[0002] In the production of composite casing products using the APG process, the conductive rod needs to be locked in the mold cavity during casting to ensure the position of the product. After casting, the conductive rod needs to be squeezed to demold the product. Specifically, when closing the mold, the operator manually inserts the pin into the mold and determines whether it is in place by knocking; when demolding, the operator manually pulls out the pin and rotates it, then inserts it into the mold to eject the product. After demolding, the operator manually removes the pin from the mold and places it aside for standby. In actual operation, there is a probability of misoperation due to the manual identification of the direction of the plug rod; whether the mold is in place is also judged by the operator's feel and visual inspection, and there is a possibility of misjudgment. When demolding, the operator needs to use a special puller to pull it out, and the steps are cumbersome. Based on this, it is necessary to design an automatic locking and ejection mechanism for epoxy product casting to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0020] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figure 2 As shown, this embodiment provides an automatic locking and ejecting mechanism for epoxy product casting, which is used in epoxy product molding machines, including two groups of cylinders 1, each group of cylinders 1 has a universal ball head 2 fixedly mounted on the end of the output shaft, and a latch connecting plate 3 fixedly mounted on the universal ball head 2, one group of latch connecting plates 3 is mounted with a locking latch 4, and the other group of latch connecting plates 3 is mounted with an ejection latch 5. Due to the presence of the universal ball head 2, even if a slight shake occurs during the process of plugging and unplugging the locking latch 4 and the ejection latch 5, it will not affect the stability, and the cylinder 1 can smoothly complete the action. Specifically, the two groups of cylinders 1 work independently, one group of cylinders 1 drives the locking latch 4 to move up and down through the universal ball head 2 and the latch connecting plate 3 to complete the locking action, and the other group of cylinders 1 drives the ejection latch 5 to move up and down through the universal ball head 2 and the latch connecting plate 3 to complete the ejection action.

[0023] like Figure 3 and Figure 4As shown, the cylinder 1 is installed on a base plate 6, and a magnet 7 is fixedly installed on the output shaft of the cylinder 1. Specifically, the magnet 7 is embedded in the side wall of the output shaft of the cylinder 1. A detection unit 8 is installed at a position corresponding to each cylinder 1 on the base plate 6 to detect whether the extension of the cylinder 1 is in place, so as to determine whether the locking pin 4 or the ejection pin 5 is in place; the detection unit 8 includes a detection rod 801 movably matched with the base plate 6, and the detection rod 801 is made of iron; an elastic rope 802 is connected between the detection rod 801 and the base plate 6. The detection rod 801 and the base plate 6 are movably matched in the horizontal direction. The detection rod 801 is L-shaped. A vertical conductive rod 803 is fixedly installed on the vertical section of the detection rod 801; a power box 804 is fixedly installed on the base plate 6, a power supply is fixedly installed in the power box 804, a speaker 805 is installed on the power box 804, and two conductive blocks 806 are fixedly installed on the side wall of the power box 804 facing the vertical section of the detection rod 801, and the two conductive blocks 806 correspond to the two ends of the conductive rod 803 respectively. The positive pole of the power supply is connected to the speaker 805 through a wire, and the speaker 805 is connected to one of the conductive blocks 806 through a wire; the negative pole of the power supply is connected to the other conductive block 806 through a wire. When the two conductive blocks 806 are in contact with the conductive rod 803, the power supply, the speaker 805, the conductive block 806 and the conductive rod 803 form a series path through the wire, and the speaker 805 will emit a prompt sound.

[0024] by Figure 3 It is explained that in the initial state, the detection rod 801 is located at the rightmost side of its travel. When the cylinder 1 is extended to a predetermined state, the magnet 7 on the cylinder 1 reaches a predetermined position, that is, a position flush with the horizontal section of the detection rod 801. At this time, the suction force of the magnet 7 on the detection rod 801 will cause the detection rod 801 to overcome the tension of the elastic rope 802 and move to the left. The elastic rope 802 is stretched until the conductive rod 803 fits the conductive block 806. At this time, the speaker 805 will emit a prompt sound, and the operator can judge whether the extension action of the cylinder 1 is in place by the sound. After the cylinder 1 shrinks and recovers, the detection rod 801 is no longer affected by the suction force, and it will move to the right and reset under the rebound force of the elastic rope 802.

[0025] like Figure 4 As shown, a limit block 807 for limiting the detection rod 801 is fixedly installed on the base plate 6; to ensure that the detection rod 801 is translated to the right and reset to a predetermined position under the action of the rebound force of the elastic rope 802, and to avoid the situation where it is translated too much to the right and cannot be attracted by the magnet 7. A ball 808 that rolls with the base plate 6 is installed on the horizontal section of the detection rod 801 to reduce the friction force on the detection rod 801 when it is translated.

[0026] The cross section of the conductive rod 803 is rectangular. The surface of the conductive rod 803 that is in contact with the detection rod 801 is covered with an insulating layer, and the surface of the conductive rod 803 facing the conductive block 806 is exposed.

[0027] Example 2

[0028] like Figure 5 and Figure 6 As shown, a round rod 9 is fixedly installed at the bottom of the latch connecting plate 3, and a semicircular plate 10 is fixedly installed at the bottom end of the round rod 9; a circular groove 401 is provided at the top of the locking latch 4, and two symmetrical receiving grooves 402 are provided on the side wall of the circular groove 401, a locking block 11 is slidably installed in the receiving groove 402, and an elastic member 12 is connected between the locking block 11 and the end surface of the receiving groove 402. The end surface of the locking block 11 facing the center of the circular groove 401 includes an inclined part and a vertical part from top to bottom. When the operator installs the locking latch 4, he only needs to hold the locking latch 4 upward and close to the latch connecting plate 3, so that the semicircular plate 10 is inserted into the circular groove 401 until the top surface of the locking latch 4 fits with the bottom surface of the latch connecting plate 3. In this process, the locking block 11 first fits with the semicircular surface of the semicircular plate 10, and translates under the thrust of the semicircular plate 10 to overcome the action of the elastic member 12. When the locking block 11 is separated from the semicircular surface of the semicircular plate 10, the locking block 11 is translated in the opposite direction and reset under the action of the elastic member 12. The lower surface of the locking block 11 fits with the upper surface of the semicircular plate 10. The semicircular plate 10 supports the locking block 11 and the locking latch 4. In this way, when the latch connecting plate 3 is raised or lowered, the locking latch 4 will be driven to rise or fall synchronously. When the locking latch 4 needs to be removed, the operator only needs to rotate the locking latch 4 so that the locking block 11 is separated from the semicircular plate 10, and the locking latch 4 can be pulled out downward. Compared with the traditional bolt fixing, the connection structure in this embodiment is simple to operate and easy to use, and will not get stuck due to deformation after long-term use. It should be noted that the ejector latch 5 also adopts the same structure, which will not be elaborated in detail here.

[0029] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
