The core is an important tool for rubber profiles in the vulcanization process. After the profile is vulcanized, the core needs to be extracted from the profile.

[0003] At present, the extraction of mold cores is mainly done manually. There is no automated equipment, and the mold cores in rubber profile products need to be manually extracted. Specifically, 2 to 4 people are required to cooperate in the operation, one person is responsible for fixing one end of the mold core, and the other is responsible for pulling the product on the mold core. When encountering products that are difficult to demold, other people are required to assist. This method is not only time-consuming and labor-intensive, but also labor-intensive, and easily causes physical burden on workers. It also increases the labor cost of the enterprise; and manual operation is prone to operational errors, resulting in the cracking of rubber profile products, affecting production efficiency and product quality.

[0038] Embodiment 1:

[0039] like Figure 1 and Figure 2 As shown, the present embodiment provides a device for automatically extracting a core of a rubber profile, comprising a stand 1, the stand 1 being a rectangular parallelepiped, the four side surfaces and the bottom surface of the stand 1 being closed structures, a portion of the top surface being a closed structure, and the other portion being an open structure, the stand 1 being provided with a plurality of clamping pads 2, a plurality of clamping blocks 3, a core extraction mechanism and an automatic control system 4, the rubber profile 7 being placed between the clamping pads 2, the core extraction mechanism being connected to one end of the core of the rubber profile 7, a plurality of mounting holes being provided in the closed structure portion of the top surface of the stand 1, a plurality of electrical systems 5 being provided in the stand 1, the tops of the electrical systems 5 being connected to telescopic rods 6, the telescopic rods 6 extending vertically upward to the outside of the stand 1 through the mounting holes, and being connected to the clamping blocks 3, and one electrical system 5 corresponding to one clamping block 3.

[0040] Among them, the clamping block 3 is controlled by the electrical system 5. The clamping force of the clamping block 3 can be adjusted according to the different cross-sectional configurations, sizes and lengths of the rubber profile 7, so as to improve the accuracy of the operation. The clamping force of each clamping block 3 is 300-600N. The number of clamping blocks 3 can also be automatically / manually matched according to the length of the rubber profile 7, so as to improve the flexibility of the operation. In this embodiment, in order to match the rubber profile 7 products within the length range of 500-2500mm, four clamping blocks 3 are set to improve the compatibility of the device, and the four clamping blocks 3 are arranged at equal intervals in the horizontal direction.

[0041] Guide telescopic rods are vertically arranged on both sides of the telescopic rod 6, one end of the guide telescopic rod is fixed to the bottom of the clamping block 3, and the other end is fixed to the top of the stand 1. The electrical system 5 drives the telescopic rod 6 to extend and retract, thereby driving the clamping block 3 to move up and down along the guide telescopic rod. The telescopic rod 6 and the guide telescopic rod are equidistantly spaced. The telescopic rod 6 is arranged in the middle of the clamping block 3, and the guide telescopic rods are respectively arranged on the left and right sides of the clamping block 3, and the telescopic rod 6 and the guide telescopic rod are both arranged on the rear side of the pressing pad 2.

[0042] Specifically, three clamping pads 2 are equidistantly arranged at the bottom of each clamping block 3 and the top of the corresponding stand 1, and the upper and lower three clamping pads 2 are symmetrically arranged. The clamping pads 2 are fixed by bolts. To ensure that the mold core is smoothly pulled out during the operation of the device, the cross-section of the clamping pad 2 is arc-shaped, which increases the contact area, so that it can be compatible with profile products with different configurations such as hollow P-type, O-type, Ω-type, etc., with a diameter range of 5 to 20 mm and a length of 500 mm to 2500 mm, thereby improving the compatibility of the device.

[0043] In this embodiment, a pure rubber pressing pad 2 with a hardness of 30 is selected to increase the friction between the pressing pad 2 and the rubber profile 7.

[0044] Place the rubber profile 7 on the pressing pad 2 and operate the clamping block 3. The four clamping blocks 3 can clamp and fix at the same time. When the rubber profile 7 to be pulled out of the mold core is short and only one clamping block 3 is needed, the other clamping blocks 3 can still work at the same time. The elasticity of the pressing pad 2 can ensure the service life of the device.

