[0048] Embodiment: Figure 1 It is a top view of a double-material wind deflector injection mold in the embodiment, Figure 2 It is Figure 1 It is a sectional view in B-B direction, as Figure 2 Indicated, a double-material wind deflector injection mold is composed of a first mold 1, a second mold 2 and a plurality of separation devices 3 between the first mold 1 and the second mold 2; specifically, as Figure 3 Indicated, four separation devices 3 are arranged on the second mold 2, and the outer side walls of the four separation devices 3 are sequentially and closely adhered to achieve a sealing effect, and the area formed by the four separation devices 3 in the center forms a cavity 21; Figure 4 It is Figure 2 It is an enlarged view of the A area, Figure 5 It isFigure 4 Enlarged view of the middle B region, as Figure 4 and Figure 5 The core 11 and the cavity 21 are combined to form the injection cavity 4.
[0049] As shown in Figure 4 and Figure 5 Each partition device 3 is provided with a first channel 32 communicating with the injection cavity 4, and a sliding partition 31 is arranged in the first channel 32, and the outer wall of the partition 31 is in close contact with the inner wall of the first channel 32 to form a seal. Each partition device 3 is provided with a driving assembly for driving the partition 31.
[0050] During injection molding, the first step is to push the corresponding partition 31 into the injection cavity 4 and abut against the core 11 through all the driving assemblies, and the outer wall of all the partitions 31 is in close contact with the outer wall of the core 11 to form a seal, and the outer wall of any two adjacent partitions 31 is in close contact to form a seal, and all the partitions 31 divide the injection cavity 4 into first and second cavities 41 and 42 that are not connected to each other; the second step is to complete the injection molding of the second cavity 42 part through the second injection port on the second mold 2 communicating with the second cavity 42, and wait for the second cavity 42 part to be formed; the third step is that all the driving assemblies drive the partitions 31 to exit the injection cavity 4, and each partition 31 is embedded in the corresponding first channel 32, and the end face of each partition 31 facing the injection cavity 4 is spliced with the end face of the corresponding partition device 3 facing the injection cavity 4 to form the inner wall of the injection cavity 4; the fourth step is to complete the injection molding of the part of the injection cavity 4 except the second cavity 42 through the first injection port on the first mold 1 communicating with the first cavity 41; the fifth step is to wait for the material to be formed and then demolded to complete the injection molding process.
[0051] Based on the above technical solution, four partition devices 3 are arranged to surround the cavity 21, a driving assembly is arranged in each partition device 3 to drive the telescopic partition 31, and the four partitions 31 are arranged around the injection cavity 4, which solves the problem that the traditional single partition cannot be simply adapted to the annular irregular injection cavity, avoids the damage to the core structure when the traditional single partition faces the annular irregular injection cavity, and avoids the problem that the traditional single partition needs additional structure to fill the partition exit space.
[0052] In order to ensure the sealing performance of the mold after the multiple partitions 31 replace the single partition, as shown in Figure 3 the outer side walls of the four partition devices 3 are sealed by the close contact between the surfaces, which ensures the sealing performance of the cavity 21, as shown in Figure 6 and Figure 7As shown, the outer walls of any two adjacent separators 31 abut each other at the abutment, and each separator 31 is provided with a planar structure 314 at the abutment. During the process of driving the separators 31 into the injection cavity 4 by the driving assembly, the planar structures 314 on any two adjacent separators 31 gradually approach and abut each other when the separators 31 abut the core 11. The outer wall shape of the abutment part of the core 11 and any separator 31 is engaged with the outer wall shape of the corresponding separator 31.
[0053] Thus, the sealing performance of the injection cavity 4 and the separators 31 when separating the injection cavity 4 is ensured by the cooperation between the surfaces, i.e. the sealing cooperation of the adjacent separators 31 is achieved by the close contact of the outer side walls of the adjacent separators 3 and the planar structures 314, and the end face of the abutment part of the separator 31 and the end face shape of the core 11 are engaged, which ensures the sealing effect after the cooperation of the four separators 31 and the separator 31 and the core 11, thereby ensuring the accuracy of the injection process. Compared with the traditional single separator, the cooperation of the four separators 31 for separating the injection cavity 4 can better cope with the annular injection cavity 4.
[0054] In the process of using the traditional single separator, the driving device directly drives the single separator to abut the core. Due to the straight-in and straight-out travel mode of the driving device, it is inevitable that the single separator collides with the core. The impact generated by the collision can easily damage the surface structure of the core, affecting the service life of the mold.
[0055] In order to solve the problem of easy collision between the separator and the core, the embodiments of the present application provide a smooth and accurate driving mode. Specifically, as shown in Figure 4 and Figure 5As shown, the driving device comprises a first oil cylinder 36, a first driving block 34 and a second driving block 35, each partition device 3 comprises a first shell 37 and a second shell 38, the second shell 38 is fixed on the second mold 2, and the first shell 37 is fixed on the end of the second shell 38 away from the second mold 2; the first oil cylinder 36 is fixed on the first shell 37, the first driving block 34 and the second driving block 35 are installed between the first shell 37 and the second shell 38, and the first channel 32 for installing the partition 31 is formed between the first shell 37 and the second shell 38; the driving direction of the driving end of the first oil cylinder 36 is from the first shell 37 to the second shell 38 and perpendicular to the end face of the second mold 2, one end of the first driving block 34 is connected with the driving end of the first oil cylinder 36, the other end of the first driving block 34 is in inclined sliding fit with one end of the second driving block 35, and the other end of the second driving block 35 is connected with one end of the partition 31 away from the injection cavity 4; a first inclined surface is arranged on the end of the second driving block 35 connected with the first driving block 34 and inclined outward relative to the injection cavity 4 and towards the first oil cylinder 36, a second inclined surface is arranged on the end of the first driving block 34 connected with the second driving block 35 and inclined in the same direction as the first inclined surface, a sliding groove 351 is arranged on the first inclined surface and extends in the inclined direction, and a sliding block 341 adapted to be embedded in the sliding groove 351 and in sliding fit is arranged on the second inclined surface.
