[0042] For details, please refer to Figures 1 to 8 , an embodiment of the present application provides a snap machine. The snap machine includes a fixing member 10, a first sliding member 20 and a limiting member 40. Along a first direction, the first sliding member 20 is slidably connected to the fixing member 10. Along a second direction, the first sliding member 20 is slidably connected to the limiting member 40, and the limiting member 40 is configured to follow the first sliding member 20 to slide along the first direction. Among them, the first direction is perpendicular to the second direction. One of the first sliding member 20 and the limiting member 40 is configured with a limiting groove 210. The limiting groove 210 extends along the second direction. The limiting groove 210 has a distal end away from the fixing member 10. The other of the first sliding member 20 and the limiting member 40 is configured with a limiting column 410. The limiting column 410 is slidably connected in the limiting groove 210. When the limiting column 410 abuts against the distal end, the first sliding member 20 and the fixing member 10 are mutually fitted or spaced apart.

[0043] In some embodiments, by constructing the limiting groove 210 in one of the first sliding member 20 and the limiting member 40, and constructing the limiting column 410 in the other, the limiting column 410 is slidably connected in the limiting groove 210. Based on the extension of the limiting groove 210 along the second direction, and when the limiting column 410 abuts against the distal end of the limiting groove 210, the first sliding member 20 and the fixing member 10 are separated from each other or spaced apart. In this way, it is possible to prevent the first sliding member 20 from colliding with the fixing member 10 to generate abnormal noise, and to prevent unnecessary maintenance work.

[0044] It is understandable that the first sliding member 20 can slide along the first direction to form a relative movement between the first sliding member 20 and the fixing member 10. Based on this connection mode, when the button machine is applied to the injection molding machine, the ejection of the product after core pulling can be realized to achieve automatic demoulding. The first sliding member 20 slides along the second direction on the limit member 40 to make the first sliding member 20 approach or move away from the fixing member 10.

[0045] The limiting groove 210 extends along the second direction. After the limiting column 410 is slidably installed in the limiting groove 210, the sliding direction of the first sliding member 20 on the limiting member 40 can be limited by the sliding connection between the two, so as to ensure that the first sliding member 20 and the limiting member 40 can only form relative movement in the second direction. The extension length of the limiting groove 210 is controlled to a certain extent so that a reasonable gap is maintained between the distal end of the limiting member 40 and the fixing member 10. Therefore, when the limiting column 410 abuts against the distal end, the first sliding member 20 and the fixing member 10 are mutually fitted or spaced, thereby preventing the first sliding member 20 and the fixing member 10 from colliding and generating abnormal noise.

[0046] In some embodiments, when the limiting column 410 abuts against the distal end, the first sliding member 20 and the fixing member 10 fit each other. This corresponds to the first sliding member 20 and the fixing member 10 just being in contact, but there is no relative force between the first sliding member 20 and the fixing member 10. Therefore, during the resetting process of the first sliding member 20, when the limiting column 410 abuts against the distal end after the first sliding member 20 is reset, the first sliding member 20 does not collide with the fixing member 10, thereby preventing the first sliding member 20 from colliding with the fixing member 10 and generating abnormal noise.

[0047] In some embodiments, when the limiting column 410 abuts against the distal end, the first sliding member 20 is spaced apart from the fixing member 10. Corresponding to the fact that there is still a certain distance between the first sliding member 20 and the fixing member 10, there is no interaction force at all between the first sliding member 20 and the fixing member 10. Therefore, during the resetting process of the first sliding member 20, when the limiting column 410 abuts against the distal end after the first sliding member 20 is reset, the first sliding member 20 does not collide with the fixing member 10, thereby preventing the first sliding member 20 from colliding with the fixing member 10 and generating abnormal noise.

[0048] like Figure 3 and Figure 4 As shown, in some embodiments, a limiting groove 210 is configured on a side of the first sliding member 20 facing the limiting member 40, and a limiting column 410 is configured on a side of the limiting member 40 facing the first sliding member 20. When the first sliding member 20 is slidably connected to the limiting member 40, the limiting column 410 is also slidably disposed in the limiting groove 210.

