Description

Technical Field

[0001] The utility model belongs to the technical field of positioning auxiliary devices, in particular to a positioning auxiliary device for injection molding. Background Art

[0002] Injection molding is a method of producing industrial products. The sprue refers to the junction of the frame and the parts formed when the factory casts the model. It means the inlet and outlet for the flow of heated liquid materials. After injection molding, the sprue part needs to be separated from the molded product. Ultrasonic desprue is an efficient and environmentally friendly technology that uses ultrasonic vibration to remove the sprue of plastic parts. It transfers ultrasonic vibration energy to the sprue to separate the sprue from the plastic part, thereby achieving the purpose of removing the sprue.

[0003] At present, when using ultrasound to separate the sprue of an injection mold, the small-sized injection molded parts fall off and scatter on the workbench after ultrasonic vibration, making it inconvenient to collect the injection molded parts. Utility Model Content

[0004] The purpose of the utility model is to solve the above-mentioned problems and to provide a positioning auxiliary device for injection molding.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solution: a positioning auxiliary device for injection molding, comprising:

[0006] A positioning base, which is used for mounting on a workbench;

[0007] The enclosure has a positioning hole in its middle, the positioning hole is sleeved on the positioning base, and the top surface of the enclosure is shelled to form a collecting groove;

[0008] A positioning member is fixedly mounted on the top of the positioning base, a guiding slope is arranged on the edge of the positioning member, and a plurality of supporting bars are arranged on the top of the positioning member.

[0009] As a further description of the above technical solution:

[0010] The guiding slope is located above the first end of the enclosure member.

[0011] As a further description of the above technical solution:

[0012] The second end of the enclosure member extends to above the positioning member.

[0013] As a further description of the above technical solution:

[0014] A plurality of positioning grooves are formed on the top surface of the support bar.

[0015] As a further description of the above technical solution:

[0016] The bottom surface of the collecting tank is paved with a shock-absorbing layer.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0018] In the utility model, a positioning base is installed on a workbench, a positioning piece is installed on the positioning base, and a tooling connected to an ultrasonic modulator acts to place an injection molded piece on the positioning piece. After being vibrated at a high frequency, the injection molded piece is separated from the water outlet and enters a collecting tank along a guide inclined surface for collection, thereby avoiding the injection molded pieces from being scattered on the workbench and making it easy to collect the injection molded pieces.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-3 The utility model provides a technical solution: a positioning auxiliary device for injection molding, comprising:

[0026] A positioning base 1, which is used to be installed on a workbench;

[0027] The enclosure member 2 has a positioning hole 3 in the middle, and the positioning hole 3 is sleeved on the positioning base 1. The top surface of the enclosure member 2 is shelled to form a collecting groove 4;

[0028] A positioning member 5, which is fixedly mounted on the top of the positioning base 1, wherein the edge of the positioning member 5 is provided with a guide slope 6, and the top of the positioning member 5 is provided with a plurality of support bars 7;

[0029] The guide slope 6 is located above the first end 8 of the enclosure 2, ensuring that the injection molded parts separated by vibration on the positioning member 5 can smoothly slide along the guide slope 6 into the collecting tank 4;

[0030] The second end 9 of the enclosure 2 extends to the top of the positioning member 5 to prevent the injection molded part from splashing into the external space during vibration;

[0031] The top surface of the support bar 7 is provided with a plurality of positioning grooves 10, which are convenient for positioning the connection parts of the injection molded parts produced in one mold;

[0032] The bottom surface of the collecting tank 4 is paved with a shock-absorbing layer 11, which protects the injection molded parts and reduces the noise generated when the injection molded parts fall.

[0033] Working principle: First, install the positioning base 1 on the workbench, put the positioning hole 3 on the enclosure 2 on the positioning base 1, install the positioning member 5 on the positioning base 1, and keep the guide slope 6 on the positioning member 5 above the first end 8. Secondly, lay the shock-absorbing layer 11 in the collecting tank 4. Then, the extra connection part of the injection-molded part of one mold is placed on the support bar 7, and partially inserted into the positioning groove 10. The injection-molded part placed on the positioning member 5 by the tooling connected to the ultrasonic modulator is vibrated at high frequency and separated from the water outlet and enters the collecting tank 4 along the guide slope 6 for collection. The shock-absorbing layer 11 protects the injection-molded part and reduces the noise generated when the injection-molded part falls. During the process, the second end 9 protects the splash of the injection-molded part. Finally, remove the enclosure 2 as a whole and unload the injection-molded part in the collecting tank 4.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
