Description

Technical Field

[0001] This utility model relates to the field of injection mold processing and production technology, and in particular to a simplified sprue plate structure. Background Technology

[0002] In existing technology, the common opening action of a three-plate injection mold structure generally involves the injection molding machine opening the mold. The first action opens the sprue plate and sprue plate because the nylon clamping device holds the A and B plates together. The sprue hook then disengages the sprue from the product. Next, due to the limiting action of the bolt tie rod, the second action opens the front panel and sprue plate, allowing the sprue plate to disengage from the sprue bushing. Finally, the stop screw stops the entire front mold section, and the nylon clamping device between the A and B plates opens further, allowing the A and B plates to fully open and the product to be removed from the mold, completing the opening action of the three-plate mold. However, because the sprue plate in this type of three-plate mold structure is thicker, the overall thickness of the mold increases. Correspondingly, the tonnage of the machine used for mold production also needs to be increased, and the price of the three-plate mold blank is higher than that of a two-plate mold, thus affecting the overall price of the mold.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a simplified sprue plate structure.

[0005] The technical solution of this utility model is as follows: A simplified sprue plate structure is provided, including: a panel, an A plate, and a B plate arranged in sequence. A sprue plate is provided between the panel and the A plate. The A plate is provided with a placement groove corresponding to the sprue plate. The sprue plate is embedded in the placement groove. A plug screw is provided on the side of the panel facing the A plate. The A plate is provided with a first through hole corresponding to the plug screw. The end of the plug screw moves in the first through hole. The plug screw passes through the sprue plate and is locked onto the panel.

[0006] Furthermore, a sprue sleeve is provided on the panel, and the sprue formed by the sprue sleeve during injection molding is attached to the sprue plate.

[0007] Furthermore, a bolt rod is provided on the side of the panel facing plate A, a second through hole is provided on plate B corresponding to the bolt rod, and a stepped hole is provided on plate A corresponding to the bolt rod. The end of the bolt rod moves in the second through hole, and the bolt rod passes through the stepped hole and is locked onto the panel.

[0008] Furthermore, a nylon mold clamp is provided between plate B and plate A, and the nylon mold clamp is fixed to plate B.

[0009] By adopting the above solution, this utility model uses an embedded sprue plate setting method, embedding the sprue plate into the placement groove on the A plate, thereby reducing the overall thickness of the mold and facilitating mold processing and manufacturing. Simultaneously, it facilitates the production of mold blanks using the mold blank model of the two-plate mold, reducing the overall cost of the mold blank. Attached Figure Description

[0011] Figure 2 This is a schematic diagram of the structure with the panel and A-plate in the open state. Detailed Implementation

[0012] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0013] Please see Figure 1 , Figure 2 This utility model provides a simplified sprue plate structure, including: a panel 1, an A plate 2, and a B plate 3 arranged sequentially. A sprue plate 4 is disposed between the panel 1 and the A plate 2. The A plate 2 has a placement groove 21 corresponding to the sprue plate 4, and the sprue plate 4 is embedded in the placement groove 21. A stop screw 11 is disposed on the side of the panel 1 facing the A plate 2. The A plate 2 has a first through hole 22 corresponding to the stop screw 11. The end of the stop screw 11 moves in the first through hole 22, and the stop screw 11 passes through the sprue plate 4 and is locked onto the panel 1. During mold opening, when the panel 1 and the A plate 2 are opened, the sprue will detach. Furthermore, during the continued mold opening process, after the stop screw 11 contacts the sprue plate 4, the sprue plate 4 moves along with it under the action of the stop screw 11, causing the sprue to detach from the product. By adopting an embedded sprue plate 4, which is embedded in the placement groove 21 on plate A 2, the overall thickness of the mold is reduced, making it easier to process and manufacture. Simultaneously, it facilitates the production of mold blanks using the same mold blank model as the two-plate mold, thus reducing the overall cost of the mold blank.

[0014] In some embodiments, a sprue sleeve 13 is provided on the panel 1, and the sprue 14 formed by the sprue sleeve 13 during injection molding is attached to the sprue plate 4.

[0015] In some embodiments, a bolt rod 12 is provided on the side of the panel 1 facing the A plate 2, a second through hole 31 is provided on the B plate 3 corresponding to the bolt rod 12, and a stepped hole 23 is provided on the A plate 2 corresponding to the bolt rod 12. The end of the bolt rod 12 moves in the second through hole 31, and the bolt rod 12 passes through the stepped hole 23 and is locked onto the panel 1.

[0016] In some embodiments, a nylon mold clamp 5 is provided between the B plate 3 and the A plate 2, and the nylon mold clamp 5 is fixed on the B plate 3.

[0017] In the specific operation, during the master mold opening process, under the action of the nylon mold clamp 5, plates A2 and B3 first open panel 1 and plate A2, causing the sprue 14 to detach from the sprue bushing 13. During the continued mold opening process, since the stop screw 11 and bolt tie rod 12 are both fixed to panel 1, they move with panel 1. When the stop screw 11 contacts the sprue plate 4, the sprue plate 4 moves with panel 1 under the action of the stop screw 11, thereby causing the sprue 14 to detach from the product. This continues until the bolt tie rod 12 contacts and limits the step position in the stepped hole 23 of plate A2, at which point the sprue 14 automatically falls off, completing the mold opening action of the front mold section. Then, the mold opening action continues, opening the nylon mold clamp 5 between plate A2 and plate B3, allowing plate A2 and plate B3 to fully open, and the product to be removed from the mold, completing the entire mold opening process.

[0018] In summary, this utility model, by employing an embedded sprue plate design, embeds the sprue plate into the placement groove on plate A, thereby reducing the overall thickness of the mold and facilitating mold manufacturing. Simultaneously, it facilitates the production of mold blanks using the same mold blank model as the two-plate mold, reducing the overall cost of the mold blank.

[0019] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
