specific Embodiment approach 1

[0007] Specific implementation mode one: combine Figure 1 ~ Figure 3 Describe this embodiment, this embodiment is made up of upper die and lower punch; Said upper die is made up of stripping bar 1, upper template 2, concave bottom die 3, upper die heating sleeve 4, spiral heating tube 5, concave The mold cover 6 is composed of; the spiral heating tube 5 is arranged in the side wall of the upper mold heating jacket 4 along the axial direction and is integrated with the upper mold heating jacket 4, and the two ends of the spiral heating tube 5 are exposed on the upper mold heating jacket 4 outside, the upper end surface of the upper mold heating jacket 4 is affixed to the lower end surface of the upper mold plate 2, the upper mold heating jacket 4 is equipped with a concave mold cover 6, the concave mold cover 6 is equipped with a concave bottom mold 3, and the upper mold heating jacket 4 The gap fits between the inner wall and the outer wall of the die cover 6, and the heating...

specific Embodiment approach 2

[0008] Specific implementation mode two: combination figure 1 To illustrate this embodiment, the lower end of the stripping rod 1 in this embodiment is provided with an external thread, and the lower end of the stripping rod 1 is threadedly connected with the concave bottom mold 3 . With such arrangement, the structure is simple, the connection is reliable, and it is easy to disassemble. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0009] Specific implementation mode three: combination figure 2 To describe this embodiment, a group of axial exhaust through-holes 14 in this embodiment are evenly distributed along the circumferential direction of the side wall of the die casing 6 . Such an arrangement can ensure that the steam generated by heating the wet billet is evenly discharged along a group of axial exhaust through holes 14 . Other components and connections are the same as those in the first embodiment.

Abstract

The invention relates to a pulp moulding external-shaping internal gasbag thermal-shaping die, and relates to a pulp moulding die, which aims at the problem that the existing pulp moulding die can not be prepared as a straight-cylindrical paper moulding tank. A spiral heating pipe is arranged inside the side wall of an upper die heating sleeve which is internally provided with a concave die sleeve. The concave die sleeve is internally provided with a concave bottom die. A withdrawal rod is connected with the concave bottom die. The side wall of the concave die sleeve is provided with an axial exhaust through hole. The internal wall of the concave die sleeve is provided with an exhaust gap which is communicated with the axial exhaust through hole. The axial exhaust through hole is communicated with a circular trough on an upper template. A supporting sleeve is fixedly connected with a lower blocking plate. A heat-resistance capsule is sleeved on the supporting sleeve and the lower blocking plate. The external diameter of the heat-resistance capsule is less than the internal diameter of the concave die sleeve. The supporting sleeve is internally provided with an electric heater and a radiator fan. A lower template and the lower blocking plate are provided with air inlets. The supporting sleeve is provided with an air outlet through hole. The die of the invention can be used for producing the straight-cylindrical pulp moulding tanks.

Description

technical field [0001] The invention relates to a pulp molding mold. Background technique [0002] In the pulp molding industry, the products made of pulp molding molds are mostly flat plates and bowls, and the vertical stretching distance does not exceed 20mm. If the stretching size is increased, the yield rate will be significantly reduced; if the stretching size exceeds 50mm, it will be difficult to make a product. Therefore the paper mold tank that adopts current pulp molding mold to make is actually a cone mold tank (that is, the tank wall has an inclination angle), which cannot be made into a straight cylinder shaped paper mold tank. Contents of the invention [0003] The purpose of the present invention is to provide a pulp molding outer shaping inner airbag heat setting mold, which can solve the problem that the existing paper pulp molding mold cannot be made into a straight cylinder shaped paper mold tank. [0004] The invention consists of an upper die and a lo...
