DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0038] It should be further understood that the term "and / or" used in the present description and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0039] See also Figures 1 to 4 The zinc alloy forming mold includes a mold body 10, a sloping roof structure 20, a push plate 12, a hot runner system 80, and a temperature control system. The mold body 10 has a plurality of mold cavities, and the zinc alloy metal melt is injected into the mold cavity to form a product. The hot runner system 80 is connected to the mold body 10, and the hot runner system 80 is used to inject the zinc alloy metal melt into the mold cavity of the mold body 10. The push plate 12 is located on one side of the mold body 10. There are multiple sloping roof structures 20, each of which corresponds to a mold cavity. One end of the sloping roof structure 20 can movably penetrate the mold body 10 and extend into the mold body 10. The position of this end corresponds to the position of the mold cavity, and the other end of the sloping roof structure 20 faces and contacts the push plate 12. When the zinc alloy forming mold is demolded, the push plate 12 is on the hydraulic ejector column ( Figure 1 The push plate 12 pushes the inclined top structure 20 to move toward the mold body 10, thereby ejecting the product 50 in the mold cavity. The temperature control system is used to control the temperature of the mold body 10 and the inclined top structure 20.

[0040] See also Figure 2 and Figure 3The mold body 10 includes a front mold 11 and a rear mold 13. The front mold 11 includes a front model cavity, and the rear mold includes a rear model cavity. The front model cavity has multiple cavities, and the rear model cavity has multiple cavities. When the rear mold 13 is molded with the front mold 11, the rear model cavity and the front model cavity form a mold cavity for molding the product 50. The rear mold 13 is also provided with a slide block 131. When the product 50 is demolded, the slide block 131 needs to be offset so that the product 50 can be ejected smoothly. When the front mold 11 is molded with the rear mold 13, a plurality of liquid flow channels 132 are also formed in the zinc alloy molding mold, and each liquid flow channel 132 is connected to a mold cavity so that molten metal can be injected into the mold cavity through the liquid flow channel 132. It should be noted that the molten metal mentioned above and the molten metal mentioned later can both be zinc alloy molten metal, and the zinc alloy molten metal molds the product 50 in the mold cavity. The product 50 mentioned above and the product 50 mentioned below can both be zinc alloy castings obtained by molding zinc alloy metal melt in a mold cavity.

[0041] See also Figure 2 and Figure 5 Figure 6 , each liquid flow channel 132 is arranged in the same plane, and the liquid infusion direction of the hot nozzle 81 is perpendicular to the plane where the liquid flow channel 132 is located. Specifically, when the front mold 11 and the rear mold 13 are matched, a guide cavity 133 is formed inside the mold body 10, and the hot nozzle 81 is connected to the liquid flow channel 132 through a guide cavity 133. The molten metal enters the guide cavity 133 from the hot nozzle 81, and then is diverted from the guide cavity 133 to multiple liquid flow channels 132.

[0042] The liquid flow channel 132 includes a front section flow channel 135 and a rear section flow channel 136. The front section flow channel 135 extends in an arc shape. Specifically, the front section flow channel 135 extends in an arc shape on the parting surface of the rear mold 13, which is conducive to improving the smoothness of the flow of the molten metal and can reduce the probability of the molten metal being drawn into the air; the liquid inlet end of the front section flow channel 135 is connected to the liquid discharge port of the hot nozzle 81. The liquid inlet end of the rear section flow channel 136 is connected to the liquid discharge end of the front section flow channel 135, and the liquid discharge end of the rear section flow channel 136 is connected to the mold cavity. The rear section flow channel 136 extends along the tangent direction of one end of the front section flow channel 135 away from the hot nozzle 81, which improves the smoothness of the molten metal in the process of flowing from the front section flow channel 135 to the rear section flow channel 136, and can reduce the probability of the molten metal being drawn into the air. The cross-sectional area of ​​the front section flow channel 135 gradually decreases along the direction of liquid infusion. As the molten metal in the front section flow channel 135 flows, the speed of the molten metal will be lost, and the cross-sectional area of ​​the front section flow channel 135 is gradually reduced, ensuring that the molten metal is in an accelerated state during the filling process, which is beneficial for the molten metal to fully enter each mold cavity for molding, thereby improving the quality of the product 50.

