[0019] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0020] Please see Figures 1-3 The embodiments of this utility model include:

[0021] This utility model discloses an injection mold insert fixture 100, comprising a feeding mechanism 1 and a picking mechanism 2. The picking mechanism 2 is disposed at one end of the feeding mechanism 1. The feeding mechanism 1 is provided with multiple ejection devices 3, and inserts are installed at the outer ends of the ejection devices. The multiple ejection devices consist of an upper ejection device and a lower ejection device, with the upper and lower ejection devices having opposite ejection directions and being arranged longitudinally. In specific implementation, this application is used for negative pressure detection of product picking and insert embedding in deep cavity injection molds. Specifically, after the product produced by the injection mold is removed, the insert on the ejection device is driven into the injection mold. In specific implementation, the fixture is mounted on a robotic arm, which can drive the fixture to move in the mold opening direction and perpendicular to the mold opening direction. It is suitable for molds with high temperatures, avoiding the risk of burns to operators. At the same time, the insert is installed at the outer end of the ejection device, which improves the success rate of insert embedding and shortens the insert embedding time, thereby shortening the injection time of the injection mold.

[0022] The feeding mechanism 1 includes a fixed plate 11 and a left side plate 12 and a right side plate 13 fixedly installed thereon. The upper ejection device and the lower ejection device are respectively located on the upper part of the left side plate 12 and the lower part of the right side plate 13.

[0023] The upper ejection device and the lower ejection device include an upper bracket 31 and a lower bracket 32 ​​fixedly installed on the opposite inner sides of the left side plate 12 and the right side plate 13, and a plurality of ejection components installed on the upper bracket 31 and the lower bracket 32.

[0024] The ejection assembly includes an ejection driver 33 and an ejector rod 34 fixedly mounted thereon. The ejection driver 33 is fixedly mounted to the upper bracket 31 or the lower bracket 32. The outer end of the ejector rod 34 passes through the left side plate 12 or the right side plate 13.

[0025] The ejector driver 33 is a micro-motion cylinder.

[0026] The left side plate 12 and the right side plate 13 are provided with grooves 14 and through holes communicating with the grooves. The grooves are provided with limiting surfaces 141, and the through holes are for the push rod 34 to pass through. Specifically, the shape of the groove matches the insert, the insert is embedded in the groove, and the push rod driven by the push driver pushes the insert embedded in the groove out.

[0027] The upper bracket 31 and the lower bracket 32 ​​have the same structure. The upper bracket 31 includes a mounting plate 311 and an upper upright plate 312 and a lower upright plate 313 that fix the mounting plate 311 to the left side plate 12 or the right side plate 13. The upper upright plate 312 and the lower upright plate 313 are fixed to both ends of the mounting plate.

[0028] The ejector driver 33 is fitted with two fixing pieces 35. When the ejector driver 33 is installed with the mounting plate 311, the two fixing pieces 35 are located on both sides of the mounting plate 311 to fix the ejector driver 33.

[0029] Both the mounting plate of the upper bracket 31 and the mounting plate of the lower bracket 32 ​​are equipped with four ejector assemblies. In specific implementations, this application can be adjusted according to the number of inserts required by the customer's product. The left side plate, the upper bracket, and the ejector assemblies mounted thereon can be assembled into a module. Different modules can be made according to different customer products. When the number and position of the inserts required by the product are changed, the module can be replaced.

[0030] The part-retrieving mechanism 2 includes a rotator 21 fixed to one end of the fixed plate 11. A gripper device 22 is mounted on the rotating end of the rotator 21, and the opening and closing direction of the gripper device 22 is perpendicular to the running direction of the fixture 100. In specific implementations of this application, the rotation and gripping functions of the part-retrieving mechanism can be achieved by combining the rotator and gripper device, or by using a gripper cylinder with a rotation function. The required device can be adopted according to design requirements. Structures with both rotation and gripping functions are within the protection scope of this application.

[0031] Please see Figure 4 This application discloses an injection mold insert fixture 100 for removing products from a negative pressure detection deep cavity injection mold and embedding inserts. The fixture's fixing plate is used in conjunction with a robotic arm at the other end of the mounting and removal mechanism.

[0032] The injection mold includes a fixed mold core, a movable mold core, and a cavity formed between the fixed mold core and the movable mold core. A mold closing device and a negative pressure detection device are symmetrically installed on both sides of the cavity. The mold closing device includes a mold closing fixing block and a mold closing slider. The negative pressure detection device includes a suction component and a vacuum component. The suction component is disposed in the mold closing fixing block and is used to suction and fix multiple inserts. The vacuum component is connected to the suction component and controls the suction and release of the suction component. The product produced by this injection mold is a deep-cavity box with 8 chambers. During injection molding, an insert needs to be embedded in the outer wall of each chamber. There are 4 inserts on each side of the product. The inserts on each side are set on the outer wall of the chamber one chamber apart. Before injection molding, the 8 inserts need to be pre-embedded in the mold closing device. The negative pressure detection device continuously detects whether the inserts have fallen off. If the insert falls off and the negative pressure value exceeds the set range, the system will send a signal to the injection mold. The injection mold will immediately stop and issue an alarm. When it is ensured that the inserts have not fallen off before mold closing, the fixed mold core and the moving mold core close the mold. Polycarbonate liquid is injected into the cavity and then cooled to form the product.

[0033] The robotic arm moves the fixture perpendicular to the mold opening direction of the injection mold to the front of the product, and then moves towards the product. After the gripper of the part-removing mechanism holds the product, the fixture moves perpendicular to the mold opening direction of the injection mold. When the lower ejection device of the fixture is aligned with the suction component of the negative pressure detection system of the mold closing fixing block on one side, the micro-motion cylinder of the fixture ejects the insert on the ejector rod. After the suction component holds the insert, the robotic arm continues to move the fixture perpendicular to the mold opening direction, so that the upper ejection device on the other side is aligned with the suction component of the negative pressure detection system on the corresponding mold closing fixing block. The micro-motion cylinder of the upper ejection device ejects the insert, which is then held by the corresponding suction component.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
