High-temperature-resistant rapid forming injection mold

Abstract

The invention discloses a high-temperature-resistant rapid forming injection mold which comprises a base, sleeve columns are arranged on the two sides of the top of the base, guide sleeves matched with each other are arranged on the outer sides of the two sets of the sleeve columns, a lower mold base is arranged in the middle of the top of the base, and guide pipes are arranged on the two sides of the interior of the lower mold base. A gear A is arranged on the side, close to the guide pipes, of the top of the interior of the lower mold base, telescopic rods are symmetrically arranged in the middle of the bottom of the lower mold base, and injection mold bases connected with each other are arranged on the tops of the two sets of the telescopic rods. Through mutual correspondence of an upper mold base and the injection mold base, the upper mold base can descend to drive a sleeve rod, a rack A, the guide pipes, the gear A and a rack B to generate linkage fit, so that the upper mold base in the descending process is in mutual corresponding contact with the injection mold base which is in linkage with parts for lifting. According to the mold combining structure, mold combining work is done through upper and lower two-group linkage type splicing, and the mold combining precision and efficiency are greatly improved.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to a high temperature resistant rapid prototyping injection mold. Background technique [0002] Injection molding is a tool for producing plastic products, and it is also a tool for giving plastic products a complete structure and precise dimensions. Injection molding is a processing method used in the mass production of certain complex-shaped parts. Specifically, it refers to melting plastic by heat. The injection molding machine injects into the mold cavity under high pressure, and after cooling and solidifying, the molded product is obtained. [0003] When the injection mold is closing the film, the movable upper mold generally presses and contacts the fixed lower mold to form an injection cavity. When the existing upper film is pressed and moved, although it already has a guiding structure, according to the injection molding of the mold Depending on the type and model, ...

Problems solved by technology

[0003] When the injection mold is closing the film, the movable upper mold generally presses and contacts the fixed lower mold to form an injection cavity. When the existing upper film is pressed and moved, although it already has a guiding structure, according to the injection molding of the mold Depending on the type and model, there may still be position shifts and leakage after the film is combined, and the pressing force of the lower film will be exerted on the upper film for a long time, resulting in loss of the lower die structure, reducing the service life of the components, and reducing the cost of the joint. The precision of film injection molding; when the injection molding molten material is feeding, it is easy to generate a large number of heat sources in the channel, which will generate extremely high temperature on the wrapped and sealed wall surface. If the heat-resistant structure here is insufficient, it will cause the pipe wall to crack. The molten material overflows, increasing the difficulty and inconvenience of injection molding work, and the injection port of the device is prone to rapid loss of heat source due to the necessary exhaust structure, causing the molten material to solidify in the guide tube of the molten material, which cannot be used normally. Circulation, further increases the difficulty of injection molding of molten materials, reduces the injection molding effect and pass rate of the mold; when the device drives the parts to move, it is easy to shake the moving structure, resulting in increased vibration of the combination of the upper film and the lower mold, which in turn makes the subject The damage increases, and when the injection molding melt is conveyed, it may generate a certain amount of noise, which reduces the protection of the injection molding structure
