Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.

Referring to fig. 1-5, the present invention provides a technical solution: the utility model provides a combination formula sliding die that interior awl bulkhead was used, including setting up lower bolster 6 in base 1 top, well template 5, cope match-plate pattern 4 and mount 2, mount 2 is fixed in base 1's top, be provided with bearing bar 21 on the mount 2, lower bolster 6 is placed on base 1, well template 5 is split type structure, well template 5 and 6 sliding connection of lower bolster, the perpendicular side of well template 5 is provided with slide 3, slide 3 and bearing bar 21 phase-match, cope match-plate pattern 4 lid closes in well template 5 top, the mould structure of having solved interior awl bulkhead production usefulness in the past is not good, the problem of drawing of patterns difficulty.

The number of the middle templates 5 is at least two, the bottom of the middle template 5 is provided with a guide sliding block 51, the upper end face of the lower template 6 is provided with a guide sliding groove, the guide sliding grooves are matched with the guide sliding block 51, when the lower template 6 is ejected upwards, the two middle templates 5 are acted with upwards force, meanwhile, the middle templates 5 are integrally connected with the slide ways 3, and the slide ways 3 are acted with the horizontal force of the bearing rods 21, so that the middle templates 5 are opened outwards along the guide sliding block 51.

When the upper template 4, the middle template 5 and the lower template 6 are in a die assembly state, the contact surfaces of the upper template 4, the middle template 5 and the lower template 6 are flush, so that the injection molding materials are prevented from overflowing;

the bottom of the upper template 4 is provided with a convex die 41, one end of the convex die 41 is of a spherical structure, and when the upper template 4, the middle template 5 and the lower template 6 are in a die closing state, a product cavity is formed among the upper template 4, the middle template 5 and the lower template 6, so that an inner cone choke plug of a product is cooled and formed.

The slideway 3 is in a long strip structure, the included angle between the slideway 3 and the base 1 is 45-60 degrees, the horizontal component force of the middle template 5 is larger than the vertical component force, the resistance is reduced, and the jamming is prevented.

A jacking component 7 is arranged between a lower template 6 and a base 1, and the jacking component 7 is a hydraulic rod or an electric telescopic rod and is used for jacking the lower template 6.

As an embodiment of the present invention: in the die, because the middle of a die cavity of the middle die plate 5 is small, the middle die plate 5 is divided into two halves for facilitating demoulding and taking out products, the slide ways 3 are fixed on two sides, the bearing rod 21 is clamped into the slide ways 3, the bearing rod 21 is fixed by the fixing frame 2, the fixing frame 2 is fixed on the bottom plate, and a sliding plane is arranged between the middle die plate and the lower die plate 6;

when the die is closed, the jacking assembly 7 drives the lower template 6 and the middle template 5 to descend to the lower plate of the vulcanizing equipment of the base 1, the bearing rod 21 is clamped at the top of the slideway 3, and the left middle template 5 and the right middle template 5 are folded; the mould is completely closed, and the rubber material is injected to start production;

after the product shaping, the die sinking, cope match-plate pattern 4 separates with well template 5, lower bolster 6, then jack-up subassembly 7 holds up lower bolster 6 and well template 5, and when well template 5, lower bolster 6 rose, because of mount 2 is fixed, partial part separates about slide 3 and the bearing drags well mould, and the product is just easily drawn and is taken out after the part.

Because the performance requirement of the product itself, partial product in the lower template 6 can not have the joint line, because the die cavity of the lower template 6 is an integral structure, the product only needs to be lifted and pulled to be separated from the lower template 6, so the requirement can be met, and the joint line can be arranged on the outer side of partial product of the middle template 5, so the design of the middle template 5 is reasonable.