[0043] See also Figure 5 and Figure 6 The hot runner system 80 includes a manifold 82, an inner cavity 83 is formed inside the manifold 82, and the manifold 82 is provided with a liquid inlet 84 connected to the inner cavity 83, and the liquid inlet 84 is used to receive molten metal. The manifold 82 is connected to at least two hot nozzles 81, and the hot nozzles 81 are connected to the inner cavity 83 of the manifold 82 so as to guide the molten metal in the manifold 82. The front mold 11 is provided with at least two through holes 111, and at least two hot nozzles 81 respectively enter the mold body 10 from the at least two through holes 111, wherein the hot nozzles 81 are connected to the multiple mold cavities one by one through the multiple liquid flow channels 132. Specifically, the hot nozzles 81 are connected to the liquid inlet ends of the multiple liquid flow channels 132, for example, four liquid flow channels 132 are connected, and the hot nozzles 81 transport the molten metal into the mold cavity through the liquid flow channels 132; specifically, the hot nozzles 81 are connected to each liquid flow channel 132 through the guide cavity 133, and the molten metal in the hot nozzle 81 first flows into the guide cavity 133, and then the guide cavity 133 guides the molten metal to each liquid flow channel 132.

[0044] See also Figures 7 to 10 The inclined top structure 20 includes a first inclined top component 21, a second inclined top component 22, and a top seat 30, wherein the top seat 30 can be fixed to the side of the push plate 12 facing the rear mold 13 by screws. The structure of the first inclined top component 21 is the same as that of the second inclined top component 22, and the first inclined top component 21 and the second inclined top component 22 are symmetrically arranged, and the lower end of the first inclined top component 21 and the lower end of the second inclined top component 22 are both slidably connected to the upper side of the top seat 30; wherein, the end of the first inclined top component 21 away from the top seat 30 and the end of the second inclined top component 22 away from the top seat 30 can both movably penetrate the rear mold 13 and extend into the zinc alloy forming mold, and the first inclined top component 21 and the second inclined top component 22 are arranged in a trumpet shape, and the smaller end of the trumpet shape is adjacent to the top seat 30. When demolding, the push plate 12 (please refer to Figure 1 ) pushes the ejector seat 30, the ejector seat 30 pushes the first inclined ejector assembly 21 and the second inclined ejector assembly 22, and the first inclined ejector assembly 21 and the second inclined ejector assembly 22 jointly eject the product 50 in the mold cavity.

[0045] See also Figures 8 to 11The first inclined top assembly 21 includes a first top plate 211 and a first insert 212. The first top plate 211 is in the shape of a long plate. The first top plate 211 includes a first end 2113 and a second end 2112 opposite to each other. The first end 2113 and the second end 2112 are located at two ends of the length direction of the first top plate 211. The first end 2113 can movably penetrate the rear mold 13 and extend into the mold body 10. The second end 2112 is slidably connected with the top seat 30. In a feasible solution, a slide groove 31 is provided on the upper side of the top seat 30. Specifically, the slide groove 31 is located on the side of the top seat 30 away from the push plate 12. The cross section of the slide groove 31 is T-shaped. The second end 2112 is provided with a T-shaped first slider 2111. The first slider 2111 can slide along the slide groove 31. The first top plate 211 is slidably connected with the slide groove 31 through the first slider 2111, thereby realizing the sliding connection between the first inclined top assembly 21 and the slide groove 31. The first insert 212 is detachably connected to the side of the first end 2113 facing the second lift assembly 22 to facilitate replacement of the first insert 212. When the zinc alloy is molded into a casting mold, the first insert 212 forms a side wall of the mold cavity.

