Description

Technical Field

[0001] The utility model relates to the technical field of zirconia ceramic knife production, in particular to an injection molding device for zirconia ceramic knife production. Background Art

[0002] Zirconia ceramic knives are knives made by sintering nanoscale zirconia powder under high pressure and high temperature, with characteristics such as high hardness, high density, wear resistance, and non-metallic casting. They are mainly used for cutting non-hard foods such as vegetables, fruits, and meats, and are green environmental protection products in modern kitchens.

[0003] When producing zirconia ceramic knives, zirconia powder, additives, and stabilizers are put into a ball mill tank using ball milling and mixing, and mixed through methods such as vibration milling and adding glue to ensure the uniformity and consistency of the materials. Then, a 300-ton heavy press and secondary vacuum high-pressure forming technology are used to press the mixed ceramic powder into a knife blank, and finally, a sintering process is carried out. The above process has high requirements for the powder morphology, surface charge status, and granulation of the mixed powder, and the pressing process is difficult. When using pressing forming, it is difficult to ensure the uniformity of the materials inside the knife blank. To solve the above problems, we propose an injection molding device for zirconia ceramic knife production. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings in the prior art, and propose an injection molding device for zirconia ceramic knife production.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An injection molding device for zirconia ceramic knife production, including a zirconia ceramic knife injection molding machine. An extrusion barrel is installed on the left side of the zirconia ceramic knife injection molding machine, and a conveyor belt is arranged on the left side of the zirconia ceramic knife injection molding machine. A mold assembly is placed on the conveyor belt; the mold assembly includes an upper template and a lower template. A convex strip is fixedly installed on the upper template, and a groove matching the convex strip is correspondingly opened on the lower template. Half-knife mold grooves and half-feed through grooves are opened on both the upper template and the lower template. A feed half-barrel is fixedly installed on the side edges of the upper template and the lower template. A sliding gate is slidably installed on the upper template. A connecting side plate is fixedly installed on the side of the sliding gate, and a number of compression springs are fixedly connected between the connecting side plate and the upper side of the upper template.

[0007] Preferably, a feeding barrel is fixedly installed on the upper side of the zirconia ceramic knife injection molding machine, and the feeding barrel is connected to the inside of the zirconia ceramic knife injection molding machine.

[0008] Preferably, a controller is fixedly installed on the side of the zirconia ceramic knife injection molding machine.

[0009] Preferably, a support base plate is provided on the side of the conveyor belt. A first support and a second support are fixedly connected to the support base plate in sequence, and the second support is an L-shaped support.

[0010] Preferably, a first hydraulic rod is fixedly installed on the side of the first support. The center position of the first hydraulic rod is aligned with the extrusion barrel, and an electromagnet is installed on the output end of the first hydraulic rod.

[0011] Preferably, a second hydraulic rod is fixedly installed at the bottom of the second support, and an electromagnetic chuck is fixedly installed on the output end of the second hydraulic rod.

[0012] Preferably, a side pressing plate is fixedly connected to the side of the electromagnetic chuck.

[0013] Preferably, the upper template and the lower template are cast iron templates. The outer diameter of the feeding semi-cylinder is adapted to the inner diameter of the extrusion barrel, and the side of the sliding gate plate is in sliding contact with the inner side of the semi-feeding through groove.

[0014] Compared with the related art, an injection molding device for the production of zirconia ceramic knives proposed by the present utility model has the following beneficial effects:

[0015] In the present utility model, for the injection molding device for the production of zirconia ceramic knives, a zirconia ceramic knife injection molding machine is provided. A mold assembly is provided on the side of the extrusion barrel of the zirconia ceramic knife injection molding machine. In the mold assembly, the upper template and the lower template are used for mold closing. Both the upper template and the lower template are made of cast iron. Gravity mold closing is carried out by using the gravity of the cast iron material. A number of semi-tool mold grooves are provided on both the upper template and the lower template. When the mold is closed, complete tool mold grooves can be produced. Under the operation of the zirconia ceramic knife injection molding machine, cobalt oxide mixture is extruded from the extrusion barrel. The cobalt oxide mixture enters the feeding through groove from the feeding barrel formed by the mold closing of the feeding semi-cylinder, and then is filled into the tool mold grooves from the feeding through groove. When the filling of the tool mold grooves is completed, the feeding at the extrusion barrel stops. Subsequently, when the mold is opened, a knife blank is formed in the semi-tool mold grooves on the lower template. A number of knife blanks can be generated by one extrusion, and the processing efficiency is relatively high. In addition, the zirconia ceramic knife blank is generated by using the injection molding process. Before injection molding, the zirconia powder and the binder need to be mixed in a certain proportion to make the raw material have fluidity, so as to ensure the uniformity of the extruded zirconia material, and further make the internal material of the formed knife blank have better uniformity, make the strength of the knife blank higher, and improve the production quality of the zirconia ceramic knife.

Specific embodiments

[0022] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Refer to Figures 1-5 and, for reference, please also refer to Figures 1-5 , wherein Figure 1 Schematic three-dimensional structure of an injection molding device for the production of zirconia ceramic knives proposed by the present utility model Figure 1 ; Figure 2 Schematic three-dimensional structure of an injection molding device for the production of zirconia ceramic knives proposed by the present utility model Figure 2 ; Figure 3 Partial three-dimensional structure schematic diagram of an injection molding device for the production of zirconia ceramic knives proposed by the present utility model; Figure 4 Schematic three-dimensional disassembly of the mold assembly Figure 1 ; Figure 5 Schematic three-dimensional disassembly of the mold assembly Figure 2 。An injection molding device for the production of zirconia ceramic knives includes: a zirconia ceramic knife injection molding machine 1, an extrusion barrel 4 is installed on the left side of the zirconia ceramic knife injection molding machine 1, a conveyor belt 5 is arranged on the left side of the zirconia ceramic knife injection molding machine 1, and a mold assembly 6 is placed on the conveyor belt 5.

