T-shaped groove high-strength template structure

Abstract

This application relates to the field of injection molding machine mold technology and provides a high-strength T-slot template structure. In use, the mold to be installed is placed on the mounting surface, and bolts or T-bolts are used in conjunction with the T-slot structure to connect the mold to the plate. Specifically, the bolt shank passes sequentially through a circular hole, a slot, and a hole into the threaded hole of the mold. The bolt / T-bolt is tightened until the bolt nut is completely submerged in the slot, allowing the bolt / T-bolt nut to slide along the slot. Because of the slot, the bolt shank slides along the slot as the nut slides, facilitating quick and efficient mold installation. Furthermore, since the T-slot structure directly passes through the plate when connected to the mold via bolts / T-bolts, the plate as a whole bears the pressure applied by the bolts / T-bolts, resulting in more even stress distribution and less deformation compared to traditional T-slot structures.

Description

Technical Field

[0001] This application belongs to the field of injection molding machine mold technology, and in particular relates to a high-strength template structure for T-slots. Background Technology

[0002] To ensure strength during mold installation, existing injection molding machines typically drill threaded holes at varying intervals on the mold plate surface or make the mold plate thicker, and then create openings at both ends of the mold plate surface. Figure 1 The traditional T-slot structure (100) shown above will deform severely under stress when high injection speed injection or high injection pressure injection is performed, causing the mold to break open (the traditional T-slot hole is stretched open during injection), resulting in flash on the product. Alternatively, some manufacturers use the traditional die hole (threaded hole) structure to ensure strength, which has a fixed mold installation position and a complicated and inefficient installation process. Utility Model Content

[0003] This application provides a high-strength T-slot template structure, which can solve the problems of low mold installation efficiency when using traditional mold mounting holes in injection molding production, and the easy deformation of the mold during high-speed or high-pressure injection molding, which can lead to mold slippage.

[0004] This application provides a high-strength T-slot template structure for use as a moving template and / or fixed template in an injection molding machine. The high-strength T-slot template structure includes:

[0005] The plate body includes a mounting surface and a connecting surface, which are opposite to each other. The mounting surface is used for connection with the mold, and the connecting surface is used for connection with the frame / drive mechanism; and

[0006] The T-slot structure includes a circular hole, a strip groove, and a strip hole. The circular hole is a blind hole and is located on the connecting surface. The strip groove is located inside the plate, with one end connected to the circular hole and located at the center of the circular hole, and the other end of the strip groove extending away from the edge of the plate. The strip hole is located on the mounting surface corresponding to the strip groove, and the projection of the strip hole in the thickness direction of the plate is covered by the strip groove. The strip hole and the strip groove are connected.

[0007] The circular hole, the strip groove, and the strip hole are connected in sequence. The diameter of the circular hole is larger than the width of the strip hole, and the width of the strip groove is larger than the width of the strip hole.

[0008] Optionally, multiple T-slot structures are provided, symmetrically arranged on the plate with the centerline of the plate as the axis.

[0009] Optionally, four T-slot structures are provided, with two T-slot structures spaced apart on the left side of the plate and the other two T-slot structures spaced apart on the right side of the plate.

[0010] Optionally, the four corners of the plate are provided with sleeve holes for setting positioning guide sleeves. The positioning guide sleeves are used to slide with the tie rod of the injection molding machine and cooperate with the tie rod to achieve positioning.

[0011] Optionally, the plate has a center hole for the ejector pin / nozzle of the injection molding machine to pass through.

[0012] Optionally, the plate body has multiple mounting holes on the mounting surface for fixing the mold.

[0013] Optionally, a reinforcing structure is provided on the connecting surface.

[0014] Optionally, the reinforcing structure is a reinforcing block provided on the connecting surface and extending along the thickness direction of the plate. The reinforcing block is designed to avoid the T-slot structure, and a connecting mechanism is provided on the side of the reinforcing block away from the connecting surface.

[0015] Optionally, the reinforcing structure is a reinforcing rib, which avoids the T-slot structure, and a connecting mechanism is provided on the side of the reinforcing rib away from the connecting surface.

[0016] Optionally, support feet are provided at both ends of the lower side of the plate.

