[0044] In order to further understand the features, technical means and achieved specific purposes and functions of the present application, the present application is described in further detail below in combination with the drawings and specific embodiments.

[0045] As Figures 1-15 shown, the present application provides:

[0046] The mould pressing process for grass earth production comprises the following steps: S1, closing the mould; S2, inserting the support rod into the mould; S3, after the support rod is completely inserted into the mould, injecting the molten plastic material into the mould to form a grass earth with the support rod but without the bottom; S4, cooling the injected molten plastic material; S5, replacing part of the mould and injecting the molten plastic material again to seal the bottom of the grass earth, thereby completing the production; wherein the closed mould in S1 is the mould 3; the support rod guiding assembly 4a in S2 is the forming mechanism 4, which comprises the support rod guiding blocks 4a6 and the guiding grooves 4a7; the support rod guiding blocks 4a6 are provided in plurality, and the guiding grooves 4a7 are provided on the two side walls of the support rod guiding blocks 4a6; the support rod guiding blocks 4a6 form a ring structure when they are in contact with each other, and the guiding grooves 4a7 form a cylindrical structure when they are in contact with each other; and the sealing mechanism 5 in S5 is used for sealing the bottom of the grass earth.

[0047] Based on the above embodiment, the technical problem to be solved by the present application is how to produce a grass earth with a support rod. To this end, after the mould is closed, the support rod is inserted from outside the mould. After the support rod enters the mould, the support rod is clamped with the guiding grooves 4a7. The support rod guiding blocks 4a6 provide support for the support rod. Then, the molten plastic material is injected into the mould. Since the support rod and the guiding grooves 4a7 are in close cooperation, the molten plastic material cannot enter the gap between the support rod and the guiding grooves 4a7. The two ends of the support rod extend out of the guiding grooves 4a7. Thus, when the molten plastic material is injected, the molten plastic material is located on the two ends of the support rod. Then, the molten plastic material is cooled. At this time, the molten plastic material gradually solidifies, so that the plastic material has a certain supporting performance. Then, the support rod guiding assembly 4a gradually moves away from the mould, and the sealing mechanism 5 replaces the support rod guiding assembly 4a to cooperate with the mould. After confirming that the sealing mechanism 5 and the mould are cooperated, the molten plastic material is injected again. The molten plastic material falls on the upper part of the sealing mechanism 5. After a period of time, the molten plastic material is uniformly distributed on the sealing mechanism 5. Then, the molten plastic material on the sealing mechanism 5 is cooled. Thus, the sealing process of the grass earth is completed. Therefore, the technical requirement of producing a grass earth with a support rod is achieved.

[0050] Based on the above embodiment, the technical problem to be solved by the present application is how the support rod guiding assembly 4a leaves the inside of the mold 3 after completing the guiding of the support rod, so that the bottom sealing mechanism 5 can replace the support guiding assembly to enter the mold 3 to realize the bottom sealing work. To this end, the rotary driver 4a2 is preferably a servo motor, the bracket 1 is provided with two, the bracket 1 is symmetrically arranged about the forming mechanism 4, the conveying mechanism 2 is arranged at the upper part of the bracket 1, the mold 3 is fixedly arranged at the upper part of the conveying mechanism 2, the mold 3 is provided with a forming cavity on the side facing each other, the bottom of the mold 3 is provided with an opening, and the forming cavity is communicated with the opening. When production is needed, the mold 3 provided on the upper part of the conveying mechanism 2 will move towards each other at this time, when the two molds 3 contact each other, the support rod guiding assembly 4a will slowly enter the forming cavity from the opening at the bottom of the mold 3 at this time, so that the first sealing plate 4a9 will seal the opening. At this time, the second connecting rod 4a4 is located on the side of the sliding groove 4a5 close to the center of the rotating block 4a8, the guide blocks 4a6 contact each other, the guide groove 4a7 on the guide block 4a6 is in a cylindrical structure, at this time the support rod is inserted into the guide groove 4a7, then the injection mechanism 7 will start, the injection mechanism 7 will inject molten plastic into the forming cavity, then the cooling mechanism 6 arranged on the mold 3 will cool the molten plastic, after cooling the molten plastic for a period of time, the cooling mechanism 6 will stop running, at this time the rotary driver 4a2 arranged on the bottom plate 4a1 will start to operate, the rotary driver 4a2 will drive the rotating block 4a8 arranged on the output end to rotate, at this time the hinged column arranged on the rotating block 4a8 will push the first connecting rod 4a3 to move, because the two ends of the first connecting rod 4a3 are respectively hinged with the second connecting rod 4a4 and the hinged column, so after the first connecting rod 4a3 is pushed by the hinged column, the first connecting rod 4a3 will push the second connecting rod 4a4 to move, so that the second connecting rod 4a4 will slide along the length direction of the sliding groove 4a5 to the side away from the center of the rotating block 4a8, because the guide block 4a6 is fixedly arranged on the upper part of the second connecting rod 4a4, so when the second connecting rod 4a4 slides along the sliding groove 4a5, the guide block 4a6 will also move at this time, so that the guide blocks 4a6 which are in contact with each other will gradually separate, and at this time the support rod will not be limited by the guide block 4a6, so that when the bottom plate 4a1 is lowered, the guide block 4a6 will not be limited by the support rod, so that the technical requirement that the support rod guiding assembly 4a can leave the inside of the mold 3 after completing the installation of the support rod, so that the bottom sealing mechanism 5 can replace the support guiding assembly to enter the mold 3 to realize the bottom sealing work is realized.

