Description

Technical Field

[0001] This utility model relates to the field of metal stamping die technology, specifically a forming die for metal frame processing. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials into parts. Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts.

[0003] According to the search, the existing Chinese patent announcement number is CN119327986A. This patent uses an air valve to clean up metal shavings and waste generated by the mold over a long period of use, so as to avoid affecting the subsequent mold stamping.

[0004] Although the above-mentioned patent can handle metal chips and waste generated by die stamping, the above structure still has the following problems: the device cannot position and fix the die, and the die is easily displaced due to vibration when the upper template is pressed down, which affects the die stamping. In addition, the stamped finished product requires manual prying of the material with tools, which is troublesome.

[0005] To address the aforementioned issues, a forming mold for metal frame processing is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a forming mold for metal frame processing, which solves the problem of fixing the mold and automatically demolding after stamping in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a forming mold for metal frame processing, including a base, guide pillars fixedly connected to both sides of the top of the base, sleeves slidably connected to the top of each guide pillar, an upper mold base fixedly connected to the top of the sleeves, a hydraulic cylinder fixedly connected to the top of the upper mold base, a piston rod fixedly connected to the output end of the hydraulic cylinder and slidably connected to the piston rod and the upper mold base, an upper template fixedly connected to the bottom of the piston rod, inner guide pillars fixedly connected to the four sides of the top of the base, a lower mold base slidably connected to the middle of the four inner guide pillars, a lower template fixedly connected to the top of the lower mold base, first sliders slidably connected to both sides of the lower template, and a second slider provided on the outer side of the first slider;

[0008] By adopting the above technical solution, the mold is fixed by sliding the first slider and the second slider, which avoids the device from vibrating and causing the mold to shift when the upper template is pressed down, thus preventing stamping failure.

[0009] As a further description of the above technical solution: a second slider is slidably connected to both sides of the top of the lower mold base, and a horizontally arranged spring is provided on the inner side of the second slider, with one end of the horizontally arranged spring being fixedly connected to the outer side of the first slider.

[0010] By adopting the above technical solution, the second slider drives the first slider to slide in conjunction with the horizontally arranged spring, and the sliding position of the two sliders is fixed in the lower mold base by the slide groove.

[0011] As a further description of the above technical solution: the bottom inner sides of the two sleeves are rotatably connected to support rods, and the bottom ends of the support rods are rotatably connected to the outer side of the second slider;

[0012] By adopting the above technical solution, when the upper mold base presses down and drives the sleeve to move down, the slide block is driven to slide through the support rod, so that the mold is automatically fixed when the upper mold base presses down, reducing the number of manual operation steps.

[0013] As a further description of the above technical solution: a pad is fixedly connected to the top of the base, and a groove is opened on the top of the pad. A horizontally arranged spring is fixedly connected to both sides of the inner wall of the groove. One end of the horizontally arranged spring is fixedly connected to the crank slider below, and the crank slider below slides in the groove. A crank is slidably connected to the inner wall of the crank slider below. The top of the crank is slidably connected to the crank slider above. A release plate is fixedly connected to the top of the crank slider above, and the release plate is located inside the lower template.

[0014] By adopting the above technical solution, when the upper and lower templates come into contact, the ejector plate is squeezed and moved downwards. After the stamping is completed, the upper template rises and the horizontally arranged spring in the pad returns, driving the crank slider and ejector plate to rise, thereby realizing the automatic demolding of the mold.

[0015] As a further description of the above technical solution: a limiting bracket is fixedly connected to the rear side of the base, a motor is fixedly connected to the top of the limiting bracket, a threaded rod is fixedly connected to the output end of the motor and the threaded rod is rotatably connected to the limiting bracket, the rear end of the connector passes through and is threadedly connected to the threaded rod, and the rear side of the connector is slidably connected to the limiting slot of the limiting bracket, and the bottom of the front end of the connector is fixedly connected to the upper mold base.

[0016] By adopting the above technical solution, the upper template is raised and lowered by rotating the threaded rod driven by the motor and moving the connecting parts up and down in the limiting groove.

[0017] As a further description of the above technical solution: a sliding groove is provided on the front side of the limiting bracket;

[0018] By adopting the above technical solution, the vertical lifting distance of the upper template is determined, so that the upper template will not descend too far, causing excessive damage to the springs and other structures of the lower template.

[0019] As a further description of the above technical solution: each of the four inner guide pillars has a vertically arranged spring on its outer wall, and one end of the spring is fixedly connected to the lower mold base;

[0020] By adopting the above technical solution, after the upper template is pressed down and contacts the lower template, the vibration of the device is reduced by the elasticity of the spring, thus achieving the effect of shock absorption.

[0021] As a further description of the above technical solution: holes are provided on all four sides of the upper mold base;

[0022] By adopting the above technical solution, the position of the upper template is ensured by the holes and inner guide pillars when the upper template is pressed down, ensuring that the upper template will not have an angular deviation that affects the stamping and forming of the mold.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] 1. The present invention provides a forming mold for metal frame processing. First, the upper template part and the lower template part are linked by the support rod. When the upper template is pressed down, the support rod is displaced and drives the second slider to slide. The elasticity of the spring drives the first slider to slide inward and automatically fix the mold.

[0025] 2. The present invention provides a forming mold for metal frame processing. When the upper template is pressed down, it squeezes the lower template, causing the crank slider and the crank to descend in linkage and the spring to be in a squeezed state. After the mold is stamped and formed, the upper template rises, the spring returns, and the crank slider and the slider rise and slide, driving the demolding plate to rise and automatically demold the mold.

[0037] Working Principle: This utility model discloses a forming mold for metal frame processing. When the mold is stamped, the upper mold and the lower mold are fixed on the upper template 12 and the lower template 4, respectively. The motor 10 is started to drive the threaded rod 15 to rotate, which in turn drives the connecting piece 9, the upper mold base 7 and the upper template 12 to move down. During the downward movement, the support rod 19 drives the second slider 20 to slide inward. The horizontally arranged spring 14 in the middle causes the first slider 18 to slide due to compression, which in turn automatically fixes the lower mold to prevent the mold position from shifting. When the upper template 12 contacts the lower template 4, the vertically arranged spring 14 compresses and dampens. The hydraulic cylinder 8 is started to press the upper mold down. The ejector plate 5 descends, which drives the crank slider 21 and the crank 22 to descend. The horizontally arranged spring 14 is compressed by force. After the extrusion molding is completed, the upper mold base 7 rises. The horizontally arranged spring 14 returns to its original position, which drives the crank slider 21 and the crank 22 to rise. The ejector plate 5 drives the lower mold to rise, realizing the automatic demolding of the mold.
