Description

Technical Field

[0001] This utility model belongs to the field of molding die technology, and in particular relates to rubber granule molding die. Background Technology

[0002] Rubber products are typically made by processing rubber materials into granules of specific shapes and sizes. Molding dies ensure that each granule has a consistent shape and size, which is crucial for subsequent processing steps such as thermoforming or injection molding. Irregularly shaped granules can lead to uneven distribution during molding, affecting the product's physical properties, such as strength or elasticity. Furthermore, production efficiency is also a consideration. Using molding dies allows for mass production of granules, increasing production speed and reducing material waste. Compared to hand molding or simple cutting, molding dies can produce large quantities of granules faster and more accurately.

[0003] Existing molding dies require replacement with corresponding molding dies when processing rubber granules into different shapes, thus necessitating the design of various types of molding dies, which increases the cost of use. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0005] A rubber granule molding die includes an upper die and a lower die. The upper die has a placement groove, and an inner liner die is placed inside the placement groove. The side wall of the inner liner die has a positioning groove. The side wall of the lower die has a receiving groove that communicates with the placement groove. The receiving groove is equipped with a fixing pin and a magnetic control mechanism. One end of the fixing pin is inserted into the positioning groove, and the other end is fixedly connected to a permanent magnet.

[0006] As a preferred embodiment of the above technical solution, the magnetic control mechanism includes a rotating frame, a permanent magnet is fixedly connected inside the rotating frame, and a rotating shaft is fixedly connected to the end of the rotating frame. The rotating shaft is rotatably connected to the receiving groove, and a positioning hole is provided on the outer side of the rotating frame.

[0007] As a preferred embodiment of the above technical solution, the side wall of the lower mold is provided with a push-pull groove that communicates with the receiving groove. The push-pull groove is equipped with a fixing mechanism, which is plugged into the rotating frame.

[0008] As a preferred embodiment of the above technical solution, the fixing mechanism includes a push-pull plate one, a connecting plate fixedly connected to one side of the push-pull plate one, a push-pull plate two fixedly connected to the connecting plate, a positioning shaft fixedly connected to one side of the push-pull plate two, the positioning shaft being inserted into a positioning hole, and a guide slide rod being movably sleeved on the inner ring of the connecting plate, the guide slide rod being fixed on the side wall of the push-pull groove.

[0009] As a preferred embodiment of the above technical solution, an elastic element is fixedly connected to one side of the connecting plate, and the end of the elastic element away from the connecting plate is fixed to the side wall of the push-pull groove.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model, by changing the magnetic pole of the magnetic control mechanism and cooperating with the permanent magnet, can push the fixing pin to move in the receiving groove. When the fixing pin is inserted into the positioning groove of the inner mold, the inner mold cannot be separated from the lower mold. When the fixing pin is completely separated from the positioning groove, the inner mold can be taken out from the placement groove of the upper mold, so that inner molds of different shapes can be replaced without repeating the production of upper and lower molds, thus reducing the cost of use.

[0017] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] Example

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the rubber granule molding die includes an upper die 11 and a lower die 12. The upper die 11 has a placement groove, and an inner liner die 13 is provided in the placement groove. The side wall of the inner liner die 13 has a positioning groove. The side wall of the lower die 12 has a receiving groove that communicates with the placement groove. The receiving groove is provided with a fixing pin 22 and a magnetic control mechanism. One end of the fixing pin 22 is inserted into the positioning groove, and the other end is fixedly connected to a permanent magnet 23.

[0020] Specifically, by changing the magnetic poles of the magnetic control mechanism and cooperating with the permanent magnet 23, the fixing pin 22 can be pushed to move in the receiving groove. When the fixing pin 22 is inserted into the positioning groove of the inner mold 13, the inner mold 13 cannot be separated from the lower mold 12. When the fixing pin 22 is completely separated from the positioning groove, the inner mold 13 can be taken out from the placement groove of the upper mold 11, so that inner molds 13 of different shapes can be replaced without repeating the production of the upper mold 11 and the lower mold 12, thus reducing the cost of use.

[0021] like Figure 2 and Figure 3 As shown, the magnetic control mechanism includes a rotating frame 20, a permanent magnet 21 is fixedly connected inside the rotating frame 20, and a rotating shaft 24 is fixedly connected to the end of the rotating frame 20. The rotating shaft 24 is rotatably connected to the receiving groove, and a positioning hole 25 is provided on the outer side of the rotating frame 20.

[0022] Specifically, rotating the rotating frame 20 can drive the permanent magnet 21 to rotate together. When the magnetic poles of the permanent magnet 21 and the permanent magnet 23 are the same on the side that are close to each other, they will push the fixing pin 22 into the positioning groove of the inner liner mold 13. When the magnetic poles are different, they will pull the fixing pin 22 away from the inner liner mold 13.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the side wall of the lower mold 12 is provided with a push-pull groove that communicates with the receiving groove. The push-pull groove is equipped with a fixing mechanism, which is inserted and engaged with the rotating frame 20.

[0024] Specifically, the rotating frame 20 can be fixed by a fixing mechanism to prevent the rotating frame 20 from rotating during the injection molding process and affecting the stability of the inner mold 13.

[0025] like Figure 3 As shown, the fixing mechanism includes a push-pull plate 30, a connecting plate 31 is fixedly connected to one side of the push-pull plate 30, a push-pull plate 32 is fixedly connected to the connecting plate 31, a positioning shaft 33 is fixedly connected to one side of the push-pull plate 32, the positioning shaft 33 is inserted into the positioning hole 25, and a guide slide rod 34 is movably sleeved on the inner ring of the connecting plate 31, the guide slide rod 34 is fixed on the side wall of the push-pull groove.

[0026] Specifically, pushing the push-pull plate 30 located outside the lower mold 12 can drive the positioning shaft 33 to move together through the connecting plate 31 and the push-pull plate 32. When the positioning shaft 33 is disengaged from the positioning hole 25, the rotating frame 20 can rotate around the axis of the rotating shaft 24. When the positioning shaft 33 is engaged with the positioning hole 25, the rotating frame 20 will be unable to rotate.

[0027] like Figure 3As shown, an elastic element 35 is fixedly connected to one side of the connecting plate 31, and the end of the elastic element 35 away from the connecting plate 31 is fixed to the side wall of the push-pull groove.

[0028] Specifically, the elastic element 35 uses, but is not limited to, a spring. The force exerted by the elastic element 35 will pull the connecting plate 31 to one side of the rotating frame 20.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
