Automatic molding machine for producing pulp moulded products at super small draft angle

Abstract

The present invention discloses an automatic molding machine for producing pulp moulded products at a super small draft angle, being configured as such that when an overturn means is performing the action of overturning, a centralizing gear of a centralizing means supportively assists in the ascending or descending synchronous movements along a centralizing rack on a centralizing shaft rod so as to enable all shafts to ascend or descend to a defined position in a synchronous and parallel manner, when a pulp absorbing die is conducting up and down movement or overturning movement, due to the supportive assistance between the centralizing gear and the centralizing rack, which will facilitate the realization of a complete and correct die locking as the pulp absorbing die is driven ascended for die locking with an extrusion die, or is driven descended for die locking with a moving die. At the same time, the extrusion die has a descending stroke controlled by a power cylinder body so as to conduct die locking with the ascending pulp absorbing die, which will reduce the move stroke of the pulp die, reduce manufacturing man-hour and manpower, decrease manufacturing cost, and improve qualification rate and excellent quality rate and product competitiveness.

Description

【Technical field】 [0001] The present invention relates to an automatic molding machine for pulp molding products with an ultra-small draft angle, especially a kind of extrusion die that descends by a stroke to be molded with the pulp suction mold, and can make the pulp suction mold reach a fixed point. It is an automatic molding machine for pulp molding products with an ultra-small draft angle positioned to fit the extrusion mold correctly. 【Background technique】 [0002] In the early days, many industrial products and household products were made of plastic materials. Later research found that products made of plastic materials are easy to release toxins and cause serious pollution to the environment. It is difficult to recycle and reuse, or it is difficult to recycle and decompose. Recycling Problems such as huge costs, due to the huge amount of plastic products, have caused serious damage to environmental protection for many years. In today's era of rising environmental a...

Problems solved by technology

[0006] As far as the conventional molding machine for manufacturing molded products is concerned, the biggest deficiency is that the turning action of the turning mechanism is difficult to control, and sometimes the turning action may be over or under during the operation process; moreover, the up and down movement of the frame is Driven by external power (usually the power cylinder), there is no other mechanism to support the alignment during the stroke, so when the ascent or descent reaches a fixed point, there will be deviation and non-parallel situation of the suction mold, so that the suction mold will be driven When the lifting mold is closed with the extrusion mold, or when it is driven down and the moving mold is closed, the mold clamping is often not correct, and it is necessary to stop and then adjust

In addition to lowering the yield rate, this kind of improper mold clamping has the most direct impact on wasting man-hours and manpower, resulting in high manufacturing costs and improved real value.

[0007] In addition, in conventional molding machines for manufacturing molded products, the extrusion die is set at a fixed position above the inside of the main frame, and then the slurry suction die is moved upwards for a stroke to close the extrusion die so that the slurry Layer extrusion (pressing) is shaped into an initial product, so if the suction mold is calculated based on the initial position when it stops, the stroke of moving down into the pulp box and then returning upward is calculated. In addition, it is also necessary to calculate the stroke of moving upward to close the extrusion mold and then returning downward. That is to say, the conventional suction mold must carry out downward è upward è and then There is no way to reduce the itinerary of going up and down, resulting in a waste of man-hours and also causing high manufacturing costs. The same value is improved
