Description

Technical Field

[0001] The utility model relates to the technical field of cylinder heads, specifically a production device for automobile engine cylinder heads. Background Technique

[0002] The production of automobile engine cylinder heads is a complex process involving multiple steps and technologies. The production of cylinder heads first requires casting. Molding sand is added to the upper and lower seats of the core mold, and pressure is applied using a pressing machine. After melting the heat-treated cast iron, it is poured into the pre-made sand mold, and after cooling and solidifying, the preliminary shape of the cylinder head is formed. Subsequently, finishing and surface treatment and other processes are carried out. When some existing small manufacturers apply pressure to the upper and lower seats of the core mold using a pressing machine, there is no limiting structure for the core mold on some operation panels of the pressing machine. During pressurization, the core mold may shift due to the pressure, resulting in the overflow and scattering of the molding sand. After pressurization is completed, when separating the core mold, some use manual methods such as prying it open with a hammer and then slowly knocking it to separate. The number of force application points during knocking is small, making it easy to have uneven demolding, and the force is difficult to control. If the mold slips out of the hand and falls on the table, it is easy to cause an impact on the core and lead to damage, which is not convenient to use. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1 to 4, in the embodiment of the present utility model, a production device for an automobile engine cylinder head includes a pressurizing mechanism 10. The pressurizing mechanism 10 includes a pressurizing machine body 11. An operating plate body 12 is slidably connected inside the pressurizing machine body 11. Two placing frames 13 are symmetrically and fixedly connected to the front side of the pressurizing machine body 11. Two clamping seats one 121 are symmetrically and fixedly connected to the top of the operating plate body 12. Two clamping seats two 122 for limiting the lower seat 21 of the core mold are slidably connected to the top of the operating plate body 12. A fixing plate 14 is slidably connected to the bottom of the placing frame 13. A regulating frame 141 is slidably connected to the top of the fixing plate 14. Two limiting shells 15 are slidably connected to the front side of the pressurizing machine body 11. Two elliptical blocks 151 are rotatably connected inside the limiting shell 15. A driving module 16 for driving the two elliptical blocks 151 to rotate synchronously is arranged inside the limiting shell 15.

[0021] Specifically, by rotatably connecting a plurality of elliptical blocks 151 inside the limiting shell 15, rotating the one-way lead screw one 127 to drive the clamping seat two 122 to be clamped with the lower seat 21 of the core mold, the clamping seat one 121 and the clamping seat two 122 can cooperate to stably limit the clamping seat two 122, preventing the lower seat 21 of the core mold from shifting during pressurization. Starting the hydraulic rod 163 to drive the limiting shell 15 to move upward can drive the two elliptical blocks 151 to rotate synchronously, so that when the elliptical blocks 151 push the regulating frame 141 to move upward as a whole, they can move up and down, driving the regulating frame 141 to reciprocally push the upper seat 20 of the core mold, making the upper seat 20 of the core mold separate from the lower seat 21 of the core mold more smoothly, with a higher integrity of core demolding, saving manpower and being convenient to use.

[0022] Embodiment 1

[0023] As Figures 1-2 shown, in this embodiment, two support seats 123 are fixedly connected to the top of the operating plate body 12. The support seats 123 are fixedly connected to the bottom of the adjacent clamping seat one 121. Two limiting seats 124 are arranged on the top of the operating plate body 12. The limiting seats 124 are fixedly connected to the bottom of the adjacent clamping seat two 122. A limiting rod 125 is fixedly connected to one side of the support seat 123. The limiting rod 125 penetrates through the adjacent limiting seat 124 and is slidably connected to it. A U-shaped seat 126 is slidably connected inside the operating plate body 12. The two ends of the U-shaped seat 126 are respectively fixedly connected to the bottom of the adjacent limiting seat 124. A one-way lead screw one 127 is rotatably connected inside the operating plate body 12. The one-way lead screw one 127 penetrates through the U-shaped seat 126 and is in threaded connection with it. A regulating screw 128 is fixedly connected to the front end of the one-way lead screw one 127.

