Description

Technical Field

[0001] The utility model relates to the technical field of casting, in particular to a casting mould oil cylinder stroke detection mechanism. Background Art

[0002] In the design of casting molds, we often encounter the situation that the casting has a strange shape and cannot be normally divided. For such castings, the mold design is generally completed by designing a draw block on the mold.

[0003] The movement of the pump block is generally controlled by the oil cylinder and the connecting rod connected to it. Since the mold is in a continuous high temperature state during production, the oil cylinder is heated for a long time, and the oil cylinder often fails, that is, the pump block mechanism cannot move normally, resulting in the phenomenon that the aluminum liquid overflows from the opening position of the mold pump block due to damage to the oil cylinder during the aluminum liquid filling process and the core pulling mold is not in place. There are serious production safety hazards, and because the mold can only be repaired after being removed from the machine, it causes serious production interruptions. Utility Model Content

DETAILED DESCRIPTION

[0033] The specific implementation of the present utility model is described below with reference to the accompanying drawings.

[0034] See also Figures 1 to 4 The casting mold oil cylinder stroke detection mechanism of this embodiment includes a template 1, on which a mold 2 is arranged;

[0035] A linear drive mechanism 8 is provided on one side of the mold 2, and a pumping block 5 is connected to its output end, which is used to form a part of the mold cavity of the mold 2;

[0036] like Figure 2 and Figure 4 As shown, a protrusion 51 is provided on one of the two ends of the drawer 5 perpendicular to its moving direction, and a first guiding inclined surface 511 is provided on the protrusion 51;

[0037] like Figure 3 and Figure 4 As shown, the mold 2 is provided with a guide groove 21 for accommodating a guide rod 4, and a first end of the guide rod 4 is provided with a second guide slope 41 that matches the first guide slope 511;

[0038] like Figure 1 As shown, the template 1 is provided with a fixing member 6, on which a detection switch 7 is provided, which is located near the second end of the guide rod 4;

[0039] See also Figure 5When the linear drive mechanism 8 drives the drawer 5 to move toward the inside of the mold 2, the first guide slope 511 cooperates with the second guide slope 41 to move the guide rod 4 along the guide groove 21 until the second end of the guide rod 4 is sensed in place by the detection switch 7, indicating that the drawer 5 has moved into place.

[0040] like Figure 1 , Figure 3 and Figure 5 As shown, the mold 2 is further provided with a pressing block 3, and the guide rod 4 is provided with a groove 42 into which the pressing block 3 can be inserted. When the guide rod 4 moves, the pressing block 3 is used to limit the guide rod 4.

[0041] like Figure 3 As shown, a first fixed end 43 is provided under the guide rod 4 , a second fixed end 22 is provided in the guide groove 21 , the second fixed end 22 is connected to one end of the spring 9 , and the other end of the spring 9 cooperates with the first fixed end 43 .

[0042] like Figure 4 As shown, the mold 2 is provided with a mounting groove 23 for mounting the pressing block 3.

[0043] like Figure 7 As shown, the fixing member 6 includes a connecting portion 62 and a supporting portion 61 , the connecting portion 62 is used to connect with the template 1 , and the supporting portion 61 is used to install the detection switch 7 .

[0044] Specifically, the connecting portion 62 and the supporting portion 61 are integrally formed or connected via a locking member.

[0045] like Figure 2 , Figure 3 and Figure 6 As shown, a guide plane 52 is also provided on the pull-out block 5, which extends along the moving direction of the pull-out block 5, and one end of the guide plane 52 is connected to the first guide slope 511; the guide plane 52 is used to cooperate with the front end surface 44 of the first end of the guide rod 4, and the front end surface 44 is connected to the second guide slope 41.

[0046] Specifically, the linear drive mechanism 8 is an oil cylinder.

[0047] Specifically, the detection point on the detection switch 7 is directly opposite to the center of the cross section of the guide rod 4 .

[0048] Specifically, the mold 2 is a lower mold.

[0049] The working principle of the utility model is as follows:

[0050] like Figures 5 to 7As shown, the movement direction of the draw block 5 is perpendicular to the movement direction of the guide rod 4. When the draw block 5 is not in place, under the action of the spring 9, the front end face 44 of the first end of the guide rod 4 abuts against the guide plane 52 of the draw block 5. When the linear drive mechanism 8 drives the draw block 5 to move forward (inside the mold), the guide plane 52 on the draw block 5 cooperates with the front end face 44 of the first end of the guide rod 4, and the guide rod 4 remains stationary in the guide groove 21, and the position is fixed.

[0051] like Figure 8 and Fig. 9 As shown, when the linear drive mechanism 8 drives the pumping block 5 to continue to move forward ( Figure 5 The guide rod 4 moves to the right along the guide groove 21 (in the direction of the middle arrow, i.e., moves into the mold cavity) until the first guide slope 511 and the second guide slope 41 cooperate with each other, so that the guide rod 4 moves to the right along the guide groove 21 ( Figure 5 The second end of the guide rod 4 moves toward the direction close to the detection switch 7, and at the same time, one end of the spring 9 is pressed against the first fixed end 43 of the guide rod 4 and compressed. When the second end of the guide rod 4 is sensed by the detection switch 7, the detection switch 7 is triggered to send a signal, indicating that the pumping block 5 moves to the position, and the linear drive mechanism 8 stops, that is, the control of the pumping block movement stroke is realized. At this time, the first guide slope 511 is tightly fitted with the second guide slope 41. The detection switch 7 sends an electrical signal, and the low-voltage equipment starts the casting action after receiving the signal.

[0052] If the pull-out block 5 is not in place, the detection switch 7 will not send out an electrical signal to allow the low-voltage device to work because the guide rod 4 is in place, thereby avoiding production safety hazards such as mold aluminum liquid overflow and abnormal production interruption due to the pull-out block 5 not being in place.

[0053] After pouring is completed, the casting is formed. After production is completed, when the mold is opened, the linear drive mechanism 8 is started, and the drawer 5 moves backward. Under the elastic force of the spring 9, the guide rod 4 moves to the left, and the second end of the guide rod 4 is disengaged from the detection switch 7.

[0054] The utility model accurately controls the stroke of the linear drive mechanism to ensure that the block is moved in place, avoids the problem of production interruption caused by overflow of pouring liquid during pouring and filling due to inadequate movement of the block, and improves the stability of equipment operation and production safety.
