[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1 to 7 The utility model provides a technical solution: a vertical conductive mold base, comprising:

[0029] The connecting plate 3 and the upper mold 1 at the bottom thereof, the upper mold 1 has a mold cavity, an assembly cavity 4 connected to the mold cavity is opened on the top of the upper mold 1, and an assembly cylinder 5 is rotatably assembled inside the assembly cavity 4; the bottom of the assembly cylinder 5 and the inner top of the mold cavity maintain the same plane or curved surface; the assembly cylinder 5 is provided with a plurality of conducting holes of different apertures, the conducting holes are connected to the mold cavity, and the plurality of conducting holes are distributed in a circular array.

[0030] In the prior art, products have different specifications, which is most directly reflected in the materials. Different plastics have different prices and qualities, and their temperature characteristics, viscosity and flow properties are also different. In the present invention, by designing multiple through holes with different apertures, the through holes can be quickly switched to meet faster sample production, and the assembly cylinder 5 and the assembly cavity 4 are designed to be in a vertical state, which can improve the flow properties of the molten material. Secondly, the through hole is directly connected to the mold cavity, reducing the flow time and path of the material.

[0031] In the present invention, the output position of the external pouring system is constant. When the assembly cylinder 5 is rotated, the conducting holes can be switched so that the pouring system can be connected to different conducting holes, thereby quickly switching conducting holes of different apertures.

[0032] Among them, the more preferred embodiment is that the assembly cylinder 5 is equipped with an assembly column 9, and the inner bottom of the assembly column 9 is provided with a plurality of assembly grooves 15, which are connected to the mold cavity. The interior of the assembly groove 15 is slidably installed with a sealing block 16, and the top of the assembly column 9 is also provided with a converging exhaust groove 8 connected to the assembly groove 15. When the sealing block 16 slides upward to a preset position, the converging exhaust groove 8 can be connected to the mold cavity through the assembly groove 15. The interior of the assembly groove 15 is provided with a driver that controls the up and down displacement of the sealing block 16. Please refer to Figure 7 During the pouring process, the air in the mold cavity may cause problems such as bubbles or depressions in the product. In this embodiment, an exhaust channel is formed between the mold cavity, the assembly groove 15 and the confluent exhaust groove 8. The air inside the mold cavity can enter the assembly groove 15 under the drive of the molten material and then be discharged through the confluent exhaust groove 8. Through the cooperation between the assembly groove 15 and the sealing block 16, the communication between the assembly groove 15 and the mold cavity can be controlled according to needs. A valve stem is also installed on the top of the sealing block 16, and the driver is a micro pneumatic telescopic cylinder. The valve stem is connected to the output end of the telescopic cylinder.

[0033] The combined exhaust groove 8 may be associated with an external negative pressure mechanism.

[0034] Furthermore, the bottom ends of the assembly groove 15 and the sealing block 16 are both designed to be inverted frustum-shaped. When the sealing block 16 is at the lowest point, the bottom of the sealing block 16 maintains the same plane or curved surface as the inner top of the mold cavity. In this embodiment, by designing the bottom of the assembly groove 15 and the sealing block 16 to be inverted frustum-shaped, the gradually increasing inner surface can reduce the entry of material, and the inverted frustum-shaped design can reduce the bottom area of ​​the sealing block 16, thereby reducing the size of the weld mark of the product. Secondly, when the exhaust groove 8 is combined with the negative pressure mechanism to work, the upward displacement of the sealing block 16 can adjust the efficiency of the exhaust.

[0035] The bottom of the sealing block 16 and the inner top of the mold cavity maintain the same plane or curved surface, which can effectively improve the production quality and appearance quality of the product.

[0036] Among them, a more preferred embodiment is that the top of the assembly cylinder 5 is fixedly equipped with a driven gear 12, and the top of the upper mold 1 is equipped with a rotatable driving gear, and the driving gear is meshed with the driven gear 12. When the assembly cylinder 5 needs to be rotated, the driving gear can be rotated so that the driven gear 12 and the assembly cylinder 5 can follow synchronously to adjust the switching conduction hole. The rotation of the driving gear can be controlled by a precision electronic control component such as a motor, and a graduation scale can also be designed on the top of the driven gear 12 for observation and adjustment.

[0037] The driven gear 12 is formed of a flange and a gear in one piece, and the flange is fixedly assembled with the assembly cylinder 5 .

[0038] In a more preferred embodiment, a threaded hole is provided on the top of the upper mold 1, a positioning hole is provided on the top of the connecting plate 3, and a hexagon socket bolt 13 is installed between the threaded hole and the positioning hole to lock the upper mold 1 and the connecting plate 3.

[0039] Furthermore, a parting mold 7 is installed on the inner bottom of the through hole. The parting mold 7 is composed of parting ribs and parting holes. The parting holes are distributed in a circumferential array. Figure 3 In this embodiment, by designing the parting mold 7, the flow path of the molten material in the through hole can be controlled, thereby ensuring that the molten material can flow and fill the mold cavity evenly, improving product quality. Secondly, the material can be separated and flowed out, reducing the occurrence of defects such as bubbles and cold flow lines. More importantly, the parting hole can change the connection between the through hole and the mold cavity from a vertical flow channel to several smaller and more inclined flow channels, making the connection between the product and the material in the through hole weaker, which is more conducive to product demolding.

[0040] Furthermore, the vertical conductive mold base also includes a lower mold 2, on which a plurality of guide pillars 11 are installed. The upper mold 1 and the connecting plate 3 are both designed with guide sleeves, and the guide pillars 11 are slidably assembled with the guide sleeves.

[0041] By utilizing the above structures, it is possible to switch between vias of different diameters, reduce bubbles in the mold cavity, and improve the molding quality of the product.

[0042] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and drawings can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
