Description

Technical Field

[0001] This utility model relates to precision manufacturing, and in particular to injection molding technology. Specifically, it relates to an upper-level double-sided injection molding die. Background Technology

[0002] See Figure 1 The screw 100 includes a main body post 101, on which a spiral part 102 is provided. In the current mold setting method, 50% of the mold groove is machined on the upper mold and the lower mold respectively. The two mold grooves are combined to form a forming mold cavity that matches the screw 100. However, in some cases, the size of the screw 100 is small, such as 2-3cm in diameter, 5-12cm in length, and 3-8cm in spiral part length. Machining 50% of the mold groove on the upper mold and the lower mold respectively is difficult.

[0003] Therefore, there is a need to provide an injection molding die with a top-level double-sided mold to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an injection molding die with a top-level double-sided mold.

[0005] This utility model achieves the above objectives through the following technical solution:

[0006] A double-sided injection molding die includes a lower mold, a lower mold groove setting plate, and a plurality of lower mold forming cavities on the lower mold groove setting plate. The lower mold forming cavities match the lower part of the main body column without the spiral part. The lower mold groove setting plate is correspondingly provided with an upper mold cavity assembly module. The upper mold cavity assembly module includes a set of upper mold cavity assembly blocks, each of which has an upper mold cavity A and an upper mold cavity B. The upper mold cavity A and the upper mold cavity B are combined to form an upper mold cavity that matches the remaining part of the main body column with the spiral part, thus forming a double-sided combined mold cavity injection molding structure.

[0007] Furthermore, the lower mold is provided with a positioning groove for the upper mold cavity assembly module.

[0008] Furthermore, a set of upper mold cavity assembly blocks is provided with a sprue channel, and the top of several upper mold cavities are connected to the sprue channel through a sprue gate.

[0009] Furthermore, after a set of upper mold cavity assembly blocks are combined, an upward-pushing pressure channel is formed in the middle.

[0010] Furthermore, an upward-pushing pressurizing component is provided inside the upward-pushing pressurizing channel.

[0011] Furthermore, the upward-push-filling pressure component is a push rod.

[0012] Furthermore, the number of forming cavities on both sides of the upward-pushing pressure channel is the same and is an even number.

[0013] Compared with the prior art, this utility model adopts an upper double-sided combined mold cavity injection molding structure. The lower mold cavity only needs to process a circular groove with few special elements, and the mold cavity with the spiral part is provided by a set of upper mold cavity combination blocks assembled at the top, which effectively reduces the difficulty of mold cavity setting.

[0019] Example:

[0020] See Figure 2-5 This embodiment demonstrates an upper-level double-sided injection molding die, including a lower mold 1, a lower mold groove setting plate 2, and a plurality of lower mold forming cavities 3 on the lower mold groove setting plate 2. The lower mold forming cavities 3 match the lower part of the main body column 101 without the spiral. The lower mold groove setting plate 2 is correspondingly provided with an upper mold cavity combination module 4. The upper mold cavity combination module 4 includes a set of upper mold cavity combination blocks 41, each of which has an upper mold cavity A42 and an upper mold cavity B43. The upper mold cavities A42 and B43 are combined to form an upper mold cavity that matches the remaining part of the main body column 101 with the spiral part, thus forming an upper-level double-sided combined mold cavity injection molding structure.

[0021] The lower mold 1 is provided with a positioning groove 11 for the upper mold cavity assembly module.

[0022] A set of upper mold cavity assembly blocks 4 is provided with a sprue channel 5, and the top of several upper mold cavities are connected to the sprue channel 5 through a sprue opening 6.

[0023] After a set of upper mold cavity assembly blocks 4 are assembled, an upward-pushing pressure channel 7 is formed in the middle.

[0024] An upward-pushing pressurizing component 8 is provided inside the upward-pushing pressurizing channel 7.

[0025] The push-type pressurizing component 8 is a push rod.

[0026] The number of forming cavities on both sides of the upper push-type pressure channel 7 is the same and is an even number.

[0027] Compared with the prior art, this utility model adopts an upper double-sided combined mold cavity injection molding structure. The lower mold cavity only needs to process a circular groove with few special elements, and the mold cavity with the spiral part is provided by a set of upper mold cavity combination blocks assembled at the top, which effectively reduces the difficulty of mold cavity setting.

[0028] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
