Abstract
The utility model relates to the field of plastic molds, in particular to a structure for a plastic mold for preventing products from sticking on a sliding block. The structure for the plastic mold for preventing the products from sticking on the sliding block comprises a fixed template and a moving template, wherein the bottom of the fixed template is fixed with an oblique guide pillar through a locking block; the upper part of the moving template is provided with the sliding block; the oblique guide pillar slides in the sliding block; the sliding block is provided with a groove which limits an ejection pin a and an ejection pin b to move; the ejection pin a is butted against the ejection pin b; one surface of the locking block close to the sliding block is provided with a section of vertical surface; the ejection pin a passes through the groove and is butted against the vertical surface; and the locking block ejects the ejection pin a to push the ejection pin b to horizontally move. The structure has the advantages that: a split structure is adopted, the pressure on places easy to break is smaller, the production cost of the mold is not changed, and the production efficiency of the mold is improved.
Description
Technical field
The utility model relates to the mould of plastics field, and especially a kind of mould of plastics prevents the structure of the sticking slide block of product.
Background technology
Since some plastic product can not the demoulding the position need make to loose core slide block could the demoulding, and product is complicated in the slide block, when slide block skids off; Product is bonded on the slide block easily, causes the product stripping difficulty, therefore needs the product in the structural limitations slide block to move; We adopt thimble 11 limits product of integral type to move usually, and shown in Fig. 2 and 3, this mode has obvious defects in use; The thimble 11 that is exactly this integral type ruptures easily; Need often to change, influence the mould ordinary production, increase production cost and maintenance cost.
Summary of the invention
For the technical problem that the thimble that solves above-mentioned integral type ruptures easily, the utility model provides a kind of mould of plastics to prevent the structure of the sticking slide block of product.
The technical scheme of the utility model is following:
A kind of mould of plastics prevents the structure of the sticking slide block of product; Comprise solid plate and moving platen, said solid plate bottom is fixed Angle Pin through latch segment, and said moving platen top is provided with slide block; Said Angle Pin slides in slide block; Said slide block is provided with and limits thimble a and the movable groove of thimble b, and said thimble a and thimble b offset, and latch segment simultaneously has one section vertical plane near slide block; Said thimble a passes groove and said vertical plane offsets, and pushes thimble a through latch segment and promotes thimble b horizontal movement.
As preferably, said slide block is provided with wear-resistant block a, and said wear-resistant block a contacts with latch segment.
As preferably, said moving platen is provided with wear-resistant block b.
Use the technical scheme of the utility model, adopt split-type structural, the pressure that the easy fracture place receives is littler, and the cost of manufacture of mould do not have anything to change yet, and has improved the productivity effect of mould.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation before this improvement;
Fig. 3 is the structural representation of thimble before this improvement;
Fig. 4 is the structural representation of thimble a8 in the utility model;
Fig. 5 is the structural representation of thimble b9 in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Embodiment
Prevent that like Fig. 1, a kind of mould of plastics shown in 4 and 5 product from gluing the structure of slide block, comprise solid plate 1 and moving platen 7, said solid plate 1 bottom is fixing Angle Pin 3 through latch segment 2; Said moving platen 7 tops are provided with slide block 5, and said Angle Pin 3 slides in slide block 5, and said slide block 5 is provided with and limits thimble a8 and the movable groove 12 of thimble b9; Said thimble a8 and thimble b9 offset; Latch segment 2 has one section vertical plane, said thimble a8 to pass groove 12 near slide block 5 one sides and said vertical plane offsets, and pushes thimble a8 through latch segment 2 and promotes thimble b9 horizontal movement; Latch segment 2 goes the inside jacking of part that thimble a8 is exposed, and promotes thimble b9.
Said slide block 5 is provided with wear-resistant block a4, and said wear-resistant block a4 contacts with latch segment 2.
Said moving platen 7 is provided with wear-resistant block b6.
During die sinking, because that Angle Pin 3 is fixed on the solid plate 1 is motionless, and slide block 5 is fixed in the moving platen 7; Slide block 5 be along with moving platen 7 will move downward, so slide block 5 is under the effect of Angle Pin 3, and outwards slide on (left side) on moving platen 7; Owing on the latch segment 2 straight section is arranged in the incipient stage; Make thimble a8 and thimble b9 keep original position motionless, so product 10 also keeps motionless, play the effect that prevents sticking to mould; Along with the disappearance of latch segment 2 upper straight sections, thimble a8 and thimble b9 again along with slide block 5 together outwards (left side) slide; Otherwise during matched moulds, slide block 5 is along with moving platen 7 moves upward, so slide block 5 inwardly slides on moving platen 7 under the effect of Angle Pin 3, and shifts thimble a8 and thimble b9 onto desired location, slides into the position until slide block 5.
Claims (3)
1. a mould of plastics prevents that product from gluing the structure of slide block; Comprise solid plate (1) and moving platen (7); It is characterized in that: said solid plate (1) bottom is fixing Angle Pin (3) through latch segment (2); Said moving platen (7) top is provided with slide block (5), and said Angle Pin (3) slides in slide block (5), and said slide block (5) is provided with and limits thimble a (8) and the movable groove (12) of thimble b (9); Said thimble a (8) and thimble b (9) offset; Latch segment (2) has one section vertical plane, said thimble a (8) to pass groove (12) near slide block (5) one side and said vertical plane offsets, and pushes thimble a (8) through latch segment (2) and promotes thimble b (9) horizontal movement.
