TECHNICAL FIELD

[0001] The present application relates to the field of molds, in particular to a mold rapid heating structure. BACKGROUND

[0002] The basic process of the pre-preg compression molding (PCM) forming process is: the pretreated molding material is put into the preheated mold to apply high pressure to fill the mold cavity, and the molding material is gradually solidified under certain pressure and temperature, then the product is taken out of the mold, and necessary auxiliary processing is carried out to obtain the product. For the special-shaped mold that needs to be heated uniformly, the heating sheet heating in the related art cannot achieve the effect of uniform temperature distribution, and uneven heating in production can easily lead to poor product appearance and gas leakage. SUMMARY

[0003] Therefore, the present application provides a mold rapid heating structure to solve the problem of uneven heating of the mold.

[0004] In order to achieve the above purpose, the present application realizes the following technical scheme:

[0006] The above-mentioned mold rapid heating structure of the present application sets an oil channel in the mold, so that the hot oil can circulate in the mold, thereby realizing rapid heating of the mold. For the special-shaped part, the heating oil can reach the area by designing the oil channel, realizing uniform heating, improving the product appearance and reducing gas leakage.

[0007] In some embodiments, the oil inlets of at least two oil channel units are arranged on the left and right sides of the mold plate. The mold usually has a faster heat dissipation speed on the outer periphery and a slower heat dissipation speed in the middle position, and the oil temperature of the oil inlet is higher than that of the oil outlet. By arranging at least two oil inlets on the left and right sides of the mold plate, the uniformity of the heating temperature is ensured.

[0008] In some embodiments, the template is internally provided with a plurality of first oil holes arranged at intervals left and right, the first oil holes are arranged in the front-rear direction, the front and rear ends of the first oil holes are respectively provided with a second oil hole and a third oil hole which are vertically arranged and communicated with the first oil hole, and two fourth oil holes are arranged at intervals front and rear and extend in the left-right direction on the template, one of the fourth oil holes is communicated with each second oil hole, and the other fourth oil hole is communicated with each third oil hole, and the fourth oil hole is arranged in the up-down direction with the first oil hole.

[0009] The opening end of the first oil hole is fixedly provided with a first plug, so that the inner cavity of the first oil hole constitutes the first oil cavity, the opening end of the second oil hole and the third oil hole is fixedly provided with a second plug, and a plurality of third plugs are arranged at intervals in the two fourth oil holes, the cavity between the adjacent two third plugs of the fourth oil hole constitutes the second oil cavity, and a fourth plug is further arranged at the opening end of the fourth oil hole.

[0010] The purpose of such arrangement is to facilitate the formation of the oil path in the interior of the template, wherein the hole positions can be formed by drilling during processing, and the required oil path is formed by arranging the plugs at the corresponding positions.

[0012] The third plug is fixed to the rod, which is to facilitate the installation and later maintenance of the third plug. When the oil path is blocked, the fourth plug is removed, and the entire rod and the third plug thereon are taken out together for dredging. During installation, as long as the rod is installed in place, the third plug can be placed in place automatically.

[0013] In some embodiments, the rod is a screw rod, the third plug is movably sleeved on the screw rod, and the limiting structure is a nut threadedly connected to the screw rod, and two or more nuts fix the third plug from both sides of the third plug. The third plug is more convenient to adjust in position by being arranged as a threaded connection structure. The limiting structure can also be an internal thread formed directly on the third plug or other structures.

[0014] In some embodiments, the fourth plug and the fourth oil hole are threadedly connected.

The terms used in the embodiment part of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application.

[0025] Reference Figures 1 to 5 The embodiment of the present application provides a mold rapid heating structure, which comprises a mold plate 1, two or more oil passage units for circulating hot oil are arranged on the mold plate 1, the oil passage unit comprises an oil passage 3 arranged in the mold plate 1, the oil passage 3 comprises a plurality of first oil cavities 31 arranged left and right, and a plurality of second oil cavities 32 for connecting adjacent two first oil cavities 31, each second oil cavity 32 is arranged in a front and rear manner, and an oil inlet 4 and an oil outlet 5 are further arranged at the head and tail of the oil passage 3 respectively. The oil inlet 4 and the oil outlet 5 are connected with a hot oil supply device.

[0026] Due to the oil passage 3 arranged inside the mold, the hot oil can flow in the mold, so that the mold can be heated quickly. The heating oil can reach the area of the different parts by designing the oil passage 3, so that the heating is uniform, the appearance of the product is improved, and the gas leakage is reduced.

[0027] The number of specific oil passage units can be increased or decreased according to the actual molded product, which can be two, three or other. In some embodiments, the oil inlet 4 of at least two oil passage units is arranged on the left and right sides of the mold plate 1. The oil outlets 5 of the corresponding two oil passage units are distributed in the middle position.

[0028] The mold is generally fast in the peripheral heat dissipation speed, and slow in the middle position heat dissipation. The oil temperature of the oil inlet 4 is higher than that of the oil outlet 5. At least two oil inlets 4 are arranged on the left and right sides of the mold plate 1, so as to ensure the uniformity of the heating temperature.

[0029] In some embodiments, a plurality of first oil holes 6 are arranged on the left and right sides of the mold plate 1. The first oil holes 6 are arranged in the front-rear direction. The front and rear ends of the first oil holes 6 are respectively provided with a second oil hole 7 and a third oil hole 8 which are vertically arranged and communicated with the first oil hole 6. Two fourth oil holes 9 are arranged in the front-rear direction and extend in the left-right direction. One of the fourth oil holes 9 communicates with each second oil hole 7, and the other fourth oil hole 9 communicates with each third oil hole 8. The fourth oil hole 9 is arranged in the up-down direction with the first oil hole 6.

[0030] The opening end of the first oil hole 6 is fixedly provided with a first plug 10, so that the inner cavity of the first oil hole 6 constitutes a first oil cavity 31. The opening end of the second oil hole 7 and the third oil hole 8 is fixedly provided with a second plug 101. A plurality of third plugs 102 are arranged in the fourth oil hole 9. The cavity between the adjacent two third plugs 102 of the fourth oil hole 9 constitutes a second oil cavity 32. A fourth plug 103 is arranged at the opening end of the fourth oil hole 9.

[0031] The purpose of such arrangement is to facilitate the formation of the oil passage 3 inside the mold plate 1. The hole position can be formed by drilling during processing, and the plug is arranged at the corresponding position to form the required oil passage 3.

[0032] In some embodiments, a rod is arranged in the fourth oil hole 9. The third plug 102 is connected to the rod in a position-adjustable manner. A limiting structure for fixing the third plug 102 to the rod is arranged on the rod. The fourth plug 103 is detachably connected to the opening of the fourth oil hole 9.

[0033] The third plug 102 is fixed on the rod, so as to facilitate the installation and later maintenance of the third plug 102. When the oil passage 3 is blocked, the fourth plug 103 is removed, and the rod and the third plug 102 thereon are taken out together, and then dredged.
