Description

Technical Field

[0001] The utility model specifically relates to the technical field of accurate positioning mold frames, in particular to a mold frame device with an accurate positioning structure. Background Art

[0002] The die frame is the support of the mold. For example, the part that combines and fixes the various parts of the mold according to a certain rule and position on the die-casting machine and enables the mold to be installed on the die-casting machine for work is called the die frame. It consists of an ejection mechanism, a guide mechanism, a pre-reset mechanism, a die foot pad, and a seat plate.

[0003] The mold is an important parts processing device in modern industry. Through the mold, the parts can be effectively formed by stamping, blow molding and other processes. However, when the traditional mold is used, the two molds need to be accurately positioned when they work together. In order to ensure the perfect fit between the two molds, a positioning device is added to the equipment. In this way, the equipment needs to be positioned and adjusted before working, which will waste a lot of time when changing the mold.

[0004] After searching, Chinese patent publication number CN202122879381.3 discloses a cavity-type mold frame with a guiding and positioning structure; it includes a mold frame base, the top of the mold frame base is fixedly connected to a carrier plate, and the top of the carrier plate is provided with a positioning mechanism; the positioning mechanism includes a groove opened on the top of the carrier plate, a mold core is provided above the carrier plate, and transverse grooves are opened on the front and rear sides of the top of the carrier plate, and one side of the inner wall of the two transverse grooves is fixedly connected to a transverse rod, and the opposite ends of the two transverse rods are slidably connected to a transverse tube, and the opposite ends of the two transverse rods penetrate the transverse tube and extend to the inside of the transverse tube, and the opposite ends of the two transverse tubes are fixedly connected to a trapezoidal block;

[0005] When the structure in the above patent is working, the hydraulic rod drives the rotating plate to rotate, so that the insertion rod and the vertical pipe bracket cooperate to achieve the positioning effect. However, when the rotating plate rotates, the insertion rod also rotates. In this way, when the insertion rod cooperates with the vertical pipe, the vertical pipe in the above patent will block the insertion rod. The insertion rod in the above patent can only be inserted into the vertical pipe by moving up and down and then cooperated with the sliding rod and the fixed block; and the plate in the above patent is fixedly installed on the mold frame base, so the distance between the mold core and the top plate is large, and it is impossible to effectively realize the restricted positioning of the material inside the mold core;

[0006] In view of the above situation, we provide a mold frame device with a precise positioning structure. In this device, the lower film is installed on the mobile plate, and the upper mold is installed on the flap. When cooperating, the upper mold is driven to rotate by the flap to achieve effective cooperation with the lower film. When the distance between the upper mold and the lower film is large, the second electric push cylinder can also be used to drive the mobile plate to move upward to achieve cooperation with the upper mold. When the mobile plate moves upward, the cooperation between the sliding column and the sliding groove at the bottom can effectively prevent the occurrence of deviation during the movement, and effectively ensure the efficiency of the cooperation between the upper mold and the lower film.
