Abstract

The utility model belongs to a pressure forming apparatus, particularly an improved rubber plug press mould apparatus; the improved rubber plug press mould apparatus comprises an upper mould plate 1, a mould cavity plate 3 which is fixed with a compound plate 2. The mould cavity plate 3 and the compound plate 2 are matched with each other through a guiding and positioning pin 4 and a positioning hole 5 which are respectively arranged on the mould cavity plate 3 and the compound plate 2. Back projection 6 is arranged in the middle of the back part of the upper mould plate. The utility model can enable a pressed semi-product to be provided with a concave zone in order to counteract the thickened part of the middle part of the semi-product at the time of heating sulfuration, so that the thickness of a final product is uniform. Therefore, the quality of products is raised.

Description

The rubber stopper die arrangement that the patrix strip back of the body is protruding

The utility model belongs to pressure forming machine, mainly is a kind of improved rubber stopper die arrangement.

Existing rubber stopper die arrangement mainly contains cope match-plate pattern and cavity plate, between put into film and place the moulding of press pressurized, heated, but owing to can shrink behind the semi-finished product baking, often make that the uniform semi-finished product of thickness that just extruded thicken the middle part when finished product, thereby influenced product quality.

The purpose of this utility model is in order to overcome the deficiency of above-mentioned technology, and provides a kind of product final thickness uniform rubber stopper die arrangement.

The utility model is realized by following scheme.This device comprises cope match-plate pattern and is fixed with the cavity plate of compound plate, and the two matches by guide positioning pin and the locating hole that sets up separately on it, and it is protruding that its improvements are that middle part, cope match-plate pattern back is provided with the back of the body.The elastic deformation that produces when utilizing the cope match-plate pattern pressurized like this makes the semi-finished product middle part that has just suppressed recessed, and the recessed degree of depth is made peace greatly, and produce to shrink caused amount of swelling suitable for the semi-finished product baking.Carry on the back protruding amount and cope match-plate pattern material, thickness, size, film prescription, thickness, specification, and factor such as pressure is relevant, this can be determined by experiment.The utility model carry on the back protruding length (a) and wide (b) be cope match-plate pattern long and wide 1/2 to 1/3, carry on the back protruding and gradients edges of boards are 1: 80-120 is advisable.

Fig. 1 is the utility model schematic diagram;

Fig. 2 is the cope match-plate pattern vertical view.

Below in conjunction with accompanying drawing the utility model and embodiment are further described.See Fig. 1, this device comprises cope match-plate pattern 1, is fixed with the cavity plate 3 of compound plate 2, and its big or small material is 200mm * 155mm, thick 20mm, No. 45 steel; The two is by setting up separately on it

Guide positioning pin 4 and locating hole 5 match, and it is protruding 6 to be provided with the back of the body in the middle of the cope match-plate pattern back, and its length and width are 90mm * 60mm (see figure 2), carry on the backs protruding and gradients edges of boards are 1: 100.

The utility model cope match-plate pattern establish the back of the body protruding after, can make the semi-finished product that suppress reserve pit, the thickening of middle part during with the payment baking makes final product thickness even, improved product quality.
