Description

Technical Field

[0001] The invention relates to the field of auxiliary demoulding of cylindrical parts with external ribs, and particularly relates to an auxiliary demoulding component suitable for cylindrical parts with external ribs and a mold integrated demoulding device. Background Art

[0002] During the demoulding process of cylindrical parts, it is often difficult to remove them from the mold. This is mainly due to the structural characteristics of the cylindrical parts and the complexity of the demoulding process. For example, for cylindrical parts with a long length or a small angle, the demoulding stroke is long, and the friction between the mold and the mold is large, making the demoulding process extremely difficult. In addition, unreasonable mold design is also one of the important reasons for the difficulty in demoulding. For example, insufficient demoulding slope, insufficient mold surface finish, poor exhaust and other problems will increase demoulding resistance.

[0003] In the demoulding method of cylindrical parts with external ribs, the lower mold is divided into two parts at the external ribs of the cylindrical parts. When demoulding, the upper part needs to be removed first, and when removing the upper part of the lower mold, manual demoulding is usually adopted. This method is labor-intensive, inefficient, and difficult to deal with cylindrical parts with complex structures. In addition, the lower mold needs to be re-spliced ​​before the next use. The manual demoulding method can easily lead to the upper and lower parts not being completely aligned during splicing, resulting in errors in the next molding process of the cylindrical parts, and more serious safety accidents.

[0004] In summary, in order to solve the problems of high strength, low efficiency and secondary alignment of cylindrical parts with external ribs during manual demoulding, the present invention provides an auxiliary demoulding device suitable for cylindrical parts with external ribs.

As an illustration, the cylindrical part 100 may generally include external ribs and internal ribs. In the traditional process, the external ribs of the cylindrical part 100 are first formed, and then the internal ribs of the cylindrical part 100 are formed. The external ribs of the cylindrical part 100 with external ribs described in the embodiment of the present invention have been formed in the previous process, and do not involve the forming of the external ribs of the cylindrical part 100.

Through the above arrangement, the lifting frame in the present invention can move the upper half (for example, the lower mold 9) of the lower mold 9 when the cylindrical part 100 is demolded. Figure 3 The support portion 95 of the lower mold is lifted, so that the upper half of the cylindrical member 100 is exposed to the lower mold to continue demoulding, which is more efficient; after the demoulding of the cylindrical member 100 is completed, the lifting frame can lift the upper half of the lower mold (for example Figure 3 The abutment portion 95) is re-engaged with the lower half of the lower mold (eg Figure 3 Compared with the manual secondary alignment method, the moving trajectory of the lifting frame is a straight line, which can make the alignment between the upper part of the lower mold 9 and the lower part of the lower mold 9 more accurate, effectively reducing the safety hazards caused by the misalignment of the secondary alignment, and improving the safety of the cylindrical part 100 during the next molding.

When the lifting rod 2 rotates, the adapter block 3 can move along the axial direction of the lifting rod 2.

[0051] In the auxiliary demoulding assembly for a cylindrical member with an outer rib provided in an embodiment of the present invention, refer to Figure 2, the lifting frame further includes a support rod 5, and the support rod 5 is arranged on the lifting frame base 1; a second through hole (not shown in the figure) is further provided in the adapter block 3, and the support rod 5 passes through the second through hole and is slidably connected to the adapter block 3. In a specific embodiment, refer to Figure 2 , the number of the support rods 5 is two, two second through holes are provided in the adapter block 3, and the two support rods 5 respectively correspond to the two second through holes; the two support rods 5 are respectively located on both sides of the lifting rod 2.

[0052] In the embodiment of the present invention, in the auxiliary demolding assembly applicable to the outer rib cylindrical part, refer to Figure 1 , the lower mold 9 and the cylindrical part 100 can be referred to Figure 3 , the pushing member 4 includes an extension rod 41 and a pushing block 42. One end of the extension rod 41 is connected to the adapter block 3, and the other end extends in a direction away from the adapter block 3; the pushing block 42 is arranged at the end of the extension rod 41 away from the adapter block 3. In a specific embodiment, the lifting rod 2 is parallel to the side wall of the cylindrical part 100, and the extension rod 41 is arranged perpendicular to the lifting rod 2. In another specific embodiment, a buffer pad 43 is provided on the top of the pushing block 42, and the buffer pad 43 can effectively buffer the pressure when the pushing block 42 contacts the upper half of the lower mold 9, so that the upper half of the lower mold 9 can be smoothly separated from the lower half of the lower mold 9. In another specific embodiment, a reinforcing rib 7 is further provided between the extension rod 41 and the adapter block 3, and the reinforcing rib 7 can strengthen the connection relationship between the extension rod 41 and the adapter block 3 and enhance the compressive resistance of the extension rod 41 when pushing the upper half of the lower mold 9. In a specific embodiment, the number of the lifting frames is four, and the four lifting frames are arranged around the lower mold 9, and the included angles between adjacent two lifting frames and the lower mold 9 are the same. As an illustration, the shape of the cylindrical part 100 is usually a cylinder, and the shape of the lower mold 9 is usually matched with that of the cylindrical part 100 and is also a cylinder.

The bottom of the disassembly portion 93 is provided with a disassembly portion groove 93.1, and the top of the fixed portion 94 is provided with a fixed portion groove 94.1; when the disassembly portion 93 and the fixed portion 94 are spliced, the disassembly portion groove 93.1 and the fixed portion groove 94.1 form an outer rib groove 92, wherein the outer rib groove 92 of the lower mold 9 usually has a cut that completely cuts off the lower mold 9, and the cut divides the lower mold 9 into a disassembly portion 93 and a fixed portion 94, the fixed portion 94 is used to load the lower half of the cylindrical member 100, and the disassembly portion 93 is used to load the upper half of the cylindrical member 100, and the two cut surfaces on the disassembly portion 93 and the fixed portion 94 are uneven cut surfaces, and the uneven cut surfaces are The friction force is greater than that of a flat cross-section, so when the disassembly portion 93 and the fixing portion 94 are spliced ​​together, it is more stable and not prone to radial displacement; the disassembly portion 93 is also provided with a supporting portion 95 on the outer wall, and the pushing member 4 is located below the supporting portion 95. The supporting portion 95 is usually integrally formed with the disassembly portion 93. When the cylindrical member 100 is demolded, the pushing member 4 moves upward with the adapter block 3. The pushing member 4 should first contact the lower surface of the supporting portion 95, and then lift the supporting portion 95 upward to separate the supporting portion 95 from the fixing portion 94.