[0056] When it is needed to partition the injection cavity 4, the driving end of the first oil cylinder 36 pushes the first driving block 34 to be close to the second shell 38, through the cooperation of the first inclined surface and the second inclined surface and the sliding block 341 and the sliding groove 351, the first driving block 34 pushes the second driving block 35 to be close to the injection cavity 4, so as to push the partition 31 into the injection cavity 4; when it is needed to make the partition 31 exit the injection cavity 4, the driving end of the first oil cylinder 36 pulls the first driving block 34 to be close to the first shell 37, through the cooperation of the first inclined surface and the second inclined surface and the sliding block 341 and the sliding groove 351, the first driving block 34 pulls the second driving block 35 to be away from the injection cavity 4, so as to pull the partition 31 to exit the injection cavity 4.
[0057] Thus, through the inclined surface sliding fit between the first driving block 34 and the second driving block 35, the vertical movement of the first oil cylinder 36 is converted into the horizontal movement of the second driving block 35 and the partition 31, the stable and accurate extension and contraction control of the partition 31 is realized, and compared with the mode that the traditional driving device directly drives the partition to abut against the core, the risk of damaging the core 11 is reduced.
[0058] In order to further solve the problem of collision between the partition 31 and the core 11, as shown in the drawings, Figure 3 , Figure 4 and Figure 6As shown in the exploded view of the middle partition device, a plurality of limiting columns 33 are arranged in the first channel 32, the limiting columns 33 are all fixed on the second shell 38, the limiting columns 33 all extend along the direction of the second shell 38 pointing to the first shell 37, and the first shell 37 is provided with grooves suitable for the end of the limiting column 33 to be embedded; each sheet body 312 is provided with a plurality of first grooves 311, each first groove 311 is correspondingly sleeved on a limiting column 33, and the outer wall of the limiting column 33 is tightly attached to the inner wall of the first groove 311; when the partition piece 31 enters the injection cavity 4 and abuts against the core 11, the limiting column 33 abuts at the end of the first groove 311 away from the injection cavity 4, and when the partition piece 31 exits the injection cavity 4, the limiting column 33 abuts at the end of the first groove 311 close to the injection cavity 4, and the maximum displacement distance of the limiting column 33 in the first groove 311 is the same as the thickness of the injection cavity 4 at the opening of the first channel 32.
[0059] Therefore, compared with the traditional driving device directly driving the partition piece, the limiting column 33 in the first channel 32 is arranged in sliding cooperation with the first groove 311 on the partition piece 31, which prevents the partition piece 31 from excessively extending or retreating, further improves the accuracy of the movement of the partition piece 31, reduces the risk of damage to the core 11, and improves the operation safety and the injection molding precision.
[0060] Since the traditional single partition piece forms a seal by cooperating with the core through an entire end surface, when facing a complex core surface, corresponding structures need to be processed on the surface of the single partition piece, which leads to low fault tolerance of the surface processing of the single partition piece, and the entire single partition piece needs to be replaced when part of the surface is damaged, resulting in high production cost.
[0061] In order to solve the problem of high replacement cost of the single partition piece, specifically, as shown in Figure 6 each partition device 3 is provided with two groups of driving assemblies, as shown in Figure 7 As shown in the top view of all partition pieces 31 and second driving blocks 35 in the partitioned injection cavity 4, each partition piece 31 is composed of at least two sheet bodies 312, Figure 7 As shown in the top view of all partition pieces 31 and second driving blocks 35 in the partitioned injection cavity 4, each partition piece 31 is composed of at least two sheet bodies 312, Figure 7 As shown in the top view of all partition pieces 31 and second driving blocks 35 in the partitioned injection cavity 4, each partition piece 31 is composed of at least two sheet bodies 312, Figure 7 As shown in the top view of all partition pieces 31 and second driving blocks 35 in the partitioned injection cavity 4, each partition piece 31 is composed of at least two sheet bodies 312, Figure 8As shown in the exploded view of the middle piece 312, the first driving block 34 and the second driving block 35, each piece 312 is stacked with a corresponding second driving block 35 at an end away from the injection cavity 4. Each second driving block 35 is provided with a plurality of guide posts 352 extending in the direction of the first shell 37 from the second shell 38 on the end surface connected with the piece 312. The piece 312 is provided with a first hole 313 corresponding to each guide post 352 and suitable for the guide post 352 to be embedded and fixed. Each piece 312 is installed on the corresponding second driving block 35 by aligning the first hole 313 on each piece 312 with the guide post 352 on the second driving block 35, and the piece 312 and the second driving block 35 are fixed by bolts. The outer wall shape of each piece 312 and the core 11 at the abutting position are mutually engaged to form a seal.
[0062] Compared with the traditional single partition, the partition 31 formed by the plurality of pieces 312 can be more flexibly replaced and adjusted, the flexibility and versatility of the mold are enhanced, maintenance and replacement are facilitated, long-term use costs are reduced, and compared with the traditional single partition in which the entire end surface is matched with the core, the matching of the plurality of pieces 312 with the core 11 can better cope with the core 11 of the annular structure.
[0063] As a more preferred scheme, all the pieces 312 are made of beryllium copper material, and the thickness of all the pieces 312 is 8.6 mm. The good thermal conductivity, wear resistance and toughness of beryllium copper enable the piece 312 to withstand high temperature and friction during the injection molding process, thereby prolonging the service life of the mold.
