Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a high-strength lightweight mold blank structure. Background Technology

[0002] In the vast and complex industrial system of automobile manufacturing, the car body mold undoubtedly plays a crucial role. As a mold used to shape the car body, it not only directly reflects the car's exterior design but also determines its structural strength, safety performance, and overall aesthetics. Genuine car body molds are typically made of high-strength, lightweight metal materials, such as high-quality carbon steel, alloy steel, and aluminum alloys. The selection of these materials ensures both the strength and rigidity of the mold and aligns with the trend towards lightweight automotive manufacturing, contributing to improved fuel economy and driving performance. With the development of the automotive industry, car body mold technology is also continuously advancing. The application of digital mold technology makes mold design more efficient and precise; the use of new materials such as high-strength steel plates further enhances the strength and lightweight nature of the molds.

[0003] However, in the existing technology, high-strength lightweight mold blanks often come with large size while pursuing lightweight. When such large-sized products are molded, although their weight is relatively light, their large volume makes it difficult for operators to find a suitable point of leverage, resulting in a time-consuming and laborious handling process, and may even cause safety accidents. Utility Model Content

[0004] The purpose of this invention is to solve the problem of inconvenience in handling products in the prior art, and to propose a high-strength and lightweight mold blank structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes a mold blank, a lower mold is provided at the bottom of the mold blank, two sets of guide rods are symmetrically provided at the top of the lower mold, an upper mold is provided at the top of each guide rod, four sets of injection grooves are provided at the bottom of the upper mold, an ejection assembly is provided between the upper mold and the injection grooves, the upper mold ejects the product in the injection grooves through the ejection assembly, and a connecting assembly is provided between the mold blank and the lower mold, the mold blank and the lower mold are detachably connected through the connecting assembly.

[0006] Preferably, the ejection assembly includes four sets of extrusion plates disposed within the injection molding tank. Each extrusion plate has a worm gear at its top, which slides within the upper mold. A fixed plate is located at the front end of the upper mold. Two sets of driven wheels rotate within the fixed plate, each driven wheel having a belt on its surface. A bracket is located at the front end of the fixed plate, and a motor is located at the front end of the bracket. The rear end of the motor is connected to the surface of the driven wheels. Each driven wheel has a drive shaft on its rear end surface, which rotates within the fixed plate. Each drive shaft has two sets of turbines on its surface, and these turbines mesh with the ejection assembly. The motor drives one set of driven wheels to rotate, which in turn drives the other set of driven wheels to rotate via the belt. Simultaneously, the two sets of driven wheels drive the two sets of turbines on the drive shaft to rotate, causing the turbines to drive the worm gear to slide up and down within the upper mold and push the extrusion plates to slide within the injection molding tank. This separates the molded product from the inner wall of the injection molding tank, facilitating product handling and further improving worker efficiency.

[0007] Preferably, the input end of the motor is connected to an external controller via a wire, and the lower mold has a groove for storing the controller, which allows the operator to remotely operate the motor through the controller and also stores the controller to prevent loss.

[0008] Preferably, the fixed plate may contain a bearing, and the rear end of the driven wheel is fixedly connected to the transmission shaft through the bearing, which can improve the stability of the driven wheel driving the transmission shaft to rotate, and at the same time reduce the damage to the bearing caused by the impact of external objects.

[0009] Preferably, the connecting assembly includes two sets of sliding grooves formed on the surface of the lower mold. A slider slides in each of the sliding grooves, and a mold blank is provided on the top of each slider. Guide grooves are formed on both sides of the lower mold surface of the mold blank, and guide blocks slide in each of the guide grooves. An insert rod is provided in each guide block, and a spring is wound on the surface of the insert rod between the guide block and the guide groove. A slot is formed on the outer wall of the mold blank corresponding to the inner end surface of the insert rod. The insert rod drives the guide block to slide in the guide groove and causes the insert rod to slide out of the slot. Then, the mold blank drives the slider to slide out of the sliding groove, which facilitates the disassembly of the mold blank by the operator. Similarly, the slot on the mold blank is slid to align with the insert rod, and the restoring force of the spring pushes the guide block to return to its original position in the guide groove and causes the insert rod to slide into the slot, thereby achieving the purpose of installing the mold blank, which facilitates the replacement of the mold blank by the operator and reduces the difficulty of disassembling and assembling the mold blank.

[0010] Preferably, one end of the spring is welded to the surface of the guide block, and the other end of the spring is welded to the inner wall of the guide groove, to prevent the spring's restoring force from causing the spring to repeatedly strike the guide block and resulting in noise pollution.

[0011] Preferably, the guide block is rectangular in shape, and the guide groove is a through hole adapted to the guide block, which allows the guide groove and the guide block to fit together fully, thereby improving the stability of the guide block sliding back and forth in the guide groove.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, a set of driven wheels is driven by a motor to rotate, and the set of driven wheels drives another set of driven wheels to rotate via a belt. The two sets of driven wheels simultaneously drive two sets of worm gears on the transmission shaft to rotate, so that the worm gear drives the worm to slide up and down in the upper mold and pushes the extrusion plate to slide in the injection molding tank, thereby separating the injection molded product in the injection molding tank from the inner wall of the injection molding tank, making it easier for workers to pick up the product and further improving the work efficiency of workers.

