Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to a rotating frame for injection molds. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. During the injection molding process, when the workpiece is separated from the mold, a suction cup is needed to separate the workpiece from the mold. A good suction cup holder can effectively meet the user's needs to separate the workpiece from the mold, speed up the mold release efficiency, and bring convenience to the user.

[0003] The suction cup structure in the original injection molding machine is fixed and can only meet the requirements of one production process. After the suction cup sucks out the injection plastic and places it on the worktable, the number or number of subsequent processes will be different. The fixed base cannot be used for multiple processes. Therefore, we propose a rotating frame for injection molds. Utility Model Content

[0004] The purpose of this invention is to provide a rotating frame for injection molds to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotating frame for injection molds, comprising a support, a fixed plate, and a mounting frame. A plurality of suction cups are laid on one side surface of the support, and nuts are threadedly connected to the connection between the suction cups and the support. A fixed plate is welded to the middle of the support and is positioned at the center of gravity of the support. A fixed rod is welded to the lower surface of the fixed plate, and inclined telescopic rods are movably connected to both sides of the fixed rod. A movable head is welded to the bottom of the hydraulic telescopic rod, and a clamping arm is movably connected to the lower end of the movable head, with the fixed plate embedded in the lower end of the clamping arm.

[0006] Preferably, the bracket has a waist-tightening hole on its inner side, and the suction cup slides along the waist-tightening hole. The suction cup is fixed to the bracket by a nut.

[0007] Preferably, a fixing pin is inserted at the connection between the fixing plate and the clamping arm, and the clamping arm is installed at the upper end of the fixing plate.

[0008] Preferably, the bracket forms a rotating structure with the mounting frame via a hydraulic telescopic rod, and the diagonal telescopic rod is installed along both sides of the mounting frame.

[0009] Preferably, a rotating arm is movably connected at the connection between the mounting bracket and the inclined telescopic rod, and the rotating arm and the inclined telescopic rod are fixedly connected.

[0010] Preferably, a connector is fixed at the connection between the inclined telescopic rod and the fixed rod, and the connector and the fixed rod are movably connected.

[0011] Preferably, the upper end of the inclined telescopic rod is movably connected to a mounting frame, and a lifting device is mounted on the top of the upper end of the mounting frame. A hydraulic telescopic rod is movably connected to the middle of the inner side of the mounting frame.

[0012] Preferably, the lifting device is installed and fixed to the injection mold frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are: when the rotary frame for injection mold is used, the support is provided with a waist tightening hole in the middle. Through the mold demolding position, the user can slide the suction cup along the waist tightening hole. This adjustable operation mode makes it convenient for the user to make precise adjustments according to the number of demolded workpieces, and to adjust the position of the suction cup according to different molds, thereby improving the adaptability of the rotary frame and reducing the production cost of enterprises.

[0014] The hydraulic telescopic rod, as the rotation angle control component of the bracket, is distributed along the center position of the bracket. It is pushed out by the hydraulic telescopic rod, and the middle part of the bracket is constrained by the diagonal telescopic rod, thereby meeting the action requirements of the bracket's movement and rotation. This action improves the bracket on the suction cup into a rotatable bracket. When different numbers of rows are required, the direction of the suction cup can be adjusted by rotating the bracket, thus realizing multi-purpose injection molding processing.

