Description

Technical Field

[0001] The present invention relates to the technical field of molds, and specifically to a mold for displaying clothing. Background Art

[0002] Plastic mannequins for clothing are commonly used props in clothing displays, with various advantages, different types, and selection methods. Compared with real human mannequins, plastic mannequins have lower costs and are more suitable for large-scale use; the appearance of plastic mannequins can be customized according to different display requirements, including skin color, hairstyle, clothing style, etc., to meet the personalized needs of different brands and stores; plastic mannequins are usually made of lightweight materials, which are convenient for handling and storage, and can be disassembled and assembled, occupying less space; plastic mannequins can pose in various positions to display the characteristics and advantages of products, attracting the attention of customers; plastic mannequins are usually produced through injection molds.

[0003] An injection mold is a key tool used in the injection molding process, mainly for manufacturing plastic products with complex shapes; the injection mold heats and melts the plastic material, then injects it into the mold cavity, cools it to form, and finally obtains the required plastic product. It usually consists of a fixed mold and a moving mold. After the molds are closed, a mold cavity is formed. Under the pressure of an injection molding machine, the plastic material is injected into the mold cavity. After cooling and solidifying, the mold can be opened to take out the finished product. The injection process can carry out large-scale production. The mold can maintain good repeatability during long-term use, ensuring the consistency of each part. At the same time, the injection molding cycle is short, usually only taking a few seconds to a few minutes to complete one injection; injection molds are generally made of high-strength steel or aluminum alloy materials, with good wear resistance and corrosion resistance, and can withstand high-temperature and high-pressure working environments, having a long service life; in some existing injection molds, during the molding process, since the injection mold itself is cold, the raw material solution is likely to cool down prematurely during the entry process, resulting in a large number of defective products.

[0004] In view of the above problems, the present invention is proposed. Summary of the Invention

[0005] Aiming at the deficiencies existing in the prior art, the purpose of the present invention is to provide a mold for displaying clothing to solve the problems mentioned in the background art.

[0006] To solve the above technical problems, the present invention provides the following technical solutions.

[0007] The present invention provides a mold for displaying clothing, including a bottom plate and a top plate. The top plate is directly above the bottom plate. Four corner positions on the upper surface of the bottom plate are vertically provided with guide rods, and the upper ends of the guide rods are fixed at four corner positions on the lower surface of the top plate;

[0008] A plurality of hydraulic rods are vertically arranged on the upper surface of the top plate. The telescopic rods of the hydraulic rods face downward. A pressing plate is arranged at the telescopic rod end of the hydraulic rod. The pressing plate is horizontal and is directly above the bottom plate. The guide rods are inserted at the four corner positions of the pressing plate.

[0009] A lower mold is arranged on the upper surface of the bottom plate. An upper mold is arranged on the lower surface of the pressing plate. The lower mold is directly below the upper mold. A lower cavity is arranged on the upper surface of the lower mold. A punch is arranged in the center of the lower surface of the upper mold. The punch is directly above the lower cavity.

[0010] On both sides of the front of the lower mold, first heating plates are arranged. On both sides of the lower mold, second heating plates are arranged. At the middle position of the front of the lower mold, a feed inlet pipe communicating with the inside of the lower mold is arranged.

[0011] Preferably, springs are arranged around the guide rods. The upper ends of the springs are fixed on the lower surface of the pressing plate. The lower ends of the springs are fixed on the upper surface of the bottom plate. The central axis of the spring coincides with the vertical axis of the guide rod.

[0012] Preferably, a controller is arranged on the upper surface of the top plate. The controller is connected to the hydraulic rods for control. Between the surface of the hydraulic rod and the upper surface of the top plate, a plurality of reinforcing rib plates are arranged. The plurality of reinforcing rib plates are evenly distributed at equal intervals around the hydraulic rod and the top plate.

[0013] Preferably, the feed inlet pipe communicates with the lower cavity. Feed holes are arranged on the inner bottom surface of the lower cavity. The outlet of the feed inlet pipe communicates with the feed holes.

[0014] Preferably, an air inlet pipe is arranged on the back of the lower mold. Air inlet holes are arranged on the inner bottom surface of the lower cavity. The air inlet pipe is connected to the air inlet holes. The contour of the lower cavity is the same as that of the punch. The depth of the lower cavity is the same as the thickness of the punch.

[0015] Preferably, slots are arranged around the upper surface of the lower mold. Insert bars are arranged around the lower surface of the upper mold. The insert bars are directly above the slots. The contour of the insert bars is the same as that of the slots. The thickness of the insert bars is the same as the depth of the slots. The slots are arranged around the upper surface of the lower cavity.

[0016] Preferably, an exhaust pipe, a first air pump and a valve are arranged on the side of the upper mold. A gas extraction port is arranged on the lower surface of the punch. One end of the exhaust pipe is connected to the first air pump. The other end of the exhaust pipe communicates with the gas extraction port. The valve is arranged on the exhaust pipe.

[0017] Preferably, a side support is provided on the left side surface of the bottom plate. A second air pump is provided on the upper surface of the side support. A flared opening is provided on the upper surface of the left side of the bottom plate. The small opening of the flared opening is connected to the air inlet of the second air pump, and the large opening of the flared opening faces the lower mold and the upper mold.

