Description

M261356 IV. Creation Instructions (1) ----- [Technical Field to which the New Type belongs] This creation is a two-plate composite direct-pressure sandwich mold structure, especially one. High-pressure mold opening or high-pressure closing molds are used to achieve instant pressure. [Previous technology] According to the general direct injection driven equipment such as injection molding machines, the mold can be tightened and clamped to avoid the smell of coal. Lecturer 々πri t ti, brother, Zhai Zhenshi excessive internal pressure makes the mold Accidental retreat is dangerous, so most of them have a set of clamping structure on the machine. The traditional clip mold structure is mainly shown in the eighth to tenth figures. The direct name system includes fixed template (A), movable template (B), and press / clamp °.

The unit (D) and the fine-tuning positioning group (E), wherein: the fixed periphery (A) and the movable template (B) are relatively extended with a straight edge (, A1 V, and the pillar Ul) at the outer periphery. The upper part is provided with the desired tooth (All), and a quick oil cylinder (A2) is arranged between the fixed template (A) and the movable template (B). The telescopic rod (A21) of the quick oil cylinder (A2) is fixed to the movable template. (B), when the quick oil cylinder (A2) is actuated, the movable template must be used. ） Clamp and eject the mold relative to the fixed template (A), and set four sets of single-action pressurized pistons (C) on the movable template (β). The movable template (B) is actuated by the quick cylinder (A 2). When pressed against the mold of the fixed template (a), the high-pressure clamping operation can be performed again by the pressurizing piston (C).

In addition, the movable template (B) is provided with four sets of clamping units (d). The clamping unit includes a semicircular clamping block (D1), and the clamping block (D 丨) is provided at each clamping. The seat (D 2) is closed and opened by a set of oil cylinders (D 3).

Page 5 M261356 IV. Creation instructions (2) The fine-tuning positioning group (E) is composed of several sprockets (E 1) and springs (e 2) (E 3), and is suitable for installation on the movable template (B). Therefore, when a new mold is installed, the fine adjustment positioning group (E) can be used to perform fine adjustment positioning in advance. When fine-tuning, 'the new mold is installed between the movable template (B) and the fixed template (A), and the movable template (B) is pulled by the quick oil cylinder (A 2) to make it fit with the mold, and then the clamp The holding unit (D) is closed, and after the pressure of the pressurizing piston (c) is released, the sprocket (e 1) in the fine adjustment positioning group (E) is rotated against the clamping element (D) to make the clamping block ( D 1) can be tightly fitted into the large column (a 1), so that the mold adjustment operation is completed. In addition, the fine adjustment positioning group (E) is provided with a strong spring (E3) as a supporting mold protection. When the internal pressure of the clamping mold is too large, and the movable template (B) is retracted, the strong spring (B) can be used. E 3) protects the trimming positioning group (E) from damage due to impact. > β Looking at the above conventional structure, it is not difficult to notice that it still has the following shortcomings, the main reasons are summarized as follows: 1 · The general mold opening force needs to be about 1/1 0 to 1/15 And fast = the cylinder needs to move quickly due to space constraints, and its power is generally about 1/40 to 1/50 of the clamping force, and its pressurized oil cylinder system is a single-acting piston, which requires For high-speed mold opening of high-speed oil cylinders, the mold release force and clamping force are obviously not good. If the conventional structure needs to increase the mold opening force of fast oil cylinders, it needs to be boosted by 2 to 3 times. For injection molding machines, it is already super The range of high pressures increases concerns about leaks. 2 · Fine-adjustment positioning group § is placed on the movable template again. When the mold is pressurized, the clamping nut is fixed to the large ridge and the inner mold room is too large, so that the movable template is retracted.
