Abstract
The utility model relates to a square guide pillar structure in an injection molding die. The square guide pillar structure is composed of a fixed die (1), a guide pillar (2), a square guide pillar (3), a square guide pillar fixing screw (4), a guide sleeve (5), a movable die (6), an abrasion-resisting block (7) and an abrasion-resisting block fixing screw (8), wherein the square guide pillar (3) and the guide pillar (2) are mounted on the fixed die (1) and fastened through the square guide pillar fixing screw (4); and the abrasion-resisting block (7) and the guide sleeve (5) are mounted on the movable die (6) and fastened through the abrasion-resisting block fixing screw (8). The square guide pillar structure is characterized in that the fixed die (1) and the movable die (6) are connected through the guide pillar (2), the guide sleeve (5), the square guide pillar (3) and the abrasion-resisting block (7). The square guide pillar structure has the biggest characteristic of having no fit clearance, thereby improving the positioning accuracy. The square guide pillar structure is suitable for situations with requirements of accurately positioning the large-size and medium-sized dies. The square guide pillar structure is high in accuracy, balanced in force bearing, good in stability, long in service life and low in cost, thereby being convenient for popularization and promotion.
Description
Technical field
The utility model relates to injection mold, especially the square guide pillar structure in the injection mold guidance system.
Background technology
When injection mold is closed, be to guarantee cavity shape and accuracy of gauge, should be according to a certain direction and the position matched moulds, so must be provided with the guide-localization system, modal guide-localization system establishes 4 pairs of guide pillars and bushes of working in coordination around mold cavity.Three effects of the lateral pressure that guidance system produces when mainly containing guiding, locate and bearing injection moulding.
When large-scale, the dark chamber of moulding, thin-walled and high accuracy plastic, should adopt higher closing precision between the active and inactive mold.For the large thin-wall container, even if active and inactive mold matched moulds off-centre will cause wall unevenness, make a side charging faster than opposite side, owing between the guide pillars and bushes fit clearance is arranged, can not accurately locate.For the asymmetric plastic of thin-walled shape, injection pressure also can produce lateral thrust, if side force is born by guide pillar fully, can take place then that guide pillar is stuck, increase wearing and tearing when damage or die sinking, causes guide pillars and bushes to cooperate and loses efficacy.
Summary of the invention
At above-mentioned deficiency, the purpose of this utility model is to provide the square guide pillar structure in a kind of injection mold, it is the potential risk that mould exists in the injection moulding production process, the problem that the utility model solves is, provide a kind of simple in structure, use in stable condition reliable side's guide pillar structure accurately to locate, solve the deviations defective when having the injection mold matched moulds now.
The technical solution of the utility model realizes in the following manner: the square guide pillar structure in a kind of injection mold, by cover half, guide pillar, side's guide pillar, side's guide pillar hold-down screw, guide pin bushing, dynamic model, wear-resistant block and wear-resistant block hold-down screw are formed, side's guide pillar and guide pillar are installed on the cover half, and fastening by square guide pillar hold-down screw, wear-resistant block and guide pin bushing are installed on the dynamic model, fastening by the wear-resistant block hold-down screw, it is characterized in that: described fixed half and moving half is connected with square guide pillar, wear-resistant block by guide pillar, guide pin bushing.
Described side's guide pillar and wear-resistant block are no less than two covers in fixed half and moving half.
Described side's guide pillar and guide pillar top end face flush, and exceeding the highest moulding section is 50mm, and square guide pillar and wear-resistant block are installed in the groove that the mould side processes, and embed the mould side.
Described side's guide pillar is Cr12, and HRC 48～50; Wear-resistant block is copper-base graphite.
The maximum characteristics of the utility model structure are that fit clearance is zero, can improve positioning accuracy, it is fit to the pinpoint occasion of big-and-middle-sized mould needs, and the utility model precision height, stress balance, good stability, long service life, with low cost are convenient to penetration and promotion.

The specific embodiment
Known by Fig. 1, square guide pillar structure in a kind of injection mold, by cover half 1, guide pillar 2, side's guide pillar 3, side's guide pillar hold-down screw 4, guide pin bushing 5, dynamic model 6, wear-resistant block 7, side's guide pillar 3 and guide pillar 2 are installed on the cover half 1, and wear-resistant block 7 and guide pin bushing 5 are installed on the dynamic model 6, it is characterized in that: described cover half 1 is connected by guide pillar, guide pin bushing 5 and square guide pillar, wear-resistant block 7 with dynamic model 6.
Side's guide pillar structure should adopt two covers at least in a secondary mould, large mold must use quadruplet, and square guide pillar 3 flushes with guide pillar 2 top end faces, exceeds the about 50mm of the highest moulding section, in order to protect the forming surface zone of cover half 1 when matched moulds.Side guide pillar 3 and wear-resistant block 7 all are mounted in the groove that the mould side processes, and embed the mould side, can guarantee the aesthetic property of mould appearance.When large-scale, the dark chamber of moulding, thin-walled and high accuracy plastic, this side's guide pillar structure not only can play accurate positioning action, and the mutual padlock of active and inactive mold behind the matched moulds, can limit die cavity and expand, and increases the rigidity of mould.Wear-resistant block adopts copper-base graphite, and anti-wear performance and greasy property obviously improve, mould is long-term use after, when wear-resistant block 7 wear out failures, dismounting and change is very convenient from the mould, improves the efficient of mold repair.