[0018] Preferably, there are four hydraulic rods, and the four hydraulic rods are evenly distributed on the top plate at equal intervals. Through holes adapted to the guide rods are provided at the four corner positions of the pressing plate, and the guide rods penetrate through the through holes.

[0019] Preferably, the corner positions of the inner bottom surface of the lower cavity are arc-shaped, and the corner positions of the upper surface opening of the lower cavity are arc-shaped.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The pressing plate is located directly above the bottom plate. The telescopic movement of the hydraulic rods can drive the up and down movement of the pressing plate, and the upper mold can move up and down with the movement of the pressing plate. When the upper mold moves downward, the punch can just enter the lower cavity.

[0022] During use, the plastic raw material particles for injection are melted and then injected into the lower cavity through the feed port pipe. At this time, the punch is located in the lower cavity, and there is a gap between the outer surface of the punch and the inner wall of the lower cavity. The molten plastic raw material will fill the gap between the punch and the lower cavity.

[0023] During the process of injecting the raw material, the first heating plate and the second heating plate are always powered on. In this way, the lower mold is always in a relatively high temperature state. In this way, when the molten plastic raw material flows between the lower cavity and the upper mold, it will not cool and solidify too quickly, and the forming quality can be guaranteed.

[0024] During the process of injecting the raw material, the first air pump works. The air between the lower cavity and the punch can flow into the exhaust pipe through the air extraction port and then be discharged. In this way, the air content in the gap between the lower cavity and the punch is small, almost approaching a vacuum state. In this way, no air enters the raw material during the forming process of the molten plastic raw material, and the structural strength of the formed product is better. Moreover, when the punch is located in the lower cavity, the insert just inserts into the slot, so that the lower mold and the upper mold are in an enclosed and sealed state, which is convenient for the air between the punch and the lower cavity to be discharged.

[0025] After the molding is completed, the hydraulic rod moves upward. The hydraulic rod drives the upper mold and the punch away from the lower mold and the lower cavity. At this time, the molded clothing model is located in the lower cavity. Gas is sent into the air inlet pipe, and the gas can be ejected from the air inlet. In this way, the gas can quickly fill the bottom of the lower cavity, and the gas can slightly push the molded clothing model upward, so that the lower surface of the molded clothing model leaves the upper surface of the lower cavity, which is convenient for workers to quickly take down the molded clothing model.

[0026] When the molding is completed and the hydraulic rod moves upward, the second air pump works. The unpleasant plastic smell generated between the lower mold and the upper mold can quickly enter the bell mouth and be discharged uniformly. In this way, it can avoid the unpleasant plastic smell from irritating the respiratory tract of workers and can protect the workers. Brief Description of the Drawings

[0047] The corner positions of the inner bottom surface of the lower cavity 21 are arc-shaped, and the corner positions of the upper surface opening of the lower cavity 21 are arc-shaped.

[0048] In summary: The pressing plate 16 is located directly above the bottom plate 1. The telescopic movement of the hydraulic rod 13 can drive the up and down movement of the pressing plate 16, and the upper mold 18 can move up and down along with the movement of the pressing plate 16. When the upper mold 18 moves downward, the punch 19 can just enter the lower cavity 21;

[0049] During use, the plastic raw material particles for injection are melted and then injected into the lower cavity 21 through the feed port pipe 24. At this time, the punch 19 is located in the lower cavity 21, and there is a gap between the outer surface of the punch 19 and the inner wall of the lower cavity 21. The melted plastic raw material will fill the gap between the punch 19 and the lower cavity 21;

[0050] During the process of injecting the raw material, the first heating plate 22 and the second heating plate 23 are always powered on.

When the molten plastic raw material flows between the lower cavity 21 and the upper mold 18, it will not cool and solidify too quickly, which can ensure the forming quality;

[0051] During the process of injecting the raw material, the first air pump 29 works. The air between the lower cavity 21 and the punch 19 can flow into the exhaust pipe 28 through the air extraction port 191 and then be discharged. In this way, the air content in the gap between the lower cavity 21 and the punch 19 is small, almost approaching a vacuum state. When the molten plastic raw material is forming, no air enters the raw material, so that the formed product has better structural strength; and when the punch 19 is located in the lower cavity 21, the insertion strip 181 just inserts into the slot 20. In this way, the lower mold 2 and the upper mold 18 are in an enclosed and sealed state, which is convenient for the air between the punch 19 and the lower cavity 21 to be discharged;

[0052] When the forming is completed, the hydraulic rod 13 moves upward. The hydraulic rod 13 drives the upper mold 18 and the punch 19 away from the lower mold 2 and the lower cavity 21. At this time, the formed mannequin is located in the lower cavity 21. Gas is sent into the air inlet pipe 25, and the gas can be ejected from the air inlet 27. In this way, the gas can quickly fill the bottom of the lower cavity 21, and the gas can slightly push the formed mannequin upward, so that the lower surface of the formed mannequin leaves the upper surface of the lower cavity 21, which is convenient for workers to quickly take down the formed mannequin;

[0053] When the forming is completed and the hydraulic rod 13 moves upward, the second air pump 31 works. The unpleasant plastic smell generated between the lower mold 2 and the upper mold 18 can quickly enter the bell mouth 32 and be discharged uniformly.
