Abstract
Description
Technical Field
[0001] This utility model relates to a mold slider layer extraction mechanism, specifically a mold slider layer extraction mechanism applicable to new energy electrical control box molds. Background Technology
[0002] New energy electrical control boxes are generally complex in structure, with narrow assembly space, deep cavity, and relatively thin wall thickness. There are often deep bolt posts on the side of the product, which require the use of sliders to complete the forming process during mold manufacturing.
[0003] To reduce the occurrence of thread irregularities in the bolt post mounting holes on the outer side of the product and avoid affecting its mechanical properties, insert pins are usually designed to prevent thread irregularities caused by air shrinkage holes in the machined holes. However, this design results in a significant increase in the clamping force at the insert pins during demolding. This situation can easily cause the product to deform during demolding, and its reference position may shift. Deformed and misaligned products not only fail to pass processing and inspection, but also have an adverse impact on subsequent assembly processes, ultimately making the product unable to meet quality requirements. Summary of the Invention
[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a layered extraction mechanism for the slider of a new energy power control box mold.
[0005] The purpose of this utility model is achieved through the following technical solution: A layered extraction mechanism for a slider in a new energy electrical control box mold, comprising a hydraulic cylinder, a bracket, an ejector pin clamping plate, an ejector pin base plate, an ejector pin clamping plate, a slider seat, a slider forming position, an ejector pin, and an ejector sleeve. The hydraulic cylinder is fixedly mounted on the bracket, and the hydraulic cylinder shaft passes through the bracket and connects to the slider connecting seat. The slider connecting seat is fixedly mounted on the right plane of the ejector pin clamping plate. The ejector pin base plate is also fixedly mounted on the right plane of the ejector pin clamping plate. An ejector pin clamping plate limiting and ejection spring are fixedly mounted on the left plane of the ejector pin clamping plate. An ejector pin base plate is provided on the left side of the ejector pin clamping plate, and an ejector pin clamp is provided on the left side of the ejector pin clamping plate. The ejector clamp plate has an ejector clamp plate limiter fixedly installed on its left side. A slider seat is provided on the left side of the ejector clamp plate. A slider limiter is provided between the slider seat and the ejector clamp plate. The slider limiter is fixedly installed on the slider seat. Pressure strips are provided on both sides of the slider seat. The left end of the slider guide post is inserted into the slider seat. The right end of the slider guide post passes through the ejector clamp plate, the ejector base plate, and the ejector needle clamp plate. A slider forming position is provided on the left side of the slider seat. The two are fixed by bolts. The left end of the ejector sleeve passes through the slider forming position. The right end passes through the slider seat and the ejector clamp plate. An ejector needle is provided inside the ejector sleeve. The ejector needle is inserted from the left end of the ejector sleeve and exits from the right end, and continues to pass through the ejector base plate and the ejector needle clamp plate.
[0006] The bracket is equipped with bracket positioning pins.
[0007] A stroke box is installed on the hydraulic cylinder.
[0008] This utility model has the following advantages compared with the prior art: This invention disassembles the slider into a multi-layered composite structure, utilizing the relative sliding characteristics between layers to ensure even force distribution during mold opening and closing. This significantly reduces the risk of product sticking and deformation caused by excessive local clamping force. Simultaneously, the layered design effectively buffers friction during demolding, preventing product adhesion and pulling against the mold surface, thus reducing product deformation defects at the source. Notably, this invention eliminates complex linkage components, consisting only of a basic slider layered assembly, guide rails, and positioning devices. The simplified structure and convenient installation and debugging reduce mold manufacturing costs and facilitate subsequent maintenance and repair, providing a reliable guarantee for enterprises to achieve efficient production and stable quality control.

