Description

TECHNICAL FIELD

[0001] The utility model relates to the mould field especially relates to a mould for processing the stopper of combustor. BACKGROUND

[0002] The combustor is the device that mixes and burns fuel and air in a certain way. The combustor is divided into industrial combustor, combustion machine, civil combustor and special combustor according to type and application field, and is usually made of stainless steel or metal titanium and other corrosion-resistant and high-temperature-resistant materials. The refractory stopper is added to the combustor to increase the refractoriness of the combustor and improve the service life of the combustor.

[0003] The refractory stopper of the combustor is usually processed by using a mould. The mould is a tool for shaping a blank (solid and liquid) into a workpiece with a certain shape and size under the action of external force.

The shell bottom of the box-shaped edge shell is provided with a through hole for the core block and the core rod to pass through. The edge shell is adaptively and telescopically arranged on the core mould.

[0007] The outer mould is a box-shaped structure that is permeable from top to bottom. The outer mould is tightly and telescopically arranged on the outer sidewall of the edge shell. The outer mould is placed on the bottom plate.

[0008] The edge shell and the bottom plate are arranged in an upper and lower spaced manner, or the edge shell is placed on the bottom plate.

[0009] The above-mentioned technical scheme has the beneficial effects that the core mould can support the required pattern inside the combustor. The core block is used for forming a ventilation channel, and the core rod is used for forming a gas pipeline and an ignition pipeline. The edge shell is telescopically arranged on the core mould. The combustor comprises the edge shell, which can serve as part of the stopper forming mould of the combustor. The combustor formed by using the mould can connect the edge shell and the support block together. Then, the whole demoulding can be realized by taking down the edge shell from the core mould. The pouring and demoulding of the whole combustor stopper are more convenient, and the manufacturing efficiency of the combustor stopper is improved.

[0010] Further, a support block is arranged between the bottom plate and the bottom of the side shell, the support block is symmetrically arranged in two groups along the front-rear direction, and the support block is located directly below the side shell, and a jacking mechanism is arranged at the interval between the side shell and the bottom plate, and the jacking mechanism is fixed on the bottom plate.

[0011] Beneficial effect: The support block can form an interval space between the bottom plate and the bottom of the side shell, facilitating jacking and demolding from this position.

[0012] Further, the core block comprises a first limiting block and a second limiting block, the first limiting block is fixed on the bottom plate, a slot is formed above the first limiting block, and the second limiting block is adapted to be inserted into the slot.

[0013] Beneficial effect: The second limiting block can reduce the height of the core block, thereby reducing the difficulty of bottom lifting demolding.

[0014] Further, the core block is arranged in two groups, and the two groups of core blocks are symmetric about the width direction of the bottom plate.

[0015] Beneficial effect: Corresponding to the two groups of ventilation channels after the burner is formed.

[0016] Further, a handle is arranged on the top of the second limiting block.

[0017] Beneficial effect: The second limiting block is conveniently taken out from above during demolding.

[0018] Further, the core rod comprises a first limiting rod and a second limiting rod, and the diameter of the first limiting rod is greater than the diameter of the second limiting rod.

[0019] Beneficial effect: The first limiting rod provides an access path for the ignition device after the burner is formed, and the second limiting rod is used for the gas inlet path.

[0020] Further, the second limiting rod is arranged in multiple groups along the length direction of the bottom plate.

[0021] Beneficial effect: It is convenient for the burner to use the gas to flow uniformly and enter.

[0022] Further, a lifting ring is arranged on the top of the side wall of the outer mold.

[0023] Beneficial effect: The outer mold is conveniently taken out from the upper part during demolding.
