Description

Technical Field

[0001] The present invention belongs to the technical field of basic non-cutting machining or treatment of metal plates, tubes, rods or profiles, and particularly relates to a demoulding device, and more particularly to a demoulding device for a special-shaped copper busbar diversion die and its working method. Background Art

[0002] The diversion die, also known as the front chamber die, is a key die type in the industrial profile extrusion process.

[0003] The diversion die is usually used for the forming of aluminum profiles. When it is used for the extrusion forming of copper metal, the die is designed as a split die, and the die is opened by the way of pulling apart the die.

[0004] Due to the strong binding force and high ductility between copper atoms, copper metal is prone to adhesion to the die surface. Especially in the diversion cavity (front chamber) and the transition area of the cavity of the diversion die, the metal flow path is complex, and copper materials will stay to form microscopic welding (cold welding), significantly increasing the demoulding resistance. If the direct pulling-apart die-opening method is adopted, some copper materials will remain on the die surface due to the adhesion between the copper materials and the die, resulting in product damage.

[0005] Therefore, how to solve the technical problem that the product is damaged by the pulling-apart die-opening method is an urgent problem to be solved by those skilled in the art.

[0006] It should be noted that the above information disclosed in this background art part is only used to understand the background art of the concept of this application. Therefore, the above description is not considered as information of the prior art. Summary of the Invention

[0009] Specifically, the demolding mechanism further includes: a first mounting plate and a plurality of linkage components; the first mounting plate is sleeved on the transverse movement component, and each of the linkage components is penetrated through the first mounting plate; the demolding inclined plate is arranged at the lower part of the first mounting plate, and the upper hinged end of the inclined surface of the demolding inclined plate is hinged to the first mounting plate; the downward pressing component is adapted to drive the transverse movement component and the first mounting plate to move downward as a whole; the transverse movement component is adapted to drive the two first mounting plates to move away from each other, and at the same time, the linkage components are forced to move downward to push the demolding inclined plate to rotate, that is, to adjust the inclination angle of the inclined surface.

[0011] Specifically, the downward pressing component includes: a lower pressing plate and a first driving member; the first driving member is arranged on the bracket; the upper surface of the lower pressing plate is connected to the first driving member, the lower surface is connected to the transverse movement component, and an inclined groove for accommodating the ball is formed on the lower surface; the first driving member is adapted to drive the lower pressing plate to move downward, so that the transverse movement component and the first mounting plate move downward as a whole; wherein, during the transverse movement of the first mounting plate, the inclined groove is adapted to guide the ball to move downward to make the demolding inclined plate rotate.

[0012] Specifically, the transverse movement component includes: a lead screw and a pair of second mounting plates; the second mounting plates are connected to the lower surface of the lower pressing plate; both ends of the lead screw are respectively penetrated through the corresponding second mounting plates, and one end thereof is connected with a second driving member; the two first mounting plates are both penetrated through the lead screw; the second driving member is adapted to drive the lead screw to rotate so that the two first mounting plates move away from each other.

[0013] Specifically, each of the transmission rods is arranged along the length direction of the demolding inclined plate.

Specific implementation manners

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0025] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. In addition, in the drawings, for the effective description of the technical content, the thickness of the components may be exaggerated or reduced.

[0026] Below, with reference to the accompanying drawings, some embodiments of the present invention will be described in detail. Without conflict, the following embodiments and the features in the embodiments may be combined with each other.

[0027] As Figure 1 shown, at least one embodiment provides a demolding device for a special - shaped copper - bar flow - guiding die, including: a bracket 1, a cross - translation assembly 3, a press - down assembly 4, and a pair of demolding mechanisms 2.

[0028] In some embodiments, a placement position 11 for placing the flow - guiding die 5 is provided on the bracket 1.

[0029] In some embodiments, the flow - guiding die 5 is formed by combining a left template and a right template, and a pouring port 51 is formed on the upper surface. Molten copper is poured into the die through the pouring port 51 to form a copper bar.

