The ABS plastic wire coil molding die is provided with an upper die and a lower die and is characterized in that a pouring runner is formed in the central part of the upper die, a guide groove is formed in the periphery of the upper die, and the guiding groove and a guide pillar on the lower die are plugged together; the upper die and the lower die are respectively provided with an upper molding cavity and a lower molding cavity which define a cavity; the lower molding cavity is machined with a transverse support rib runner and a vertical support rib runner; the lower die is machined with an air vent; a temperature adjusting device is arranged on the lower die; and the casting runner consists of a main runner, a branch runner, a sprue and a cold slug well which are communicated with one another. The ABS plastic wire coil molding die fills up the blank of a phi-1100-type large ABS wire coil molding die; a manufactured phi-1100-type ABS wire coil is applied to an ABS bobbin and used in the tyre industry; the storage mount of materials is increased; a guarantee is provided for the aspect of design in terms of the strength; and the ABS plastic wire coil molding die is light in weight, durable, and neat and attractive in appearance.

Description

ABS plastic drum mould

Technical field

The utility model relates to the process units field of tire building equipment, at length is a kind of ABS plastic drum mould.

Background technology

As everyone knows, in the middle of the tyre production enterprise, the Φ 1100 type I-beam wheel that operations such as severing, zero degree and moulding are used all are irony I-beam wheel, weight is heavier, a dead lift is more painstaking, the ABS of drum manufacturing enterprise I-beam wheel moulding drum moulds all on the market are Φ 800 following specifications, in large-scale ABS I-beam wheel application facet, because large-scale ABS I-beam wheel complex manufacturing technology, the ratio of defects height, the limitation that load factor is wherein also arranged, large-scale I-beam wheel is made by the irony wheel, does not have Φ 1100 type specifications and above ABS drum mould product.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of existing large-scale drum plastics forming technique, a kind of ABS plastic drum mould is provided, filled up the blank of this large-scale ABS drum moulds of Φ 1100 types, the Φ 1100 type ABS drums of making are applied on the ABS I-beam wheel, concerned process steps at tyre industry is used, and has increased the storage of material, and is light durable, aesthetic appearance is strong, and has given the assurance of design aspect aspect intensity.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of ABS plastic drum mould, be provided with patrix and counterdie, it is characterized in that, the centre of patrix is processed with the cast runner, the periphery of patrix is processed with gathering sill, lead on gathering sill and the counterdie plugs together together, be processed with forming cavity on patrix and the counterdie respectively, the compacted under chamber, a unified die cavity is formed in last forming cavity and compacted under chamber, be processed with cross-brace muscle runner and longitudinal bracing muscle runner on the compacted under chamber, be processed with air discharge duct on the counterdie, temperature-adjusting device is installed on the counterdie, and the cast runner is by the sprue that is interconnected, runner, cast gate and cold slug well are formed.

The beneficial effects of the utility model are, filled up the blank of this large-scale ABS drum moulds of Φ 1100 types, the Φ 1100 type ABS drums of making are applied on the ABS I-beam wheel, use at tyre industry, increase the storage of material, and aspect intensity, given the assurance of design aspect and the application of production aspect.

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the utility model is provided with patrix and counterdie, the centre of patrix is processed with cast runner 2, the periphery of patrix is processed with gathering sill 3, lead 8 on gathering sill 3 and the counterdie plugs together together, gathering sill 3 and lead 8 can be guaranteed the accurate centering of upper die and lower die energy when matched moulds, be processed with forming cavity 1 on patrix and the counterdie respectively, compacted under chamber 7, last forming cavity 1 and compacted under chamber 7 die cavity 6 that forms a whole, be processed with cross-brace muscle runner and longitudinal bracing muscle runner on the compacted under chamber, by cooperating with extruder, ABS plastic drum injection moulding in die cavity 6 of I-beam wheel, cross-brace muscle runner and longitudinal bracing muscle runner are beneficial to hot melting plastic flowing in mould.Be processed with air discharge duct 5 on the counterdie, in order to the gas of die cavity in the forming process 6 is fully got rid of.Temperature-adjusting device 4 is installed on the counterdie, and cast runner 2 is made up of the sprue that is interconnected, runner, cast gate and cold slug well, and cast runner 2 is one group of feeding-passage of plastic melt being guided into die cavity 6 by the injector nozzle.In order to satisfy the requirement of injection technique to mold temperature, the temperature that needs 4 pairs of moulds of temperature-adjusting device is regulated.For the thermoplastic injection mould, mainly be that the design cooling system makes mold cools down.The way commonly used of mold cools down is to offer cooling-water duct in mould, utilizes the cooling water that circulates to take away the heat of mould.

Claims

1. ABS plastic drum mould, be provided with patrix and counterdie, it is characterized in that: the centre of patrix is processed with the cast runner, the periphery of patrix is processed with gathering sill, lead on gathering sill and the counterdie plugs together together, be processed with forming cavity on patrix and the counterdie respectively, the compacted under chamber, a die cavity is formed in last forming cavity and compacted under chamber, be processed with cross-brace muscle runner and longitudinal bracing muscle runner on the compacted under chamber, be processed with air discharge duct on the counterdie, temperature-adjusting device is installed on the counterdie, and the cast runner is by the sprue that is interconnected, runner, cast gate and cold slug well are formed.
