This kind mould is fit to the simple relatively insulating cylinder part of shape, and is the insulating cylinder of full skirt shape for complex contour, as profile, and traditional mould structure and release method not only make mould make difficulty, also demoulding taking-up product smoothly after the cast.
Summary of the invention:
The purpose of this invention is to provide a kind of full skirt shape insulating cylinder casting mold, its process is simple, and dress is convenient in demoulding, and can guarantee the insulating part quality.
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, a kind of insulating cylinder casting mold is provided, comprises following, the seat of honour, core rod and die sleeve, described die sleeve is fixed on down between the seat and the seat of honour, be provided with core rod in die sleeve inside, the seat of honour is provided with two cast gates; Fixedlying connected with the seat of honour in described core rod upper end, fits with following and seal with sealing ring in the lower end; Form casting space between described following, the seat of honour, core rod and the die sleeve, casting space all communicates with two cast gates.
Described die sleeve be by on insert, insert down and insert fixedly to pile up and form in the centre; Described die sleeve profile is a tubular, and the die sleeve inwall is a full skirt shape curved surface.
Insert on described and under insert and be semi-annular shape, its inwall one end has the umbrella shape projection; Insert and be semi-annular shape in described centre, its inwall one end has the umbrella shape projection; Insert and be the 1-5 piece in described centre.
Insert on described, insert down and insert and fix by long bolt and pin in the centre; Insert on described, insert down, the common die sleeve of forming is inserted in the centre.
The described seat of honour is provided with screw special, and this screw special is used for fixing inserts.
The threaded portion of described screw special is the ST screw thread.
Described two cast gates are symmetrical arranged.
The invention provides a kind of dies cavity edge and piece together structure, the concave and convex surface of mold cavity is converted into convex surface, make the processing of cavity surface be able to simple realization, have processing characteristics simple, easy to maintenance.
Type of the present invention adopts the mould steel mirror finish to handle, and has favorable surface quality, can satisfy the surface quality requirement of high-voltage switch gear part strictness.
Edge of the present invention is pieced together structure and is had the many places die joint, helps the exhaust of dies cavity depths.
The present invention adopts the special-purpose attachment screw of steel wire thread bush inserts, and is easy to use.
Advantage of the present invention is: a plurality of assemblies complicated, that can't the processed mould die cavity be converted into easy processing, easy-maintaining are simple in structure, help guaranteeing that parts quality, working service are convenient.

The specific embodiment:
Below in conjunction with accompanying drawing the present invention is done and to describe in further detail:
Referring to Fig. 1-6, a kind of insulating cylinder casting mold, the full skirt type inner chamber of this mold cavity is divided into the assembly of many simple die cavity edges and forms (Fig. 2), be specially a plurality of full skirts are severed from the top portion of each umbrella shape, former full skirt is partitioned into to be piled up by the single umbrella shape piece of multi-disc (Fig. 3) forms, each piece simple shape, thus the full skirt bottom that will cave in, be difficult for processing originally be converted into expose, the simple geometric shape, be convenient to mold cavity processing and surface finish.Be connected in one by pin location, bolt and nut between each piece.Whole die sleeve is divided into symmetrical two parts from axis, and weldering connecting plate in two parts junction seals with guide pillar guide pin bushing location, bolt and nut connection, rubber rope by connecting plate between two parts.Be to improve the inserts screw strength, the inserts screw thread adopts steel wire thread bush screw thread, and the mold insert dog screw is designed to the ST screw thread, can be directly with the steel wire thread bush with being threaded.
According to above technical scheme, have following characteristics: Mould Machining is convenient; Raw material pours into from the cast gate that is arranged at the upper end during cast, and rising head is set simultaneously, helps gas and discharges and order curing; Die sleeve laterally separates from the centre during demoulding, and insulating part full skirt profile is separated with mould inner wall, thus the demoulding smoothly; The aluminum inserts adopts steel wire thread bush screw thread, and ST screw thread screw special is used in its location, has increased the intensity of flush type inserts, and is easy to use.
As shown in Figure 1, the mould die sleeve is made up of two semicircular ring die sleeves, every half module is connected with pin by long bolt by 5 die sleeve pieces and combines an integral body, seal with sealing cord between the two semi-ring die sleeves, connect into a complete die sleeve by guide pillar, guide pin bushing and bolt and nut, the die sleeve and the seat of honour, following and core rod form mold cavity jointly, the metal insert that utilizes the screw special location of ST screw thread to imbed, and the seat of honour is provided with cast gate and rising head.
During cast, mould keeps flat, and injects by a cast gate and waters material feeding, waters material feeding filled-type chamber and consecutive solidification from bottom to top, and another cast gate is done rising head usefulness, in order to exhaust, fills with die cavity and overflows cast gate and rising head until watering material feeding.
Solidify the back demoulding, remove screw special, dismantle down seat, the seat of honour stay in the die sleeve pouring piece together with core rod; Left and right directions is opened die sleeve, can obtain product smoothly.
Above content is to further describing that the present invention did in conjunction with concrete preferred implementation; can not assert that the specific embodiment of the present invention only limits to this; for the general technical staff of the technical field of the invention; without departing from the inventive concept of the premise; can also make some simple deduction or replace, all should be considered as belonging to the present invention and determine scope of patent protection by claims of being submitted to.