[0045] The electrical system 5 and the core extraction mechanism are respectively connected to the automatic control system 4, which is provided with a control panel so that the entire core extraction process can be automated, thereby reducing labor intensity and improving production efficiency. During specific implementation, the rubber profile 7 is placed in the area to be extracted of the compression pad 2, and one-touch operation can be performed through the operation on the control panel of the automatic control system 4, or step-by-step operation can be performed according to actual conditions.

[0046] like Figure 3 and Figure 4 As shown, the core extraction mechanism is arranged at the open structure on the top surface of the stand 1, including a hydraulic component 8, a connecting pin 9, a track gear 10 and a guide track 11. The guide track 11 is fixed to the top of the stand 1 by bolts. The hydraulic component 8 is arranged below the guide track 11 in the stand 1. The hydraulic component 8 provides a 3000N pulling force for the core extraction process, and controls the speed to ensure that the core is extracted at a uniform speed. The track gear 10 is arranged in the guide track 11 and connected to the hydraulic component 8. The track gear 10 can reciprocate in the guide track 11. The core extraction mechanism provides a movement path, a latch hole is provided on the top of the hydraulic component 8, a through hole is provided on one end of the core of the rubber profile 7, one end of the connecting pin 9 is fixed to the top of the hydraulic component 8 through the latch hole, and the other end extends vertically upward to the outside of the stand 1, and is connected to one end of the core of the rubber profile 7 through the through hole. The hydraulic component 8 is used to control the extraction of the core, and the extraction speed and extraction length can be controlled to avoid damage to the rubber profile 7. During specific implementation, the automatic control system 4 is used to control the extraction speed and extraction length, and adjust them according to actual needs.

[0047] The mold core of the rubber profile 7 is connected to the mold core extraction mechanism through the connecting pin 9, and then the mold core extraction mechanism is operated to extract the mold core from the rubber profile 7 along the guide track 11, thereby achieving the purpose of extracting the mold core. The automatic control system 4 can control the magnitude of the pulling force according to the actual situation of the product. The whole process only requires a small amount of operation to achieve the extraction of the mold core, thereby improving production efficiency and product quality.

[0048] In order to prevent mechanical damage during operation, safety gratings are arranged around the four clamping blocks 3 as a whole.

[0049] The automatic control system 4 is connected to a warning light 12, which is connected to the safety grating. When the worker's hands enter the range of the safety grating during the clamping process of the device, the warning light 12 will emit a warning sound, and the automatic control system 4 will stop working. When the hands leave the safety grating, the clamping block 3 will resume automatic operation.

[0050] Embodiment 2:

[0051] like Figure 5 As shown, this embodiment provides a method for automatically extracting a rubber profile mold core, the steps are as follows:

[0052] S1: Place the rubber profile 7 whose core is to be extracted on the pressing pad 2 on the top of the stand 1, and connect one end of the core with a through hole to the core extraction mechanism through a connecting pin 9.

[0053] S2: The automatic control system 4 controls the device to automatically operate, so that the clamping block 3 moves downward synchronously, and the rubber profile 7 to be drawn out of the mold core is fixed between the pressing pads 2.

[0054] When the length of the rubber profile 7 to be pulled out of the mold core is short and only one set of clamping blocks 3 is needed, the remaining clamping blocks 3 still work simultaneously, and the elasticity of the clamping pads 2 can ensure the service life of the device.

[0055] S3: The mold core extraction mechanism operates automatically, and the hydraulic component 8 causes the track gear 10 to move in the guide track 11, thereby causing the connecting pin 9 to drive the mold core to move in the guide track 11, thereby extracting the mold core from the rubber profile 7 along the guide track 11.

[0056] The entire process only requires a small amount of operation to extract the mold core, thereby improving production efficiency and product quality.

[0057] The above specific examples are used to illustrate the present invention, which is only used to help understand the present invention and is not intended to limit the present invention. For those skilled in the art, according to the concept of the present invention, some simple deductions, modifications or substitutions can be made.
