Horizontal injection press

Abstract

The invention discloses a horizontal injection press which comprises a working table, an injection molding mechanism, a fixed pressing plate, a movable pressing plate, a formwork plate, a horizontal driving mechanism, a guide rail and a plurality of guide columns; the movable pressing plate and the formwork plate slide in the extending direction of the guide columns, and the horizontal driving mechanism comprises a sliding table, a first transmission belt, a second transmission belt, a first connecting rod, a second connecting rod, a first main shaft nut, a second main shaft nut, a first driven belt wheel, a bearing plate, at least one driving motor, a driving sliding wheel, a first main shaft with an external thread and a second main shaft with an external thread; and the bearing plate and the driving motor are fixedly arranged on the working table, and the sliding table is arranged on the guide rail in a horizontally-sliding manner. The horizontal injection press is simple in structure and low in cost, the die opening and closing accuracy is high, multiple dies can be subject to injection molding through one-time injection molding operation, the injection molding efficiency is high, and the injection molding quality is good.

Description

technical field [0001] The invention relates to the field of injection molding machines, in particular to a horizontal injection molding machine. Background technique [0002] In the production process of steel structure products, plastic castings such as plastic handles and buttons will be used, and plastic castings need to be injected by injection molding machines. Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. It is divided into vertical, horizontal, and all-electric types. The horizontal injection molding machine has a short body and is easy to operate and maintain; the center of gravity of the machine is low and the installation is relatively stable; after the product is ejected, it can automatically fall by gravity, which is easy to realize fully automatic operation, so it is fav...

AI Technical Summary

Problems solved by technology

In the existing horizontal injection molding machine, the first half-mold and the second half-mold of the mold body are respectively fixed on the moving plate and the fixed plate, and the mold body is molded by moving the moving plate to carry out injection molding. However, the injection molding process in this way In one injection molding operation, only one mold body can be injected, and the injection molding efficiency is quite low

The movement of the moving plate is driven by the driving mechanism, which drives the moving plate and moves horizontally with the moving plate. Because the weight of the moving plate and half mold itself is very large, and the weight of the driving motor makes the driving motor drive the moving plate. At the same time as the half mold, it must drive its own weight to carry out the operation, which undoubtedly increases the power consumption of the driving mechanism, and at the same time greatly reduces the mold clamping efficiency of the mold body, which has a great impact on the injection molding efficiency.

At the same time, the traditional injection molding machine drives the moving plate to close the mold through the driving mechanism. It is only a simple linear drive, and the force on the moving plate is uneven, resulting in the inability to accurately close the first and second half molds, and the mold body The precision of mold clamping is not high, resulting in lower quality of injection molding

Moreover, the driving mechanism will inevitably fail. Once the driving mechanism fails, the equipment cannot stop working in time due to the lack of any detection mechanism or induction mechanism. The first half mold and the second half mold may continue to close the mold under the fault state Injection molding, resulting in unqualified injection molding quality, seriously affects product quality, and also causes a huge waste of energy, which is not conducive to the long-term development of enterprises
