Description

Technical Field

[0001] This utility model belongs to the technical field of mold performance testing, specifically relating to a mold ejection testing device. Background Technology

[0002] In the field of industrial manufacturing, plastic products are usually processed using injection molds and injection molding machines. In order to make plastic products easy to demold from the plastic mold, the plastic mold is equipped with an ejection structure for ejecting the plastic products. In order to ensure that the plastic mold can work properly after being assembled on the injection molding machine, the ejection structure must be tested before using the plastic mold.

[0003] The conventional testing method for ejector structures involves inverting the plastic mold and striking the ejector structure with a rod-like object to cause the ejector component to protrude from the mold cavity, thus testing for potential problems. The issue is that this method cannot ensure the ejector pin remains stationary in a specific position within the mold, and the ejector pin cannot continuously and systematically perform cyclic ejection and resetting operations. Therefore, it is difficult for testers to test and observe the different ejection positions of the ejector component within the mold cavity, making it difficult to detect hidden problems in the ejector structure in a timely manner. This makes it difficult to guarantee the proper functioning of the plastic mold when assembled on the injection molding machine. Furthermore, if a problem with the ejector structure is discovered after the plastic mold is assembled on the injection molding machine, the assembly personnel must disassemble the plastic mold from the machine, incurring labor and time costs, increasing labor costs and reducing production efficiency for the company.

[0004] Therefore, further improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to overcome at least one of the shortcomings of the prior art and provide a mold ejection testing device that enables testers to promptly detect hidden problems in the ejection structure of the mold and ensure that the mold can work normally when installed on the injection molding machine.

[0006] To achieve the above objectives, the technical solution provided by this utility model embodiment is as follows:

[0014] The ejection device further includes an ejector rod connecting movable plate, which is disposed between the driving component and the ejector rod component. The movable end of the driving component is connected to the ejector rod component through the ejector rod connecting movable plate.

[0015] The driving components are several in number and are arranged at intervals along the length of the connecting movable plate of the top roller.

[0016] The ejection device further includes a connecting component, which is disposed between the ejection fixing bracket and the mold fixing plate to leave space for the movement of the ejector roller component. The axial dimension of the connecting component is greater than the movement distance of the ejector roller component.

[0017] The connecting components are four in number and are respectively located at the four corners of the ejector fixing bracket.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0031] See Figure 1-8 This mold ejection testing equipment includes a testing frame 1, an ejection device 2, and a control device 3. In this embodiment, the testing frame 1 includes a mold fixing plate 11 and a support base 12. The mold fixing plate 11 is fixed to the top surface of the support base 12 by fastening components. The ejection device 2 is fixed to the bottom surface of the mold fixing plate 11 by fastening components and is used to perform ejection tests on the ejection structure of the mold 4. The control device 3 is fixed to the side of the support base 12 by fastening components and is used to control the operation of the ejection device 2. The control device 3 and the ejection device 2 are electrically connected by wires. When this mold ejection testing equipment is working, the mold 4 is fixed to the top surface of the mold fixing plate 11 by fastening components. The working end of the ejection device 2 extends upward through the mold fixing plate 11 and into the mold 4, abutting against the bottom of the ejection structure of the mold 4. When the control device 3 controls the working end of the ejection device 2 to move upward and approach... The ejection structure of mold 4 extends upwards. When the control device 3 controls the working end of the ejection device 2 to move downwards and away from the ejection structure of mold 4, the ejection structure of mold 4 returns to its original position under gravity. The control device 3 can control the working end of the ejection device 2 to stop moving at any time, allowing the ejection structure of mold 4 to remain in a certain position within mold 4. This facilitates testing and observation of the ejection structure of mold 4 at different positions within mold 4 by the testing personnel. In addition, the control device 3 can control the working end of the ejection device 2 to continuously reciprocate along the vertical direction of the testing equipment, allowing the ejection structure of mold 4 to undergo continuous and regular cyclic ejection and resetting tests before being assembled on the injection molding machine and undergoing trial molding. This enables the testing personnel to promptly eliminate any hidden problems in the ejection structure of mold 4, ensuring that mold 4 can work normally when installed on the injection molding machine.

