Technical Field

The invention relates to the technical field of dies, in particular to a die for extruding a PVC plate.

Background

The PVC plate is a vacuum plastic film and is used for surface layer packaging of various panels, so the PVC plate is also called as a decorative film and an adhesive film and is applied to various industries such as building materials, packaging, medicines and the like. The PVC board has the characteristics of water resistance, flame retardance, acid and alkali resistance, moth prevention, light weight, heat preservation, sound insulation, shock absorption and the like, is an ideal substitute for wood, aluminum and composite boards, and has a wide application range. At present, the notched mould is all adopted in most of the mould of extrusion PVC panel, adopts compression equipment to carry out extrusion to the raw materials, but because liquid hot raw materials has more heat, when the heat can't in time be discharged, panel shaping time is longer, and takes out in the notched mould is also difficult to follow to fashioned panel.

Disclosure of Invention

The invention aims to solve the defects in the prior art and provides a die for extruding a PVC plate.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a mould of extrusion PVC panel, includes compression side pipe and limiting plate, the supporting leg has all been welded in the bottom four corners of compression side pipe, the welding has the pipe of expanding on the outer wall of compression side pipe top one side, and expands the welding of material pipe top and have the feeder hopper, one side outer wall of feeder hopper is equipped with the level indicator down, the welding of the top outer wall of compression side pipe has the cooling tube, and the welding of the bottom outer wall of compression side pipe has the cooling tube, one side inner wall of compression side pipe is equipped with the spout, the slider has all been welded to the both sides outer wall of limiting plate, limiting plate one side outer wall is equipped with the through-hole, and the through-hole inner wall is pegged graft and is had the round pin axle, the opposite side inner wall of.

Preferably, the bottom of the supporting leg is bonded with a non-slip mat, and the surface of the non-slip mat is provided with non-slip threads.

Preferably, a sieve plate is welded at the joint of the material expansion pipe and the compressed square pipe.

Preferably, the cooling pipes are distributed in a serpentine shape, and circulating cold water is introduced into the cooling pipes.

Preferably, the diameter of the sliding block is matched with the diameter of the inner wall of the sliding groove, and the sliding block is in sliding fit with the sliding groove.

Preferably, the diameter of the inner wall of the compression square tube is matched with that of the compression block, and the outer wall of the compression block is bonded with a sealing ring.

The invention has the beneficial effects that:

1. the sieve that adopts in this design, can be effectual with the even distribution of hot dissolved liquid material to compression side intraduct, solved in the past compression process raw materials uneven distribution lead to the compression product problematic condition, and compression side pipe one side is equipped with can gliding limiting plate, when the product shaping after, take out limiting plate extrusion compression piece, can be convenient deviate from the product from the mould.

2. In the mould of this design's extrusion PVC panel, top and bottom outer wall at compression side pipe all are equipped with the cooling tube, and it can take away a large amount of heats in the compression process for the product can effectively cool down, has avoided product shaping back in the past, because the high temperature leads to the product softer, can lead to the condition that the product warp when placing imperfectly.