[0015] Both sides are equipped with diagonal extension rods to ensure the stability of the support during rotation and prevent it from deviating. At the same time, the diagonal extension rods ensure the stability and rationality of the overall structure, ensuring that the support can rotate safely and meet the requirements for long-term stable use.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a rotating frame for injection molds, including a support 1, a fixed plate 3, a mounting frame 6, and a hydraulic telescopic rod 8. A plurality of suction cups 2 are laid on one side surface of the support 1, and nuts 21 are threadedly connected to the connection between the suction cups 2 and the support 1. The fixed plate 3 is welded to the middle of the support 1 and is positioned at the center of gravity of the support 1. A fixed rod 4 is welded to the lower surface of the fixed plate 3, and inclined telescopic rods 5 are movably connected to both sides of the fixed rod 4. A movable head 81 is welded to the bottom of the hydraulic telescopic rod 8, and a clamping arm 82 is movably connected to the lower end of the movable head 81, with the lower end of the clamping arm 82 embedded in... The fixed plate 3 and the bracket 1 have a waist tightening hole 11 on their inner side, and the suction cup 2 slides along the waist tightening hole 11. The suction cup 2 is fixed to the bracket 1 by a nut 21. The bracket 1 has a waist tightening hole 11 in the middle. Through the mold demolding position, the user slides the suction cup 2 along the waist tightening hole 11. After the suction cup 2 is accurately positioned with the workpiece, the suction cup 2 is fixed to the bracket 1 by the nut 21. This adjustable operation mode allows the user to make precise adjustments according to the number of demolded workpieces and to adjust the position of the suction cup 2 according to different molds, thereby improving the adaptability of the rotating frame and reducing the production cost of the enterprise.

[0023] A fixing pin 83 is inserted at the connection between the fixed plate 3 and the clamping arm 82, and the clamping arm 82 is installed at the upper end of the fixed plate 3. The bracket 1 forms a rotating structure with the mounting frame 6 through the hydraulic telescopic rod 8, and the inclined telescopic rod 5 is installed along both sides of the mounting frame 6. The hydraulic telescopic rod 8 serves as a rotation angle control component for the bracket 1 and is distributed along the center position of the bracket 1. The bracket 1 is pushed out by the hydraulic telescopic rod 8, and the middle part of the bracket 1 is constrained by the inclined telescopic rod 5, thereby meeting the action requirements of the bracket 1 to rotate. This action improves the bracket 1 on the suction cup 2 into a rotatable bracket. When different numbers of rows are required, the direction of the suction cup 2 can be adjusted by rotating the bracket, thus realizing multi-purpose injection molding processing.

[0024] A rotating arm 52 is movably connected to the connection between the mounting bracket 6 and the inclined telescopic rod 5, and the rotating arm 52 is fixedly connected to the inclined telescopic rod 5. A connecting joint 51 is fixedly connected to the connection between the inclined telescopic rod 5 and the fixed rod 4, and the connecting joint 51 is movably connected to the fixed rod 4. The inclined telescopic rod 5 serves as an auxiliary component to constrain and protect the bracket 1. With inclined telescopic rods 5 on both sides, the bracket 1 is ensured to move stably and not easily deviate during rotation. Furthermore, the inclined telescopic rods 5 ensure the stability and integrity of the overall structure. To ensure the safe rotation and long-term stable use of the support frame 1, the upper end of the inclined telescopic rod 5 is movably connected to the mounting frame 6, and the top of the mounting frame 6 is equipped with a lifting device 7. The middle of the inner side of the mounting frame 6 is movably connected to the hydraulic telescopic rod 8. The lifting device 7 is installed and fixed to the injection mold frame. The mounting frame 6 serves as a fixing component to store and fix the lifting device 7 and the hydraulic telescopic rod 8. At the same time, the lifting device 7 serves as an installation component to install and fix the rotating support to the injection mold frame, ensuring that the rotating support is connected and installed to the injection mold frame.

[0025] Working principle: For this type of injection mold, the rotating bracket is first installed and fixed to the injection mold frame using the lifting device 7. At this time, the user controls the hydraulic telescopic rod 8 to push out. Under the action of eccentric force, its fixed plate 3 rotates axially around the center of the fixed rod 4. At the same time, the middle of the bracket 1 is constrained by the inclined telescopic rod 5, and inclined telescopic rods 5 are set on both sides to ensure that the bracket 1 moves stably during rotation. Then, when the bracket 1 rotates to the appropriate position, the suction cup 2 grabs the workpiece by suction through negative pressure. Then, the hydraulic telescopic rod 8 retracts, driving the bracket 1 to return to its original position. Finally, the user can remove the workpiece from the suction cup 2.
