Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold technology, and in particular to an internal thread structure of a plastic product molding mold. Background Technology
[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, and stamping. In short, molds are tools used to make shaped objects. These tools are composed of various parts, and different molds are composed of different parts. They mainly achieve the processing of the shape of the object by changing the physical state of the material being molded.
[0003] However, existing devices suffer from poor stability and long production cycles, resulting in low production efficiency. Therefore, an internal thread structure for a plastic product molding die is provided to solve the problems mentioned in the background art. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides an internal thread structure for plastic product molding dies, aiming to improve the problems of poor stability and long production cycle in the prior art, which leads to low production efficiency.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an internal threaded structure for a plastic product molding die, comprising a base, a ball screw fixedly connected to the upper part of the base, a drive gear fixedly connected to the outer side of the ball screw, a main rotating core provided on the left and rear sides of the ball screw, an auxiliary helical component fixedly connected to the outer middle side of the main rotating core, a transmission gear fixedly installed on the lower side of the auxiliary helical component, and a product provided on the upper side of the main rotating core.
[0006] Furthermore, the transmission gear and the drive gear are meshed together for the rotation of the main rotating core.
[0007] Furthermore, the product is threaded onto the outside of the main rotating core for demolding.
[0008] Furthermore, a bearing is provided on the lower outer side of the main rotating core.
[0009] Furthermore, the ball screw is horizontally positioned, and the ball screw provides longitudinal displacement of the main rotating core by rotation to assist in the demolding process of the product.
[0010] Furthermore, the auxiliary spiral component is connected to the main rotating core via a keyway structure for fixing the main rotating core and the auxiliary spiral component.
[0011] This utility model has the following beneficial effects:
[0012] In this invention, the template drives the ball screw to rotate. At this time, the rotation of the ball screw drives the drive gear fixed on its outer side to rotate as well. The rotation of the drive gear further drives the transmission gear meshing with it to rotate, thereby realizing the transmission of power. This ensures the thread starting point, has good stability, and a lifespan of up to 100W molds.
[0013] In this invention, when mold opening is required, the main rotating core moves along its axial direction according to the thread P value of the auxiliary rotating device, gradually separating from the formed product, which shortens the production cycle and improves production efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides: an internal threaded structure for a plastic product molding die, including a base 8, a ball screw 7 fixedly connected to the upper part of the base 8, a drive gear 5 fixedly connected to the outer side of the ball screw 7, a main rotating core 2 provided on the left and rear sides of the ball screw 7, an auxiliary spiral component 3 fixedly connected to the outer middle side of the main rotating core 2, a transmission gear 4 fixedly installed on the lower side of the auxiliary spiral component 3, and a product 1 provided on the upper side of the main rotating core 2;
[0021] When mold opening is required, the template pulls the ball screw 7 to rotate through a specific mechanism. At this time, the rotation of the ball screw 7 drives the drive gear 5 fixed on its outer side to start rotating as well. The rotation of the drive gear 5 further drives the transmission gear 4 meshing with it to rotate, thereby realizing the transmission of power. According to the thread P value of the auxiliary rotation device, the main rotating core 2 moves along its axial direction and gradually separates from the formed product 1.
[0022] Reference Figure 1 , Figure 2 and Figure 3 The transmission gear 4 and the drive gear 5 are meshed and connected for the rotation of the main rotating core 2. The product 1 is threadedly connected to the outside of the main rotating core 2 for demolding. A bearing 6 is provided on the lower outer side of the main rotating core 2. The ball screw 7 is horizontally set and provides longitudinal displacement of the main rotating core 2 by rotation to assist the demolding process of the product 1. The auxiliary spiral component 3 is connected to the main rotating core 2 through a keyway structure for fixing the main rotating core 2 and the auxiliary spiral component 3.
[0023] The transmission gear 4 and the drive gear 5 mesh together, which can drive the transmission gear 4 to rotate, thereby realizing the transmission of power. According to the thread P value of the auxiliary rotating device, the main rotating core 2 moves along its axial direction. The product 1 is threaded on the outside of the main rotating core 2, which can easily remove the product 1 from the main rotating core 2 for easy replacement or maintenance. The main rotating core 2 is supported by the set bearing 6 to ensure the smoothness of the movement.
[0024] Working Principle: During the molding process, the entire system remains stationary. When mold opening is required, the template drives the ball screw 7 to rotate. At this time, the rotation of the ball screw 7 drives the drive gear 5 fixed on its outer side to rotate as well. The rotation of the drive gear 5 further drives the transmission gear 4 meshing with it to rotate, thereby realizing the transmission of power. According to the thread P value of the auxiliary rotating device, the main rotating core 2 moves along its axial direction and gradually separates from the molded product 1. During this process, the main rotating core 2 is supported by the set bearing 6 to ensure the smoothness of the movement. At the same time, the design of the auxiliary spiral component 3 optimizes the material transfer efficiency, provides convenience for the subsequent molding process, and improves the operability of the mold and the molding quality.