[0032] In addition, by adopting the above technical solutions for mold ejection testing equipment, it is possible to ensure that all problems of mold 4 are eliminated before assembly and trial molding, avoiding repeated loading and unloading of mold 4 by assembly personnel on the injection molding machine, reducing loading and unloading costs and time of mold 4, reducing the company's production costs and improving the company's production efficiency.

[0033] Furthermore, in this embodiment, the mold fixing plate 11 is provided with an ejection hole 110, a first mounting hole 111, and a second mounting hole 112. Specifically, the ejection hole 110 is a through hole and is located in the middle of the mold fixing plate 11. The diameter of the ejection hole 110 is slightly larger than the radial dimension of the working end of the ejection device 2, so that the working end of the ejection device 2 can pass upward through the mold fixing plate 11. The first mounting hole 111 and the second mounting hole 112 are preferably screw holes and are arranged opposite each other on the left and right sides of the ejection hole 110. The front and rear sides, and the horizontal distance between the first mounting hole 111, the second mounting hole 112 and the center of the mold fixing plate 11 are the same. When the fastening component cooperates with the first mounting hole 111 and acts on the pressure plate, the left and front sides of the mold 4 are pressed against the mold fixing plate 11. When the fastening component cooperates with the second mounting hole and acts on the pressure plate, the right and rear sides of the mold 4 are pressed against the mold fixing plate 11, so as to realize that the mold 4 is fixed on the top surface of the mold fixing plate 11. This can be understood by those skilled in the art.

[0034] Furthermore, in this embodiment, the number of ejection holes 110 is preferably three. Specifically, the three ejection holes 110 are arranged at intervals along the left and right directions of the mold fixing plate 11. The mold ejection test equipment can increase or decrease the working end of the ejection device 2 according to the ejection structure of different molds 4, so that the mold ejection test equipment can be applied to molds 4 with different structures, thereby improving the versatility of the mold ejection test equipment. This is understood by those skilled in the art.

[0035] In this embodiment, the number of first mounting holes 111 is preferably twelve, arranged at intervals from the center of the mold fixing plate 11 outwards. Six of the first mounting holes 111 are located to the left of the ejection hole 110, and the other six are located in front of the ejection hole 110. The number of second mounting holes 112 is preferably twelve, arranged at intervals from the center of the mold fixing plate 11 outwards. Six of the second mounting holes are located to the right of the ejection hole 110, and the other six are located behind the ejection hole 110. The mold fixing plate 11 can fix molds 4 of different sizes. The first mounting holes 111 and second mounting holes 112 near the center of the mold fixing plate 11 can fix relatively small molds 4, and the first mounting holes 111 and second mounting holes 112 far from the center of the mold fixing plate 11 can fix relatively large molds 4. This allows the mold ejection test equipment to be adapted to molds 4 of different sizes, further improving the versatility of the mold ejection test equipment, which will be understood by those skilled in the art.

[0036] Furthermore, in this embodiment, the ejection device 2 includes an ejection fixing bracket 21, an ejector roller component 22, and a driving component 23. Specifically, the ejection fixing bracket 21 is fixed to the bottom surface of the mold fixing plate 11 by fastening components. The driving component 23 is preferably a cylinder and is arranged vertically. Its fixed end is installed on the ejection fixing bracket 21 by fastening components. The ejector roller component 22 is in the shape of a round rod, and its diameter is smaller than the size of the ejection hole 110 and the size of the through hole on the mold 4 that connects to its ejection structure. Its bottom end is fixed to the movable end of the driving component 23, so that the ejector roller component 22 moves back and forth in the vertical direction through the driving component 23. Its top end is the working end of the ejection device 2 and extends upward out of the mold fixing plate 11 and into the mold 4 and abuts against the bottom of the ejection structure of the mold 4, so that the ejection structure of the mold 4 moves back and forth in the vertical direction through the ejector roller component 22. Through the above technical solution, the ejection device 2 can perform ejection testing on the ejection structure of the mold 4, which can be understood by those skilled in the art.

