Description

Technical Field

[0001] This invention relates to the field of mold manufacturing technology, specifically to a manufacturing process for a high-precision, high-strength POM mold. Background Technology

[0002] Rubber gloves (including nitrile, latex, PU, ​​and PVC gloves, hereinafter referred to as rubber gloves) are common items in our daily lives. Due to their advantages such as low price and waterproofness, they are widely used. In the current technology, rubber gloves are made by pouring liquid glue onto a hand mold, waiting for the glue on the hand mold to solidify, and then demolding. The hand mold used to make rubber gloves plays an important role in the entire processing process, and the quality of the hand mold directly affects the quality of the rubber gloves produced.

[0003] Current technologies for hand mold making utilize aluminum, ceramic, and POM (polypropylene) mixed plastic molds. Aluminum molds, however, suffer from poor corrosion resistance and are prone to oxidation after molding, resulting in a short lifespan. While ceramic molds offer good corrosion resistance, they are heavy, inconvenient to use, and fragile, also leading to a short lifespan. Therefore, most existing hand molds use POM mixed plastic. However, the molding process of existing POM mixed plastic hand molds involves injecting raw material into the mold, which results in poor flowability within the mold, leading to poor precision and a low yield rate. Furthermore, the low level of automation in existing molding equipment further contributes to low production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a manufacturing process for high-precision, high-strength POM molds, which enables the raw material injected into the mold to flow fully and evenly, thereby improving the mold forming accuracy and the yield rate of hand molds. At the same time, the molding equipment has a high degree of automation, which greatly improves the efficiency of hand mold making.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A manufacturing process for a high-precision, high-strength POM mold includes the following steps:

[0007] Step 1: POM raw material is poured in through the third feed pipe and then enters the melting tank through the second feed pipe. The second electric heating plate in the melting tank then heats and melts the material, while the stirring mechanism stirs it.

[0008] Step 2: Start the first electric heating plate inside the upper shell mold and the lower shell mold to preheat the mold. Then, the second electric telescopic rod drives the molten material box to move downward. Then, molten raw material is injected into the upper shell mold and the lower shell mold on the mold placement mechanism.

[0009] Step 3: After the raw materials in Step 2 are injected into the mold, the first electric heating plate is turned off. Then the first motor is started to drive the lower shell mold and the upper shell mold to rotate.

Subsequently, the first electric telescopic rod 192 on the upper shell mold 19 moves the baffle 191 to open the first feed pipe 190. Simultaneously, the raw material is fed into the second feed pipe 56 inside the melting tank 53 through the third feed pipe 57. Then, the solenoid valve on the second feed pipe 56 is closed, and the raw material is then fed into the melting tank 53. The second electric heating plate 54 inside the box 53 heats the raw material to melt it, while the stirring mechanism stirs the raw material to ensure it is heated and melted evenly. The melted raw material moves the melting box 53 downward via the second electric telescopic rod 52, causing the discharge pipe 55 at the bottom of the melting box 53 to be inserted into the first feed pipe 190 in the upper shell mold 19.

The second drive shaft 32 rotates via the third drive gear 33 and the fourth drive gear. 34 drives the second support shaft 4 to rotate 180°, and then the second electric telescopic rod drives the molten material box to move upward to inject material into the mold on the other side, thereby realizing automatic feeding of the mold, improving the automation level of mold forming, and also improving the mold manufacturing efficiency. Subsequently, the first transmission mechanism drives the first support shaft 2 to rotate, and the first support shaft 2 drives the support column 3 to rotate up and down on the mounting frame 1. At the same time, the second transmission mechanism drives the second support shaft 4 to rotate, and the second support shaft 4 drives the mounting box 5 to rotate.

The body placement mechanism rotates, and simultaneously the first motor 12 drives the first rotating shaft 13 to rotate. The first rotating shaft 13 drives the second rotating shaft 16 to rotate through the first gear 14 and the second gear 15. The second rotating shaft 16 drives the mounting plate 17, the upper shell mold 19, and the lower shell mold 18 to rotate, thereby realizing multi-angle and multi-directional rotation of the forming mold, improving the fluidity of the raw material in the forming mold, so that the raw material is fully formed in the mold, thereby improving the yield of the forming mold, improving the precision of hand mold production, and allowing the raw material to be cooled and formed evenly, thereby improving the overall strength of the hand mold.

[0047] The smoke extraction machine 73 and the pipes adsorb the smoke extraction tube 72. Then, the smoke extraction tube 72 draws in the gas in the support frame 51 through the smoke extraction hood 71. The smoke extraction machine 73 then passes the drawn-in smoke into the existing flue gas treatment equipment for treatment, thereby reducing the need for timely treatment of flue gas during production and reducing the pollution of flue gas to the environment.