[0017] The high-strength T-slot template structure provided in this application involves placing the mold to be installed on the mounting surface and connecting the mold to the plate using bolts or T-bolts in conjunction with the T-slot structure. Specifically, the bolt shank passes sequentially through a circular hole, a slot, and a hole into the threaded hole of the mold. The bolt / T-bolt is tightened until the bolt nut is completely submerged in the slot, allowing the bolt / T-bolt nut to slide along the slot. Due to the slot, the bolt shank can slide along the slot as the nut slides, facilitating quick and efficient mold installation. Furthermore, because the T-slot structure directly passes through the plate when connected to the mold via bolts / T-bolts, the plate as a whole bears the pressure applied by the bolts / T-bolts, resulting in more uniform stress distribution and less deformation compared to traditional T-slot structures.

[0040] Currently, the traditional mold mounting hole method in injection molding production has low production efficiency, while the traditional T-slot structure is prone to deformation during high-speed or high-pressure injection molding, which can lead to mold derailment.

[0041] To address the aforementioned problems, one embodiment of this application provides a high-strength T-slot template structure for use as a moving template and / or fixed template in an injection molding machine, such as... Figure 2 and Figure 4As shown, the T-slot high-strength template structure includes: a plate body 1 and a T-slot structure. The plate body 1 includes a mounting surface 11 and a connecting surface 12, which are opposite to each other. The mounting surface 11 is used to connect with the mold, and the connecting surface 12 is used to connect with the frame / drive mechanism. The T-slot structure 2 includes a circular hole 21, a strip groove 22, and a strip hole 23. The circular hole 21 is a blind hole and is formed on the connecting surface 12. The strip groove 22 is disposed inside the plate body 1, and one end of the strip groove 22 is connected to the circular hole 21. The circular hole 21 is located at the center of the circular hole 21, and the other end of the strip groove 22 extends away from the edge of the plate 1. The strip hole 23 is set on the mounting surface 11 corresponding to the strip groove 22. The projection of the strip hole 23 in the thickness direction of the plate 1 is covered by the strip groove 22, and the strip hole 23 is connected to the strip groove 22. The circular hole 21, the strip groove 22 and the strip hole 23 are connected in sequence. The diameter of the circular hole 21 is larger than the width of the strip hole 23, and the width of the strip groove 22 is larger than the width of the strip hole 23.

[0042] When using the high-strength T-slot template structure provided in this application, the mold to be installed is placed on the mounting surface 11, and the mold is connected to the plate body 1 using bolts or T-bolts in conjunction with the T-slot structure 2 of this application. Specifically, the bolt shank passes through the circular hole 21, the strip groove 22, and the strip hole 23 in sequence and extends into the threaded hole of the mold. The bolt / T-bolt is tightened until the bolt nut is completely submerged in the strip groove 22, so that the bolt / T-bolt nut can slide along the strip groove 22. Because of the strip hole 23, the shank can slide along the strip hole 23 when the nut slides, thereby facilitating the quick and efficient installation of the mold. At the same time, because the T-slot structure 2 of this application directly passes through the plate body 1 when connected to the mold by bolts / T-bolts, the plate body 1 as a whole bears the pressure applied by the bolts / T-bolts, and the stress is more uniform than that of the traditional T-slot structure 100, making it less prone to deformation.

[0043] It is understood that the aforementioned molds and bolts / T-bolts are all existing structures in the prior art, and can be set up by referring to the existing structures in existing injection molding equipment, so they will not be elaborated on here.

[0044] In some embodiments of this application, such as Figure 2 and Figure 4 As shown, multiple T-slot structures 2 are provided, symmetrically arranged on plate 1 with the centerline of plate 1 as the axis.

[0045] When setting up the mold, multiple T-slot structures 2, together with bolts / T-bolts, are used to set the mold on the plate body 1, which can increase stability and prevent the mold from becoming loose during installation.

[0046] In some embodiments of this application, such as Figure 2As shown, there are four T-slot structures 2, with two T-slot structures 2 spaced apart on the left side of the plate 1 and the other two T-slot structures 2 spaced apart on the right side of the plate 1.

[0047] In some embodiments, the mold is a split mold, specifically, it is divided into a left mold and a right mold. T-slot structures 2 are provided on the left and right sides of the plate 1 to facilitate the stability of the installation of the left / right molds. The T-slot structures 2 are symmetrically arranged on the plate 1 with the center line of the plate 1 as the axis to ensure that the left and right molds in the split mold can be well assembled.

[0048] The specific structure of the aforementioned split mold can be set with reference to existing technology, and will not be elaborated on here.

