Description

Technical Field

[0001] This utility model relates to the field of hardware accessories production technology, and in particular to an anti-jamming mold structure. Background Technology

[0002] In the production process of automotive parts, some small cylindrical metal parts are generally produced by stamping, stretching, and rotary cutting. Rotary cutting is the last step in the production of metal parts and is usually done by rotary cutting equipment. The workpiece is placed on the material support mold, and then the workpiece is supported by a telescopic and resetable support rod. The rotary cutting mechanism of the rotary cutting equipment applies pressure to wrap the workpiece, and then rotary cutting is performed to separate the workpiece from the workpiece plate. After rotary cutting, the rotary cutting mechanism and the support rod will retract and reset, allowing the workpiece to detach from the support rod, completing the unloading operation.

[0003] In the prior art, when the veneer cutting mechanism of the veneer cutting equipment veneers the workpiece, the veneer cutting mechanism wraps and squeezes the workpiece, which causes the connecting ring at the connection between the workpiece plate and the workpiece to be deformed by force, causing the plate and the veneered workpiece to be stuck together and difficult to separate, affecting the overall production efficiency of the workpiece. To this end, we propose an anti-jamming mold structure. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an anti-jamming mold structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-jamming mold structure, including a material plate support frame, a base provided at the bottom end of the material plate support frame, a mold groove opened inside the material plate support frame, an auxiliary cutting mechanism provided inside the mold groove, the auxiliary cutting mechanism being used to cut the reserved groove of the material strip, a support rod provided at the top end of the material plate support frame, a material ejection mechanism provided at the top end of the support rod, the material ejection mechanism being used to assist in material ejection, and a workpiece provided at the top end of the material plate support frame, the workpiece being sleeved on the top end of the support rod.

[0006] Preferably, the bottom end of the workpiece plate connecting ring is provided with a pair of feeding notches, and the pair of feeding notches are arranged opposite to each other.

[0007] Preferably, the auxiliary cutting mechanism includes a limiting ring fixedly installed at the top of the material plate support frame, a support frame fixedly connected to the top of the limiting ring, the support frame being sleeved on the outer wall of the material support rod, and a top cutting protrusion matching the material discharge notch being fixedly connected to the top of the support frame.

[0008] Preferably, the ejection mechanism includes an ejection groove formed at the top of the support rod, a spring seat is fixedly installed at the bottom of the ejection groove, and an ejection protrusion is fixedly connected to the top of the spring rod of the spring seat.

[0009] Preferably, a positioning rod is fixedly connected to the top of the base, and the positioning rod abuts against the bottom of the material plate support frame.

[0010] Preferably, the top-cutting protrusion is trapezoidal in shape, and a triangular cutting strip is fixedly connected to the top of the top-cutting protrusion.

[0011] Preferably, the bottom end of the material plate support frame is provided with a positioning groove that matches the positioning rod, and the depth of the positioning groove is the same as the thickness of the material plate connecting ring of the workpiece.

[0012] Preferably, the ejector bump is made of resin material, and the top dimension of the ejector bump is the same as the dimension of the ejector groove opening.

[0013] Beneficial effects:

[0014] 1. This utility model uses a top-cutting protrusion that matches the material feeding notch to fix the limiting ring. When the workpiece is pressed and moves towards the bottom of the support rod, the top-cutting protrusion can be inserted into the material feeding notch at the bottom of the workpiece material plate connecting ring. The pressure generated by the rotary cutting mechanism on the workpiece cuts the material feeding notch, causing the workpiece material plate connecting ring to break and expand, thereby separating the workpiece from the workpiece material plate connecting ring, improving the workpiece unloading effect, and thus improving the workpiece production efficiency.

[0015] 2. This utility model uses a spring seat fixedly connected to the bottom of the ejector groove to push the ejector protrusion to move without external pressure. The ejector protrusion pushes the workpiece to move along the support rod, and the workpiece is separated from the support rod for pre-ejection operation, which facilitates the improvement of the separation efficiency between the workpiece and the support rod.

[0022] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0024] Reference Figures 1-4 A material jamming mold structure includes a material plate support frame 1, with a base 2 at the bottom of the material plate support frame 1; a mold groove 8 is opened inside the material plate support frame 1, and an auxiliary cutting mechanism 4 is arranged inside the mold groove 8, which is used to cut the reserved groove of the material strip; a support rod 3 is arranged at the top of the material plate support frame 1, and a material ejection mechanism 9 is arranged at the top of the support rod 3, which is used to assist in material ejection; a workpiece 5 is arranged at the top of the material plate support frame 1, and the workpiece 5 is fastened to the top of the support rod 3.

[0025] The auxiliary cutting mechanism 4 inside the mold groove 8 can apply pressure to the workpiece 5 when the rotary cutting mechanism presses down and fastens to the outer wall of the workpiece 5. The pressure is used to cut the connecting ring of the material plate at the bottom of the workpiece 5. This can avoid the workpiece 5 being unable to separate from the material plate and getting stuck after the workpiece 5 is circumcised due to the pressure applied by the circumcised mechanism. The support rod 3 at the top of the material plate support frame 1 can be used to support the workpiece 5 so that the rotating device can circumcise the workpiece 5. The unloading mechanism 9 at the top of the support rod 3 can push the workpiece 5 after the rotary cutting equipment has separated from the workpiece 5, which facilitates the subsequent unloading operation of the workpiece 5.

