[0029] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the utility model provides a mold box replacement tool for replacing a mold box 5 installed on a base plate 6. A spring piece 51 is provided between the mold box 5 and the base plate 6. The spring piece 51 is used to lock the mold box 5 on the base plate 6. The mold box replacement tool includes: a support plate 1, a pressure plate 2, a baffle 3 and a hand-held part 4.

[0031] Specifically, the two pressing plates 2 are arranged along a first direction (such as Figure 5 The two pressing plates 2 are spaced below the support plate 1, and the two pressing plates 2 are arranged along the second direction (such as Figure 5 The second direction extends in the Y direction) and is perpendicular to the support plate 1, and the second direction is perpendicular to the first direction.

[0032] The baffle plate 3 extends along the second direction, is disposed between the two pressing plates 2, and is perpendicular to the supporting plate 1 and the pressing plate 3 respectively.

[0033] The hand-held part 4 is arranged above the supporting plate 1 .

[0034] The support plate 1, the two pressing plates 2 and the baffle plate 3 together enclose a cavity for accommodating the mold box 5. When the mold box 5 enters the cavity, the two pressing plates 2 can press on the top of the spring sheet 51 respectively to make the spring sheet 51 produce elastic deformation.

[0035] The applicant has fully considered the problems that may arise when the staff replaces the mold box. The applicant inserts the mold box 5 into the cavity surrounded by the support plate 1, the two pressure plates 2 and the baffle plate 3, and uses the pressure plate 2 to press the two ends of the spring sheet 51 to release the lock of the spring sheet 51 on the mold box 5. The applicant then pushes and pulls the mold box replacement tooling along the extension direction of the slide groove 61, so that the baffle plate 3 applies a force to the mold box 5 to drive the mold box 5 to separate from the bottom plate 6, thereby quickly completing the replacement of the mold box 5.

[0036] Specifically, when the mold box 5 needs to be replaced, the mold box 5 is first inserted into the cavity surrounded by the support plate 1, the two pressing plates 2 and the baffle plate 3. Then, the operator holds the handheld portion 4 and presses the mold box replacement tool downward along the Y direction. At this time, the bottoms of the two pressing plates 2 respectively contact the top of the spring sheet 51 and press the two ends of the spring sheet 51 until the spring sheet 51 produces elastic deformation, so as to release the lock of the spring sheet 51 on the mold box 5. Then, the operator pulls the handheld portion 4 along the extension direction of the slide groove 61, and then pushes and pulls the mold box replacement tool. Since the baffle plate 3 is in contact with the mold box 5 at this time, the baffle plate 3 will apply a force to the mold box 5. Therefore, the mold box 5 will move along the extension direction of the slide groove 61 to separate from the bottom plate 6 under the pushing action of the baffle plate 3, so as to realize the replacement of the mold box 5.

[0037] Furthermore, the mold box replacement tooling also includes a push rod 7 and a push plate 8. The push plate 8 is arranged on the inner side of the baffle 3. The baffle 3 is provided with a clearance hole 31. One end of the push rod 7 is connected to the push plate 8, and the other end of the push rod 7 passes through the clearance hole 31 and extends to the outside of the baffle 3.

[0038] The mold box replacement tooling of the utility model can be provided with a push plate 8 and a push rod 7 connected to the push plate 8 on the inner side of the baffle plate 3. When the mold box 5 is tightly engaged with the bottom plate 6, the force applied to the mold box 5 by pushing and pulling the mold box replacement tooling only by the hand-held portion 4 is not sufficient to drive the mold box 5 to separate from the bottom plate 6. The push rod 7 can be used to push the push plate 8, thereby driving the mold box 5 to separate from the bottom plate 6, so as to increase the force applied to the mold box 5 by the mold box replacement tooling.

[0039] Specifically, the mold box 5 is provided with a groove 52, the groove 52 is close to the side where the baffle 3 is located, and the push plate 8 is clamped in the groove 52. The side wall of the groove 52 can fix the push plate 8 to prevent the push plate 8 from moving on the mold box 5.

[0040] Furthermore, the push rod 7 is provided with a first rod body 71 and a second rod body 72 , the first rod body 71 is perpendicular to the second rod body 72 , and one end of the second rod body 72 is connected to the middle part of the first rod body 71 .

[0041] In specific implementation, the other end of the second rod body 72 can be abutted against the push plate 8, or an external thread can be set at the other end of the second rod body 72 (not shown in the figure) so that the second rod body 72 is threadedly connected to the push plate 8 through the external thread to improve the reliability of the connection between the second rod body 72 and the push plate 8.

[0042] The mold box replacement tooling of the utility model can be configured such that the push rod 7 is configured as a first rod body 71 and a second rod body 72, and the first rod body 71 is vertically connected to the second rod body 72. The operator only needs to hold the first rod body 71 to push the baffle 3 and the mold box 5 to move away from the bottom plate 6 for easy operation.

[0043] Furthermore, the bottom of the two pressing plates 2 is provided with a stop surface 21, which is located on the side of the spring sheet 51 away from the baffle 3, and the spring sheet 51 contacts the stop surface 21. Specifically, the bottom of the pressing plate 2 is provided with a protrusion, and the side wall of the protrusion facing the spring sheet 51 is the stop surface 21.

[0044] When the push rod 7 and the push plate 8 are needed to push the mold box 5 away from the bottom plate 6, the stop surface 21 can prevent the spring sheet 51 and the bottom plate 6 from moving along with the mold box 5, so that the mold box 5 can be smoothly separated from the bottom plate 6, thereby improving the operational reliability.

[0045] In some embodiments, the support plate 1 is provided with an observation port 11 so that the operator can observe the clamping state of the mold box 5 during the mold box replacement process.

[0046] It should be noted that, in the examples and description of the present utility model, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
