Description

Technical Field

[0001] The utility model relates to the technical field of large-stroke unloading molds, and particularly relates to a chain unloading and stacking mold. Background Art

[0002] The main function of the unloading mold is to smoothly separate the product from the mold after the forming process is completed. This is crucial for preventing product deformation, damage, or adhesion to the mold, ensuring the integrity and quality of the product. With the continuous change of market demands, the types and specifications of products are also increasing. The unloading mold needs to have good adaptability and flexibility to meet the production requirements of different products and different specifications. This requires considering various factors in the design of the unloading mold, such as product structure, material properties, production methods, etc., to ensure smooth demolding and meet quality requirements.

[0003] The existing unloading methods of molds generally rely on unloading screws or their sleeve components. However, for stacking molds involving large-stroke unloading, this traditional unloading method has significant drawbacks: it requires a relatively deep avoidance space to be opened inside the mold, which in turn increases the requirement for the mold closing height. This not only increases the requirements for the performance of the punching machine but also significantly increases the complexity and difficulty of mold design. These directly lead to an increase in the mold manufacturing cost, which has an adverse impact on production efficiency and cost control. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a chain unloading and stacking mold for large-stroke unloading, which saves unloading space, reduces the mold closing height, simplifies the mold structure, reduces the mold cost, and improves the operation efficiency.

[0005] To achieve the above purpose, the present application proposes a chain unloading and stacking mold, including:

[0006] A fixed plate, installed at the bottom of the upper template and contacting the top of the workpiece during the stacking process;

[0007] A stripping plate, used to carry the workpiece, and the stripping plate slides up and down between the upper template and the lower template;

[0008] A chain, whose bottom end is connected to both sides of the stripping plate, and the top end is connected to both sides of the fixed plate; when the mold is opened, the chain is in an extended state, and when the mold is closed, the chain is in a slack state;

[0009] A positioning and guiding block, located on the lower template and built into the stripping plate, enabling the stripping plate to slide up and down along the positioning and guiding block.

[0010] Further, when the mold is closed, the chain is naturally stacked at the gap position between the upper template and the lower template.

[0011] Furthermore, a plurality of positioning and guiding blocks are provided and located on the outer periphery of the workpiece. When the mold is closed, the top of the positioning and guiding blocks contacts the fixed plate.

[0012] Furthermore, when the mold is closed, the stripping plate fits on the upper surface of the lower template.

[0013] Furthermore, a limiting rod is provided on the upper surface of the lower template to limit the stroke of the upper template.

[0014] Even further, a guide post is provided on the upper surface of the lower template, and a guide sleeve is provided under the upper template. During the lamination process, the guide post extends into the guide sleeve to play a guiding role.

[0015] Even further, the upper template is fixed to the punching machine and moves downward under the action of the punching machine.

[0016] The above technical solution adopted by the present utility model, compared with the prior art, has the following advantages: for a large-stroke lamination mold, the chain-type stripping structure not only significantly saves the stripping space, making the overall layout of the mold more compact and reasonable, but also greatly simplifies the complexity of the mold, thereby effectively reducing the manufacturing cost and time cycle of the mold in the design, processing and assembly stages, and improving the practicality and economy of the mold.

[0017] Compared with the traditional stripping screw or sleeve assembly structure, the chain-type stripping structure makes it easy and quick to replace the workpiece, eliminating the need for the cumbersome process of screwing and unscrewing, and greatly shortening the time for mold adjustment and maintenance. In addition, the chain structure also reduces the wear and damage of the mold caused by frequent disassembly, further reducing the cost and frequency of repair and maintenance.

[0025] Please refer to Figure 1-2 , this embodiment provides a chain discharging and stacking die, including:

[0026] A fixed plate, installed at the bottom of the upper template, and in the stacking process, it contacts the top of the workpiece;

[0027] A discharging plate, used to carry the workpiece, and the discharging plate slides up and down between the upper template and the lower template; when the mold is closed, the discharging plate fits on the upper surface of the lower template;

[0028] A chain, its bottom end is connected to both sides of the discharging plate, and its top end is connected to both sides of the fixed plate; when the mold is opened, the chain is in an extended state, and when the mold is closed, the chain is in a relaxed state;

[0029] Positioning and guiding blocks, located on the lower template and built into the discharging plate, so that the discharging plate slides up and down along the positioning and guiding blocks; a plurality of the positioning and guiding blocks are provided and are located on the outer periphery of the workpiece, and when the mold is closed, the top of the positioning and guiding blocks contacts the fixed plate.

[0030] As a preferred embodiment provided by this embodiment, a limiting rod is provided on the upper surface of the lower template to limit the stroke of the upper template. A guide post is also provided on the upper surface of the lower template, and a guide sleeve is provided under the upper template. During the stacking process, the guide post extends into the guide sleeve to play a guiding role.

[0031] The working mode of the above-mentioned chain-unloading and stacking die is as follows: when the die is opened, the chain is in an extended state. After placing the workpieces to be stacked, the punching machine is operated, and the upper template and the fixed plate move slowly downward to close the die under the guidance of the positioning guide block and the guide pillar. The limit rod contacts the upper template, and the workpiece stacking is completed. At this time, the chain is in a slack state. After operating the punching machine to open the die, the workpiece can be taken out.

[0032] The effect of this embodiment is that the present application integrates the chain into the unloading mechanism and fixes the chain on the fixed plate and the unloading plate. When the die is in the closed state, the chain can be naturally stacked in the gap of the die, thus effectively saving the unloading space in the vertical direction. When the die is opened, due to the stackable characteristics of the chain, not only the taking-out space of the workpiece is significantly increased, but also the unloading stroke of the die can be flexibly adjusted according to actual needs. It not only simplifies the overall structure of the die, reduces the manufacturing cost, but also greatly improves the efficiency and flexibility of the production operation.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
