Description

Wire casing design mould

Technical Field

The utility model relates to a wire casing mould technical field, more specifically relates to a wire casing design mould.

Background

The wire casing is used for arranging wires such as power lines, data lines and the like in a standard mode and fixing the wires on a wall or a ceiling, and the conventional wire casing comprises a metal wire casing and a PVC wire casing. The PVC wire casing is manufactured by cooling and shaping through entering a PVC wire casing mould through PVC molten material, and in the existing wire casing mould, the lower surface of a panel fixed cavity is a flat plane, so that in the shaping process of the wire casing mould, due to various factors such as cooling, shrinkage, matching or overlapping and the like, the surface or the bottom of most wire casing products are uneven and sunken, particularly large-size products seriously affect the appearance of the products, and the quality of the products is unqualified.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome current wire casing mould and cause the shortcoming of the uneven sunken in wire casing product bottom surface or surface at the design in-process, provide a linear type design mould. The utility model discloses can make the wire casing surfacing of stereotyping, the wire casing outward appearance is square.

In order to solve the technical problem, the utility model discloses a technical scheme is: a wire casing design mould, wherein, includes first mould piece, medium plate and second mould piece, the medium plate is sandwiched between first mould piece and second mould piece. In this technical scheme, first mould piece is stereotyped the bottom of wire casing, and second mould piece is stereotyped the face lid of wire casing.

Furthermore, the first mold block comprises a first hollow plate, a bottom plate and a first insert, the bottom plate is embedded in one side, facing the middle plate, of the first hollow plate, the first insert is clamped between the bottom plate and the middle plate, and a bottom cover fixing cavity of the bottom cover is formed between the first insert and a bottom cover fixing groove formed in the bottom plate. The second mold block comprises a second hollow plate, a panel and a second insert, the panel is embedded in one side, facing the middle plate, of the second hollow plate, the second insert is clamped between the panel and the middle plate, and a fixing cavity of the face cover is formed between the second insert and a face cover fixing groove formed in the panel. The periphery of the bottom cover shaping groove is arranged to be inclined and symmetrical outwards, and the bottom surface of the surface cover shaping groove is arranged to be an arc surface.

In the technical scheme, PVC molten materials are cooled and shaped for the slot bottom cover in a bottom plate shaping cavity formed between a bottom plate and a first insert, and the periphery of a bottom cover shaping groove is provided with inclined edges which are obliquely and symmetrically outwards, so that after the slot bottom cover is shaped, two sides of the slot bottom cover are provided with inclined edges with a certain angle; the cooling of wire casing face lid is stereotyped in the panel die cavity that the PVC melt formed between panel and second mold insert, and the bottom surface of face lid design recess is established to the arc surface, so its capping is the arc shape behind the sizing of wire casing face lid, because wire casing face lid and bottom after the drawing of patterns, both further cool off and cooperate or stack, lead to the further shrink deformation of two hypotenuses of wire casing face lid and wire casing bottom circular arc capping, wire casing face lid and wire casing bottom become a positive product, thereby avoid the face lid of wire casing to produce the concave surface owing to shrink deformation in later stage.

Further, a bottom plate cooling water pipeline is arranged inside the bottom plate. And a panel cooling water pipeline is arranged inside the panel. Cooling water flows through the bottom plate cooling water pipeline, and the cooling water takes away the heat of the PVC molten material in the bottom plate fixed cavity, so that the PVC molten material is cooled and shaped in the bottom plate fixed cavity to form a wire slot bottom cover; the same circulation cooling water among the panel cooling water piping, the heat of PVC melt at the panel die cavity is taken away to the cooling water for the PVC melt cools off in the panel die cavity and stereotypes, forms wire casing face lid.

Furthermore, first hollow plate inside is equipped with first hollow chamber, the second hollow plate inside is equipped with second hollow chamber, first hollow chamber with all be equipped with the connector of being connected with the air pump on the second hollow chamber. The bottom plate is internally provided with a first air groove, one end of the first air groove is communicated with the first hollow chamber, and the other end of the first air groove is communicated with the shaping cavity of the bottom plate. The panel is internally provided with a second air groove, one end of the second air groove is communicated with the second hollow chamber, and the other end of the second air groove is communicated with the shaping cavity of the panel. The width range of the first air groove and the second air groove is 0.5mm-1.5 mm. The connecting hole of the first hollow chamber is connected with an air pump, the air pump extracts air from the first hollow chamber, and the first air groove communicates the first hollow chamber with the bottom plate shaping cavity, so that when the air pump extracts air from the first hollow chamber, the air extraction is also performed on the bottom plate shaping cavity communicated with the first air groove, and an adsorption force is generated, so that a PVC (polyvinyl chloride) melting material can be tightly attached to the surface of the bottom plate shaping cavity; connecting hole and air pump on the second cavity room are connected, the air pump carries out gaseous extraction to second cavity room, the second air duct is stereotyped the chamber with second cavity room and panel and is communicate, so when the air pump carries out gaseous extraction to second cavity room, also carry out the panel of intercommunication to second air duct and decide the die cavity and carry out gaseous extraction, produce the adsorption affinity, make the PVC melt can hug closely on the surface of deciding the die cavity at the panel, the heat of PVC melt can fully be taken away to the inside cooling water piping of panel, make the line casing face lid cool off the design better. Because the width in first gas tank and second gas tank is little, and PVC melt tension is big, can cool off the design rapidly when touch panel and bottom plate, so carry out the in-process that gas was extracted at the air pump, the PVC melt can not flow into in first gas tank and the second gas tank.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model changes the shapes of the shaping cavities of the bottom plate and the panel, so that the shaped slot bottom cover and the shaped slot face cover are further cooled at the later stage, and when the slot bottom cover and the shaped slot face cover are matched or stacked, the situation that the surface of the slot is sunken and uneven in the later-stage shrinkage deformation can be avoided; through the cooperation of air duct and cavity for the bottom plate can be hugged closely to the PVC melt and panel is decided the die cavity internal surface and is cooled off the design.
