Abstract

The utility model discloses a side-locked compound rubber extruder head. The side-locked compound rubber extruder head comprises an upper die body and a lower die body which are mounted on a frame, a middle die body between the upper die body and the lower die body, an upper die body locking mechanism and a lower die body locking mechanism, wherein a runner cavity is respectively formed between adjacent die bodies, the upper die body locking mechanism comprises an upper die body left locking oil cylinder and an upper die body right locking oil cylinder which are arranged on two sides of the upper die body and move synchronously in the opposite directions; the lower die body locking mechanism comprises a lower die body left locking oil cylinder and a lower die body right locking oil cylinder which are arranged on the two sides of the lower die body and move synchronously in the opposite directions; the piston rod of each locking oil cylinder is connected with a locking block, wedge-shaped surfaces compressing mutually during die assemblies of the die bodies are arranged between each locking block and the corresponding die body; and rubber gear pumps are arranged in positions, which correspond to the material extruding port of each runner cavity, on the back side of the frame, and each rubber gear pump is connected with a corresponding extruder. In the compound rubber extruder head, locking force of the upper die body, the lower die body and the middle die body is exerted from two side surfaces of the extruder head, and the structure of the rear part of the extruder head is simplified, the rubber gear pumps and a supporting machine frame for the rubber gear pumps can be mounted conveniently, and products formed through the extrusion of the extruder head are stable in pressure and dimension.

Description

Side locking compound rubber extrusion device head

(1) technical field:

The utility model relates to rubber manufacturing machinery, is specially a kind of side locking compound rubber extrusion device head.

(2) technical background:

Extruder is a kind of basic equipment of rubber industry, is one of key equipment that influences product quality, plays important effect in the production process of tire and rubber.

In the prior art (is example with two compound rubber extrusion device heads), the locking device of head is positioned at the rear portion of head, is in the two sides of extruder barrel, and the coupling mechanism force that locking cylinder produces will be locked a door by crossbeam and be strained backward, thereby with upper and lower mould and the locking of middle mould.

As the rubber gear pump will be increased, just need reserve the installation site of gear pump between extruder and complex extruder head.And intrinsic complex extruder group, extruder is to connect by the machine barrel flange with head, the locking device of head is installed in the rear portion of head, exactly because the head locking device stop that the rubber gear pump can't be installed on the hydraulic head.

(3) utility model content:

The purpose of this utility model is to propose a kind of structure of optimizing distribution, and is convenient to the side locking compound rubber extrusion device head of equipment I﹠M.

Can realize the side locking compound rubber extrusion device head of above-mentioned purpose, comprising is hinged be installed on the support on, lower mold body and last, middle die body between the lower mold body (different middle die body and last, can constitute two compound between the lower mold body, three compound or four compounded rubber extrusion device heads) and on, the lower mold body retaining mechanism, form flow passage chamber between the adjacent die body, different is described on, the lower mold body retaining mechanism comprises and being arranged at, the upper die body left side that the lower mold body both sides are synchronized with the movement in opposite directions, a right locking cylinder and a lower mold body left side, right locking cylinder, the piston rod of each locking cylinder connects latch segment, is provided with the lozenges that compresses mutually when the die body matched moulds between each latch segment and the corresponding die body.

Lozenges on the described die body is (being installed on the die body) removable wedge, by the replacing of the wedge that weares and teares in the locking process being stablized the coupling mechanism force of setting.

The lozenges of described wedge and the angle of horizontal plane are 3 °～9 °, and optimum angle is 5 °, 5.5 °, 6 °, 7 °.

In the said structure, upper and lower die body retaining mechanism is arranged at the support side, has simplified back structure behind the support, provides the space for corresponding to the crowded material mouth position of each flow passage chamber the rubber gear pump being installed on the support back side, and each rubber gear pump connects corresponding extruder.

Advantage of the present utility model:

The utility model side locking compound rubber extrusion device head has proposed a kind of new design, different with the locking mode of conventional composite machine head, the coupling mechanism force of the upper die body of composite machine head, lower mold body and middle die body applies from the head two sides, the head rear structure is simplified, the power set and the frames thereof of rubber gear pump can be installed easily, overcome the shortcoming of original technology, stablized the pressure of head extruded product, thereby improved the dimensional stability of extruded product.
