Description

Novel three-cylinder mould

Technical Field

The utility model relates to the technical field of mold, concretely relates to novel three jar moulds.

Background

The mould is various moulds and tools for obtaining required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production. In short, a mold is a tool for making a shaped article, this tool being composed of various parts, different molds being composed of different parts, which effect the processing of the shape of the article mainly by the change of the physical state of the material being shaped, and it is simply given the name "industrial mother".

In the casting process of a cylinder of an automobile engine, a water channel sand core is required to be added into a metal mold to form a cavity, the sand core is removed by a vibration shakeout machine after molding, so that a cooling water channel of the engine is formed at the original position for placing the sand core, the water channel sand core is generally made of phenolic resin and coated sand serving as raw materials through a shell core machine, and the water channel sand core is a water jacket sand core.

The existing mould is in a modular design and is combined with a sand core for use, but in the manufacturing process, the product forming speed is not well controlled, and the sand core and the mould are easy to damage when the mould is opened.

Therefore, how to upgrade the existing mold to overcome the above problems is a problem to be solved by those skilled in the art.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a be difficult to take place to damage during the side form mould drawing of patterns, and can control the novel three jar moulds of product shaping speed through the water-cooling.

In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a novel three jar moulds which characterized in that: including last mould, bed die, side form and cylinder, go up the mould with the bed die cooperation installation forms the mould main part, the bed die with it is provided with the installation breach to go up the mould both sides, it is provided with to slide in the installation breach the side form, the cylinder install in the mould main part outside, the cylinder is used for control the side form breaks away from the bed die, the inside chaplet that is provided with different shapes of side form, the chaplet includes U type chaplet and Y type chaplet, Y type chaplet is terminal to extend to both sides has supplementary chaplet, the chaplet is provided with the water-cooling passageway, the water-cooling passageway passes through two tops and external intercommunication of chaplet.

Specifically, go up the mould and include centre form and last external mold, the bed die includes centre form and lower external mold down, go up the centre form go up the external mold down the centre form down the external mold with gap between the side form forms the die cavity, go up the centre form with go up the external mold and down the centre form with connect through the locating pin between the external mold down, still be provided with many ejector pin through-holes on the bed die.

As an improvement, a fixing edge extends from the part of the side die, which is positioned outside the die main body, to the periphery, and the fixing edge is used for limiting the position of the side die.

Compared with the prior art, the utility model has the advantages of: divide into the mould main part into mould, bed die, side form three part, make the more convenience of die sinking after the product shaping, can not damage the product, for increasing die sinking efficiency, side form and last mould and bed die sliding connection, and install the cylinder in the outside, make it can drive the side form, pull out the side form, then open the top die, can take out the product, but after the product shaping, combine comparatively closely between the mould, consequently take place to damage easily when pulling out the side form, make the side form remain in the mould main part, therefore, add inside the core support of establishing of side form, ensure the structural strength of side form, the inside water-cooling passageway that is provided with of core support, the both ends of water-cooling passageway communicate with the external world, make it can circulate the cooling, control the speed of product cooling shaping.

Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

In the description of the present invention, it should be noted that, for the orientation words, if there are terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., the orientation and positional relationship indicated are based on the orientation or positional relationship shown in the drawings, and only for the convenience of describing the present invention and simplifying the description, it is not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and not be construed as limiting the specific scope of the present invention.

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1-2, the utility model discloses a preferred embodiment includes mould 1, bed die 2, side form 3 and cylinder 4, it forms the mould main part to go up mould 1 and 2 cooperation installations of bed die, bed die 2 and 1 both sides of last mould are provided with installation breach 5, it is provided with side form 3 to slide in the installation breach 5, mould main part modularization, can make up and change according to the demand, when some mould damages, can reduce the replacement cost, cylinder 4 installs in the mould main part outside, cylinder 4 is used for controlling side form 3 and breaks away from bed die 2, increase the die sinking efficiency, the inside chaplet that is provided with different shapes of side form 3, a structural strength for increasing side form 3, when preventing the drawing of patterns, it is too inseparable to connect between the mould. The side die 3 is broken, the chaplet comprises a U-shaped chaplet 32 and a Y-shaped chaplet 31, the tail end of the Y-shaped chaplet 31 extends to two sides to form an auxiliary chaplet 33, the chaplet is provided with a water cooling channel 34, and the water cooling channel 34 is communicated with the outside through two top ends of the chaplet, so that the water cooling channel can be circularly cooled, and the forming speed of a product is controlled.
