Background Art

[0002] Plastic products are a general term for daily necessities and industrial products made of plastic as the main raw material. The development direction of plastics can be summarized into two aspects. One is to improve performance, that is, to modify existing varieties by various methods to improve their comprehensive performance; the other is to develop functions, that is, to develop polymer materials with physical functions such as light, electricity, and magnetism, so that plastics can have photoelectric effect, thermoelectric effect, piezoelectric effect, etc. The application field of plastic products is gradually expanding, and the shapes of plastic products are also ever-changing. For plastic products with multiple undercuts with different demolding directions, there are special requirements for the mold structure.

When the first slider seat 14 is completely opened and separated from the first undercut of the product, the control column 31 is separated from the second slider seat 22. Under the action of the tension of the second spring 27, the second slider seat 22 moves and separates from the second undercut of the product. Under the action of the tension of the fifth spring 34, the block 32 pops out; during the mold closing process, the square clamping head provided on the block 32 contacts the stepped surface provided on the control column 31 and limits the second slider seat 22 from resetting. After the first slider seat 14 is completely reset, the inclined surface provided on the block 32 contacts the inclined surface provided on the second slider seat 22 and pushes the block 32 to reset. After the block 32 is reset, the control column 31 slides and cooperates with the second slider seat 22, and the second slider seat 22 is reset at the same time.

[0010] The first inclined wedge 16 is provided with a guide post hole, a first inclined surface and a second inclined surface. The guide post hole is in surface contact with the first inclined guide post 18 and is tightly matched. In the mold closing state, the first inclined surface is in surface contact with the first slider seat 14 and is tightly matched with a wedge. During the mold closing process, the first inclined surface applies a thrust to the first slider seat 14 and drives it to reset. In the mold closing state, the second inclined surface is in surface contact with the counter wedge block 19 and is tightly matched with a wedge, which plays a counter wedge limiting role for the first inclined wedge 16.

[0011] The working principle of the mold with a controllable multi-directional sliding mechanism is as follows: the mold opening force applied to the mold by the molding machine and the tension of the sixth spring 8 and the seventh spring 10 are used to realize the separation of the flow channel plate 2 and the first draw plate 3, and the separation of the first draw plate 3 and the fixed mold plate 4. The first shoulder bolt 6 is used to limit the opening distance between the fixed mold bottom plate 1 and the flow channel plate 2, the third shoulder bolt 9 is used to limit the opening distance between the flow channel plate 2 and the first draw plate 3, and the second shoulder bolt 7 is used to limit the opening distance between the first draw plate 3 and the fixed mold plate 4. The first draw plate 3 and the fixed mold plate 4 are separated to drive the control column 31 and the first inclined wedge 16 to make a linear motion along the mold opening direction. The separation of the first inclined wedge 16 and the first slider 13 cancels the wedging force applied by the first inclined wedge 16 on the first slider 13. Under the action of the tension of the first spring 15 and the first inclined guide column 18, the first slider seat 14 slides and breaks away from the first undercut of the product. The ball head top screw 20 contacts and limits the first through groove set on the first slider seat 14. The control column 31 makes a linear motion along the mold direction and presses the second slider seat 2 2 is limited to prevent the second slider seat 22 from sliding. After the first draw plate 3 and the fixed mold plate 4 are completely separated and limited, the control column 31 is separated from the second slider seat 22. Under the tension of the second spring 27 and the action of the second inclined guide column 24, the second slider seat 22 slides and separates from the second undercut of the product. The ball head push rod 28 is used to contact and limit the third through groove set on the second slider seat 22. During the mold closing process, the power of the molding machine is used to guide the first inclined guide column 18 to the first slider seat 14, and the first inclined wedge 16 to the first slider The push of the block seat 14 realizes the reset of the first slider seat 14, and the control column 31 is used to limit the block 32 to realize the delayed reset of the second slider seat 22. The inclined surface set on the block 32 and the thrust of the inclined surface set on the second slider seat 22 are used to realize the reset of the block 32. The restriction of the control column 31 by the reset of the block 32 is cancelled. At the same time, the thrust of the second inclined wedge 26 on the second slider seat 22 realizes the reset of the second slider seat 22. The control column 31 contacts and slides with the second slider seat 22 to realize the reset of the control column 31.

[0012] The beneficial effects of the present invention are as follows: the mold utilizes a controllable multi-directional sliding mechanism. During the mold opening process, no external force is required. The mold opening force and spring tension are driven to promote the first sliding of the first slider, and the control column is used to stop the second slider. After the first undercut of the product is demolded, the second slider slides again and the second undercut is demolded. During the mold closing process, the mold closing force, the control column and the clamping block are used in coordination to achieve the first reset of the first slider and the later reset of the second slider, thereby solving the problems existing in the molding mold of plastic products provided with multiple undercuts with different demolding directions, saving mold costs, simplifying mold structures, protecting mold components, ensuring that the mold opening work is stable and reliable, enabling the product to be demolded smoothly and meet technical requirements and use requirements, effectively utilizing mold space, and improving production efficiency.
