Description

Technical Field

[0001] This utility model relates to the technical field of inserts for bonding different products, and in particular to an insert for rotating and switching between different products. Background Technology

[0002] The plastic door and window industry has developed rapidly, with diverse styles and varieties, resulting in an increasing number of profiles required for assembly. Among the ever-evolving plastic door and window profiles, the injection molding process mostly involves heating the material through an extruder, then pressing it through an extrusion die to form a preform. The preform undergoes dry setting, wet setting, rapid cooling, and curing to form a finished product.

[0003] In the current injection molding process for plastic doors and windows, each type of profile requires a separate mold, which increases costs. As the number of molds increases, companies need to invest more capital in storing and maintaining them, increasing operating costs and management complexity. Furthermore, the design and manufacture of each mold requires specialized technicians, further increasing technical complexity and management difficulty.

[0004] The existing plastic door and window injection molding process requires a set of molds for each profile, which increases costs. By replacing conventional inserts with rotatable inserts and designing water and air channels, the rotated assembly can be adapted to different product shapes, thus achieving the effects of simple design, simple structure and low cost. It also enables the mold to produce two profiles in one mold during the molding process, reducing costs and saving resources.

[0005] However, during the use of the device, the injection molding of the mold will cause the rotating insert to rotate and shift under the action of force. The rotational shift of the insert may cause the dimensions of the injection molded product to exceed the tolerance range, thereby affecting the assembly and performance of the product. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rotating switching insert for different products, which solves the problem of increased costs caused by the need for a set of molds for the production of each profile.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A rotating insert for adapting to different products includes a bottom mold and a profile body. The bottom mold contains an irregularly shaped rotating insert. One corner of the rotating insert has a first fitting groove, and another corner of the rotating insert, obliquely symmetrical to the first fitting groove, has a second fitting groove. The first and second fitting grooves are used to fit different profile bodies. This allows the rotating insert to adapt to two different profile bodies in a single mold during the switching molding process.

[0009] As a further improvement of this utility model, sliding frames are symmetrically fixedly connected to the upper and lower ends of the irregularly shaped rotating insert, and rotating blocks are symmetrically fixedly connected to the center of both sides of the irregularly shaped rotating insert near the inner wall of the bottom mold. Thus, the sliding frames and rotating blocks prevent the irregularly shaped rotating insert from moving.

[0010] As a further improvement of this utility model, the top of the bottom mold is attached to the top of the top mold, and two placement frames are symmetrically fixedly connected to one side of the bottom mold. A fixing pin is slidably connected to the top of the placement frame near the bottom mold. This allows the fixing pin to be placed and fixed in place.

[0011] As a further improvement of this utility model, two abutment plates are symmetrically fixedly connected to the top of the bottom mold. Each abutment plate has a fitting groove on its bottom side near the placement frame. Two circular grooves are symmetrically formed inside the bottom mold. This allows the user to easily secure the fixing pin.

[0012] As a further improvement of this utility model, the irregularly shaped rotating inserts are all disposed inside the circular grooves. The bottom mold has symmetrically formed rotating grooves on both sides of the circular grooves. The rotating blocks are rotatably connected inside the rotating grooves. The bottom mold has mold grooves on the adjacent sides of the circular grooves. The bottom end of the top mold has symmetrically formed mold protrusions. This facilitates the rotation of the irregularly shaped rotating inserts.

[0013] As a further improvement of this utility model, the fixing pin can be pulled out from the placement frame and slidably connected to the sliding frame, and the fixing pin fits perfectly into the fitting groove. This allows the fixing pin to effectively secure the irregularly shaped rotating insert.

[0014] Compared with the prior art, the advantages of this utility model are as follows:

[0015] 1. The process involves a rotating slot, a shaped rotating insert, two fitting slots, and a rotating block. The operator controls the shaped rotating insert to rotate the rotating block along the inside of the rotating slot, allowing either fitting slot one or fitting slot two to fit with the profile body. This enables the shaped rotating insert to adapt to different product shapes. A well-designed shaped rotating insert can reduce mold material usage while maintaining mold functionality, thus lowering costs. The shaped rotating insert can be customized to suit different product shapes and requirements, allowing the mold to adapt to a wider variety of products. This flexibility is particularly important for multi-variety, small-batch production. Furthermore, by rotating and changing the position of the shaped rotating insert with different slot shapes, the mold can flexibly adapt to the production needs of different products without redesigning and manufacturing the entire mold. This greatly improves the mold's versatility and flexibility, making production line changes and adjustments faster and more convenient.

