Description

Technical Field

[0001] The invention relates to the technical field of commutator processing devices, in particular to a product removing and capping device for a commutator forming process. Background Art

[0002] The product removal and capping device in the commutator molding process is one of the key equipment to ensure the production quality and efficiency of the commutator. The commutator needs to go through multiple processes in the production process, among which the molding process is a key link. And the capping part of the commutator after molding needs to be removed for subsequent processing and testing. The product removal and capping device is the key equipment used to complete this task. Its performance directly affects the production efficiency and product quality of the commutator. The working principle of the product removal and capping device usually involves various technologies such as mechanical, pneumatic or hydraulic. The product removal and capping device in the commutator molding process is mainly used to remove the molded commutator from the mold and remove its cap (such as plastic shell, bakelite powder, etc.) during the commutator production process. The device usually includes a feeding mechanism, a demoulding mechanism, a capping mechanism and a conveying mechanism. Through automatic control and high-precision design, the device can achieve efficient and accurate production, improve product quality and production efficiency, and with the continuous advancement of technology and the continuous development of the market.

[0003] After searching, the patent document (authorization announcement number is CN216831994U) is a one-piece mold structure for entering and demolding a commutator forming main mold, including: a demolding pad and a base, wherein the demolding pad is provided with a plurality of blanking through holes; a template in the pressing main mold, which is horizontally placed on the demolding pad for use, and the template in the pressing main mold has a plurality of product cavities; an entering and demolding transition plate, which is horizontally placed on the template in the pressing main mold for use, and the entering and demolding transition plate has a plurality of copper sheet ring entry holes; an entering and demolding head and a fixing plate, wherein the head fixing plate is horizontally arranged above the entering and demolding transition plate for use and slides in the vertical direction, and a plurality of entering and demolding rods are fixed at the bottom of the head fixing plate. The structure of the present invention reasonably combines the entering and demolding processes, saves the press, and improves the work efficiency.

[0004] However, the above device still has shortcomings:

[0005] After the commutator is pressed and formed, the stripping head needs to remove the formed product from the middle template. The stripping head first breaks through the molding glue inlet seal, and then strips the material. Because the punch return stroke will bring the molded product upwards into the middle template, it is necessary to strip the material repeatedly. Due to the hidden danger of leakage, there is a risk of die pressing for realizing automatic stripping. At the same time, the stripping process will also bring up the broken water inlet seal waste, resulting in waste remaining in the inner hole of the product. The material flows into the subsequent finishing process, which will cause the ash extraction pipe of the inner hole turning machine chuck to be blocked, and the turning powder will remain on the chuck, affecting the concentricity of the product clamping, resulting in the product outer circle runout out of tolerance, which has major quality risks. Therefore, operators are required to manually remove the residual seals, or increase vibration grinding and cleaning to remove the residual waste in the inner hole of the product. The above measures increase manufacturing costs; Summary of the invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a device for removing the product and the cover in the commutator forming process, which solves the problem that the formed product will be brought upward into the middle mold plate during the return stroke of the punch, and the material needs to be repeatedly removed, which has the hidden danger of leakage, and at the same time, the waste material of the broken nozzle cover will be brought up during the removal process, resulting in the waste material remaining in the inner hole of the product and the material flowing into the subsequent finishing process.

[0007] To achieve the above-mentioned purpose, the present invention proposes a product removal and capping device for a commutator forming process, comprising a workbench base, an intermediate plate is arranged above the workbench base, a tooling hole is opened inside the intermediate plate, an ejector rod outer shell is arranged inside the tooling hole, an ejector rod inner shell is slidably connected inside the ejector rod outer shell, an ejector rod inner core is slidably connected inside the ejector rod inner shell, an elastic spring is arranged inside the ejector rod inner shell, and two ends of the elastic spring are respectively fixedly connected to the ejector rod inner core and the ejector rod inner shell.

[0008] Preferably, an auxiliary template is fixedly connected to the top of the workbench base, and support columns are fixedly connected to the top of the workbench base, and the support columns are distributed on both sides of the auxiliary template.

[0009] Preferably, a slot is provided on the top of the support column, a demoulding pad base is provided above the workbench base, and convex plates are engraved on both ends of the demoulding pad base, and the convex plates are arranged in the slot.

[0010] Preferably, a plurality of placement grooves are provided on the surface of the demoulding pad base, copper sheet rings are provided inside the placement grooves, and finished products are provided inside the copper sheet rings.

[0011] Preferably, an entry and removal head fixing plate is arranged above the workbench base, the bottom of the entry and removal head fixing plate is fixedly connected to the pressing main mold middle template, the side wall of the pressing main mold middle template is fixedly connected to the entry and removal hook plate, the bottom of the entry and removal hook plate is engraved with a hook body, and a tooling plate is arranged below the pressing main mold middle template, and the tooling plate is arranged above the hook body.

[0012] Preferably, the bottom of the template in the pressing main mold is fixedly connected to an intermediate plate, a tooling hole is opened inside the intermediate plate, a middle hole is opened inside the tooling plate, the top of the inner shell of the ejector rod is fixedly connected in the tooling hole, and the side wall of the outer shell of the ejector rod is fixedly connected in the middle hole.

[0013] Preferably, a positioning pin is fixedly connected to the bottom of the middle plate, and the positioning pin is slidably connected to the inside of the tooling plate. A positioning hole is opened on the top of the demoulding pad base, and the positioning hole is arranged directly below the positioning pin.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. During the demoulding process, the ejector head fixing plate is pressed down by the oil pressure of the press machine, and the ejector rod shell contacts the finished product first. Since the force applied to the ejector rod shell at this time is only gravity and spring force, the ejector rod shell is not enough to eject the product from the middle mold until the ejector rod inner shell contacts the finished product and breaks through the tail cap of the finished product. Then, the ejector rod inner shell contacts the end face of the finished product and begins to eject the finished product from the demoulding pad base. At this time, the demoulding upper mold starts to return, and the ejector rod inner core ejects the finished product cap waste to prevent the waste from being brought into the inner hole of the finished product. At the same time, the ejector rod shell supports the tail end face of the finished product to prevent the ejector rod inner core from bringing the finished product into the demoulding pad base. The whole process realizes one-time demoulding of the finished product, separates the finished product from the cap waste, and prevents the waste from opening in the inner hole, which effectively improves the work efficiency.

[0019] 2. During the stripping process, it can effectively prevent the finished product from being brought into the demoulding pad base and the waste from remaining in the inner hole of the finished product, effectively reducing the production cost. At the same time, it can also be used in the automated pressing process to assist the demoulding of the finished product and reduce the risk of molding in the automated process.

[0033] An intermediate plate 5 is arranged above the workbench base 1, and a tooling hole 501 is opened inside the intermediate plate 5, and an ejector rod outer shell 7 is arranged inside the tooling hole 501, and an ejector rod inner shell 7 is slidably connected inside the ejector rod outer shell 7, and an ejector rod inner core 702 is slidably connected inside the ejector rod inner shell 701, and an elastic spring 703 is arranged inside the ejector rod inner shell 701, and both ends of the elastic spring 703 are respectively fixedly connected to the ejector rod inner core 702 and the ejector rod inner shell 701.

[0034] During the demoulding process, the ejector head fixing plate 4 is pressed down by the oil pressure of the press, and the ejector rod housing 7 first contacts the finished product 302. Since the force applied to the ejector rod housing 7 at this time is only gravity and spring force, the ejector rod housing 7 is not enough to eject the product from the middle mold until the ejector rod inner housing 701 contacts the finished product 302 and breaks the tail cover of the finished product 302.
