Description

Technical Field

[0001] This utility model relates to the field of melamine tableware technology, and in particular to a molding die that is easy to demold. Background Technology

[0002] Melamine plastic tableware, also known as imitation porcelain tableware, is widely used in the fast food industry and children's food industry. In the current production and processing of melamine tableware, a certain amount of melamine resin powder needs to be added into the mold body, and then it is cured and molded by high temperature and high pressure through hot pressing equipment. After curing, the melamine plastic needs to be lifted out of the mold body to achieve the demolding of melamine plastic tableware.

[0003] Chinese Patent CN221860923U discloses a melamine tableware molding and demolding device, including a mold body and a mold base. The mold body has a mold base on top, and a top ring is provided inside the mold base. Adjustment seats are provided at both ends of the bottom of the top ring. A push rod is provided between the top of the adjustment seat and the top ring. The surface of the adjustment seat has a groove. One end of the push rod inside the adjustment seat has a handle. In this invention, during the hot pressing process, the melamine resin powder in the mold body overflows from the mold body and forms on the mold base. At this time, the operator can hold the handle and push the push rod upward. The rising push rod pushes the top ring out of the ring groove in the mold base. The ejected top ring contacts the overflowing part on the mold base, which can simultaneously lift the melamine tableware in the mold body, thereby realizing the demolding work. During the demolding process, the overall force is uniform, the ejection is stable, and the melamine tableware body will not deform due to the squeezing force.

[0004] When using existing melamine tableware molding and demolding devices, the operator holds the handle and pushes the ejector rod upwards. The mold base and ejector ring work together to lift the molded melamine tableware out. However, manually pushing the handle upwards for a long time and repeatedly can easily cause operator fatigue. This leads to uneven demolding force after prolonged operation, affecting the final lifting effect of the molded melamine tableware, reducing the ease of demolding the melamine tableware mold body, and reducing the effectiveness of the demolding structure of the mold body.

[0029] Example 1

[0030] like Figure 1 - Figure 4As shown, the present invention proposes a molding die for easy demolding, comprising: a base plate 1, a lifting assembly 2, a die body 3, a die base 4, and a top ring 5; the base plate 1 is connected to a housing 101, and the housing 101 is connected to a guide member; two lifting assemblies 2 are provided, and the two lifting assemblies 2 are respectively connected to the base plate 1; the lifting assembly 2 includes a connecting block a201, a cylinder 202, a mounting rod 203, a connector, and a lifting rod 206; the connecting block a201 is connected to the base plate 1, the connecting block a201 is connected to the cylinder 202, the driving end of the cylinder 202 is connected to the mounting rod 203, and the mounting rod 203 is connected to the lifting rod 206 through the connector; the die body 3 is connected to the housing 101, the die body 3 is provided with a die base 4, the die body 3 is connected to the top ring 5, and the two sides below the top ring 5 are connected to the lifting rod 206. By using cylinder 202 for demolding, uneven force during demolding is avoided, which facilitates the lifting effect of the melamine tableware produced as a whole and improves the demolding structure of the molding mold body.

[0031] To further explain, the mold body 3 has four openings on its periphery, through which two lifting rods 206 and two connecting rods 501 slide respectively; the connecting rods 501 are connected to the other two sides below the top ring 5. The four openings facilitate the connection and cooperation of the overall structure of the molding mold for easy demolding, improving its practicality.

[0032] Further explanation: The guide component includes a support column 102, four vertical plates 103, a guide block 104, a support rod 105, and a mounting block 106. The support column 102 is connected inside the housing 101. Grooves are provided on both sides of the support column 102. The inner walls of the grooves are connected to the four vertical plates 103. The four vertical plates 103 are arranged in pairs, and the spacing between the pairs of vertical plates 103 forms a moving channel. The guide block 104 and the support rod 105 correspond one-to-one. The guide block 104 is connected to the moving channel and is connected to the support rod 105. The support rod 105 is connected to the mounting block 106. The support rod 105 passes through an opening to connect the mounting block 106 and the connecting rod 501. The opening is located on both sides of the housing 101. The mounting block 106 is threaded with a screw, which passes through the connection hole of the mounting block 106 and the connecting rod 501 for threaded connection. This facilitates the connection between the guide and the connecting rod 501, making it easier to lift the top ring 5 out or reset it downwards smoothly, improving the uniformity of lifting out, and facilitating the demolding of melamine tableware. It is detachably connected to the cylinder 202, the base plate 1, and the connecting block c205, making it easy to replace or repair the cylinder 202 according to its service life, and improving the structural performance of the lifting component 2.

[0033] Example 2

[0034] like Figure 2As shown, this utility model proposes a molding die that is easy to demold. Based on the above embodiments, this embodiment also details the specific components of the connector and the connecting block a201, as well as their mating methods.

[0035] Further explanation: the connector includes connecting block b204 and connecting block c205; connecting block b204 is connected to the mounting rod 203, connecting block c205 is connected to connecting block b204 and is detachably connected, connecting block c205 is connected to the lifting rod 206; connecting block b204 and connecting block c205 have the same structure and are each provided with two reserved mounting holes b; connecting block a201 is provided with four reserved mounting holes a, and connecting block a201 and base plate 1 are detachably connected. Connecting block a201 is connected by screws through the reserved mounting hole a and the reserved connecting hole a. The reserved connecting hole a is set on the base plate 1 to facilitate the connection between connecting block a201 and the base plate 1. Bolts are used to pass through the reserved mounting holes a of connecting block b204 and connecting block c205. The bolt threads are matched with nuts to install connecting block b204 and connecting block c205. This facilitates the connection between lifting rod 206 and mounting rod 203, and facilitates the use of cylinder 202 to lift out the top ring 5, making it easy for melamine tableware to be demolded from the mold body 3 for use.

[0036] The working principle of this utility model is as follows: When using the molding mold that facilitates demolding, the operator first adds a certain amount of melamine resin powder into the mold body 3, then starts the top hot press equipment. The hot press head at the bottom of the equipment, corresponding to the shape of the mold, performs hot pressing and curing. After the hot pressing is completed, the mold body 3 is raised and reset, and the melamine resin powder inside is cured into melamine tableware of the corresponding shape and specifications, thus completing the melamine tableware molding process. During the hot pressing process, the melamine resin powder inside the mold body 3 overflows from the mold body 3 and forms on the mold base 4. At this time, the operator starts the cylinder 202, and the cylinder 202 drives the mounting rod 203 upward. The mounting rod 203 drives the connecting block b204 and the connecting block... c205 causes the lifting rod 206 to move upward. The lifting rod 206 is connected to the top ring 5. The top ring 5 contacts the melamine tableware overflowing from the mold base 4, thereby simultaneously lifting the melamine tableware out of the mold body 3 and completing the demolding process. During the demolding process, the top ring 5 is connected to the mounting block 106 through the connecting rod 501, causing the mounting block 106 to move downward at the same time. The mounting block 106 drives the support rod 105, and the support rod 105 causes the guide block 104 to move in the moving channel, which facilitates the uniformity of the top ring 5 popping out and makes it easier for the melamine tableware to be demolded from the mold body 3. After the melamine tableware is demolded, the overall structure of the demolding mold is reset, which is convenient for secondary melamine tableware production and processing, and improves the use of the demolding mold.

[0037] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
