Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of mould frame, more specifically, relate to a mould frame with good exhaust effect. BACKGROUND

[0002] Mould frame is the support of mould, such as die-casting machine each part of mould is combined and fixed according to certain rule and position, and the part that can make mould work installed to die-casting machine is called mould frame.

[0003] The upper die and the lower die of the traditional mould frame are guided through the cooperation of guide rods and guide sleeves, but the exhaust effect is not good, which leads to low smoothness, especially during the clamping process, the gas discharge is particularly not smooth, and the guide sleeve may be deformed when the pressure is too large.

[0004] In view of the above problems, the application number 202322736030.6, the application name is a mould frame with good exhaust effect, the upper surface of the spacer plate on the upper surface of the base is provided with a plurality of upper guide rods, the upper guide rod is provided with a gas guide groove on one side; The top plate is arranged on the upper surface of the upper die plate, the upper die plate is provided with a plurality of guide sleeves, the guide sleeves correspond to the positions of the upper guide rods and are in sliding cooperation with the corresponding upper guide rods, a first exhaust groove is formed on one side of the lower surface of the guide sleeve, a second exhaust groove is formed on one side of the lower surface of the upper die plate and corresponds to each guide sleeve, the second exhaust groove and the corresponding first exhaust groove are in communication with each other, and the end of the second exhaust groove away from the corresponding first exhaust groove is in communication with the outside of the upper die plate. The utility model has reasonable structure, the gas guide groove of the upper guide rod can smoothly exhaust during the lifting of the upper die, and during the clamping moment, the gas is guided through the gas guide groove and then discharged from the first exhaust groove and the second exhaust groove, further improving the smoothness during the clamping process.

[0005] Although the device has many beneficial effects, it still has the following problems: although the device improves the exhaust performance compared with the traditional mould frame and can achieve better exhaust effect, in actual application scenarios, especially in harsh working conditions, many drawbacks are still exposed, when used in such environment, a large amount of dust, metal debris and other impurities are filled in the surrounding air, these impurities are easily sucked into the guide sleeve during the clamping process, the impurities accumulate over time, which easily causes the exhaust hole to be blocked, once the exhaust hole is blocked, the gas cannot be smoothly discharged, the air pressure in the cavity will be unbalanced, which not only leads to the decline of product forming quality, such as air bubbles, material defects, but also seriously affects the clamping effect, so that the clamping process is no longer smooth, the positioning accuracy of the mould is also disturbed, thereby causing many inconveniences and troubles to the actual production operation, increasing the scrap rate and production cost, and reducing the production efficiency;

[0006] And in the process of guiding the sleeve and the guide rod are used in guiding cooperation, it often lacks effective buffer structure, in the long-term frequent mold closing operation process, the mold upper and lower mold closing speed if faster and impact force is larger, its guide rod will directly bear this strong impact and vibration, for a long time, the guide rod is prone to wear, deformation and even breakage, this not only will influence the guide rod's service life and guiding precision, also will lead to the whole mold's mold closing precision to decline, make the cooperation between each part of the mold appear deviation, and then bring great inconvenience and hidden trouble to the actual use.