[0046] See also Figure 8 The first top plate 211 is tilted to the top seat 30 , the second end 2112 of the first top plate 211 is angled to the top seat 30 , and the first end 2113 of the first top plate 211 obliquely penetrates the rear mold 13 .

[0047] See also Fig.11 A first recess 2114 is provided on the side of the first end 2113 facing the mold cavity, and the first insert 212 is installed in the first recess 2114 to limit the first insert 212 and improve the installation accuracy of the first insert 212.

[0048] The first recess 2114 is L-shaped and can position the first insert 212 to improve the installation accuracy of the first insert 212 .

[0049] See also Figures 11 to 15The first insert 212 includes a vertical first abutment surface 2123 and a horizontal second abutment surface 2125. The first insert 212 includes a first protrusion 2124. The first protrusion 2124 is T-shaped and is arranged on the first abutment surface 2123. Specifically, the first insert 212 includes a first main body portion 2121. The first vertical portion 2122 is provided on the side of the first main body portion 2121 facing the second end 2112. The first abutment surface 2123 is formed on the side of the first main body portion 2121 facing the first top plate 211. The first constituting surface 2127 is formed on the side of the first main body portion 2121 away from the first top plate 211. The first constituting surface 2127 constitutes the side wall of the mold cavity. The first constituting surface 2127 is provided with a first ejection position 2131 to eject the product 50 during demolding.

[0050] The length direction of the first insert 212 is perpendicular to the length direction of the first top plate 211 .

[0051] The first insert 212 has first holes 2133 at both ends in the length direction, and the first holes 2133 are located on the side of the first insert 212 away from the first constituent surface 2127; the first insert 212 has a first channel 2132 opened inside along the length direction, one end of the first channel 2132 passes through one end wall of the first insert 212, and the first hole 2133 is connected to the first channel 2132.

[0052] A first groove 2115 is provided on the vertical side of the first recess 2114. The first groove 2115 is T-shaped. When the first insert 212 is installed in the first recess 2114, the first protrusion 2124 cooperates with the first groove 2115 and can be fixed by screws or bolts. Specifically, the first top plate 211 is provided with three holes arranged in a triangle and passing through the first groove 2115. The holes can be passed through by screws or bolts. The first insert 212 is provided with a threaded hole matching the hole on one side adjacent to the first top plate 211 so as to be threadedly connected with the screws or bolts.

[0053] See also Fig.12 and Fig.13The first ejection position 2131 includes a first portion 2128, a second portion 2129, and a third portion 2130. The second portion 2129 is formed in a stepped manner on the side of the first constituting surface 2127 away from the second end 2112. The first portion 2128 and the third portion 2130 are formed on both sides of the second portion 2129 in the length direction. The first portion 2128 and the third portion 2130 are both formed in a convex shape. The first portion 2128 and the third portion 2130 are located obliquely below the second portion 2129. When the zinc alloy forming mold is die-cast, the molten metal is cooled and formed along the profiles of the first portion 2128, the second portion 2129, and the third portion 2130. When the product 50 is demolded, the first portion 2128, the second portion 2129, and the third portion 2130 simultaneously apply force to the frame of the product 50, so that the force on the product 50 is more uniform, thereby preventing the product 50 from being deformed or damaged on the surface.

[0054] The second abutting surface 2125 is formed on the side of the first vertical portion 2122 facing the second end 2112; the first abutting surface 2123 abuts against the vertical side surface of the first recess 2114, and the second abutting surface 2125 abuts against the lateral side surface of the first recess 2114. The first insert 212 is limited by two surfaces to achieve better positioning of the first insert 212. Further explanation, in order to ensure the size requirements of the mold cavity, when processing the first insert 212, the accuracy requirements for the first component surface 2127 of the first insert 212 are relatively high. Since the technical solution can grind and polish the first component surface 2127 and the first abutting surface 2123 at the same time, the allowable processing errors of the first component surface 2127 and the first abutting surface 2123 can be appropriately relaxed to reduce the processing difficulty.

