Description
Technical Field
The utility model relates to an EPS foam molding equipment, especially a preparation hotbed chives is planted and is softened mould demoulding mechanism for cover.
Background
The hotbed chives are also called as Chinese chives bud, Chinese chives bud and Chinese chives, are commonly called as Chinese chives white, and are products of the Chinese chives which are softened, cultivated and turned to be yellow. The leeks are completely grown in the dark by isolating light, and can not produce photosynthesis due to no sunlight supply, so that chlorophyll is synthesized and turns into yellow, which is called as "leek". In the planting and softening process of the chives, a cover body with light-shading property (a softening cover for short, made of common cement or PVC) is often used for covering the chives, so that the chives grow in a light-tight environment. However, the prior softening cover has the following disadvantages: the softening cover made of the cement is heavy and inconvenient to carry, is easy to crack due to falling or shaking in the carrying or transporting process, and has poor heat insulation performance and large temperature difference of the growing environment of the hotbed chives, so that the hotbed chives grow slowly; although the softening cover made of PVC is light, the heat insulation effect is poor, when the external temperature is 30 ℃, the temperature in the softening cover made of PVC can reach 50 ℃, hotbed chives growing in the softening cover can be easily scalded at the temperature, and besides, the softening cover made of PVC is easy to decompose toxic gas of hydrogen sulfide at the temperature, and the use is unsafe and environment-friendly. In order to overcome the problems, the applicant designs an EPS hotbed chives planting softening cover which has excellent light shading performance and heat insulation performance at the same time, provides an excellent environment for the growth of hotbed chives and improves the hotbed chives planting quality; in addition, the softening cover product is light in weight, strong in toughness and easy to transport and carry, and can be reused, so that the softening cover is more energy-saving and environment-friendly. The EPS hotbed chives planting softening cover is mainly manufactured by using an EPS foam molding die, the softening cover is demolded along the length direction after being molded in the manufacturing process, and the softening cover sometimes stays in a cavity of a female die after demolding due to the fact that the length-diameter ratio of the softening cover is large, and needs to be manually taken out at the moment, or the other method is to increase the length of an ejector rod to eject the softening cover. The above two methods have the following problems: the softening cover is taken out manually, so that the labor intensity of repeated labor is increased, the time for taking the softening cover is in the time gap between the concave die and the convex die, and certain potential safety hazards are caused; the length of the ejector rod is increased, the ejection stroke of the ejector rod can be increased, the size of the forming machine is larger, the equipment cost is increased, the occupied area of the equipment is increased, and the integral manufacturing cost is increased.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a preparation hotbed chives is planted and is softened mould demoulding mechanism for cover. The utility model has the characteristics of simple structure eliminates potential safety hazard and reduction in production cost.
The technical scheme of the utility model: the mold demolding mechanism for the hotbed chives planting softening cover comprises a push plate, wherein a push rod of a hollow structure is fixedly arranged on the push plate, one end of the push rod is a closed end, an air pipe connector is arranged at the other end of the push rod, and an exhaust hole is formed in the side wall, close to one end of the closed end, of the push rod.
In the mold demolding mechanism for preparing the hotbed chives planting softening cover, the exhaust holes are oblique exhaust holes.
In the die demolding mechanism for preparing the hotbed chives planting softening cover, the oblique angle theta of the oblique exhaust hole is 10-30 degrees.
Compared with the prior art, the push plate of the utility model is fixedly provided with the ejector rod with a hollow structure, one end of the ejector rod is a closed end, the other end of the ejector rod is provided with the air pipe joint, and the side wall of the ejector rod close to one end of the closed end is provided with the exhaust hole; through the structure, when in demoulding, the push plate firstly pushes the ejector rod to eject the formed softening cover for a short distance, so that the outer side wall of the softening cover is separated from the inner wall of the cavity of the female die, and the exhaust holes on the side wall are exposed; then introducing pressurized air to the ejector rod, and exhausting the pressurized air along the exhaust hole to blow out the softened cover in the cavity of the female die; although the structure is simple, the scheme of manually taking out the softening cover and pushing out the softening cover by the large-stroke ejector rod is replaced, the potential safety hazard generated by manual operation is eliminated, the ejection stroke of the ejector rod is shortened, the equipment requirement is reduced, the equipment floor area is reduced, and finally the production cost is reduced.
Drawings
FIG. 1 is a diagram illustrating the usage of the present invention;
fig. 2 is a usage state diagram of the present invention.
The labels in the figures are: 1-push plate, 2-ejector rod, 3-air pipe joint, 4-exhaust hole, 5-male die, 6-female die, 7-softening cover and 8-cavity wall of female die.
Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. A mould demoulding mechanism for preparing a hotbed chives planting softening cover is shown in a figure 1-2 and comprises a push plate 1, wherein a push rod 2 of a hollow structure is fixedly arranged on the push plate 1, one end of the push rod 2 is a closed end, the other end of the push rod 2 is provided with an air pipe connector 3, and an exhaust hole 4 is formed in the side wall of one end, close to the closed end, of the push rod 2.
When in use, the demoulding mechanism is arranged on the mould according to the mode shown in figure 2, the mould with the demoulding mechanism arranged is arranged on an EPS forming machine according to the conventional mode, and the air pipe joint 3 of the ejector rod 2 is connected with an air source; after the softening cover is formed, the male die 5 is separated from the female die 6, and after separation, the push plate 1 is pushed (only by adopting a hydraulic mechanism) to drive the ejector rod 2 to eject the softening cover 7 out, so that the softening cover 7 is separated from the cavity wall 8 of the female die, and the exhaust hole 4 is also exposed in the cavity of the female die; and then introducing pressurized air into the ejector rod 2, and exhausting the pressurized air along the exhaust hole 4 to blow out the softening cover 7 in the cavity of the female die.
The exhaust hole 4 is an oblique exhaust hole. This arrangement makes it more convenient for the pressurized air to blow the softening cover 7 out.
The inclined angle theta of the inclined exhaust hole is 10-30 degrees.