[0051] Further, as shown in Figure 3

[0052] ​The forming mechanism 4 further comprises a base 4b, a first linear actuator 4c and a first guide assembly 4d; the base 4b is fixedly arranged on the ground below the mold 3; the first linear actuator 4c is fixedly arranged at the lower part of the base 4b, the output end of the first linear actuator 4c is vertically upward, and the output end of the first linear actuator 4c is fixedly connected with the bottom of the support rod guiding assembly 4a; the first guide assembly 4d is arranged on the base 4b at the side of the first linear actuator 4c.

[0053] Based on the above embodiment, the technical problem to be solved by the present application is how the support rod guiding assembly 4a is taken out of the mold 3. To this end, the support rod guiding assembly 4a of the present application needs to be taken out of the inside of the mold 3 after completing the guidance for the support rod and assisting the mold 3 to complete the preliminary forming of the grass ball. The first linear actuator 4c is preferably a hydraulic cylinder, at this time the first linear actuator 4c will drive the support rod guiding assembly 4a arranged on its output end to slowly descend, when the output end of the first linear actuator 4c is completely retracted, at this time the support rod guiding assembly 4a will leave the mold 3, and then the bottom sealing mechanism 5 arranged at the bottom of the mold 3 will start to operate, which will seal the opening at the bottom of the mold 3. The first guide assembly 4d arranged at the side of the first linear actuator 4c can prevent the first linear actuator 4c from rotating due to uneven force when it is stretched and retracted. In this way, the technical requirement that the support rod guiding assembly 4a can be taken out of the mold 3 by the first linear actuator 4c is realized.

[0054] Further, as shown in Figures 4-5

[0055] The first guide assembly 4d comprises a first guide hole 4d1 and a first guide rod 4d2; the first guide hole 4d1 is arranged on the upper part of the base 4b and penetrates along the height direction of the base 4b; one end of the first guide rod 4d2 is fixedly arranged at the bottom of the support rod guiding assembly 4a, and the first guide rod 4d2 is slidably arranged on the first guide hole 4d1 along the axis of the first guide hole 4d1.

[0056] Based on the above embodiment, the technical problem to be solved by the present application is how the first guide assembly 4d assists the first linear actuator 4c. To this end, the shape of the first guide hole 4d1 is arbitrary, when the first linear actuator 4c drives the support rod guiding assembly 4a to stretch and retract, at this time the first guide rod 4d2 arranged at the bottom of the support rod guiding assembly 4a will be driven, the first guide rod 4d2 will slide relative to the first guide hole 4d1, in order for the first linear actuator 4c to more stably drive the support rod guiding assembly 4a to realize the stretching and retracting function, the first guide hole 4d1 can be provided with multiple ones, the first guide rod 4d2 corresponds to the first guide hole 4d1 one by one, in this way the assistance of the first guide assembly 4d to the first linear actuator 4c is realized.​

[0057] Further, as shown in Figure 3 and Figure 8 :

[0058] The forming mechanism 4 further comprises an exhaust assembly 4e provided at the top of the mold 3, the exhaust assembly 4e comprising an exhaust hole 4e1 and a first on-off valve 4e2; the exhaust hole 4e1 is provided at least one, the exhaust hole 4e1 is provided at the top of the mold 3 along the height direction of the mold 3; the first on-off valve 4e2 is provided at the upper part of the exhaust hole 4e1.

[0059] Based on the above embodiment, the technical problem to be solved by the present application is how to exhaust the air in the mold 3 in time after the injection mechanism 7 injects the molten plastic into the inside of the mold 3. To this end, the first on-off valve 4e2 will be opened before the injection mechanism 7 injects the molten plastic into the inside of the mold 3, so that the air in the mold 3 will be exhausted from the exhaust hole 4e1 after the molten plastic is injected into the inside of the mold 3. With the injection mechanism 7 continuously injecting the molten plastic into the inside of the mold 3, the molten plastic will gradually approach and eventually contact the exhaust hole 4e1, at which time the first on-off valve 4e2 will be closed, and then the injection mechanism 7 will stop running, and the cooling mechanism 6 will start running, at which time the molten plastic will gradually cool down under the action of the cooling mechanism 6. In this way, the technical requirement that the air in the mold 3 can be exhausted in time after the injection mechanism 7 injects the molten plastic into the inside of the mold 3 is realized.

