Description

Technical Field

[0001] This invention relates to the field of injection molding technology, and in particular to an insert flipping device for injection molding production. Background Technology

[0002] Injection molding production involves placing various inserts according to the design requirements of the parts. Due to the differences in parts, the types, placement directions, and materials of inserts vary. To ensure that inserts are accurately and reliably placed into the mold and to prevent displacement during production, auxiliary positioning components for inserts are designed to facilitate gripping by robotic arms. Because of the differences in position and direction, the direction and angle of inserts need to be flexibly adjusted during installation and placement. Therefore, a robotic arm that can flexibly grip and adjust the direction in a timely manner is required, which leads to the use of an insert flipping device for injection molding production. Traditional insert flipping equipment used in injection molding production is cumbersome to operate during flipping and is prone to misalignment, which can lead to errors in the position of the insert auxiliary seat when closing, making it impossible to install the insert and affecting work efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide an insert flipping device for injection molding production, which solves the problem of poor flipping accuracy in existing insert flipping devices for injection molding production.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an insert flipping device for injection molding production, including a base; A flip bracket is fixedly installed on both sides of the base, a support plate is provided at the middle position above the base, and a flip structure is provided on both sides of the support plate above the base. The flipping structure includes flipping base plates disposed on both sides of the support plate above the base. A flipping cylinder is disposed on one side below the flipping base plate. One end of the flipping cylinder is hinged to a lower hinge seat, and the other end of the flipping cylinder is hinged to an upper hinge seat. Rotating seats are fixedly installed on both sides of the flipping base plate. A rotating shaft is fixedly installed on one side of the bottom of the rotating seat. A limit plate is fixedly installed on the outer side of the rotating seat at the top of the flipping base plate. Clamping structures are fixedly installed on both sides of the top of the flip base plate.

[0005] Preferably, a first snap-fit ​​block is fixed on the outer wall of both sides of the base, a fixing bolt is evenly arranged at both ends inside the flip bracket, a snap-fit ​​groove is provided on one side of the fixing bolt inside the flip bracket, and a second snap-fit ​​block is evenly fixed on the outer wall of both sides of the support plate.

[0006] Preferably, the flip bracket is fixedly connected to both sides of the base and the support plate by fixing bolts, and the first snap-fit ​​block and the second snap-fit ​​block are snapped into the flip bracket by snap-fit ​​grooves.

[0007] Preferably, the bottom end of the lower hinge seat is fixedly connected to one side of the top end of the base, and the top end of the upper hinge seat is fixedly connected to one side of the bottom end of the flip base plate.

[0008] Preferably, the outer wall of the rotating seat and the outer wall of the flipping base are located on the same plane, and one end of the rotating shaft extends into the interior of the flipping bracket and is rotatably connected to the flipping bracket.

[0009] Preferably, a first chamfer is provided at the bottom of one end of the limiting plate, and a second chamfer is provided at the bottom of the other end of the limiting plate. When the flipping base plate is in a horizontal state, one side of the first chamfer abuts against the top of the flipping bracket. When the flipping base plate is in a vertical state, one side of the second chamfer abuts against one side of the flipping bracket.

[0010] Preferably, the clamping structure includes cylinder seats fixedly installed on both sides of the top of the flipping base plate. Each cylinder seat has a finger cylinder fixedly installed inside. Each flipping base plate near the support plate has a clamping seat fixedly installed on its top. Each finger cylinder has a hinge rod hinged to both sides at one end. Each clamping seat has a reserved groove on one side and a sliding groove on the other side. Each sliding groove has a slider on both sides. Each slider has one end extending to the outside of the clamping seat and fixedly installed with a special clamping finger. An insert auxiliary seat is provided between adjacent special clamping fingers. A positioning spring plunger passes through the interior of the flipping base plate below the insert auxiliary seat.

[0011] Preferably, one end of the hinge rod extends through the reserved groove into the interior of the slide groove, and the inner wall of the slider is hinged to one end of the hinge rod.

[0012] Preferably, the slider and the clamping seat form a sliding structure through a groove, and the special clamping finger is fixedly connected to the outer wall of the slider by bolts.

[0013] Preferably, the top end of the positioning spring plunger abuts against the bottom end of the insert auxiliary seat, and a limit ring is fixed on the outer wall of the positioning spring plunger.

[0014] The present invention provides an insert flipping device for injection molding production, the advantages of which are: By incorporating a flipping structure and activating the flipping cylinder, the cylinder drives the rotating shaft to rotate inside the flipping bracket via the flipping base plate. When the flipping base plate is in a horizontal state, one side of the first chamfer abuts against the top of the flipping bracket. When the flipping base plate is in a vertical state, one side of the second chamfer abuts against one side of the flipping bracket. Under the limiting action of the limiting plate, the flipping base plate switches between horizontal and vertical states, preventing deviation during flipping and enhancing flipping accuracy. This improves the working efficiency of the insert flipping equipment for injection molding production. By incorporating a clamping structure, activating the finger cylinder causes the sliders on both sides of the slide groove to move in opposite directions via a hinged rod. This causes the sliders to move the dedicated clamping fingers, which then clamp and fix the insert auxiliary seat. The height of the insert auxiliary seat can be adjusted via a positioning spring plunger, enabling the device to easily clamp and fix the insert, saving time and labor, and thus improving the convenience of using the insert flipping equipment for injection molding production.

The bottom end of the lower hinge seat 32 is fixedly connected to one side of the top of the base 1. The top end of the upper hinge seat 34 is fixedly connected to one side of the bottom of the rotating base plate 31. The outer side wall of the rotating seat 35 and the outer side wall of the rotating base plate 31 are located on the same plane. One end of the rotating shaft 36 extends into the interior of the rotating bracket 2 and is rotatably connected to the rotating bracket 2. A first chamfer 371 is provided at the bottom of one end of the limiting plate 37, and a second chamfer 372 is provided at the bottom of the other end of the limiting plate 37. When the rotating base plate 31 is in a horizontal state, one side of the first chamfer 371 abuts against the top of the rotating bracket 2. When the rotating base plate 31 is in a vertical state, one side of the second chamfer 372 abuts against one side of the rotating bracket 2.

[0020] When the flipping cylinder 33 is activated, it drives the rotating shaft 36 to rotate inside the flipping bracket 2 via the flipping base plate 31. When the flipping base plate 31 is in a horizontal state, one side of the first chamfer 371 abuts against the top of the flipping bracket 2. When the flipping base plate 31 is in a vertical state, one side of the second chamfer 372 abuts against one side of the flipping bracket 2. Under the limiting action of the limiting plate 37, the flipping base plate 31 switches between horizontal and vertical states.