[0011] A layered extraction mechanism for a slider in a new energy electrical control box mold includes a hydraulic cylinder 9, a bracket 8, an ejector pin clamping plate 16, an ejector pin base plate 14, an ejector pin clamping plate 13, a slider seat 5, a slider forming position 2, an ejector pin 3, and an ejector sleeve 4. The hydraulic cylinder 9 is fixedly mounted on the bracket 8. The hydraulic cylinder shaft 11 passes through the bracket 8 and connects to the slider connecting seat 10. The slider connecting seat 10 is fixedly mounted on the right plane of the ejector pin clamping plate 16. An ejector pin base plate 17 is also fixedly mounted on the right plane of the ejector pin clamping plate 16. An ejector pin base plate 17 is fixedly mounted on the left plane of the ejector pin clamping plate 16. The device is equipped with a syringe needle clamp plate limiter 15 and an ejector spring 18. A syringe needle clamp plate 16 has a syringe base plate 14 on its left side, and a syringe clamp plate 13 on its left side. A syringe clamp plate limiter 19 is fixedly installed on the left plane of the syringe clamp plate 13. A slider seat 5 is located on the left side of the syringe clamp plate 13. A slider seat limiter 20 is provided between the slider seat 5 and the syringe clamp plate 13, and the slider seat limiter 20 is fixedly installed on the slider seat 5. Pressure strips 6 are provided on both sides of the slider seat 5. The left end of the slider guide post 12 is inserted into the slider seat 5, and the right end of the slider guide post 12... The ejector sleeve 4 passes through the ejector sleeve clamping plate 13, ejector sleeve base plate 14, and ejector sleeve pin clamping plate 16. A slider forming position 2 is located on the left side of the slider seat 5, and the two are fixed by bolts. The left end of the ejector sleeve 4 passes through the slider forming position 2, and the right end passes through the slider seat 5 and ejector sleeve clamping plate 13. An ejector sleeve pin 3 is located inside the ejector sleeve 4. The ejector sleeve pin 3 is inserted from the left end of the ejector sleeve 4 and exits from the right end, continuing to pass through the ejector sleeve base plate 14 and ejector sleeve pin clamping plate 16. By disassembling the slider into a multi-layered composite structure and utilizing the relative sliding characteristics between layers, the force on the mold is evenly distributed during the mold opening and closing process, resulting in extremely efficient operation. This significantly reduces the risk of product sticking and deformation caused by excessive local clamping force. At the same time, the layered design effectively buffers the friction during demolding, preventing the product from sticking or pulling against the mold surface, thus reducing product deformation defects at the source. It is worth mentioning that this utility model abandons complex linkage components and consists only of a basic slider layered component, guide rail and positioning device. The structure is simplified and easy to install and debug, which not only reduces the mold manufacturing cost, but also facilitates later maintenance and repair, providing a reliable guarantee for enterprises to achieve efficient production and stable quality control.
[0012] The bracket 8 is equipped with a bracket positioning pin 7, which ensures the position of the slider bracket 8 on the mold, thereby improving the coaxiality of the entire slider structure and the cylinder shaft 11 and reducing slider cylinder failure.
[0013] The hydraulic cylinder 9 is equipped with a stroke box 1, which contains a limit switch that interfaces with the machine tool signal and synchronizes with the machine tool operating system to improve the operating accuracy of the equipment.
[0014] Working principle: When the machine receives the mold closing command, the hydraulic cylinder shaft 11 pushes the slider forming position 2, ejector pin 3, and ejector sleeve 4 to the designed position on the mold to prepare for product injection molding. The ejector pin 3 is limited in position by the ejector pin clamping plate 15, and the ejector sleeve 4 is limited in position by the ejector sleeve clamping plate 19, so that it will not overtravel and cause the product to not meet the drawing requirements and become unusable. During the process of the slider structure advancing, the ejector spring 18 will also be pressed.
[0015] When the machine receives the mold closing command, the ejector spring 18 rebounds, controlling the order in which the slide forming position 2, ejector pin 3, and ejector sleeve 4 disengage from the product, reducing product deformation and sticking. When the moving and fixed molds separate to the machine's set position, under the action of the ejector spring 18, the hydraulic cylinder system first pulls the ejector pin 3, which is installed in the ejector pin clamping plate 16 and ejector pin base plate 17, away from the product. At this position, the clamping force is high, which is the main factor affecting product deformation. At this time, the slide forming position 2 has not yet disengaged from the product, and the pressure... In terms of the product, to reduce product deformation, after the ejector pin 3 separates from the product, the slider forming position 2 separates from the product and is pulled back a short distance by the oil cylinder shaft 11. At this time, the ejector 4 is still not separated from the product because the ejector spring 18 is pressing against the ejector base plate 14, which prevents the product from deforming when the mold is opened. Finally, the ejector 4 separates from the product and is pushed back by the slide limit 20 on the slider seat 5. There is a gap between the slide limit 20 and the ejector clamp plate 13 to control the time difference between the slider forming position 2 and the ejector 4 separating from the product. Finally, it should be noted that although the present invention and its advantages have been described in detail above, it should be understood that various changes, substitutions, and modifications can be made without departing from the spirit and scope of the present invention as defined by the appended claims. Furthermore, the scope of the present invention is not limited to the specific embodiments of the processes, apparatus, means, methods, and steps described in the specification. Those skilled in the art will readily understand from the disclosure of the present invention that existing and future processes, apparatus, means, methods, or steps that perform substantially the same functions or obtain substantially the same results as the corresponding embodiments described herein can be used according to the present invention. Therefore, the appended claims are intended to include such processes, apparatus, means, methods, or steps within their scope.
