[0031] As shown in Figure 1 and Figure 5 An embodiment of the utility model provides a press housing 100, which comprises a main frame 110, a driving mechanism 130, a sealing door 120 and two guide parts 140, the two guide parts 140 are located one by one in the horizontal direction (X direction) of the sealing door 120, and the two guide parts 140 are located on the left side and the right side of the sealing door 120 respectively. Figure 5On both sides of the guide section 140 (in the X direction), mounting plates 141 are provided, and the main frame 110 is along the horizontal direction ( Figure 5 Guide members 111 are provided on both sides of the mounting plate 141 (in the X direction). Each mounting plate 141 is inclinedly guided to the corresponding guide member 111. The sealing door 120 is vertically slidably engaged with the two guide parts 140. The guide part 140 is provided with a first abutting member 142, and the sealing door 120 is provided with a second abutting member 121.

[0032] The drive mechanism 130 is used to drive the sealing door 120 to move between the open state and the closed state. When the sealing door 120 is in the closed state, the second abutment 121 abuts against the first abutment 142 to drive the mounting plate 141 to tilt and guide relative to the guide member 111 so that the sealing door 120 is sealed and attached to the main frame 110.

[0033] When the drive mechanism 130 drives the sealing door 120 to rise relative to the main frame 110 so that the sealing door 120 is in the closed state, the second abutment 121 abuts against the first abutment 142 to drive the mounting plate 141 to tilt and guide relative to the guide member 111 so that the sealing door 120 is sealed and attached to the main frame 110, thereby improving the sealing performance of the press housing 100.

[0034] Please combine Figures 2 to 4 As shown, the mounting plate 141 and the guide member 111 are inclined and slidably engaged, and the relative sliding direction of the mounting plate 141 and the guide member 111 forms an angle with the vertical direction. When the drive mechanism 130 drives the sealing door 120 to rise relative to the main frame 110 so that the sealing door 120 is in the closed state, the second abutting member 121 abuts against the first abutting member 142 to drive the mounting plate 141 to slide inclined relative to the guide member 111 so that the sealing door 120 is sealed and attached to the main frame 110, thereby improving the sealing performance of the press housing 100; when the drive mechanism 130 drives the sealing door 120 to fall relative to the main frame 110 so that the sealing door 120 is in the open state, the guide part 140 is driven by its own gravity to drive the mounting plate 141 to slide in the opposite direction relative to the guide member 111 so that the sealing door 120 is away from the main frame 110 by a certain distance.

[0035] The press housing 100 provided in this embodiment of the utility model, specifically, please refer to... Figures 2 to 4As shown, the mounting plate 141 has an inclined guide hole 143. The length direction of the inclined guide hole 143 forms an angle with the vertical direction. The inclined guide hole 143 gradually approaches the guide part 140 from top to bottom. The guide member 111 is a guide pin, which is limited and slides in the inclined guide hole 143. When the drive mechanism 130 drives the sealing door 120 to rise relative to the main frame 110 to close the sealing door 120, the second abutment 121 can abut against the first abutment 142 to drive the mounting plate 141 to slide relative to the guide pin along the inclined guide hole 143 so that the sealing door 120 is sealed and attached to the main frame 110, thereby improving the sealing performance of the press housing 100; when the drive mechanism 130 drives the sealing door 120 to fall relative to the main frame 110 to open the sealing door 120, the guide part 140 is driven by its own gravity to drive the mounting plate 141 to slide in the opposite direction relative to the guide member 111 along the inclined guide hole 143 so that the sealing door 120 is away from the main frame 110 by a certain distance.

[0036] Of course, it is understood that in another embodiment, a positioning pin may be provided on the mounting plate 141 and the guide member 111 may be an inclined guide groove opened on the side of the main frame 110. This structure can also make the mounting plate 141 and the guide member 111 slide in an inclined guide manner.

[0037] In one specific embodiment, please refer to Figures 5 to 6 As shown, the guide pin includes a fixing post 112 and a fixing pin 113. The fixing post 112 is detachably mounted on the side of the main frame 110. The connecting end of the fixing pin 113 passes through the inclined guide hole 143 and is connected to the fixing post 112. The mounting plate 141 is positioned between the limiting ends of the fixing post 112 and the fixing pin 113. The mounting plate 141 being positioned between the limiting ends of the fixing post 112 and the fixing pin 113 allows the guide pin to slide within the inclined guide hole 143 and prevents the mounting plate 141 from detaching from the guide pin, thereby preventing the guide part 140 from falling off the main frame 110.