[0055] See also Figure 8 , Fig. 9 and Fig.16The second inclined top assembly 22 includes a second top plate 221 and a second insert 222. The second top plate 221 is in the shape of a long plate. The second top plate 221 includes a third end 2213 and a fourth end 2212 opposite to each other. The third end 2213 and the fourth end 2212 are respectively located at two ends of the length direction of the second top plate 221. The third end 2213 can movably penetrate the rear mold 13 and extend into the mold body 10. The fourth end 2212 is slidably connected to the top seat 30. In a feasible solution, the fourth end 2212 is provided with a T-shaped second slider 2211. The second slider 2211 can slide along the slide groove 31. The second top plate 221 is slidably connected to the slide groove 31 through the second slider 2211, thereby realizing the sliding connection between the second inclined top assembly 22 and the slide groove 31. The second insert 222 is detachably connected to the side of the third end 2213 facing the first inclined top assembly 21 to facilitate the replacement of the second insert 222. When the zinc alloy is molded into a casting mold, the second insert 222 is arranged opposite to the first insert 212, and the second insert 222 and the first insert 212 constitute two opposite side walls of the mold cavity. This can be understood as: the first insert 212 and the second insert 222 form two opposite side walls of the mold cavity, and the lower side wall, the upper side wall and the other two peripheral side walls of the mold cavity are formed by the rear mold 13 and the front mold 11.

[0056] The second top plate 221 is arranged obliquely with respect to the top seat 30, and the third end 2213 of the second top plate 221 obliquely penetrates the rear mold 13, and the angle between the second top plate 221 and the top seat 30 is set. The second top plate 221 has the same structure as the first top plate 211. The second top plate 221 and the first top plate 211 are arranged in a trumpet shape, so that the first inclined top assembly 21 and the second inclined top assembly 22 are arranged in a trumpet shape, and the smaller end of the trumpet shape faces the top seat 30, and the first end 2113 and the second end 2112 are located at the larger end of the trumpet shape, which can reduce the installation distance between the rear mold 13 and the push plate 12, which is beneficial to reduce the size of the zinc alloy forming mold. It is further explained that the angle between the first top plate 211 and the second top plate 221 can range from 8° to 16°. During demoulding, the push plate 12 pushes the top seat 30, and the top seat 30 pushes the first top plate 211 and the second top plate 221 to move toward the front mold 11. Under the limit of the rear mold 13, the distance between the first end 2113 of the first top plate 211 and the third end 2213 of the second top plate 221 gradually increases. Synchronously, the second end 2112 of the first top plate 211 and the fourth end 2212 of the second top plate 221 move along the slide groove 31, and the distance between the second end 2112 and the fourth end 2212 gradually increases. Driven by the first top plate 211 and the second top plate 221, the first insert 212 and the second insert 222 move toward the front mold 11. At the same time, the distance between the first insert 212 and the second insert 222 also gradually increases. Therefore, while the product 50 is ejected toward the front mold 11, the product 50 is also loosened from the first insert 212 and the second insert 222, making it easy to take out the product 50.

[0057] See also Figures 16 to 19 A second recess 2214 is formed on the side of the third end 2213 facing the first top plate 211 , and the second insert 222 is installed in the second recess 2214 to limit the position of the second insert 222 .

[0058] The second recess 2214 is L-shaped, and the second recess 2214 can be used to position the second insert 222 .

[0059] The second insert 222 has the same structure as the first insert 212. The second insert 222 includes a vertical third abutting surface 2223, a horizontal fourth abutting surface 2225 and a second constituting surface 2227.

[0060] Further explanation, in order to ensure the size requirements of the mold cavity, when processing the second insert 222, the second component surface 2227 of the second insert 222 has a high precision requirement. Since the technical solution can grind and polish the second component surface 2227 and the third abutting surface 2223 at the same time, the allowable processing error of the second component surface 2227 and the third abutting surface 2223 can be appropriately relaxed to reduce the processing difficulty.