[0030] As Figure 2As shown, in some embodiments, the pressing assembly 4 is disposed on the bracket 1 and is located above the placement position 11; wherein the pressing assembly 4 includes: a pressing plate 41 and a first driving member 42, and the pressing plate 41 is driven to rise and fall by the first driving member 42.

[0031] In this embodiment, the first driving member 42 may be, but is not limited to, a cylinder.

[0032] In some embodiments, the transverse movement assembly 3 is disposed on the lower pressing plate 41 to follow the lifting and lowering of the lower pressing plate 41 .

[0033] In some embodiments, a pair of demoulding mechanisms 2 are both arranged on the transverse moving assembly 3 , so as to rise and fall along with the transverse moving assembly 3 . At the same time, the two demoulding mechanisms 2 can be driven by the transverse moving assembly 3 to move back to back or face to face.

[0034] like Figure 3 As shown, in some embodiments, the demoulding mechanism 2 includes: a demoulding inclined plate 21.

[0035] Specifically, the demoulding inclined plate 21 is extended into the pouring port 51 of the guide mold 5 by lowering the lower pressure plate 41, and the inclined surface of the demoulding inclined plate 21 is against the pouring port 51; then, the two demoulding inclined plates 21 are moved back to back by the drive of the transverse movement component 3, so that the two demoulding inclined plates 21 pull the guide mold 5 apart.

[0036] In this embodiment, the demoulding inclined plate 21 is set at an angle, so as to generate a vertical force during the initial demoulding, thereby causing the guide mold 5 to produce a slight vertical displacement. This part of the vertical shear force is used to destroy the bonding force between the copper busbar and the guide mold 5, thereby facilitating the separation of the guide mold 5.

[0037] like Figure 4 As shown, in some embodiments, the demolding mechanism 2 further includes: a first mounting plate 22 and a plurality of linkage components 23; wherein, the first mounting plate 22 is sleeved on the transverse movement component 3, and each linkage component 23 is passed through the first mounting plate 22, and the demolding inclined plate 21 is arranged at the lower part of the first mounting plate 22, and the upper hinged end 211 of the inclined surface of the demolding inclined plate 21 is hinged to the first mounting plate 22.

[0038] Specifically, the first mounting plate 22 can follow the transverse movement assembly 3 to rise and fall, and can be moved by the transverse movement assembly 3; Figure 5 As shown, when the two first mounting plates 22 move away from each other, the linkage assembly 23 will be forced to move downward, thereby pushing the demoulding inclined plate 21 to rotate, that is, the inclination angle of the inclined surface of the demoulding inclined plate 21 will gradually tend to vertical, thereby eliminating the vertical force component.

[0039] In this embodiment, after the mold is separated, the demolding inclined plate 21 becomes vertical. At this time, the vertical shear force is avoided from continuing to be generated, so that the mold moves completely in the horizontal direction. Even if the relative sliding direction of the copper bar and the mold is strictly along the demolding axis, the non-directional scratches caused by the lateral sliding in the inclined plane stage are avoided.

[0040] In some embodiments, optionally, a coil spring is provided at the upper hinge end 211; the presence of the coil spring causes the demolding inclined plate 21 to be subjected to a force for reset rotation, that is, when the two first mounting plates 22 move away from each other, the demolding inclined plate 21 is always in contact with the linkage assembly 23.

[0041] In some embodiments, the linkage assembly 23 includes: a ball 231 and a transmission rod 232.

[0042] Specifically, the transmission rod 232 is inserted through the first mounting plate 22, and the lower end surface abuts against the demolding inclined plate 21; the ball 231 is arranged on the upper end surface of the transmission rod 232 and protrudes from the first mounting plate 22.

[0043] In this embodiment, during the transverse movement of the first mounting plate 22, the ball 231 is forced to press down, thereby pushing the transmission rod 232 to descend, that is, pushing the demolding inclined plate 21 to rotate.

