Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, and in particular to a horizontal single-shot injection molding machine. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. The injection system is responsible for heating and melting the plastic raw material and injecting it into the mold cavity. The mold closing system is used to open and close the mold and keep it closed during injection, bearing the cavity pressure. The hydraulic system provides power and precisely controls the movement of each component, while the electrical control system sets and monitors the equipment's operating parameters. Injection molding machines are widely used in many fields. In the packaging industry, they can produce various plastic bottles and boxes. In the electronics and electrical appliance field, they are used to manufacture various shells and components. With technological advancements, injection molding machines are moving towards high speed, high efficiency, precision, and energy saving. To save costs while meeting usage requirements, a horizontal single-shot injection molding machine is needed.

[0003] A search revealed Chinese Patent Publication No. CN203331330U, which discloses a horizontal-vertical multi-mold injection molding machine, including a base. A horizontally arranged injection system and a vertically arranged clamping system are mounted on the base. The vertical clamping system includes multiple guide pillars, each passing through a worktable and capable of vertical movement along the pillars. An upper mold plate is fixed to the upper end of each guide pillar, and a lower mold plate is fixed to the lower end. The lower mold plate is connected to a clamping device that drives the guide pillars to move vertically. A lower mold is mounted on the worktable. A rotary drive device is provided on the upper mold plate, and a groove is provided on the lower end face of the upper mold plate that allows the rotary drive device to rotate. The present invention provides a horizontal and vertical multi-mold injection molding machine that can transfer the cooling of the preform to the outside of the mold cavity, realize the removal of the preform outside the mold, and has a small mold closing mechanism. The rotating template under the drive is equipped with at least two upper molds symmetrical about its center. This invention not only improves the cooling effect of the preform and helps to shorten the molding cycle of the preform, but also makes the removal of the preform simple and easy to automate. While simplifying the injection molding device, it improves production efficiency and reduces production costs. However, when the production demand is low, the horizontal and vertical multi-mold injection molding machine will experience a functional process, resulting in the waste of resources.
