[0032] The present application will be described in detail below with reference to the drawings and specific embodiments. The present embodiment is implemented on the premise of the technical scheme of the present application, and gives a detailed implementation and specific operation process, but the protection scope of the present application is not limited to the following embodiments.

[0033] Embodiment 1

[0034] For the ejection of the mold as shown in Figure 2 , the present embodiment provides a mold product ejection device as shown in Figure 1 , comprising:

[0035] The strip block 7 and the two sliders 2, one end of the slider 2 is provided with a clamp cooperating with the code module slot 4 on the mold, both sliders 2 are sleeved on the strip block 7 and slide along the strip block 7, and the clamps of the two sliders 2 are oppositely arranged.

[0036] The screw rod 6 and the sleeve rod 1, the sleeve rod 1 passes through one end of the screw rod 6, and the other end of the screw rod 6 is provided with an ejection part, and the central part of the strip block 7 is provided with a threaded hole for the screw rod 6 to pass through.

[0037] By clamping the code module slot 4 of the mold with the clamp, rotating the screw rod 6 can complete the ejection, which is convenient to operate, occupies small space, and when used, the clamp is clamped into the code module slot 4 of the mold, then the position of the slider 2 is adjusted, the distance between the two sliders 2 is matched with the width of the mold, then the screw rod 6 is rotated, and the ejection part pushes against the top stick 3 to realize ejection.

[0038] In one embodiment, the sleeve rod 1 and the screw rod 6 are vertically arranged, so that more labor can be saved

[0039] In one embodiment, the two ends of the strip block 7 are provided with limit pins 5 to prevent the slider 2 from disengaging from the strip block 7.

[0040] In one embodiment, the clamp is L-shaped, which is more portable.

[0041] In addition, the radial section of the strip block 7 is rectangular, and the radial section is perpendicular to the axial direction of the strip block 7, which is more stable and less likely to rotate.

[0042] Implementation Method 2

[0043] In this implementation method, as Figure 3 As shown, in addition to including all the features of Embodiment 1, the device also includes a traction unit for traction of the slider 2. The traction unit includes a lead screw 81 and two nuts 82. The two ends of the lead screw 81 pass through the two sliders 2 respectively. The lead screw 81 is provided with a first threaded section and a second threaded section, as shown. Figure 4 As shown, the threads on the first and second threaded sections are arranged in opposite directions. The two threads are respectively fitted onto the first and second threaded sections and connected to the two sliders 2. By rotating the lead screw 81, the two nuts 82 move in opposite directions, thereby pulling the sliders 2 and causing them to move towards each other. Conversely, when separation is required, simply rotate the lead screw 81 in the opposite direction.

[0044] In one embodiment of this invention, the device further includes a drive motor 83, which is mounted on the strip block 7 via a motor bracket, and its output shaft is connected to a lead screw 81. To improve the smoothness of the traction of the slider 2, two traction units are configured. In this case, as shown... Figure 5 As shown, the output shaft of the drive motor 83 is connected to the lead screw 81 of one of the traction units, and the lead screws 81 of the two traction units are linked by a gear set. In addition, the gear set includes a driving gear and a driven gear with the same number of teeth. The driving gear and the driven gear are respectively sleeved on the two lead screws 81, and the threads on the first threaded sections of the two lead screws 81 are arranged in opposite directions.

[0045] In one embodiment of this invention, the device further includes a sensor and a controller for controlling the drive motor 83 to stop outputting after the caliper clamps the mold. The sensor is located on the surface of one of the calipers contacting the mold coding groove 4 and is connected to the controller, which is connected to the drive motor 83.

[0046] Specifically, the controller and sensor can be designed as follows: the sensor is a photodiode, such as... Figure 6 As shown, the photodiode is placed in a groove on the caliper surface. When the caliper enters the code slot 4, the photodiode is blocked. Furthermore, the controller can be a relay, such as... Figure 7 As shown, under normal circumstances, the caliper without a photodiode is first aligned, and then the manual switch connected in series with the input terminal of the drive motor 83 is switched. Since the input terminal of the relay coil is at a high level, the contacts are in a conductive state, the drive motor 83 starts to work, the lead screw 81 rotates, the nut 82 moves along the lead screw 81, and drives the slider 2 to move in opposite directions. When the caliper with a photodiode enters another code slot 4, the photodiode is turned off. At this time, the input terminal of the relay is at a low level, the contacts are open, and the drive motor 83 stops outputting.