[0049] Specifically, a threaded hole can be constructed on the side of the stopper 40 facing the first sliding member 20, an external thread can be constructed on the outer surface of one end of the stopper column 410, the stopper column 410 can be threadedly installed in the threaded hole, and a portion of the stopper column 410 can pass through the threaded hole. In this way, the portion of the stopper column 410 passing through the threaded hole can be slidably connected to the slide groove of the first sliding member 20, so that the sliding assembly and sliding guide of the two can be achieved.

[0050] like Figure 4 As shown, the limiting column 410 can be a cylinder, an elliptical column, a square column, etc. It is sufficient to ensure that the limiting column 410 can be slidably connected with the limiting groove 210. The size of the limiting column 410 can also be reasonably selected based on the size of the limiting groove 210 to ensure that the two can play a sliding guiding effect.

[0051] Among them, one end of the limiting groove 210 close to the fixing member 10 can form a mounting notch on the first sliding member 20. Therefore, when the limiting member 40 and the first sliding member 20 are assembled, the limiting column 410 can be assembled from the mounting notch to the limiting groove 210, so as to realize the sliding assembly between the limiting column 410 and the limiting groove 210.

[0052] In some embodiments, a limiting column 410 is configured on the side of the first sliding member 20 facing the limiting member 40, and a limiting groove 210 is configured on the side of the limiting member 40 facing the first sliding member 20. When the first sliding member 20 is slidably connected to the limiting member 40, the limiting column 410 is also slidably disposed in the limiting groove 210.

[0053] It should be noted that if Figure 1 As shown, the first direction referred to in the embodiment of the present application is the height direction of the fixing member 10 , and the second direction is the thickness direction of the fixing member 10 .

[0054] In some embodiments, the trigger further includes a second sliding member 30. Along the first direction, the second sliding member 30 is slidably connected to the fixing member 10. The second sliding member 30 is configured to abut against the first sliding member 20 so that the first sliding member 20 follows the second sliding member 30 to slide along the first direction. The fixing member 10 is configured with a first driving surface 110. The first sliding member 20 is configured with a second driving surface 220. The second driving surface 220 is configured to drive the first sliding member 20 to slide along the second direction under the action of the first driving surface 110 so that the first sliding member 20 is away from the second sliding member 30.

[0055] The second sliding member 30 slides on the fixing member 10 along the first direction, thereby driving the first sliding member 20 to slide along the first direction. When the first driving surface 110 contacts the second driving surface 220, the first sliding member 20 will slide along the second direction on the basis of sliding along the first direction, so that the first sliding member 20 gradually moves away from the second sliding member 30. When the first sliding member 20 and the second sliding member 30 move away from each other, so that the second sliding member 30 and the first sliding member 20 are no longer in contact, the second sliding member 30 will no longer be able to drive the first sliding member 20 to slide along the first direction. At this time, the second sliding member 30 slides alone along the first direction. In this way, the second sliding member 30 and the first sliding member 20 can achieve two-stage sliding. After applying it to the mold, the product can be first core-pulled and then ejected, ensuring that the product can fall off the mold.

[0056] It can be understood that before the first driving surface 110 and the second driving surface 220 contact, along the first direction, the second sliding member 30 and the first sliding member 20 have a contact area on one side facing each other. After the first driving surface 110 and the second driving surface 220 contact each other, the first sliding member 20 will gradually move away from the second sliding member 30, and at this time, the contact area will continue to decrease. As the area of ​​the contact area decreases to zero, the second sliding member 30 and the first sliding member 20 will no longer be connected, and at this time, the second sliding member 30 will no longer be able to drive the first sliding member 20 to slide along the first direction.

