Description

Technical Field

[0001] The utility model relates to the technical field of PVC plastic ball valve moulds, in particular to a high-pressure PVC plastic ball valve mould. Background Art

[0002] PVC plastic ball valve mold is a mold tool used to produce PVC plastic ball valves. It is made of metal materials, usually high-strength and wear-resistant materials such as steel or aluminum alloy. These molds usually have complex internal structures to achieve various shapes, apertures and connection methods of PVC ball valves.

[0003] When demolding the existing high-pressure PVC plastic ball valve injection mold, it is necessary to move the upper mold plate and the upper mold base upward and then move the mold core alone to expose the high-pressure PVC plastic ball valve components formed in the mold core for demolding. The operation is relatively cumbersome, resulting in poor demolding convenience of the high-pressure PVC plastic ball valve mold.

[0004] The Chinese utility model patent currently announced as: CN218948318U discloses a high-pressure PVC plastic ball valve mold, which is provided with a lower mold base, a support plate, a lower mold plate, a mold core, an upper mold plate, an upper mold base, a pouring channel, a mounting hole, an inclined rod, a jack and an anti-slip block. When in use, molten PVC plastic is injected into the mold core through the pouring channel. After the molten PVC plastic enters the mold core, it can form the shape of a ball valve. After waiting for the PVC plastic in the mold core to cool and form, the upper mold base and the upper mold plate are pulled to move upward. The upper mold base and the upper mold plate drive four inclined rods to move upward. The four inclined rods drive two clamping plates on the mold core to move, so that the two clamping plates can be separated from the mold core, completing the separation of the mold core, so that the ball valve component in the mold core can be taken out, and the demolding of the injection mold is completed. Compared with the existing high-pressure PVC plastic ball valve mold, the demolding of this utility model is more convenient, which effectively improves the convenience of using the high-pressure PVC plastic ball valve mold.

[0005] In view of the above problems, the existing patent provides a solution, but in the process of use, it lacks the function of automatically pushing out the formed PVC plastic ball valve. After the PVC plastic ball valve is formed in the mold, it has a high temperature. Allowing it to cool down naturally in the mold will affect the subsequent work efficiency. If it is taken out after molding, the high temperature will cause harm to the staff.

[0006] Therefore, a high pressure-bearing PVC plastic ball valve mold is proposed. Utility Model Content
