Description

Technical Field

[0001] The utility model relates to precision manufacturing, in particular to injection molding technology, and specifically, is a high-quality injection molding mold for filling and pressurizing. Background Art

[0002] See also Figure 1 The product 100 comprises a middle connecting sleeve 101, wherein both ends of the middle connecting sleeve 101 are respectively provided with a bottle mouth connecting sleeve 102 and a medicine outlet connecting sleeve 103, and the medicine outlet connecting sleeve 103 is a long thin-walled sleeve body with a tapered shape.

[0003] Since the medicine outlet connecting sleeve 103 is a tapered long thin-walled sleeve, the current molding method uses molten raw material injection molding at the corresponding cavity of the middle connecting sleeve 101. When the injection pressure is insufficient, the molding quality of the medicine outlet connecting sleeve 103 cannot be well guaranteed.

[0004] Therefore, it is necessary to provide a high-quality injection molding mold for filling and pressurizing to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a high-quality injection molding die for filling and pressurizing.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] A high-quality injection molding die for filling and pressurizing, comprising an upper die and a lower die that are arranged accordingly;

[0008] The upper mold is provided with an upper mold cavity, and correspondingly, the lower mold is provided with a lower mold cavity, the lower mold cavity is provided with a lower mold insert, and the lower mold is provided with a molten raw material inlet, the molten raw material inlet is connected to the upper mold cavity through an injection port, and an auxiliary punching pressurizing component is provided on the lower mold;

[0009] The auxiliary punching pressurizing component comprises a pressurizing channel opened below the inlet of the molten raw material, and a pressurizing lifting column is arranged in the pressurizing channel.

[0010] Furthermore, a lower mold insert lifting sleeve is correspondingly provided in the lower mold cavity.

[0011] Furthermore, the upper mold cavity has an upper mold lower cavity and an upper mold upper cavity that match the middle connecting sleeve and the medicine outlet connecting sleeve.

[0012] Furthermore, the injection port is connected to the upper mold and the lower cavity.

[0013] Furthermore, the injection port is connected to the upper mold and the lower cavity at two-thirds or three-quarters of the height.

[0014] Furthermore, the injection port is in a tapered inverted trumpet shape.

[0015] Furthermore, a molten raw material inlet is connected to two symmetrical upper mold cavities through the injection port.

[0016] Compared with the prior art, the utility model adopts an auxiliary punching pressurization method. During injection molding, the pressurization is performed by raising the pressurization lifting column to ensure the injection molding pressure and thus ensure the molding quality.
