Description

Technical Field

[0001] The present application relates to the technical field of tooling, and in particular to hot extrusion tooling for non-standard parts. Background Art

[0002] Since plastic materials can be processed by thermoplastic processing under certain temperature and pressure, this property makes plastic materials widely used in the manufacturing industry. At present, hot extrusion tooling is mainly fixed on the work surface. When one process is completed and the next process is carried out, it is usually necessary to manually flip the parts to the next station; because the workpieces that have just been hot extruded usually have a high temperature, workers need to wait for the parts to cool down before flipping them, which is not conducive to improving production efficiency. Summary of the invention

[0003] In view of this, the present application provides a non-standard hot extrusion tooling, which realizes the flipping of non-standard parts during the processing by setting a flipping mechanism, and specifically adopts the following technical solutions:

[0004] The hot extrusion tooling for non-standard parts comprises a base plate and a flipping mechanism, wherein a positioning plate is fixedly and sealedly connected above the base plate, and air passages for adsorbing non-standard parts are provided in the base plate and the positioning plate; the flipping mechanism comprises an active rod and a driven rod, wherein one end of the active rod and the driven rod are both rotatably connected to the connecting plate, and the other end is hinged to a connecting rod, and one end of the connecting rod hinged to the driven rod is rigidly connected to the base plate; the active rod is driven to rotate by a motor, and the base plate is flipped through the linkage of the connecting rod and the driven rod.

[0005] Preferably, two of the bottom plate and two of the flipping mechanisms are provided, and are symmetrically arranged on both sides of the connecting plate.

[0006] Further preferably, the active rods of the two flipping mechanisms are driven by the two motors respectively, or one motor drives one of the active rods, and the other active rod achieves synchronous rotation through a linkage structure between the two active rods.

[0007] In order to ensure the synchronous reverse flipping of the two bottom plates, the linkage structure between the two active rods is gear meshing.

[0008] Preferably, the driven rod and the base plate may be connected by a slot, a key or welding.

[0009] Preferably, a plurality of air guide grooves are provided on the positioning plate, and the air guide grooves are connected to the air passage.

[0010] Preferably, sealing rings are respectively provided at the air guide grooves at the innermost and outermost sides of the positioning plate.

[0011] The beneficial effects of the present application are as follows: the present application realizes the flipping of non-standard parts during the production process by setting up a flipping mechanism, thereby avoiding high temperature scalding workers at the source and shortening the flipping waiting time; at the same time, two flipping mechanisms capable of reverse synchronous flipping are set up to save the time of changing workstations for non-standard parts, improve operational efficiency and ensure the stability of the base plate during the flipping process.

[0016] The following will be combined with the drawings of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described in the present application are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0017] Combination Figure 1 to Figure 3 , the hot extrusion tooling for non-standard parts described in the present application is further described, including a base plate 1 and a flipping mechanism, the top of the base plate 1 is fixedly and sealedly connected to a positioning plate 2, and the base plate 1 and the positioning plate 2 are both provided with air passages 7 for adsorbing non-standard parts; the flipping mechanism includes an active rod 3 and a driven rod 4, one end of the active rod 3 and the driven rod 4 are both rotatably connected to a connecting plate 6, and the other end is hinged to a connecting rod 5, and one end of the connecting rod 5 and the driven rod 4 is rigidly connected to the base plate 1; the active rod 3 is driven by a motor to rotate, and the base plate 1 is driven to flip through the linkage of the connecting rod 5 and the driven rod 4.

[0018] In order to facilitate the flipping and clamping of non-standard parts after a process is completed, two of the base plate 1 and the flipping mechanism are provided, and are symmetrically arranged on both sides of the connecting plate 6; there are differences in the positioning structures on the two base plates 1: one is used to position the front side of the part to be processed, and the other is used to position the back side of the part to be processed.

[0019] The active rods 3 of the two flipping mechanisms may be driven by two motors respectively, or one motor may drive one of the active rods 3 , and the other active rod 3 may be synchronously rotated through a linkage structure between the two active rods 3 .

[0020] In this embodiment, in order to ensure the synchronous reverse flipping of the two bottom plates 1, the linkage structure between the two active rods 3 is gear meshing.

[0021] The driven rod 4 and the base plate 1 may be connected by a slot, a key or by welding.

[0022] The positioning plate 2 is provided with a plurality of air guide grooves 8 , which are connected to the air passage 7 , thereby reducing the contact area between the positioning plate 2 and the non-standard parts, so that more gas can be sucked into the air passage 7 through the air guide grooves 8 , thereby improving the air suction efficiency.

[0023] It should be noted that sealing rings (not shown) are respectively provided at the innermost and outermost circles of the air guide grooves 8 of the positioning plate 2 to ensure sealing when adsorbing non-standard parts.

[0024] Principle of use: The non-standard parts are a whole plate before hot extrusion; first install and position the whole plate on the positioning plate 2, then use an external negative pressure device for adsorption, then use the mold to hot extrude the whole plate and divide it into separate semi-finished non-standard parts; then the motor drives the active rod 3 to rotate, and the connecting rod 5 and the driven rod 4 are linked to make the bottom plate 1 flip; at the same time, the gear structure at the driving end of the active rod 3 can drive another flipping mechanism to make the two bottom plates 1 flip synchronously until they are close to each other and parallel, at this time the negative pressure of the adsorbed semi-finished product gradually reduces the negative pressure, and the negative pressure of the negative pressure device connected to the other positioning plate gradually increases the negative pressure to adsorb the completed side of the semi-finished product; then the motor reverses to make the two bottom plates 1 flip each other open, and the adsorbed semi-finished products are hot extruded by the mold, and finally the non-standard parts are formed.