Each pipe mentioned in the present application can be injected with heat transfer oil, and the side wall of the pipe exchanges heat with the heat transfer oil in the pipe. The first pipe 14 and the second pipe 151 are arranged in the front mold 11 to exchange heat with the front mold 11; the front mold 11 is provided with holes for inserting the first pipe 14 and the second pipe 151.

[0065] See also Fig. 20 In one embodiment, the number of the first pipes 14 is four, and every two first pipes 14 are symmetrically arranged on both sides of the through hole 111; the number of the second pipes 151 is one; the number of the third pipes 16 is four, and every two third pipes 16 are symmetrically arranged on both sides of the through hole 111, and the number of the fifth pipes 215 is two.

[0066] The first pipe 14 includes a first heat conducting section 143, a second heat conducting section 142, and a third heat conducting section 141. The two ends of the first heat conducting section 143 are connected to the second heat conducting section 142 and the third heat conducting section 141 respectively. The liquid inlet end and the liquid discharge end of the first pipe 14 are respectively arranged at the second heat conducting section 142 and the third heat conducting section 141. The liquid inlet end of the first pipe 14 is arranged at the second heat conducting section 142, and the liquid discharge end of the first pipe 14 is arranged at the third heat conducting section 141. The heat conducting oil enters from the second heat conducting section 142, then flows through the first heat conducting section 143, and finally flows out from the third heat conducting section 141. The first heat conducting section 143 abuts against the side wall of the through hole 111 so as to perform heat exchange with the side wall of the through hole 111. The first heat conducting section 143 may be a spiral tube spirally wound along the circumferential direction of the through hole 111, or may be a plate or other shapes. In one embodiment, the first heat conducting section 143 is an arc-shaped plate extending along the circumferential direction of the through hole 111, so that the contact area between the first heat conducting section 143 and the side wall of the through hole 111 can be increased to obtain a more efficient heat exchange efficiency. The first heat conducting section 143 is provided with an arc-shaped plate-shaped inner cavity 83 matching the outer profile of the first heat conducting section 143, so that the heat conducting oil in the first heat conducting section 143 can be better and more efficiently heat exchanged with the first heat conducting section 143.

[0067] During die-casting of the zinc alloy forming mold, heat transfer oil is injected into the second heat transfer section 142, and the heat transfer oil flows through the first heat transfer section 143 and finally flows out from the third heat transfer section 141; when the heat transfer oil just enters the second heat transfer section 142, it has a relatively high heat content. When the heat transfer oil flows in the second heat transfer section 142, the heat is transferred to the front mold 11 through the tube wall of the second heat transfer section 142, so as to increase the temperature of the front mold 11. During this transmission stage, the heat content of the heat transfer oil will decrease; since the hot nozzle 81 has a relatively high temperature, the heat of the hot nozzle 81 is transferred to the side wall of the through hole 111, so the temperature near the through hole 111 is higher than the temperature of other parts of the front mold 11. When the heat transfer oil flows into the first heat transfer section 143, the heat of the side wall of the through hole 111 is transferred to the heat transfer oil through the tube wall of the first heat transfer section 143, increasing the heat content of the heat transfer oil and also reducing the temperature of the side wall of the through hole 111; when the heat transfer oil flows into the third heat transfer section 141, The heat of the heat-conducting oil is transferred to the front mold 11 through the tube wall of the third heat-conducting section 141, thereby increasing the temperature of the front mold 11. Therefore, the heat-conducting oil flows through the second heat-conducting section 142, the first heat-conducting section 143, and the third heat-conducting section 141, thereby increasing the temperature of the front mold 11 and balancing the temperatures of various parts of the front mold 11.

In a feasible solution, the shape of the first outer frame is a square frame with three borders, and the positive projection formed by the first outer frame on the first plane is a square frame with three borders. The second heat conducting section 142 can heat or cool the back side of the first front mold cavity 112 more evenly, thereby adjusting the temperature of the first front mold cavity 112. In order to obtain a better temperature adjustment effect for the first front mold cavity 112 , the distance between the first plane and the second plane is two to three times the diameter of the tube section of the second heat conducting section 142 .
