The molds are cut out from the composite panels and assembled together to improve children's hands-on ability and creative thinking.

[0003] The patent document with publication number CN214081754U discloses a cutting device for toy production molds, including a control top plate, a support column, a cutting assembly and a base assembly.

[0015] A production process of a science and innovation teaching combination tool, the process comprising the following steps:

[0016] Step 1: placing the composite sheet for cutting between the first die and the second die, and then moving the first die and the second die closer to each other through the action of the relative movement mechanism, and the first stop block and the second stop block move synchronously with the first die and the second die respectively to clamp the composite sheet;

[0017] Step 2: by cooperating with the moving mechanism, the annular cutter and the movable sleeve ring are moved synchronously with the corresponding first die and the second die respectively. Since the cutting end of the annular cutter is located below the corresponding first stop block, before the first stop block contacts the composite sheet, the annular cutter first contacts the top surface of the composite sheet, and performs cutting and grooving of corresponding shapes at the top of the annular cutter according to the contour of the first stop block;

[0018] Step three: through the action of the movable yielding mechanism, the movable ring moves upward along the surface of the second stop block, thereby driving the corresponding perforating spikes to penetrate the composite board from the bottom surface of the composite board, and the piercing section of the perforating spikes enters the cut groove of the composite board, so that the assembly contour formed by the cutting and the adhesion between the composite boards are perforated multiple times.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When the first stop block contacts the composite sheet, the annular cutter does not penetrate the composite sheet. Then, the movable sleeve moves upward along the surface of the second stop block through the action of the movable yielding mechanism, thereby driving the corresponding perforating spikes to penetrate the composite sheet from the bottom surface of the composite sheet, and the piercing section of the perforating spikes enters the cutting groove of the composite sheet, so that the assembly contour formed by the cutting and the adhesion between the composite sheets are perforated multiple times, and the assembly mold is easily removed from the composite sheet while ensuring an effective connection between the assembly mold and the composite sheet.

[0021] 2. By cooperating with the moving mechanism, the annular cutter and the movable sleeve are moved synchronously with the corresponding first die and second die respectively, and the first movable plate and the second movable plate are moved upward inside the first movable groove and the second movable groove respectively through the action of the movable yielding mechanism, so that the movable sleeve drives the perforating spike to move upward along the second through groove and perforate the composite plate, and the annular cutter moves upward along the first through groove to yield.

[0022] 3. When the first block and the second block move toward each other synchronously and clamp the composite plate, the output shaft of the second motor rotates to drive the limit bar to rotate synchronously, so that the first circular block and the second circular block rotate synchronously, thereby driving the first support block and the second support block to rotate and fall off from the first connecting groove and the second connecting groove respectively, and releasing the movement limit of the first connecting bar and the second connecting bar, so that the first connecting bar and the second connecting bar can move inside the first connecting groove and the second connecting groove respectively.

[0023] 4. The piston shafts of the two hydraulic cylinders move upward synchronously, and drive the rectangular frame to move upward inside the sliding frame, thereby driving the limit bar to rise, so that the first connecting bar and the second connecting bar rise vertically inside the first connecting groove and the second connecting groove respectively, so that the first movable plate and the second movable plate move vertically, so that when the movable sleeve drives the perforating spikes to move upward to perforate the composite plate, the annular cutter moves upward synchronously to make way to prevent the annular cutter and the perforating spikes from contacting.

[0024] 5. The guiding effect of the guide groove on the circular pin causes the sliding baffle to move in the opposite direction, and after the first die moves to the initial position, the sliding baffle completely detaches from the top of the composite sheet and returns to the initial position, so that when the annular cutter detaches from the cutting and grooving position of the composite sheet, the sliding baffle always limits the top of the composite sheet to prevent the annular cutter from being located at the cutting position of the composite sheet and driving the composite sheet to move upward synchronously, thereby ensuring that the composite sheet is always located between multiple limit brackets, thereby improving the unloading efficiency of the composite sheet production and processing.

[0036] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0037] like Figures 1 to 10 The production equipment of a science and technology teaching combination tool shown in the figure comprises a first die 1 and a second die 2, wherein the first die 1 is located above the second die 2, a plurality of first abutment blocks 3 are arranged below the first die 1, and a plurality of second abutment blocks 4 are arranged above the second die 2 (such as Figure 7 and Figure 8 As shown), the positions of the first stop block 3 and the second stop block 4 correspond one to one, and the surface of the first stop block 3 is provided with an annular cutter 5, and the cutting end of the annular cutter 5 is located below the first stop block 3;

[0038] The surface of the second stopper 4 is sleeved with a movable collar 6, and the top of the movable collar 6 is fixedly connected with a plurality of perforated spikes 7, and the top surface of the second stopper 4 is located above the perforated spikes 7;

