Description

Technical Field

[0001] This utility model relates to the field of product demolding technology, and in particular to a core-pulling design mechanism suitable for product demolding. Background Technology

[0002] Product demolding refers to the process of removing a formed product from a mold during the product molding process. In the manufacturing industry, many products are formed using molds, such as plastic products, metal castings, and rubber products. After the product has undergone processes such as heating, cooling, and solidification in the mold to achieve the designed shape and performance, it needs to be separated from the mold using certain methods; this is demolding. In existing technologies, some products have high clamping forces during demolding, and normal ejection cannot meet the demolding requirements. Utility Model Content

[0003] The purpose of this invention is to provide a core-pulling design mechanism suitable for product demolding, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a core-pulling design mechanism suitable for product demolding, comprising: a separation plate and a lower mold, a lifting assembly provided between the separation plate and the lower mold, the lifting assembly including a cylinder and a spring, an mounting shell installed on the inner wall of the separation plate, an mounting seat installed on the top of the mounting shell, a core component installed on the top of the mounting seat, a demolding module installed on the inner wall of the lower mold, a core-pulling block installed on the inner wall of the demolding module, and the inner wall of the core-pulling block sleeved on the surface of the core component.

[0005] In a preferred embodiment, the number of lifting components is four, with the top of cylinder one mounted on the inner wall of the lower mold and the bottom of cylinder one mounted on the inner wall of the separation plate.

[0006] In a preferred embodiment, the inner wall of the spring is sleeved on the surface of the cylinder, the top of the spring is connected to the inner wall of the lower mold, and the bottom of the spring is mounted on the top of the separation plate.

[0007] In a preferred embodiment, cylinders two are installed at the four corners of the bottom of the lower mold inner wall, and the surfaces of cylinders two are installed on the inner wall of the demolding module.

[0008] In a preferred embodiment, motors are installed at both ends of the bottom of the inner wall of the mounting housing, and fan blades are installed at the output end of the motors.

[0009] In one preferred embodiment, the surface of the mounting housing is provided with multiple air vents.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] 1. In this utility model, the separation plate and the lower mold are separated by starting the cylinder. The lower mold will drive the core-pulling block installed on the inner wall of the demolding module to rise. The core-pulling block is sleeved on the surface of the core part. The rise of the core-pulling block will drive the product to rise, so that the core part can be pulled out of the product. This realizes that the PIN hole part is pulled out of the product first, reducing the clamping force of the product on the part, making the subsequent demolding faster and the device more perfect.

[0012] 2. This utility model uses motors installed at both ends of the inner wall of the mounting housing to drive the fan blades to rotate, causing the surrounding air to circulate and be blown out through the air vents to cool the product, thus making the device more complete.

[0021] 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.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a core-pulling design mechanism suitable for product demolding, comprising: a separation plate 1 and a lower mold 2, a lifting assembly 3 provided between the separation plate 1 and the lower mold 2, the lifting assembly 3 including a cylinder 301 and a spring 302, an mounting shell 4 installed on the inner wall of the separation plate 1, an mounting seat 5 installed on the top of the mounting shell 4, a core 6 installed on the top of the mounting seat 5, a demolding module 7 installed on the inner wall of the lower mold 2, a core-pulling block 8 installed on the inner wall of the demolding module 7, and the inner wall of the core-pulling block 8 sleeved on the surface of the core 6.

[0023] Specifically: When the device is put into use, the lifting assembly 3 set between the separating plate 1 and the lower mold 2 is activated to separate the separating plate 1 and the lower mold 2. The bottom of the mounting shell 4 is installed on the bottom of the inner wall of the separating plate 1, the mounting base 5 is installed on the top of the mounting shell 4, the core part 6 is installed on the top of the mounting base 5, the demolding module 7 is installed on the inner wall of the lower mold 2, and the core-pulling block 8 is installed on the inner wall of the demolding module 7. The inner wall of the core-pulling block 8 is fitted onto the surface of the core part 6. When the separating plate 1 and the lower mold 2 are separated, the lower mold 2 will drive the core-pulling block 8 installed on the inner wall of the demolding module 7 to rise. The rise of the core-pulling block 8 will drive the product to rise, so that the core part 6 can be pulled out of the product. This realizes that the PIN hole part is pulled out of the product first, reducing the clamping force of the product on the part, making the subsequent demolding faster and making the device more perfect.

