DETAILED DESCRIPTION

[0026] like Figure 1-Figure 4As shown, a multi-layer linkage UDPE bulletproof insert plate hot and cold integrated open molding die comprises an upper template 1 and a lower template 2, a No. 1 template 3 and a No. 2 template 4 are arranged between the upper template 1 and the lower template 2 from top to bottom, a molding cavity 5 is arranged between the upper template 1 and the No. 1 template 3, the No. 1 template 3 and the No. 2 template 4, and the No. 2 template 4 and the lower template 2, and a multi-layer linkage structure is also arranged between the upper template 1, the No. 1 template 3 and the No. 2 template 4.

[0027] In the utility model, the three molding cavities formed by the combination of the upper template 1, the No. 1 template 3, the No. 2 template 4 and the lower template can produce three bulletproof shovel plates at a time, which can effectively improve the production efficiency of the bulletproof plug plates. The multi-layer linkage structure can drive the No. 1 template to move upward when the upper template moves upward to a certain distance, and drive the No. 2 door plate to move upward when the No. 1 template moves to a certain distance, so that the three molding cavities can be opened, and it is only necessary to set a lifting mechanism at the upper template.

[0028] Specifically, the multi-layer linkage structure includes an upper linkage structure 6 arranged between the upper template 1 and the No. 1 template 3 and a lower linkage structure 7 arranged between the No. 1 template 3 and the No. 2 template 4. The upper linkage structure 6 includes an upper linkage plate 9 with a No. 1 vertical slide groove 8. The top of the upper linkage plate 9 is fixed on the upper template 1. The No. 1 template 3 is fixed with an upper bolt 10 that slides with the No. 1 vertical slide groove 8. The upper template moves upward to drive the upper linkage plate to move upward. When the upper linkage plate moves to the bottom of the No. 1 vertical slide groove and abuts against the upper bolt, the upper template moves upward to drive the upper linkage plate to move upward. When the No. 1 template moves upward, it can drive the No. 1 template to move upward; the lower linkage structure 7 includes a lower linkage plate 12 with a No. 2 vertical slide groove 11, the bottom end of the lower linkage plate 12 is fixedly connected to the No. 2 template 4, and the No. 1 template 3 is fixedly connected with a lower bolt 13 that slides with the No. 2 vertical slide groove 11. When the No. 1 template moves upward, it can drive the lower bolt to move upward. When the lower bolt moves to the top of the No. 2 vertical slide groove, it can drive the lower linkage plate to move upward. The upward movement of the lower linkage plate can drive the No. 2 template to move upward, so that all three molding cavities can be opened.

[0029] Specifically, four upper linkage plates 9 are provided and are distributed in pairs on the front and rear end surfaces of the upper template 1; four lower linkage plates 12 are provided and are distributed in pairs on the left and right end surfaces of the second template 4. The upper linkage plates and lower linkage plates are respectively provided on the front and rear sides and the left and right sides of the mold to prevent the excessive number of linkage plates on the front and rear sides of the mold from affecting the removal of the product; the two upper linkage plates 9 located on the same end surface are respectively located at the two side edges of the end surface; the two lower linkage plates 12 located on the same end surface are respectively located at the two side edges of the end surface. The upper linkage plates 9 and the lower linkage plates 12 are provided at the edges of the mold end surface to minimize the impact on the removal of the product.

[0030] Specifically, the molding cavity 5 is formed by a combination of an upper molding surface 14 and a lower molding surface 15. The upper molding surface 14 and the lower molding surface 15 are respectively provided on the upper template 1 and the lower template 2, and the upper and lower end surfaces of the No. 1 template 3 and the No. 2 template 4 are respectively provided with a lower molding surface 15 and an upper molding surface 14.

[0031] Preferably, four rectangular positioning rods 16 are fixedly connected to the bottom of the upper template 1, and the bottom ends of the positioning rods 16 sequentially penetrate the No. 1 template 3 and the No. 2 template 4 and are inserted into the lower template 2. The positioning rods can limit the position when the upper template, the No. 1 template and the No. 2 template move.

[0032] Preferably, a plurality of hot and cold flow channels 17 are further provided in the upper mold plate 1, the first mold plate 3, the second mold plate 4 and the lower mold plate 2. High-temperature steam is introduced into the hot and cold flow channels 17 to heat the upper mold plate, the first mold plate, the second mold plate and the lower mold plate, thereby achieving heating and heat preservation of the product, and coolant is introduced into the hot and cold flow channels 17 to cool the upper mold plate, the first mold plate, the second mold plate and the lower mold plate, thereby achieving cooling of the product.

[0033] Preferably, the maximum stroke of the upper bolt 10 in the No. 1 vertical slide groove 8 is equal to the maximum stroke of the lower bolt 13 in the No. 2 vertical slide groove 11, so that the distance between the upper template and the No. 1 template, and the No. 1 template and the No. 2 template can be kept consistent when the mold is opened.

[0034] The working principle of the utility model is that the three molding cavities formed by the combination of the upper template 1, the first template 3, the second template 4 and the lower template can produce three bulletproof shovel plates at a time, which can effectively improve the production efficiency of the bulletproof plug plate. The multi-layer linkage structure can drive the first template to move upward when the upper template moves upward to a certain distance, and drive the second door plate to move upward when the first template moves to a certain distance, so that the three molding cavities can be opened. It only needs to set a lifting mechanism at the upper template;

[0035] The upper template moves upward to drive the upper linkage plate to move upward. When the upper linkage plate moves to the bottom of the No. 1 vertical slide groove and abuts against the upper bolt, it can drive the No. 1 template to move upward. The No. 1 template moves upward to drive the lower bolt to move upward. When the lower bolt moves to abut against the top of the No. 2 vertical slide groove, it can drive the lower linkage plate to move upward. The lower linkage plate moves upward to drive the No. 2 template to move upward, so that all three molding cavities can be opened. The upper linkage plate and the lower linkage plate are respectively arranged on the front and rear sides and the left and right sides of the mold to prevent the number of linkage plates on the front and rear sides of the mold from being too large and affecting the removal of the product. The upper linkage plate 9 and the lower linkage plate 12 are arranged at the edge of the mold end surface to minimize the impact on the removal of the product.

[0036] The positioning rod can limit the position when the upper template, template No. 1 and template No. 2 move. The high-temperature steam introduced into the hot and cold flow channel 17 can heat the upper template, template No. 1, template No. 2 and lower template, thereby achieving heating and insulation of the product. The coolant introduced into the hot and cold flow channel 17 can cool the upper template, template No. 1, template No. 2 and lower template, thereby achieving cooling of the product. The maximum stroke of the upper bolt 10 in the No. 1 vertical slide groove 8 is equal to the maximum stroke of the lower bolt 13 in the No. 2 vertical slide groove 11, so that the distance between the upper template and template No. 1, template No. 1 and template No. 2 can be kept consistent when the mold is opened.
