Abstract

The utility model discloses a rubber sole vulcanization mold without degating. The mold includes a mold cover core with a mold cover and a mold side wall with a mold cavity, wherein a cover core protruded tooth is arranged on the periphery of a transition end of the mold cover core and the mold cover; and a side wall chamfer is arranged on the periphery of an inner port of the mold side wall. When a rubber sole is vulcanized, the joint of gating glue and the rubber sole becomes the thinnest point under the action of the mold cover core protruded tooth and the mold side wall inner port, so that after the product is released from the mold, the product can be torn off from the gating glue along the edge of the rubber sole, the efficiency is improved, and the product quality is ensured.

Description

A kind of rubber soles sulfurizing mould that does not need to cut the mouth of a river

Technical field

The utility model relates to a kind of rubber soles sulfurizing mould, particularly a kind of rubber soles sulfurizing mould that does not need to cut the mouth of a river.

Background technology

Traditional rubber soles sulfurizing mould comprises the mould cover core with die cover, with the mould abutment wall that has die cavity.Therefore, in the production process, the unnecessary sizing material of filling under high pressure can overflow from the junction of mould and cover plate, forms mouth of a river glue.Moulding is that sole needs artificial or machinery prunes away and can come into operation behind the glue of the mouth of a river.So both wasted manpower, lost the energy again, and often caused product to cut wound in the pruning process, and caused damage and waste.Moreover though manually prune relatively safety, inefficiency has improved efficient though machinery is pruned, and there is risk in mechanically actuated, causes personal injury easily.

Summary of the invention

The purpose of this utility model is exactly at above-mentioned situation, and a kind of sulfurizing mould that need not cut mouth of a river glue is provided.This mould only needs can easily tear mouth of a river glue with have gentle hands is light once drawing when depanning, and product need not to prune and just can come into operation, efficient, safety.

Technical solution of the present utility model is: a kind of rubber soles sulfurizing mould that does not need to cut the mouth of a river comprises the mould cover core with die cover plate, with the mould abutment wall that has die cavity; Wherein the periphery at the transitioning end of described mould cover core and die cover 1 has the cover core double wedge; Then described mold side within the walls the periphery of port be provided with the abutment wall chamfering.When rubber soles is vulcanized, in mould cover core double wedge and mold side within the walls under the effect of the abutment wall chamfering of port, make the junction of mouth of a river glue and rubber soles form the weak spot of thickness.After the product depanning, thereby mouth of a river glue is come along the fracture of rubber soles edge.

According to These characteristics, described abutment wall chamfering is 30 °--45 °.

In a word, a kind of rubber soles sulfurizing mould that does not need to cut the mouth of a river that the utility model provides, because of the periphery of the transitioning end that adopted mould cover core and die cover has the cover core double wedge, with mold side within the walls port peripheral tool have the abutment wall chamfering to install to cooperate, so just guaranteed in the sulfidation, unnecessary sizing material is flowed out along the slit between mould and the cover plate, through high temperature vulcanized formation mouth of a river glue, formed thickness less than the weakest point of 1mm with the junction of rubber soles, after the demoulding, directly disconnect along the rubber soles marginal laceration with pulling moving mouth of a river glue, convenient and swift, product can directly come into operation, saved follow-up pruning operation, save manpower and device resource, improved efficiency, reduced cost.Simultaneously, mouth of a river glue section is level and smooth, neat, has improved product quality.

The specific embodiment

Below in conjunction with accompanying drawing embodiment to this novel being described further.

See Fig. 1, a kind of rubber soles sulfurizing mould that does not need to cut the mouth of a river shown in Figure 2, have on the basis of original mould abutment wall 4 and increase 3mm, and tilt laterally 45 ° to constitute abutment wall chamfering 5 apart from mould internal orifice 2mm place above it, like this, mouth of a river glue 8 outside abutment wall chamfering 5 parts of rubber soles 7 have formed certain space, make mouth of a river glue 8 herein increase thickness, formed certain intensity.Increase 3mm at the transitioning end of mould cover core 2 and die cover plate 1 and formed cover core double wedge 6, it is characterized in that when the mould abutment wall increases 3mm, mould cover core 2 thickness have also increased 3mm, for above-mentioned improvement and the constancy of volume of die cavity 3, the both shape of sole and constancy of volume.In the present embodiment, up and down during the mould matched moulds, utilize the cover core double wedge 6 on the mould cover core 2 of mold, and form the triangle gap between the abutment wall chamfering 5 of mould abutment wall 4 inner port of bed die.Promptly the rubber soles after the sulfuration 7 is the thinnest with the thickness of the binding site of mouth of a river glue 8.

In process of production, after the mould closure of interpolation sizing material, under the effect of high pressure, unnecessary sizing material is flowed out, along the slit between die cover plate 1 and the mould abutment wall 4 through high temperature vulcanized formation mouth of a river glue 8.Under the effect of chamfering 5 on the mould abutment wall 4, mouth of a river glue 8 thickness of upper end are increased, thus strong certain intensity.On the contrary, under the effect of mould cover core double wedge 6, make the mouth of a river glue 8 and the junction of rubber soles 7 form thickness less than the weakest point of 1mm.After the product depanning, with pulling moving mouth of a river glue 8, because the edge stress of mouth of a river glue 8 and rubber soles 7 just concentrates on the weakest binding site of mouth of a river glue 8 and rubber soles 7,, thereby mouth of a river glue 8 is come along the fracture of rubber soles edge because rubber has the characteristic of hot tear crack.

Claims

1. a rubber soles sulfurizing mould that does not need to cut the mouth of a river comprises the mould cover core with die cover, has the mould abutment wall that has die cavity; It is characterized in that, have cover core double wedge (6) at the periphery of the transitioning end of described mould cover core (2) and die cover (1); Then the periphery in described mould abutment wall (4) inner port is provided with abutment wall chamfering (5).

2. the rubber soles sulfurizing mould that does not need to cut the mouth of a river according to claim 1 is characterized in that, described abutment wall chamfering is 30 °--45 °.