[0024] In this method, the mold assembly 6 includes an upper template 61 and a lower template 62. A rib 63 is fixedly installed on the upper template 61, and a groove 64 matching the rib 63 is correspondingly formed on the lower template 62. Half tool mold grooves 65 and half feed through grooves 66 are formed on both the upper template 61 and the lower template 62. A feed half cylinder 67 is fixedly installed on the side margins of the upper template 61 and the lower template 62. A sliding gate 68 is slidably installed on the upper template 61. A connecting side plate 69 is fixedly installed on the side of the sliding gate 68, and a plurality of compression springs 610 are fixedly connected between the connecting side plate 69 and the upper side surface of the upper template 61.

[0025] Through the above settings, with the rib 63 provided on the upper template 61 and the groove 64 matching the rib 63 correspondingly formed on the lower template 62, when the upper template 61 and the lower template 62 are closed, the rib 63 engages inside the groove 64, thus ensuring the sealing performance during mold closing.

[0026] In this method, a feeding cylinder 3 is fixedly installed on the upper side of the zirconia ceramic knife injection molding machine 1. The feeding cylinder 3 is communicated with the inside of the zirconia ceramic knife injection molding machine 1, and a controller 2 is fixedly installed on the side of the zirconia ceramic knife injection molding machine 1.

[0027] Through the above settings, the working states of the various electrical components in the present utility model can be controlled by the controller 2, improving the degree of automation.

[0028] In this method, a support bottom plate 7 is arranged on the side of the conveyor belt 5. A first support 8 and a second support 9 are fixedly connected in sequence on the support bottom plate 7. The second support 9 is an L-shaped support. A first hydraulic rod 10 is fixedly installed on the side of the first support 8. The central position of the first hydraulic rod 10 is aligned with the extrusion barrel 4. An electromagnet is installed on the output end of the first hydraulic rod 10. A second hydraulic rod 11 is fixedly installed at the bottom of the second support 9. An electromagnetic chuck 12 is fixedly installed on the output end of the second hydraulic rod 11. A side pressing plate 13 is fixedly connected to the side of the electromagnetic chuck 12.

[0029] Through the above settings, the conveyor belt 5 provides a conveying platform for the mold assembly 6. The central position of the first hydraulic rod 10 is aligned with the extrusion barrel 4. When the first hydraulic rod 10 drives and pushes the mold assembly 6 to approach the extrusion barrel 4, the driving force is not eccentric.

[0030] In this method, the upper template 61 and the lower template 62 are cast iron templates. The outer diameter of the feed half cylinder 67 is adapted to the inner diameter of the extrusion barrel 4. The side of the sliding gate 68 is in sliding contact with the inner side of the half feed through groove 66.

[0031] Through the above settings, with the upper template 61 and the lower template 62 being cast iron templates, due to the high quality of cast iron, the mold can be closed by the self-weight of the upper template 61 without adding vertical limiting measures.

[0032] The working principle of an injection molding device for the production of zirconia ceramic knives provided by the present utility model is as follows:

[0033] During use, zirconia powder and a binder are mixed in a certain proportion and added to the feeding cylinder, so that the flowable zirconia flows into the zirconia ceramic knife injection molding machine 1. Under the action of the zirconia ceramic knife injection molding machine 1, the material is extruded towards the extrusion cylinder 4, so that the fluid cobalt oxide in the extrusion cylinder 4 enters the feeding cylinder formed by the clamping of the feeding half cylinder 67 into the feeding through groove, and then fills the tool mold cavity from the feeding through groove. When the filling of the tool mold cavity is completed, the feeding at the extrusion cylinder 4 stops. Subsequently, the electromagnet on the output end of the first hydraulic rod 10 starts and the first hydraulic rod 10 retracts, pulling back the entire mold assembly 6, so that the feeding cylinder withdraws from the inside of the extrusion cylinder 4. Subsequently, the electromagnet is powered off, and the conveyor belt 5 starts to convey the mold assembly that has completed the injection to the lower part of the second bracket 9. When it is conveyed to the bottom of the second hydraulic rod 11, at this time, the unfilled mold assembly 6 on the conveyor belt 5 is exactly aligned with the extrusion cylinder 4. The conveyor belt 5 stops conveying, and the first hydraulic rod 10 extends to insert the feeding cylinder formed by clamping the end of the new mold assembly 6 into the extrusion cylinder 4. The zirconia ceramic knife injection molding machine 1 works for extrusion. At the same time, the second hydraulic rod 11 starts to drive the electromagnetic chuck 12 to press against the upper template 61. At this time, the side pressing plate 13 on the side of the electromagnetic chuck 12 presses the sliding gate 68 into the feeding through groove, so that the connection between the tool through groove and the feeding through groove is disconnected, and individual non - related knife blanks are formed in the tool mold cavity. Subsequently, the electromagnetic chuck 12 is started to adsorb the upper template 61 at the bottom, and the second hydraulic rod 11 is started to contract, thereby driving the upper template 61 to rise to complete the mold opening operation. At the same time, the sliding gate 68 on the upper template 61 slides upward and resets under the rebounding action of the compression spring 610, so that knife blanks are formed in the half - tool mold cavities 65 on the lower template 62. The injection and mold opening processes are synchronized throughout the process, and the relevant cooperation of each electrical component is controlled by the internal compilation program of the controller 2, with a high degree of automation and relatively high production efficiency.

[0034] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural or equivalent process transformation made by using the description and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be similarly included within the patent protection scope of the present utility model.
