Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figure 1 - Figure 4 As shown, the present invention is a mold for plastic products with a flash prevention function, including a lower mold assembly 1. Labor-saving demolding assemblies 2 are installed on the top sides of the lower mold assembly 1, an upper mold assembly 3 is installed on its top, and an auxiliary moving assembly 4 is installed on one side thereof.

[0027] By installing a labor-saving demolding assembly 2 on the device, when using this device, through this assembly, after injection molding is completed, when taking the mold or when overhauling the internal parts, it can provide a boosting effect, so that there is no need for labor to work time-consuming and laborious, greatly improving work efficiency.

[0028] The lower mold assembly 1 includes a bottom mold 101. Side plates 102 are installed on both sides of the bottom mold 101, an air pump mounting bracket 103 is installed in the middle thereof, an air pump body 104 is installed on the top of the air pump mounting bracket 103, a push column 105 is installed on the top of the air pump body 104, a mold block 106 is installed on the top of the push column 105, and a contracting outer column 107 is installed around it.

[0029] The labor-saving demolding assembly 2 includes a braking motor 201. The braking motor 201 is installed on both sides of the top of the side plate 102, and a push rod 202 is installed on its top. A connecting component 203 is installed on the top of the push rod 202. The connecting component 203 is installed on the bottom periphery of the top mold 301. Due to the low working efficiency of the internal working column 304 and the retractable outer column 107, at this time, the labor-saving demolding assembly 2 installed on the periphery can be used for labor-saving and boosting lifting and supporting work. The braking motor 201 inside drives the push rod 202 on its top to rise, and then the connecting component 203 on the top of the push rod 202 further drives and supports the work.

[0030] The upper mold assembly 3 includes a top mold 301. A wrapping block 302 is installed in the middle of the bottom of the top mold 301, and a feeding port 303 is installed in the middle of its top. The periphery of the wrapping block 302 is installed with a telescopic column 304. The telescopic column 304 is installed inside the retractable outer column 107. After the material is put in through the feeding port 303 on its top, under the action of the air pump main body 104, the push column 105 on its top is pushed upward, and then a pressing work is formed between the mold block 106 on its top and the wrapping block 302. At the same time, the telescopic column 304 inside the retractable outer column 107 on the side will contract, so that the pressing and injection molding work can be realized. Through the upward pressing, the occurrence of flash can be avoided.

[0031] The auxiliary moving assembly 4 includes a boosting pull ring 401 and a positioning ring 403. A threaded rod 402 is installed inside the boosting pull ring 401. The threaded rod 402 is installed on one side of the bottom mold 101. The positioning ring 403 is installed on the other side of the bottom mold 101 and is adjacent to the position of the threaded rod 402.

[0032] The connecting component 203 includes a mounting side plate 2031. A connecting end 2032 is installed in the middle of the mounting side plate 2031. The connecting end 2032 is installed on both sides of the bottom of the top mold 301, and is installed at the middle position of the mounting side plate 2031 through a fixing rod 2033. By removing the fixing rod 2033 of the push rod 202, the push rod 202 can be removed, and then the replacement work can be completed. After that, the two sides of the connecting end 2032 installed at the end of the new push rod 202 are installed, and then the fixing can be restored through the fixing rod 2033 to complete the replacement work.

[0033] When using this device, first install the upper mold assembly 3 on the top of the lower mold assembly 1 to complete the assembly work. Then, when in use, after putting the material through the feeding port 303 at its top, under the action of the air pump main body 104, the push column 105 at its top is pushed upward, and then a pressing work is formed between the mold block 106 at its top and the wrapping block 302. At the same time, the telescopic column 304 inside the retractable outer column 107 on hand will perform a retraction work, so that the pressing and injection molding work can be realized. Through the upward pressing, the occurrence of flash can be avoided. And after the work is completed, when it is necessary to remove the mold, or when it is necessary to disassemble the two mold assemblies, at this time, due to the low working efficiency of the internal working column 304 and the retractable outer column 107, the labor-saving mold removal assembly 2 installed around can be used for labor-saving and boosting lifting and supporting work. The brake motor 201 inside drives the push rod 202 at its top to rise, and then the connecting component 203 at the top of the push rod 202 further drives and supports the work. And if the middle push rod 202 is damaged, at this time, the push rod 202 can be removed by removing the fixing rod 2033, and then the removal work of the push rod 202 can be completed. After that, install the two sides of the connection end 2032 installed at the end of the new push rod 202, and then restore the fixation through the fixing rod 2033 to complete the replacement work.