[0038] In this embodiment, the first end of the fixing post 112 is installed on the side of the main frame 110 by thread engagement, and the connecting end of the fixing pin 113 passes through the inclined guide hole 143 and is threadedly connected to the second end of the fixing post 112.

[0039] The press housing 100 provided in this embodiment of the utility model, further, please refer to... Figures 5 to 6As shown, a rolling bearing 114 is fitted onto the fixing pin 113, and the fixing pin 113 contacts the inner wall of the inclined guide hole 143 through the rolling bearing 114. The contact between the fixing pin 113 and the inner wall of the inclined guide hole 143 via the rolling bearing 114 results in a rolling contact, thereby reducing the friction between the fixing pin 113 and the inner wall of the inclined guide hole 143 and improving the smoothness and stability of the fixing pin 113's movement relative to the inclined guide hole 143.

[0040] The press housing 100 provided in this embodiment of the utility model, further, please refer to... Figures 5 to 6 As shown, an adjusting shim 115 is provided between the mounting plate 141 and the limiting end of the fixing pin 113. The adjusting shim 115 can adjust the distance between the mounting plate 141 and the limiting end of the fixing pin 113, and at the same time reduce the friction between the limiting ends of the mounting plate 141 and the fixing pin 113, thereby reducing the wear of the limiting ends of the mounting plate 141 and the fixing pin 113 and extending the service life of the mounting plate 141 and the fixing pin 113.

[0041] In one specific embodiment, please refer to Figures 5 to 6 As shown, a vertical guide groove 144 is provided on the guide portion 140, and a vertical guide member is provided on the side of the sealing door 120. The vertical guide member is slidably fitted within the vertical guide groove 144, and the vertical guide member on the sealing door 120 is vertically slidably fitted with the vertical guide groove 144 on the guide portion 140. In another specific embodiment, a vertical guide groove 144 is provided on the side of the sealing door 120, and a vertical guide member is provided on the guide portion 140. The vertical guide member is slidably fitted within the vertical guide groove 144, and the vertical guide member on the guide portion 140 is vertically slidably fitted with the vertical guide groove 144 on the sealing door 120. In this embodiment, the guide portion 140 can be a standard profile or made of other parts with vertical guide grooves 144, and the vertical guide member is the second abutment member 121.

[0042] The press housing 100 provided in this embodiment of the utility model, further, please refer to... Figure 1As shown, the guide portion 140 is provided with a third abutment 145, and the sealing door 120 is provided with a fourth abutment 122. When the drive mechanism 130 drives the sealing door 120 to descend relative to the main frame 110 so that the sealing door 120 is in the open state, the fourth abutment 122 can abut against the third abutment 145 so that the sealing door 120 is supported and placed on the guide portion 140. When the drive mechanism 130 drives the sealing door 120 to descend relative to the main frame 110, the guide portion 140 is driven by its own gravity to drive the mounting plate 141 to slide in the opposite direction relative to the guide member 111 along the inclined guide hole 143. The drive mechanism 130 drives the sealing door 120 to continue to descend relative to the main frame 110 until the fourth abutment 122 abuts against the third abutment 145. At this time, the sealing door 120 is supported and placed on the guide portion 140, and the drive mechanism 130 no longer needs to provide pulling force to the sealing door 120. This structure can prevent the sealing door 120 from falling and causing a safety accident when the drive mechanism 130 no longer provides pulling force to the sealing door 120. In this embodiment, the second abutment 121 and the fourth abutment 122 are both slidably engaged in the vertical guide groove 144.

[0043] In one specific embodiment, please refer to Figure 6 As shown, the sealing door 120 is provided with a sealing strip 123, which allows the sealing door 120 to be sealed and attached to the main frame 110. When the drive mechanism 130 drives the sealing door 120 to rise relative to the main frame 110 to close the sealing door 120, the second abutment 121 abuts against the first abutment 142 to drive the mounting plate 141 to slide relative to the guide pin along the inclined guide hole 143, so that the sealing door 120 is sealed and attached to the main frame 110 by compressing the sealing strip 123, thereby further improving the sealing performance of the press housing 100. In this embodiment, the sealing strip 123 is a rubber sealing strip 123.
