Description

Technical Field

[0001] The invention relates to the technical field of mold application, and in particular to an optimized and improved structure of a mold. Background Art

[0002] A mold is a tool used to make molded objects. This tool is composed of various parts. Different molds are composed of different parts. In industrial production, various molds and tools are used to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping, etc. It mainly realizes the processing of the shape of the object by changing the physical state of the molded material.

[0003] As attached Figure 2 As shown in the figure, the original mold structure has a long heat transfer distance, a small effective heat transfer area (especially the lower mold), serious heat waste, a long temperature control response time, a large temperature fluctuation range (generally around 20-30°C), and a high defective rate.

[0004] Due to the large temperature difference between the heating plate and the mold cavity, when the mold cavity temperature reaches the set value, the heat of the heating plate will continue to be transferred to the mold cavity, causing the actual temperature of the mold cavity to be about 10-15°C higher than the set value.

[0005] When the mold cavity temperature is lower than the set value, the electric heating tube heats up. However, it takes some time for the mold cavity to get supplementary heat from heating, and during this period of time, the mold cavity temperature continues to drop by 8-12 ℃.

[0006] When the temperature is too high (above 163°C), the coil skeleton softens and deforms, and the product is scrapped; when the temperature is too low (below 145°C), the epoxy resin has poor fluidity, the injection is insufficient, and the product is scrapped; increasing the injection pressure will break the enameled wire, and the product will still be scrapped.

[0007] Therefore, no matter how the set temperature value (around 150°C) is adjusted, it is difficult to find an ideal temperature point that takes both ends into consideration, and the overall qualified rate of the product is always below 94%.

[0008] In summary, a new type of mold structure is needed to change the way heat acts on the mold and improve the defects of the original mold, such as low heat transfer efficiency and excessive temperature drift. Therefore, an optimized and improved structure of the mold is proposed. Summary of the invention

[0009] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide an optimized and improved structure of the mold, which has the advantages of high heat transfer efficiency, greatly reduced temperature drift, and reduced defective rate.

[0010] The above technical objectives of the present invention are achieved through the following technical solutions:

[0011] An optimized and improved structure of a mold comprises an upper mold plate, a feed tube is provided on the top of the upper mold plate, a first heating tube insertion hole is provided at the feed tube and is arranged to penetrate the feed tube transversely, and a plurality of groups of the first heating tube insertion holes are distributed in parallel along a uniform horizontal line;

[0012] A lower template is installed at the bottom of the upper template, a heating plate is fixedly installed at the bottom of the lower template, a heating cavity is provided on the top of the heating plate, and the bottom of the lower template is embedded in the heating cavity, and a second heating pipe jack is provided at the heating plate and is arranged to penetrate the heating plate transversely;

[0013] Electric heating tubes are inserted into the first heating tube socket and the second heating tube socket. The electric heating tubes are directly installed at the feed barrel and are convenient for directly applying heat to the upper template. The heating plate forms a covering structure for the lower template. When the electric heating tube is inserted into the second heating tube socket, the heat directly acts on the lower template, so that the temperature inside the lower template is well maintained. The temperature drift at the upper template and the lower template is controlled within 6°C.

[0014] Furthermore, a feed port is provided on the top surface of the feed barrel, a feed rod is provided directly above the feed port, the top of the feed rod is fixedly connected to a feed rod base, the top of the feed rod base is fixedly connected to an upper fixed plate, and an upper heat insulation plate is fixedly installed between the upper fixed plate and the feed rod base.

[0015] Furthermore, a pad is fixedly connected to the bottom of the heating plate, the pad is fixed on the left and right sides of the bottom of the heating plate, and an active cavity is formed between the pad and the bottom of the heating plate.

[0016] Furthermore, a lower heat insulation board is fixedly connected to the bottom of the cushion block, and a lower fixing board is fixedly installed to the bottom of the lower heat insulation board.

[0017] Furthermore, a return spring is fixedly installed inside the movable cavity, and the return springs are installed in pairs at both ends of the movable cavity.

[0018] Furthermore, a positioning rod is provided between the feed rod base and the feed barrel, the positioning rod is fixedly mounted on the bottom of the feed rod base, and the bottom of the positioning rod is mounted inside the upper template and the feed barrel 2.

[0019] Furthermore, the upper template and the heating plate are provided with a temperature detection device, and the temperature detection device may be a thermocouple.

[0020] In summary, the present invention has the following beneficial effects:

[0021] ①The mold structure is simple, and the working principle is the same as that of the traditional mold. The original mold structure is integrated and optimized;

[0022] ②The temperature drift of the mold can be controlled within a relatively low value range, and the entire mold can work continuously and stably within an appropriate temperature range, which is convenient for measuring the temperature and controlling the temperature range of the mold;

[0023] ③The heat at the upper and lower templates can be directly transferred through the electric heating pipes. The transfer path is short, the transfer efficiency is high, the heat loss is small, and the effective area of ​​heat transfer is greatly increased, ensuring high efficiency of heat transfer;

[0024] ④ The defective rate of mold-produced products is low, and the qualified rate of products has been greatly improved. Under the premise of stable quality, the output has been greatly improved, which can be increased by more than 40%;

[0025] ⑤ Due to the improved heat transfer performance and reduced loss, the power consumption of the mold is greatly reduced when it works continuously and stably, saving economic costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

[0032] Embodiment 1: An optimized and improved structure of a mold, such as Figure 1As shown, it includes an upper template 1, a feed barrel 2 is provided on the top of the upper template 1, a first heating tube hole 3 is provided at the feed barrel 2 and is arranged transversely through the feed barrel 2, a plurality of groups of first heating tube holes 3 are distributed in parallel along a uniform horizontal line, an electric heating tube 8 is inserted into the first heating tube hole 3, the electric heating tube 8 directly applies heat to the upper template 1, and the electric heating tube 8 directly heats the inner mold cavity of the upper template 1.

The feed rod 10 is shaped similar to the feed port. A feed rod base 11 is fixedly connected to the top of the feed rod 10, an upper fixed plate 12 is fixedly connected to the top of the feed rod base 11, and an upper heat insulation plate 13 is fixedly installed between the upper fixed plate 12 and the feed rod base 11.

[0035] like Figure 1 As shown, electric heating tubes 8 are inserted into the first heating tube socket 3 and the second heating tube socket 7, and the heating plate 5 forms a covering structure for the lower template 4.

The bottom of the positioning rod 19 is mounted inside the upper template 1 and the feed barrel 2. The positioning rod 19 can assist the upper template 1 to move downward to ensure that the upper template 1 and the lower template 4 can be accurately matched.

[0040] like Figure 1 As shown, a temperature detection device 20 is provided at the upper template 1 and the heating plate 5. The temperature detection device 20 may be a thermocouple.