[0024] In one embodiment, the number of lifting components 3 is four. The top of cylinder 301 is installed on the inner wall of the lower mold 2, the bottom of cylinder 301 is installed on the inner wall of the separation plate 1, the inner wall of spring 302 is sleeved on the surface of cylinder 301, the top of spring 302 is connected to the inner wall of the lower mold 2, and the bottom of spring 302 is installed on the top of the separation plate 1.

[0025] Specifically: By using four lifting components 3, the separation plate 1 and the lower mold 2 can be better separated. Activating cylinder 301 extends cylinder 301. The top of cylinder 301 is installed on the inner wall of the lower mold 2, and the bottom is installed on the inner wall of the separation plate 1, opening the separation plate 1 and the lower mold 2. This causes spring 302 to extend. After the PIN hole part is removed from the product, cylinder 301 retracts, causing spring 302 to retract as well, bringing the separation plate 1 and the lower mold 2 together, thus improving the device.

[0026] In one embodiment, cylinders 2 and 9 are installed at the four corners of the bottom of the inner wall of the lower mold 2, and the surfaces of cylinders 2 and 9 are installed on the inner wall of the demolding module 7.

[0027] Specifically: After the PIN hole part is removed from the product, the cylinders 2 and 9 installed at the four corners of the bottom of the inner wall of the lower mold 2 are activated. The surface of the cylinders 2 and 9 is installed on the inner wall of the demolding module 7. The extension of the cylinders 2 and 9 drives the demolding module 7 to rise, so that the demolding module 7 drives the core-pulling block 8 to eject the product on the top of the core part 6, thereby making the product easier to demold and making the device more perfect.

[0028] In one embodiment, motors 10 are installed at both ends of the bottom of the inner wall of the mounting housing 4, fan blades 11 are installed at the output end of the motors 10, and multiple air vents 401 are opened on the surface of the mounting housing 4.

[0029] Specifically: During the injection molding process, after the raw material enters the device, the motors 10 installed at both ends of the bottom of the inner wall of the mounting shell 4 are started to drive the fan blades 11 to rotate, which drives the surrounding air to circulate and blow it out through the air vents 401 on the surface of the mounting shell 4, so as to cool the product better and make the device more perfect.

[0030] Working Principle: When the device is started, cylinder 301 is extended by activating it. The top of cylinder 301 is installed on the inner wall of the lower mold 2, and the bottom is installed on the inner wall of the separation plate 1, opening the separation plate 1 and the lower mold 2. This causes spring 302 to extend. The bottom of the mounting shell 4 is installed on the bottom of the inner wall of the separation plate 1, the mounting base 5 is installed on the top of the mounting shell 4, the core 6 is installed on the top of the mounting base 5, the ejector module 7 is installed on the inner wall of the lower mold 2, and the core-pulling block 8 is installed on the inner wall of the ejector module 7. The inner wall of the core-pulling block 8 fits over the surface of the core 6. When the separation plate 1 and the lower mold 2 separate, the lower mold 2 will cause the core-pulling block 8 installed on the inner wall of the ejector module 7 to rise. The rise of the core-pulling block 8 will cause the product to rise, allowing the core 6 to be extracted from the product. The device first removes the PIN hole part from the product to reduce the clamping force of the product on the part. Then, by activating the cylinders 2 and 9 installed at the four corners of the bottom of the inner wall of the lower mold 2, the cylinders 2 and 9 are mounted on the inner wall of the demolding module 7. The extension of the cylinders 2 and 9 drives the demolding module 7 to rise, which in turn drives the core-pulling block 8 to eject the product from the top of the core part 6. This allows the product to be demolded more effectively, making the device more complete. During the injection molding process, after the raw material enters the device, the motors 10 installed at both ends of the bottom of the inner wall of the mounting shell 4 are activated to drive the fan blades 11 to rotate. This causes the surrounding air to circulate and be blown out through the air vents 401 on the surface of the mounting shell 4, which in turn blows air onto the product, allowing the product to be cooled more effectively, making the device more complete.

[0031] 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.
