Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a composite blanking mold for electrode sheets. Background Technology

[0002] Electrodes are common components in electronic devices. They are mainly produced by stamping and blanking between raw material plates and molds. During the blanking process, the stamping mechanism presses the raw material plate into the mold and then punches it out to obtain the product.

[0003] However, the molds currently used in electrode production are quite troublesome to separate the finished product from the raw material plate during the blanking process, and the finished product cannot be directly demolded after being knocked into the mold. Therefore, a complicated demolding operation is required later, which has some limitations. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0005] Therefore, the purpose of this utility model is to provide a composite blanking mold for electrode sheets, which can replace the mold used in the traditional blanking process of electrode sheet production, and avoid the problems of the finished product being difficult to separate from the raw material plate during stamping blanking and the finished product being unable to be directly demolded.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0007] An electrode composite blanking die, comprising:

[0008] The mold mechanism has a first state before and after stamping blanking, and a second state during stamping blanking. When the mold mechanism switches from the second state to the first state, the blanked electrode product automatically completes demolding.

[0009] A separation mechanism is movably mounted on the mold mechanism, wherein when the mold mechanism switches from the first state to the second state, the separation mechanism is automatically driven to work and cut and separate the stamped finished product from the raw material plate.

[0010] As a preferred embodiment of the electrode composite blanking mold of this utility model, the mold mechanism includes a mold base with a mold groove on the top and a template located in the mold groove.

[0011] As a preferred embodiment of the electrode composite blanking mold of this utility model, the mold base is provided with a storage groove;

[0012] The separation mechanism includes a cutting component movably installed in the storage slot and adapted to the template, and a drive component installed in the mold slot that drives the cutting component to extend out of the storage slot when the template is stamped and automatically drives the cutting component to retract into the storage slot after the template is stamped.

[0013] As a preferred embodiment of the electrode composite blanking mold of this utility model, the inner wall of the mold groove is provided with a plurality of ventilation holes communicating with the receiving groove.

[0014] The drive assembly includes a housing with an air guide tube on its sidewall, an elastic element located inside the housing, and a telescopic block with one end slidably connected to the inner wall of the housing and the other end extending out of the housing and connected to the bottom of the template. The end of the air guide tube away from the housing is connected to the vent hole.

[0015] In a preferred embodiment of the electrode composite blanking mold described in this utility model, when the mold mechanism is in the first state, the top of the template extends out of the mold groove.

[0016] In a preferred embodiment of the electrode composite blanking mold of this utility model, the driving assembly is provided in multiple sets, and the air guide pipes of the multiple sets of driving assemblies are respectively connected to multiple air vents.

[0017] Compared with the prior art, the beneficial effects of this utility model are that when the raw material plate on the die mechanism is punched and blanked by the stamping mechanism, the die mechanism switches from the first state to the second state. At this time, the separation mechanism automatically starts to work to cut and separate the raw material plate from the blanked electrode product. After the punching and blanking is completed, the die mechanism returns from the second state to the first state, and the blanked electrode product is automatically demolded from the die mechanism. This replaces the die used in the traditional electrode production blanking process and avoids the problems of the finished product being difficult to separate from the raw material plate and the blanked product being unable to be directly demolded during the punching and blanking process.

[0029] This utility model provides a composite blanking mold for electrode sheets, which replaces the mold used in the traditional blanking process of electrode sheet production. It avoids the problems of the finished product being difficult to separate from the raw material plate during stamping blanking and the finished product being unable to be directly demolded.

[0030] Figures 1-6The diagram shown is a structural schematic of a composite blanking die for electrode sheets according to this utility model. Please refer to [link / reference]. Figures 1-6 This paper provides a detailed introduction to the composite blanking die for this type of electrode sheet.

[0031] Example 1

[0032] refer to Figures 1-5 This utility model discloses an electrode composite blanking mold, the main part of which includes a mold mechanism 100 and a separation mechanism 200.

[0033] The mold mechanism 100 is used to form finished electrode sheets when stamping the raw material plate. The mold mechanism 100 has a first state before stamping and blanking and a second state during stamping and blanking. When the mold mechanism 100 switches from the second state to the first state, the blanked electrode sheet is automatically demolded. Thus, when the mold mechanism 100 switches from the second state during stamping and blanking to the first state, the blanked electrode sheet is automatically demolded from the mold mechanism 100.

