Abstract

The utility model discloses an oblique core-pulling mechanism for a sliding block of a plastic pipe mould. The oblique core-pulling mechanism disclosed by the utility model comprises a cavity and a core mounted in a mould bracket of the mould; a formed plastic pipe is arranged between the cavity and the core; a touching-penetrating position is formed in the plastic pipe; the oblique core-pulling mechanism is characterized in that an oblique guide sliding block is mounted on the mould bracket; a sliding block base is arranged on the oblique guide sliding block; the sliding block base is connected with the core; a cylinder plate is mounted at the side wall of the mould bracket; a cylinder is mounted on the cylinder plate; and a piston rod of the cylinder is connected with the sliding base. The oblique core-pulling mechanism for the sliding block of the plastic pipe mould disclosed by the utility model adopts an oblique core-pulling mechanism of a sliding block; in working, the cylinder drives the sliding base connected with the core to move along the guide sliding block with obliquity, thereby achieving fast separation of the core from the touching-penetrating position of the plastic pipe and enabling the core and touching-penetrating position of the plastic pipe not to be rubbed and clamped; the oblique core-pulling mechanism for the sliding block of the plastic pipe mould disclosed by the utility model guarantees that the plastic pipe is not damaged, also drives the plastic pipe to be slightly separated from the cavity in core pulling, so that the plastic pipe is relatively easy to eject out; the product cannot be damaged by jacking; the size of the mould is reduced; and the invested cost is saved.

Description

The plastic pipe fitting mould sliding block inclined is to core-pulling mechanism

Technical field

The utility model relates to a kind of plastic pipe fitting mould sliding block inclined to core-pulling mechanism, belongs to the mould of plastics field.

Background technology

At present, when adopting mould of plastics to produce plastic pipe, if a plurality of zones (touch and wear the position) of wearing of touching are arranged in pipe fitting, according to traditional design, the structure that adopts moving platen to float, making inserts separates with core and does not produce friction, its shortcoming is the mould inside complex structure, and die boundary dimensions is large, and dismounting is inconvenient, particularly to injection machine require highly, cost investment is large.

Summary of the invention

The purpose of this utility model is in order to overcome the shortcoming of prior art, provide a kind of slide block along moving with gradient slider guide, thereby realize that core separates rapidly with inserting, and makes it not produce friction pairs, the mould volume is little, and the plastic pipe fitting mould sliding block inclined that cost is economized is to core-pulling mechanism.

The utility model plastic pipe fitting mould sliding block inclined to the technical scheme of core-pulling mechanism is: comprise the die cavity and the core that are arranged in the mould mould bases, the plastic pipe that moulding is arranged between die cavity and core, be shaped with in plastic pipe to touch and wear the position, it is characterized in that installing on described mould bases oblique slider guide, on oblique slider guide, take-up housing is set, take-up housing connects core, and the sidewall of described mould bases is installed tank plate, oil cylinder is installed, the piston rod connection sliding block seat of oil cylinder on tank plate.

Plastic pipe fitting mould sliding block inclined of the present utility model is to core-pulling mechanism, adopt sliding block inclined to core-pulling mechanism, during work, oil cylinder drives the take-up housing of connection core along moving with gradient slider guide, thereby realize core and touching of plastic pipe wear the position separate rapidly, make it not produce the situation of friction pairs, guaranteed not damaging of plastic pipe, and when loosing core, also drive plastic pipe and broken away from by a small margin die cavity, just lighter for the ejecting of plastic pipe, product can not push up bad, reduce the mould volume, save cost and drop into.

Description of drawings

Fig. 1 is that the utility model plastic pipe fitting mould sliding block inclined is to the core-pulling mechanism structural representation.

The specific embodiment

The utility model relates to a kind of plastic pipe fitting mould sliding block inclined to core-pulling mechanism, as shown in Figure 1, comprise the die cavity 1 and the core 2 that are arranged in mould mould bases 9, the plastic pipe 3 that moulding is arranged between die cavity 1 and core 2, be shaped with in plastic pipe 3 to touch and wear position 4, it is characterized in that installing on described mould bases 9 oblique slider guide 5, on oblique slider guide 5, take-up housing 6 is set, take-up housing 6 connects core 2, the sidewall of described mould bases 9 is installed tank plate 7, oil cylinder 8, the piston rod 81 connection sliding block seats 6 of oil cylinder 8 are installed on tank plate 7.This programme adopts sliding block inclined to core-pulling mechanism, during work, oil cylinder 8 drives the take-up housing 6 of connection core 2 along moving with gradient slider guide 5, thereby realize that core 2 and touching of plastic pipe 3 wear the position and 4 separate rapidly, make it not produce the situation of friction pairs, guaranteed not damaging of plastic pipe 3, and when loosing core, also drive plastic pipe 3 and broken away from by a small margin die cavity 1, just lighter for the ejecting of plastic pipe, product can not push up bad, reduces the mould volume, saves cost and drops into.
