[0002] Rubber product injection molding equipment is an important equipment used to produce rubber products. Since rubber products are usually made of soft materials, using rigid fixtures to remove materials is likely to cause damage to the workpiece, so patches are usually used.

[0003] To this end, Chinese patent publication number CN220052741U discloses a molded plastic part removal device for a rubber gasket injection molding machine. The cleaning plate is aligned with the rubber gasket in the mold through the design of a movable rod, a cleaning rod, a connecting plate, a cleaning plate, a cleaning plate and other mechanisms. The height of the cleaning plate can be adjusted by the action of a hydraulic rod so that the cleaning plate is attached to the surface of the rubber gasket. At this time, a micro motor is started, and the rotation of the micro motor drives the cleaning plate to rotate, and the rotation of the cleaning plate drives the cleaning plate to rotate. The rotation of the cleaning plate drives the cleaning sheet to clean the dust on the surface of the rubber gasket, thereby avoiding the problem of the rubber gasket falling off easily during the removal process.

[0004] However, since rubber products are relatively soft, it is easy to have cleaning dead corners, which affects the adsorption stability. In the process of adsorbing the workpiece, once the workpiece undergoes some deformation under the action of gravity or other external forces, the adsorption force will drop significantly, resulting in unstable adsorption of the workpiece and causing the workpiece to fall off. Summary of the invention

DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Reference Figure 1-Figure 3 A rubber product injection molding device includes a frame 1, on which a lower mold 11 and an upper mold 12 that can be lifted and lowered in a vertical direction are arranged; the injection molding device also includes a material taking frame 2 movably arranged on the frame 1; the material taking frame 2 is provided with a vacuum suction cup 21 and an auxiliary bracket 22, and the auxiliary bracket 22 is arranged in pairs. The material taking frame 2 is also provided with an opening and closing control device 3 for controlling the opening and closing of the auxiliary bracket 22. In the working state, when the vacuum suction cup 21 absorbs the workpiece, the opening and closing control device 3 controls the auxiliary bracket 22 to close, thereby limiting the movement of the workpiece.

[0032] The present invention realizes the function of stable material picking through the vacuum suction cup 21, the auxiliary bracket 22 and the opening and closing control device 3 for controlling the opening and closing of the auxiliary bracket 22 on the material picking rack 2. The workpiece is first adsorbed by the vacuum suction cup 21, and then further supported by the auxiliary bracket 22, so as to prevent the workpiece from falling off from the material picking rack 2 during transportation, thereby solving the problem that the rubber product workpiece is easy to fall off when being transported by traditional injection molding equipment. A mounting frame 13 is movably provided on the frame 1, and a linear drive 131 is provided on the mounting frame 13, and a driving end of the linear drive 131 is connected to the material taking frame 2; a first linear drive assembly 14 for controlling the movement of the mounting frame 13 is also provided on the frame 1, and the first linear drive assembly 14 includes a first rotary drive 141, a first screw 142, a bevel gear 143 and a guide rod 144; the first rotary drive 141 is installed on the frame 1, and the first screw 142 is rotatably installed on the frame 1, and two bevel gears 143 are provided, and the two bevel gears 143 are respectively sleeved on the first screw 142 and the driving end of the first rotary drive 141, and the two bevel gears 143 are meshed and connected, and the guide rod 144 is provided on the frame 1, and the mounting frame 13 is slidably matched with the guide rod 144, and the mounting frame 13 is threadedly connected with the first screw 142, and a conveyor belt 15 for transporting workpieces is provided on the frame 1. The linear drive 131 is preferably an electric push rod 331 or a linear cylinder, and the first rotary drive 141 is preferably a servo motor. A controller for human-machine interaction is provided on the frame 1. The linear drive 131 and the rotary drive are electrically connected to the controller, and the auxiliary bracket 22 is semi-annular. After the workpiece is injection molded, the operator first controls the upper mold 12 to separate from the lower mold 11, and then sends a signal to the first rotary drive 141 through the controller. The first rotary drive 141 drives the first screw 142 to rotate through the bevel gear 143, and the first screw 142 drives the mounting frame 13 threadedly connected thereto to slide along the guide rod 144. When the mounting frame 13 moves to the top of the lower mold 11, a signal is sent to the linear drive 131 through the controller, and the linear drive 131 Drive the material picking rack 2 to move downward, and then use the vacuum suction cup 21 to absorb the workpiece, and then drive the material picking rack 2 to move upward through the linear drive 131. After lifting the workpiece for a distance, control the auxiliary bracket 22 to close through the opening and closing control device 3, and use the auxiliary bracket 22 to further support the workpiece. When the workpiece is absorbed, the auxiliary bracket 22 only restricts the workpiece and does not press the workpiece, thereby avoiding indentations on the workpiece due to pressure. Even if the workpiece falls off the vacuum suction cup 21 during transportation, it will be lifted by the auxiliary bracket 22. The two semi-annular auxiliary brackets 22 can stably lift the workpiece, and cooperate with the first linear drive component 14 to continue to transport the workpiece. After the workpiece is moved to the conveyor belt 15, the workpiece is moved to the specified position through the transmission belt.

[0034] The present invention realizes the function of automatically sensing the adsorption state of the workpiece through the ejector rod 111 and the abutment rod 23, and achieves the effect of automatically controlling the closing of the auxiliary bracket 22 according to the adsorption state of the workpiece. When taking the material, the upper mold 12 is first separated from the lower mold 11, and then the material taking frame 2 is moved to the lower mold 11, and then the workpiece is lifted up by the ejector rod 111, so that the workpiece contacts the adsorption section of the vacuum suction cup 21, and then the workpiece is adsorbed by the vacuum suction cup 21. In this process, the thrust provided by the ejector rod 111 pushes the abutment rod 23 through the workpiece, and the abutment rod 23 is started after being pushed. The opening and closing control device 3 is used to control the closing of the auxiliary bracket 22 to complete the material taking of the workpiece. The abutment rod 23 has little resistance to the upward movement of the workpiece, so it will not crush the workpiece.

When the ejector rod 111 presses the workpiece toward the material picking rack 2, the ejector rod 111 presses the abutment rod 23 into the material picking rack 2 through the workpiece, and the abutment rod 23 drives the control assembly 33. The control assembly 33 overcomes the elastic force of the second elastic member 324 to drive the push block 322 and the locking block 323 to move in a direction away from the locking groove 2211 until the locking block 323 is separated from the locking groove 2211, and the movement restriction of the slide 221 by the locking assembly 32 is released. The slide 221 moves under the elastic force of the first elastic member 31, and the slide 221 drives the two annular auxiliary brackets 22 arranged in pairs to move toward the workpiece, and then the support and restriction of the workpiece are completed by the closing of the two auxiliary brackets 22.

[0041] Reference Figure 7 and Figure 8 The control component 33 includes a push rod 331, which is slidably installed on the material picking rack 2. An inclined groove 3221 is provided on the push block 322.

The slide 221 moves under the elastic force of the first elastic member 31, and the slide 221 drives the auxiliary bracket 22 to move synchronously, and then the workpiece is supported and restricted by the auxiliary bracket 22.