[0034] The separation mechanism 200 is used to automatically cut and separate the raw material plate and the finished electrode sheet formed during stamping when the mold mechanism 100 is in the second state. The separation mechanism 200 is movably installed on the mold mechanism 100. When the mold mechanism 100 switches from the first state to the second state, the separation mechanism 200 is automatically driven to work and cut and separate the stamped finished product and the raw material plate. Then, when the mold mechanism 100 is in the second state when the material is being stamped and blanked, the separation mechanism 200 automatically starts to work and automatically cuts and separates the stamped finished electrode sheet and the raw material plate.

[0035] In this embodiment, the specific usage process is as follows: The raw material plate is placed on the mold mechanism 100. During the stamping and blanking process, the mold mechanism 100 switches from the first state to the second state. At the same time, the separation mechanism 200 automatically starts working to separate the stamped electrode product from the raw material plate and complete the blanking. After the stamping is completed, when the mold mechanism 100 returns to the first state, the blanked electrode product is automatically demolded from the mold mechanism 100 without the need for subsequent demolding operations, which greatly improves the blanking efficiency.

[0036] Example 2

[0037] Based on Example 1, and referring to Figures 1-6 The mold mechanism 100 includes a mold base 110 with a mold groove 110a on the top and a template 120 located in the mold groove 110a. The mold base 110 is used to install the separation mechanism 200 and the template 120. The mold groove 110a is used to facilitate the installation of the template 120. The template 120 is used to cooperate with the raw material plate to support the finished electrode sheet when the raw material plate is stamped.

[0038] Example 3

[0039] Based on Example 2, and referring to Figures 1-6 The mold base 110 is provided with a storage groove 110b for convenient installation of the cutting part 210;

[0040] The separation mechanism 200 includes a cutting element 210 movably installed in the receiving groove 110b and adapted to the template 120, and a drive assembly 220 installed in the mold groove 110a. When the template 120 is stamped, the cutting element 210 is driven to extend out of the receiving groove 110b, and when the template 120 is stamped, the cutting element 210 is automatically driven to retract into the receiving groove 110b. The cutting element 210 is used to cut and separate the raw material plate and the stamped electrode product after extending out of the receiving groove 110b. The drive assembly 220 is used to drive the cutting element 210 to extend out of the receiving groove 110b after the template 120 is stamped into the mold groove 110a.

[0041] In this embodiment, the inner wall of the mold groove 110a is provided with a plurality of ventilation holes 110a-1 that communicate with the storage groove 110b, so as to facilitate the air compressed inside the housing 220a to enter the storage groove 110b.

[0042] The drive assembly 220 includes a housing 220a with an air guide pipe 220a-1 on its sidewall, an elastic element 220b located inside the housing 220a, and a telescopic block 220c with one end slidably connected to the inner wall of the housing 220a and the other end extending out of the housing 220a and connected to the bottom of the template 120. The housing 220a is used to facilitate the installation of the elastic element 220b and the telescopic block 220c. The elastic element 220b is used to lift the telescopic block 220c when the template 120 is not being stamped, thereby pushing the template 120 out of the mold groove 110a. When the template 120 is being stamped, the telescopic block 220c is used to squeeze into the housing 220a. The end of the air guide pipe 220a-1 away from the housing 220a is connected to the vent hole 110a-1.

[0043] In this embodiment, when the mold mechanism 100 is in the first state, the top of the template 120 extends out a mold groove 110a, which is used to facilitate the removal of the punched-out electrode product from the top of the template 120 after the stamping blanking is completed, thereby improving the demolding efficiency.

[0044] In this embodiment, the drive assembly 220 is provided in multiple sets. The air guide pipes 220a-1 of the multiple drive assemblies 220 are respectively connected to multiple air vents 110a-1. When the template 120 is pressed, the air in the receiving groove 110b expands rapidly to drive the cutting piece 210 to rise, thereby improving the separation efficiency of the formed electrode sheet and the raw material plate.

[0045] In this embodiment, the specific workflow is as follows: When stamping and blanking is performed, the raw material plate cooperates with the template 120 to obtain the formed electrode sheet. As the template 120 is squeezed and moves downward, the telescopic block 220c squeezes the elastic member 220b downward. The air in the housing 220a enters the receiving groove 110b through the air guide pipe 220a-1 and the air hole 110a-1. After the air pressure inside the receiving groove 110b increases, it drives the cutting member 210 to extend upward, thereby cutting and separating the raw material plate from the formed electrode sheet. After the stamping and blanking is completed, the elastic member 220b is reset, pushing the template 120 and the blanked electrode sheet product on the top of the template 120 out of the mold groove 110a, thereby directly demolding it and improving the efficiency of electrode blanking production.

[0046] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
