Description

Technical Field

[0001] This utility model relates to the field of lithium battery cover plate mold technology, specifically to a battery cover plate production mold. Background Technology

[0002] In the manufacturing of battery covers, traditional production methods rely primarily on conventional mold structures to complete the injection molding process. Previously, during battery cover injection molding, after the mold closes and injection is performed, residual injection material easily remains on the mold surface. This leads to difficulties in demolding the battery cover during subsequent production, affecting production efficiency and potentially causing poor surface quality such as scratches and burrs, reducing product yield. The traditional method for solving the demolding problem is manual spraying of release agent. Manual operation has several drawbacks. Firstly, it's difficult to ensure uniform release agent spraying; excessive spraying in certain areas wastes release agent, increasing production costs, while insufficient spraying fails to effectively demold. Secondly, manual operation is inefficient, extending production cycles during large-scale production and failing to meet the demands of high-efficiency manufacturing. Furthermore, manual operation makes it difficult to precisely control the spraying area, potentially spraying release agent into unnecessary areas of the mold, affecting its normal use and subsequent maintenance. Therefore, there is an urgent need for a battery cover production mold that can efficiently, uniformly, and precisely spray release agent. Utility Model Content

In order to solve the drawbacks and defects mentioned in the background art, this technical solution has the following contents: it includes a cover mold component, and release agent spraying components are slidably arranged on the left and right sides of the cover mold component. The cover mold component includes a lower mold, an upper mold located above the lower mold, and a battery cover workpiece located between the lower mold and the upper mold. The release agent spraying assembly includes two electrically controlled slide rails fixed on the left and right side walls of the lower mold, and an electrically controlled slider that is synchronously slidable in the slide rail tracks. A U-shaped bracket is fixedly connected to the side wall of the electrically controlled slider away from the slide rails. A release agent liquid tank is fixedly connected to the left side wall of the U-shaped bracket. A small water pump is fixedly connected to the top surface of the U-shaped bracket.

[0014] To provide a clearer explanation and illustration of the technical solution and implementation of this utility model, several preferred specific embodiments for implementing the technical solution of this utility model are described below. The following description is merely exemplary and not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these drawings, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically illustrate the concept and principle of the embodiments of this disclosure and do not necessarily show the specific dimensions and proportions of the various embodiments of this disclosure. The technical solution of this utility model will be clearly and completely described below in conjunction with embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model.

[0015] Example 1: A battery cover production mold includes a cover mold component 1, with release agent spraying components 2 slidably arranged on the left and right sides of the cover mold component 1. The cover mold component 1 consists of a lower mold 1-1, an upper mold 1-3 located above the lower mold 1-1, and a battery cover workpiece 1-2 located between the two. The top surface of the upper mold 1-3 is connected to the telescopic shaft of a hydraulic press, and the bottom surface of the lower mold 1-1 is connected to a working platform. In the release agent spraying components 2, two electrically controlled slide rails 2-1 are fixed on the left and right side walls of the lower mold 1-1, with the right section extending to the right side of the lower mold 1-1. The electrically controlled slider 2-2 is synchronously slidably arranged in the track of the electrically controlled slide rails 2-1, and a U-shaped bracket 2-9 is fixedly connected to the side wall away from the electrically controlled slide rails 2-1. The release agent liquid tank 2-3 is fixed to the left side wall of the U-shaped bracket 2-9. A liquid level sensor is located on the inner wall of the tank. The top has an inlet and a through-hole for the suction hose 2-5 to pass through. The gap between the through-hole and the suction hose 2-5 is sealed with a sealing ring. A digital display screen 2-4 for displaying liquid level data is installed on the rear side wall. A small water pump 2-6 is fixed to the top surface of the U-shaped bracket 2-9. Its suction end is connected to the suction hose 2-5, which extends to the bottom of the release agent liquid tank 2-3. Its delivery end is connected to a delivery pipe 2-7, which passes through the U-shaped bracket 2-9. Several manifolds 2-8 are evenly spaced and fixed to the bottom of the delivery pipes 2-7. Atomizing nozzles 2-10 are fixed to the bottom of the manifolds 2-8. The spraying ends of the atomizing nozzles 2-10 on both sides face the inside of the lower mold 1-1, while the spraying end of the middle atomizing nozzle 2-10 faces upwards towards the inside of the upper mold 1-3. Two photoelectric position sensors are fixed to the bottom surface of the U-shaped bracket 2-9 to monitor the start and end points of the release agent spraying. During operation, the hydraulic press telescopic shaft drives the upper mold 1-3 to press down, and the electric control slider 2-2 moves the U-shaped bracket 2-9 to a position that does not affect mold closing. After injection molding is completed, the electric control slider 2-2 moves the U-shaped bracket 2-9 to a suitable position, and the small water pump 2-6 operates to extract the release agent from the release agent tank 2-3, which is then sprayed out through the infusion pipe 2-7 and manifold 2-8 from the atomizing nozzle 2-10. The photoelectric position sensors monitor the start and end points of the spraying.