[0044] As Figure 5 shown, in some embodiments, the upper surface of the lower pressing plate 41 is connected to the first driving member 42, the lower surface is connected to the transverse movement assembly 3, and an inclined groove 411 for accommodating the ball 231 is formed on the lower surface.

[0045] In this embodiment, as Figure 4 shown, before the first mounting plates 22 move away from each other, the ball 231 is located at the deepest part of the inclined groove 411. At this time, the inclination angle of the inclined surface of the demolding inclined plate 21 is the largest; as Figure 5 shown, when the first mounting plates 22 move away from each other, the ball 231 gradually moves out of the inclined groove 411. During this process, the ball 231 descends relative to the first mounting plate 22, that is, the ball 231 pushes the demolding inclined plate 21 to rotate through the transmission rod 232 to change the inclination angle of the inclined surface of the demolding inclined plate 21.

[0046] As Figure 2 shown, in some embodiments, the transverse movement assembly 3 includes: a lead screw 31 and a pair of second mounting plates 32; specifically, the second mounting plates 32 are connected to the lower surface of the lower pressing plate 41, and both ends of the lead screw 31 are respectively inserted through the corresponding second mounting plates 32, and one end thereof is connected to a second driving member 33.

[0047] In this embodiment, both of the two first mounting plates 22 are sleeved on the lead screw 31. The lead screw 31 is driven to rotate by the second driving member 33, so that the two first mounting plates 22 move away from each other or face each other; wherein, the second driving member 33 may but is not limited to be a hand wheel.

[0048] As Figure 5 shown, in some embodiments, a first thread section 311 and a second thread section 312 with opposite thread directions are provided on the lead screw 31, and the two first mounting plates 22 are respectively arranged on the first thread section 311 and the second thread section 312.

[0049] In this embodiment, the upper surface of the first mounting plate 22 is attached to the lower surface of the lower pressing plate 41; when the lead screw 31 rotates in one direction, since the thread directions of the first thread section 311 and the second thread section 312 are opposite, the two first mounting plates 22 will move in opposite directions, that is, move away from each other or face each other.

[0050] At least one embodiment also provides a working method of a demolding device for a special-shaped copper bar diversion mold, including: driving the transverse movement assembly 3 and the two demolding mechanisms 2 to move downward integrally through the downward pressing assembly 4; making the demolding inclined plate 21 in the demolding mechanism 2 extend into the diversion mold 5 through the downward movement of the demolding mechanism 2; driving the two demolding mechanisms 2 to move away from each other through the transverse movement assembly 3, so as to separate the two demolding inclined plates 21 from the diversion mold 5; wherein the inclination angle of the inclined surface is adjusted during the transverse movement of the demolding inclined plate 21 to eliminate the vertical component force.

[0051] In some embodiments, during the process of the two demolding mechanisms 2 moving away from each other, the demolding inclined plate 21 is driven to rotate by the linkage assembly 23 in the demolding mechanism 2 to adjust the inclination angle of the inclined surface.

[0052] In some embodiments, the linkage assembly 23 in the demolding mechanism 2 is guided to move downward through the inclined groove 411 on the lower pressing plate 41 of the downward pressing assembly 4, so that the demolding inclined plate 21 is forced to rotate.

[0053] For the specific structure and implementation process of the demolding device for the special-shaped copper bar diversion mold, refer to the relevant discussions in the above embodiments, and will not be elaborated here.

[0054] To sum up, the demolding device for the special-shaped copper bar diversion mold and its working method are provided with a rotatable demolding inclined plate 21, so that during the initial demolding, a vertical force is generated by the inclination of the demolding inclined plate 21, and then a slight displacement in the vertical direction is generated on the mold, and the vertical shear force is used to break the bonding force between the copper bar and the mold, facilitating the separation of the mold, and after demolding, the vertical direction is avoided by the vertical of the demolding inclined plate 21 to continue generating the vertical shear force, so that the mold moves completely in the horizontal direction, that is, the relative sliding direction between the copper bar and the mold is strictly along the demolding axis, avoiding non-directional scratches caused by lateral sliding in the inclined surface stage.
