Abstract
The utility model relates to an expansion device of a foaming mould. The expansion device comprises a mould base, a mould core, an ejection plate and an air cylinder, wherein the mould base comprises a base seat and a guide seat; the guide seat is arranged on the base seat; the outer side surface of the guide seat is a conical surface; the mould core is elastic and comprises a top mould part and a side mould part; the side mould part is annular, the inner side surface of the side mould part is a conical surface matched with the outer side surface of the guide seat, and the side mould part is arranged on the outer side of the guide seat and is in slide fit with the guide seat; the top mould part is connected to the top of the side mould part; a containing hole is formed in the mould base; the ejection plate is arranged in the containing hole and matched with the containing hole, and props against the lower surface of the top mould part; the air cylinder is arranged in the containing hole, and one end of the air cylinder is connected with the ejection plate to drive the ejection plate to move up or down. According to the expansion device provided by the utility model, the demoulding operation is easier as the mould core can be contracted during demoulding.
Description
Technical field
The utility model relates to refrigeration plant and manufactures field, especially relates to a kind of foaming mould device that expands.
Background technology
When manufacturing the equipment such as refrigerator, conventionally need to use various moulds, wherein foaming mould is wherein a kind of conventional mould.But existing foaming mould is comparatively difficult when the demoulding, needs very complicated mould emptier carry out the demoulding, causes die cost higher.
Utility model content
The purpose of this utility model is for the problems referred to above, and a kind of foaming mould of the easy demoulding device that expands is provided, and has solved the existing technical problem of prior art.
For achieving the above object, the utility model has adopted following technical proposal: a kind of foaming mould device that expands, it comprises die holder, core rod, top board and cylinder, described die holder comprises base and guide holder, described guide holder is arranged on described base, the outer surface of described guide holder is the conical surface, described core rod has elasticity, it comprises backform portion and side form portion, described side form portion ringwise, and its inner surface is the conical surface matching with the outer surface of described guide holder, described side form portion is arranged at the outside of described guide holder, be slidably matched with described guide holder, described backform portion is connected to the top of described side form portion, on described die holder, offer accepting hole, described top board is arranged in described accepting hole, and match with described accepting hole, described top board supports the lower surface of described backform portion, described cylinder is arranged in described accepting hole, and its one end is connected to drive described top board to move up and down with described top board.
At above-mentioned foaming mould, expand in device, preferably, on described guide holder, offer inclined ramp, in described side form portion, be provided with the first guide finger matching with described inclined ramp.
At above-mentioned foaming mould, expand in device, preferably, on described base, be formed with the locating platform that is positioned at described guide holder outside.
The foaming mould that the utility model the provides device that expands, owing to can making core rod shrink when the demoulding, therefore makes the demoulding become comparatively easy.
Accompanying drawing explanation
Fig. 1 is the expand structural representation of device of foaming mould of the present utility model.
The specific embodiment
Please refer to Fig. 1, the utility model embodiment provides a kind of foaming mould device that expands, and it comprises die holder 12, core rod 13, top board 15 and cylinder 14.
Die holder comprises base and guide holder 121, and guide holder 121 is arranged on base, and the outer surface of guide holder 121 is the conical surface.Core rod 13 has elasticity, and it comprises backform portion 131 and side form portion 132, and ringwise, and its inner surface is the conical surface matching with the outer surface of guide holder 121 in side form portion 132.Backform portion 131 is connected to the top of side form portion 132.Side form portion 132 is arranged at the outside of guide holder 121, is slidably matched with guide holder 121.
On die holder 12, offer accepting hole, top board 15 is arranged in accepting hole, and matches with accepting hole, and top board 15 supports the lower surface of backform portion 131.Cylinder 14 is arranged in accepting hole, and its one end is connected to drive top board 15 to move up and down with top board 15.
Because the outer surface of guide holder 121 and the inner surface of side form portion 132 are the conical surface of working in coordination, and core rod 13 has elasticity, therefore when the demoulding, top board 15 jack-up backform portion 131 upwards under the promotion of cylinder 14, there is a certain amount of contraction in core rod 13, therefore makes the demoulding become and be easy to.And when core rod 13 pressurizeds move down, 13 distending appropriate sizes of core rod.
In a preferred embodiment, on guide holder 121, offer inclined ramp 123, in side form portion 132, be provided with the first guide finger 133 matching with inclined ramp 123.Further, the top of guide holder 121 is provided with the second guide finger 124 straight up, offers the pilot hole matching with the second guide finger 124 in backform portion.
In a preferred embodiment, on base, be formed with the locating platform 122 that is positioned at guide holder 121 outsides.When core rod 13 presses to certain position, the bottom surface of side form portion 132 supports bit platform 122, realizes location.
The foaming mould that the utility model the provides device that expands, owing to can making core rod shrink when the demoulding, therefore makes the demoulding become comparatively easy.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although more used the terms such as die holder, core rod, top board and cylinder herein, do not got rid of the possibility of using other term.Use these terms to be only used to describe more easily and explain essence of the present utility model; They are construed to any additional restriction is all contrary with the utility model spirit.