[0014] 2. In this utility model, the guide block is slid in the guide groove by the insert rod, and the insert rod slides out of the slot. Then, the slider is slid out of the groove by the mold blank, which makes it easier for the staff to disassemble the mold blank. Similarly, the slot on the mold blank is slid to be aligned with the insert rod, and then the restoring force of the spring pushes the guide block to return to its original position in the guide groove and slides the insert rod into the slot, thereby achieving the purpose of installing the mold blank, so as to facilitate the staff to replace the mold blank and reduce the difficulty of disassembling and assembling the mold blank.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example

[0023] like Figure 1-4 As shown, this utility model provides a high-strength and lightweight mold blank structure, including a mold blank 2. The bottom of the mold blank 2 is provided with a lower mold 1. The top of the lower mold 1 is symmetrically provided with two sets of guide rods 3. The top of each guide rod 3 is provided with an upper mold 4. The bottom of the upper mold 4 is provided with four sets of injection grooves 7. An ejection assembly 5 is provided between the upper mold 4 and the injection grooves 7. The upper mold 4 ejects the product in the injection grooves 7 through the ejection assembly 5. A connecting assembly 6 is provided between the mold blank 2 and the lower mold 1. The mold blank 2 and the lower mold 1 are detachably connected through the connecting assembly 6.

[0024] like Figure 3 As shown, the ejector assembly 5 includes four sets of extrusion plates 51 disposed in the injection tank 7. The top of the extrusion plate 51 is provided with a worm gear 52, which slides in the upper mold 4. The front end of the upper mold 4 is provided with a fixed plate 53. Two sets of driven wheels 54 rotate inside the fixed plate 53. The surface of the driven wheels 54 is provided with a belt 55. The front end of the fixed plate 53 is provided with a bracket 56. The front end of the bracket 56 is provided with a motor 57. The rear end of the motor 57 is connected to the surface of the driven wheels 54. The rear end surface of each driven wheel 54 is provided with a drive shaft 58, which rotates in the fixed plate 53. The surface of each drive shaft 58 is provided with two sets of turbines 59, which mesh with the ejector assembly 5.

[0025] The motor 57 drives a set of driven wheels 54 to rotate, which in turn drives another set of driven wheels 54 to rotate via a belt 55. The two sets of driven wheels 54 simultaneously drive the two sets of turbines 59 on the transmission shaft 58 to rotate, causing the turbines 59 to drive the worm gear 52 to slide up and down in the upper mold 4 and push the extrusion plate 51 to slide in the injection molding tank 7. This separates the injection molded product from the inner wall of the injection molding tank 7, making it easier for workers to pick up the product and further improving the work efficiency of the workers.

[0026] like Figure 3As shown, the input end of motor 57 is connected to an external controller via a wire. The lower mold 1 has a groove for storing the controller, which allows staff to remotely operate motor 57 via the controller and also stores the controller to prevent loss.

[0027] like Figure 3 As shown, a bearing can be built into the fixed plate 53. The rear end of the driven wheel 54 is fixedly connected to the transmission shaft 58 through the bearing, which can improve the stability of the driven wheel 54 driving the transmission shaft 58 to rotate, and at the same time reduce the damage to the bearing caused by the impact of external objects.

[0028] like Figure 3 and Figure 4 As shown, the connecting component 6 includes two sets of sliding grooves 61 formed on the surface of the lower mold 1. A slider 62 slides in each of the sliding grooves 61. A mold blank 2 is provided on the top of each slider 62. Guide grooves 63 are formed on the surface of the lower mold 1 on both sides of the mold blank 2. Guide blocks 64 slide in each of the guide grooves 63. Insert rods 65 are provided in each of the guide blocks 64. Springs 66 are wound on the surface of the insert rods 65 between the guide blocks 64 and the guide grooves 63. Slots 67 are formed on the outer wall of the mold blank 2 corresponding to the inner end surface of the insert rods 65.

[0029] The guide block 64 is slid in the guide groove 63 by the insert rod 65, and the insert rod 65 slides out of the slot 67. Then, the slider 62 is slid out of the slide groove 61 by the mold blank 2, which makes it easier for the staff to disassemble the mold blank 2. Similarly, the slot 67 on the mold blank 2 is slid to be aligned with the insert rod 65, and then the restoring force of the spring 66 pushes the guide block 64 to return to its original position in the guide groove 63 and slides the insert rod 65 into the slot 67, thereby achieving the purpose of installing the mold blank 2, so as to facilitate the staff to replace the mold blank 2 and reduce the difficulty of disassembling and assembling the mold blank 2.

[0030] like Figure 4 As shown, one end of the spring 66 is welded to the surface of the guide block 64, and the other end of the spring 66 is welded to the inner wall of the guide groove 63. This can fix both ends of the spring 66 and prevent the spring 66 from repeatedly hitting the guide block 64 due to its restoring force, thus preventing noise pollution.

[0031] like Figure 4 As shown, the guide block 64 is rectangular in shape, and the guide groove 63 is formed as a through hole that fits the guide block 64, so that the guide groove 63 and the guide block 64 can fit together fully, thereby improving the stability of the guide block 64 sliding back and forth in the guide groove 63.

[0032] The operating method and working principle of this device are as follows: First, injection molding is performed on the injection tank 7. Then, the lower mold 1 drives the mold blank 2 to be squeezed against the upper mold 4, so that the mold blank 2 shapes the material in the injection tank 7. When the product in the injection tank 7 can be taken out, the motor 57 drives a set of driven wheels 54 to rotate. The driven wheels 54 drive another set of driven wheels 54 to rotate through the belt 55. The two sets of driven wheels 54 simultaneously drive the two sets of turbines 59 on the transmission shaft 58 to rotate. The turbines 59 drive the worm gear 52 to slide up and down in the upper mold 4 and push the extrusion plate 51 to slide in the injection tank 7, thereby separating the injection molded product in the injection tank 7 from the inner wall of the injection tank 7, making it easier for the staff to take out the product.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