[0024] In this embodiment, the first clamping seat 121 is fixed by the support seat 123, and the sliding limit of the second clamping seat 122 is realized by the limit of the limit seat 124 by the limit rod 125. After the lower seat 21 of the core mold can be clamped inside the first clamping seat 121 and the second clamping seat 122, the regulating screw 128 is rotated to drive the first one-way lead screw 127 to rotate, so as to drive the U-shaped seat 126 to drive the two second clamping seats 122 to be clamped with the lower seat 21 of the core mold, so as to stably limit the lower seat 21 of the core mold.

[0025] As Figure 3 shown, in this embodiment, two support frames 131 are symmetrically and fixedly connected to the front side of the press body 11. The support frame 131 is fixedly connected to the bottom of the adjacent placement frame 13. A vertical plate 142 is fixedly connected to the top of the fixed plate 14. A horizontal plate 143 is fixedly connected to the front side of the press body 11. A double-shaft motor 144 is fixedly connected to the bottom of the horizontal plate 143. One-way lead screws 145 are rotatably connected to the opposite sides of the two placement frames 13. The one-way lead screw 145 penetrates through the adjacent fixed plate 14 and is in threaded connection with it. The two output ends of the double-shaft motor 144 are respectively fixedly connected to the adjacent one-way lead screws 145.

[0026] During specific implementation, the bottom of the placement frame 13 is supported by the support frame 131, so that the overall support frame 131 is more stable. When driving the two regulating frames 141 to be inserted into the upper seat 20 of the core mold, it stops until the vertical plate 142 contacts the upper seat 20 of the core mold, so as to assist in positioning the position of the regulating frame 141, and the two vertical plates 142 can be more stable when separating the upper seat 20 of the core mold upward. The double-shaft motor 144 is fixed by the horizontal plate 143. The double-shaft motor 144 is started to drive the two one-way lead screws 145 to rotate synchronously, so as to drive the two fixed plates 14 to drive the regulating frame 141 to move horizontally, drive the two regulating frames 141 to approach or move away synchronously, and assist in limiting the upper seat 20 of the core mold by the clamping connection between the regulating frame 141 and the upper seat 20 of the core mold.

[0027] Embodiment Two

[0028] On the basis of Embodiment One, in order to facilitate the smoother and more stable separation of the upper seat 20 of the core mold from the lower seat 21 of the core mold.

[0029] As Figures 3-4As shown in the figure, in this embodiment, two shaft rods 152 are rotatably connected to the inner top wall of the limit housing 15. The shaft rods 152 penetrate through the adjacent elliptical blocks 151 and are fixedly connected thereto. The driving module 16 includes two fixed housings 161 fixedly connected to the front side of the press body 11. A rack 162 is fixedly embedded in the front side of the fixed housing 161. Clamping plates 153 are fixedly connected to the outer walls of both sides of the limit housing 15. The clamping plates 153 are slidably connected to the adjacent limit housing 15. A round rod 164 and a power rod 166 are rotatably connected to the inner top surface of the limit housing 15. A plurality of second bevel gears 165 are fixedly sleeved on the outer wall of the round rod 164. A first bevel gear 154 is fixedly sleeved at one end of the shaft rod 152. A round gear 167 and a third bevel gear 168 are fixedly sleeved on the outer wall of the power rod 166. The first bevel gear 154 and the third bevel gear 168 are both meshed with the adjacent second bevel gears 165. The round gear 167 is meshed with the adjacent rack 162. A hydraulic rod 163 is fixedly connected to the front side of the fixed housing 161. The output end of the hydraulic rod 163 is fixedly connected to the bottom of the adjacent limit housing 15.

[0030] During specific implementation, the rotation of the elliptical block 151 is limited by the shaft rod 152, and the sliding limit of the driving module 16 in the vertical direction is realized by the limit of the clamping plate 153 by the fixed housing 161. Starting the hydraulic rod 163 can lift the driving module 16. During the lifting process, the power rod 166 is driven to rotate through the transmission of the round gear 167 and the rack 162, and the round rod 164 is driven to rotate through the transmission of the third bevel gear 168 and the adjacent second bevel gears 165. Thus, through the transmission of the first bevel gear 154 and the adjacent second bevel gears 165, the two elliptical blocks 151 are driven to rotate synchronously and in the same direction, so that while the elliptical block 151 continuously pushes against the lower end of the regulation frame 141, the regulation frame 141 is integrally driven to move upward, thereby continuously hitting the upper seat 20 of the core mold and slowly and uniformly separating it from the lower seat 21 of the core mold.

[0031] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.

[0032] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