[0049] In some embodiments of this application, such as Figure 2 , Figure 3 and Figure 5 As shown, the four corners of the plate 1 are provided with sleeve holes 3 for setting positioning guide sleeves (not shown in the figure). The positioning guide sleeves are used to slide with the pull rod 10 of the injection molding machine and cooperate with the pull rod 10 to achieve positioning.

[0050] The aforementioned hole 3 is used to set the positioning guide sleeve, which facilitates the positioning of the plate 1 and the sliding connection with the pull rod 10. The aforementioned positioning guide sleeve and pull rod 10 are conventional settings in injection molding machines in the prior art, so their structure will not be described in detail here.

[0051] In some embodiments of this application, such as Figures 2 to 5 As shown, a central hole 4 is provided in the center of the plate 1, which is used for the ejector pin / nozzle of the injection molding machine to pass through.

[0052] When the plate 1 of this application is used as a moving template, the above-mentioned central hole 4 is for the nozzle to pass through; when the plate 1 of this application is used as a fixed template, the above-mentioned central hole 4 is for the ejector pin to pass through.

[0053] The T-slot high-strength template structure of this application can be used as a moving template and / or a fixed template, and has high versatility. Only the connection surface 12 needs to be set as required. When the T-slot high-strength template structure of this application is used as a moving template, the connection surface 12 can be set with reference to the connection method between the moving template and the drive mechanism in the prior art (such as elbow type and hydraulic direct pressure type). It only needs to be able to connect with the drive mechanism and perform linear motion under the action of the drive mechanism to complete the mold closing function. When the T-slot high-strength template structure of this application is used as a fixed template, the connection surface 12 can be set with reference to the structure used to fix the fixed template in the frame or other injection molding machines in the prior art. It only needs to be able to be relatively fixed with the injection molding machine frame. Therefore, it will not be described in detail here.

[0054] In some embodiments of this application, such as Figure 2, Figure 4 and Figure 5 As shown, the plate 1 has multiple mounting holes 5 on the mounting surface 11 for fixing the mold.

[0055] The aforementioned mounting hole 5 is a reserved hole used for fixing certain molds in the prior art. In the prior art, some molds need to be fixed to the template by bolts or pressure plate clamps in conjunction with bolts. The setting of the aforementioned mounting hole 5 makes the T-slot high-strength template structure of this application more versatile.

[0056] In some embodiments of this application, such as Figures 2 to 4 As shown, a reinforcing structure 6 is provided on the connecting surface 12.

[0057] The aforementioned reinforced structure is used to increase the overall structural strength of the high-strength T-slot template structure of this application, enabling it to withstand greater mold closing / clamping forces during injection molding.

[0058] In some embodiments of this application, the reinforcing structure 6 is a reinforcing block (not shown in the figure) disposed on the connecting surface 12 and extending along the thickness direction of the plate 1. The reinforcing block is disposed to avoid the T-slot structure 2, and a connecting mechanism (not shown in the figure) is provided on the side of the reinforcing block away from the connecting surface 12.

[0059] The aforementioned reinforcing blocks can enhance the strength of the T-slot high-strength template structure of this application, and the connecting mechanism is used to connect with the drive mechanism / frame.

[0060] Specifically, the aforementioned connecting mechanism can be a hinge for connecting to the drive end of the drive mechanism; the aforementioned connecting mechanism can also be a flange for connecting to the drive end of the drive mechanism / connecting to the frame.

[0061] It is understandable that the above-mentioned connecting mechanism is used to connect with the drive mechanism / frame in the injection molding machine. In addition to the above-mentioned lug and flange structure, there are many other configuration methods, which will not be elaborated on here.

[0062] In some embodiments of this application, the reinforcing structure 6 is a reinforcing rib (not shown in the figure), the reinforcing rib is provided to avoid the T-slot structure 2, and a connecting mechanism (not shown in the figure) is provided on the side of the reinforcing rib away from the connecting surface 12.

[0063] The aforementioned reinforcing ribs are used to enhance the strength of the T-slot high-strength template structure of this application, and the connecting mechanism is used to connect with the drive mechanism / frame.

[0064] In some embodiments of this application, such as Figures 2 to 5 As shown, support feet 7 are provided at both ends of the lower side of the plate 1.

[0065] The aforementioned support foot 7 is used to support the entire plate 1. When the plate 1 is placed inside the injection molding machine, the support foot 7 can contact the machine frame to support the entire plate 1.

[0066] The above description is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principles described in this application, and these improvements and modifications should also be considered within the scope of protection of this application.