[0037] Furthermore, the ejector device 2 also includes an ejector rod connecting movable plate 24. Specifically, in this embodiment, the ejector rod connecting movable plate 24 is disposed between the driving component 23 and the ejector rod component 22 and is fixedly connected to the movable end of the driving component 23 and the bottom end of the ejector rod component 22 respectively through a threaded structure or other connection methods. Through the above technical solutions, the movable end of the driving component 23 and the ejector rod component 22 are fixedly connected, which can be understood by those skilled in the art.

[0038] Furthermore, in this embodiment, the number of driving components 23 is preferably two, and they are arranged at intervals along the length direction of the connecting movable plate 24 of the ejector roller. Through the above technical solution, the simultaneous operation of multiple driving components 23 can ensure that the ejection device 2 has sufficient thrust to test the ejection structure of the mold 4, and can to a certain extent ensure the test effect of the mold ejection test equipment on the ejection structure of the mold 4. This can be understood by those skilled in the art.

[0039] Furthermore, the ejection device 2 also includes a connecting component 25. Specifically, in this embodiment, the connecting component 25 is preferably a connecting column and is disposed between the ejection fixing bracket 21 and the mold fixing plate 11. The axial dimension, i.e. the length dimension, of the connecting component 25 is greater than the moving distance of the ejector roller component 22, so that there is space between the ejection fixing bracket 21 and the mold fixing plate 11 through the connecting component 25 for the ejector roller component 22 to move up and down. This ensures that the ejector roller component 22 has sufficient moving distance to extend upward out of the mold fixing plate 11 and perform ejection testing on the ejection structure of the mold 4, or to retract downward into the mold fixing plate 11 so that the mold 4 can be disassembled from the mold fixing plate 11. This is something that those skilled in the art can understand.

[0040] Furthermore, in this embodiment, the number of connecting components 25 is preferably four, and they are respectively arranged at the four corners of the ejection fixing bracket 21. Through the above technical solution, the ejection fixing bracket 21 can be more stable when connected to the mold fixing plate 11 through the connecting components 25, which can ensure the stability of the ejection device 2 during operation to a certain extent. This is understandable to those skilled in the art.

[0041] Further, in this embodiment, the control device 3 includes a control board 31, a control box 32, an emergency stop switch 33, a power switch 34, an indicator light 35, and a control knob 36. Specifically, the control box 32 is fixed to the side of the support base 12 by fastening components, the control board 31 is fixed in the inner cavity of the control box 32, the emergency stop switch 33 is preferably a mushroom-shaped push-button switch, one of which is located on the control box 32, its control end is located on the front face of the control box 32, and its power connection end is located in the inner cavity of the control box 32, for emergency disconnection of the equipment's power supply. The power switch 34 is preferably a toggle switch, one of which is located on the control box 32, its operating end is located on the front face of the control box 32, and its power connection end is located in the inner cavity of the control box 32, for turning the main power supply of the equipment on or off. The indicator light 35 is located on the control box 32. Two control knobs 36 are arranged at intervals along the vertical direction of the control box 32. Their display ends are located on the front surface of the control box 32, and their power connection ends are located in the inner cavity of the control box 32. They are used to display whether the device is powered on and the working status of the device. Two control knobs 36 are arranged at intervals along the vertical direction of the control box 32. Their control ends are located on the front surface of the control box 32, and their power connection ends are located in the inner cavity of the control box 32. They are used to control the ejector device 2. The emergency stop switch 33, power switch 34, indicator light 35, and control knobs 36 are electrically connected to the control board 31. The control board 31 is electrically connected to the ejector device 2 and the external power supply. Through the above technical solution, the control device 3 can observe the working status of the ejector device 2 and control the ejector device 2. Those skilled in the art can understand this.