[0060] Further, as shown in Figure 9 :

[0061] The bottom sealing mechanism 5 comprises a second sealing plate 5a, a second linear actuator 5b, a placing rack 5c and a lifting assembly 5d; the second linear actuator 5b is fixedly provided at the bottom of the mold 3, and the output end of the second linear actuator 5b points to the forming mechanism 4; the placing rack 5c is fixedly provided on the output end of the second linear actuator 5b; the lifting assembly 5d is fixedly provided at the top of the placing rack 5c; the second sealing plate 5a is a semicircular structure, and the second sealing plate 5a is provided at the top of the lifting assembly 5d.

[0062] Based on the above embodiments, the technical problem that this application aims to solve is how the bottom sealing mechanism 5 realizes the bottom sealing function. To this end, the second linear actuator 5b of this application is preferably a hydraulic cylinder. When the molding mechanism 4 leaves the mold 3, the second linear actuator 5b will start to work and drive the placement rack 5c provided on its output end to slowly extend. At this time, the lifting assembly 5d provided on the placement rack 5c will move with the placement rack 5c, carrying the second sealing plate 5a. When the second linear actuator 5b is fully extended, the second sealing plate 5a is located just below the mold 3. Then the lifting assembly 5d will lift the second sealing plate 5a provided on its upper portion, so that the second sealing plate 5a seals the bottom of the mold 3. Thus, the bottom sealing function of the bottom sealing mechanism 5 is realized.

[0063] Further, such as Figure 11 and Figure 13 As shown:

[0064] The lifting assembly 5d includes a third linear drive 5d1, a second guide hole 5d2 and a second guide rod 5d3; the third linear drive 5d1 is fixedly arranged on the placement rack 5c, the output end of the third linear drive 5d1 is vertically upward, and the second sealing plate 5a is fixedly arranged on the output end of the third linear drive 5d1; the second guide hole 5d2 is arranged on one side of the third linear drive 5d1, and the second guide hole 5d2 is opened on the placement rack 5c along the height direction of the placement rack 5c; the second guide rod 5d3 is slidably arranged on the second guide hole 5d2 along the axis of the second guide hole 5d2, and one end of the second guide rod 5d3 is fixedly connected to the bottom of the second sealing plate 5a.

[0065] Based on the above embodiment, the technical problem that this application aims to solve is how the lifting assembly 5d can stably lift the second sealing plate 5a. To this end, the third linear actuator 5d1 of this application is preferably a hydraulic cylinder. When the second linear actuator 5b drives the placement rack 5c to the lower part of the mold 3, the third linear actuator 5d1 will start to operate, and the output end of the third linear actuator 5d1 will slowly extend. The third linear actuator 5d1 will drive the second sealing plate 5a provided on its output end to slowly rise. At this time, the second guide rod 5d3 will slide relative to the second guide hole 5d2. In this way, with the assistance of the second guide rod 5d3, the third linear actuator 5d1 can stably drive the second sealing plate 5a to lift.

[0066] Further, such as Figure 11 and Figure 13 As shown:

[0067] The bottom sealing mechanism 5 also includes a stabilizing component 5e, which is respectively arranged at the bottom of the mold 3 and the placement rack 5c, and the stabilizing component 5e includes a stabilizing block 5e1 and a stabilizing groove 5e2; at least one stabilizing groove 5e2 is provided, and the stabilizing groove 5e2 is opened on the side wall of the placement rack 5c along the length direction of the output shaft of the second linear drive 5b; the stabilizing block 5e1 is fixedly set at the bottom of the mold 3, and the stabilizing block 5e1 is snap-fitted with the stabilizing groove 5e2, and the stabilizing block 5e1 and the stabilizing groove 5e2 correspond to each other.

[0068] Based on the above embodiment, the technical problem that this application seeks to solve is how the stabilizing assembly 5e assists the second linear actuator 5b in driving the placement rack 5c to slide stably. To this end, when the second linear actuator 5b begins to operate, the second linear actuator 5b drives the placement rack 5c, located at its output end, to slowly extend. At this point, the stabilizing grooves 5e2 provided on the side walls of the placement rack 5c slide relative to the stabilizing block 5e1 fixed to the bottom of the mold 3, causing the placement rack 5c to slowly move along the length of the stabilizing block 5e1 via the stabilizing grooves 5e2. This ensures that the second linear actuator 5b can stably drive the placement rack 5c to extend.

[0069] Further, such as Figures 14-15 As shown:

[0071] Based on the above embodiment, the technical problem that this application aims to solve is how the cooling mechanism 6 realizes the cooling function. To this end, when the injection mechanism 7 injects the molten plastic into the interior of the mold 3, the cooling mechanism 6 will start to operate. At this time, the second switch valve 6a set on the water inlet 6b and the water outlet 6c will open simultaneously, so that water will enter from the water inlet 6b, then pass through the cooling pipeline and be discharged from the water outlet 6c, thus realizing the cooling function of the cooling mechanism 6.