[0057] by Figure 1 From the perspective of, when the second sliding member 30 slides upward, since the second sliding member 30 and the first sliding member 20 are in contact, the second sliding member 30 can drive the first sliding member 20 to slide upward as well. After the second sliding member 30 and the first sliding member 20 slide upward, so that the first driving surface 110 and the second driving surface 220 begin to cooperate with each other, the first sliding member 20 can be driven to slide in a direction away from the second sliding member 30. Before the area of ​​the contact area is completely reduced to zero, the second sliding member 30 slides upward, and the first sliding member 20 slides upward and to the left. When the area of ​​the contact area is reduced to zero, the connection between the second sliding member 30 and the first sliding member 20 is separated. In the above two movement processes, the core pulling action can be completed. At this time, the second sliding member 30 can continue to slide upward, and the first sliding member 20 will stop moving. In this process, the ejection and demolding action of the product can be completed.

[0058] like Figure 2 As shown, in some embodiments, the fixing member 10 is constructed with a side wall 120 extending toward the first sliding member 20, and the side walls 120 are arranged in two intervals to form a first sliding groove 130 on the fixing member 10, and the second sliding member 30 is slidably installed in the first sliding groove 130.

[0059] Based on constructing two spaced-apart side walls 120 on the fixing member 10, the side walls 120 extend toward the direction of the first sliding member 20. The two side walls 120 can form a first slide on the fixing member 10, and the second sliding member 30 is slidably installed in the first slide groove 130 to achieve a sliding connection between the second sliding member 30 and the fixing member 10.

[0060] The side walls 120 extend along the first direction for a certain length, and the side walls 120 have a certain width in the second direction. The spacing between the two side walls 120 is the same as the width of the second sliding member 30 .

[0061] like Figure 2 and Figure 3 As shown, in some embodiments, the side wall 120 has a first side close to the first sliding member 20 and a second side away from the first sliding member 20, the first driving surface 110 is configured on the first side, the first driving surface 110 includes a first abutting surface 140, a first inclined surface 150 and a second abutting surface 160 connected in sequence, the distance between the first abutting surface 140 and the second side is D1, the distance between the second abutting surface 160 and the second side is D2, satisfying: D1<D2, the second driving surface 220 includes a third abutting surface 230 and The second inclined surface 240 is inclined along the direction from the first abutting surface 140 to the second abutting surface 160, and the second inclined surface 240 is inclined in the direction away from the side wall 120, wherein the first sliding member 20 has a first state and a second state, in the first state, the third abutting surface 230 abuts against the first abutting surface 140, and in the second state, the third abutting surface 230 abuts against the second abutting surface 160, and the second inclined surface 240 is configured to drive the first sliding member 20 to switch from the first state to the second state under the action of the first inclined surface 150.

[0062] Since the distance D1 between the first abutting surface 140 and the second side is smaller than the distance D2 between the second abutting surface 160 and the second side, the thickness of the side wall 120 at the location of the first abutting surface 140 is smaller than the thickness of the location of the second abutting surface 160. The second side is a plane, and when the first sliding member 20 slides along the first driving surface 110, the first inclined surface 150 and the second inclined surface 240 cooperate to drive the first sliding member 20 to move in a direction away from the second sliding member 30.

[0063] It is understandable that in the first state, the third abutting surface 230 abuts against the first abutting surface 140, and at this time, the second inclined surface 240 is away from the first inclined surface 150. As the sliding of the second sliding member 30 drives the first sliding member 20 to slide, the second inclined surface 240 will gradually approach the first inclined surface 150. After the second inclined surface 240 abuts against the first inclined surface 150, the second sliding member 30 can drive the first sliding member 20 to slide along the first direction while also making the first sliding member 20 slide along the second direction. After the second inclined surface 240 and the first inclined surface 150 are separated from each other, the second sliding member 30 and the first sliding member 20 will also separate from each other in the second direction. At this time, the third abutting surface 230 will abut against the second abutting surface 160, so that the first sliding member 20 switches to the second state. Then, the second sliding member 30 slides alone along the first direction. Thus, the second sliding member 30 and the first sliding member 20 can realize two-stage sliding. After being applied to the mold, the core pulling action and the ejection and demolding action can be performed in sequence.

