Abstract

The utility model discloses a slide guiding mechanism used in medium and large-sized moulds. The slide guiding mechanism comprises a molding sliding block (1), two slide guiding blocks (2), a guide bushing (3) and a screw (4), wherein, slide guiding grooves (5) are directly processed on the two slide guiding blocks while the base angles of which are bidirectionally located on a sleeve plate (6) respectively and connected together by the screw (4); the molding sliding block can slide in the slide guiding grooves (5) of the two slide guiding blocks (2). The slide guiding mechanism of the utility model used in large and medium-sized moulds with independent slide guiding blocks has the main advantages of (1) facilitating the machining and heat processing; (2) favoring maintenance and replacement; (3) being easy to be assembled and disassembled when the sliding block is deadly blocked; (4) improving the torsional and bending rigidity of the slide way by the locating parts of the slide guiding blocks during the core-pulling along the side way due to the slide guiding blocks are bidirectionally located. In addition, the slide guiding mechanism of the utility model is also adopted in the design of a plurality of beveled pin core-pulling moulds and proves to achieve better results.

Description

A kind of guide mechanism that is used for medium-and-large-sized mould

Technical field

The utility model relates to a kind of slide guide structure of mould molding slide block, especially can realize smooth slide guide, be convenient to processing and heat treated independent slider guide structure.

Background technology

Forming slide undercut loose core and reseting procedure in, require it to move back and forth reposefully along certain direction, this process is finished in guide runner.Different according to side core size, shape and requirement on the mould, structure such as slide block is also different with the fit form of guide runner, generally adopts T-slot or dovetail groove slide guide, and monoblock type is arranged, and integral cap is board-like, and partial cover is board-like.Monolithic construction compactness wherein is used for the core-pulling mechanism of small mould more, but processing difficulties, slide guide is not easy to grinding after partly hardening, and precision also is not easy to guarantee, and assembling is also inconvenient.

Summary of the invention

The purpose of this utility model provides a kind of guide mechanism that is used for medium-and-large-sized mould, and this guide mechanism slider guide is convenient to machining and heat treatment, is convenient to maintenance and replacing, when slide block is stuck, be convenient to dismounting, and slider guide can increase the bending-twisting rigidity of slideway.

The technical scheme that realizes above-mentioned purpose is (referring to Fig. 1, Fig. 2):

A kind of guide mechanism that is used for medium-and-large-sized mould comprises 1, two slider guide 2 of forming slide, and guide pin bushing 3 and screw 4 directly are processed with guide runner 5 on slider guide, and the two-way key in slider guide base angle is positioned on the cage plate 6, and is connected to an integral body with screw 4.Forming slide 1 can slide in the guide runner 5 of two slider guides 2.

What the utility model adopted is independent slider guide, and guide runner directly processes on slider guide, and material therefor is 45 steel.For the ease of processing with prevent heat treatment deformation, adopts modified milling shaping to 28～32HRC; Guide runner is handled by surface hardening at last, and hardness is 41～45HRC.Guide runner and slide block slide guide partly adopt matched in clearance, adopt H8/f8, and other all leaves the gap about 0.5～0.8mm everywhere.The surface roughness of mating part is Ra1.6～0.8 μ m.Guide runner and slide block keep certain length of fit.After slide block is finished the withdrawing action, its slipper is still whole or have the length of part to stay in the guide runner, the length that is slidingly matched of slide block is greater than 1.5 times of slide block width usually, and the length that is retained in the guide runner should be less than 2/3 of slide guide length of fit, otherwise, easy deflection when slide block begins to reset, even mold damage.

Steadily reliable for guaranteeing the motion of slide block in guide runner, no play and stuck phenomenon are made as shown in Figure 1 assembling form with slider guide and cage plate, are positioned on the cage plate by the two-way key in slider guide base angle, and are connected to an integral body with screw.The major advantage of this free-standing slider guide is: be convenient to machining and heat treatment; (2) be convenient to maintenance and replacing; (3) when slide block is stuck, be convenient to dismounting; (4) slider guide is two-way location, and the localization part of slider guide can increase the bending-twisting rigidity of slideway when side core-pulling.This slide guide structure adopts in many cover taper pins are loosed core the mould design, has all obtained better effects.

The implication of number in the figure: 1 forming slide, 2 slider guides, 3 guide pin bushings, 4 screws, 5 guide runners, 6 cage plates, 7 screw holes, 8 dowel holes.

The specific embodiment

The utility model embodiment as shown in drawings.The guide mechanism that is used for medium-and-large-sized mould that Fig. 1 is represented comprises 1, two slider guide 2 of forming slide, and guide pin bushing 3 and screw 4, slider guide 2 are provided with the guide pillar that is used for active and inactive mold location or the position of guide pin bushing.Fig. 2 shows that directly being processed with 5, two two-way respectively keys in slider guide 2 base angles of guide runner on two slider guides 2 is positioned on the cage plate 6, and is connected to an integral body with screw 4, and forming slide 1 can slide in the guide runner 5 of two slider guides 2.

In Fig. 3, slider guide structure shown in Figure 4, have guide pillar or dowel hole 8 on the slider guide 2, screw hole 7, guide runner 5.The material of slider guide is 45 steel, adopt modified to 28～32HRC milling be shaped; Guide runner is handled by surface hardening at last, and hardness is 41～45HRC.The slide guide of guide runner partly adopts matched in clearance H8 (50 ^{+ 0.052}), the surface roughness of mating part is Ra1.6～0.8 μ m.
