[0002] Molds are various molds and tools used in industrial production to obtain the desired products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, molds are tools used to make molded objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material. In the process of stamping parts manufacturing, molds are needed to stamp and shape the shape of the stamping parts.

[0003] In a demoulding auxiliary device for a mold with the public specification of Chinese utility model patent application CN218925852U, after the stamping of the stamping parts is completed, the processing personnel can drive the rotating rod to rotate by turning the hand turntable, thereby driving the vertical bevel gear to rotate, and the vertical bevel gear drives the transverse bevel gear to rotate. Since the transverse bevel gear is fixedly connected to the threaded rod, the transverse bevel gear can drive the threaded rod to rotate, thereby changing the vertical height of the lifting plate, pushing the bottom force plate to move upward, and withdrawing the stamped stamping parts from the mold to complete the rapid demoulding of the stamping parts. However, when it is used, the demoulding step needs to be operated by manpower, so that the demoulding process needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0020] 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 in 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.

[0021] See also Figure 1-Figure 4 As shown, a technical solution provided by the utility model:

[0022] A demoulding auxiliary device for a mold comprises a machine body 1, a support rod 2 is fixedly arranged at the bottom end of the machine body 1, a lower mold 3 is movably arranged on the outer side of the top end of the support rod 2 through a movable hole, a fixing groove 4 is opened at the bottom end of the lower mold 3, a bottom plate 5 is fixedly arranged inside the fixing groove 4 at the top end of the support rod 2, a hydraulic cylinder 6 is installed at the top end of the machine body 1, an upper mold 7 is fixedly arranged at the telescopic shaft end of the hydraulic cylinder 6, a support plate 8 is fixedly arranged at the top end of the outer side of the upper mold 7, a separation mechanism is arranged between the bottom end of the outer side of the upper mold 7 and the support plate 8, and an adjustment mechanism is arranged between the two sides of the machine body 1 and the lower mold 3;

[0023] Through the above scheme, the use of the mold can be realized, and the work of taking out the injection molded product separately can be completed, thereby assisting the demoulding work of the injection molded product;

[0024] The separation mechanism includes a pressing plate 9 and a spring 10. The pressing plate 9 is sleeved on the bottom end of the outer side of the upper mold 7. A plurality of springs 10 are evenly arranged on the bottom of the support plate 8. The bottom ends of the plurality of springs 10 are connected to the pressing plate 9.

[0025] Through the above scheme, by using the separation mechanism, when the upper mold 7 is withdrawn by the hydraulic cylinder 6, the pressure plate 9 loses the resistance of the lower mold 3, and the force of the spring 10 will be applied to the injection molded product, so that the injection molded product can be prevented from being moved by the action of the hydraulic cylinder 6 due to a certain adhesion connection with the upper mold 7 and remaining on the bottom plate 5. Since the contact area between the pressure plate 9 and the injection molded product is small, the injection molded product is not easy to be adhered to the pressure plate 9, so that the injection molded product is taken out from the lower mold 3;

[0026] The adjusting mechanism includes a threaded rod 11, a slide rod 12 and a connecting block 13. The threaded rod 11 is movably arranged on one side of the body 1 through a rotating shaft, the slide rod 12 is fixedly arranged on one side of the body 1 away from the threaded rod 11, and the connecting blocks 13 are fixedly arranged on both sides of the lower mold 3. The connecting blocks 13 are movably connected to the threaded rod 11 and the slide rod 12 through threaded holes and mounting holes respectively.

[0027] Through the above solution, the lower mold 3 can be moved up and down by using the adjustment mechanism, thereby achieving position adjustment of the lower mold 3;

[0028] An annular groove 14 is provided inside the pressing plate 9;

[0029] Through the above solution, the annular groove 14 is used to accommodate the limit block 15 and cooperate with the limit block 15 for use;

[0030] Limiting blocks 15 are fixedly arranged at the bottom ends of both sides of the upper mold 7 in the annular groove 14;

[0031] Through the above solution, the use of the limit block 15 in conjunction with the annular groove 14 can prevent the pressing plate 9 from being separated from the upper die 7 under the action of the spring 10, thereby ensuring the normal use of the separation mechanism;

[0032] A motor 16 is installed at one end of the top of the body 1 through a mounting seat, and the output shaft end of the motor 16 is transmission-connected to the rotating shaft where the threaded rod 11 is located through a coupling;

[0033] Through the above solution, the threaded rod 11 can be driven to rotate by using the motor 16.

[0034] When a demoulding auxiliary device for a mold of this embodiment is in use, the hydraulic cylinder 6 is activated to drive the upper mold 7 to move downward, so that the upper mold 7 and the lower mold 3 are close to each other for injection molding, and the edge of the pressing plate 9 is fitted with the edge of the lower mold 3. In order to better use the pressing plate 9 and the upper mold 7, an opening needs to be reserved at the top edge of the lower mold 3 to carry the pressing plate 9 and ensure the moving position of the pressing plate 9. After the injection molding is completed, the threaded rod 11 is driven to rotate by the activation of the motor 16, and the lower mold 3 can be moved downward with the rotation of the threaded rod 11 through the connection setting of the sliding rod 12. As the lower mold 3 moves The finished injection molded product will remain between the bottom plate 5 and the upper mold 7, thereby realizing the demoulding operation, and then the upper mold 7 is removed by using the hydraulic cylinder 6. In this process, because the pressure plate 9 loses the resistance of the lower mold 3, the spring 10 will apply force to the finished injection molded product, thereby preventing the finished injection molded product from moving with the action of the hydraulic cylinder 6 due to a certain adhesion connection with the upper mold 7 and remaining on the bottom plate 5. Since the contact area between the pressure plate 9 and the finished injection molded product is small, it is not easy for the finished injection molded product to be adhered to the pressure plate 9, thereby taking the finished injection molded product out of the lower mold 3, and realizing the demoulding of the finished injection molded product.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
