Embodiment 1

[0021] Such as figure 1 As shown, an EPS plastic foam mold guide column includes a base 1, a guide sleeve 2 threadedly connected with the base 1, an end cover 8 is arranged on the top of the guide sleeve 2, and a guide hole 7 is provided on the end cover 8, and the guide hole 7 A guide post A4 is arranged inside, a sliding sealing gasket is installed between the guide hole 7 and the guide post A4, a rubber pad 10 is provided on the lower surface of the end cover 8, and an annular channel 81 is provided on the end cover 8, and the annular channel The top of 81 is provided with the ventilation hole 82 that communicates with it, the rubber pad 10 is fixed on the periphery of guide post A4, the baffle plate 3 is installed on the top of guide post A4, the bottom of guide post A4 is detachably connected with guide post B5, the guide post B5 The bottom is provided with a mounting groove 11, the two sides of the mounting groove 11 are equipped with stoppers 12, iron posts 13 are fixed...

Embodiment 2

[0024] Such as figure 2 As shown, the bottom of the iron column 12 is provided with a second magnet block 19 , and the second magnet block 19 repels the first magnet block 15 .

[0025] When this embodiment is used, since the second magnet block 19 and the first magnet block 15 repel each other, a buffering effect is given to the guide post during the descent of the guide post, and the guide post is limited so that the bottom of the guide post B5 Installed iron columns will not shift.

Abstract

The invention belongs to the technical field of molds and discloses a guide post for an EPS (Expandable Polystyrene) plastic foam mold. The guide post comprises a base, wherein a guide sleeve is in threaded connection with the base; an end cover is arranged at the top end of the guide sleeve; a guide hole is formed in the end cover; a guide post A is arranged in the guide hole; a sliding sealing washer is arranged between the guide hole and the guide post A; a guide post B is connected to the lower end of the guide post A; a fixing plate is connected to the top end of the guide post A; a rubber blanket is arranged on the lower surface of the end cover; an elastic element is arranged between the fixing plate and the end cover; a mounting groove is formed in the lower surface of the guide post B; baffle blocks are arranged at two sides of the inner wall of the mounting groove; an iron post is arranged between the baffle blocks; a circular truncated cone is fixed on the base; a groove matched with the iron post is formed in the upper surface of the circular truncated cone; a plurality of blind holes are formed in the inner wall of the guide sleeve; a first magnet block is arranged in each blind hole. The problems that the guide post is deformed due to excessively-high descending speed thereof, and a component connected with the guide post is offset in position are solved.

Description

technical field [0001] The invention belongs to the field of moulds, and in particular relates to guide posts for EPS plastic foam molds. Background technique [0002] EPS plastic foam is a kind of polymer material formed by dispersing a large amount of gas in the air and solid plastic. Because of its light weight, firmness, shock absorption, low moisture absorption, easy molding, good water resistance, heat insulation, and low price, it is widely used in packaging, heat preservation, waterproof, heat insulation, shock absorption and other fields. Therefore, the production of EPS plastic foam has broad prospects, and the production of EPS plastic foam is through mold injection molding, so the requirements for the mold are very high, and the mold guide post is an important component to ensure that the mold can be accurately injection molded. When the mold is clamped, it usually produces a certain impact force, which will cause the deformation of the guide post, and the guide...