[0016] Example 2: A battery cover plate production mold. The cover plate mold component 1 has the same structure as in Example 1. In the release agent spraying components 2 on both sides, the electrically controlled slide rail 2-1 is also fixed to the left and right side walls of the lower mold 1-1, with the right section extending. The electrically controlled slider 2-2 slides synchronously back and forth in the track and is connected to the U-shaped bracket 2-9. The release agent liquid tank 2-3 is fixed to the left side wall of the U-shaped bracket 2-9. It has a liquid level sensor inside, an inlet at the top, and a sealed through-hole through which the liquid extraction hose 2-5 passes. There is a digital display screen 2-4 on the rear side. A small water pump 2-6 is fixed to the top of the U-shaped bracket 2-9. It is connected to the manifold 2-8 and the atomizing nozzle 2-10 through the liquid extraction hose 2-5 and the infusion pipe 2-7. The orientation of the atomizing nozzle 2-10 is the same as in Example 1. There is a photoelectric position sensor at the bottom of the U-shaped bracket 2-9. During the production process, when it is necessary to spray release agent onto the mold, the electrically controlled slide rail 2-1 and the electrically controlled slider 2-2 work together to move the U-shaped bracket 2-9 to the working position. The small water pump 2-6 is started to draw the release agent from the release agent tank 2-3 and deliver it to the manifold 2-8 through the infusion pipe 2-7. Finally, the atomizing nozzle 2-10 sprays the release agent evenly onto the lower mold 1-1 and the upper mold 1-3. The photoelectric position sensor monitors the start and end points of the spray in real time to ensure accurate spraying range.

[0017] Example 3: A battery cover plate production mold, the cover plate mold component 1 includes a lower mold 1-1, an upper mold 1-3, and a battery cover plate workpiece 1-2. The upper mold 1-3 is connected to the telescopic shaft of a hydraulic press, and the lower mold 1-1 is connected to a working platform. In the release agent spraying assembly 2, the electrically controlled slide rail 2-1 is fixed to the left and right side walls of the lower mold 1-1 and extends to the right. The electrically controlled slider 2-2 slides synchronously back and forth in its track and is connected to a U-shaped bracket 2-9. The release agent liquid tank 2-3 is fixed on the left side of the U-shaped bracket 2-9. The tank has a liquid level sensor, a liquid inlet and a sealed liquid extraction hose 2-5 through hole at the top, and a digital display screen 2-4 at the rear. The small water pump 2-6 at the top of the U-shaped bracket 2-9 is connected to a manifold 2-8 and an atomizing nozzle 2-10 through the liquid extraction hose 2-5 and the delivery pipe 2-7. The atomizing nozzle 2-10 is oriented as in Example 1. The bottom of the U-shaped bracket 2-9 has a photoelectric position sensor. At the start of production, the position of the U-shaped bracket 2-9 is adjusted to avoid affecting mold closing. After injection molding is completed, the U-shaped bracket 2-9 is moved to the working position. The small water pump 2-6 draws the release agent from the release agent tank 2-3 and delivers it to the atomizing nozzle 2-10 for spraying through the infusion pipe 2-7 and manifold 2-8. The photoelectric position sensor monitors the starting point and ending point of the spraying to ensure that the release agent is evenly sprayed on the mold surface.

[0018] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows: The electrically controlled slider 2-2 slides synchronously back and forth in the electrically controlled slide rail 2-1, driving the U-shaped bracket 2-9 to the working position. At this time, two photoelectric position sensors on the bottom surface of the U-shaped bracket 2-9 start working to monitor the start and end points of the release agent spraying. Then, the release agent in the release agent tank 2-3, which is fixedly connected to the left side wall of the U-shaped bracket 2-9, is pumped by a small water pump 2-6 fixedly connected to its top surface. The pump 2-6's suction end is connected to a suction hose 2-5 that penetrates to the bottom of the release agent tank 2-3's inner cavity to extract the release agent. The liquid level sensor on the inner side wall of the release agent tank 2-3 can monitor the liquid level, and the inlet on its top surface is used to replenish the release agent. The digital display screen 2-4 on the rear side wall can display the liquid level data. The gap between the through hole of the liquid extraction hose 2-5 on the top surface and the liquid extraction hose 2-5 is sealed by a sealing ring; the liquid delivery end of the small water pump 2-6 is connected to the liquid delivery pipe 2-7 that passes through the U-shaped bracket 2-9 to deliver the release agent. Several manifolds 2-8 fixedly connected at equal intervals on the bottom surface of the liquid delivery pipe 2-7 divert the release agent. The atomizing nozzles 2-10 fixedly connected to the bottom end of the manifolds 2-8 start working. The spraying ends of the atomizing nozzles 2-10 on both sides face the inside of the lower mold 1-1, and the spraying end of the atomizing nozzle 2-10 in the middle section faces upward towards the inside of the upper mold 1-3, so as to evenly spray the release agent on the lower mold 1-1 and the upper mold 1-3; after the spraying is completed, the electric control slider 2-2 drives the U-shaped bracket 2-9 to move back to the initial position, waiting for the release agent spraying work after the next injection molding is completed.

[0019] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
