate are sequentially connected end to end to form a movable frame with a U-shaped structure. The support platform is installed on the upper end of the first horizontal plate.

[0012] As a preferred embodiment, the lower end of the second transverse plate is connected to a slider, the slider being adapted to a slide rail, the slide rail extending along the length direction of the first material tube.

[0013] As a preferred embodiment, the driving mechanism includes a first driving rod and a first driving unit connected to the first driving rod, and the movable frame is connected to the first driving rod.

[0014] As a preferred embodiment, the first injection mechanism is mounted on the movable end of a movable platform. The movable platform includes a base, a guide post mounted on the base, a mounting seat connected to the guide post, a second drive unit mounted on the base, a second drive rod connected to the second drive unit, and a connecting seat mounted on the bottom of the mounting seat. The second drive rod is connected to the connecting seat, and the first injection mechanism is mounted on the mounting seat.

[0015] Compared with the prior art, this utility model has significant advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly involves installing the second injection mechanism on a support frame, with the support frame arranged horizontally above the first injection mechanism. This allows the second and first injection mechanisms to be stacked vertically, effectively reducing the overall footprint. By making the upper end of the support frame an inclined mounting surface, the second injection mechanism is installed on the mounting surface, making the included angle between the second and first injection mechanisms an acute angle. The included angle between the second and first material tubes is also consistent with the included angle between the second and first injection mechanisms. The second nozzle is parallel to the first nozzle, thus bringing the injection ends of the second and first injection mechanisms as close as possible. This reduces the center distance between the two nozzles at the injection ends of the two material tubes, meeting the user's processing needs and reducing the height difference between the two injections to a certain extent, thereby reducing the gravitational potential energy difference between them.

[0036] Please refer to Figures 1 to 4 As shown, it illustrates the specific structure of the backpack-type dual-color injection molding structure provided in an embodiment of the present invention.

[0037] The backpack-type dual-color injection structure includes a first injection mechanism 10 and a second injection mechanism 20. The second injection mechanism 20 is mounted on a support frame 30, which is arranged horizontally above the first injection mechanism 10. In this way, the second injection mechanism 20 and the first injection mechanism 10 can be stacked vertically, which can effectively reduce the overall footprint.

[0038] The upper end of the support frame 30 is an inclined mounting surface that extends obliquely upward from left to right. The second injection mechanism 20 is mounted on the mounting surface. The included angle between the second injection mechanism 20 and the first injection mechanism 10 is an acute angle, which can be 35° but is not limited to this angle. The first injection mechanism 10 includes a first material tube 11 and a first nozzle 12 connected to the injection end of the first material tube 11. The second injection mechanism 20 includes a second material tube 21 and a second nozzle 22 connected to the injection end of the second material tube 21. The included angle between the second material tube 21 and the first material tube 11 is the same as the included angle between the second injection mechanism 20 and the first injection mechanism 10. The second nozzle 22 is parallel to the first nozzle 12. In this way, the injection ends of the second injection mechanism 20 and the first injection mechanism 10 can be brought as close as possible, thereby reducing the center distance between the two nozzles at the injection ends of the two material tubes, meeting the user's processing needs, and reducing the height difference between the two injections to a certain extent, thereby reducing the gravitational potential energy difference between the two.

[0039] The support frame 30 is arranged horizontally above the first material pipe 11, capable of moving back and forth along its length. The support frame 30 includes a support platform 31 and a movable frame 32 with a U-shaped structure. The movable frame 32 surrounds the first material pipe 11. The support platform 31 extends obliquely and is installed on the upper end of the movable frame 32. The oblique mounting surface is formed on the upper end of the support platform 31. The movable frame 32 is connected to a driving mechanism, which drives the movable frame 32 to move back and forth along the length of the first material pipe 11.

[0040] The drive mechanism includes a first drive rod and a first drive unit connected to the first drive rod. The movable frame 32 is connected to the first drive rod. The first drive unit is preferably a hydraulic cylinder. Of course, the first drive unit can also be designed as other drives, such as a motor, as long as it is set according to the actual production needs.

[0041] The movable frame 32 includes a first vertical plate 321, a second vertical plate 322, a first horizontal plate 323, and a second horizontal plate 324. The first horizontal plate 323 and the second horizontal plate 324 are respectively arranged on the upper and lower sides of the first material tube 11. The first vertical plate 321 and the second vertical plate 322 are symmetrically arranged on both sides of the first material tube 11. The first horizontal plate 323, the first vertical plate 321, the second horizontal plate 324, and the second vertical plate 322 are connected end to end to form a single movable frame 32 with a U-shaped structure. The support platform 31 can be detachably installed on the upper end of the first horizontal plate 323 by means of screw fastening connection.

[0042] The lower end of the second transverse plate 324 is connected to a slider 40, the slider 40 is adapted to a slide rail 50, the slide rail 50 extends along the length of the first material tube 11, and the slide rail 50 is installed on the machine base of the injection molding machine.

[0043] The first injection mechanism 10 is mounted on the movable end of a movable platform 60. The movable platform 60 includes a base 61, a guide post 62 mounted on the base 61, a mounting seat 63 connected to the guide post 62, a second drive unit 64 mounted on the base 61, a second drive rod 65 connected to the second drive unit 64, and a connecting seat 66 mounted on the bottom of the mounting seat 63. The second drive rod 65 is connected to the connecting seat 66. The first injection mechanism 10 is mounted on the mounting seat 63. Here, the second drive unit 64 is preferably a hydraulic cylinder. Of course, the second drive unit 64 can also be designed as other drives, such as a motor, as long as it is set according to the actual production needs.

[0044] A mold base 70 is also provided on the left side of the first injection mechanism 10 and the second injection mechanism 20. The mold base 70 has a first through hole 71 and a second through hole 72 arranged at a vertical distance. The first nozzle 12 and the second nozzle 22 are respectively inserted into the second through hole 72 and the first through hole 71. The right end of the mold base 70 is recessed to the left and has a receiving cavity 73. The left ends of the first through hole 71 and the second through hole 72 extend to the left end face of the mold base 70, and the right ends of the first through hole 71 and the second through hole 72 extend to the receiving cavity 73. The left ends of the first material tube 11 and the second material tube 21 both extend into the receiving cavity 73, and the left end of the second material tube 21 is located above the left end of the first material tube 11.

[0045] In summary, the key design feature of this utility model lies in mounting the second injection mechanism on a support frame, with the support frame positioned horizontally above the first injection mechanism. This allows the second and first injection mechanisms to be stacked vertically, effectively reducing the overall footprint. By making the upper end of the support frame an inclined mounting surface, the second injection mechanism is mounted on this surface, creating an acute angle between the second and first injection mechanisms. The angle between the second and first feed tubes is also aligned with the angle between the second and first injection mechanisms. The second nozzle is parallel to the first nozzle, allowing the injection ends of the second and first injection mechanisms to be as close as possible. This reduces the center distance between the two nozzles at the injection ends of the two feed tubes, meeting the user's processing requirements and reducing the height difference between the two injections to a certain extent, thereby reducing the gravitational potential energy difference between them.

[0046] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
