Description

Technical Field

[0001] The utility model relates to the field of molds, in particular to a mold for optimizing and reducing water inlet material. Background Art

[0002] When using molds to process products, the molten raw materials cool and solidify in the mold cavity, and the materials in the mold flow channel will also be formed and solidified. Therefore, there is sprue material left on the demolded product. In order to put the product on the market, the sprue material needs to be removed and polished.

[0003] Since the flow channel on the mold has a fixed length, when a large number of products are processed, multiple products have sprue materials of equal length. When the product is polished, the sprue material is removed or even abandoned, resulting in a waste of resources. In order to reduce the waste of resources, various molds for reducing sprue materials have appeared on the market. For example, a Chinese patent with patent publication number CN219028355U discloses a sprue removal device, which includes a base, a mold core positioning member arranged on the base, and a sprue removal assembly. The mold core positioning member is used to position the mold core with sprue material. The sprue removal assembly includes a push plate and a driving assembly connected to the push plate and driving the push plate to move. The shape of the push plate is semi-I-shaped. The sprue removal device in the utility model has a higher sprue removal efficiency through the arrangement of the semi-I-shaped push plate, thereby improving the processing efficiency of pen products.

[0004] The device provided by the above patent, as well as other sprue material removal devices, can remove sprue material from products, but it also means that in order to remove sprue material from a large number of products, it is necessary to equip multiple sets of devices with this function, which increases the manufacturing cost of the product and increases the processing steps of the product.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The following is a further description with reference to the accompanying drawings and specific embodiments: Example

[0027] like Figure 1 As shown, a mold for optimizing and reducing sprue includes a first mold body 1 and a second mold body 2. A mold groove is provided on the side walls of the first mold body 1 and the second mold body 2 that are close to each other, so that a complete injection cavity can be formed when the first mold body 1 and the second mold body 2 are fitted together. In addition, a flow channel is provided on the first mold body 1, and the flow channel is communicated with the injection cavity. Therefore, the molten raw material can enter the injection space from the flow channel, and the raw material can be molded after being cooled.

[0028] like Figure 2 , Figure 3 , Figure 4As shown, in order to avoid the presence of long lengths of sprue material on the manufactured products, the first mold body 1 is provided with two flow channels, namely the first flow channel 11 and the second flow channel 14. The centers of the first flow channel 11 and the second flow channel 14 are located on the same straight line, and the first flow channel 11 is located on the side of the second flow channel 14 away from the second mold body 2. Specifically, the diameter of the first flow channel 11 is larger than the diameter of the second flow channel 14, and the contact ends of the first flow channel 11 and the second flow channel 14 are set to a curved surface structure, and a blocking ball 41 is arranged at the curved surface structure. The blocking ball 41 is in sealing contact with the curved surface end, and a material hole 43 is arranged through the blocking ball 41. The material hole 43 can be connected and opposite to the second flow channel 14, and the diameter is less than or equal to the diameter of the second flow channel 14. Therefore, when the blocking ball 41 is stably placed and the material hole 43 is connected to the first flow channel 11 and the second flow channel 14, the raw material can move from the first flow channel 11 to the second flow channel 14 and flow into the injection molding cavity. When the blocking ball 41 is rotated ninety degrees, the material hole 43 and the first flow channel 11 and the second flow channel 14 are in a mutually perpendicular relationship. At this time, the channel for the flow of raw materials is cut off, and the connection between the product and the raw material is cut off at the same time, which can effectively avoid the formation of a longer sprue material on the product. During the mold processing, the length of the second flow channel 14 can be reduced according to the requirements, and the length of the second flow channel 14 can even be set to zero. The first flow channel 11 and the second flow channel 14 form a flow channel group.

[0029] like Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, in order to control the rotation of the blocking ball 41, a through hole 15 is provided on the first mold body 1, and the lower end of the through hole 15 is communicated with the flow channel group. A rotating shaft 4 is provided through the through hole 15, and a connecting seat 46 is provided at the upper end through a bearing. The connecting seat 46 is installed on the first mold body 1, and a motor 44 is provided on the top of the rotating shaft 4, and the motor 44 is also connected to the first mold body 1. A polygonal groove 45 is provided on the lower end face of the rotating shaft 4, and a polygonal column 42 is provided on the top of the blocking ball 41, and the polygonal column 42 is inserted into the polygonal groove 45. With the cooperation of the polygonal column 42 and the polygonal groove 45, the rotating shaft 4 is stably connected to the blocking ball 41. Therefore, the rotation of the rotating shaft 4 can be controlled by the rotation of the motor 44 to drive the blocking ball 41 to rotate, adjust the direction of the material hole 43, and then control the smoothness of the flow channel group. In order to limit the position of the blocking ball 41, a limiting plate 13 is provided on the inner side of the first flow channel 11, and the end face of the limiting plate 13 is set as an arc structure, and is in sliding contact with the blocking ball 41. Example

[0030] like Figure 1As shown, a mold for optimizing and reducing sprue includes a first mold body 1 and a second mold body 2. A mold groove is provided on the side walls of the first mold body 1 and the second mold body 2 that are close to each other, so that a complete injection cavity can be formed when the first mold body 1 and the second mold body 2 are fitted together. In addition, a flow channel is provided on the first mold body 1, and the flow channel is communicated with the injection cavity. Therefore, the molten raw material can enter the injection space from the flow channel, and the raw material can be molded after being cooled.