[0064] like Figure 1 and Figure 3 As shown, in some embodiments, the limiting member 40 is formed with a second sliding groove 420 , the second sliding groove 420 extends along the second direction, and at least a portion of the first sliding member 20 is slidably connected in the second sliding groove 420 .

[0065] The second sliding groove 420 extends along the second direction, and at least a portion of the first sliding member 20 is slidably installed in the second sliding groove 420 to achieve sliding installation between the first sliding member 20 and the limiting member 40 in the second direction.

[0066] It is understandable that when the second sliding member 30 and the first sliding member 20 abut against each other, at least a portion of the first sliding member 20 passes through the second slide groove 420, so that the second sliding member 30 and the first sliding member 20 have a certain abutting area in the second direction. When the second sliding member 30 and the first sliding member 20 are separated from the abutting, the first sliding member 20 is completely retracted into the second slide groove 420.

[0067] Please continue reading Figure 3 and Figure 4 In some embodiments, a recessed portion 430 is formed on the groove wall of the second sliding groove 420 , and the first sliding member 20 is configured with an outer protrusion 250 , and at least a portion of the outer protrusion 250 is slidably connected in the recessed portion 430 .

[0068] Based on the recessed portion 430 being constructed on the groove wall surface of the second slide groove 420, and the convex portion 250 being constructed outside the first sliding member 20, at least part of the convex portion 250 is slidably connected to the recessed portion 430, so that the position-limiting member 40 and the first sliding member 20 are limited in the first direction through the cooperation of the convex portion 250 and the recessed portion 430, and relative movement of the position-limiting member 40 and the first sliding member 20 in the first direction is prevented. In addition, the position-limiting member 40 can follow the first sliding member 20 to move in the first direction.

[0069] Wherein, a recessed portion 430 may be formed on both groove walls of the second slide groove 420, and the recessed portion 430 extends along the second direction. The convex portion 250 on the first sliding member 20 is adapted to the recessed portion 430. The extension length of the convex portion 250 may be the same as the extension distance of the first sliding member 20 in the second direction. Thus, when the second sliding member 30 and the first sliding member 20 abut against each other, at least a part of the convex portion 250 passes through the recessed portion 430. When the second sliding member 30 and the first sliding member 20 are separated from each other, the convex portion 250 is completely retracted into the recessed portion 430.

[0070] like Figure 2 As shown, in some embodiments, the first side is further configured with a stopper 170 , and the stopper 170 is configured to abut against the first sliding member 20 and / or the limiting member 40 .

[0071] The stopper 170 can prevent the first sliding member 20 and the limiting member 40 from falling off from below the fixing member 10 , thereby achieving a limiting and stopping effect.

[0072] In some embodiments, a mounting hole 260 is constructed on the side of the first sliding member 20 facing away from the second driving surface 220, and an elastic member 270 is provided in the mounting hole 260. At least a portion of the elastic member 270 passes through the mounting hole 260 and abuts against a fixed plate 50. The elastic member 270 is configured to drive the first sliding member 20 to switch from the second state to the first state.

[0073] like Figures 5 to 7 As shown, during the process of the first sliding member 20 switching from the first state to the second state, the first sliding member 20 switches from the third abutting surface 230 abutting against the first abutting surface 140 to the third abutting surface 230 abutting against the second abutting surface 160. At this time, the first sliding member 20 slides toward the fixing plate 50 to shrink the elastic member 270. The elastic force applied to the first sliding member 20 by the shrinking elastic member 270 can ensure the reliability of the abutment between the third abutting surface 230 and the second abutting surface 160, so that the positions of the first sliding member 20 and the limiting member 40 are fixed.

