Abstract
The utility model relates to the field of moulds, in particular to a device for preventing strain of a fixed mould elastic block, which is used for solving the problem that strain is generated because of sliding between a fixed mould slide block and a push plate. The device comprises the push plate, wear-resisting plates, elastic blocks, the slide block, slant guide posts, springs and a fixed mould core, and is characterized in that: an insert fixing plate is arranged above a bottom plate; the push plate is arranged above the insert fixing plate; the wear-resisting plates are arranged on the upper part of the push plate; the elastic blocks are arranged above the wear-resisting plates; the slide block is arranged on the upper parts of the elastic blocks; and the fixed mould core is arranged above the slide block. The device has the advantages that: the structure is simple and compact; during mould production, the wear-resisting plates and the elastic blocks are additionally arranged between the slide block and the push plate, and in a demoulding process, the elastic force of the elastic blocks is higher than that of the springs, so the slide block and the push plate are separated; the strain generated when the slide block and the push plate are stressed because of contact friction is avoided; the quality of a product is improved; the yield of the product is increased; and the using requirement of the product is met.
Description
Technical field
The utility model relates to mould applications, and particularly a kind of be used to solve between cover half slide block and the push pedal slides and produce the anti-device of pulling of cover half bullet piece of the problem of pulling.
Background technology
In plastic mould product stripping process, usually mould product is under the effect of spring force, slide block will be close to push pedal and slide, in this process, slide block and push pedal are easy to stressed pulling, thereby cause die products to produce burr, have a strong impact on the quality of mould product, can't satisfy instructions for use, product percent of pass descends.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned not enough problem, provides a kind of and avoids between cover half slide block and the push pedal sliding and produce that the cover half bullet piece of pulling is anti-pulls device, and simple in structure, practicality is stronger.
The technical solution adopted in the utility model is: the anti-device of pulling of a kind of cover half bullet piece, comprise push pedal, wearing plate, elastomer block, slide block, Angle Pin, spring and cover half benevolence, it is characterized in that: the mold insert fixed head is installed on the base plate, push pedal is installed on the mold insert fixed head, wearing plate is installed on push pedal top, elastomer block is installed on the wearing plate, slide block is installed on elastomer block top, cover half benevolence places on the slide block, stripper plate and panel are installed on the cover half benevolence successively, Angle Pin is connected between push pedal and the stripper plate, and spring is installed on the Angle Pin.
Described Angle Pin and spring have two groups, are symmetrically distributed in the push pedal both sides.
Described elastomer block is made by the material that can have higher elasticity and intensity, excellent abrasive, oil resistivity, fatigue durability and anti-vibration resistance in the hardness range of broad, as polyamine fat.
Described elastomer block and the wearing plate that is installed between push pedal and the slide block has 2 groups or 4 groups, and is symmetrically distributed.
The utility model is simple in structure, compact, when mould is produced, between slide block and push pedal, increase wearing plate and elastomer block, in knockout course, the elastic force of elastomer block is greater than the elastic force of spring, thereby makes slide block and push pedal keep apart, that has avoided that slide block and push pedal produce because of contact friction is stressed pulls, improve the quality of product, improved the qualification rate of product, satisfied the instructions for use of product.
To sum up, the cover half bullet piece that the utility model can provide is simple in structure, convenient and practical, take up room little is anti-pulls device, has simple to operately, and cost of manufacture is low, the advantage that practicality and reliability are stronger.
Description of drawings
Accompanying drawing 1 is the anti-structural representation of pulling device of a kind of cover half bullet piece.
Among the figure: 1. panel, 2. stripper plate, 3. solid plate, 4. elastomer block, 5. wearing plate, 6. push pedal, 7. mold insert fixed head, 8. base plate, 9. slide block, 10. Angle Pin, 11. springs, 12. cover half benevolence.
The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing, but the utility model is not limited to specific embodiment.
As shown in Figure 1, a kind of cover half bullet of the utility model piece is anti-pulls device, comprises push pedal 6, wearing plate 5, elastomer block 4, slide block 9, Angle Pin 10, spring 11 and cover half benevolence 12.
Wherein, mold insert fixed head 7 is installed on the base plate 8, push pedal 6 is installed on the mold insert fixed head 7, wearing plate 5 is installed on push pedal 6 tops, elastomer block 4 is installed on the wearing plate 5, elastomer block 4 is made by the material that can have higher elasticity and intensity, excellent abrasive, oil resistivity, fatigue durability and anti-vibration resistance in the hardness range of broad, as polyamine fat; The elastomer block 4 and the wearing plate 5 that are installed between push pedal 6 and the slide block 9 have 4 groups, and are symmetrically distributed
In knockout course, owing between slide block and push pedal, increased wearing plate and elastomer block, the elastic force of elastomer block is greater than the elastic force of spring, thereby make wearing plate 11 eject 0.2mm, slide block and push pedal are kept apart, that has avoided that slide block and push pedal produce because of contact friction is stressed pulls, and has improved the quality of product, has satisfied instructions for use.