[0031] like Figure 2 , Figure 3 , Figure 4 As shown, in order to avoid the presence of long lengths of sprue material on the manufactured products, the first mold body 1 is provided with two flow channels, namely the first flow channel 11 and the second flow channel 14. The centers of the first flow channel 11 and the second flow channel 14 are located on the same straight line, and the first flow channel 11 is located on the side of the second flow channel 14 away from the second mold body 2. Specifically, the diameter of the first flow channel 11 is larger than the diameter of the second flow channel 14, and the contact ends of the first flow channel 11 and the second flow channel 14 are set to a curved surface structure, and a blocking ball 41 is arranged at the curved surface structure. The blocking ball 41 is in sealing contact with the curved surface end, and a material hole 43 is arranged through the blocking ball 41. The material hole 43 can be connected and opposite to the second flow channel 14, and the diameter is less than or equal to the diameter of the second flow channel 14. Therefore, when the blocking ball 41 is stably placed and the material hole 43 is connected to the first flow channel 11 and the second flow channel 14, the raw material can move from the first flow channel 11 to the second flow channel 14 and flow into the injection molding cavity. When the blocking ball 41 is rotated ninety degrees, the material hole 43 and the first flow channel 11 and the second flow channel 14 are in a mutually perpendicular relationship. At this time, the channel for the flow of raw materials is cut off, and the connection between the product and the raw material is cut off at the same time, which can effectively avoid the formation of a longer sprue material on the product. During the mold processing, the length of the second flow channel 14 can be reduced according to the requirements, and the length of the second flow channel 14 can even be set to zero. The first flow channel 11 and the second flow channel 14 form a flow channel group.

[0032] like Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, in order to control the rotation of the blocking ball 41, a through hole 15 is provided on the first mold body 1, and the lower end of the through hole 15 is communicated with the flow channel group. A rotating shaft 4 is provided through the through hole 15, and a connecting seat 46 is provided at the upper end through a bearing. The connecting seat 46 is installed on the first mold body 1, and a motor 44 is provided on the top of the rotating shaft 4, and the motor 44 is also connected to the first mold body 1. A polygonal groove 45 is provided on the lower end face of the rotating shaft 4, and a polygonal column 42 is provided on the top of the blocking ball 41, and the polygonal column 42 is inserted into the polygonal groove 45. With the cooperation of the polygonal column 42 and the polygonal groove 45, the rotating shaft 4 is stably connected to the blocking ball 41. Therefore, the rotation of the rotating shaft 4 can be controlled by the rotation of the motor 44 to drive the blocking ball 41 to rotate, adjust the direction of the material hole 43, and then control the smoothness of the flow channel group. In order to limit the position of the blocking ball 41, a limiting plate 13 is provided on the inner side of the first flow channel 11, and the end face of the limiting plate 13 is set as an arc structure, and is in sliding contact with the blocking ball 41.

[0033] like Figure 2 , Figure 3 , Figure 7 As shown, in order to prevent the raw material in the first flow channel 11 from cooling and solidifying, an annular groove 12 is provided on the side wall of the first mold body 1 away from the second mold body 2. The first flow channel 11 is located on the inner side of the annular groove 12, and its length is less than or equal to the length of the annular groove 12. A heating mechanism 5 is provided at the annular groove 12. The heating mechanism 5 includes an end plate 52 and a plurality of heating rods 51. The plurality of heating rods 51 are evenly distributed and arranged on the side of the end plate 52. A wire is provided at the end plate 52. When the wire is connected to an external power source, the heating rod 51 can be powered on and heated. The end plate 52 is threadedly connected and arranged at the annular groove 12, and a slot 53 is provided on the end surface. The heating rod 51 is also arranged at the annular groove 12. Under the action of the heating rod 51, the temperature in the first flow channel 11 can be higher than the temperature in the injection cavity, so that when the raw material in the injection cavity is cooled, the raw material in the first flow channel 11 is in a molten state, providing support for the rotation of the blocking ball 41. The rotating shaft 4, the blocking ball 41 and the heating mechanism 5 constitute a material limiting component 3.
