DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See Figure 1-5 , the utility model provides the following two technical solutions:

[0027] The first embodiment: a mold pre-reset elastic slider structure, comprising:

[0028] The mold base 1 has a mounting plate 11 fixed at one end thereof, a reset cylinder 12 fixed at one side of the mounting plate 11, linear slide grooves 13 are provided on both sides of the notch of the mold base 1, and limited slide grooves 14 are provided on both sides of the upper surface of the mold base 1.

[0029] Connecting plate 2, connecting plate 2 is connected to the output shaft of reset cylinder 12, and connecting plate 2 is located in the notch on mold base 1, used for connecting mold slider 3, reset cylinder 12 can drive connecting plate 2 to move, sliding plates 21 are fixed to the bottom of both sides of connecting plate 2, sliding plates 21 are adapted to linear slide groove 13, play a role of guiding and limiting, and prevent connecting plate 2 from moving upward, placing grooves 22 are provided on both sides of the top of one end of connecting plate 2, and a clamping plate 23 is arranged in the placing groove 22, and the bottom of clamping plate 23 is connected to the bottom of the placing groove 22 through a first spring 24, and a slide plate 25 is connected to one side of the lower end of clamping plate 23 through a connecting block, and slide plate 25 is located on the inner side of one end of connecting plate 2, and can drive clamping plate 23 to move through slide plate 25, and can drive clamping plate 23 to reset automatically through the first spring 24.

[0030] The mold slider 3 is arranged on the mold base 1, and one side of the mold slider 3 is connected to the connection. Limit sliders 31 are fixed on both sides of the bottom end of the mold slider 3. The limit slider 31 is located in the limit slide groove 14, which plays a guiding role, so that the mold slider 3 maintains linear movement and prevents the mold slider 3 from being separated from the mold base 1. Bumps 32 are fixed on both sides of one side of the mold slider 3. A card slot 33 is opened at the bottom end of the bump 32. The card slot 33 is adapted to the card plate 23 to fix the mold slider 3 to the connecting plate 2.

[0031] The second embodiment is mainly different from the first embodiment in that a groove 15 is opened in the middle of one side of the notch of the mold base 1, and a top column 16 is arranged in the groove 15. A ball is arranged on the top of the top column 16 through a ball groove, and a piston is arranged at the bottom of the top column 16, which reduces the friction between it and the connecting column plate. The lower surface of the mold base 1 is connected to the external oil cylinder through an oil pipe 17, and the oil pipe 17 is connected to the groove 15. The external oil cylinder applies a weak upward pressure on the top column 16 through the oil pipe 17.

[0032] A slot 26 is provided in the middle of the lower surface of the connecting plate 2, and the slot 26 is adapted to the top column 16. When the slot 26 moves to the top of the top column 16, the top column 16 is inserted into the slot 26 under the pressure of the oil cylinder. A pressure sensor 27 is fixed to the middle of the upper surface of the other end of the connecting plate 2. The pressure sensor 27 is electrically connected to the reset cylinder 12. The bottom of the slot 26 extends to the receiving end of the pressure sensor 27. A second spring 29 is provided in the slot 26. One end of the second spring 29 is connected to the pressure sensor 27. The other end of the second spring 29 is connected to a pressing plate 28. When the pressing plate 28 moves upward, the second spring 29 can be pressed. The reaction force generated by the second spring 29 applies pressure to the pressure sensor 27. The pressure sensor 27 detects the change in force data and controls the reset cylinder 12 to stop driving. At the same time, the second spring 29 presses the top column 16 into the groove 15 when the top column 16 loses the upward pressure, thereby releasing the limit of the connecting plate 2. A plurality of guide blocks 210 distributed in a circular array are fixed to the circumferential side of the pressing plate 28, and a plurality of guide grooves 211 distributed in a circular array are provided on the inner wall of the slot 26. The guide block 210 is located in the guide groove 211. The guide block 210 and the guide groove 211 cooperate to enable the pressing plate 28 to maintain vertical up and down movement.

[0033] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0034] When in use, first the reset cylinder 12 drives the mold slider 3 to move through the connecting plate 2. At this time, the external oil cylinder applies a weak upward pressure on the top column 16, so that the top column 16 contacts the lower surface of the connecting plate 2. The ball on the top column 16 reduces the friction between the two until the slot 26 on the connecting plate 2 moves to the top of the top column 16. At this time, the top column 16 is inserted into the slot 26 under pressure, and the pressing plate 28 is lifted upward, so that the second spring 29 is compressed and stressed. The pressure sensor 27 detects the pressure and controls the reset cylinder 12 to stop driving. When the other sliders are reset, the external oil cylinder stops applying pressure. At this time Under the action of the second spring 29, the pressing plate 28 presses the push column 16 into the groove 15 to release the limit of the connecting plate 2. At this time, the pressure sensor 27 detects the pressure change and controls the reset cylinder 12 to start, driving the mold slider 3 to reset, thereby achieving the purpose of resetting different sliders in sequence. When the mold slider 3 is damaged, the slide 25 is moved downward at this time, and the slide 25 drives the card plate 23 to move downward until the card plate 23 is separated from the card groove 33. At this time, the connecting plate 2 can be separated from the mold slider 3, and then the limit slider 31 on the mold slider 3 is separated from the limit slide groove 14 on the mold base 1 to replace the mold slider 3.
