Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vertical injection molding machines, in particular to a vertical injection molding machine. BACKGROUND

[0002] A vertical injection molding machine is an industrial mechanical device used for manufacturing plastic products. It is commonly used to inject molten plastic into a mold to produce plastic products of various shapes and sizes. According to the injection system of the vertical injection molding machine, it is generally divided into three main forms of vertical injection molding machines: plunger type, screw type, and screw-plunger injection type.

[0003] The existing Chinese patent application with the application publication number CN118181640A discloses a vertical injection molding machine, which includes a support seat with a through slot, two groups of lower molds with ejection assemblies and first springs at the bottom, a lower mold alternating movement mechanism on the support seat for alternating forward and backward movement of the two groups of lower molds, an upper mold and injection assembly on the rear side of the upper end of the support seat, a lifting mechanism on the rear side of the upper end surface of the support seat for driving the upper mold and injection mechanism to move up and down, and a top block above the support seat. When the lifting mechanism drives the upper mold to move downward, the top block drives the ejection assembly to move upward, and the injection part in the lower mold moves to the front side of the lower mold.

[0004] However, the vertical injection molding machine has the following defects in specific use:

[0005] 1. When the existing vertical injection molding machine injects injection material into the mold through the plunger and performs product injection in the mold, the injection material is heated and softened in the storage tank. Some heated injection material will adhere to the output port of the storage tank, causing waste when injecting injection material into the mold each time. At the same time, the injection material adhering to the inner wall of the storage tank near the mold and away from the heating system is prone to solidification during product injection, which may cause blockage of the output port of the storage tank and other problems.

[0006] 2. When the existing vertical injection molding machine transports injection material to complete product injection, the injection material is generally poured into the inside of the storage tank through a belt or other equipment. At this time, a large amount of injection material is poured into the inside of the storage tank at one time and subjected to heating and softening. The injection material away from the heating module (located in the middle part of the storage tank) may be difficult to heat completely or may not be heated, which affects the quality of the product after injection.
