Description
Technical Field
The utility model belongs to the technical field of the mould, concretely relates to vacuum tube mould.
Background
The vacuum tube mold is a special mold for injection molding of a PVC insulating sleeve, and the main production principle is as follows: firstly, injecting the mixture into a cavity of a mold for product molding, and sucking air to the outside of the cavity in the molding process so as to control the shape of a product, so that the sealing property of the mold is important; and traditional vacuum tube mould all adopts AB glue to scribble the mid portion that mould and seal shell guarantee the leakproofness of mould, but this kind of mode has very big defect, paints AB glue at first and needs manual seal, makes mistakes easily, and the leakproofness can not leak gas inadequately, leads to PVC insulation support production size unstability, uses glue to paint simultaneously, and seal shell is very inconvenient when the dismouting, consuming time power.
Therefore, there is a need to design a vacuum tube mold to solve the above technical problems.
Disclosure of Invention
In order to overcome the defects in the prior art, the utility model aims to provide a vacuum tube mould.
In order to achieve the above objects and other related objects, the present invention provides a technical solution: a vacuum tube mould comprises a mould body, wherein the mould body is cylindrical, a cavity is arranged in the center of the mould body in a separated mode, and the cavity is also cylindrical; the die body is provided with an air suction hole which is communicated with the cavity; a cylindrical sealing shell is sleeved outside the die body, a vent hole is formed in the sealing shell, and the vent hole is connected with an external air pump; the upper and lower parts of the die body are provided with two annular grooves, sealing rings are arranged in the annular grooves, the sealing rings are arranged in the middle parts of the die body and the sealing shell, and the die body is further provided with a cooling pipeline.
Preferably, the number of the air suction holes is a plurality, and the air suction holes are uniformly distributed on the circular curved surface of the die body.
Preferably, the middle part of the circular curved surface of the die body is provided with a groove, the upper end and the lower end of the circular curved surface of the die body are raised, the plurality of air suction holes are uniformly arranged in the groove, and the two sealing rings are arranged on the raised parts at the upper end and the lower end of the die body.
Preferably, the number of the cooling pipelines is several, and the several cooling pipelines are uniformly distributed around the die cavity in a circle.
The structural features of the above solution are explained as follows:
the vacuum tube mould of this scheme design is used for producing PVC insulation support's special mould, and is different with traditional vacuum tube mould, and this scheme adopts the sealing washer to replace AB glue, improves the holistic leakproofness of mould effectively, and it is more convenient that the sealed shell is changed in the dismouting simultaneously, and fashioned PVC insulation support size is also more stable.
The air suction holes are uniformly distributed, so that when air is sucked in the cavity, the air suction is ensured to be uniform, and the PVC insulating sleeve is more stable to form.
Set up flutedly in the circular curve mid portion of mould body, can reserve some spaces between mould and the seal shell like this for when breathing in deposit gaseous, if the space between mould mid portion and the seal shell is less, can lead to atmospheric pressure to increase, produce the condition of gas leakage easily.
The cooling pipeline is internally communicated with cold water, the main effect is to cool the product in the cavity, so that the product is rapidly molded, a plurality of cooling pipelines are uniformly distributed around the cavity, the uniformity of cooling is ensured, and the molding of the product is more stable.
The utility model has the advantages that: simple structure, the leakproofness is good, and sealed shell easy dismounting after using the sealing washer, labour saving and time saving, fashioned PVC insulation support size is also more stable simultaneously, has very high practical value.
