Structure for preventing center distance deviation of multi-hole paper pulp molded product

Abstract

This utility model relates to a structure for preventing center distance misalignment in multi-cavity pulp molding products. It includes a support mold, the main body of which is a rectangular plate structure. A waste edge groove with a one-way opening at the top surface of the support mold is provided. This addresses the problem that in existing products, uneven internal stress distribution during the stress release stage after demolding easily leads to product deformation, resulting in center distance misalignment in the semi-finished product. This center distance misalignment causes serious problems in subsequent edge trimming processes, resulting in uneven edges after trimming. By setting a clearance groove on the support mold, space is provided for product stress release, greatly reducing deformation caused by uneven stress. Simultaneously, the groove provides precise positioning of the molded product and protects the skirt, ensuring product stability during the molding process from multiple aspects and effectively preventing center distance misalignment. This avoids the problem of uneven edges in the subsequent edge trimming process.

Description

Technical Field

[0001] This utility model relates to the field of pulp molding product technology, and in particular to a structure for preventing the center distance of multi-cavity pulp molding products from shifting. Background Technology

[0002] To improve production efficiency and mold space utilization, companies generally adopt multi-cavity integrated mold structures with more than 10 cavities, enabling the simultaneous production of multiple products on the same mold table, which significantly shortens the production cycle of a single product.

[0003] However, due to the inherent characteristics of pulp molded products, they are highly susceptible to deformation during the stress release phase after demolding due to uneven internal stress distribution. This deformation leads to a shift in the center distance of the semi-finished product, causing serious consequences in subsequent edge trimming processes. This center distance shift results in uneven edges after trimming, causing dimensions to fail to meet standard requirements, resulting in a large number of defective products. This not only increases raw material and labor costs, but frequent rework also reduces overall production efficiency, severely impacting the company's economic benefits. Currently, there is no effective solution in the industry for the center distance shift problem in multi-cavity pulp molded products. Existing technologies are insufficient to meet the demands of high-quality, high-efficiency production, necessitating the development of new technologies to overcome this predicament.

[0021] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-6 As shown, this embodiment provides a structure to prevent the center distance of multi-cavity pulp molding products from shifting, including a bearing mold 1. The main body of the bearing mold 1 is a rectangular plate structure. A waste edge groove 101 with a one-way opening at the top is provided on the top surface of the bearing mold 1. An anti-cavity groove 1011 is also provided in a straight line array on the inner top surface of the bearing mold 1. The anti-cavity groove 1011 has a two-way through structure on the upper and lower sides. The inner side of the support mold 1 is also provided with a straight array of slots 1012 that are bidirectionally connected on both the upper and lower sides. A clearance slot 1011 is provided between the slots 1012. A molded product 1013 is placed inside the slots 1012. A skirt 1014 is fixedly connected to the outer side of the molded product 1013. The skirt 1014 is used to be placed above the support mold 1.

[0022] Among them, a support mechanism 2 is fixedly connected to the bottom end face of the bearing mold 1. There are four support mechanisms 2 in total. Each pair of horizontally adjacent support mechanisms 2 forms a group. The two groups of support mechanisms 2 are fixedly connected to the front and rear sides of the bottom end face of the bearing mold 1 in a longitudinal array. The inner side of the two groups of support mechanisms 2 is fixedly connected to a longitudinally arranged support plate 201. By incorporating a waste edge groove 101 and a clearance groove 1011 into the bearing mold 1, space can be provided for stress release during product molding, reducing deformation caused by uneven stress. The retaining groove 1012 on the inner side of the bearing mold 1 is used to place the molded product 1013, and the skirt 1014 is placed above the bearing mold 1, serving to initially position and protect the molded product 1013. Simultaneously, the four support mechanisms 2 at the bottom of the bearing mold 1, arranged in pairs laterally, can stably support the bearing mold 1, ensuring the stability of the product during processing.

[0023] Among them, the support plate 201 has two mounting holes 2011 arranged in a longitudinal array inside. The mounting holes 2011 are used to install fixing bolts and limit the support plate 201. The support mechanism 2 has a longitudinal groove inside, which is a guide groove 2012. An adjusting rod 3 is rotatably connected inside the guide groove 2012. Two sets of support mechanisms 2 are longitudinally arrayed and fixed to the front and rear sides of the bottom surface of the bearing mold 1. The support plate 201 on the inner side further enhances the support stability of the bearing mold 1. The mounting holes 2011 inside the support plate 201 can be used to install fixing bolts to limit the support plate 201, prevent its displacement, ensure the stability of the entire support structure, and thus ensure the stability of the product during processing on the bearing mold 1, which helps to improve the product molding quality.