[0074] Please continue reading Figures 5 to 7When the first sliding member 20 needs to switch from the second state to the first state, when the second sliding member 30 gradually returns to the initial position, the elastic member 270 will also gradually extend, thereby pushing the second sliding member 30 toward the first sliding member 20. At this time, the second sliding member 30 will switch from the third abutting surface 230 abutting the second abutting surface 160 to the third abutting surface 230 abutting the first abutting surface 140, thereby switching the slider from the second state to the first state.

[0075] like Figure 8 As shown, an embodiment of the present application further provides a mold. The mold includes a fixed plate 50, a first movable member 60, a second movable member 70, a driving member 80, and the buckle machine in the aforementioned embodiment. Along the first direction, the first movable member 60 and the second movable member 70 are respectively arranged on opposite sides of the fixed plate 50. The driving member 80 is configured to drive the second movable member 70 to move toward or away from the fixed plate 50. Among them, the fixed member 10 is connected to the fixed plate 50, the first sliding member 20 is connected to the first movable member 60, and the second sliding member 30 is connected to the second movable member 70.

[0076] In some embodiments, by constructing the limiting groove 210 in one of the first sliding member 20 and the limiting member 40, and constructing the limiting column 410 in the other, the limiting column 410 is slidably connected in the limiting groove 210. Based on the extension of the limiting groove 210 along the second direction, and when the limiting column 410 abuts against the distal end of the limiting groove 210, the first sliding member 20 and the fixing member 10 are separated from each other or spaced apart. In this way, it is possible to prevent the first sliding member 20 from colliding with the fixing member 10 to generate abnormal noise, and to prevent unnecessary maintenance work.

[0077] When the driving member 80 drives the second movable member 70 away from the fixed plate 50, the position of the fixed plate 50 remains unchanged, and the position of the fixed member 10 does not move. At this time, the second movable member 70 drives the second sliding member 30 to move, drives the second sliding member 30 to slide along the first direction, and makes the second sliding member 30 drive the first sliding member 20 to slide along the first direction. Then the first movable member 60 can also move in the direction away from the fixed plate 50 under the drive of the first sliding member 20. Thus, the first movable member 60 and the second movable member 70 are driven to slide synchronously by the driving member 80, thereby completing the core pulling action.

[0078] When the second driving surface 220 of the first sliding member 20 contacts the first driving surface 110 of the side wall 120, the first sliding member 20 will move away from the second sliding member 30, so that the connection between the second sliding member 30 and the first sliding member 20 is gradually separated. During this process, the first movable member 60 and the second movable member 70 will continue to slide.

[0079] like Figure 6 to Figure 7As shown, when the second sliding member 30 is completely separated from the first sliding member 20, as the driving member 80 continues to drive the second movable part to slide along the first direction, the second movable member 70 and the second sliding member 30 will continue to slide along the first direction, but the second sliding member 30 will no longer drive the first sliding member 20 to slide along the first direction. At this time, the position of the first movable member 60 will be fixed, and the molded product can be ejected out of the mold by the ejector installed on the second sliding member 30, thereby completing the ejection and demolding action.

[0080] After the injection molded product performs the core pulling action and the ejection and ejection action in sequence, the driving member 80 will retract its driving rod, so that the first movable member 60 and the second movable member 70 are gradually reset.

[0081] The fixing member 10 and the fixing plate 50 , the first sliding member 20 and the first movable member 60 , and the second sliding member 30 and the second movable member 70 may all be connected by bolts.

[0082] The embodiment of the present application further provides an injection molding machine, which includes the mold in the above embodiment.

[0083] In some embodiments, by constructing the limiting groove 210 in one of the first sliding member 20 and the limiting member 40, and constructing the limiting column 410 in the other, the limiting column 410 is slidably connected in the limiting groove 210. Based on the extension of the limiting groove 210 along the second direction, and when the limiting column 410 abuts against the distal end of the limiting groove 210, the first sliding member 20 and the fixing member 10 are separated from each other or spaced apart. In this way, it is possible to prevent the first sliding member 20 from colliding with the fixing member 10 to generate abnormal noise, and to prevent unnecessary maintenance work.