[0016] 2. By using a fixed pin and a sliding frame, the operator can control the removal of the fixed pin from the placement frame, and then pass the fixed pin through the sliding frame fixedly connected to the top of the irregular rotating insert. The fixed pin passing through the sliding frame engages with the fitting groove opened in the abutment plate, thereby achieving the effect of fixing and limiting the irregular rotating insert. Fixing the rotatable irregular rotating insert can reduce mold adjustment time because the irregular rotating insert remains stable during injection molding, eliminating the need for frequent adjustments to its position or angle. Moreover, the fixed irregular rotating insert facilitates the automation of the injection molding process, reducing manual intervention and significantly improving production efficiency. Due to the stability of the irregular rotating insert, it is less prone to displacement or deformation during injection molding, thus reducing the scrap rate caused by problems with the irregular rotating insert. The fixed irregular rotating insert also makes the injection molding process more controllable, facilitating real-time monitoring and adjustment of product quality. Attached Figure Description

Detailed Implementation

[0023] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0025] As shown in the figure, a rotating insert for bonding different products includes a circular groove 107, a rotating groove 108, an irregularly shaped rotating insert 201, a bonding groove one 202, a bonding groove two 203, and a rotating block 205.

[0026] Firstly, when the user needs to injection mold the profile body 300 that conforms to the fitting groove 202, the user pulls out the fixing pin 104 that is slidably connected to the placement frame 103 fixedly connected to the side of the bottom mold 101, and then pushes the fixing pin 104 in along the sliding frame 204. When the fixing pin 104 engages with the fitting groove 106 opened in the abutment plate 105 fixedly connected to the top of the bottom mold 101, the fixed pin 104 will fix the irregular rotating insert 201. Fixing the irregular rotating insert 201 can reduce subsequent processing steps, such as trimming and polishing, because the injection molded product is close to the final shape. Moreover, due to the stable fixation of the irregular rotating insert 201, it is not easy for it to shift or deform during the injection molding process, thus reducing the scrap rate caused by problems with the irregular rotating insert 201.

[0027] Furthermore, when it is necessary to mold a profile body 300 that fits into the fitting groove 203, the user pulls out the fixing pin 104 that fits into the sliding frame 204 and the fitting groove 106, and reinserts it into the placement frame 103. Then, the user controls the irregular rotating insert 201 to rotate. Since the rotating block 205 fixedly connected to the side of the irregular rotating insert 201 is rotatably connected to the rotating groove 108 opened on the side of the circular groove 107, the irregular rotating insert 201 will rotate. When the fitting groove 203 rotates to the original fitting groove 202 position, the fixing pin 104 is pulled out to lock the irregular rotating insert 201. This allows the irregular rotating insert 201 to adapt to different product shapes. With the reasonable design of the irregular rotating insert 201, the amount of mold material used can be reduced while ensuring the mold function, thereby reducing costs. The design of the irregular rotating insert 201 can be customized according to the shape and requirements of different products, so that the mold can be adapted to more types of products.

[0028] The advantages of this invention are as follows: 1) Fixing the rotatable irregular-shaped rotating insert 201 reduces mold adjustment time because the insert remains stable during injection molding, eliminating the need for frequent adjustments to its position or angle. 2) The irregular-shaped rotating insert 201 can be fixed during injection molding, facilitating automation of the injection molding process, reducing manual intervention, and significantly improving production efficiency. 3) The fixed irregular-shaped rotating insert 201 ensures its accurate position in the mold, guaranteeing the dimensional accuracy and appearance quality of the injection-molded product. Furthermore, due to the stability of the irregular-shaped rotating insert 201, it is less prone to displacement or deformation during injection molding, thus reducing the scrap rate caused by insert issues. 4) Through the design of the water and air channels, the rotated irregular-shaped rotating insert 201 can adapt to different product shapes, achieving a simple design, simple structure, and low cost.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
