Description

Technical Field

[0001] The utility model relates to the technical field of automobile fastener production, in particular to an automobile fastener mould. Background Art

[0002] Injection molds play a vital role in the production process of automotive fasteners. These molds need to meet many requirements such as high precision, high efficiency, high stability and long life. However, there are some problems with the common automotive fastener injection molds, which affect the performance and service life of the molds to a certain extent.

[0003] Existing automotive fastener injection molds are usually large in size, which not only increases the manufacturing cost, but also makes the transportation, installation and maintenance of the mold more difficult. Large molds require more space during the production process, which limits the layout and optimization of the production line, thereby affecting production efficiency; the action sequence of automotive fastener injection molds usually includes multiple steps such as pumping the oil cylinder, opening the mold, closing the mold, and returning the oil cylinder. These steps need to be precisely controlled to ensure the correct operation of the mold. However, in the actual production process, due to various reasons (such as incorrect oil cylinder sequence, electrical circuit failure, etc.), the mold action may be out of control, and then the mold collision phenomenon may occur, causing mold damage, and may also affect product quality and production safety.

[0023] The fixed mold template 3 has four first springs 21 installed on its surface, an oblique spring block 9 is installed on the other end of the first spring 21, an oblique sliding block 10 is installed on the surface of the oblique sliding block 9, and wear-resistant blocks 11 are arranged between the corresponding oblique sliding blocks 10, and the wear-resistant blocks 11 are arranged in a cone shape;

[0024] Each of the two first springs 21 evenly supports the inclined elastic block 9, and the two inclined sliding blocks 10 are arranged in a dovetail shape, so as to better fit with the wear-resistant block 11;

[0025] The wear-resistant block 11 is fixedly connected to the fixed mold template 3, and two limiting grooves 23 are provided on the surface of the wear-resistant block 11. The inclined sliding block 10 is slidably connected to the corresponding limiting grooves 23, so that the wear-resistant block 11 can limit the inclined sliding block 10 to avoid the problem of the inclined sliding block 10 being loose;

[0026] The mold core 5 is installed on the surface of the fixed mold template 3. The inclined sliding block 10 and the wear-resistant block 11 penetrate the mold core 5. The mold core 5 cooperates with the flow channel plate 22 to shape the product 24.

[0027] In this embodiment, if Figure 1 As shown, a support column 14 is provided on the surface of the movable mold plate 2, and the other end of the support column 14 is connected to the mold base plate 1. The support column 14 is used to balance the pressure during injection molding. A plurality of second springs 15 are installed between the base plate and the movable mold plate 2. The second springs 15 are used to push the movable mold plate 2. A return rod 19 is provided on the surface of the base plate. The return rod 19 is inserted into the movable mold plate 2 and is slidably connected to the movable mold plate 2 to ensure that the movable mold plate 2 will not shake when sliding up and down to avoid unexpected errors.

[0028] In this embodiment, if Figure 3 As shown, a pressure strip 18 is installed on the surface of the movable mold template 2, and the slider seat 16 is slidably connected to the pressure strip 18. The pressure strip 18 can accurately limit the slider seat 16. A wear-resistant plate 20 is provided between the movable mold template 2 and the slider seat 16 to prevent the slider seat 16 and the movable mold template 2 from wearing each other. The surface of the pressure strip 18 has an arc-shaped opening, so that the pressure strip 18 is slidably connected to the return rod 19.

[0029] In this embodiment, if Figure 2 As shown, a fixed mold bottom plate 4 is installed on the surface of the fixed mold template 3, and the fixed mold bottom plate 4 provides a support point for the fixed mold template 3, so as to facilitate the external equipment to move the fixed mold template 3.

[0030] In this embodiment, if Figure 1 and Figure 2 As shown, a locking wedge 7 is provided on the edge of the surface of the fixed mold template 3, and a wear-resistant sheet 12 is installed on the surface of the locking wedge 7. The locking wedge 7 can fix various components in the mold to prevent the mold from moving and misaligning during the injection molding process. An inclined guide column 6 is installed on the side of the fixed mold template 3, and the inclined guide column 6 is plugged into the slider seat 16. A straight guide column 8 is provided on the surface of the fixed mold template 3, and the straight guide column 8 is plugged into the movable mold template 2. The function of the straight guide column 8 and the inclined guide column 6 is to ensure that the mold is correctly positioned and supported during operation to avoid errors.

[0031] In this embodiment, if Figure 1 As shown, the fixed mold template 3 is rotatably connected to the side with a locking module 13, and the movable mold template 2 is provided with a locking column corresponding to the locking module 13 on the side. The locking module 13 has a notch. The locking module 13 is rotated so that the locking module 13 is sleeved on the surface of the locking column, so that the movable mold template 2 and the fixed mold template 3 can be locked.

[0032] Specifically, when in use, after the movable mold plate 2 and the fixed mold plate 3 are molded together, the locking module 13 is used to lock the movable mold plate 2 and the fixed mold plate 3 to prevent the movable mold plate 2 and the fixed mold plate 3 from being misaligned, and the material is transported to between the mold core 5 and the runner plate 22 through the injection port on the surface of the fixed mold bottom plate 4, and then the material is divided into four parts and flows between the four inclined spring blocks 9. After the injection molding is completed, the movable mold plate 2 and the fixed mold plate 3 are cooled so that the material is cooled to form a product 24. When the product 24 is demolded, the locking module 13 is rotated to loosen the movable mold plate 2 and the fixed mold plate 3. At this time, the first spring 21 pushes the inclined spring block 9 to move, and the product 24 is cored at the same time. The inclined spring block 9 drives the inclined slide block 10 to move. When the inclined slide block 10 is stuck by the wear-resistant block 11, the product 24 is completely separated from the inclined slide block 10. This set of 4-cavity mass production molds can be made in a small mold frame, which saves more than half of the mold frame size compared to using a cylinder core pulling, and also avoids the probability of mechanical and electrical failures of the cylinder.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