[0039] A mechanism for moving toward each other is connected between the first die 1 and the second die 2, and a matching mechanism for moving and a movable giving way mechanism are connected to the annular cutter 5 and the movable sleeve ring 6. When the composite board for scientific and creative teaching is cut and molded, the prior art usually directly uses a blade to cut an assembly mold of a corresponding shape on the composite board. When the cutting mold is directly cut and separated from the composite board, the assembly mold is easy to fall off from the slot on the composite board during the subsequent packaging and transportation process, which affects the packaging and the appearance of the product. Only contour cutting is performed to ensure that there is a gap between the composite board and the assembly mold formed by cutting. When the cutting marks are too shallow, it is difficult to remove the cut assembly mold from the composite board, which affects the subsequent use effect. The technical solution can solve the above problems. The specific working method is as follows: the composite board for cutting is placed between the first die 1 and the second die 2, and then the first die 1 and the second die 2 are moved closer to each other through the action of the relative moving mechanism. The first stop block 3 and the second stop block 4 move synchronously with the first die 1 and the second die 2 respectively, and clamp the composite board. The annular cutter 5 and the movable sleeve are moved together by the action of the coordinated moving mechanism. The ring 6 moves synchronously with the corresponding first pressing die 1 and the second pressing die 2 respectively. Since the cutting end of the annular cutter 5 is located below the corresponding first stop block 3, before the first stop block 3 contacts the composite sheet, the annular cutter 5 first contacts the top surface of the composite sheet, and performs cutting and grooving of corresponding shapes on the top of the annular cutter 5 according to the contour of the first stop block 3. When the first stop block 3 contacts the composite sheet, the annular cutter 5 does not penetrate the composite sheet, and then the movable sleeve 6 moves upward along the surface of the second stop block 4 through the action of the movable yielding mechanism, thereby driving the corresponding perforating spike 7 to be removed from the composite sheet. The composite sheet is penetrated on the bottom surface, and the piercing section of the perforating spike 7 enters the cutting groove of the composite sheet, so that the assembly contour formed by cutting and the adhesion between the composite sheet are perforated multiple times. Under the premise of ensuring that there is an effective connection between the assembly mold and the composite sheet, the ease of removing the assembly mold from the composite sheet is improved, and when the movable ring 6 drives the perforating spike 7 to move upward to perforate the composite sheet, the annular cutter 5 moves upward synchronously to make way, reducing the contact and collision between the piercing end of the perforating spike 7 and the cutting end of the annular cutter 5, and extending the service life of the annular cutter 5 and the perforating spike 7.

During operation, when the first die 1 and the second die 2 approach each other through the action of the toward-moving mechanism, the first die 1 and the second die 2 respectively drive the first fixed plate 21 and the second fixed plate 22 to move synchronously, so that the first stopper 3 and the second stopper 4 move toward each other synchronously and clamp the composite sheet material. Through the action of the coordinated moving mechanism, the annular cutter 5 and the movable collar 6 move synchronously with the corresponding first die 1 and the second die 2 respectively, and through the action of the movable yielding mechanism, the first movable plate 23 and the second movable plate 24 move upward inside the first movable groove 17 and the second movable groove 18 respectively, so that the movable collar 6 drives the perforating spike 7 to move upward along the second through-groove 20 and perforate the composite sheet material, and the annular cutter 5 moves upward along the first through-groove 19 to move and yield.

When the first die 1 and the second die 2 move toward each other, the first movable plate 23 and the second movable plate 24 move synchronously with the first die 1 and the second die 2, respectively, so that The first connecting strip 27 and the second connecting strip 28 are moved synchronously, and the first circular block 29 and the second circular block 30 are limitedly slid along the corresponding limit strip 33. After the first stop block 3 and the second stop block 4 move synchronously toward each other and clamp the composite plate, the limit strip 33 is driven to rotate synchronously by the output shaft of the second motor 34, so that the first circular block 29 and the second circular block 30 are rotated synchronously, thereby driving the first support block 35 and the second support block 36 to rotate and fall off from the first connecting groove 25 and the second connecting groove 26 respectively, and releasing the movement limit of the first connecting strip 27 and the second connecting strip 28, so that the first connecting strip 27 and the second connecting strip 28 can move inside the first connecting groove 25 and the second connecting groove 26 respectively.

[0048] Step 2: by cooperating with the moving mechanism, the annular cutter 5 and the movable sleeve 6 are moved synchronously with the corresponding first die 1 and the second die 2 respectively. Since the cutting end of the annular cutter 5 is located below the corresponding first stop block 3, before the first stop block 3 contacts the composite sheet, the annular cutter 5 first contacts the top surface of the composite sheet, and cuts and grooves the corresponding shape at the top of the annular cutter 5 according to the contour of the first stop block 3;

[0049] Step three, through the action of the movable yielding mechanism, the movable ring 6 moves upward along the surface of the second stop block 4, thereby driving the corresponding perforating spike 7 to penetrate the composite board from the bottom surface of the composite board, and the piercing section of the perforating spike 7 enters the cutting groove of the composite board, so that the assembly contour formed by the cutting and the adhesion between the composite boards are perforated multiple times.

[0050] Working principle of the present invention:

[0051] The composite sheet to be cut is placed between the first die 1 and the second die 2, and then the first die 1 and the second die 2 are moved closer to each other through the action of the relative moving mechanism, and the first stop block 3 and the second stop block 4 are moved synchronously with the first die 1 and the second die 2 respectively, and the composite sheet is clamped, and the annular cutter 5 and the movable sleeve 6 are moved synchronously with the corresponding first die 1 and the second die 2 respectively through the action of the coordinated moving mechanism. Since the cutting end of the annular cutter 5 is located below the corresponding first stop block 3, before the first stop block 3 contacts the composite sheet, the annular cutter 5 first contacts the top surface of the composite sheet, and cuts and grooves corresponding to the shape at the top of the annular cutter 5 according to the contour of the first stop block 3.