[0024] The adjusting rod 3 is a lead screw structure, and the top of the adjusting rod 3 extends upward to form a support mechanism 2. A knob 301 is fixedly connected to the top surface of the adjusting rod 3. Anti-slip grooves are arranged in a ring array on the outer circumference of the knob 301. The knob 301 and the adjusting rod 3 together form a rotation adjustment structure. The supporting mechanism 2 is internally connected to a moving component 3011 that slides up and down. The moving component 3011 is arranged horizontally, and four sliders 3012 with protruding structures are fixedly connected to the outer side of the moving component 3011 in opposite directions. Each pair of vertically adjacent sliders 3012 forms a group, and the two groups of sliders 3012 are arranged in a linear array. The moving component 3011 has a screw hole inside that matches the adjusting rod 3. A guide post assembly 3013 is fixedly connected to the top surface of the moving component 3011. The guide post assembly 3013 is located directly below the molded product 1013. The adjusting rod 3, connected to the lead screw structure, is rotatably connected via the guide groove 2012 inside the support mechanism 2. The top end of the adjusting rod 3 extends out of the support mechanism 2 and connects to the knob 301. Rotating the knob 301 can drive the adjusting rod 3 to rotate, facilitating adjustment by the operator and providing convenience for subsequent adjustment of the position of the moving component 3011 using the adjusting rod 3.

[0025] In use, during the production of pulp molded products, the pulp raw material is placed on the carrier mold 1. The main body of the carrier mold 1 is a rectangular plate structure. The waste groove 101 on its top surface is used to collect excess pulp waste during the product molding process. The inner top surface of the carrier mold 1 has a linear array of clearance grooves 1011, which are bidirectional through-hole structures on both the top and bottom sides. During the product molding process, because pulp molded products are easily affected by the environment, internal stress will be generated. The existence of clearance grooves 1011 provides space for the product during the stress release stage, allowing the internal stress of the product to be released more evenly and avoiding stress concentration. The product deforms, and the slots 1012 arranged in a straight array on the inner side of the support mold 1 are used to place the molded product 1013. The slots 1012 are bidirectionally open on both the upper and lower sides to facilitate the drainage of moisture and air circulation during the molding process. The skirt 1014 fixedly connected to the outer side of the molded product 1013 is placed above the support mold 1. The skirt 1014 plays a preliminary positioning role for the molded product 1013 to ensure that the molded product 1013 is accurately positioned on the support mold 1. On the other hand, the skirt 1014 can also protect the molded product 1013 to a certain extent and prevent its edges from being damaged during processing. Four support mechanisms 2 are fixedly connected to the bottom surface of the support mold 1. Each pair of horizontally adjacent support mechanisms 2 forms a group. The two groups of support mechanisms 2 are fixedly connected to the front and rear sides of the bottom surface of the support mold 1 in a longitudinal array. This layout allows the support mold 1 to remain stable during placement and use, avoiding the impact of product molding quality caused by the shaking of the support mold 1. The inner side of the two groups of support mechanisms 2 is fixedly connected to a longitudinally arranged support plate 201. The support plate 201 further enhances the support stability of the support mold 1. The support plate 201 has two mounting holes 2011 arranged in a longitudinal array inside. The support plate 201 can be fixed to other equipment or workbench by mounting bolts, limiting the support plate 201 and preventing it from shifting, thereby ensuring the stability of the entire support structure and providing a stable foundation for the processing of products on the support mold 1. The support mechanism 2 has a longitudinal guide groove 2012 inside. A lead screw structure adjusting rod 3 is rotatably connected inside the guide groove 2012. The top of the adjusting rod 3 extends upwards out of the support mechanism 2, and a knob 301 is fixedly connected to its top surface. The outer circumference of the knob 301 has an annular array of anti-slip grooves for easy gripping and rotation by the operator. When the operator rotates the knob 301, the adjusting rod 3 rotates accordingly. Since the adjusting rod 3 is a lead screw structure, and the moving component 3011 has a matching screw hole inside, four opposing sliders 3012 are fixedly connected to the outer side of the moving component 3011. Every two longitudinally adjacent sliders 3012 form a group, and the two groups of sliders 3012 are in a straight line. The array configuration allows the slider 3012 to cooperate with the guide groove 2012, enabling the moving component 3011 to slide up and down within the guide groove 2012 when the adjusting rod 3 rotates. The guide post component 3013, fixedly connected to the top surface of the moving component 3011, is located directly below the molded product 1013. By adjusting the up and down position of the moving component 3011, the relative positional relationship between the guide post component 3013 and the molded product 1013 can be adjusted. During the product molding process, the moving component 3011 can be moved by rotating the knob 301 and using the adjusting rod 3, according to actual needs. This allows the guide post component 3013 to support the molded product 1013 and perform fine-tuning of its position, further ensuring the stability of the product's center distance and preventing center distance deviation.