[0026] like Figures 1-4 As shown, a pair of feeding notches 6 are provided at the bottom end of the material plate connecting ring of workpiece 5. The pair of feeding notches 6 are arranged opposite to each other. The auxiliary cutting mechanism 4 includes a support frame 10 fixedly installed on the top of the material plate support frame 1. A limiting ring 11 is fixedly connected to the top of the support frame 10. The limiting ring 11 is sleeved on the outer wall of the support rod 3. A top cutting protrusion 12 that matches the feeding notch 6 is fixedly connected to the top of the limiting ring 11. The top cutting protrusion 12 that matches the feeding notch 6 is fixed by the limiting ring 11. When workpiece 5 is pressed and moves towards the bottom end of the support rod 3, the top cutting protrusion 12 can be inserted into the feeding notch 6 at the bottom end of the material plate connecting ring of workpiece 5. The pressure is used to cut the feeding notch 6, causing the material plate connecting ring of workpiece 5 to break and expand, thereby causing workpiece 5 to separate from the material plate connecting ring of workpiece 5. This avoids the situation where workpiece 5 is squeezed by the rotary cutting equipment and stuck with the material plate connecting ring, making it difficult to remove the material.

[0027] like Figure 4 As shown, the ejection mechanism 9 includes an ejection groove 13 opened at the top of the support rod 3. A spring seat 14 is fixedly installed at the bottom of the ejection groove 13. An ejection protrusion 15 is fixedly connected to the top of the spring rod of the spring seat 14. Through the spring seat 14 fixedly connected to the bottom of the ejection groove 13, the ejection protrusion 15 can be pushed to move without external pressure. The ejection protrusion 15 is used to push the workpiece 5 to move along the support rod 3, and the workpiece 5 is separated from the support rod 3 for pre-ejection operation, which facilitates the improvement of the separation efficiency of the workpiece 5 from the support rod 3.

[0028] like Figures 1-3 As shown, a positioning rod 7 is fixedly connected to the top of the base 2. The positioning rod 7 abuts against the bottom of the material plate support frame 1. The positioning rod 7 fixedly connected to the top of the base 2 can limit the descent height of the material plate support frame 1, so as to avoid the material plate support frame 1 from falling too far and causing the cutting point to change.

[0029] like Figure 3 and Figure 4 As shown, the top cutting protrusion 12 is trapezoidal in shape, and a triangular cutting strip is fixedly connected to the top of the top cutting protrusion 12. The trapezoidal top cutting protrusion 12 can expand the blanking notch 6 at the bottom of the workpiece 5, and then, in conjunction with the triangular cutting strip fixedly connected to the top of the top cutting protrusion 12, cut the connecting ring of the bottom plate of the workpiece 5.

[0030] like Figure 2 and Figure 4 As shown, the bottom end of the material plate support frame 1 is provided with a positioning groove that matches the positioning rod 7, and the depth of the positioning groove is the same as the thickness of the material plate connecting ring of the workpiece 5. The positioning groove at the bottom end of the material plate support frame 1 can guide and position the positioning rod 7. At the same time, when the positioning rod 7 is fully inserted into the positioning groove, the limiting ring 11 will protrude from the horizontal plane of the material plate support frame 1. The cutting depth of the top cutting protrusion 12 can be adjusted by using the misalignment distance between the limiting ring 11 and the top end of the material plate support frame 1.

[0031] like Figure 4 As shown, the ejector protrusion 15 is made of resin material, and the top size of the ejector protrusion 15 is the same as the opening size of the ejector groove 13. This allows the ejector protrusion 15 to retract into the ejector groove 13 and fill the gap at the top of the ejector groove 13, thus preventing the workpiece 5 from deforming under pressure due to a gap at the top of the ejector groove 13.

[0032] The working principle of this utility model is as follows: The material plate support frame 1 is connected to the material support device of the veneer cutting equipment, and then the base 2 is connected to the bottom mold base of the veneer cutting equipment, so that the support rod 3 corresponds to the veneer cutting point of the veneer cutting equipment. When the veneer cutting equipment is running, the workpiece 5 is moved to the top of the material plate support frame 1. The bottom mold base of the veneer cutting equipment pushes the material plate support frame 1 upward, and the support rod 3 supports and positions the workpiece 5. Then, the veneer cutting mechanism of the veneer cutting equipment descends and applies pressure to the material plate support frame 1, so that the material plate support frame 1 and the positioning support rod 7 at the top of the base 2 are in contact with each other. Then, the veneer cutting cylinder of the veneer cutting equipment will wrap around the workpiece 5 on the outer wall of the support rod 3, and after pressing and positioning the workpiece 5, the veneer cutting operation is performed. During the pressing process of the veneer cutting equipment, the descending material plate support frame 1 will cause the limit The positioning ring 11 protrudes, and the top cutting protrusion 12 at the top of the positioning ring 11, under pressure, expands and cuts the material discharge notch 6 at the bottom of the workpiece 5. After the rotary cutting operation of the workpiece 5 is completed, the rotary cutting mechanism of the rotary cutting equipment disengages from the support rod 3 and the workpiece 5. The spring seat 14, which is fixedly connected to the bottom of the support rod 3, pushes the ejection protrusion 15 to move without external pressure. The ejection protrusion 15 pushes the workpiece 5 to move along the support rod 3, and performs a pre-ejection operation to remove the workpiece 5 from the support rod 3. When the rotary cutting equipment is run again, the bottom mold base and the material plate support frame 1 are reset in sequence to perform the ejection operation, so that the workpiece 5 is separated from the material plate. The whole device effectively avoids the situation where the workpiece 5 and the material plate are easily stuck and stuck together, thus improving the production efficiency of the equipment.

[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.
