Description

A foaming mold with air-permeable holes and anti-overflow function

Technical Field

The utility model belongs to the technical field of foaming moulds, and in particular relates to a foaming mould with air holes and the function of preventing material overflow.

Background Art

Polyisocyanurate pipe shells and fittings are a kind of deep-cold conventional materials formed by block cutting and processing. As an intermediate semi-finished product, the quality of block directly affects the subsequent products. Generally, polyisocyanurate block foam is produced by fixed molds through injection, foaming, curing and curing, and the quality of block foam is affected by factors such as temperature, pores, and mixed air pressure.

During the foaming process of the block foam, polyisocyanurate will undergo a chemical reaction to generate a large amount of gas. If these gases are allowed to flow inside the block foam, high pressure will be generated inside the block foam, which may produce blocks with uneven density or cause the block foam to explode. Therefore, in order to make the pores inside the block foam evenly distributed and ensure the safety of the block foam production process, existing molds usually use a simple top opening as a gas passage. However, the foaming material will overflow, resulting in the inability to exhaust the gas, which not only pollutes the foaming mold but also affects the processing process.

Utility Model Content

In order to solve the problems in the related art, the present application provides a foaming mold with air holes to prevent material overflow, which solves the problems of foaming material overflow and gas failure to be completely discharged.

The technical solution is as follows:

A foaming mold with air holes to prevent overflow, comprising a mold shell and a cover plate arranged on the top of the mold shell, wherein a ventilation plate is attached to one side of the cover plate close to the mold shell, the ventilation plate is a plastic ventilation plate, and a plurality of ventilation holes are evenly distributed on the plastic ventilation plate.

Through the above technical scheme, by setting up the plastic ventilation plate, due to its simple structure, it only needs to be applied to the inner surface of the upper cover plate. Multiple ventilation holes can be set on the plastic ventilation plate to form a gas passage layer, thereby greatly improving the gas discharge efficiency; in addition, it can also be cut according to the actual size of the mold shell, and the plastic texture is easy to cut, so it can be applied to foaming molds of different sizes, expanding its application range.

Furthermore, the length value of the plastic vent plate is not less than the length value between the inner walls of the mold shell, the width value of the plastic vent plate is not less than the width value between the inner walls of the mold shell, the length value of the cover plate is consistent with the length value between the outer walls of the mold shell, and the width value of the cover plate is consistent with the width value between the outer walls of the mold shell.

Furthermore, a plurality of universal wheels with the same structure are evenly distributed on the bottom of the mold shell.

Through the above technical solution, through the setting of the universal wheel, when the foaming mold needs to be used, it can be quickly and conveniently moved to the specified position using the universal wheel. Product production can be carried out after only fixing the universal wheel. The structure is simple, which can save preparation time before product processing, thereby speeding up production efficiency.

Furthermore, a plurality of positioning holes with the same structure are evenly distributed along the top periphery of the mold shell; a plurality of positioning columns with the same structure are evenly distributed along the periphery of one side of the cover plate where the plastic ventilation plate is arranged, and the positioning columns and the positioning holes are arranged correspondingly and are compatible with each other.

Through the above technical solution, by setting the positioning holes and the positioning columns, the assembly and disassembly process can be made more stable and faster, thereby saving production time and improving production efficiency.

In summary, the beneficial effects of a foaming mold with air-permeable holes and anti-overflow function are:

1. Through the setting of the plastic vent plate, due to its simple structure, it only needs to be attached to the inner surface of the upper cover plate. Multiple vent holes can be set on the plastic vent plate to form a gas passing layer, thereby greatly improving the gas discharge efficiency; in addition, it can also be cut according to the actual size of the mold shell, and the plastic texture is easy to cut, so it can be applied to foaming molds of different sizes, expanding its application range;

2. Through the setting of the universal wheel, when the foaming mold needs to be used, it can be quickly and conveniently moved to the designated position by using the universal wheel. The product production can be carried out after the universal wheel is fixed. The structure is simple, which can save the preparation time before product processing, thereby speeding up production efficiency;

3. By setting the positioning holes and positioning columns, the assembly and disassembly process can be made more stable and faster, thereby saving production time and improving production efficiency.

It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.
